Our Waterwise Building Program acknowledges the efforts of building owners and their ongoing commitment to water efficiency, to achieve a significant improvement in water use.

This free program provides a benchmark for water efficiency in businesses further demonstrating the achievements they have made in sustainable water management.

Case studies show that benchmarking water use and planning for improvement can reduce operating costs, including sewer volume charges and the costs associated with heating, pumping and treating water.

Program benefits

  • Recognition as a leader in water efficiency by Water Corporation and Property Council of Australia 
  • Exclusive access to the waterwise logo
  • Access to tools such as data loggers and resources (stickers and posters) to encourage waterwise behaviours
  • Potential for improved sustainability ratings and reduced operational costs and water use achieved by improved water efficiency
  • A competitive edge when promoting your business as a sustainable place to work
  • Invitations to workshops, offers, networking and industry events
  • How to become a waterwise building

    To be eligible to participate in the program, a building must have a NABERS office water rating (applies to buildings >2,000 square metres). Program parameters will be annually reviewed by the program administrators and may be expanded without notice.

    Each year we review endorsement applications to categorise customers against the eligibility criteria and advise recognition levels. Customers eligible for Gold recognition will be notified once their application is verified.

    Gold waterwise buildings will be invited to submit an application for recognition as Platinum Waterwise Building of the Year. 

    Recognition categories

     
     Recognition level Water cooled benchmark NABERs water rating  Other cooled benchmark*  NABERS water rating
    Endorsed (industry baseline) 0.61 – 0.75  3.5 – 4.0   0.48 – 0.61  4.0 – 4.5
    Gold**

    < 0.61 

    + certification or criteria

    4.0 > < 0.48   4.5 >
    Platinum** Must meet relevant Gold criteria above, plus nominate to be considered for Platinum Waterwise Building of the Year.

    *Other cooled can include natural ventilation, hydronic, ground loop, geo-thermal and central system.

    **To be eligible to receive Gold or Platinum levels of recognition a current NABERS water rating is required. This allows us to independently validate the results of high performing buildings before they are recognised.

    Water use performance

    To calculate your water use performance, divide your annual water use (based on reading year – contact us if you need the data) by your NLA. This gives your water use performance in kilolitres per square meter per year.

    Tip: Use your submeter data to subtract water use from other facilities, such as food or retail outlets, in your calculations.
