E2VENT

Energy Efficient Ventilated Facades for Optimal Adaptability and Heat Exchange enabling novel NZEB architectural concepts for the 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.
