Designing Australian net-zero hospitals
With high continuous energy requirements including heating, ventilation, air conditioning, and 24/7 operations – hospitals are some of the largest energy consumers in most Australian states
Total Australian public hospital energy use was stable for the three years (2016/17 to 2018/19) (Table 1 available in PDF). Renewable energy production/purchase increased from 14/ 4,132 GWh to 94/ 4,122 GWh (from 0.3% to 2.3% of power consumed). Australian renewable grid electricity uptake grew by 8.3% (from 15.7% in 2016/17 to 24% in 2018/19).
Backup power will continue to be provided according to the Australian Health Facility Guidelines, typically via diesel generators. Electrification projects will also consider on-site renewable generation and storage to further strengthen energy security during extreme events.
Victoria and New South Wales combined consumed 60% of total Australian public hospital energy (1,288 and 1,206 of 4,122 GWh respectively, 2018/19). Queensland public hospitals consumed 778/4,122 GWh [19% of total energy] and produced/purchased the most renewable electricity (74/778 GWh [9.5%]) of all state public hospitals in 2018/19.
Allowing for 50% inefficiencies for cloudy days and battery storage, we would need a solar farm at Sydney's latitude of approximately 4 km2 (two km long, by two km wide) to power all of Australia's public hospitals (our calculations).
