Sustainable Preservation Coalition
The National Trust for Historic Preservation created the Sustainable Preservation Coalition two years ago in order to impact further development of the LEED (Leadership in Energy & Environmental Design) Building Rating Systems. We partnered with several national organizations who were developing separate sustainability agendas including the AIA, APT International, the National Park Service, General Services Administration and the National Conference of State Historic Preservation Officers. We realized we could make a bigger impact integrating historic preservation and green building values by working together.
Our first goal was to meet with the U.S. Green Building Council, the developer of LEED, and open up a dialogue to discuss improvements to their products which would better reflect the importance of existing buildings to sustainable stewardship of our planet and its limited resources. While LEED does much to encourage more sustainable development, and historic buildings can achieve the highest LEED rating, we believed it could certainly do better because the current version of LEED (LEED 2.2):
1. Overlooks the impact of projects on cultural value;
2. Does not effectively consider the performance, longer service lives and embodied energy of historic materials and assemblies;
3. And is overly focused on current or future technologies, neglecting how past experience helps to determine sustainable performance.
Our meeting with the President of USGBC (Rick Fedrizzi) and the Director of LEED Technical Development (Brendan Owens) was quite successful, ending with Rick inviting us to help them prepare preservation metrics for the revised versions of LEED. Over the past year, our coalition has been meeting with USGBC and are delighted to announce that soon LEED 3.0 will be unveiled.
