ISPT leads the way in indoor environment quality


07 June 2019

ISPT has been awarded a 6 Star NABERS Indoor Environment (IE) rating in four of our properties, 3-5 National Circuit and 4 National Circuit in Canberra, 500 Bourke Street in Melbourne and 100 St Georges Terrace in Perth, giving us more buildings at 5.5 and 6 Star than any Australian building owner.

This year, we’ve rated 22 of our commercial buildings through the NABERS IE program. We have the highest number of certified NABERS IE buildings nationally and our commercial portfolio has an average NABERS IE rating of 4.8 Stars.

A long term track record

ISPT commenced our IE rating program in 2012 and we’ve improved our ratings every year since. We’re proud of our track record in delivering healthy and comfortable spaces for our customers. We build trusted, long-term relationships with them, while they reap the benefits of happy, healthy and productive staff.


Alicia Maynard, General Manager of Sustainability & Technical Services says:

“Our property teams and partners all have an important role to play and we’re able to achieve such great results by knowledge-sharing and working collaboratively with them. Our team, together with our  property managers, mechanical services contractors and building management and control system operators, work in partnership to ensure the successful and efficient operation of our buildings, helping us move the dial towards healthier workplaces for everyone”

ISPT looks forward to continuing these partnerships and delivering shared value for our customers and Investors.
