Berkeley City Property Owners to Pay For Energy Audits

Berkeley City Property Owners to Pay For Energy Audits | Green Building Operations - Systems & Controls, Maintenance & Commissioning | Scoop.it

Later this month, the Berkeley City Council is slated to approve a new law — designed to increase building sustainability and reduce greenhouse gas emissions — that will mandate new fees and recurring energy assessments for local property owners.

Duane Tilden's insight:

>" [...] The law would require payment of a $79-$240 filing fee, depending on building size, by property owners every 5-10 years. On top of that, property owners will be required to undergo building energy assessments on the same cycle, conducted by registered contractors, to the tune of an estimated $200 for a single-family home and up to $10,000 for large commercial buildings.

The goal of the new law, according to the city, is to make “building energy use information more transparent to owners and prospective renters or buyers,” and ultimately inspire more investment in energy upgrades. The law would replace existing minimum energy and water efficiency measures in Berkeley. The proposed ordinance would not require that upgrades are actually done, but will compile energy scores and summaries for city properties, and make them readily available online.

Explained city sustainability coordinator Billi Romain, “Rather than require a list of specific measures, it requires an evaluation of a building’s efficiency opportunities and identifies all available incentives and financing programs.”

Romain said the hope is that, by giving people a “road map” for potential improvements, they will be more likely to schedule them to fit in with other home projects, such as seismic work. In addition to cutting down on local greenhouse gas emissions, the new ordinance has several other goals, from reducing utility costs that cause local dollars to “leak out” of Berkeley, to creating a more comfortable, durable building stock, as well as fortifying the local “green” workforce. [...]

According to a city Energy Commission report on the ordinance, the assessments would take place on a five-year cycle for large buildings and every 8-10 years, or upon sale, for medium-sized and small buildings. Some of the costs may be offset by rebates and other incentives, and the program is set to include temporary “hardship deferrals” for those with financial constraints, and exemptions for high-efficiency buildings (see page 14).

Built in 1928 Chicago Apartment Building Energy Retrofit Achieves EPA Energy Star Certification

Built in 1928 Chicago Apartment Building Energy Retrofit Achieves EPA Energy Star Certification | Green Building Operations - Systems & Controls, Maintenance & Commissioning | Scoop.it
To say the 55-unit building in Chicago's South Shore neighborhood was in disarray when it was changing hands in 2009 would be an understatement.
Duane Tilden's insight:

>" [...] the building is among the first in the Midwest — and only three in Chicago — to achieve the Environmental Protection Agency's new Energy Star certification for multifamily buildings. Also receiving the designation were two condominium buildings in Chicago, 680 N. Lake Shore Drive and River City, at 800 S. Wells.

[...] Jeffery Parkway also stands as an example of how an older, smaller, affordable apartment building can be made more comfortable for its tenants while saving its owner cash in the long run.

Seeking a neutral third party to help them figure out the entire scope of a rehab project, the Soods obtained a free energy audit of the building and its systems from Elevate Energy, a Chicago-based nonprofit that works with consumers and businesses to improve energy efficiency.

Elevate looks at historical analyses of a building's energy use and compares it with similar buildings in terms of age and size. Then it performs an on-site performance assessment of the existing heating, cooling and lighting systems and makes recommendations for potential improvements.

[...]

"The average cost of a retrofit is about $2,500 to $3,000 a unit," Ludwig said. "We're not talking about huge-ticket items. A lot of times we are trying to identify the most cost-effective retrofit measures, how can we tighten the building envelope. It doesn't have to mean a new boiler is going in the basement."

However, in the case of Jeffery Parkway, it did mean a new steam boiler and new water heaters, among other upgrades.

The project was financially feasible because of a loan from nonprofit Community Investment Corp.'s Energy Savers loan program, which offers a seven-year loan with a 3 percent fixed interest rate for qualified upgrades made to buildings in the seven-county Chicago area and Rockford.

[...]

"We will cover any of the recommendations that show up in the energy assessment, and we'll also do other energy-related improvements," said Jim Wheaton, manager of the Energy Savers program. "This is not a program designed for the North Lake Shore Drive high-rise. It's designed for buildings affordable for working folks."

Multifamily buildings receive an Energy Star score of 1 to 100, and those that score above 75 can apply for the certification. Nautilus' building received a score of 99.

