Overview

Auckland water provider Watercare Services Limited is the anchor tenant in an eight
level office block constructed in bustling Newmarket in 2013.
73 Remuera Road reflects the growing demand from corporate tenants for green
principled, energy smart work spaces. Watercare occupies three of five office floors in
the building.

Key sustainable features:

  • Located within easy walking distance of train and bus networks - encourages sustainable transport options for occupants
  • High-tech building controls and management system with real time monitoring
  • Energy efficient heating, ventilation and air conditioning system (HVAC).
  • Double glazed façade
  • LED lighting
  • Well-designed waste collection and recycling area
  • End of trip facilities – gym, cycle park and locker facilities

With water being its core business Watercare has the environment and energy issues at the top of its agenda.
While its head office is housed in Green Star rated Watercare House the company’s sustainability manager Roseline Klein says the company wanted to understand its everyday energy performance across the three floors it occupies in the building.

Watercare Services Limited sustainability manager Roseline Klein says undertaking a NABERSNZ rating over its 7563 square metres of office space has proved to be “a painless process”.
The meterage required for a rating was already in place – 18 meters had been installed in the building during the construction period to aid fine-tuning of systems and utilities.
The company took advantage of the free NABERSNZ feasibility assessment which determines a building’s readiness to get started with a rating.
NABERSNZ assessor Pushkar Kulkarni from Total Utilities says lighting, computers and occupant specific plug load have the biggest impact on a tenancy rating.
He says clever configuration of work spaces, occupancy density and sensory lighting controls have resulted in Watercare’s superb 4 star result.

Watercare says it wants to model water and energy efficiency and its 4 star NABERSNZ tenancy rating shows its credentials.

Sustainability manager Roseline Klein says the rating has been “a great experience” and has pushed the company to look hard at its resources and ensure they are better used.
“It’s spearheaded change. For example we’re now trying to ensure our procurement process is not always about cost but energy efficiency too. We’ve recently retrofitted our gym with water efficient shower heads which use nine litres per minute compared with 12 – they offer a better shower experience and use less water and energy,” she says.
Roseline believes a NABERSNZ rating encourages energy awareness and help tackle climate change.

NABERSNZ assessor Pushkar Kulkarni says as Kiwi businesses increasingly look to deliver on corporate and social responsibility and think about long-term business sustainability a NABERSNZ rating demonstrates a willingness to ‘walk the talk’.
“The NABERSNZ tool is set to become increasingly important in New Zealand.”
