Description of a whole house renovation system certification concept
Through a certification process of such renovation systems, the quality of the system, the overall component performance, and also including critical points such as thermal bridges, airtightness or ventilation heat recovery, can be assured to fulfil the ambitions required for deep renovation projects, such as EnerPHit retrofits. Furthermore, through the examination by the certification process, specific performance values of the deep renovation systems are determined and made available, by transparently describing U-values, thermal bridge coefficients or ventilation heat recovery efficiency within the certificate so these values can reliably be used for the energy efficiency planning of the renovation projects. By offering approved descriptions of the airtightness concept and further information about the systems, stakeholders applying such renovation concepts can select a better renovation system.Criteria for a whole-house renovation system certification concept
Description for a design-stage-approval concept
This paper aims to draft a concept for the design stage approval concept (DSA) and the resulting document, Design Stage Approval Letter (DSAL). The approach will be applied to the outPHit renovation projects and will help the involved parties achieve the desired efficiency standard. The results of this test will be integrated into the final version of the DSA concept.Criteria for a design-stage-approval concept
Renovation approach documents
Detailed descriptions of the renovation approaches employed for many of the project's case studies are available for download in the information section of each case study on the outPHit website. These documents deliver insight into how various outPHit case studies are being retrofitted to meet the EnerPHit standard for renovations in line with Passive House principles and provide a comprehensive overview of each building in question, its condition before the retrofit and the planned improvements in terms of air tightness, technical systems, insulation and building components.
Description of a certification scheme on "verified building performance"
This report outlines the concept developed to measure and evaluate the performance of deep retrofit projects implementing the outPHit methodology in the field. Efforts are made to streamline and automate most steps to make the building performance evaluation process, with sound consideration of measuring uncertainty, accessible to new target groups, such as architects and engineers or even builders. A procedure to systematically evaluate elementary living quality parameters has been identified.District evaluation reports from Greece, Austria, Bulgaria and Germany
This study of renovation scenarios in a Greek, Bulgarian and an Austrian district, as well as for all of Germany, shows how renovations carried out with a rigorous focus on superior energy performance can avoid lock-in effects, leading to vast energy savings and significantly lower emissions, even at consistently more comfortable indoor temperatures. The scenarios for each district were conducted with DistrictPH, an open-source, Excel-based tool developed by the Passive House Institute, capable of calculating detailed energy balances for entire districts as well as their development over time.
