The use of a simulation tool in order to obtain the thermal performance passive solar houses in Portugal | 1997 | English
This paper describes the methodology used in a simulation process that pretend to compare predicted and measured values.
By describing three recent case-studies, this paper aims to elaborate the current state of building energy modelling and simulation in the Czech Republic in general, and at the Czech Technical University (CTU) in Prague in particular.
Sun and climate modeling for thermal simulation: parametric models relevant at early design stages | 1997 | English
The traditionally engineering-oriented approach to thermal building simulations tends to leave such analysis tools out of the reach of general design practitioners, especially during the early stages of building design when many of the most influe
Stadium Australia is to be the centrepiece of the year 2000 Sydney Olympics. The architects aimed to minimise energy consumption by incorporating passive design measures which would provide ventilation, natural cooling and warming and daylight.
Optimisation of design criteria for solar space heating systems through modelling and simulation | 1997 | English
This paper is concerned with the optimisation of some design criteria for water based active solar space heating systems intended for residential applications in Cyprus.
Simulation of visual and thermal comfort related to daylighting and solar radiation in office buildings | 1997 | English
The research we develop consists in evaluating "radiative comfort" during no heating periods in dwelling space and particularly in office buildings. The expression "radiative comfort" is used to characterize the thermal and visual component of the
The simulations of the thermal performance of retrofitted existing residential buildings in Istambul with micro-DOE-2.1E | 1997 | English
In this study, the thermal performance of the external envelope of existing residential buildings in Istanbul and energy efficient retrofitting of these buildings are being investigated and modelled by MICRO DOE-2.1E.
Hollow core ventilated slab systems provide an effective means of utilizing the building structure as a thermal store.
SOMBRERO: shadow calculations on arbitrarily oriented surfaces as a preprocessor for simulation programs | 1997 | English
SOMBRERO, a PC-program running under the operating system WindowsTM, calculates the proportion of shaded area of an arbitrarily oriented surface surrounded by shading elements as a function of time and location.
Optimization and control of displacement ventilation systems in buildings require accurate modeling of aeraulic and thermal phenomena involved in the establishment or the destruction of thermal stratification in the room.
A simplified heat transfer calculation method for underground buildings is developed. The method is based on the results from the ITPE method and is suitable for seasonal heat loss calculation.
Central to the formulation of a mathematical model to describe moisture transport through porous building materials is the initial choice of the flow driving potentials.
Predicting foundation heat losses: neural networks versus the basesimp correlations | 1997 | English
This paper describes a series of tests that were performed to determine whether a neural-network model could outperform a correlation-based model in representing foundation heat losses.
A simulation program VENTOLA was developed to study behaviour of the microclimatic situation inside buildings housing domestic animals.
TRNSYS 14 goes windows and window 4.1/1/ : tool for energetic and visual building simulation | 1997 | English
New developments of both user-friendly interfaces and mathematical models have been added to the very known software package TRNSYS /2/, a transient system simulation program, during the last year.
The traditional round hut has been analysed by simulating the sensitivity of its different components in order to establish their relative performance.
A new generation building simulation tool combines the most important inter-acting physical processes (air infiltration and ventilation, heat transfer, and indoor air quality) in an reliable, effective, and flexible way.
General models for heat and mass transfer components have been developed for use in TRNSYS [1] thermal system simulations.
The conception of complex buildings with innovative facade elements often demands dynamic building simulations. In some cases the required thermal parameters of the components must be obtained by experimental investigations.
