Retrofitting The Atrium Of CST Adm Building: To Achieve Optimum Thermal Comfort.

Energy efficiency and renewable energy have become the twin towers of sustainable development and this ultimate goal can be achieved only if the energy conservation at all levels is efficiently practiced. Energy consumption is the world’s growing concern with building sector topping the energy consumers list. The buildings with its HVAC (Heating Ventilation & Air Conditioning) components and other mechanical system have become one of the world’s largest energy consumers. The building envelope evolution have shown that the wider scope of façade system and glazing options, have further led to solar responsive challenges & massive energy loss. In College of Science & Technology, there are many active means of cooling installed at every corner of the building due to its location and extreme summer heat. Atrium at the east-front of ADM building have necessarily failed in regulating diurnal temperature due to its extensive glazing ratios and areas exposed to the direct sun rays. This research is an attempt to intervene the space: at structure as well as material level to maximize its thermal comfort during daytime through a simulation approach.
