As an independent, self-funded regulator, the Board maintains the register of qualified architects, publishes resources to inform both professionals and the public, and promotes discussion about the value of architecture in the community, including professional standards and ethical practice in design.

Victorian Energy Upgrades
Victorian Energy Upgrades is a government initiative that’s delivered by the Department of Energy Environment and Climate Action.
The program offers discounts to help Victorians upgrade to more energy-efficient appliances, like heating and cooling, induction cooktops, and hot water systems. This helps households save on upfront costs, lower their energy bills and reduce energy use. The program will save 37 million tonnes of greenhouse gas emissions for Victoria between 2022 and 2027. That’s equivalent to taking more than 11 million cars off the road for a year.
