• LIGHTING THE PATH TO ENERGY EFFICIENCY CHANGES PROPOSED FOR STANDARD 90.1 |
|
|
Nine addenda are proposed to ANSI/ASHRAE/IESNA Standard 90.1-2007, Energy Standard for Buildings Except Low-Rise Residential Buildings. The addenda are currently open for public review. Proposed addenda would establish revised lighting power densities for both whole building and space-by-space compliance methods. The addenda would reduce lighting power allowances in many building and space types, while maintaining industry-recommended lighting levels as their basis. Additional proposed day lighting control requirements will also encourage the incorporation of effective day lighting and corresponding electric lighting control into designs.
