1.11.1 Fall Protection
1.12 COOL ROOFS
NOTE: Standards such as LEED® and UFC 1-200-02 promote the use of cool roofing, and increased energy conservation through additional insulation.
Cool roof design shall follow the requirements in UFC 3-110-03 "Roofing" Chapter 1, Cool Roofs.
Consider that when cool roofing is used with insulation R values greater than 24, the 'cool roof' surface has little if no influence on the energy performance of the building. Additionally, designers should be aware of the possible negative impacts of using cool roofing that may result in unintended consequences. Mechanically-fastened single-ply roof systems shall comply with the requirements for mechanically-fastened single-ply systems in UFC 3-110-03 "Roofing", Chapter 2. Condensation on the underside of mechanically-fastened systems can result in ice build-up in winter, mold growth on the facers, moisture dripping into the interior, and replacement of the roofs with less than four years of service. See Appendix B of UFC 3-110-03 for more information. Poor design of cool roofs in ASHRAE climate zones 4 and higher have resulted in the unintended consequence of condensation below the membrane -- a result of the material's inability to warm and drive moisture downward. Roofs that experience this condensation have had to be replaced. Other unintended consequences include the overheating of masonry walls, interior spaces, roof top piping and mechanical equipment as a result of the reflected UV rays.
NOTE: Cool roof design shall follow the requirements in UFC 3-110-03 "Roofing", Appendix B, and ASHRAE 90.1 - SI ASHRAE 90.1 - IP Chapter 5, for the design of insulation and energy performance of the building. Cool roof design for insulation shall meet at a minimum the ASHRAE 90.1 - SI ASHRAE 90.1 - IP Chapter 5 zone requirements. Inadequate design of cool roofs in ASHRAE climate zones 4 and higher have resulted in unintended consequences of
SECTION 07 52 00 Page 24 condensation below the membrane, overheating of masonry walls, interior spaces, roof top piping and mechanical equipment as a result of the reflected UV rays.
NOTE: If a cool roof is selected, meet the ASHRAE
90.1 - SI ASHRAE 90.1 - IP Chapter 5 values for cool roofing. If a cool roof is not selected in zones 1-3, meet one of the exception requirements listed in ASHRAE 90.1 - SI ASHRAE 90.1 - IP Chapter 5 or provide thermal insulation above the deck with an R value of 33 or greater.
[ Meet the ASHRAE 90.1 - SI ASHRAE 90.1 - IP Chapter 5 values for cool roofing. If a cool roof is not selected in zones 1-3, meet one of the exception requirements listed in ASHRAE 90.1 - SI ASHRAE 90.1 - IP Chapter 5 or provide…
