Thermal evaluation of a ventilated building using dynamic simulations

摘要

A thermal analysis of ventilated office building was performed by the use of a dynamic simulation software. This work focuses on the analysis of a ventilation strategy, contribution to the thermal performance of a 2000 m~2 building. The studied building is located in a region within the BSlkw climate according to the Koppen climate classification. In this climate, commonly referred as steppe, both air cooling and heating is needed in order to provide a satisfactory thermal comfort condition throughout the year. Within this weather it is possible to incorporate several energy saving strategies so the heat gains and losses can be calculated. The analysis starts with the incorporation of basic bioclimatic notions and the selection of commonly used construction and glazing materials. Several energy saving strategies were established; this strategies, such as the study of different materials and natural ventilation during the warm season. The results show hourly mean temperatures and energetic demands due air conditioning during the course of a year.
