Case study -4 Mort Street

The retrofit of 4 Mort Street in Canberra from 2010 aimed to improve the building's energy efficiency and NABERS rating. Key steps included an energy audit, building simulation, and upgrades to the HVAC system and lighting. This included changing to natural gas heating, installing a BMS and VAV air distribution. The retrofit was successful, increasing the NABERS rating from 2 to 4.5 stars, reducing electricity use by 30% and annual emissions by 70%, saving $120,000 per year.
