Renyi ensured sustainable, code-compliant design at Newgreens, balancing energy efficiency with architectural vision.

As Australia embraces greener urban development, the Newgreens Precinct demonstrates how architectural vision and sustainable engineering can work in harmony.
Playing a central role in that success is Renyi, a Sydney-based consultancy specialising in sustainable building design and performance compliance. Led by Director Allan Ang, Renyi was tasked with ensuring the project met environmental goals without compromising the architectural intent.
“We focus on providing professional design and architectural advice that delivers not only code-compliant solutions but enhances the environmental sustainability and visual value of each project,” says Allan. “Our goal is always to support projects that will contribute to cleaner, greener cities.”
At Newgreens, Renyi’s primary role involved Section J energy efficiency assessments, as outlined in the National Construction Code (NCC). This included evaluating the façade and services systems to ensure code compliance, buildability, and resource efficiency. “Our job was to assess the performance of the façade and the services—like insulation, ventilation, and air conditioning—so that we could provide realistic, code-compliant solutions,” explains Allan.
A standout challenge was the clubhouse, which features a dramatic west-facing glass façade and an articulated butterfly roof. While visually striking, the design posed comfort and performance risks, particularly in Sydney’s harsh afternoon sun.
“The façade was elaborate—mostly glass and west-facing. It created comfort challenges,” Allan said. “We had to carefully assess and apply glazing performance data to meet both thermal comfort requirements and the architect’s design vision.”
The angled roof also complicated insulation and HVAC installation. “The roof wasn’t flat—it was tilted and sculptural. That made it difficult to run services efficiently. We identified those issues early and worked through several iterations to ensure performance standards were met.”
Through thermal calculations and simulation modelling, Renyi proposed energy-efficient yet achievable solutions that aligned with construction requirements and regulatory obligations. Their focus was not just on compliance, but on real-world performance.
“This wasn’t about introducing high-tech systems—it was about getting the fundamentals right,” says Allan. “Section J is about energy efficiency, but the outcome is comfort. It’s about choosing the right materials, so the space doesn’t overheat, and the aircon doesn’t have to work overtime. That’s how you reduce long-term carbon impact.”
Renyi’s contribution extended across the entire precinct, including independent living units and communal facilities. Their approach prioritised early-stage collaboration to align performance requirements across teams.
“There were a lot of meetings and coordination,” Allan recalls. “Each time a new party came on board, it introduced new perspectives—and new challenges. It really highlighted how important it is to engage the right people at the same time to resolve complex design issues.”
Renyi’s strength lies in this collaborative clarity, helping balance client expectations, construction practicality, and environmental ambition. Their role at Newgreens reflects a broader commitment to delivering sustainable building solutions that are both technical and tangible.
“The Newgreens Precinct is architecturally refreshing,” Allan reflects. “The clubhouse is a beautiful building, and it was rewarding to work on the independent living units too—knowing that our input supports thermally comfortable, sustainable homes for older Australians.”
While this wasn’t Renyi’s first aged care or retirement development, it was a standout for its design complexity and layered stakeholder environment. For Allan, the project was a reminder of the power of early integration and honest collaboration.
“We’ve seen how critical it is to involve all consultants early,” explained Allan. “When you do, you save time, reduce rework, and achieve better results.”
Renyi continues to lead with practical, code-informed solutions that champion both comfort and creativity. The Newgreens Precinct stands as a prime example of that mission in action.
