3479 -- ASHRAE Standard 90.2 Envelope Criteria Optimization Technique PDF

Describes an economic optimisation technique that can be used to identify optimum energy conservation options. States the technique is very general. It can be used to define envelope, HVAC equipment, or water-heating equipment optimums. It can be applied to any type of housing. States that the most important feature of this technique is that it provides a consistent procedure that can be applied to all envelope components. It assesses logically all combinations and selects the optimum that satisfies a specific economic criterion. This ensures that all envelope components are treated equitably.
