In the process of evaluating the Thermal Barrier Paint's performance and energy-saving potential, Carrefour Thailand painted half of a warehouse's rooftop. Temperatures were recorded simultaneously on both sides, the result demonstrated a dramatic heat load drop on the side painted. 1.1 Ton of CO2 are offset per year for up to 10 years by this project.

Heat load reduction after coating with
Planet Supra Thermal Barrier Paint
Lopburi (Thailand), January 2010
Project’s total carbon offset
1.1 Ton of CO2 per year for 10 years
Planet Supra is a Carbon Offset product: each 10 cans used reduce CO2 emissions
by 1 Ton per year as certified by Carbon Offset Japan (COJ).

Half of the rooftop was painted in order to simultaneously record temperatures on the
same building. The purpose is to clearly demonstrate Planet Supra’s benefits in
reducing heat load and save on air-conditioning costs before rolling out the solution.
