The challenge
Improving energy efficiency of buildings
Buildings are responsible for more than one-third of global energy-related greenhouse gas emissions.
According to the Intergovernmental Panel on Climate Change, the most cost-effective way to achieve emission reductions is by making improvements in buildings.
Our response
Developing smart management systems
The CSIRO developed OptiCOOL, a system that alters the operation of a building's heating, ventilation and air conditioning (HVAC) control system intelligently, to provide cost savings, occupant comfort and energy efficiency.
The OptiCOOL technology, commercialised as BuildingIQ, takes feedback from occupants — whether they are too hot or too cold — submitted online. This feedback plus weather data and energy market pricing is used by the intelligent air-conditioning controller to alter the operation of the building's air-conditioning to:
- reduce energy consumption
- reduce greenhouse gas emissions
- save money
- improve comfort for occupants.
The controller can be fitted onto any existing HVAC control system.
The results
Installation in iconic buildings
BuildingIQ is helping building owners across Australia and the United States to reduce their energy consumption by 12 to 30 per cent.
Argonne National Laboratory (United States) independently tested BuildingIQ and found that the system reduced HVAC energy consumption by up to 45 per cent.
The CSIRO Energy Centre in Newcastle has achieved energy savings of up to 30 per cent using this technology. It is also being used at the Rockefeller Center in New York in the United States.
Australian start-up BuildingIQ commercialised the technology in 2009. Four years later, they announced $9m in venture funding, accelerating the technology's uptake.
BuildingIQ is now working in all sorts of commercial properties, from education facilities and government buildings, to hospitals and hotels.
