Volume content
The development of an interface, which links two building simulation tools to a test version of a product model is discussed.
SIMULAR AIR is a computer code for calculating the three dimensional transient indoor air flow using a k,e-turbulence model.
The developments in the computer-aided building design will enable designers to improve the energy performance in buildings, through a more appropriate design which will be better structured, will learn from previously accumulated knowledge (e.g.,
The technique of field modelling is applied to predict the indoor air movement and convective heat transfer induced by thermal sources in big enclosures.
The study is focussed on the sensibility of optimal start/stop control of hydronic heating systems on boiler and radiator sizing, supply temperature lift, and the building occupancy pattern.
Building design with a multi-discipline CAD system using object-oriented environment | 1991 | English
The aim of our paper is to present a multi-discipline CAD system named CONCEPTOR which allows the user to work during the various stages of the building engineering design.
We describe the need for a joint effort between design researchers and simulation tool developers in formulating procedures and standards for integrating simulation into the building design process.
SETIS is aiming at building a computer support for building thermal design. It deals both with the envelop of building and with its HVAC system.
The approach adopted by the Gaz de France Research Center for the modelling-simulation of building performance separates as far as possible modelling from simulation. Emphasis is placed on modelling and its validation.
A design tool for interior daylighting description of luminous enviroment with image synthesis | 1991 | English
As part of visualization of interior luminous environment in daylighting a programme (NATUREL) has been developed at CSTB. It allows to take into account complex shapes of building, furniture and apertures.
A numerical study of turbulent air flow in ventilated multi-room configurations, where both of buoyancy- and radiation-effects are of importance, is described in this paper.
The simulation of the transient behaviour of buildings is becoming more important as faster and cheaper computers reach the market. Many simulation programs and specialized tools have been developed to simulate complex situations.
A Statiscally-Based Hourly Weather Data Generator for Driving Energy Simulation and Equipment Design Software for Buildings | 1991 | English
This paper describes an operating hourly weather simulation model which is utilized to drive building energy simulation and equipment design software.
This paper discusses recent efforts to develop an intelligent front end (IFE) for a building energy simulation model using a readily available expert system shell.
A response-factor method for calculating coupled heat and moisture transfer in building | 1991 | English
Analytical solutions for coupled diffusion of heat and moisture through a material are used to develop a generalisation of the wellknown 2 x 2 matrix method for describing heat flow only.
An Educational Desing For Courseware Relating To Heating Load Calculations in Buildings | 1991 | English
Courseware is educational software, designed to create an instructional environment, for the purpose of facilitating learning.
The presentation of most HVAC simulation programs are out of date and batch processing type. Their use is complex and often requires a good data processing knowledge.
A first order correction to uni-directional heat transfer is proposed, so that multi-dimensional heat transfer effects can be accounted for with only a moderate increase in storage and CPU timerequirements.
Application of Simulation programs to the Assessment of Overhekating Rosks in Buildings and the of IEA Annex 21 | 1991 | English
This paper describes the objectives of International Energy Agency (IEA) Annex 21 and the ongoing work of Subtask B which deals with how programs should be used for particular applications.
