Getting "net-zero energy ready" will take collaboration between all orders of government and the buildings sector as a whole. Here are some of the ways we will make progress together:

• Starting in 2018, fund research, development and demonstration projects to lower the cost of building high-performance and netzero energy ready homes and buildings.

• Launch a new program to support code adoption and compliance in 2018-19.

• Publish first tier of more stringent model codes for buildings and homes in 2020.

• Publish additional tiers of increasing stringency, with the aim of establishing net-zero energy ready codes in 2022.
