In this project, a model was developed for energy efficient and moisture-safe renovation solutions. The objective of the project was to answer the tightening energy efficiency requirements by developing an operations model that ensures good indoor air quality and optimizes renovation. The comfort, productivity and service ability of the renovated space was taken into account. During the project, the requirements, functionality levels and procedures were determined for a renovation concept, which is energy efficient, reliable and ensures good indoor air quality. The aim was to make sure that the new energy efficiency renovations don’t lower indoor air quality in a Finnish climate, and that the needed repairs can be optimized according to needs and demands. This concept can be used in buildings, where different levels of moisture, mould or rot damages have occurred, to guarantee that the renovation doesn’t cause a risk of malfunction in changed climate conditions.
Objectives:
- To create a tool for assessing the effects of the energy efficiency renovations on the quality of the indoor environment (air quality, thermal comfort, lighting) on different renovation sites considering the varying building types and ages. The tool was created to confirm the success of renovations even in buildings, where moisture, mould or rot damages have occurred
- To verify the success of the renovations based on the concept by way of measurements and user surveys, focusing on the healthiness and comfort of the indoor environment.
- To create requirements and an operations model for property and building industries that make sure the energy efficiency requirements won’t lower the quality of the indoor environment, even in the older buildings where mould and rot defects are possible. The operations model can be used in all stages of the chain of building production.
The ENERSIS-project was carried out by the VTT Technical Research Centre of Finland, the research unit of Structural Engineering at Tampere University of Technology, and the Aalto University School of Electrical Engineering/Lighting unit. International co-operation was done with the following research institutes: Fraunhofer Institute for Building Physics (IBP) in Germany, and Dalian University of Technology in China.
