Impact of internal and external factors in building energy consumption in Sri Lanka

Abstract

This research describes work that covered both theoretical and practical aspects of impact of internal and external factors in building energy consumption. It gives a brief introduction of various concepts related to psychometric and cooling load of air conditioning system which is useful for an energy optimization in building. Various mathematical and graphical models were developed to assess the impacts and implementation issues. An economic analysis was also carried out to help prospective users on energy savings ideas. In addition to the direct financial savings on energy bills, various other indirect benefits to the building and environment such as extended life time of air conditioning unit reduced emission and pollution, fewer burdens on the national utility grid etc.
