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
Testing the energy simulation building model of Consoclim using bestest method and experimental data | 2003 | English
Consoclim is a building energy simulation software package which aims to simplify the input data. The building is modelled by only one capacity and five resistances.
Since buildings have a predominant impact on the global climate change and other environmental issues, it has become necessary to consider environmental performance in building design.
Preliminary study on an estimation method for annual solar irradiance at varius geographial altutudes | 2003 | English
A preliminary investigation is made into the global variation in irradiance under the Clear, the Intermediate (partly cloudy) and the Overcast sky conditions (Nakamura et. al., 1986, 1987).
This paper presents a simulation study employed for the optimization of the building envelope for a new university building located in Montreal (latitude 450N).
This paper describes modelling and simulation of a space with radiant cooling ceiling (CC). The computer model represents a test chamber, which is located in a laboratory of the Department of Environmental Engineering in Prague.
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.
This article presents a one-dimensional model of spray vaporization that can be easily used in thermal performance simulations of buildings.
This paper draws the attention to the importance of a correct modelling of the inlet temperature of naturally and mechanically ventilated multiple-skin facades.
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.
Simulation and evaluation of markets for building cooling heating and power applications in the U.S. | 2003 | English
A two-level analysis was used to study the economic potential of implementing Building Cooling, Heating and Power (BCHP) technologies in the U.S.
The lightswich wizard: reliable daylight simulations for initial design investigation | 2003 | English
A web-based, non-expert daylighting analysis tool has been developed to support daylighting-related design decisions in peripheral private offices during an early design stage.
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.
The sky view factor indicates the relationship between the visible area of the sky and the area covered by urban structures.
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.
This paper describes a performance-based evolution model using GA as the evolution algorithm and CFD as the evaluation mechanism.
A computer-model is used to simulate the evacuation of the occupants in a building.
Embedded generation has been described as a “paradigm shift” in the way in which electricity is produced, with the focus of power production shifting away from large centralised generation plants to production of heat and power close
Radiant heating and cooling, including building component embedded systems, have become a common heating and/or cooling technology in the recent few years.
