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.
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.
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.
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.
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 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.
The traditional round hut has been analysed by simulating the sensitivity of its different components in order to establish their relative performance.
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.
General models for heat and mass transfer components have been developed for use in TRNSYS  thermal system simulations.
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.
Weather sequences for predicting HVAC system behavior in residential units located in climates tropical | 1997 | English
The purpose of our research deals with the description of a methodology for the definition of specific weather sequences and their influence on the energy needs of HVAC system. We’ll apply the method on the tropical Reunion Island.
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 simulated cooling plant equips an office building whose maximum cooling demand is about 5 MW.
The purpose of this paper is to present a new method to energy analysis. The method consist three different phases: in the first phase the target values of energy consumption are determined.
Optimisation of mechanical systems in an integrated building energy analysis program: part I, conventional central plant equipment | 1997 | English
This is the first of two papers that describe the development of simulation methods for optimally controlled central plant equipment which have been implemented in the IBLAST (Integrated Building Loads Analysis and System Thermodynamics) building
A series of linked spreadsheets has been developed for the analysis and modeling of thermal and daylighting effects on the flow of energy in buildings.
HOT2000™, a residential energy analysis program, is constantly under evolution. New models are added to the program and its user base is ever expanding.
