This paper is focused on the development of measuring equipment of Effective Leakage Area (ELA) by AC pressurization method. The formula to design the measuring system is derived according to the governing equation of the leakage, e.g.
A method to edit movies for a visual simulator and the of the torsional motion of high-rise buildings on human perception | 1999 | English
A study of the way in which humans visually perceive the motion of high-rise buildings was carried out. In our experiment, an edited movie was projected so that the subjects could observe the motion of the view from a window.
Several features of heat transfer on enclosing surfaces is discussed including temperature distributions in a room heated by a floor heater.
This paper concerns reasons - and solutions – for the time lag in the uptake and use of building simulation in the Czech Republic relative to many other countries. Following a brief introduction, several barriers to the use of simulation are ident
A potentially fast, flexible and accurate earth-contact heat transfer simulation method | 1999 | English
It is a basic premise of this paper that accurate earthcontact simulation is important and that the rapid parametric analysis of a structure can help designers pinpoint critical aspects of a structure early in the design stage.
An evaluation of radiance based simulations of annual indoor illuminance distributions due to daylight | 1999 | English
This paper presents a new, accelerated method based on GD\OLJKWFRHIILFLHQWV according to Tregenza [1] to calculate cumulative annual indoor illuminance distributions.
Comparison between wave theory and energy method in acoustic prediction of HVAC duct networks | 1999 | English
Sound predictions based on the wave theory were carried out on HVAC duct networks.
The objective of this study is to improve the control performance of Ondol heating system in apartment buildings. For this purpose, prevalent control systems and relevant researches are evaluated.
Assessing the value of typical meterological years built from observed and from synthetic data for building thermal simulation | 1999 | English
Typical Meteorological Years obtained from observed meteorological records have become the de facto data source when evaluating thermal performance of buildings.
Large Eddy Simulation (LES) with a Dynamic Subgrid-scale Model (DSM) is a powerful tool to predict indoor airflow. However, the model needs to average the model coefficient over a homogeneous direction.
An absorption chiller model is developed for HVACSIM+(J). The model simulates dynamic characteristics of the chiller, such as dynamic trends of chiller temperatures and COP.
Calibration procedure of energy performance simulation model for a commercial building | 1999 | English
Calibration with actual data has been considered as one of the most important and difficult part for the systematic energy audit procedure.
A comprehensive approach to modeling and evaluating the visual environment in buildings | 1999 | English
This paper describes the development, implementation, and evaluation of a computational tool for the comprehensive support of the lighting design process.
Within the research context relating to the modeling process of architectural buildings and landscape planning, the CRAI particularly works on the simulation of day-light and artificial illumination. The purpose of this research is to develop a so
Analysis on coupled heat and water transfer through porous materials by thermodynamic energy | 1999 | English
New thermodynamic energy “water potential” based on the chemical potential of a component of mixture gases is defined as the driving force of gaseous phase water flux.
Coupling between a graphical simulation environment simulator and an optimisation algorithm | 1999 | English
The main aim of this study is to derive some simple rules for an optimal management of direct electric heating in residential buildings. Optimal management should minimise the running cost of heating while maintaining comfort, in the case of contr
A modular: loop-based approach to HVAC energy simulation and its implementation in EnergyPlus | 1999 | English
This paper presents the new EnergyPlus HVAC simulation environment, which differs from existing energy analysis programs in three key respects.
We developed a PC-software to estimate thermal environment of a residential house. To make the software practical for non-technical people, the easiness of operation was our main interest in this development.
