New CSIRO developed smart software will be trialled by Lend Lease Core Plus Fund (LLCPF) to reduce energy usage in four of its commercial assets by up to 30 per cent.

LLCPF will install the software for an initial period to target energy savings, improve tenant comfort and cut greenhouse has emissions.

Called BuildingIQ, the software uses technology to optimise how a building's heating and air conditioning system operates and also incorporates weather updates to maximise air conditioning and energy efficiency.

BuildingIQ can also help to cut operating expenses and improve a building's official National Australian Built Environment Rating System (NABERS) star rating.

Lend Lease's Asia Pacific head of sustainability says "We particularly like that the BuildingIQ system can be easily installed in buildings of varying ages with varying existing Building Management Systems without increasing risk of system failure."

The software is compatible with building management systems designed after 1995. It doesn't require any new structural data input to work.

A trial of the system at the CSIRO's Newcastle Energy Centre achieved cost and energy savings of up to 30 per cent.
