FAQ F-00172
Can translucent roof sheeting be excluded from credit 25.0 Heat Island Effect Reduction?

Yes, conditionally. 

Translucent polycarbonate roof sheeting can be excluded from the calculation of site area percentages under credit 25.0 Heat Island Effect Reduction. The surface area in plan view covered by translucent roof sheeting may be subtracted from the total site area of the project for both the compliant and non-compliant areas. This is on the following condition(s):

  • The translucent roof area is to comprise no more than 20% of the overall roof area. 
  • At least 75% of the remaining site area must meet the compliance requirements in order for this credit to be claimed. 
  • The project team must demonstrate how the translucent roof sheeting has other flow-on sustainability benefits that make it equivalent to Solar Hot Water and Photovoltaic Panels.
