ASHRAE Releases 90.1-2010–Part 1: Design, Scope, Administrative Requirements

ASHRAE/IES 90.1, Energy Standard for Buildings Except Low-Rise Residential Buildings is published every three years to provide states and other jurisdictions with a model commercial building energy code.

The 2010 version, published November 2010, represents the most dramatic revision of the standard since 1999. Over the past decade, the standard has steadily become more restrictive in terms of allowed lighting power and requirements to install lighting controls. The 2010 version takes both of these trends to a new level with the goal of achieving dramatic energy savings and taking a significant step towards the ultimate goal of net-zero buildings. In all, the new ASHRAE/IES 90.1 standard is far more comprehensive, stringent and complicated than its predecessors.

In this two-part series of special reports by the Lighting Controls Association, we will examine the new energy standard in detail. Part one, presented here, focuses on changes to the prescriptive lighting power requirements as well as changes to scope and administrative requirements. Part two, to be published next month, will focus on the standard’s extensive list of new mandatory and optional lighting control requirements.
