Buoyancy driven flows have always been, and still are, difficult to model using CFD programs. Much validation work is required along with guidelines for the CFD practitioner about how to model such flows.
Malcolm J. Cook, Kevin J. Lomas
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.
Drury B. Crawley
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.
Graham H Galbraith, R Craig McLean, Jiansong Guo
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.
Sangho Choi & Moncef Krarti
A simulation program VENTOLA was developed to study behaviour of the microclimatic situation inside buildings housing domestic animals.
Pavel Kic, Roberto Chiumenti, Stefano Bortolussi, Francesco da Borso
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.
M. Schuler, H. Meyer, A. Knirsch, S. Holst, M. Hiller, W. A. Beckmann, N. Blair
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.
Ian Beausoleil-Morrison, Moncef Krarti
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.
Pekka Tuomaala, Kalevi Piira, Mika Vuolle
The  traditional  round  hut  has  been  analysed  by simulating the sensitivity of its different components in order to establish their relative performance.
Albert Malama and Steve Sharples
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.
Olaf Gutschker and Harald Rogaß
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.
Martin Jiranek & Zbynek Svoboda
General models for heat and mass transfer components have been developed for use in TRNSYS [1] thermal system simulations.
R. J. Rabehl, W. A. Beckman, J. W. Mitchell
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.
Vladimir Bazjanac, Drury B. Crawley
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.
L. Adelard, F. Garde, F. Pignolet-Tardan, H. Boyer, J.C. Gatina
We show here the actual state of a project based on n object-oriented philosophy, MotorLab.
Gilles Lefebvre, Elena Palomo, Maria del Mar Izquierdo
The simulated cooling plant equips an office building whose maximum cooling demand is about 5 MW.
Jean-Pascal Bourdouxhe, Philippe André
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.
Risto Kosonen & Jari Shemeikka
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
Russell D. Taylor and Curtis O. Pedersen
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.
David Lord
HOT2000™, a residential energy analysis program, is constantly under evolution. New models are added to the program and its user base is ever expanding.