"The savings are tremendous," Sandeep Sood said. "We were facing, just on the gas bill, a $60,000 bill a year. As of last year, our bill was $18,000. It was an unbelievable savings." [...]"<

BEMS for Smaller Buildings $6 Billion Growth from 2014 to 2022

BEMS for Smaller Buildings $6 Billion Growth from 2014 to 2022 | Green Building Operations - Systems & Controls, Maintenance & Commissioning | Scoop.it
The market for building energy management systems (BEMS) for small and medium-sized commercial buildings is expanding as building owners and managers demand more energy savings and easier ways to manage energy use in their facilities, notes Navigant Research.
Duane Tilden's insight:

>" [...]“Lower expenditures on energy management in the small and medium-sized building market, along with the lower penetration of advanced controls and building management systems, has limited the penetration of BEMS in this sector,” said Noah Goldstein, research director with Navigant Research. “Given the increasing importance of energy savings, however, BEMS are poised to be a tool that enables savings in both cost and carbon emissions in small and medium buildings.”

The most rapid growth in the BEMS market for smaller buildings, according to the report, is expected to occur in Europe and Asia Pacific, where new construction and regulation are promoting the installation of BEMS equipment and in turn creating demand for associated services and software. In the North American market, BEMS sales are expected to be concentrated in software, driven by utility and regulatory initiatives that promote energy efficiency and building energy reporting.

Duane Tilden's insight:
>"Washington /PRNewswire / - Three North American industrial plants that recently deployed energy management systems (EnMS) are highlighted in new case studies from the Global Superior Energy Performance (GSEP) Energy Management Working Group (EMWG). These latest entries in the growing GSEP series explain how two Canadian plants, IBM and Lincoln Electric, and one U.S. plant, HARBEC, Inc., deployed ISO-compliant systems to manage their energy more efficiently while boosting competitiveness. GSEP, an initiative of the Clean Energy Ministerial, publishes the series in an effort to improve energy efficiency and mitigate carbon emissions around the globe. U.S. Case Study HARBEC, Inc. improved the energy performance of its specialty plastics manufacturing plant in upstate New York by 16.5%, primarily by managing its combined heat and power unit more efficiently. The plant's verified conformance with the international energy management standard ISO 50001 and its sustained improvements in energy performance earned HARBEC Platinum certification from the U.S. Superior Energy Performance (SEP) program, administered through the U.S. Department of Energy. View HARBEC Inc. case study. The USD$127,000 invested to implement SEP was paid back by the resulting operational energy cost savings within 2.4 years. The EnMS now saves the plant 6 billion Btu (6,300 gigajoules) annually and lowers energy costs by USD$52,000 each year at prevailing energy prices. HARBEC's real-time automated system continuously monitors plant equipment to sustain and continuously improve energy performance. [...] Canadian Case Studies IBM implemented an EnMS at its manufacturing facility in Bromont, Quebec, which helped it to reduce energy consumption by 9.2% and save CAD$550,000 in 2013. The savings came from 36 energy efficiency projects implemented as part of the EnMS. Tool modifications generated approximately 27% of the savings, while heating, ventilation, and air conditioning and exhaust reduction projects generated the other 73%. Equipment throughout the plant is now monitored using dashboards that show real-time energy use. View IBM case study. With the support of Natural Resources Canada (NRCan), IBM Bromont was certified for conformance with CAN/CSA ISO 50001 in 2013. NRCan's Canadian Industry Program for Energy Conservation provided plant staff with various energy conservation tools and services that assisted with EnMS development and certification. Lincoln Electric became CAN/CSA ISO 50001 certified after implementing an EnMS at its facility in Toronto, Ontario, which manufactures steel welding wire and industrial diesel-driven DC generator welding machines. With the help of NRCan, Lincoln Electric developed an EnMS that reduced the facility's energy consumption by 22% in 2013. View Lincoln Electric case study. Plant management was initially interested in an EnMS as a means to maintain competitiveness and reduce risks associated with volatile energy prices. The company learned that its successful EnMS implementation owes much to its corporate culture that actively encourages the identification of energy improvements and conservation measures. The plant expects its EnMS to lead to continuous improvement in overall plant energy consumption. [...]"<

Advanced Controls Devices for HVAC in Buildings shows growth

Advanced Controls Devices for HVAC in Buildings shows growth | Green Building Operations - Systems & Controls, Maintenance & Commissioning | Scoop.it
Worldwide revenue from advanced HVAC controls is expected to grow from $7 billion annually in 2014 to $11.7 billion in 2023, according to a new report
Duane Tilden's insight:

BOULDER, Colo.--(BUSINESS WIRE)--Heating, ventilation, and air conditioning (HVAC) in commercial buildings typically accounts for roughly 40% of total building energy consumption. While advancements have been made in the efficiency of HVAC equipment, the actual energy consumption of HVAC equipment depends largely on their operation – which can be made much more efficient and less energy-intensive through the application of advanced HVAC controls. [...]

“The drive to reduce energy use in commercial buildings has put a spotlight on improving the efficiency of HVAC systems, and HVAC controls retrofits offer a compelling value proposition through reduced energy consumption in existing buildings.”

[...]

