Scope of project
The ccem-retrofit project is based on national and international research and development projects
that are collaborating to promote and improve cost effective low energy renovation of existing
buildings. The project focuses on typical apartment blocks representing approximately 40 % of the
European dwelling stock. It concentrates on:
- Minimising the primary energy consumption (in the range of 30–50 kWh/(m²·year) for heating, cooling and hot water, per gross floor area),
- Optimising the integration of solar energy use,
- Improving electrical building components and control functions
- Increasing living comfort by better space use,
- Assuring good thermal and acoustical comfort, good indoor air quality and daylighting conditions,and
- Assuring a fast, high quality and cost-effective construction process.
