“Energy Efficient Ventilated Façades for Optimal Adaptability and Heat Exchange enabling low energy architectural concepts for the refurbishment of existing buildings.”

 

E2VENT project is a research project supported by the European Commission under the Horizon 2020 programme with the main aim to develop, demonstrate and validate a cost-effective, high energy efficient, low CO2 emissions, replicable, low-intrusive, systemic approach for retrofitting of residential buildings, able to achieve remarkable energy savings, through the integration of an innovative adaptive ventilated façade system. The project has just completed the 30th month of the remaining total length of 42 months.

 

E2VENT proposes a new adaptable system, consisting of a ventilated façade to improve the thermal resistance of building envelope and a ventilation heat recovery unit to improve the inner air quality. E2VENT presents an innovative technology based on smart heat recovery units (SMHRU) and latent heat thermal energy storage (LHTES) which are going to be integrated into the ventilated façade cavity. Instead of a large duct system transporting ventilation air throughout the whole building, smaller heat recovery units will make possible a mechanical air renovation inside different rooms, allowing for heat recovery of the ventilation air.

 

The installation of the system has been already performed on a test bench in Anglet, France. The test bench allows installing the systems on a 2,6 m high and 2,7 m wide wall associated with a cell that is fully equipped with HVAC systems and measurements. This allows for assessing the energy performance of those systems in the associated zone. Another cell with an identical wall has been renovated with an ETICS and serves as a business reference.

 

The validation of the E2VENT technologies will be demonstrated through their integration and execution in two different demo buildings under different climatic areas in Europe (continental and oceanic).

  • The first pilot building is located in Burgos, Spain, it is a part of a set of residential blocks, which were built in 1880 and served as the military hospital. Nowadays, these buildings belong to the university and are designed to be used as classrooms.
  • The second pilot building, located in Gdansk, Poland is multi-story residential building constructed in 1950. The building monitoring will include measurements of: energy consumption, external and internal conditions and the performance of the two renovations will be compared.

This project is supported by the European Commission under the Energy Theme of the Horizon 2020 for Research and Technological development. Grant Agreement number 637261
