2621.实现家庭零能源消耗的策略:未来指导框架
[水利、环境和公共设施管理业] [2015-07-15]
While many of the basic concepts underpinning net-zero energy (NZE) buildings were pioneered in the United States, interest waned when energy prices declined in the early 1980s. Now, the Energy Independence and Security Act of 2007 is driving design parameters for higher levels of performance for federal buildings by 2030, and the U.S. Department of Energy (DOE) set a national goal in 2010 to achieve NZE in 50% of all commercial buildings by 2050.

2624.等效发光效率——发光器的发光效率标准化指数
[计算机、通信和其他电子设备制造业,水利、环境和公共设施管理业] [2015-07-15]
The luminous efficiency do make four impact factors confused such as existing of dissipated light,ability for transmission of lighting sources,distortion of visual effects and different values of power choosing during the luminous efficiency comparison under its current definition.In this paper,the equivalent luminous efficiency was introduced based on the discussion of these factors which maintains the form of current definition of luminous efficiency while it sets the equivalent coefficient to make test results comparable under different measurement conditions,so as to be clear when we compare and evaluate the properties of energy-saving and luminescence of luminaries.

2627.通过简单廉价的高级电源板减少办公室插头负载
[水利、环境和公共设施管理业] [2015-07-15]
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.
