Caring for future generations

We provide specialist services at all stages of the building lifecycle to minimise environmental impact and enhance sustainability; from design through installation, commissioning and ongoing operation and maintenance.


Integrated Design Approach

Improved lifecycle design for low initial and ongoing environmental impact including the use of leading energy and water modelling and BIM capabilities to improve material selection and reduce waste. A.G. Coombs understands how buildings operate and this knowledge delivers better building services design.

Energy Efficiency Maintenance

We maintain a large number of 5 and 6 Star Green Star and 5 Star NABERS buildings using a unique energy efficiency focused maintenance approach that delivers system performance, asset protection and minimised environmental impact.

Building Energy Optimisation Programs

A.G. Coombs tunes building energy systems in leading national property portfolios. Typical results see a ½ to 1 Star NABERS Energy improvement with a simple payback in less than one year. Several cases have seen 2+ Star improvements. Technical capabilities include programming down to code level through to innovative multi systems strategies. This can include embedded processes to cap energy usage whilst maintaining systems performance / internal conditions. Multiple automated reporting options are available for the full range of stakeholders.
