The American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE) last week released its prototype labeling system for building energy efficiency.
The Building Energy Quotient program, which will be known as Building
EQ, will include both asset and operational ratings for all building
types, except residential. ASHRAE is working with major real estate
developers to implement the label prototype this fall with a widespread
launch of the full program in 2010.
Ron Jarnagin, who chairs the committee developing the label, noted that the market, with its move toward placing a premium on energy-efficient properties, would benefit from a labeling program.
“When potential building tenants and owners have information on the properties they are interested in, they can understand the full cost of their investment and place a value on the energy efficiency of a building,” he said. “ASHRAE’s label will help building owners differentiate their product in a technically sound manner while providing tenants with the tools they need to select energy-efficient spaces.”
The ASHRAE labeling program differs from existing labeling programs in that it focuses solely on energy use. Under the ASHRAE program, new buildings will be eligible to receive an asset rating. An operation rating will be available once the building has at least one year of data on the actual energy use of buildings. Existing buildings would be eligible to receive both an asset and operational rating.
The asset rating provides an assessment of the building based on the components specified in the design and would be based on the results of a building energy model. The operational rating provides information on the actual energy use and is based on a combination of the structure of the building and how it is operated.
