ARE HIGH PERFORMANCE BUILDINGS REALLY PERFORMING?
It is possible today, at an incremental construction cost of 2-10%, to create buildings which operate at 25, 50, and even 75% less energy than Standard 90.1-2004. A few high profile buildings touted to be designed as low-energy have been extensively metered and studied. This presentation provides an overview of the process, performance, technologies, and lessons learned for these recent ‘high performance’ buildings which range in measured energy savings of 25-70% over Standard 90.1 and opportunities for even greater savings in the future—achieving cost-effective net-zero energy commercial buildings by 2025.
