Trade-off Calculations for Above-ground Building Envelope Assemblies
Description or Identification of Building Envelope Assembly		Opaque Portions			Fenestration Portions			Area of Assembly in Reference Building: Air, (m²)	Area of Assembly in Proposed Building: Aip, (m²)	Minimum Allowable Thermal Resistance of Assembly in Reference Building (prescriptive values): Rir (m²•K)/W		Thermal Resistance of Assembly in Proposed Building: Rip (m²•K)/W		Air / Rir (W/K)	Aip / Rip (W/K)
		Wall	Roof	Floor	Fenestration	Door	Skylight
Fenestration Trade offs are limited to fenestration on the same elevation. Please indicate which elevation contains the fenestration being calculated										North South East West

TOTALS:
Is building envelope compliant with simple trade-off path? (Aip / Rip < total Air / Rir and Aip = Air )
YES
