E2VENT

Energy Efficient Ventilated Facades for Optimal Adaptability and Heat Exchange enabling novel NZEB architectural concepts for the refurbishment of existing buildings

The E2VENT system is an external refurbishment solution with external cladding and air cavity that embeds different breakthrough technologies ensure its high efficiency. The distinctive feature of this system is the Smart Modular Heat Recovery Unit (SMHRU) allowing us to recover energy from the extracted air while performing the air renewal using double flux heat exchanger in the air cavity. 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 (LHTES) based on phase change materials properties may be implemented if needed.

The main goal of E²VENT project is the development of an energy efficient ventilated façade retrofitting system designed for an optimal and adaptable refurbishment of existing buildings.


Abstract

The old buildings, which represents the vast majority of the building stock, are predominantly of low energy performance and subsequently in need of refurbishment work. Within the existing European building stock, a large share (approximately 34%) of the suburban multi-storey residential building stock is built in the 60’s 70’s, when there were only few or no requirements for energy efficiency. Those buildings are characterized by a high energy consumption, bad air quality due to the lack of air renewal motorized system, poor aesthetics and need for maintenance.

E2VENT develops, demonstrates and validates 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, including:

  • Smart modular heat recovery unit which improves Indoor Air Quality while minimizing energy losses;
  • A latent system using PCM that allows thermal storage mode for the reduction of energy peaks;
  • Cost-effective, easy to install, high performance adapted products for external thermal insulation;
  • Smart building management system enhancing the user experience and allowing future adaptability.

The developed technologies will be integrated in the ventilated facade, and a real time intelligent façade management system will control operation of the system based on meteorological prediction methods for forecasting in advance the decentralised electricity production and the energy (electrical and thermal) demand of the building enabling maximum RE usage. It will inter-operate with existing or latest state-of-the-art Building Energy Management System, to achieve optimum energy efficiency by reducing primary energy needs, CO2 emissions and peak loads, assuring at least the same comfort levels required by Member States Building Codes, at an affordable price.
