Cbus Property's recently completed $265 million project at 83 Pirie Street, Adelaide, has earned a string of firsts and global status for sustainability.
The building is registered to obtain a 6 Star Green Star Design and As Built Certified rating. Additionally, it is designed to achieve a 5.5 Star NABERS Energy rating, and a WELL Platinum rating. These ratings place the building among the world's most sustainable.
Designed by architecture studio Woods Bagot, the state-of-the-art building was developed by Cbus Property and constructed by Multiplex. Located in the heart of Adelaide's business district, 83 Pirie Street has more than 30,000 square metres of commercial space across 22 levels with street-level retail and hospitality.
As Adelaide's most sustainable office tower, 83 Pirie Street is the city's first all-electric carbon-neutral ready building and the first commercial and retail mixed-use building without natural gas. In addition, the Property Council of Australia has rated 83 Pirie Street as South Australia's first A-grade building.
Cbus Property engaged dsquared Consulting to provide environmentally sustainable design for 83 Pirie Street.
The agency's remit included optimising the project's façade and systems performance, energy modelling and Greenstar, NABERS Energy and WELL certification.
Developed in Australia, Green Star is an internationally recognised sustainability rating system for the built environment offering a framework of best practice benchmarks for sustainability. The WELL rating system uses performance-based criteria to measure, monitor and certify elements of the built environment that impact human wellbeing. It aims to enhance the performance of building occupants through improved nutrition, mood, fitness and sleep. NABERS measures the energy efficiency, water usage, waste management and indoor environment quality of a building or tenancy and its environmental impact.
According to dsquared Consulting Director, Paul Davy, Cbus Property required the project to achieve the highest sustainable ratings.
“So, we aimed for world leadership in sustainable design – six-star Green Star and WELL platinum ratings".
Davy says final certification will be granted based on the building's performance over set periods following completion.
The project’s sustainability features include a high-performance façade with a serrated profile to reduce direct solar gain, extensive end-of-trip amenities to encourage active commuting, high-performance VAV air-conditioning, high-efficiency water systems with rainwater storage and re-use, all-electric building, carbon-neutral ready and extensive space allocation for occupant health and wellbeing with access to the outside air.
The design and construction teams specified Kingspan Insulation's Kooltherm products to enhance the building's thermal performance.
Ceiling and Wall Contractors installed approximately 4000 square metres of Kooltherm products in the project’s car park, plant room and 20th level.
Contract Administrator, Shaun Harvey, says Kingspan products are always their first choice.
“We use Kingspan all the time. Their products meet specifications and are easy to cut and install. There are no lead time issues, the product is always there waiting for us”.
The Kingspan Kooltherm range is an extensive range of rigid thermoset phenolic insulation for roofs, walls and floors. It is the thinnest commonly used insulation board for any specific R-value., which means designers and builders can minimise insulation thickness compared to other conventional insulations to achieve the same performance.
The range also has independently verified fire performance characteristics. As it is a thermoset material, it hardens and chars in fires, giving off very little smoke, unlike thermoplastics, such as polystyrene, which melt, soften, and give off thick black smoke. Not only sought-after in the commercial building sector, Kooltherm rigid insulation boards are quickly gaining popularity in the residential category and modular construction.
Kooltherm is the thinnest commonly used insulation with the highest R-value in the market. Its design prevents water vapour, reduces thermal bridging, and complies with AS/NZS 4859.1:2018.
In 83 Pirie Street, 45mm and 80mm thicknesses of Kooltherm K10 G2W White Soffit Board were installed and 35 mm for Kooltherm K17 Insulated Plasterboard.
Kooltherm insulation boards are also lightweight, making them easy to transport and handle and fast to install. Moreover, the thin profile of Kooltherm products allows the building industry to maximise lettable space and lifetime property value.
