To improve building energy efficiency, the Hong Kong Government formulated a Buildings Energy Efficiency Ordinance (建築物能源效益條例) [2] which was passed by the Legislative Council in November 2010. Under the Ordinance, certain prescribed types of buildings have to comply with Building Energy Code (BEC) and/or Energy Audit Code (EAC ...
A water audit (domestic/household), similar to an energy audit, is the method of quantifying all the flows of water in a system to understand its usage, reduce losses and improve water conservation. It can be performed on a large scale for a city or a state as well on a smaller scale for irrigation projects, industries, and buildings. The audit ...
