Below are some real world examples of what we’ve been able to help commercial property clients achieve. If this sounds good, why not give us a call.

IAG
Challenge
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.
Solution
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.
Outcome
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.

Bayleys – Harbour Grounds

The team at Bayleys manage the large property portfolio in Wynyard Quarter now named Harbour Grounds. The portfolio comprises 7 premium Auckland waterfront offices with 7,000 tenants occupying 88,000 sqm. With a change of ownership, Bayleys needed to rapidly get up to speed with the buildings performance and continue improving its value as required by the new overseas owners.

NABERSNZ – Bayleys House
NABERSNZ – basebuild & tenancy
The list of sustainable credentials for Bayleys House continues to grow with not one but two NABERSNZ ratings.
A collaborative sustainable approach between landlord, property managers and tenants has delivered a high 4.5 star NABERSNZ base building rating for Bayleys House in Auckland waterfront’s dynamic commercial VXV Precinct.
Realty group Bayleys, who leases its head office in the building, has also earned a 4 star NABERSNZ rating for its tenancy – reflecting its strong commitment to the environment.
Managed by a partnership of Australasian asset managers; 151 Property, and Bayleys Property Services, optimising building performance and offering healthy, comfortable workspaces for tenants is top of the agenda.
NABERSNZ assessor Hong Lee says high quality mechanical services including a fresh air system with a connected heat pump, have been instrumental in the achievement of a 4.5 star NABERSNZ rating for Bayleys House. The integrated heat pump provides consistent heat efficiency and reduces the need for electrical heating to kick in when the building cools down in winter.
Bayleys House has 70 energy monitoring meters spread across the building.“We can monitor down to 15 minute segments of energy use and you can even see the impact on air conditioning services if a staff member comes to work at 3am,” says Hong.
He says well-designed tenancy office services including LED lighting and occupancy sensors which switch off after 30 minutes, have driven the 4 star NABERSNZ tenancy score for Bayleys head office. A regime of normal daytime working hours has also propelled the Bayleys head office’s optimum energy performance.
