An office development at 171 Collins Street in Melbourne’s CBD has become the first development in Victoria to achieve a six star NABERS energy rating.

It is also one of only three commercial office buildings in Australia to achieve this rating without green power or renewable energy back-up such as solar, wind, or geo-thermal.

The property was developed and currently owned by Cbus Property and Charter Hall. It is made up of an 18-level office called the Tower building, plus seven levels of PCA boutique offices within the Mayfair building.

“The property achieved its design at 18 months after practical completion, with only 65 per cent occupancy,” said Knight Frank Head of Sustainability Nick Mavropsi.

“The challenge was to try and improve the five star NABERS energy rating to possibly 5.5 or six stars, while maintaining premium environmental conditions to all tenants and complying with all lease commitments,” said Mr Mavropsi.

“We were able to achieve a six star NABERS energy rating through a variety of initiatives,” Knight Frank Senior Facilities and Engineering Manager CJ Harshana Wijewardane said, who was in charge of facilitating the energy rating initiative.

“Fine-tuning all of the services was crucial to maximise the efficiency of the installed plant and equipment, including the utilisation of the smart tools available.

“These include highly-refined EMS, under floor air distributed system (UFD), access control high level integration and the co-generation system.

“Processes were applied to create efficiencies across services and processes within the building, including UFAD stratification and air volume/temperature control; improved after-hours air conditioning strategy; optimum start-stop of HVAC plant; increasing cogeneration plant efficiency and dependency; and retrofitted LED technologies on some areas to accentuate architectural features of the building,” Mr Wijewardane said.

Knight Frank wants to successfully continue to help deliver energy efficient buildings for the sake of sustainability.
