Elval Colour with etalbond® participates in E2VENT project

Elval Colour, with etalbond®FR, is a partner for the building envelope section in the research project E2VENT.

A primary value of Elval Colour is the relentlessly understanding of products and disseminate the knowledge generated across all functions in order to continuously improve. Continuous R&D on various fields allows the monitoring of the evolution of technology, quality and environmental standards.

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.

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. 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 parts of the E2VENT system are:

  • A Smart Modular Heat Recovery Unit (SMHRU), which renews the air and simultaneously allows for the heat recovery from the extracted air.
  • A Latent Heat Thermal Energy Storage (LHTES), which is a heat storage system implementing phase change materials. Elval Colour is the manufacturer of the enclosure of the SMHRU and LHTES units, using etalbond®.
  • A smart management controlling the system for optimal results
  • An anchoring system of the cladding system, that limits thermal bridges. The material used for the cladding system is etalbond®.


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.
