The U.S. Green Building Council and Ember Strategies recently released the results of a deep dive study into the design energy efficiency of a decade of LEED buildings (PDF). Ten years of LEED data shows the evolution of the best in the architecture, engineering and construction industry — and a few industry quirks — as they strive for more efficient building designs.
Buildings are certified at varying levels in the Leadership in Energy and Environmental Design standard — from basic Certified to Silver, Gold, and Platinum — based on the number of points they earn across the categories of green building, such as energy, water, indoor environment, location and materials. Having a LEED certification is one way commercial real estate owners prove their building is one of the best in the world as they work to attract tenants. This study looked at the New Construction rating system for building design and construction and specifically certain energy efficiency related credits.
Before digging in to the data, it is important to understand that a LEED rating system is born, grows and eventually dies and is replaced by a new rating system. This is unlike a building code or standard. The LEED rating system is tweaked in each version to raise the bar for achievement, of course, but also to try to fix credits that just aren’t working. If no one achieves a credit, there is no environmental benefit to having it. USGBC uses feedback from the market to improve the rating system over time.
The study was released at the ACEEE’s 2014 Summer Study on Energy Efficiency in Buildings, the biennial gathering of building efficiency nerds in Pacific Grove, Calif.
