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.
Building thermal models reduction: improving exixting methods by taking spectral imputs characteristics into account | 1997 | English
Modal-based model reduction techniques have been modified in order to improve their performance when applied to building thermal models.
Since two years, the Dutch building consultancy practice has been supported by an integrated design environment to base its advices on.
Collaborative building engineering is a team effort in which many elements have to be combined into a unified structure. The aims of the architect, the engineer and all the other players have to merge into a seamless design process.
Evaluation of the finite control volume method in simulating thermal fire resistance of building elements | 1997 | English
Application of the finite control volume method on simulating thermal fire resistance of building materials and elements was evaluated. Example was taken on studying the thermal responses of a concrete column under fire.
This paper discusses a multi-year (MY) approach to building energy simulation and presents a pilot study in Hong Kong that investigates long-term building energy performance using MY weather data. Building energy simulations in the pilot study wer
This paper reports the first results of an ongoing project aimed at generating design information /knowledge for wet central heating (WCH) refurbishment in multi-family houses in Central Europe.
This paper describes the use of daylight coefficients in a computer tool which is based in Monte Carlo backward ray tracing merthod and was developed under the frame of DAYLIGHT- Europe EC Project.
Influence of modeling uncertainties on the simulation of building thermal comfort performance | 1997 | English
In this paper, the parameters in a building thermal simulation model are tracked, which are subject to modeling uncertainty, i.e. uncertainty arising from commonly applied physical assumptions and simplifications.
CA-SIS software has been developed on PC as a tool for engineering offices in their Heating, Ventilating and Air Conditioning studies.
Energy saving in office buildings: a case study in Rome through the use of DOE-2 and other simulation tools | 1997 | English
A large office building has been the object of a detailed feasibility study in order to select the most effective actions for energy saving in space cooling. Actions concerning the modification of building envelope layout, including materials, sha
Moisture permeability data presented as a mathematical function applicable to heat and moisture transport models | 1997 | English
The physics of moisture transfer is complex and as a result modelling is normally carried out on a macroscopic basis, with empirical coefficients used to simulate the transport process.
This paper briefly reviews recent research into the modelling of complex fenestration systems, before presenting some results obtained by the use of a new (developing) simulation model, utilising Monte Carlo Methods and Geometric Optics (ray traci
