COOL EXTERNAL SURFACES
When the temperature is soaring outside, we rely on air conditioners to cool the interiors. But there are simple ways to reduce the temperature of the home by a couple of degrees. This involves installing shades over windows/doors to stop solar radiation from entering the building during summers (remove them to allow warming in winters). This natural way of preventing overheating during summers and warming the house in winters helps reduce power consumption by ACs and heaters. Double glazed windows with air gaps can substantially reduce indoor heating too. Also, heat reflective paints are capable or reflecting 70-80 per cent of the sun’s rays. Apply on the external walls and the rooftop. Lastly, insulation can be added to walls and roofs to reduce heat transfer.
