The NSW Department of Climate Change, Energy, the Environment and Water (DCCEEW) has released the Improving energy efficiency in residential apartments: Practical insights report. The report draws on analysis, modelling and research undertaken by Urbis for DCCEEW through the NSW Apartment Energy Efficiency Baseline Study. The study established the first comprehensive baseline of residential apartment energy performance across the state.

With over 1.2 million people living in apartments across NSW, many residential buildings have opportunities for energy cost savings, improve thermal comfort and reduce emissions.

The Practical insights report translates the study’s findings into practical guidance to support owners, renters, councils, strata managers, owners’ corporations, and industry improve apartment energy performance. It also identifies high-impact upgrades that can reduce costs, improve comfort and lower emissions.

The study brought together multiple datasets to establish foundational energy performance baselines, and develop representative apartment archetypes based on key attributes such as age, location, size and building fabric.
