With a commitment to reducing energy consumption and carbon emissions, the Austrian government has implemented various initiatives and schemes to encourage homeowners to improve the energy efficiency of existing buildings. The most significant initiatives include the following:

• "Sanierungsbonus" — the Sanierungsbonus is a flagship initiative aimed at incentivizing energy-efficient renovations of existing buildings. Under this scheme, homeowners and landlords can receive financial support for a wide range of renovation measures, including insulation, window replacements, heating-system upgrades, and the installation of renewable energy technologies. The bonus provides a subsidy of up to 50% of eligible renovation costs, with higher rates available for low-income households. To qualify for the Sanierungsbonus, applicants must meet certain energy efficiency criteria and comply with relevant building regulations.
• "Raus aus Öl und Gas" — this initiative focuses on phasing out the use of oil and gas for heating in residential buildings and transitioning to more sustainable alternatives. Homeowners who replace their oil or gas heating systems with energy-efficient alternatives, such as heat pumps, biomass boilers or district heating, can benefit from financial incentives and subsidies provided by the government. The Raus aus Öl und Gas program aims to reduce dependency on fossil fuels, improve air quality and promote the adoption of renewable energy sources for heating.
• "Mustersanierung" — as part of this program, comprehensive renovation projects of public or commercially used buildings are funded. The subsidies originate from a public fund called the Klima-und Energiefonds. It includes measures to improve thermal insulation, and measures to use renewable energy sources and increase energy efficiency.

Additionally, there are also a variety of sponsored schemes for improving the energy efficiency of existing buildings available at the state level.
