Why High R Roofs? Economical Investment During Re-Roofing Long-Term Building Energy Savings Greenhouse Gas Reduction Federal Tax Incentives
5
“Old” Standard: ASHRAE 90.1-1999 to 2004 “New” Standard: ASHRAE 90.1-2007 “Future” Standard: ASHRAE 189.1-P High R Roofs Insulation Standards

High R Roofs LEED: The Future is Now The most recent version of LEED requires a minimum of 8% up to a maximum of 48% total building energy savings over ASHRAE 90.1-2007 For the roof to contribute its “fair share” to the energy savings, R-values must be increased above ASHRAE 90.1-2007 minimums

High R Roofs Calculating the Savings Use the NRCA “EnergyWise” Online Roof Calculator http://energywise.specright.net/
11
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 2008-40
12
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 90.1-2001 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 2008-40 (2)List of approved software available at http://www.eere.energy.gov/buildings/info/tax_incentives.html
13
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
