The previous version of this note (Energy Efficiency in Commercial Buildings by Deo Prasad May 1995) emphasised the need for including fundamental concepts of energy efficiency such as climatically suitable designs and forms, benefits of tailored building facades and envelopes for day lighting and sun control, inclusion of thermal mass, an efficient management and operational plan and significance of alternative energy sources.
This note revisits the scope for energy efficiency in commercial buildings and discusses some emerging technologies and trends in thinking.
