This paper describes the modelling and simulation work that was carried out to support the design team of the new "Indonesian Jungle" pavilion in Prague Zoo.
The eXtensible Markup Language (XML) has recently become the W3C Standard for commu nicating data over the Internet.
In object based models, conversion becomes necessary when there is a mismatch among the representations of same physical quantity at the ports of different objects that need to be connected.
The paper is focused on the application of the simulation in the field of the space heating systems, based on the infrared radiant heaters. In the first part is preview of different sw packages.
Direct building energy simulation based on large Eddy techniques and Lattice Boltzmann methods | 2001 | English
The modeling of convective flows with 3D lattice Boltzmann fluid dynamics is presented using a lattice BGK approach for low Mach number flows with variable density combined with a large eddy turbulence model.
We present an advanced formulation of zonal models for calculating indoor air temperature and flow distributions in buildings. Our modeling is based on modularity:
Daylighting systems for the tropics example of laser cut panels (Austrália) and plexiglas daylight (Germany) | 2001 | English
In recent years several daylighting systems were developed. Due to a generally felt lack of daylight because of climatic conditions the development was mainly concentrated in Central Europe, Japan, the United States and Australia.
This paper describes the energy performance of an underground thermal energy storage system that consists of high efficiency heat pump and Borehole- Heat-Exchangers (BHE).
A study on the accuracy of daylighting simulation pf heavily obstructed buildings in Hong Kong | 2001 | English
Hong Kong is the most densely populated city in the world. The Building Regulations of Hong Kong pre- scribe a minimum distance between buildings for light- ing and ventilation.
Application of quasi-steady-state thermodynamic model of conventional heating system with Takahashi control method | 2001 | English
An indirect control technique using a single-zone space model is presented.
This paper presents the requirements of the building representation to supports the holistic performance assessment of building performance into a single application.
A simulation analysis of the opening of entrance doors and winter airflow into the entrance hall of a high-rise office building | 2001 | English
This study aims to develop a simplified estimation method of the thermal design load and space radiant environment in order to achieve adequate and economical HVAC equipment sizing and confirmation of thermal comfort.
Little work has been done on the closed loop response of refrigeration plant using the new chlorine-free refrigerants.
New calculation procedures for calculating conduction heat transfer for foundations are described. These procedures are first validated and then implemented within EnergyPlus source code (beta version 5.0).
A proposal for an estimation method of thermal load and space radiant environment for HVAC system design development by applying DOE technique | 2001 | English
This study aims to develop a simplified estimation method of the thermal design load and space radiant environment in order to achieve adequate and economical HVAC equipment sizing and confirmation of thermal comfort.
An object oriented multizone thermal building model based on the simulation environment smile | 2001 | English
A daylight simulation tool including transmitted direct and diffuse light: application to the evaluation of daylighting inside glazed intermediate spaces | 2001 | English
The paper describes new improvements in SOLENE, a set of numerical models for the simulation of natural light in both the urban morphologies and the indoor architectural spaces which is developed in our laboratory.
Classical building simulators are typically based on global systems of differential equations that model the physical reality and are numerically solved at runtime. In this paper we propose a new approach.
