House built with passive cooling designHeat has become an increasing issue with rising temperatures. Hot summers have forced many to rely on air conditioning, but in turn forcing more power consumption. To alleviate this issue, some researchers have turned to the past to find solutions as member Diya Dwarakanath writes. In some parts of history, especially cultures that lived in large swathes of deserts and other hot regions, the people there had come up with innovative designs for passive cooling to keep their abodes more refreshing than their surroundings. Often, ancient builders used lighter colors in paint to reflect sunlight away from the structure. Another method was to use dense materials in construction. That proved to have much better insulation than many thinner modern counterparts. Find out more about effective ways to cool buildings with Dwarakanath’s piece as they write about these promising researches.
