Draught includer

摘要

The Torrent Research Centre in Gandhinagar, Gujarat's new political capital, is an energy miser. It consumes around 54kWh per square metre, compared to an Indian average for new buildings of 280-500kWh. It's similarly miserly when it comes to carbon emissions, accounting for just 72kg per square metre (compared to an average 380-670kg per square metre). The key is passive solar design, which drastically reduces the need for both conventional air conditioning and artificial light. By using passive downdraught evaporative cooling, it brings indoor temperatures close to bearable even on the hottest summer days.
