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.
