In recent technology demonstrations, data from occupancy sensors tracking plug load reductions with occupancy have shown energy-saving potential for both business and nonbusiness hours. Also, dense panel-level sub-metering has been used to quantify whole-building receptacle circuit energy consumption, energy savings, and return on investment for the whole building. Receptacle-level metering has been used to show the plug load energy consumption of individual devices and workstations. This paper documents the process (and results) of applying advanced power strips with various control approaches.

The spread of cool roofing has been more than prolific over the last decade. Driven by public demand and by government initiatives, cool roofing has been a recognized low cost method to reduce energy demand by reflecting sunlight away from structures and back into the atmosphere. By use of commonly available calculators, one can analyze the potential energy savings based on environmental conditions and construction practices.

Decomposition and defluorination of PFCs in wastewater by photo-induced hydrated electrons was well and firstly investigated in this paper.In this work the proposed method was tested to deal with PFCs containing wastewaters from a Teflon-manufacturing plant in Jiangsu Province, China.95.5％ of perfluorooctanoic acid (PFOA) was decomposed after 12 hours treatment and defluorination rate of PFCs could reach about 60％.PFCs were transformed into harmless fluoride, acetic acid and formic acid.It was suggested this system can efficiently decompose PFCs from fluorine chemical plant.In brief, this study demonstrates that the photo-reduction is a high efficient, energy-saving method which produced less-toxic products for PFCs removal, compared with activated carbon absorption and combustion.

The results showed that:applying Oxygen-enriched combustion technology to the existing cement clinker calcined equipments,the coal powder consumption,the volume of flue gas and CO2 concentration in the flue gas of unit cement clinker occurred regular changes,When the O2 concentration increased from 21％ to 30％,the coal powder consumption decreased by 17.78％,the flue gas volume was reduced by 12.73％ and the CO2 concentration in the flue gas increased to 76.57％.If the enterprise used the oxygen-enriched atmosphere of O2 concentration for 30％ to form the coal combustion,it can save coal about 71.87 t/d,equipment production capacity increase by 41.75％ and capture CO2 products about 2662 t.Every year,this resulted in the profit increasing 103 million yuan.

Congress, recognizing the potential for energy savings in the use of general lighting for illumination, requested in the Energy Independence and Security Act of 2007 (EISA 2007) that the Department of Energy (DOE) contract with the National Research Council (NRC) to conduct a study to assess the status of solid-state lighting (SSL) as a technology. The contract requested that the National Academies provide an objective and independent assessment of the current state of solid-state lighting and its future potential for accommodating the new minimum efficiency standards for lighting.

This project focused on the use of home energy ratings as a tool to promote energy retrofits in existing homes. A home energy rating provides a quantitative appraisal of a home's asset performance, usually compared to a benchmark such as the average energy use of similar homes in the same region. Home rating systems can help motivate homeowners in several ways. Ratings can clearly communicate a home's achievable energy efficiency potential, provide a quantitative assessment of energy savings after retrofits are completed, and show homeowners how they rate compared to their neighbors, thus creating an incentive to conform to a more >social standard. An important consideration is how rating tools for the retrofit market will integrate with existing home energy service programs. For residential programs that target energy savings only, home visits should be focused on key efficiency measures for that home. In order to gain wide adoption, a rating tool must be easily integrated into the field process, demonstrate consistency and reasonable accuracy to earn the trust of home energy technicians, and have a low monetary cost and time hurdle for homeowners. Along with the Home Energy Score, this project also evaluated the energy modeling performance of SIMPLE and REM/Rate.
