Abstract text:
This study analyzes a single-family dwelling, from the energy performance point of view. The concept of the housing model took into consideration aspects related to a high degree of layout flexibility, high-energy performance, minimal impact on the environment and feasible financial investments. The analysis consists of an estimated energy performance using direct methods and numerical simulations for thermo-energetic behavior. The evaluation using direct methods places the model as an A class energy performance building. Furthermore, an assessment for the energy performance was conducted and revealed values related to specific energy consumption for heating, domestic hot water, lighting and CO2 emissions. Results from numerical simulations highlight that total glazing area of the building's envelope is considerable when estimating the overall heat loss balance. At the same time, the judicious orientation of the glazed areas contributes to the reduction of the heating energy demand from non-renewable resources by taking advantage of the solar gains. Conclusions of this study highlights aspects related to specific annual energy consumption, feasibility and efficiency of passive solar energy recovery systems integrated in the building's architecture.
