Cambridge Plans Massive Energy Efficiency Retrofit

Cambridge Plans Massive Energy Efficiency Retrofit | Green Building Design - Architecture & Engineering | Scoop.it
This medieval English city is investing $1.5 billion for energy upgrades for the entire city.
Duane Tilden's insight:

>It’s one thing to build super-energy-efficient new homes and offices – it’s another matter entirely to bring ancient buildings up to par. But the medieval university city of Cambridge, England, plans to do just that with a $1.5 billion retrofit program.

 

The newly launched Cambridge Retrofit Project aims to reduce carbon emissions from buildings 30% before 2050 through a massive, city-wide retrofit scheme.  [...]

 

While the primary goal is reduced energy consumption and carbon emissions, the program also aims to build up local businesses, create warmer homes and increase the value of properties.

 

Energy savings alone are expected to be worth $2.3 billion and the city’s carbon footprint, currently 830,000 tons a year, is expected to fall 1% a year, eventually reaching 500,000 tons a year as a result of the retrofit program.<

Formal consultation commences on the world’s first purpose built tidal lagoon | Specification Online

Formal consultation commences on the world’s first purpose built tidal lagoon | Specification Online | Green Building Design - Architecture & Engineering | Scoop.it
The formal consultation process has started on the world’s first purpose built tidal lagoon for Swansea Bay, with public exhibitions taking place at 18 locations around the Swansea Bay area until August 5.
Duane Tilden's insight:

>The proposed tidal lagoon will have a rated capacity of 240 Megawatts (MW), generating 400GWh net annual output. This is enough electricity for approximately 121,000 homes. 

In addition to generating electricity, the £650 million development will also provide visitor facilities and other amenities including art, education, mariculture and sporting/recreational facilities. The seawall is expected to be open to the public during daylight hours for walking, running, cycling etc, though access will be controlled in extreme weather.

LDA Design, the project masterplanners and landscape architects for Swansea Bay Tidal Lagoon, has completed the coordination of exhibition material for the public exhibitions. As part of the formal consultation for the proposed Development Consent Order (DCO) application by Tidal Lagoon (Swansea Bay) plc (TLSB), a new, virtual 3D programme has been prepared, which shows the proposed lagoon in the context of Swansea Bay.  <

Scientists Adding Color to Solar Panels

Scientists Adding Color to Solar Panels | Green Building Design - Architecture & Engineering | Scoop.it
If you have noticed the design and layout of solar panels around, you would have thought a minute or two about its aesthetics. Though not too bad, the dark
Duane Tilden's insight:

>The Institute is developing a SIS (semiconductor-insulator-semiconductor) variety solar panel. The package consists of a silicon substrate which absorbs light and converts it into electricity.[...]

 

The change in color does not make solar cells less efficient. The cell’s working is also not affected by the thickness of the conductive oxide layer. The SIS cell has the same simulated efficiency of around 20%.

 

The technology might later on use a type of inkjet printing that deposits the oxide layer with more flexibility, which would allow complex designs too. With this, solar cells could turn out to be part of beautiful architectural designs in future.<

Green Building Taking Off in Hospitality, Retail Industries

Green Building Taking Off in Hospitality, Retail Industries | Green Building Design - Architecture & Engineering | Scoop.it

Green building is taking off in the hospitality and retail industries, [...]  This year, retail owners that are building green for over half of their projects rose to 38%, up from just 18% in 2011. That's expected to rise to 52% by 2015. 

Duane Tilden's insight:

>"Green building has taken such hold in the industry that even sectors with unique challenges, such as retail and hospitality, are making stronger investments," says Harvey Bernstein, vice president at McGraw Hill Construction. "Clearly the benefits that owners are reporting are key reasons for their green building investments, and as they find better ways to measure those impacts and quantify the value to their sales velocity and to the well-being of their staff, customers and guests, we expect even more rapid engagement in green."

 

While lower operating costs are the most frequently reported reason for going green (66% of retailers, 73% of hotels), other factors are also considered very important in their decision-making process:

Utility rebatesProtecting/enhancing brand - just as important as costs for hotelsImproving ROI[...]Energy efficiency is still a key goal, recycling and waste management are also critically important. A strong majority say they require green practices from suppliers, especially on waste handling (75%). <

Go geothermal to maximize energy efficiency

A huge leap in energy conservation, and undoubtedly the most innovative of all energy saving tactics has its origins in the earth itself
Duane Tilden's insight:

>This geothermal system provides a quiet environment with a consistent temperature throughout the house or building; efficiently comfortable in the winter, and cool in the summer. The heating or cooling mode can be changed with a simple switch on the indoor thermostat. With virtually no use of fossil fuel, costs for heating and cooling for a typical 4,000-square-foot home can run as low as $2 per day/$60 per month.<

TD Bank Announces Energy-Saving Monitoring Data For Net-Zero Store

TD reports that the first net-zero bank built in the United States is exceeding expectations according to first-year monitoring data.
Duane Tilden's insight:

TD Bank's net-zero energy store opened on May 13, 2011. The U.S. Department of Energy (DOE) National Renewable Energy Laboratory defines a net-zero energy building (NZEB) as a residential or commercial building that produces and exports in a year at least as much renewable power as the total energy it uses.

