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.
