A Parametric Study on Exterior Insulation Systems and Heat Reflective Paints for Energy Efficiency in Buildings

Abstract:

Buildings are responsible for at least 40% of the used energy in most of the countries and the figure is rising as the construction booms. But pace of energy saving in building is much lower in India as compared to developed countries. So, there is an immediate need to open up new techniques to address the issue and also progress in the area of actual implementation should be accelerated immediately because both knowledge and techniques are available today to slash the energy usage in a building.Our focus is mainly on the modification of building envelope to reduce the energy used for cooling in A/C building and to reduce the temperature of the interior of non-A/C building.Berger has developed different systems such as EIFS for wall, Roof insulation and Heat reflecting paint for both wall & roof. The efficiency of these systems in terms of energy saving and cooling has been tested at Howrah and also has been tested by CBRI at Roorkee, through actual field study for two years. The test results revealed that the maximum energy saving of 32.33% can be achieved for A/C building. For non A/C building, maximum temperature difference of 6.4°C between outdoor and indoor air of the room can be achieved.
