cept university: Cool Legacy: Temp Cut By 4-5°c At Cept | Ahmedabad News
Contemporary to architectural marvels such as IIM-A and the ATMA House, the building has been restored over the two years of the pandemic and is once again open to students.
April 18 is celebrated as the International Day for Monuments and Sites; this year’s theme is “heritage and climate”.
Restaurant owners said they faced several challenges, including one related to the intense heat in Ahmedabad.
With the ecosystem of industrial fans and roof vents coupled with tinted windows, they were able to reduce the interior temperature by 4 to 5 degrees Celsius. The city is already reeling from the searing heat this summer, with the mercury not dipping below 40 degrees for more than a fortnight.
Professor Jigna Desai, head of the Center for Heritage Conservation (CHC) and director of the master’s program in conservation and regeneration at Cept University, said a masterpiece by Doshi, the building offered the both challenges and opportunities. “As a center teaching conscious conservation, it was also a project for us to show how to do it right,” Prof Desai said. “While there are many ways to do this, we mainly focused on material integrity, longevity and stability as the deciding factors.”
Cooling and ventilation were major issues for the team. “While air conditioning might have been one of the answers, it would have compromised the integrity of the structure,” Prof Desai said. “We didn’t want to cover the double-height areas with glass partitions. Other cooling methods were either impractical or expensive.
So the team installed 15-foot-diameter industrial fans instead of conventional fans and also installed nearby roof exhausts.
So, with the speed of the fans, the exhausts working in tandem can move a large volume of air from the interior, providing cooler interiors.
The restorers also replaced the glass in the skylight on the north side of the building. Instead of operable single-glazed windows, they installed double-glazed insulated windows to reduce heat gain.
“The minor changes go with the general theme of the building envisioned as ‘industrial architecture,'” Prof Desai said. “They will ensure the longevity of the building and provide easily replicable means for similar buildings from this era to be restored economically and efficiently.”
