Changing working processes not only in manufacturing and assembly but also in office work require advanced buildings which allow a maximum of flexibility towards building structure and all its services (HVAC, telecommunications etc.). To gether with the growing importance of shared tenant services in intelligent buildings, theattempt to reach low-energy consuming buildings despite of their required flexibility in supplying a good infrastructure leads to a growing importance of "building performance".
The high thermal insulation of housing construction has been spreading all over Japan, for the improvement of indoor environment and the efficiency of energy consumption. From the view point of global warming, it is acknowledged that the high thermal insulation reduces CO2 emission in the heating and cooling phase, but it increases CO2 emission at construction phase since the amount of materials for thermal insulation increases.
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
