John Hunter Hospital – Preliminary Study
Date: 2002
Client: AGL
John Hunter Hospital is the primary hospital serving the city of
Newcastle, north of Sydney, NSW. Built in the late 1980’s,
it is a modern 65,000m2 facility covering all aspects of hospital
services.
Exergy was commissioned to conduct a preliminary investigation
of the site on behalf of AGL. Our investigations revealed
a site that had many common technical problems under control, but
where the air conditioning plant was generally oversized.
We identified that it would be feasible to address many of the oversizing
problems through simple measures, such as changing fan speeds and
introducing variable speed controls. Opportunities for gas
savings through improved boiler load management were identified,
and lighting improvements were also identified. Total
estimated savings were of the order of 10%.

This is the three-storey primary accessway through the middle of
the site. Air-conditioning this large atrium is an issue in
itself!
