A method to estimate the shading of solar radiation theory and implementation in a computer program | 1999 | English
A general method to determine the shading of direct and diffuse radiation is presented. This can handle an almost infinite number building surfaces and screens of any shape.
A study on the applicability of the time-division hot water supply heating for ondol: the radiant floor heating system in korea | 1999 | English
The typical Korean residential buildings, especially apartment buildings, are furnished with ONDOL – the Korean traditional radiant floor heating system. The buildings are getting more insulated and air tight for heating in hard winter.
Bringing simulation to application: some guidelines and practical recommendations issued from IEA-BCS annex 30 | 1999 | English
Simulation tools are not yet used as much and as well as they should all along building life cycle ( BLC ). Most important decisions are still taken almost without using these tools.
A practical example of the CHAT_D software application for predicting the risk of thermal disconfort in a house equipped with a cooling floor | 1999 | English
The CHAT-D software environment was developed by the Electricity Applications in the Residential and Commercial Buildings Branch, of the research and development division of EDF (Electricité de France). Our main objective is to ensure the well-bei
An evaluative method for high-perfomance window system and window side radiation environment | 1999 | English
A study was performed on a method to evaluate performance of window system necessary to satisfactorily maintain the window side radiation environment in a glass building.
Comparison of reproducibility of a real cav system by dynamic simulation HVACSIM+ and TRNSYS | 1999 | English
It is necessary to use the dynamic simulation program to evaluate the dynamic characteristic of the HVAC system.
A method for analysis of controllability of duct systems designed for variable ventilation flow rates | 1999 | English
This paper presents a tool, based on a method using IDA for simulation of duct systems and MATLAB as a pre- and post-processor, to study the controllability of VAV-systems.
A study of the simulation of the visibility of baseballs flying in the dome stadium | 1999 | English
An evaluation system of the visibility of a ball flying is indispensable for the best architectural design and artificial lighting design of a baseball dome stadium, as it is essential to create a suitable visual environment for both players and s
The premise underlying this work is that introducing uncertainty considerations into simulation will facilitate risk assessment and that this, in turn, will help to improve designer confidence in simulation. Sources of uncertainty abound in buildi
A nodal model for displacement ventilation and chilled ceiling systems in office spaces | 1999 | English
A nodal model has been developed to represent room heat transfer in displacement ventilation and chilled ceiling systems.
An analysis of the fresh air load reduction system by using underground double floor space for air conditioning | 1999 | English
This paper presents a feasibility study of a fresh air load reduction system by using an underground double floor space. The system was introduced into a real building (Aichi Children’s Center in Japan) and was examined by the field measurement.
A two-dimensional numerical simulation of airflow around bluff bodies is presented in this study. The two turbulence models, i.e., standard k-e model and RNG k-e model, are employed to predict the flowfield and wind effects on bluff bodies.
A controller for HVAC systems with fault detection capabilities based on simulation models | 1999 | English
This paper describes a control scheme with fault detection capabilities suitable for application to HVAC systems.
A study of the of performance-based simulation tools for building design and evaluation in Singapore | 1999 | English
This paper provides an overview of the usage of performance-based simulation tools for building design and evaluation in Singapore based on an extensive industry survey.
Application of complex energy simulation in competition design of Czech embassy en Ottawa | 1999 | English
This paper describes use of building energy performance modelling and simulation in design process at the early conceptual level of architectural design.
Traditional algorithms for the simulation of sound propagation in spatial enclosures include the image source method and the ray-tracing method. These algorithms are computation intensive and take a long time to generate results.
In multizone models used to predict thermal comportment of buildings and inside air quality, representation of the airflow through large vertical openings is very important.
This paper presents the preliminary modelling perspectives of an ongoing project where a exible simulation tool for component and system analysis of district heating consumer installations is developed. The simulation tool makes it possible to sim
