Revised ANSI/ASHRAE Standard 105-2014 compares building energy performance

April 8, 2014 - The newly revised ANSI/ASHRAE Standard 105-2014, Standard Methods of Determining, Expressing, and Comparing Building Energy Performance and Greenhouse Gas Emissions, provides a consistent method of measuring, expressing and comparing the energy performance of buildings, says ASHRAE. It also provides a common basis for reporting building energy use in terms of delivered energy forms and expressions of energy performance; for comparing design options; and for comparing energy performance in terms of energy resources used and greenhouse gas emissions created, both across buildings and for energy efficiency measures within buildings, it adds. According to Keith Emerson, chair of the Standard 105 committee, the new edition includes procedures for going beyond site energy to calculate the impact of building energy use on primary (source) energy and greenhouse gasses. The standard is now available at www.ashrae.org/bookstore.
