Estimation of the thermal loads on buildings with CAD systems support

摘要

The goal of this paper is the design and implementation of an algorithm for estimating thermal loads in a civil construction, in which the capture geometric information of the architectural plan of a building created in a CAD system (Computer Aided Design), and the calculation of thermal loads in the spaces of the building are integrated. The algorithm was implemented in a software tool that comprises two modules, the first for obtaining geometric information of the building, developed in language AutoLISP programming and the second, in which the calculation of the thermal loads is performed by the method of Radiantes in Time Series (RTS), implemented in Visual Basic for Applications (VBA) in AutoCAD. In this paper, the advantages of integration of both modules, is based on the same graphical environment, to estimate the thermal loads to be removed from a building, and the potential of the application of the RTS method for estimating thermal loads on the other methods, are expressed.