New building certification and benchmarking regulations are driving faster retrofits of controls in existing buildings, according to the report, and changing how automation is designed into new buildings. The wider adoption of open standards for controls functions (such as BACnet), and of communications based on the Internet Protocol (IP) suite and Ethernet connectivity, is expected to help bring advanced HVAC technology to a wider market.

Utilities and Energy Efficiency - How to Bridge the Gap

As much as such improvements can provide positive financial returns to utility customers, the utilities themselves face some very real financial barriers to offering customer energy efficiency programs.

Duane Tilden's insight:

>The inherent conflict between a utility’s business objectives and the objectives of customer energy efficiency programs has long been recognized. Alternative regulatory mechanisms can be implemented that not only make utilities indifferent to the amount of energy they sell, but that also can provide positive earnings from their customer energy efficiency programs. Alternative regulatory mechanisms such as “decoupling,” (separating an utility’s revenues from the amount of energy it sells to customers) are in place in a growing number of states.

Since the premise of these alternative regulatory mechanisms is that they can protect utilities from suffering financial harm from energy efficiency programs, ACEEE examined the experiences of a selected group of utilities to find out how well such regulations have worked. The utilities we selected all have relatively large-scale energy efficiency programs that serve all types of customers. We interviewed utility program managers and executives as well as clean-energy advocates and regulators. We also examined the financial performance of these utilities as represented by their stock performance.

What we found is that these utilities all have performed well financially. We found no evidence to suggest that energy efficiency programs have had negative effects on shareholder returns. While addressing utility business concerns with energy efficiency programs is clearly important, doing so is really just one part of comprehensive policies and regulations that support customer energy efficiency programs. Other keys to successful energy efficiency programs include:

Strong commitments to energy efficiency by regulators and utilities,Ongoing collaboration among utilities and stakeholders,Shared sense of purpose and common goals, andWillingness to experiment and learn from experiences.

Qualifications and Documents for Comprehensive Reserve Fund Studies

Qualifications and Documents for Comprehensive Reserve Fund Studies | Green Building Operations - Systems & Controls, Maintenance & Commissioning | Scoop.it

As of May 5, 2001, the Condominium Act 1998 requires all existing and new condominium corporations to have a "Reserve Fund Study" undertaken. This article outlines some of the key aspects of Reserve Funds and the Studies.

 
Duane Tilden's insight:

>[...]The regulations to the Condominium Act stipulate the minimum liability insurance requirements; $1,000,000.

6. What Information Does The Corporation Need To Provide? 

Once you have hired a consultant, he/she will require information about the condominium corporation. This will include the following:

As-built drawings and specifications.The Declaration and Description.Reciprocal cost sharing agreements.Previous reserve fund studies.The most recent audited financial statements.What the current annual contribution to the Reserve Fund is.Repairs or replacements to the common elements that have already been completed and when. Similarly, scheduled future work needs to be accounted for.A summary of problems being encountered by the Corporation that should be reviewed. As an example, water penetration concerns.7. What Is The Process?

The process is as follows:

The consultant is provided the above information. One of the most important are the drawings. They will be reviewed prior to visiting the site in order for the consultant to become familiar with the overall design and construction schemes.Site inspection. In order to have an understanding on the current condition of the common elements, visual inspections are undertaken. Problem areas noted above can be reviewed. After the first study, the next study update can be completed without a site inspection. The next update must include a site inspection.The report is then prepared (see next question). The drawings are used to "take-off" quantities such as roofing, exterior wall cladding, asphalt, hallway finishes etc that will assist in preparing the replacement/repair cost budgets. It is recommended that a draft report should be submitted in order for the Board and Property Manager to review it prior to it being finalized. The consultant should be available to attend a meeting to review the report.Upon receiving direction from the Board of Directors, the Reserve Fund Study is finalized and submitted. [...]

Today more than ever, businesses are concerned with maximizing operational efficiency, minimizing costs, and seeking out untapped revenue streams. At the same
Duane Tilden's insight:

>Large energy users like many commercial, institutional, and industrial organizations have a unique opportunity to act as a “virtual power plant” while reducing their real-time demand for electricity—and opening up a new revenue stream. This strategy, known as demand response, is not only a cost-free way to reduce energy usage, but also it generates payments for participating businesses simply for being on call.

 

Demand response providers work with commercial, institutional, and industrial businesses to identify ways for facilities to reduce energy consumption without affecting business operations, comfort, or product quality. In turn, those facilities agree to reduce their demand during strategic times so that utilities and grid operators can improve reliability during times of peak demand. Demand response also helps increase economic efficiency in regional energy markets and integrate renewable generation capacity into generation systems.

 

Demand response can be considered a form of strategic energy efficiency, but what about long-term, persistent energy efficiency, a second key to a comprehensive energy management program? In even the most high-tech, LEED Platinum certified buildings, it can be very difficult to ensure efficient operation over time. [...]<

Virtual Energy Audits: The Next Big Thing in Buildings?

