New Children’s Hospital Energy Audit and Detailed Feasibility
Study
Client: AGL
Date: 1999 – 2000
The New Children’s Hospital at Westmead in Sydney is a modern
89,000 m2 facility with 350 beds. The hospital provides a
full range of children’s health services.
In 2000, Exergy completed an investment grade energy audit of the
Hospital on behalf of AGL. The audit was completed as part
of an energy performance contract between AGL and the Hospital.
Exergy identified and investigated a number of opportunities to
reduce energy consumption and costs, including:
- Air conditioning system recommissioning;
- Improved cooling tower controls;
- Lighting system upgrade;
- Domestic hot water upgrade, including the installation of solar
hot water; and
- Power factor correction.
Total savings opportunities identified by Exergy amounted to almost
16% of the site energy use, with an average payback of less than
3 years. Exergy also completed a study into the engineering
and financial feasibility of each energy savings measure.
Exergy maintains an ongoing advisory and monitoring role in the
project.
