There is a need for Dutch design support tools for building services that can be used in early design stages. TNO Building and Construction Research has therefore initiated the research project described here. The project will result in guidelines for design support tools for early design of building services in the Netherlands. These tools should make it possible to quickly compare alternative conceptual design solutions and to visualize possible consequences of the underlying design decisions.
Recent advances in mathematical models, computer processors and OOP compilers have been motivating the development of the Domus program for whole-building hygrothermal simulation. The Domus program for simulation of multi-zone buildings has been developed in c++ language under C++ Builder environment, which is a fast and precise easy-to-use compiler. The program is available on the PC platform under Windows 9x and NT operating systems. The user interface consists of a series of windows in which the user can enter the relevant input data and review the results.
In the context of a european project dealing with the issue of transport safety improvement in fog conditions, an experimental building has been constructed on the FUL campus, in the southern part of Belgium.
DIAL-Europe is the final product of a three year European project that ended in March 2003. During this project the “Swiss” tool LesoDIAL, developed during the IEA task 21 in 1999, has been expanded with, among other items, an artificial lighting module. The objective of this module is to support artificial lighting design for architects in the early design stage.
This paper describes a simulation model for predicting end-use energy in residential sectors of a city or region. In this model, the annual energy consumption of a dwelling is simulated from the occupants’ schedule of living activities, weather data and energy efficiencies of appliances and dwellings. By summing up the simulation results for various household categories, total energy consumption for the residential sector in a region can be estimated. In this paper, the energy consumption for Osaka City is simulated by this model. The result is compared with statistical data.
This paper presents a district energy system simulation model in which the energy flow of a district is modeled as the sum of total energy flow in each building. By using this model, various kinds of energy supply systems can be evaluated taking into account the relationship among performance of energy supply systems, available technologies, and conditions of targeted districts, such as characteristics of energy demand, size and arrangement of buildings.
A set of geometry translation tools and capabilities have been developed to increase base efficiencies in the simulation of both the internal and external environment of buildings. The tools allows us to build a 3D model in one package and then translate the geometry for use in a number of other simulation packages that we use. Though not a unique concept, it does allow the use of preferred software for undertaking the building of the 3D model.
The computer software AUSSSM TOOL, originating from the methodology of the revised-Architectural- Urban-Soil-Simultaneous Simulation Model (revised-AUSSSM), was developed by adopting the Graphical User Interface (GUI) features to support users, who can use the interactive computer display for parameter settings, simulating, visualizing, and reporting the numerical calculation results instead of complicated programming. The purpose of the AUSSSM TOOL is to determine quantitative parameters such as air temperature, exhaustive heat from air conditioning systems, energy heat balance, etc.
With the advancement of technology, and with the widespread availability of simulation tools, we are forced to consider which simulation tool would be appropriate for a particular problem. The seemingly trivial decision is in reality not very easy to make. And this leads to the practice of using the most sophisticated tool available for every problem. The levels of resolution and complexity are directly related to the accuracy of the simulation and to the total cost of the simulation process. A simple tool may be cheaper, but there is a high risk of inaccuracy.
People that work in office buildings have new needs in terms of comfort within their work place. We suggest to develop a multicriteria office cell façade, allowing to control luminous, thermal and airflow parameters. It will be controlled to offer global comfort to the office cells occupants.