Virtual Energy Audits: The Next Big Thing in Buildings? | Green Building Operations - Systems & Controls, Maintenance & Commissioning | Scoop.it
Virtual energy audits use software to collect meter data, weather information, etc. and algorithms to develop energy efficiency recommendations.
Duane Tilden's insight:

>The goal of any energy audit is to identify savings by analyzing data, determining how and where a building is using energy, and then providing operational and capital energy efficiency measures that improve overall performance.

 

A traditional ASHRAE Level II Audit includes a manual inspection of data related to a facility’s Building Envelope, Lighting, Heating, Ventilation, and Air Conditioning (HVAC), Domestic Hot Water (DHW), Plug Loads, and Compressed Air and Process Uses (for manufacturing, service, or processing facilities). Analysis is conducted to quantify baseloads and account for seasonal variation. A Level II Audit will also include an evaluation of lighting, air quality, temperature, ventilation, humidity, and other conditions that may affect energy performance and occupant comfort. The process also includes detailed discussions with the building owners, managers, and tenants – there is a lot you can learn just by talking to people about what they think is working and not, what the financial objectives of the organization are, and how that should feed into the recommendations.  [...]

 

Ok, I get it: So what’s a virtual energy audit?

Essentially a virtual energy audit is much like a traditional audit: the goal is to synthesize a whole bunch of data and come up with a list of recommendations that are going to deliver you the biggest bang for your buck. Unlike a detailed ASHRAE Level II audit, it’s better to think of virtual audits as delivering against the 80/20 rule. For a lot less physical effort, it’s going to get you about 80% of the detailed insights that a traditional ASHRAE Level II energy audit would deliver. And for many organizations, that’s OK – because their biggest, most obvious energy hogs are the ones driving the biggest bills at the end of the month.<

Energy Management - Determining Load Factor to Maximize Control

Energy Management - Determining Load Factor to Maximize Control | Green Building Operations - Systems & Controls, Maintenance & Commissioning | Scoop.it
Understanding load factor is an important component to energy management and learning how to take control of your electricity use.
Duane Tilden's insight:

>Load factor is a ratio or percentage of the consistency of your electricity consumption – in other words, load factor is a way to answer the “how ‘spikey’ is your load?” question. The easiest way to understand your own load factor is by looking at your real-time energy data. Not only will your energy data indicate your load factor, but it will also highlight other important aspects of your electricity use over time that will enable you to make smarter energy management decisions.

While looking at your real-time energy data is the best way to accurately get your load factor, you can approximate it from your utility bill information. To manually find out your load factor, divide your total consumption (in kWh) by the number of hours in your billing period. Then, divide the result by your peak demand during the billing period, and the number you compute is your load factor. A load factor closer to 1, or 100%, indicates that you are using energy more evenly or consistently over time. It might also mean you are reducing your peak demand or otherwise avoiding spikes.<

101-Year-Old Toledo Museum of Art Building Goes Temporarily "Off the Grid" After 20 Years of Implementing Green Initiatives - absolutearts.com

Museum briefly becomes a provider, rather than user, of electricity

Duane Tilden's insight:

>TOLEDO, OHIO–On Tuesday, May 21 the Toledo Museum of Art achieved a milestone in its 20-year effort to reduce energy consumption: its 101-year-old Beaux Arts main building stopped drawing power from the electrical grid and actually started returning power to the system. The ongoing process, which incorporates using sustainable energy practices such as solar power, energy-efficient lighting, micro turbines and chillers, has resulted in hundreds of thousands of dollars in cost savings over the years. 


[...]

Bernhard cited lighting as a good example. The first generation of LED lights weren’t suitable for illuminating and protecting art, so they were bypassed at the time. Now that the technology has dramatically improved, LED fixtures are now being introduced into the galleries, where lights frequently burn out from continual usage. The new lights not only save energy but last much longer, decreasing labor costs associated with the constant replacement of bulbs. The lighting in the renovated lot is also provided by new LED fixtures, which provide greater illumination while using less electricity.


     Bintz and Bernard also added new micro turbines and chillers to the power plant at TMA’s world-famous TMA Glass Pavilion during last year’s energy upgrade. The heat from the building’s working glass hot shop is recycled into the rest of the building during cold months. While generating electricity, the micro turbine waste heat is used to heat the building in the colder months and generate chilled water for air conditioning in the summer.<

Energy efficient technology and services for the building sector will double by 2022, according to a new report ...

Duane Tilden's insight:

>"[...] Since buildings account for a large portion of national energy consumption, most of the governments in the Asia Pacific region have taken steps to promote energy management and energy efficiency in both new construction and existing buildings. 

[...]

