Best practices

Best practice handbook of sustainable building renovations

The study examines both public and private sector approaches to financing building renovations and provides valuable insights into the past and current use of financial models, procedures, and processes. The findings highlight the challenges faced in financing renovations, particularly in the private sector, where the lack of access to financial resources and the complexity of shared ownership can delay or halt projects. In contrast, public sector renovations tend to be more widespread, often benefiting from larger-scale investments and more available information.

Key findings include:

  • In Austria, there is a diverse range of funding schemes, but many large-scale public renovations face challenges such as a lack of funding and high renovation costs.
  • In Hungary, most public energy-efficiency renovations are funded through non-refundable grants, though municipalities often face administrative burdens and a lack of long-term financial solutions.
  • Slovenia relies on energy performance contracting (EPC) and EU funding schemes, though there is a lack of promotion of successful financial solutions, and legal and procedural obstacles hinder faster implementation, particularly in the private sector.

This compilation of best practices aims to facilitate knowledge exchange and discussion among stakeholders in Austria, Hungary, and Slovenia, offering insights into successful financial strategies for building renovation. The report will serve as a valuable resource for future national working groups and platform discussions, where the countries can learn from each other and explore ways to overcome common challenges.

The findings presented here will also contribute to the continued identification and analysis of good practices, culminating in the development of a refreshed catalogue of 50 best practices later in the project. This ongoing collaboration will foster the growth of sustainable investment practices and promote the scaling of energy-efficient renovation across the region.
