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

• 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)

Commercial Building Tax Deduction

(1) IRS Notice 2008-40

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

• 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

Calculating Energy Savings

• For Constant Electricity Rates:– Use the DOE Cool Roof Calculator– http://www.ornl.gov/sci/roofs+walls/facts/CoolCalcEnergy.htm

• For Peak Electricity Rates:– Use the DOE Cool Peak Calculator– http://www.ornl.gov/sci/roofs+walls/facts/CoolCalcPeak.htm

Important Note: Consider using an aged reflectivity value (approximately 50%) not to overstate long-term energy savings.
