Several attempts have been made these past few years to obtain a simplified dynamic model of thermal behaviour of buildings from recorded data. System identification techniques are well known in other fields, such as aeronautics.

In conducting and teaching Building Simulation, we often find two main disadvantages of conventional models: inconsistency of simulation results obtained by different users of the same model, and long machine times required for annual simulations
L. Jankovic
Changing working processes not only in manufacturing and assembly but also in office work require advanced buildings which allow a maximum of flexibility towards building structure and all its services (HVAC, telecommunications etc.).
Christof A. Hertkorn
The CLIM 2000 software proposes a host architecture for dynamic, modular building energy modelling. CLIM 2000 provides a library of basic models, which in particular allows simulation of hydraulic heating networks.
Denis Covalet
Models used for forecasting of future energy demand are often econometrically based and do not attempt to look in detail at end uses of energy.
L. D. Shorrock, G. Henderson, J. H. F. Bown
Dimensioning programs for heating radiator networks are still today cumbersome to use. This project is trying to develope easy to use and fast calculation methods for the dimensioning and balancing of radiator networks.
Talonpoika Raine, Rissanen Hannu
This paper deals with the validation methodology used within the PASSYS project focusing on the developed method for empirical whole model validation of building energy simulation programs.
Soren Ostergaard Jensen, Rik Van de Perre
Three complementary approaches may be used in the evaluation of the performance of building control systems-simulation, emulation and field testing.
E. Hutter, P. Haves, S. Wang
Building energy simulation is playing an increasingly important role in the development and implementation of building energy codes and standards in the United States.
Robert S. Briggs, Michael R. Brambley
Presently, the building performance analysis requires to take accuratly into account the coupling effects between building, HVAC and control.
Louis Laret
A set of statistical regression equations was developed to predict relative heating and cooling loads of external zones of commercial buildings. The equations were derived from the coil loads predicted by several thousand DOE-2 simulations.
Patrick J. O'Neill, Drury B. Crawley, J. Steven Schliesing
The model coupling problem (MCP) is a general non trivial problem raised by the universal choice of modularity as a conceptual base for object programming and search for efficiency in software tools development.
R. Ebert, A.M. Dubois, J.L. Dufresne
With the accelerating use of building performance prediction models in a design context, the need for comprehensive program accreditation procedures is becoming more pressing.
J.A. Clarke, P. Strachan
CAD manufacturers are providing an increasing amount of integrated building design software. These integrated CAD systems have few, if any, facilities to assess building performance.
Don Mclean
A "detailed" model of a heat emitter in hot water circulation has been developed considering, two phases (liquid and metal), the non linear heat transfer and the enthalpy transport by the fluid.
L. Fulcheri, R. Attalage
This paper discusses the use of the computer program DAYLIGHT, as a method of analysing and evaluating the natural lighting in buildings.
Scheila Birch, Ian Frame
In this paper, we develop a discrete approach to describe the transport of condensible vapors through a microporous substance.
Daniel Quenard, Hérbet Salles
The simplified thermaI simulation of buiIdings is particularly useful for both bioclimatic design and the selection of the most suitable HVAC systems.
F. Groppl, C. Priolo
The topic of this paper is the use of low temperature air (40 F or 5 C) for room cooling. Cold air systems can offer energy and space savings relative to higher temperature cooling systems.
Allan Kirkpatrick, Tor Malmstrom, Kevin Knappmiller
This paper deals with an optimal control algorithm which enables to regulate the heating installation of a building with discontinuous occupation. The control structure is based on the quadratic optimization principle.
