The building construction industry is in the midst of a technology revolution, but changes are slow to propagate across individuals, companies and geographies. Researchers have pointed to several market characteristics as possible causes for the adoption lag; among these are poor project liability assignment, severe demand fluctuations, and the broken agency between building owners and occupants. These factors and others limit project investment and knowledge diffusion.

Building project teams have five primary objectives when designing and constructing space for future occupants. A building must heat, cool, ventilate and light its internal space, and supply hot water. To fulfill these project goals, designers specify building systems, envelopes, and strategies that will meet the occupants’ needs while adapting to the surrounding environment. However, designers do not necessarily make design choices with the most efficient finished building in mind. Even when energy efficiency is a primary objective the decision process may not be entirely unbiased.

This study identifies the need for building design decision support regarding new energy efficient technology with a concentration on building technology implementation challenges and the energy efficient and innovative technologies used by project teams to solve the challenges. LEED certified buildings were examined for the study to determine which technologies were implemented most often and their initial energy saving purpose.
