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.

Reference projects

Low-temperature district heating networks. The basis for modernizing the heat sector.

Renewable energies and waste heat sources are to replace the coal and natural gas sources that have dominated Polish district heating networks up to now. 

First and foremost, this requires a reduction of the system temperature. The study shows the technical, regulatory and organisational measures required to achieve this
and determines the overall potential for decarbonising district heating in Poland.

Energy Policy Simulator

TEP Energy is supporting the San Francisco based think tank Energy Innovation in the expansion of its Energy Policy Simulator (EPS).

SURE - SUstainable and REsilient energy for Switzerland

Sweet - SURE analyses the impact of disruptive events on the Swiss energy system. TEP Energy is working on energy demand topics such as the development of demand for energy sources in Switzerland, the impact of shocks on the demand load and the potential use of large heat pumps.

Future of Gas Study

TEP analysed the energy consumption and greenhouse gas emissions of buildings of residential and service sector in EU27 countries to model different pathways of fossil fuel substitution.

MEDIUS

MEDIUS bridges the gap between green finance and green projects to decarbonize buildings at scale.

Country-specific Market Reports for Buildings

Building Market Briefs (BMB) is a Climate KIC initiative within the flagship Building Technologies Accelerator (BTA) that aims to gather and promote knowledge about the buildings' and construction sector to promote low carbon investment and scaling.

Heating Initiative Switzerland

On behalf of the Swiss Heating Initiative (WIS), the decarbonization of the heating sector will be examined by 2050. Spatial potential analyzes and the Swiss building stock model (GPM) are used.
