Software developers are constantly extending the boundaries by introducing new features into their programs to support the integrated workflow and invite different specialists to participate in the project on the early design stage. This contribution further expands the discussion about the most effective method to export the information whether by IFC or gbXML data model; with or without the assistance of additional plugins. Export of the simple geometry is tested within three BIM platforms: ArchiCAD, Allplan and Revit. The main focus of presented test runs is set on exporting the building materials data and its preservation in the IFC and gbXML for the further import to the thermal simulation tools. For the purpose of the present contribution the application and capabilities of Energy plus and Archiphysik are explored. As a conclusion, the guidelines and recommendations about the best workflow for each BIM platform are suggested, as well as the design for the “Customizer” application, which assists the mapping of the necessary data from IFC or gbXML to the IDF files usable to Archiphysik and Energy plus.

Software developers are constantly extending the boundaries by introducing new features into their programs, such as support for an integrated workflow, thus inviting different specialists to participate in the project at earlier design stages. These type of contributions highlight the importance of decisions concerning the most effective method to export information, invariant of the chosen data model, be it IFC or gbXML. Extensions to existing software are also considered, i.e. plugins. Export of simple geometries is tested within three BIM platforms: ArchiCAD, Allplan and Revit. The main focus of the presented test is exporting of the building materials data and its preservation in the IFC and gbXML format, specifically for import into thermal simulation tools. The application and capabilities of EnergyPlus and ArchiPHYSIK are explored. We summarize our results as a sequence at guidelines and recommendations suggesting optimal workflows for each BIM platform, as well as design for -Customizer-application, which assists in mapping of the needed data, on a per application basis, from IFC or gbXML to the IDF files usable to ArchiPHYSIK and EnergyPlus.

There are approaches to formulate it mathematically as the minimization of a discrepancy function between simulation and measurements. In these approaches, the discrepancy is usually defined based on the mean square error (MSE) between vectors of simulated and measured quantities. The MSE metric reflects the area between the corresponding curves, without accounting for the similarity of curve shapes. Thus, it may overestimate the discrepancy of quantities subject to strong variations, especially in the case of on/off behavior with hysteresis and phase shifts. The aim of this contribution is to investigate whether the MSE still represents an effective metric in such cases, and to examine the usefulness of an alternative metric. This alternative metric is based on dynamic time warping (DTW), which allows similar features to be matched with some distortion on the time axis. The question is ela...

However, building projects often suffer from deviations between planning and reality. In recent years, Building Information Modelling (BIM) has been extended to cover the whole building project life cycle, including the geometric modelling, collaboration mechanisms and building physics information. Although BIM enables the digitization of building planning and operation, the heterogeneity of supporting software, the different procedures of each company involved and the individuality of buildings themselves hinder a seamless collaboration between the parties, making it difficult to trace the impact of decisions. Adaptive Case Management (ACM) is a methodology to handle flexible business processes based on the achievement of business goals during case enactment, without defining strict process models. Therefore BIM management can take advantage of the ACM approach to support the accomplishment of bus...

However, building projects often suffer from deviations between planning and reality. Building Information Modeling (BIM) has lately been extended to cover the whole building project life cycle, but the heterogeneity of supporting software, the differing procedures of the companies involved, and buildings’ individuality hinder seamless collaboration among the parties, making it difficult to trace the impact of decisions on energy efficiency. (b) Action taken: Adaptive Case Management (ACM) is a methodology used to handle flexible business processes based on the achievement of business goals during a project, without defining strict process models. This chapter presents the first results of applying business architecture principles to ACM that uses domain-specific BIM tools for the content analysis that supports energy efficiency tracking throughout the project’s lifecycle. (c) Results achieved: Defining business actions and rules by using natural language patterns, along with the ontology entities (i.e., business concepts and their relationships), enable stakeholders to formalize a unique description of terms used and how they are related. This formalization is enacted with minimum IT involvement, which is covered by the initial system setup, leading to fully transparent project management. (d) Lessons learned: One of the first steps in the approach presented here is the formalization of the business information model by means of a business ontology that describes all business entities. We realized that business users with many years of experience require several iterations of reviewing the value streams to identify the entities involved in an unambiguous way. However, these multiple iterations were an essential benefit in achieving a common terminology.
