Select Services Air Conditioning and Refrigeration, A VAE Group Company, are proud to have worked with Hutchinson Builders to provide the Mechanical Services for Manunda Place located in Darwin’s CBD. Manunda Place provides additional PCA A-grade office accommodation for the NT Government and has changed the face of the Darwin CBD.
Construction of the nine-storey building on the corner of Knuckey, and Cavenagh Streets started in January 2019, and reached practical completion in July 2020.
The plantroom is located on the rooftop at Manunda Place, and the web based Building Management System (BMS) integrates all mechanical services, monitoring of hydraulics services, lifts, and fire services.
The following mechanical services were undertaken by Select Services.
• Two 820kW Smardt Water Cooled chillers
• Evapco Cooling Towers
• Two CHW Pumps
• Two Condenser Water Pumps
• BMS with energy monitoring for NABERS assessment
• Two perimeter Zone AHUs
• Two Center Zone AHUs
• Two Outside Air Pre-conditioning units
• Two Stair Press Fans mounted at the top of each stairwell
• Roof mounted Smoke Exhaust fan, serving the office levels
• Four Roof Mounted Fans (TEXH x 2, Gen EH x 1, Retail KEXH)
• Plantroom EXH controlled from refrigerant detector
• Passive ventilation to the lift shafts
The project also involved the construction of a new five level multi-storey carpark on Litchfield Street.
As proud Territorians, Select Services were thrilled to have worked closely with Hutchies in the territory, and to be involved in the first major office building project in the past two years in Darwin.
Manunda Place Darwin is now the most energy efficient building in Darwin, receiving a 5.5 Star NABERS rating in December.
Manunda Place has an Energy Intensity of 300Mj/m2 per annum. The actual energy used was 380,345kWh less than the 5 star Energy Model results. This would equate to over a $100k saving in electricity outgoings.
We are very proud of the energy saving resulting from the mechanical design put together by the outstanding Select Service / VAE Engineering team.
Congratulations to the Hutchinson Builders for this outstanding achievement.
The 5.5 Star rating is valid from 23/11/2021 to 23/11/2022.
