A Brief Introduction to Building Information Modeling (BIM) and its interoperability with TRNSYS

Abstract

Hand-drafted print, sketching and hand modeling were the standard for building designs before the advent of computer aided design (CAD) systems. Nowadays CAD systems are better understood, their adoption increased until the 2D, 3D CAD system and the virtual reality system have become the norm. Their natural evolution has given rise to a new and more complex generation of building design tools known as building information modeling, or BIM. There is insufficient clarity about what BIM is, although this is improving, and there is much shared understanding. There is agreement that BIM is not just software. BIM is not just CAD, or geometric data. BIM is a collaboratively generated and maintained data rich information source for the life of the design process and beyond. In this paper, we present briefly the greatest value derived from BIM in the use and maintenance of buildings and the use of TRNSYS with BIM.
