Guidance on the use of computational fluid dynamics for modelling buoyancy driven flows | 2001 | English
A directory of building energy software tools is now available on the web. The directory contains information on more than 100 tools ranging from research software to commercial products with thousands of users.
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.
The numerical model for verification of various radon protective measures has been developed. This model is based on the partial differencial equation for the two-dimensional steady-state radon transport caused by diffusion and convection.
Reproducing thermal coupling between components in a generic environment like Matlab | 1997 | English
We show here the actual state of a project based on n object-oriented philosophy, MotorLab.
The implementation of industry foundation classes in simulation tools for the building industry | 1997 | English
Industry Foundation Classes (IFC) provide an environment of interoperability among IFC-compliant software applications in the architecture, engineering, construction, and facilities management (AEC/FM) industry.
