We consider a strictly three-dimensional modeling technique as a basis for numerical simulations. Applications range from
Computational Fluid Dynamics (CFD) software is increasingly being used to predict the effects of wind on buildings and on the people in and around them.
This paper draws the attention to the importance of a correct modelling of the inlet temperature of naturally and mechanically ventilated multiple-skin facades.
Shape factor calculation and visualization for the influence of the thermal enviroment on the human body | 2003 | English
The purpose of this paper is to explain the indoor thermal radiation environment of the human body in detail. Using a 3-D human body model, shape factor calculations between a human body and surroundings are executed.
Skyvision: a software tool to calculate the optical characteristics and daylighting performance of skylights | 2003 | English
Skylights can offer useful benefits in reducing building energy consumption and improving building occupants satisfaction.
Predicting human geometry-related factors for detailed radiation analysis in indoor spaces | 2003 | English
In this study, formulae for predicting projected area factors and view factors of individual body parts of standing and sedentary humans for detailed radiation analysis were developed.
HVAC systems that supply both space heating and domestic hot water are becoming more popular in residential buildings In North America.
The hygrothermal behavior of rooms: combining thermal building simulation and hygrothermal envelope calculation | 2003 | English
The hygrothermal behavior of a building component exposed to weather is an important aspect of the overall performance of a building.
Numerical simulation on the prevention effect of the cold draft along the window in wintertime | 2003 | English
This study is aimed to contribute to energy saving and to achieve the indoor thermal comfort by preventing the down draft along the window in building with less heating energy than the common equipment, e.g. FCU.
Room air conditioners: determination of empirical corelations for predicting building energy consumption | 2003 | English
Two room air conditioners were modeled in order to predict the total cooling capacity, the sensible cooling capacity and the Energy Efficiency Ratio (E.E.R.) of each appliance.
This paper describes the application of a building simulation program to construct a decision-support tool for use by policy makers addressing the needs of the Scottish domestic housing sector.
This paper describes a performance-based evolution model using GA as the evolution algorithm and CFD as the evaluation mechanism.
The barriers to simulation deployment in design practice are well documented.
The purpose of this research is to develope a simplified method to predict the relationship between the design of architecture envelope and the air- conditioning load in Taiwan.
The aim of the presented work is to refine the ESP-r system by incorporating phase change materials (PCM) modelling. The behaviour of PCMs is modelled using ESP-r’s special materials facility.
Radiant heating and cooling, including building component embedded systems, have become a common heating and/or cooling technology in the recent few years.
Hourly energy simulation was used in combination with a life cycle assessment framework to model the environmental effects of energy consumption in buildings.
A study by Reinhart and Herkel showed term predictions of daylight availability in architectural spaces should take the conditions of all individual time steps into account.
The performances of air conditioning equipments, like heat pumps, chillers or air conditioners, derive not only from the operative thermal levels, but also from the building requirement trend which normally involves frequent reductions of t
