Original research undertaken by Cardiff University has now been updated by Energy Equipment Testing Services Ltd (PV Systems) who were recently commissioned by coatings specialists W H Screeton Associates Ltd to analyse the contribution their robust solar reflective coating Retroflect can have on the reduced production of carbon dioxide emissions at the primary source of energy production.
The research followed field trials using Screeton's Retroflect in California and the Caribbean. which showed both large scale decreases in C02 emissions and major savings on energy costs.
The use of Retroflect on the bituminous roof of a bungalow in San Diego, California reduced cooling loads by 60% and resulted in a decrease in the amount of C02 released into the atmosphere of 0.47kg for every kWh (Kilowatt Hours) - 750 kgs a year.
The trials on the Caribbean island of Bequia comprised applying Retroflect to bituminous shingles and a metal roof which reduced inside temperatures from 41 c to 29,5c when the ambient temperature was 33c thus providing economic passive air conditioning with minimal cost and at the same time reducing potential C02 emissions.
