Green Building Research

Enwave Seattle is a District Energy system, and District Energy is recognized worldwide as an eco-friendly, high-performance way to heat buildings.

Buildings on the Enwave Seattle system — whether new or old — are part of the new green economy. By using District Energy, buildings earn points toward certification under the Leadership in Energy and Environmental Design (LEED 3.0) program or the EPA's ENERGY STAR program, as well as benefit from the growing market demand for green commercial space. Several recent studies find that "green" commercial buildings offer the best long-term investment value:

Energy Performance of LEED for New Construction
New Buildings Institute, March 2009
This study found that on average, LEED-NC buildings deliver anticipated savings. LEED energy use is similar to predictions — 25-30 percent better than the national average.

Results for individual buildings span a wide range, which calls for further research and areas of improvement for LEED.
