An integrated approach to energy management and auditing over the past 10 years has turned Australia's Parliament House into an energy champion. Total energy consumption and associated greenhouse gas emissions over that time have been culled by an impressive 52.3% and 41.2% respectively. Equally impressive is the fact that all energy efficiency improvements have been fully funded from energy savings.

In 1991 the UK Audit Commission produced energy performance indicators for hospitals based on the type of care provided. However, an analysis of over I 00 hospitals throughout 1he United Kingdom has found the type of care provided to have relatively little effect on rhe energy performance of hospital . Although other factors influenced energy use to some degree, the major factor affecting performance was found to be the plan of the hospital, as this influenced the amount of mechanical ventilation required.