"With about 40 per cent of the world’s building stock, Asia Pacific represents a major portion of global real estate,” he said.

"Growing concerns about air pollution in Chinese cities, in particular, is expected to further drive investment in energy efficiency technologies to reduce China’s demand for coal-based electricity. 

"The market for energy efficient buildings is expected to double in the next eight years, reaching nearly $92 billion in annual revenue by 2022.”

The largest segment of the energy efficient buildings market in Asia Pacific today is advanced lighting [...]

"The commercial buildings sector in the region will experience a significant increase in the adoption of these products in the coming years," Bloom said. Entitled“Energy Efficient Buildings: Asia Pacific”, the report examines the trends for energy efficient building technology and services in the Asia Pacific region. 

It covers three main areas of technology – HVAC, energy efficient lighting, and commercial building automation – as well as the energy service company (ESCO) sector. 

The convergence of building automation, information technology, and wireless communications is another area of growth identified by Navigant Research.

A separate report examines the state of the global wireless building controls industry, including global market forecasts for wireless node unit shipments and revenue through 2023.

Wireless controls can be used to link devices found in a variety of building systems, including heating, ventilating, and air conditioning (HVAC), lighting, fire and life safety, and security and access. 

In addition, they often provide networked control in buildings or areas where wired controls are simply too challenging or expensive to install. 

Worldwide revenue from wireless control systems for smart buildings is expected to grow from $97 million annually in 2014 to $434 million in 2023.

[...]

While the adoption and deployment of wireless systems based on standard technologies and protocols, such as Wi-Fi, Zigbee, and EnOcean, are increasing, most wireless devices and control networks used today utilize proprietary, vendor-specific wireless communications technology. 

That is likely to change as the demand for interoperability grows, according to the "Wireless Control Systems for Smart Buildings" report. "<

Lighting Controls in Buildings, Demand Management and Microgrid Development

Lighting Controls in Buildings, Demand Management and Microgrid Development | Green Building Operations - Systems & Controls, Maintenance & Commissioning | Scoop.it
Lighting control systems can help microgrids shed load, improve demand response, use resources efficiently, and offer greater overall reliability.
Duane Tilden's insight:

>" [...] Lighting Control Facilitates Load-shed Strategies

Load shed, or the ability to quickly reduce electricity use during peak periods, is critical to ensuring microgrid reliability. Because lighting uses a considerable proportion of building peak electrical loads (30% of peak electricity),1 and because reduced light levels deliver immediate reductions in electricity, lighting control is one of the simplest and most predictable demand response solutions.

The reduction of lighting load also provides a reduction in HVAC cooling load during the summer, which is the most common peak electrical period.  Furthermore, since dimming is typically unobtrusive when it is executed over a period of time (as little as 10 seconds), lighting control is a viable option for immediate emergency response.

Dimming as a load shed strategy is highly effective because the human visual system has the ability to accommodate a wide variety of light levels with minimal effect on the occupants2,3.  When a demand reduction is required a gradual dimming of electric lighting can reduce light levels by 35 percent before 20 percent of the occupants attempt to intervene.  Response time is essentially instantaneous, typically has little impact on occupant comfort, and demand savings from lighting are more predictable than those from HVAC response.

Light management systems have the capability to automatically trigger a demand response event from a utility signal or from time clock scheduling. Therefore, a predictable and effective demand response strategy can be automatically implemented while going virtually unnoticed to the building occupants.

Energy codes, standards, and green building certifications such as ASHRAE (American Society of Heating, Refrigerating, and Air Conditioning Engineers) 90.1, IECC (International Energy Conservation Code), California Title 24, ASHRAE 189, IgCC (International Green Construction Code), or LEED (Leadership in Energy and Environmental Design) now include lighting controls as a part of a whole-building energy strategy.

There are subtle differences for each code/standard/certification, but some general requirements and/or credits include: required lighting control for most areas (manual or automatic), automatic lighting shut-off, some automatic receptacle shut-off, daylight controls for daylit spaces, automatic shut-off of exterior lighting during daytime hours, and various levels of occupancy/vacancy control. As a result of buildings updating their basic lighting control infrastructure to meet code, they are increasingly becoming capable of connecting to a microgrid, without the need for additional significant investments.

6 Schemes to Implement for Plant ISO 50001 Certification

6 Schemes to Implement for Plant ISO 50001 Certification | Green Building Operations - Systems & Controls, Maintenance & Commissioning | Scoop.it

During a webcast  [...] representatives from the US Department of Energy and Underwriters Laboratories walked through the details of the just-released energy management standard, and how companies can get on board, quickly.

Duane Tilden's insight:

>"When the standard achieves widespread adoption, it's estimated that ISO 50001 could influence up to 60 percent of the world's energy use.  [...]

