What does it take to meet the ASHRAE 90.1 2004 standard?
ASHRAE 90.1 applies to several building components—the building envelope; heating, ventilating and air conditioning systems; water heating; and power, lighting and other equipment. Individual requirements in the standard, such as wall insulation, may differ depending on the climatic zone in which the building is located. Compliance with the standard can be achieved either by meeting prescriptive requirements or by using computer software to model the building and determine how to achieve a particular energy performance target. Trade-offs among different building components may be used to achieve the target. The building project architect and engineers will develop a design that conforms to the ASHRAE standard.
