The Better Buildings Cup has helped the tenant community at 100 St Georges Terrace in Perth to up the ante on energy efficiency and achieve one of the first NABERS Co-Assess ratings.
NABERS Co-Assess is more than a simple way to get a whole-of-building energy efficiency rating. It’s also a collaboration tool that brings building users, managers and owners together to uncover new value.
Just ask the people behind the NABERS Co-Assess rating at 100 St Georges Terrace.
The 24-level premium grade tower, owned by ISPT, already boasted a swag of sustainability ratings, including a 5.5 star NABERS Energy rating for the base building, a 6 star NABERS Indoor Environment rating and a 3.5 star NABERS Water rating.
A solar passive design, a double-glazed façade and an embedded network that supplies power to all the tenancies laid the energy efficient foundations.
But now three of the five commercial tenants – tech giant Microsoft and resource companies Santos and Inpex – have achieved NABERS Co-Assess ratings and gained a clear picture of their office performance and the actions they can take to cut costs and carbon.
“ISPT is committed to creating mutually beneficial social and environmental outcomes for our customers through responsible investment,” says Alicia Maynard, General Manager of Sustainability & Technical Services at ISPT.
“We have taken a portfolio approach to NABERS Co-Assess ratings, which allows us to start a meaningful conversation around whole of building performance and value with customers,” Alicia adds.
A single conversation between the building’s managing agent JLL and ISPT kick-started the process.
“It took just a couple of phone calls to the building’s tenants and we were away,” JLL’s Engineering Services Manager Andrew Turnbull explains.
“Our tenants didn’t have to collate any information or submit any documentation themselves – it was all done by ISPT’s consultant, WSP.
“And there was very little intrusion into the tenant space, other than WSP doing a computer count, because we already had the base building and tenant data.”
Preliminary results suggest both Inpex and Santos will increase their NABERS star ratings. Microsoft, which transitioned to a larger space during the reporting period, will have a solid benchmark for next year, Andrew adds.
“We now have ideas to help our tenants at 100 St Georges Terrace to improve their energy efficiency, with NABERS Co-Assess becoming a tool for tenant engagement on carbon reduction and cost savings,” Andrew adds.
The Co-Assess rating also boosted 100 St Georges Terrace’s points haul in the Better Buildings Cup.
“Engaging with all our tenants has helped us climb the Cup leader board while giving people ideas they can implement in the office and at home too,” Andrew says.
As for JLL, Andrew says his agency, which has a strong track record of sustainability leadership, is proud of its role achieving one of the first Co-Assess ratings.
“It’s been such a seamless activity and so straightforward that there aren’t many lessons to share. But that’s a great story in itself.”
Andrew’s message to other building owners or tenants toying with the idea of a NABERS Co-Assess rating?
“It’s such a simple process – so just do it.”
