Summary of the project

One of the most important challenges in the building sector to achieve the climate targets is the reduction of energy demand through highly efficient buildings (NZEB) or energy-efficient refurbishment. The decisive role here will be played by the rapid (serial, i.e. with a high degree of prefabrication), in-depth energy refurbishment of existing buildings. This requires cost-effective renovation systems that are easy to apply from the outside. In addition, quality assurance concepts must be established at all levels, from the planning of a building's energy concept to the verification of efficiency after renovation.

Expected results of outPHit

  1. Evaluation and further development of existing prefabricated elements and one-stop-shop approaches (analogous to the Energiesprong concept) that fulfil the passive house criteria for renovation measures (EnerPhit standard).
  2. Renovation of demonstration properties in all participating countries of the project partners with the involvement of all relevant stakeholders: Municipalities, local authorities, financiers and investors, as well as planning and executing companies.
  3. Development of monitoring concepts to evaluate the increase in efficiency through serial refurbishment.
  4. Development of decision support tools for cost-effective, serial refurbishment and quality assurance methods for the evaluation and certification of measures.
  5. Publication of the results, organisation of training workshops and conferences.

Focus of the University of Innsbruck

The focus of AB EEB is on the further development, optimisation and evaluation of energy-efficient solutions for the serial refurbishment of buildings. The costs of energy efficiency measures, alternative heat supply concepts and renewable energy generation are determined in order to put together cost-optimised packages and make recommendations. The solutions are presented using decision support tools. In addition, monitoring concepts are developed and implemented for the best-practice projects in order to evaluate and compare energy efficiency, thermal comfort and indoor air quality before and after refurbishment.
