An Approach to Thermal Modelling and Simulation of Buildings at Gaz de France

The approach adopted by the Gaz de France Research Center for the modelling-simulation of building performance separates as far as possible modelling from simulation. Emphasis is placed on modelling and its validation. In the proposed approach, a model library in the form of PROFORMA forms is set up. Its aim is to provide researchers with a set of models characterized, in particular, by their state of validation. The engineer selects the models and the simulation tool he needs in order to obtain the numerical results corresponding to the objectives of his study. The simulation can be made using a range of software, including CSTBt/TRNSYS and ALLAN SIMULATION/ NEPTUNIX. The different model validation techniques, experimental validation in particular, enable us to make headway in our understanding and in the design of new products. This approach aims to make optimum use of the models and softwares. The initial work carried out in the context is presented.
