3M Science is innovating new ways to reduce a building’s temperature without using electricity – how cool is that! 🌡🧐 On this Energy Efficiency Day, we are highlighting 3M™ Passive Radiative Cooling Film (PRCF) that reflects enough solar energy to allow passive radiative cooling to occur during the day. PRCF enables 24/7 supplemental cooling and 10-20% energy savings when integrated with building refrigeration and HVAC systems. It can be applied to other surfaces, such as bus shelter roofs, to cool them at night passively. #3MClimateAction #energyefficiency #energyefficiencyday
