IAG were looking to achieve a NABERSNZ rating for their building at 1 Fanshaw Street, Auckland feeding into their energy efficiency and scope 2 carbon emission reduction. As a joint engagement Colliers, the Property Manager were also looking to improve asset value. The building originally had a 5-star NABERSNZ, however this had lapsed and energy usage was increasing at 9% per year.
Metering was installed to a standard that could achieve a Basebuild NABERSNZ rating. The metering provided visibility to optimise operation of the mechanical plant. ESP was engaged to complete a monitoring and targeting programme that identified energy and costs savings opportunities for the building.
Working together, the building has now achieved a Basebuild NABERSNZ rating of 5.5 Stars rating. This rating is amongst one of the highest published basebuild ratings.
