A new standard for the design of high-performance green buildings is set to revolutionize the building industry. Published by ASHRAE in conjunction with IES and the U.S. Green Building Council, Standard 189.1, Standard for the Design of High-Performance, Green Buildings Except Low-Rise Residential Buildings, is the first code-intended commercial green building standard in the United [...]

Home theaters are a popular addition to many homes, according to the Consumer Electronics Association, which estimated that by the end of 2004, one-third of U.S. households owned a home theater system, up from about one-fifth at the end of 1999. The addition of a home theater creates special demands on the lighting and controls. [...]

Green construction codes and standards are beginning to emerge on the national code stage. The standards go beyond energy standards such as 90.1 and the International Energy Conservation Code (IECC) to cover additional areas such as site sustainability, water efficiency, indoor environmental quality and materials and resources. This is the subject of a new whitepaper [...]
