Abstract

In this thesis, BIM is examined as part of the integral planning methodology. Specifically, the BIM goal in this thesis is to develop the thermal-energy simulation of HVAC systems using the harmonized Information Delivery Manual (IDM) and Model View Definition (MVD) method, using various application examples. Based thereon, the requirements for a given software architecture are derived and several data models are interconnected. The connection of the different data models is accomplished via specially defined transformation logics. The approaches based on the object and data level allow the definition of the associated Level of Development (LOD)s. Through these extensive elaborations future tools and methods can be established and tailored according to practical requirements. With the development of an IDM, the goal-oriented modeling is described component by component. In the first step, the user level and the technical level are initially considered separately, but in thesecond step they are considered holistically . At the user level, a process diagram is defined from the perspective of management, coordinators, and modelers. While creating the process diagram, the individual tasks, the sequence of execution, and their interfaces are identified. Within the interfaces, the data and information needed for the exchange is specified. This preliminary work allows the definition of a data exchange requirement model at the technical level. Such a model records not only the method of transmission, but also the type of data and information subject to exchange in the respective interfaces.After this formalization, a MVD will be developed. The purpose of the MVD is to tailor the individual interfaces for future applications. The IDM, in particular the process diagram and the data exchange requirements model, form the basis for the definition of the LODs. The LODs define the coordination of the model versions to be delivered during the course of the collaboration on the building project. The specification of the period-related degrees of each model’s maturity allows the coordination of the project. A loss-free transfer in the different interfaces requires a further specification of the transformation of the data and information in the course of the generated output. For this purpose, the relationship structure of the individual models is examined and a method for the transformationof the different data is presented. The methods and results presented in this thesis were elaborated and examined during the course of the EnEff: BIM research project. This research project, funded by the Federal Ministry for Economic Affairs and Energy, was carried out from the end of 2013 to November 2016 and bears the title:ËnEff: BIM planning and operational optimization of energy-efficient buildings through building information models", with the funding code: 03ET1177A-F. To channel further international activities, this project was bundled and edited together with an international research consortium in the IEA EBC Annex 60: "New generation of computational tools for building and community energy systems based on the Modelica and Functional Mockup Interface standards"coordinated by the Energy and Buildings Communities Program.
