Energy Efficient Buildings

Energy efficiency of buildings is monitored using sensor technology in order to develop accurate models for next generation buildings. Sensors are placed at critical locations to collect information about the temperature, humidity and CO2 levels. With the help of external weather station the heating/cooling of such buildings can be optimised to give best or preferred performance.

Hygrothermal performance of building materials are analysed using sensor based monitoring in both laboratory and on site. The models are further calibrated to determine the long term performance of such materials and also the effect of this combined action on ‌al loss in buildings.

Optimised Retrofitting for existing buildings: With 100s of retrofitting options available in the market, the research here is focused on identifying the best options for optimum performance. Long term performance and durability of the building materials are given high importance along with the environmental impact of the materials used in retrofitting. We are in the process of developing a retrofit decision making tool for helping users with their choice. The research is making progress in minimising the gap between predicted and actual performance of buildings.
