Building thermal performance is an important factor in habitations, especially for those destined for people of low income. Buildings properly projected for the climate surrounding them provide comfort and save energy. The evaluation of a building's thermal performance includes a global picture of the architectural project in relation to the thermal exchanges between the built atmosphere and the external atmosphere, where the characterization of the local climatic conditions is one of the most important stages. Local values such as solar radiation schedules, temperature, and relative humidity of the air as well as predominant wind speed characterize the conditions of building exposure to the climate. With respect to thermal performance evaluation, the climatic data are characterized by typical project days for winter and summer periods. Such days are determined in function of its frequency of occurrence that represents levels of requirements in the evaluation. In this article a methodology is presented to estimate the typical days of the project, through statistical treatment of climatic data.
Keywords : climatic data; typical days of project; building thermal performance.
