Innovation and Design Credit 1.3 Design Charrette (1 Point)

Thermal Roof Systems ccSPF will impact the design of a home?s HVAC system. With the superior insulation R-values, conditioned attic system and reduced air infiltration provided by Thermal Roof Systems ccSPF, it may be possible to reduce the HCAC sizing. This reduced size in the HVAC unit may offset the initial cost of the superior Thermal Roof Systems ccSPF.

Innovation and Design Credit 2.1 Durability Planning (Prerequisite)

Thermal Roof Systems ccSPF will contribute to durability measures for:

  1. Air Infiltration- Thermal Roof Systems ccSPF exceeds ASTM E283 @ 75Pa air leakage rates resulting in significantly reduced air leakage.
  2. Interstitial Condensation- Thermal Roof Systems ccSPF has a water vapor transmission of <1 @ 2 inches ASTM E096, thus preventing condensation between the insulation and sheathing of the roof and walls.
  3. Heat Loss- Thermal Roof Systems ccSPF has the highest R-value, 6.5 per inch, of any insulation material. Innovation and Design Credit 2.4 Third Party Durability Management Verification (3 points) Third party inspections of Thermal Roof Systems ccSPF installation can support the durability management verification points.

Energy and Atmosphere 1 Optimize Energy Performance (1-34 potential points)
These points may be received using either the Performance Path for Energy Star homes or the Prescriptive Path.

Performance Path

Thermal Roof Systems ccSPF may improve the energy efficiency and the HERS score as follows:

  1. With an R-6.5 value per inch, Thermal Roof Systems ccSPF can achieve higher insulation values (Up to R-23) in typical 2×4 wall framing cavities.
  2. Thermal Roof Systems ccSPF eliminates voids and compressions in wall cavities, allowing it to receive the HERS Grade 1 installation quality rating.
  3. The Thermal Roof Systems ccSPF conditioned attic application (bringing the attic into the building envelope) will reduce the load on the HVAC unit when the HVAC unit is placed in the attic.
  4. Thermal Roof Systems ccSPF provides a complete air barrier, reducing air infiltration into the home. This allows for a possible reduction in HVAC sizing.