ISO 50001 requires continuous improvement, but not specific requirements, which is where the ITP program comes in, to have specific requirements of improvement. The value of the certification, Scheihing said, is that for the first time it provides a framework for continual improvement for facilities on energy performance, and across the entire organization.

To be certified, you have to conform to the ISO 50001 management standard, and you have to improve your energy performance, and get both aspects certified under a third party. There are 24 companies working in the pilot mode of ISO 50001, across all types of manufacturing sectors and at all sizes.

Between 2008 and 2010, five initial facilities in Texas were piloted, and have been certified to date. Scheihing said the energy improvements achieved at the facilities ranged from 6.5 percent to 17.1 percent over a three-year period.

Among the initial feedback from the pilot project include the benefits of having a cross-functional plant energy management team that goes beyond just operations or engineering means that energy management becomes a shared responsibility, and that makes it much easier to incorporate significant changes in energy use.

One of the biggest shifts that the pilot projects found was that as a result of going through ISO 50001 certification, energy management became a way of doing business, instead of a project-by-project undertaking.  [...]

 

Scheihing laid out six steps that any organization can take to get started on ISO 50001 today: 

Secure support from top management;Collect, track, and analyze energy data;Identify key energy uses;Establish a baseline;Identify energy-saving opportunities;Prioritize opportunities

The Department of Energy has created a new website for energy management, which lays out an overview of ISO 50001 and offers case studies and tools to help companies undertake those first steps.

Jerry Skaggs from UL DQS followed on Scheihing's presentation to walk through each of the six steps, as well as a checklist for organizations to follow once they've gone through the process to ensure proper implementation and follow-through.

In the end, there are a number of benefits to effectively implement an energy management system, including: 

• Reduced operational and overhead costs lead to increased profitability
• Reduced air emissions, such as GHGs
• Increased efficiency of energy sources
• Increased assurance of legal, internal compliance
• Variables affecting energy use and consumption are identified
• Increased understanding of energy use and consumption via defined methods, processes of data collection 

UL DQS, which brings the Management Systems Solutions division of Underwriters Laboratories together with DQS, a German management certification company, offers a number of specialized services for helping companies assess and implement opportunities for energy management, including ISO 50001 certification.  [...] "<

CEC Delays Energy Benchmarking and Disclosure Requirements 2 Years for Smaller Buildings

Note: Compliance with AB 1103 is not suspended, and will continue to be required, for the sale, lease, or financing of buildings over 10,000 square feet that are otherwise subject to the regulations based upon occupancy type.

Significant barriers to compliance with AB 1103

An Emergency Rulemaking Action requires a description of specific facts justifying the immediate action. In justifying the two-year delay, the CEC explained that several stakeholders had expressed concerns about significant barriers to compliance with AB 1103. The CEC noted the following factors in justifying the two-year delay:

Some utilities have required tenant consents before releasing utility usage data despite letters sent from the CEC to utilities in July 2013 prohibiting such requirement. This requirement to obtain tenant consents significantly increases compliance costs.

Smaller utilities have expressed concerns with their ability to comply given limited staff and resources.

The Portfolio Manager platform and software has experienced significant technical problems.

The expansion in scope to smaller buildings would increase the number of compliance requests received by utilities, impeding their ability to address barriers to compliance.

Smaller building owners may lack the expertise, resources, or capacity necessary to overcome current barriers to compliance without incurring undue expense.

Based on initial disclosure data following the January 1, 2014 implementation, it became apparent that "the required disclosures were not being made for the majority of transactions for which they were required."

The development of best practices approaches is lowering compliance costs and paving the way to greater compliance. The additional two years will facilitate lower costs and higher compliance rates before further expanding the program to smaller buildings.

The California Energy Commission ("CEC") issued an Emergency Rulemaking Action to delay the implementation of the California Nonresidential Building Energy Use Disclosure Program ("AB 1103") relating to buildings between 5,000 and 10,000 square feet until July 1, 2016.
Duane Tilden's insight:

>"[...]Compliance with AB 1103 is not suspended, and will continue to be required, for the sale, lease, or financing of buildings over 10,000 square feet that are otherwise subject to the regulations based upon occupancy type.

Significant barriers to compliance with AB 1103

An Emergency Rulemaking Action requires a description of specific facts justifying the immediate action. In justifying the two-year delay, the CEC explained that several stakeholders had expressed concerns about significant barriers to compliance with AB 1103. The CEC noted the following factors in justifying the two-year delay:

Some utilities have required tenant consents before releasing utility usage data despite letters sent from the CEC to utilities in July 2013 prohibiting such requirement. This requirement to obtain tenant consents significantly increases compliance costs.

Smaller utilities have expressed concerns with their ability to comply given limited staff and resources.

The Portfolio Manager platform and software has experienced significant technical problems.

