According to a study conducted by The Energy Research Institute (TERI) proper urban planning can save new urban layouts from becoming heat islands. Today urban layouts are prepared without considering their impact on heat generation. This can be prevented if roads and buildings are properly aligned.

The research report has found that lower building height and aligning streets against the sun’s path could prevent new layouts from heating up. Narrow roads flanked by buildings on either side with little or no open spaces trap heat resulting in warm surroundings. It is suggested that height of buildings should be decided keeping in mind the width of the road. The report also suggests that lower building height and aligning streets against the sun’s path could prevent the locality from heating up. These suggestions are basically meant for new localities which come up in and around the existing cities and towns.

The report says that roads should not be aligned in the direction of the path of the sun. It suggests the alignment of the road in a North-South direction, rather than an East-West direction. When the roads are aligned in East-West direction they would keep receiving direct solar radiation throughout the day. On the other hand, when roads are aligned in North-South direction they would be mostly covered by buildings which protect them from direct sun rays.

TERI conducted a study which was commissioned by Environmental Management & Policy Research Institute (EMPRI). EMPRI is an autonomous institution conducting applied research on environmental issues and providing training and advisory services to government, industry and civil society. The institute is anchored at Department of Forest, Ecology & Environment and headed by the Director General appointed by Government of Karnataka.
