There are only a few compulsory energy efficiency programs aimed at industrial facilities. It is only recently that the EU introduced a Directive aimed at the energy performance of buildings that makes it mandatory to carry out energy audits of large commercial buildings at regular intervals. In that respect, the energy conservation program (ENCON) in Thailand is unique, because it began in the early 1990s and it is still running as a compulsory program for improving energy efficiency gap in industry and large buildings.
Voluntary programs are part of energy polices based on targets and incentives that industry may subscribe to or apply for. There is a number of such schemes around the world, but we will point out just one of them that addresses energy and environmental issues.
