A paper presented by Professor John Bell from the Queensland University of Technology, Centre for the Built Environment and Engineering Research, made the following observations regarding the technology of SkyCool:
"SkyCool exhibits very high solar reflectance (above 85%) and thermal emittance over 94% and is a practical adherent painting mix with high pigment levels that can expand and contract without delamination. Granqvist and Eriksson reviewed the long history of the field of radiative cooling over a decade ago, with both paints and pigmented foils being studied. TiO2 and ZnS pigments have both been used with partial success, but achievement of the combination of properties exhibited by SkyCool on large areas has been elusive."
Professor Bell further remarked:
"Modelling of whole buildings has also been undertaken to assess the impacts on energy use, greenhouse gas emissions, and operating cost of the building when the coating is applied to the roof. The results indicate that for appropriate buildings, the use of this type of coating can lead to triple-bottom line benefits, with reduced operating costs, reduced environmental impacts, and improved indoor environment."
Following the detailed scientific and engineering details, Professor Bell concluded:
"The benefits of this type of cooling (SkyCool) on building energy use, and internal comfort (which results from both reduced airconditioning and lower roof temperatures), can be substantial. Clearly this type of coating works most effectively where the building has a large floor plate and is low rise, so the maximum benefit from cooling via the roof is possible. Under these circumstances significant savings in operating energy costs and also potential reductions in plant size, and peak energy demand are added benefits."
