Survey results on building refurbishments to the EnerPHit energy efficiency standard

The EU project outPHit [3] aims to emphasize the potential of serial refurbishment solutions and support end users in the refurbishment process with tools, guidelines and checklists. Based on demonstration projects throughout Europe, outPHit is investigating solutions for EnerPHit refurbishment with high energy standards and components with a high degree of prefabrication. In order to evaluate their acceptance, questionnaires were designed and analyzed for the residents of the renovated buildings.

Partners with demonstration projects translate these into local languages and distribute and collect the completed documents. The questionnaires collect qualitative information on user satisfaction based on residents' well-being and perceived changes in their living conditions after the renovations, as well as how the use of new mechanical equipment or renewable energy affects their daily lives. This data publication contains the questions and analyses as well as their elaboration in a report.
