[RenewableEnergyAccess.com] California-based XsunX has plans to seek Leadership in Energy and Environment Design (LEED) certification from the U.S. Green Building Council for the use of its Power Glass technology in green building design and construction. Power Glass is a type of building integrated photovoltaic (BIPV) technology applied directly to glass windows. LEED certification consists of 69 criteria in six categories ranging from energy use and emissions to water use, material and resource use, and the sustainability of the building site. The focus of the standards is the efficiency of building energy use, which averages 30 percent less in LEED certified buildings. The growth in demand for green building design is having a bandwagon effect on the number of architects, builders, and investors who have come to understand that it is no longer the goal of good design to simply create a building that is aesthetically pleasing. They realize that buildings must become environmentally responsive as well. Many have responded by specifying higher-efficiency lighting, thermally efficient glazing, and increased use of recycled building materials, gray water treatment, and the use of on-site renewable power generation.
