ASIEPI is the acronym of the full project name: "Assessment and Improvement of the EPbd Impact (for new buildings and building renovation)".  The project ran over two and a half years and its main objective has been to formulate suggestions to policy makers on how to improve the quality and the impact of the regulations on the energy performance of buildings with respect to 6 specific issues:

• intercomparison of the levels of the EP-requirements
• impact, compliance and control of legislation
• effective handling of thermal bridges
• stimulation of good building and ductwork air tightness
• support for the market uptake for innovative systems
• stimulation of better summer comfort and efficient cooling

Several major aspects of each of these topics have been analysed.  The results are documented in a full suite of project materials.  Among others, these materials provide insight in the potential problems and give guidance with respect to possible solutions.  However, as the project had to conform to the objectives of the IEE-SAVE programme, which focuses on dissemination, no new, ready-to-use methods were developed.  Instead, the (often hidden) challenges were analysed and existing best practice to achieve more effective EPB-regulations was highlighted.
