Currently used design tools for kitchen design are often complicated, have poor interfaces and limited capabilities to exchange data between different applications. No integrated kitchen design environment is available although kitchen design requires the expertise of many different specialists and the decisions of various designers strongly affect each other. The complex design, build, maintain and retrofit process has been mapped in order to provide a logical structure and flow for the kitchen design system.
This paper reports on two case studies that explore the current use of computational tools in building design scenarios. Goal of the project is to gain insight into the role of tools in the design process and to investigate and capture the designer’s viewpoint concerning building simulation. This viewpoint is essential for a successful application of simulation in the design process, but might differ from the viewpoint of the developer of simulation tools.
Eight mechanically ventilated flow patterns have been conducted in a test chamber. The air age in test chamber is measured with tracer gas technique. A CFD program named as STACH-3 is developed with the transport equation of air age in it. The predicted air age with STACH-3 is compared with the experimental results. It is shown that the computed air age agrees well with the experimental results except a few points. The relationship between flow pattern and air age distribution for the test chamber is analyzed with not only the predicted but also the experimental results.
This paper describes the methodology and the implementation of DEST, which is a simulation software developed to help the designer during design process. For each design phase, DEST provides corresponding method and program. Some new ideas about using simulation in design are introduced in the paper, with some examples that come from real projects. It is believed that the HVAC design should shift from single-point-design to whole process design in the new century. To achieve this goal, simulation plays an important role.
For improving feedback about thermal simulation results from engineers to architects, it is desirable to present them in the three-dimensional context of the building. In this paper, we present a system for improved thermal simulation and interactive 3D visualisation of the results. We describe extensions of the physically-based rendering system GENESIS-2 towards
Many recent, moisture-originated failures in low-rise residential and high-rise residential/commercial buildings have put a significant pressure to change construction codes in North America and Europe. However, solutions to moisture induced problems may be difficult when several interacting mechanisms of moisture transport are present. Recently, a new approach to building envelope durability assessment has been introduced in North America.
One central idea of building simulation is to visualize calculated datavalues embedded in an in herently three dimensional building shape. Here we present the interactive extensible program rshow which provides a compact and expansible interface for displaying scalar data in a D visu alization Design implementation and examples are discussed
In the framework of a collaboration between EDF and CSTB, we carried out a specific experimental protocol in Bouin house (CSTB site, house completely dedicated for infiltration and air change measurement) with different configurations to study the wind fluctuations. These experimental data are used to validate the pressure elementary models available into CLIM2000 software and especially the infiltration models. The agreement between experimental data and simulated results is acceptable taking into account the difficulty of this kind of experiment.
Interoperability among software tools that are used in building design can make the use of building energy simulation tools more frequent and more effective. Industry Foundation Classes (IFC) are an object- oriented data model of buildings that provides an environment for such interoperability.
