Monitoring of CasaNova Low Energy District: Result and Discussion

Monitoring results showed that the buildings have total primary energy consumptions very different from each other (ranging from 79 kWh/m2y to 172 kWh/m2y), and with a meaningful gap compared with the predicted ones, as calculated in the design phase, reaching in some cases values more than double (+167%). According to EURAC evaluation, the main cause of this issue has been identified in tenants' behavior, especially on their non-optimal use and maintenance of the building and facilities. The paper shows how the buildings with simpler constructive solutions consume less energy than the complex ones. This difference, is mainly due to the difficulties encountered by the tenants on managing complex technologies in their flat, especially on mechanical ventilation. Indeed, the implementation of these technologies requires behavioral changes on those lodgers accustomed to live in the “classic” Italian house.
