Abstract
Design heating, ventilation and air conditioning (HVAC) standards as ASHRAE and ANBT NBR 16401 supply only one climatic data for almost all cities listed, collected from meteorological stations located in the airports. In Rio de Janeiro, both airports are located next to the sea. It is well known that urban areas are characterized by different microclimates and the formation of heat islands, with an increase in air temperature compared to the areas of low occupancy or rural. As soon as the cost of automated meteorological stations have decreased, more suitable climatic data have become available. On the other hand, HVAC designer use commercial software for thermal load calculation where it is comfortable to pre-select climatic data ready available, usually that mentioned in the design standards. This paper aims at evaluating the effect of using meteorological data from the Santos Dumont Airport instead of the closest climatic data on the thermal load calculation of a building placed in São Cristóvão neighborhood. After choosing the design criteria and calculating the typical design day the differences in the termal load results were analyzed.
