Has COVID-19 lockdown impacted on aged care energy use and demand?
https://orcid.org/0000-0001-8320-1585
Highlights The impacts of COVID lockdown on six aged care communities’ energy and peak demand are studied. The lockdown period was compared with the same period of similar temperature in previous years. The impacts of COVID lockdown varied enormously in different climate regions. Effectiveness and limitations of existing energy KPIs are discussed.
Abstract In late March to April 2020 residential aged care facilities (RAC) in Australia were under COVID-19 lockdown. This paper explores whether the resultant restrictions on entry and exit and elimination of site group activities within RACs impacted on the total electricity use, peak demand and electrical load profiles. Six RACs in four different climate zones are analysed, comparing historical electricity load and demand profiles with the lockdown period. The facilities in warm regions showed largest reductions in energy use and peak demands. There was a peak demand timing shift in temperate regions and hot regions’ changes were negligible for energy use or peak demands. This study revealed the limitations of using aggregate data as the key performance indicator (KPI) – energy use per bed. Also, KPIs in relation to cooling degree days (or total cooling and heating degree days) have been examined and are not recommended for temperate regions or temperate seasons. The potential CO2 emission reduction from onsite renewable generation is quantified. Further research is to investigate energy use changes at circuit levels under lockdowns, and develop more nuanced KPIs that include the rate of energy use and the timing of that use.
