OBJECTIVE
Reduce energy use and emissions through optimised temperature settings for heating/cooling.
IMPACT
Low
HVAC usually accounts for approximately 40% of energy. Every degree increased for heating, and reduced for cooling, can lead to between 5% and 10% efficiency improvements.

Heating, ventilation, and air conditioning (HVAC) is the use of various technologies to control the temperature, humidity, and purity of the air in an enclosed space.

The goal of HVAC is to provide thermal comfort and acceptable indoor air quality. Energy consumption and associated emissions can be reduced through optimising temperature settings for heating/cooling.

Automated temperature settings for maximum energy efficiency are:

Heating optimal temperature range: 18-20⁰C
Cooling optimal temperature range: 25-27⁰C

Council's facilities with higher energy consumption and usage, as determined by facility assessments, will be targeted first.

Tasks

What's left to do?

30/06/2024
Review HVAC programming of buildings and facilities
Review HVAC programming of facilities - who is responsible, how often is it changed, why are these levels chosen?
31/08/2024
Assess the settings and use of personal heating/cooling devices by staff
Conduct physical audit of work spaces (e.g. heaters under desks).
Conduct staff survey on usage of equipment, thermal comfort, and alternative options for managing temperature.
31/12/2025
Ensure HVAC optimisation is standard practice for new buildings

What are we doing?

30/06/2024
Ensure that HVAC systems are set at maximum energy efficiency levels for heating and cooling.
Automated temperature settings for maximum energy efficiency are:
Heating optimal temperature range: 18-20⁰C
Cooling optimal temperature range: 25-27⁰C
