Case Studies

The benefits of investing in energy efficiency in the building sector are becoming clear – more energy efficient buildings will be cheaper to run and are likely to attract higher rents and property prices.

The case studies below provide examples of the Energy Rating Scheme in action. 


A model for energy savings - 4 Mort Street Canberra

The ACT Public Trustee House, 4 Mort Street Canberra, had problems common to many ageing commercial buildings. It had a poor energy rating, a heating, ventilation and cooling (HVAC) system near the end of its operational life and some tenancy leases were due to expire.

Key facts:

  • Improvement from 2 to 4.5 star NABERS Energy rating
  • Investment of $1.5 million with a payback period of as little as one year
  • Increase in asset value estimated at $1.4 million
