Investing in Energy Efficiency Pays
By Preston Koerner on October 28, 2009
The Center for Neighborhood Technology (CNT) conducted a post-occupancy study of 25 LEED commercial projects in Illinois and just published the first round of results from their research. The Regional Green Building Case Study Project is one of the first post-occupancy studies to measure energy performance, greenhouse gases emissions, water use, transportation effects, construction and occupancy costs, health benefits, and occupancy comfort on a regional scale. Although CNT found that some LEED projects perform better than others, they also determined that investing in energy efficiency pays off.
More specifically, CNT found that LEED projects that obtained a higher number of EA Credit 1 points performed better than those that didn't. In other words, projects that prioritized energy performance performed better than those that don't or than those that focused on other aspects of LEED certification.
