Abstract

Sustainable building solutions, as well as building energy efficiency standards and calculation methods, often are related to climatic conditions in which the need for energy savings in winter prevails. In the case of Mediterranean climate areas the approach turns out to be more complex since the central aim is to find a balance between the need for energy-saving strategies in winter and summer. Moreover the sustainability-oriented building design privilege the use of local technologies and traditional materials which are often characterized by high thermal inertia and low thermal insulation. This study analyzes the performances, in terms of energy-efficiency and thermal comfort, of a residential building for self-sufficient elderly people, designed and realized according to building sustainable development criteria, located in Puglia, a region in the south of Italy. The performance evaluation of the passive systems that characterize this building needs the analysis of the dynamic thermal behaviour. To this purpose, the software TRNSYS has been used. It represents an extremely flexible calculation tool for management of the “Environment-Building-Equipment-User” system. TRNSYS has been coupled with CONTAMW in order to evaluate the effects of several ventilation strategies. The model of the building has been validated through field measurements in non-occupied conditions. The thermal behaviour and the thermal comfort performances of a typical residential unit have been compared with alternative solutions of building envelope usually adopted. The results underline the impact of thermal inertia for the energy efficiency of buildings in specific climatic conditions. The simulations allowed refinement of passive cooling ventilation strategies without any mechanical air-conditioning system. This solution has been evaluated through a critical comparison between Fanger's theory and adaptive thermal comfort model. Better performances are expected by using hybrid ventilation systems coupled with a “smart” control system.
