Modeling and accuracy of sound field analysis by finite element method on building environments | 1999 | English
Numerical simulation on simultaneous control process of indoor air temperature and of indoor air temperature and humidity | 1999 | English
In order to evaluate the air conditioning system performance in terms of control, comfort and energy conservation, this paper presents an approach to modeling automatic control process in a typical conditioned space of an office building.
A method for evaluating solar rights and shading requirements in an urban environment is presented. The method is embedded in a CAD tool developed and adapted for this purpose.
It is important to apply the natural light effectively for the low energy consuming daylighting design.
New experimental validation and model improvement tools for the Clim2000 energy simulation software program | 1999 | English
This work has allowed to test different model improvement tools, by applying them on two building models. At the close of this study, an important point concerning the capability of the CLIM2000 software program to perform exact derivative
Study on adaptive mesh generation method in CFD calculation with conjugate heat transfer model | 1999 | English
In order to make proper radiative meshes with considering thermal distribution on solid surfaces, we inves- tigated the adaptive mesh generation method and per- formed parametric survey for a threshold which con- trols subdivision of mesh.
The purpose of this study is designing a hybrid system which is a combination of radiant cooling and low temperature air conditioning integrated with ice stor- age system.
Load prediction for aptimal thermal storage: comparison of three kinds of model application | 1999 | English
It is necessary to predict the load of the following day and hours to establish optimal thermal storage.
The Simulation Problem Analysis and Research Kernel (SPARK) uses graph-theoretic techniques to match equations to variables and build computational graphs, yielding solution sequences indicated by needed data flow.
This article presents the SIM-FAST software : it is a tool which allows to evaluate the energy consumption and the financial cost of French buildings in the Residential sector.
Simulation of ventilation and indoor air quality in houses using average japanese daily schedule | 1999 | English
In order to explain the effect of ventilation systems and airtight performance of houses in detached houses, the investigation was made on a simulation program which calculates the ventilation rates and indoor air quality.
In this article, we present the dynamic modelling of a heating and air conditioning small output installation in a residential building. The main aim of this modelling study is to acquire a better knowledge of all phenomena which govern the behavi
Based on K- two equation turbulence model, we used PHOENICS 1.4 and numerically simulated air distribution and contamination field under different conditions in a vector- flow clean room.
The operation of technical building devices demands a lot of heating, cooling and electric energy. This also causes monetary costs and pollutant emission as well.
In this paper a new method called TSM was presented to analyze wind effect on high-density building areas. With TSM, a software named WEATHER is developed based on STACH-3.
This paper proposes useful techniques of regression analysis to estimate regional water temperatures for the optimum design of the hot water supply system.
Simulation of cleaning is a new area in building simulations. To make rational cleaning is it important to know how difficult it is to clean rooms. I define a Cleaning Index (CI) as the cleaning area divided by the floor area.
A model for the design of urban grids and fabric with solar rights consideration taken into account is presented.
The optimal supervisory control strategy for a central chilled water facility has been determined. A quadratic linear regression relation for the total system power in terms of the controlled and uncontrolled variables was developed using simula
Numerical analysis of air temperature increases in urban area using the building-urban-soil simultaneous simulation model | 1999 | English
The authors propose a predicting methodology combined with simultaneous solution for Building- Urban-Soil system to analyze the heat island phenomenon quantitatively in this paper. Using this model, numerical simulation is performed in order
