Energy efficiency is central to most definitions of high-performance buildings. It is also central to BSC’s consulting, research, and education activities. At BSC, we believe in promoting energy efficiency and environmental responsibility within the constraints of marketable and affordable building technology.
The documents below discuss why energy is critical to sustainability and how to define and understand energy use (for example, through energy metrics). They also touch on key issues in energy reduction in buildings, such as thermal control and advances in window technology for commercial and residential buildings.
The American Foursquare, a Sears, Roebuck & Co. kit home, was a staple of small American towns between 1908 and 1940. More than 100,000 of them were built in America. Homes built prior to 1980 make up 80% of the housing stock in the United States, and are responsible for a majority of the residential energy use in the country. All of the renovations used systems engineering principles to ensure good indoor air quality and longterm durability while providing deep energy reductions. This posting is permission of ASHRAE.

This paper was first presented at the 2011 ASHRAE Annual Conference. A startup builder in the San Francisco Bay Area has a goal of producing factory built/modular houses with net zero energy performance. Their first prototype was a two-story, two bedroom, urban infill townhouse design. It has been in operation for roughly a year, and has been extensively measured and monitored, providing information about its net zero performance.
