Commercial buildings

Energy efficient commercial buildings

Building owners, managers and tenants all benefit from an energy efficient building. For building owners and managers, an energy efficient building helps save on base building consumption and costs and boost its commercial value. Tenants benefit from lower energy bills, better climate control and a more comfortable work environment.

Top energy-saving tips


Lighting can account for up to 40 per cent of energy costs in commercial buildings.

Investing in the latest lighting technology can often provide a quick win, with short pay back periods from lower power consumption and reduced maintenance.

Sensors and timers can stop money being wasted lighting areas that are not in use.

Replacing high bay or fluorescent lights with LEDs can achieve up to 70 per cent energy savings on lighting.

Air conditioning

Heating, ventilation and air conditioning (HVAC) can account for up to half your building’s energy costs. Understanding and optimising your HVAC systems can turn into significant cost savings.

Hot water

Energy and cost savings can be achieved by updating and replacing older hot water systems to match the volume and temperature of water for your building's current and likely future needs.

Improved metering and monitoring

Sensors and building management systems are increasingly sophisticated and cost-effective. Improved monitoring, through submeters, means energy wastage can be identified more precisely and addressed. Building management systems can automate shut off times, so equipment is not left running after hours.

How much can you save?


Property development and management company ISPT has slashed energy usage at its Sydney CBD building by an impressive 60 per cent, and in the process added wellbeing benefits to its tenancies.
