Residential Retrofit assessment platform and demonstrations for near zero energy and CO2 emissions with optimum coST, health, comfort and environmental quality.
ReCO2ST demo sites’ news


Demo site description: The demonstration site in London is located in Uxbridge, West London and consists of a four storey apartment block with 23 apartments. Pre-monitoring was carried out and various technologies have been installed since the project initiated. Retrofit measures were applied including 20m2 of Vacuum Insulation Panels (VIPs), smart windows, PV panels of 4kWp in total, Concentrating PVs (CPVs), innovative HVAC with mechanical ventilation and Phase Change Material (PCM) storage, cool materials and nature based solutions (1 cassette unit and 1 aeroplant unit).

Demo site in Uxbridge, London

Latest update: Post-monitoring was carried out between September 2019 and June 2021 in one apartment. Electric meters were installed to measure the performance of the PVs, CPVs and consumption at various points. Temperature, relative humidity (RH) and CO2 measurements were conducted to evaluate the effectiveness of the cool materials, VIPs, smart window and phase mechanical ventilator with PCM. Furthermore, users’ feedback were sought on the acceptability of the technologies. The next phase concerns the evaluation of the performance of the ReCO2ST technologies based on energy, environmental and economic criteria as well as comfort.


Demo site description: The demonstration site in Vevey, consists of a typical 15 apartments building situated in an old district of the city of Vevey, near Lausanne. Pre-monitoring was carried out followed by renovation works including regular exterior and interior renovations as well as the installation of smart windows, 20kWp of PV panels, 1 CPV unit and 1 aeroplant unit.

Latest update: Post-monitoring took place from October 2019 and will go on until December 2021 to gather data on electricity consumption and production, heating consumption, DHW energy consumption, indoor temperature, CO2 and humidity. Results are being evaluated versus Key Performance Indicators (KPIs) related to economics, energy efficiency, environmental performance, health and comfort.


Demo site description: Demo site description: The demo site located in the southern coast of Cadiz in Spain, is a social housing residential 28-apartment block of four floors in total. Initially, major structural renovations took place including the insulation of external walls, replacement of windows, installation of window shading devices and installation of solar thermal panels and heat pumps for DHW. As part of the project, various technologies, were also installed comprising of VIPs, PVs, CPVs, HVAC systems with evaporative cooling, a Cooling Evaporative and Ventilated Facade (CEVF), 1 aeroplant unit and an intelligent energy management system (IEMS).

Latest update: The post-monitoring phase is expected to start this month (July 2021) and will be carried out in 6 apartments (2 in each floor, to account for north and south orientation) to capture measurements of RH, indoor temperature, CO2 and VOC. The functionality of the IEMS will be tested to explore optimal systems’ operation.


Demo site description: The demo site in Frederikshavn is a three storey social housing apartment block with 58 apartments located in the area of Munkeparken in Denmark. Pre-monitoring took place from November 2020 until May 2021.
