While high-performance buildings are the obvious choice in today’s sustainability-focused industry, it was only a short 35 years ago that the first standard for energy efficiency was established, setting the engineering engine of sustainability into motion. This year marks the 35th anniversary of publication of ANSI/ASHRAE/IES Standard 90.1, Energy Standard for Buildings Except Low-Rise Residential Buildings. Since being developed in response to the energy crisis in the 1970s, Standard 90.1 now influences building designs worldwide. It has become the basis for building codes, and the standard for building design and construction throughout the United States.
Since its inception in 1975, Standard 90.1 has been widely adopted as the benchmark for energy efficiency in buildings. It has set the foundation for energy efficiency in buildings in the United States and is expected to continue internationally. Standard 90.1 has been a game changer in the building industry, and there’s no doubt that its influence is even greater today than it was 35 years ago.
In celebration of this milestone, a series of articles on the standard is being republished here. The articles originally appeared in ASHRAE Journal in the March and June issues.
