To make radical and on-going reductions in energy use, Auckland District Health Board (ADHB) has collaborated with the Energy Efficiency Conservation Authority (EECA) to develop ‘Energy 50/50’, a new energy policy.
The target is to reduce energy use by 50% and produce 50% of energy requirements through on-site renewable energy by 2030. The plan covers all building energy use, including Auckland City Hospital, Starship Children’s Hospital and Greenlane Clinical Centre. This includes electricity and gas, and predominant energy outputs of heat in the form of hot water, steam and cooling.
For this vision to be fulfilled, sustained focus, significant resources and investment over a number of years are required. It will provide the opportunity to introduce innovation and new technology.
Reductions in annual electricity and gas usage will be measured against the 2015/16 financial year baseline. So far, since 2015 energy efficiency has contributed to a 36% reduction in certified carbon emissions. In the past three years, 6.9 million kWh energy savings have been achieved.