 

[...]

A NZEB has two key energy features: The building is constructed with energy-efficient technologies that significantly reduce its energy demand, and renewable energy sources supply at least as much energy as the building uses over the course of a year.

Walgreens Wagers on Net-Zero Energy - Forbes

Walgreens Wagers on Net-Zero Energy - Forbes | Green Building Design - Architecture & Engineering | Scoop.it
Walgreens, the Deerfield, Ill.-based owner and operator of a whopping 8,000 retail pharmacy stores, is building America's first net zero energy retail store.
Duane Tilden's insight:

... the new store is projected to consume an estimated 200,000 kWh and generate an estimated 256,000 kWh annually, according to engineering calculations. To make this possible, Walgreens will equip the new store with more than 800 roof-top solar panels, two wind turbines, geothermal wells , LED lighting and energy-efficient building materials.

 

This smacks of the standard net zero energy building strategy, which Lawrence Berkeley National Laboratory has characterized like so: “‘net zero energy’ buildings (ZEB) follow the strategy of first achieving very aggressive reductions in energy use needed to provide the desired energy services, and then providing the remaining energy requirements with on-site renewable energy.”

Swansea Bay hydrokinetic project continues moving forward

Swansea Bay hydrokinetic project continues moving forward | Green Building Design - Architecture & Engineering | Scoop.it
Energy development group Tidal Lagoon Power Limited has reached a significant milestone in the development of a massive hydroelectric power project with the announcement of three design, build and deliver agreements.
Duane Tilden's insight:

>[...]According to TLP, the US$966.5 million project will consist of a 6-mile-long, 35-foot-high semi-circular sea wall that will enclose an area west of Swansea Marina.  The wall would be dotted along its length with a number of hydro turbines, giving the project a cumulative capacity of around 250 MW.

 

Each of TLP's three partners adds a unique quality to the project's development, the company said.  Costain will work in developing and managing the schedule for pre-construction and construction phases, developing construction methodology for civil engineering works including turbine and sluice structures, access routes and complex temporary works, including temporary bund for construction turbine housing.

 

Meanwhile, Atkins will provide engineering design and geotechnical expertise. TLP said this includes "designing both the turbine house and the innovate breakwater bund wall, which uses a combination of giant tubular sand bags protected by armor made up of different sized rocks."

 

Last, Van Oord is developing construction methodology suitable for the harsh off-shore conditions in Swansea Bay.

 

The Swansea is the first tidal lagoon power project envisioned by TLP, which said in May that it is considering a similar project off Wales' north coast. As much as 10,000 MW of tidal lagoon power potential in the United Kingdom, the group said. [...]<

The 21st century data center: You're doing it wrong | ZDNet | Green Building Design - Architecture & Engineering | Scoop.it
Outdated designs are keeping data centers from reaching their full potential.
Duane Tilden's insight:

>One example of this are data centers that use raised floors for cooling. Many IT pundits have discredited this method of cooling as wasteful, including Schneider Electric's territory manager for the Federal government and the ACT, Olaf Moon.


[...]

Cappuccio notes that engineering firms that are consulted to build data centers know about the newer and more efficient ways to do things. But rather than try something new, they prefer the stock standard cookie-cutter approach to creating data centers because it's fast and easy, he said.


[...]

"I've seen a lot of data centers being built that are too big," says Cappuccio. "We're finding people with data centers that are three to four years old when they realise they have far too much space, and are still providing air conditioning to those areas. So they begin to shrink them, putting up walls, bringing down the ceiling so they don't air condition the extra space."

Integrating Building into the Smart Grid

Integrating Building into the Smart Grid | Green Building Design - Architecture & Engineering | Scoop.it
It will take time to get from point A, today’s grid and building technologies and power markets to point B, a Smart Grid with intelligent buildings and transactive markets, but it can be done.

Via Joan Tarruell, Stephane Bilodeau, Hans De Keulenaer, Diedert Debusscher
Duane Tilden's insight:

>Transactive energy will play a critical defining role in grid modernization and shaping the Smart Grid.  Buildings, as noted in last week’s article consume 40% of the nation’s energy.  And while building owners can justify purchase decisions on energy savings as well as sustainability values, there’s another crucial factor for building owners to invest in technologies that reduce energy use and deliver self-generation.  That reason is to address the increasing vulnerability of the electrical grid to momentary and sustained power outages to both natural and human causes.

