摘要

The objective of this project was to test the use of object oriented data structuring methods (building product models) as a means of integrating CAD applications and dimensioning software for HVAC design. The application area of the prototype developed in the project was the design and dimensioning of a radiator network. The project was part of the Finnish ETRR research program (Energy-efficient buildings and building components). The project also participated in the COMBINE project (Computer Models for the Building Industry in Europe), which was part of the large EC-funded JOULE program. The objective of the EC's COMBINE project was to develop the computer-aided energy economic and HVAC design of buildings. In the first phase of COMBINE six separate prototype applications from different countries were integrated through an aspect product model for energy-conscious building design. This product model was formalized using the EXPRESS data definition language, which has been developed and used within the international STEP standardization work on product data The data exchange between the six applications was carried out in the form of STEP physical files. Data definition and data exchange methods of the international STEP standardization work and the national OOCAD project were tested with the prototype application. The internal data exchange was handled using a data exchange format developed earlier in the OOCAD project at VTT (the OXF-format). The CAD (Auto CAD) module of the OOCAD was also utilized. For communication with the other applications the OXF-files were converted to STEP-files and vice versa
