12/21/09 : Performance project - Large scale monitoring of demand controlled MEV in occupied housing
Applied on two new buildings erected in 2007 located in Paris and near Lyon (France), Performance project has given the opportunity to measure precisely, in a large set of dwellings, the efficiency of the French standard ventilation system (humidity controlled Mechanical Exhaust Ventilation) in general, of the Aereco DCV system in particular. After an assessment of the performance of the installation (envelop, ductwork and airflows), a total of 30 occupied dwellings has been monitored during two years since November 2007 to measure representative parameters for energy consumption and indoor air quality.
The monitoring has enabled to better understand the parameters which can influence the ventilation performance. The results have demonstrated the efficiency of the humidity controlled ventilation in managing the indoor air quality by measuring CO2 and humidity concentrations. Energy savings on the equivalent airflow for energy have been evaluated at 30% on the over-occupied monitored dwellings but the extrapolation to the average occupancy of the French building stock have shown to be around 55% energy savings, which is consistent with the theoretical calculation of the CSTB technical approvals.
