Case studies

During the design phase of Waitakere Hospital a design audit was undertaken to ensure that the new facilities were low-energy environments. Adjustments were made to the design so that the buildings made the most of natural ventilation, insulation and natural lighting levels were increased as well as the use of other energy efficient technologies.

Otago District Health Board is taking an innovative approach to improving the building services equipment at Dunedin Hospital. It's contracted an external company, Honeywell, to make the improvements.

Honeywell guarantees energy savings of $122,200 a year that will pay for the capital expenditure within five years.

Canterbury District Health Board recognised the Christchurch Hospital energy management team with a Quality and Innovation Award for its strategy that achieved 10% energy savings, worth $180,000 a year.

Carter Holt Harvey Kinleith's five-year plan for efficiency cut energy consumption per tonne of product by 31%. Although production increased by 25%, carbon dioxide emissions stayed stable.
