Determining office tenancies energy end use


Australian Government



Energy Efficiency Council


Office building energy costs are often borne by two different groups: owners and tenants. While owners are typically responsible for the base building including foyers, lifts, HVAC, and bathrooms, tenants generally cover the lighting, IT and other ‘plug load’ or appliances in their tenanted space.

In this report, the Energy Efficiency Council (EEC) analyses how much electricity and gas use is attributable to tenants in Australian office buildings based on a survey of CitySwitch signatories and data from the National Australian Built Environment Energy Rating System (NABERS).

The report looks at the main uses for energy and seeks to establish the energy savings opportunities available in office tenancies to 2030. Its objective is to facilitate the uptake of and investment in energy upgrades that offer the largest energy and emissions savings for tenancies.