 

Buildings and their occupants are impacted by grid-related power outages.  The negative impacts range from reduced work productivity and decreased occupant safety and health to reductions in lifestyle standards.  Just like real estate values are higher for green buildings with LEED recognition, in the future, buildings that are grid-hardened may command premium prices because they preserve delivery of services regardless of grid status.  It is a compelling new variable in value propositions for tenants and occupants.<

Stephane Bilodeau's curator insight, June 2, 2013 6:13 PM

"A very important conference occurred in Portland, Oregon last week – the Gridwise Architecture Council hosted the first international Transactive Energy Conference.  The topic of transactive energy is so new that there’s no formal definition yet, but as the author of the Smart Grid Dictionary, here’s my suggestion.  Transactive energy is a software-defined, low-voltage distribution grid that enables market participation by distributed energy resources (DER) bidding generation of negawatts or kilowatts.  Transactive energy describes the convergence of technologies, policies, and financial drivers in an active prosumer market – where prosumers are buildings, EVs, microgrids, or other assets."

Biofuel Used to Make Stronger Building Materials

Biofuel Used to Make Stronger Building Materials | Green Building Design - Architecture & Engineering | Scoop.it
Biodiesel Fuel. Image Source: Tomorrow Is Greener Civil engineers have developed a tougher and more resilient form of concrete by using waste material created during the manufacture of biofuel as a proxy for cement.
Duane Tilden's insight:

Biofuel manufactured from cellulose materials such as wood and straw creates a residue called lignin, which is generally deemed a waste product and disposed of via burning or burial.

 

Engineers at the University of Kansas have found that the lignin has immense potential as a green building ingredient. When 20 per cent lignin waste was added to a concrete mix as a replacement for cement, the ensuing chemical reaction created a building material endowed with 30 per cent more strength.

 

The findings could have tremendous implications for both the biofuel and concrete industries, as well as the carbon footprint of the construction sector, which generates immense CO2 emissions due to cement production.

Seattle School Certified as World’s Fourth Living Building; First on West Coast

Seattle School Certified as World’s Fourth Living Building; First on West Coast | Green Building Design - Architecture & Engineering | Scoop.it
For those who aren't familiar with certified Living Buildings, this story is a great place to start. Congratulations to Bertschi School in Seattle!
Duane Tilden's insight:

A program of the International Living Future Institute, the Living Building Challenge (LBC) is widely considered the world’s most rigorous building performance standard. A Living Building generates all of its own energy through clean, renewable resources; captures and treats its own water; incorporates only non-toxic, appropriately sourced materials; and operates efficiently and for maximum beauty. A building must perform as designed for one full year of occupancy and pass a third-party audit before receiving certification as “Living.”

 

In order to meet LBC standards, Skanska USA’s green building team navigated the strict material requirements to source building products that did not contain any of the materials or chemicals on the LBC Red List. One of the greatest challenges in this effort was finding local manufacturers and vendors who were fully transparent about the chemical makeup of their products. The use of healthy materials promotes better indoor air quality, as well as furthers transparency in the building materials industry.

Nearly Zero-Energy Buildings and Offsite Renewables | Leonardo ENERGY

The facts and thoughts presented in this position paper reveal the complexity but also the potential organisational, financial and environmental benefits of integrating off-site electricity into the nearly-zero energy building concept. A thorough analysis of the EPBD's definition, existing concepts for nZEBs, aspects that influence the share of renewable energy and key issues around off-site renewables in nZEBs like energy cost, the advent of grid parity, metering schemes, ownership schemes of electricity generation, standardisation, monitoring, verification and enforcement has been done as a first contribution for starting a broader discussion around this topic.


Via Diedert Debusscher
Duane Tilden's insight:

Although nearly-zero energy building standards will be mandatory only for new buildings by 2020 the next and even more important question is how to transform the building stock to that level until 2050. The sheer magnitude of this challenge requires that in principle every building owner must be given a sufficient set of options to have a fair and equal chance to transform his property to nearly-zero energy standard. Thus electricity from on-site, nearby and off-site sources must be a natural part of the set of options.

more...
Diedert Debusscher's curator insight, March 12, 2013 4:26 AM

The European Performance of Buildings Directive (EPBD) does not consider off-site renewables as an option to cover the (very low amount of) energy required by nearly Zero-Energy Buildings (nZEB). This is surprising, as electricity consumption in buildings is expected to rise due to increased uptake of heat pumps and as electricity supply is on a path toward decarbonisation.