The expansion in scope to smaller buildings would increase the number of compliance requests received by utilities, impeding their ability to address barriers to compliance.

Smaller building owners may lack the expertise, resources, or capacity necessary to overcome current barriers to compliance without incurring undue expense.

Based on initial disclosure data following the January 1, 2014 implementation, it became apparent that "the required disclosures were not being made for the majority of transactions for which they were required."

The development of best practices approaches is lowering compliance costs and paving the way to greater compliance. The additional two years will facilitate lower costs and higher compliance rates before further expanding the program to smaller buildings."<

Maintaining High Performance HVAC Control Systems for Cost Savings in Building Operations

Maintaining High Performance HVAC Control Systems for Cost Savings in Building Operations | Green Building Operations - Systems & Controls, Maintenance & Commissioning | Scoop.it

The performance level of a building is directly related to the performance level of its control systems. You cannot manage a high performance building without high performing control systems.

 
Duane Tilden's insight:

>"We rely on control systems to monitor and manage our building systems. For the most part it’s been assumed that once the control system is installed and configured it will work for years with little attention and minimal maintenance. Some systems may be trouble-free, but the majority of them will need regular attention and maintenance. Over time hardware will fail, software parameters and versions change and slowly the control system will “drift” from its original configuration and performance.

The role of control systems is somewhat undervalued. When you examine the most complex system in most buildings, the HVAC infrastructure, you find that it’s the HVAC control system, not the HVAC equipment, which produces the most operational issues and is the leading cause of inefficient energy use. Lawrence Berkley National Laboratories examined 60 buildings and found the highest frequency of common problems with HVAC was in the control system. Texas A&M research determined that of the operational and maintenance measures that could produce significant energy savings, 77% of the savings were from correcting control problems. 

Maintaining a high performing control system involves regular maintenance, software and data management and organizational policies. The issues that can cause problems with a building control system are the same challenges all of us have had at one time or another with our computer or smartphone: problems related to software, hardware, communications networking and “user” mistakes. What follows is an overview of some of the typical control system issues and recommendations as to how to keep it performing at a high level."<

Boston Housing Authority to invest $11m in energy efficiency and infrastructure upgrades for Public Housing

The Malden Housing Authority will spend more than $11 million to make its public housing units more energy efficient, work officials believe will pay for itself.
Duane Tilden's insight:

>The 250-unit complex has a central power plant with utilities distributed to each building through pipes installed in the 1950s. The pipes are in poor condition, Finn said, which results in uneven distribution of heat and water pressure. “Those pipes are a problem; they are aging in place,” he said.

The new system will feature one energy-efficient boiler for every two units in the 58 Housing Authority buildings on Newman Road, Finn said. The old pipes will remain and could be used by the authority or the city as underground electricity conduits, he said. The work on Newman Road is expected to cost $4.3 million.

The Housing Authority received the 20-year $11.27 million bond through MassDevelopment , an entity created by the Legislature in 1998 to act as a finance and development authority.

“We’re pleased to support the Malden Housing Authority with this low-cost financing to improve homes for low-income families, reduce the cost of utilities for the authority’s developments, and to support the Commonwealth’s goal of improving energy technologies and efficiencies, resulting in reduced cost,” MassDevelopment chief executive Marty Jones said in a prepared statement.

For the bond financing agreement, the authority will pay a fixed interest rate of 4.12 percent to East Boston Savings Bank, which is loaning the funds. But the bank was only able to do that by entering into an interest-rate swap agreement with another institution, PNC Bank.

The move allowed East Boston Savings Bank to offer a fixed-rate loan, which the Housing Authority needed in order to comply with federal housing standards, said Joseph Leary, vice president of East Boston Savings Bank.<

How Real Estate Energy Managers Can Use Big Data to Schedule Building Energy Retrofits

How Real Estate Energy Managers Can Use Big Data to Schedule Building Energy Retrofits | Green Building Operations - Systems & Controls, Maintenance & Commissioning | Scoop.it
Big Data remains a fairly nebulous concept for many real estate professionals, including those who stand to gain tremendously from it right now: real estate energy managers.
Duane Tilden's insight:

>To effectively time energy retrofit measures, energy managers can first develop those measures. New energy analytical tools such as FirstFuel identify and develop measures, and even estimate a range for capital cost. It does this analysis remotely over the course of a day just by analyzing hourly electricity data (which is sometimes also stored by the utility); no time-intensive on-site energy audit is required. Another new tool is Retroficiency, which provides a high-level look at energy performance improvement potential using the same interval data and, with minimal additional data from the IWMS, can further develop retrofit measures to investment-grade level.


