Part of 2008 Energy Extension & Improvement Act Applies to new or existing buildings Available through 2013 A total $1.80 tax deduction may be divided between partial deductions for: –Lighting systems: $0.60 / sq. ft. –Heating & cooling systems: $0.60 / sq. ft. –Building envelope: $0.60 / sq. ft. The deduction is available for private and public projects: –Private Project: The building owner may receive the deduction –Public Project: The building designer may receive the deduction (1) High R Roofs Commercial Building Tax Deduction (1) IRS Notice

Building Envelope Partial Tax Deduction How the Building Envelope Deduction Works A $0.60 per square foot deduction is available for building envelope improvements only: Roof, walls, doors, windows In order to qualify, the building envelope must be upgraded to provide a minimum 20% reduction over ASHRAE in the combined usage of the building’s heating, cooling, ventilation, hot water, and interior lighting systems (1) Energy calculations must be performed and certified by a design professional using approved energy software (2) The deduction must be taken in the year the building or the energy improvement is placed in service Roof insulation and reflective roof surfaces may be used in part to achieve the 20% reduction (1)IRS Notice (2)List of approved software available at

Recommend “LEED-equivalent” R-values that achieve LEED savings targets for customers looking to “go green” Provide an energy analysis with every roofing quote using the NRCA “EnergyWise” Online Roof Calculator Look for local partners to develop building envelope solutions eligible for the Commercial Building Tax Deduction High R Roofs High R Business Strategies
