46 Cool roofs and peak demand Demand savings of about 0.25 kw per 100 m 2 Down-sizing of AC systems Most building systems are designed based on summer load Cool roofs allows downsizing of system A downsized systems runs more efficiently, even in winter In transitional climates, cool roofs (along with other measures) may eliminate need for AC Source: Akbari and Konopacki, Energy Policy, Levinson et al.

53 Pointers Winter penalties are small Anywhere that cooling is required, a cool roof saves $ Consider installing cool roof first, then AC Cool roofs, cool the globe, reduce heat islands, reduce urban smog, and may last longer Cool roofs reduce the effect of heat storms; save life Remember for many applications, cool roofs do not incur any incremental cost 53
54 100m 2 of a white roof, replacing a dark roof, offset 25 tonnes of CO 2 emissions Akbari et al Environ. Res. Lett 54
55 White low-sloped roofs for AC buildings Annual AC savings of ~ $/m 2 ; 5-10 kwh/m 2 Annual CO 2 savings of kg/m 2 CO 2 savings over 20 years life of roof kg/m 2 NPV of 20 years AC savings of ~ $/m 2 Maximum incremental cost for most roofs 2.5 $/m 2 A no brainer 55
56 Cool-colored steep-sloped roofs for AC buildings Annual AC savings of ~ $/m 2 ; 3-5 kwh/m 2 Annual CO 2 savings of kg/m 2 CO 2 savings over 20 years life of roof kg/m 2 NPV of 20 years AC savings of ~ $/m 2 Maximum incremental cost for most roofs 2.5 $/m 2 Go for it 56
57 White low-sloped roofs for non-ac buildings Global cooling offset: 250 kg/m 2 Current value of CO 2 offset: 25 $/tonne Global cooling value of white roofs: 6.2 $/m 2 Incremental cost for most roofs: $/m 2 Give 2.5 $/m 2 rebate every 10 years Save the remainder 3.7 $/m 2 ; see it grow to 6.2 $/m 2 in 10 years Does it work? 57