After identifying energy-retrofit measures for the portfolio using remote energy analysis tools or more standard on-site energy analysis, energy managers can create a new retrofit measures database in the IWMS. Having this new database on hand enables managers to integrate energy retrofit opportunities with space management, maintenance and capital upgrade needs, and potentially other real estate issues. Such integration drives down the incremental cost of an energy retrofit, which is the gross cost minus the avoided cost of otherwise required capital or space upgrades.<

DIY Reserve Study Site Launched

CALABASAS, Calif., Oct. 24, 2013 /PRNewswire-iReach/ -- Association Reserves, a well-known provider of reserve study services in the United States, recently announced its decision to launch a new website dedicated to their Do-it-Yourself Reserve Study kit. 

 

Duane Tilden's insight:

>According to an article written using data from Association Reserves' 30,000 reserve studies, 70 percent of associations in the United States are "underfunded." This puts many organizations at an increased risk of special assessments, deferred maintenance, declining property values, and board member liability. According to the company, by accounting for the ongoing cost of common area deterioration and then properly funding reserves, boards are able to responsibly prepare for their associations' future expenses.

"Our goal is to eliminate all excuses for board members not to be aware of the current strength of their Association's reserve fund and the funding plan necessary to perform common area repairs & replacement in a timely manner," says Robert Nordlund, PE, RS, the company's founder. "The path from underfunded to appropriately-funded is a journey and a Reserve Study provides the necessary road map."<

Mobile Technology News and Information
Duane Tilden's insight:

>Ossia's patented smart antenna technology uses phased arrays to transfer power without the use of inductive coils, ultrasonic waves, magnetic resonance, charging pads or mats. The Cota technology consists of two parts: a charger and a receiver. The Cota-powered charger automatically locates Cota receivers built into devices or batteries, and delivers signals that are sent omnidirectionally. Once they hit the charger, these signals follow the same path back to the receiver, focusing energy at the exact location of the device. Cota continuously streams power to multiple devices, even as they move around a room. The laws of physics make the Cota technology inherently safe, naturally avoiding anything that absorbs energy, such as people, pets and even plants.<

Industrial networking expands PLC functionality | Plant Engineering

Industrial networking expands PLC functionality | Plant Engineering | Green Building Operations - Systems & Controls, Maintenance & Commissioning | Scoop.it
Combining real-time Ethernet with visualization, control, and communication capabilities allows PLCs to open the door to a new level of visibility and control for manufacturers.
Duane Tilden's insight:

>The days when workers served as the brain and brawn in manufacturing are long gone, while human-machine interaction has become commonplace on the factory floor. A prime example of this is the PLC, which has been the workhorse in automation and manufacturing industries across the board for many years. By interfacing with everything from sensors and machine guards to motion control and advanced identification devices, PLCs ensure operations run smoothly (see Figure 1). Through the flexibility offered with PLCs, manufacturers can manage multiple machines at once—achieving a higher level of integration and process automation machines and improving production quality and cost of operation. 

 

The benefits of the PLC are well known. Their contributions toward efficiency enhancement and the behind-the-scenes support of industrial Ethernet make this heightened control possible. Together, these technologies make communication between humans and machine a seamless, profitable combination. Consisting of various protocols, industrial Ethernet was developed with deterministic capabilities to provide a cost-effective alternative to legacy automation systems. 

 

With advanced capabilities, sophisticated functionality, and simplified installation, the PLC is a cornerstone of modern manufacturing. However, to effectively use these devices, users must understand the crucial role networking plays and the individual requirements that must be considered for an effective solution.  [...]<

Wireless Transmission of Energy in Buildings - Building Automation

Wireless Transmission of Energy in Buildings - Building Automation | Green Building Operations - Systems & Controls, Maintenance & Commissioning | Scoop.it

Energy harvesting wireless technology becomes more attractive for OEMs as a basis technology for products and solutions that contribute to a building’s efficient energy management. The wireless modules gain their power from the surrounding environment... 

Duane Tilden's insight:

>Energy harvesting technology enables batteryless automation devices and systems to make buildings more energy-efficient based on sustainable, resource-saving technologies that eliminate the need for batteries. [...]

 

 

In a complex commercial building scenario, EnOcean Link can be implemented on a central device, like a control server, which controls the whole building, holds the automation intelligence, and can be physically located outside the building (in the cloud). Several gateways in the building record radio telegrams from thousands of distributed batteryless wireless sensors and relay receivers, and send back information or command data when needed. These gateways are connected to the control server by a backbone, which does not have to be based on EnOcean radio, or even be wireless. The middleware, located in the central unit, interprets all telegrams received by the gateways and provides them to the automation system.

 

High energy efficiency goals demand flexible automation systems for all kind of buildings that cover several areas. This particularly affects retrofit projects, where the intelligent control of energy consumption is the key factor for a building’s improved energy and carbon footprint. Energy harvesting wireless technology fulfills the demands for today’s and tomorrow’s automation and energy management systems. [...]<
