Heating, ventilation and air conditioning (HVAC) guide

Heating, ventilation and air-conditioning (HVAC) are major contributors to a business’s energy use and operating costs.

HVAC optimisation looks for the best ways of using existing systems, rather than opting for large-scale equipment upgrades and replacements.

Optimisation can be done by:

  • changing algorithms
  • altering control schedules and set points
  • carrying out minor mechanical repairs and alterations.

 

 

This guide outlines 20 HVAC optimisation strategies and how they can be applied to most commercial systems in older and modern buildings.

For a simple summary of the technology:

 

HVAC optimisation will reduce your energy bills

By taking action you could save up to 50% of your total HVAC energy use, or up to 80% of energy use in individual HVAC systems. In many instances, optimisation can provide immediate reductions in energy usage and costs.

Other benefits can include:

  • more comfort for a building’s occupants
  • improved reliability of systems
  • reduced maintenance costs
  • improved building performance, as recognised in rating schemes such as National Australian Built Environment Rating System (NABERS) and Green Star.
