Developing affordable zero-net energy (ZNE) multifamily housing requires unique technical and financing models. Two San Diego developers have demonstrated the success of such development models in supporting California's bold ZNE goals.

Automated demand-response (AutoDR) systems use Internet-based electricity pricing and demand-response signals to initiate preprogrammed control strategies that provide fully automated management of building energy use. When electricity prices are high or when the grid is nearing full capacity, these ...

To better understand the problem of mold occurrence, the California Energy Commission sponsored an investigation, led by the Gas Technology Institute, into the causes of moisture intrusion. This research consisted of laboratory and field studies of structures that are designed to keep building materials ...

The Lawrence Berkeley National Laboratory led a demonstration project that showed that alternative, direct-current (DC)–based power distribution systems can reduce the total system energy use in a data center by 5 to 7 percent compared to the most efficient alternating current (AC) systems and by ...

A desk lamp has been developed to provide individually controllable uplighting and downlighting. The designs incorporate improved optics and features that will enable low-cost manufacturing. The California Lighting Technology Center worked with Full Spectrum Solutions to develop the products. Full ...

An innovative wireless lighting control, monitoring, and management system developed by Adura Technologies is easy to install, cost-effective, and can provide significant energy savings. It eliminates the costly and time-consuming installation of control wiring and can be easily installed by facilities ...

A new technology that reduces ventilation rates during slow periods makes it possible for restaurants and institutions to significantly reduce the amount of wasted energy. Lower fan speeds also means less noise. The concept calls for control of kitchen ventilation-fan speed based on the amount of ...

A hybrid fixture featuring light-emitting diodes (LEDs) and either an incandescent lamp or a compact fluorescent lamp (CFL), and integrated with an occupancy sensor, addresses both energy and security concerns. The design features a low-wattage, high-brightness LED that runs continuously during the ...

Researchers from Ecos Consulting and the Electric Power Research Institute (EPRI) worked with industry leaders and other stakeholders to develop test procedures and measure the efficiency of a sampling of internal power supplies used in today's electronic products. The researchers also presented their ...

Researchers at the California Lighting Technology Center (CLTC) at the University of California at Davis developed a new approach to daylighting called the Simplified Daylight Harvesting system (SDH) that is easy to install and provides automatic and continuous calibration. The system uses photosensor ...
