Case Studies of Energy Efficient Buildings

This energy efficient buildings case study summarizes a detailed analysis of 22 case studies of high performance buildings in the Pacific Northwest. In addition to the analysis of measured energy savings, estimates of incremental costs and common design features were also assessed. These case studies demonstrate success with deep energy retrofits in existing buildings, or achieving near net zero new construction. In addition to their ultra-low energy characteristics, cases were selected for their resilience to climate change and their replication potential across the Pacific Northwest. General recommendations for moving toward ultra-low energy consumption in the built environment are also included in this bulletin at the end of the document.
