This project is supported by the European Commission under the Energy Theme of the Horizon 2020 for research and Technological development.
The E2VENT system that we will develop is an external thermal refurbishment solution with external cladding and air cavity (fig.1).
The distinctive feature of this system is the Smart Modular Heat Recovery Unit allowing us to recover energy from the extracted air while performing the air renewal using double flux heat exchanger in the air cavity (fig.2).
This way the E2VENT system enhances the energetic performance of the building and fresh air renewal does not decrease it. Aiming at providing a heat storage system for the reduction of peak of electricity consumption and/or for cooling in summer, a Latent Heat Thermal Energy Storage based on phase change materials properties may be implemented if needed (fig.3).
The proposed solution for building retrofitting should lead to 50% reduction of primary energy needsand significant CO2 emissions reduction. The main target of E2VENT system is the market associated to the retrofitting of multistorey residential buildings built in the 60’s 70’s.
Those buildings are found in all Europe and can be characterized by their insulation weakness, bad air quality due to the lack of air renewal system and low architectural interest.
Project duration: 1 January 2015 - 30 June 2018
