Groundbreaking Legislation to Increase Energy Efficiency

Groundbreaking Legislation to Increase Energy Efficiency | Lighting | Scoop.it

Groundbreaking “Pay-for-Success” legislation to increase energy efficiency in multifamily rental housing.Under the new law, intermediaries would raise private capital from philanthropic organizations and social impact investors, and then work with energy service companies and others to make water and energy improvements at HUD-assisted properties. Improvements could include adding insulation, replacing inefficient light and water fixtures, and adding new systems controls. An independent third party would then verify to HUD that reductions in energy and water usage are actually happening, and, if cost savings are realized,

Smart Sensors Mean Energy Savings

Smart Sensors Mean Energy Savings | Lighting | Scoop.it

At an estimated cost of $38 billion a year, lighting represents the largest source of electricity consumption in U.S. commercial buildings. For nearly 30 years, commercial buildings have relied on motion occupancy sensors -- a technology that a study has found can only accurately detect people about 75 percent of the time -- to control lighting and reduce energy costs.

DOE publishes LED outdoor lighting report, charts performance gains

DOE publishes LED outdoor lighting report, charts performance gains | Lighting | Scoop.it
The US Department of Energy (DOE) has released a Caliper Snapshot Report on outdoor LED area lighting products, based on the Lighting Facts program, one year after the release of the last outdoor-centric report. That report from August 2013 noted that LED lighting could not yet match high-pressure sodium (HPS) sources at the 400W level, but solid-state lighting (SSL) manufacturers have now delivered such products. Moreover, efficacy continues to escalate while light quality is also improved. The new DOE report is available for download on the agency's SSL website. The high-level trends include a move to 4000K CCTs for a slightly warmer look relative to the predominant 6500K LED lighting from prior years. At the top end, efficacy has hit 150 lm/W. The DOE said that outdoor area lighting products now comprise 30% of the agency's Lighting Facts database with roadway products accounting for 23%. The remaining 7% is spread among parking garage, canopy, and directional luminaires. The DOE noted that sixteen products in the database now feature efficacy above 120 lm/W. And that gain has come with light-quality attributes that typically result in efficacy penalties. For example, seven of the products have a CRI above 80 and only one has a CRI below 70. Such lighting delivers far superior color rendering to HPS lighting and make recognizing objects and pedestrians much easier for drivers. The 400W-HPS-equivalent LED products still fall at the lower end of the lumen-output range of HPS luminaires. But the LED products offer superior efficacy. Moreover, research has previously shown that the broader-spectrum LED lighting delivers better visibility at lower lumen-output levels. Indeed, tests at a Seattle LED roadway site two years ago revealed little decrease in object-recognition capabilities even as LED lights were dimmed considerably.

DOE invests $6M to support commercial building efficiency

DOE invests $6M to support commercial building efficiency | Lighting | Scoop.it

Washington - The Energy Department announced up to $6 million in funding to deploy and demonstrate four emerging energy-saving technologies in commercial buildings across the country. These projects will help businesses cut energy costs through improved efficiency, while also reducing carbon pollution. Last year, commercial buildings consumed about 20% of all energy used in the United States at an estimated cost of nearly $180 billion, and are responsible for 18% of total U.S. carbon emissions.

Saving Energy with Occupancy Sensors

Saving Energy with Occupancy Sensors | Lighting | Scoop.it

Occupancy sensors automatically turn off lighting in unoccupied spaces such as classrooms, conference rooms, public spaces, dormitories, and large offices. The typical office spends 29% of its electrical energy costs for lighting. Occupancy sensors can reduce this spend by 50% or more, at an energy savings of 5¢ – 20¢ per square foot. These sensors, which are usually infrared and/or ultrasonic, are most effective in those areas which are often unoccupied, such as corridors and conference rooms.

Xicato supports California energy-efficiency standards with integrated LED platform offering lighting controls

Xicato supports California energy-efficiency standards with integrated LED platform offering lighting controls | Lighting | Scoop.it
Silicon Valley companies are poised to deliver smarter solutions for retailers, hoteliers and facility managers as more stringent lighting efficiency requirements go into effect. San Jose, CA -- New Title 24 lighting efficiency regulations that took effect in California this month are likely to fuel demand for hardware and software solutions that Silicon Valley companies are poised to fulfill. Changes to California's Title 24 are designed to reduce energy consumption as much as 30% in commercial and public spaces. Most of the changes rely on electronic components and software controls that are becoming more common with the adoption of LED based lighting solutions. Advances have already been made for street lighting and parking lots and further efficiency gains will be realized. But the real energy savings ahead will be the result of more stringent regulations for indoor spaces, specifically retail, hospitality and office environments, where lighting is used for a significant part of the day. While there are many changes, of the new standards, the following will have significant impact on efficiency and create new opportunities for hardware and software integration and simplification. Occupant sensing lighting controls Occupancy sensing for most spaces will be a requirement going forward. Silicon Valley brings experience with sensors and software integration that allows the familiar wall-based sensor to be incorporated directly into the light source which means fewer switches and sensors on walls and ceilings and more importantly, simpler implementation which lowers costs. Automatic Daylighting Controls The new requirements for daylighting controls apply to buildings over 5,000 square feet and require that the floor plan specify daylighting controls for 75% of the space. Previously spaces that were over 2,500 square feet only considered daylight from sky-lights in the lighting calculation. Now, controls must automatically adjust the light and must also consider light from the side, windows, when the installed general lighting uses 120 Watts or more. Additional sensing of the ambient light and control management software will make this possible. Demand Response Controls Demand response is initiated in times of extremely high demand. The lighting must be able to respond to a demand response signal and lower power levels used by lighting by at least 15% compared to the buildings usage with all lighting at 100%. In the previous code this applied to retail buildings with sales floor areas of at least 50,000 square feet. This has now been lowered to all no residential buildings with at least 10,000 square feet. Dimming of LED and other light sources Installed LED lighting in non-residential spaces of at least 100 square feet must now include dimming controls that can adjust light output levels from 100% down to just 10%. Light sources other than LED must also be dimmable but the standards for LED lighting are the most demanding. Individually, any of these factors can lead to substantial energy reductions in lighting. As a group and with the other elements in Title 24, energy savings will be substantial. California has long led the nation in energy saving regulations and it's likely that other states and countries around the world will adopt many of the standards being set in California. Companies in the hardware and software space are already developing solutions that will fundamentally change how people think of lighting, transitioning it from an energy consuming commodity to a business asset. Xicato, for example, has developed an integrated LED module  -- XIM -- that incorporates communications, controls and sensors allowing businesses to save energy and add value to the ubiquitous light-in-the-ceiling. About Xicato Xicato is enabling the Internet of Lights and empowering architects, designers and building managers to create beautiful, smart spaces people love to live and work in. We design and build intelligent LED modules that integrate the best quality and most efficient light with software, sensors and connectivity.
