sEEnergies - Cost potential curves for refurbishment strategies in Europe
Buildings accounts for 40-50% of the overall consumption for electricity, heating and cooling. The current energy efficiency (EE) measures focus almost solely on improvements of the building envelope and would enable 25% energy savings in the EU. State-of-the-art research shows that buildings level EE could be higher than 30% and that combining these savings with changes in the supply system can increase the EE further, at lower costs.
Aspects which are considered in the H2020 sEEnergies project, are related to the building refurbishment strategies and their associated costs. Residential and services buildings constructed in recent years implement moderate to high performance standards but will likely undergo further refurbishment until 2050. From an investor's perspective, additional efficiency improvements of the building envelope might be costlier as compared to renewable heating solutions by that time and therefore, divergent interests need to be balanced. As the building stock and its current performance standard is very heterogeneous in different European countries, additional sources for cost development of different building types and materials shall be applied by expanding the existing Heat Roadmap Europe dataset to all European countries.
sEEnergies will provide specific results on the:
- EE potentials in the building envelope and electricity savings considering the cost aspects of refurbishment measures
- Balances between onsite and system renewable energy and EE measures
- Energy saving and EE cost curves for the build environment for member states using detailed building level data
TEP Energy is work package leader and main contributor of work package 1, delivering cost potential curves for the built environment.
