LoginSeveral 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.

Volume content
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.
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
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.).
Brehomes a Physically Based Model of the Energy Use of the United Kingdon Housing Stock | 1991 | English
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.
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.
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.
The use and evaluation of a computer program for the investigation of the dayligth and sunlight performance of buldings | 1991 | English
This paper discusses the use of the computer program DAYLIGHT, as a method of analysing and evaluating the natural lighting in buildings.
Water vapor adsorption and transfer in microporous building materials: a network simulation | 1991 | English
In this paper, we develop a discrete approach to describe the transport of condensible vapors through a microporous substance.
The simplified thermaI simulation of buiIdings is particularly useful for both bioclimatic design and the selection of the most suitable HVAC systems.
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.
The Integration of a Radiator Network Dimensioning Program With A Building Product Model | 1991 | English
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.
Tools for Whole Model Validation of Building Simulation Programams Experience from the CEC Concerted Action PASSYS | 1991 | English
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.
The use of building emulators to evaluate the performance of building energy management systems | 1991 | English
Three complementary approaches may be used in the evaluation of the performance of building control systems-simulation, emulation and field testing.
Whole-Building Energy Targets: A Methodology for Future Performance-Based Standards | 1991 | English
Building energy simulation is playing an increasingly important role in the development and implementation of building energy codes and standards in the United States.
The simulation of large scale interconnected systems for building and equipment performence evaluation | 1991 | English
Presently, the building performance analysis requires to take accuratly into account the coupling effects between building, HVAC and control.
Using regression equations to determine the relative importance of inputs to energy simulation tools | 1991 | English
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.
The model coupling problem: methods used in some building analysis tools and the almeth propositions | 1991 | English
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.
With the accelerating use of building performance prediction models in a design context, the need for comprehensive program accreditation procedures is becoming more pressing.
Building design with a multi-discipline CAD system using object-oriented environment | 1991 | English
The aim of our paper is to present a multi-discipline CAD system named CONCEPTOR which allows the user to work during the various stages of the building engineering design.
