Energy renovation in residential areas has always aimed to reduce the total energy consumption of buildings. But we need to become even better at reducing energy consumption if we are to reach the ambitious goal of Denmark becoming a CO₂ neutral society by 2050. Aside from looking good in both the operating budget and the CO₂ balance, reducing energy consumption also has a social, cultural and health-related impact on residents and users of buildings.
In REVALUE we will make a full-scale demonstration of two renovation projects in areas with different residential compositions, and study their effects as regards the reduction in energy consumption and the impact on health and well-being. We renovate with a focus on energy savings while also finding a method to determine the added value generated by renovation, such as a better indoor climate or new urban spaces in the built environment.
Better residential areas with low energy consumption
The aim is reduce energy consumption in demonstration buildings by at least 50 per cent. This involves elements such as new facades, windows and roofs and, in this way, the renovation work will significantly change the indoor climate in the buildings and the architectural expression in the area.
With a comprehensive combination of features such as sensor-based energy monitoring, anthropological field studies, physiological tests and indoor climate assessments, we will develop a model to measure the total value of energy renovation, including technical, social and cultural aspects. In this way, we are going one step further with a model that also includes people’s subjective experience of living with renovations.
Complex data lead to good decisions
Another task in the project is to identify options for energy savings and social value creation in the renovation process itself. This involves making transport to and from the residential area more efficient, managing logistics at the building site and minimising material waste. It also means involving residents in the building process in a socially sustainable way to ensure support and ownership of the people living in the residential areas.
The idea is to build a model that can find relations between the technical, social and cultural aspects of energy renovation. This means that each energy renovation project can be indexed so you can see its value on a scale from 1 to 100. A developer will be able to use the model to test different priorities in a renovation design and thereby find the most suitable renovation solution for the individual residential area and provide the most value for money.
