The report contributes to research in the residential buildings sector, by conducting an independent study into, and providing examples from the building industry of, the changes that have been implemented and are associated with constructing more energy efficient dwellings.Changes Associated with Efficient Dwellings project—Final Report 2017 This report was commissioned by the Department of the Environment and Energy who have managed the project on behalf all Australian jurisdictions under Measure 31.2 of the National Energy Productivity Plan.In addition, a de-identified version of the model was created, segregated by building type, to enable interested parties to access the data collected, without compromising confidentiality of the buildings included in the database.The data contained in the model provides estimates of the building stock, energy consumption by fuel and end use (where possible), and greenhouse gas emissions by state/territory and region, from 1999 to 2020, with 2009 as the base year.Building Code Calculator An issue critical to understanding the costs and benefits of increased energy efficiency stringency in the National Construction Code is that of Learning Rates.This is the rate at which the extra costs that occur delivering new or innovative products decrease over time as firms adapt, adopt new technologies and revise their designs and/or production processes.insulation and weather sealing, are often poorly installed by builders, thus leading to houses that have lower energy efficiency performance than expected.There has also been little data collected on newly built houses to quantify air‐tightness and assess the quality of installation of insulation and heating/cooling ductwork.

Residential Buildings Regulatory Impact Statement Methodology—Report 2017 This report was commissioned by the Department of Industry, Innovation and Science as an input to Measure 31 in the National Energy Productivity Plan, 'Advancing the National Construction Code'.

The Committee presented an interim report on 20 April 2015 and its final report on 5 June 2015.

The Australian Government formally presented its response to the Committee’s reports on 27 April 2016.

Pathways to 2020 for Increased Stringency in New Building Energy Efficiency Standards: Benefit Cost Analysis The Australian Government commissioned the development of software to estimate the emissions reduction and energy savings arising from future changes to the National Construction Code.

This calculator in the form of an Excel spreadsheet is accompanied by a report.

The report identifies two prioritised short-term research programs that could be undertaken to inform a future regulation impact statement (RIS)—that is likely to be undertaken in early 2017—relating to possible changes to the energy performance requirements for residential buildings in the 2019 edition of the National Construction Code.
