Four billion square feet of new low-slope roofs are installed each year that can be designed and installed to reduce building energy consumption …

… provided these roofs are designed and installed to accomplish these goals.

Energy Scenarios

• Base Case: ASHRAE 90.1 -1999– The current state (at best)– “Energy Standard for Buildings…”– Roofing “R” values unchanged since 1973

• Scenario 1: ASHRAE 90.1-2007– The future state (if/when adopted by building codes)– 25% average increase in minimum “R” values

• Scenario 2: ASHRAE 189.P (Proposed)– An alternative “green” future– “Standard for the Design of High-Performance Green Buildings…””– Additional 20% average increase in minimum roof “R” values

Annual Savings v. Base Case:

1) Annual energy costs based on 4 billion square feet of total annual roof installations, $0.12 / K WH cooling energy cost, $1.00 / therm heating energy cost, 2.0 cooling COP, and 75% heating efficiency. Assumes 20% of roofs are replacing existing cool roofs, 5% of roofs are installed over unheated spaces, and 20% of roofs are installed over non-cooled spaces. Calculations derived using the EnergyWise Calculator (http://energywise.specright.net) for gross heating and cooling costs and the DOE Cool Roof Calculator (http://www.ornl.gov/sci/roofs+walls/facts/CoolCalcEnergy.htm) for cool roof energy costs.

2) Actual R values vary +/- R5, depending on ASHRAE climatic zone.3) A cool roof is defined as a roof offering 50% long-term solar reflectivity or the thermal equivalent for the service life of the roof.4) Best practices is defined as 2 or more staggered insulation board layers to minimize thermal loss at board joints.
