The control strategy of the thermal storage HVAC system gives a large effect to the storage efficiency which dominates the tank volume to a great extent. Authors introduce how the temperature distribution of the tank varies and gives a considerabl
This paper describes a recent extension to the ESPr system concerned with the simulation of facade and roof-integrated photovoltaic modules.
Numerical simulation of air flows: an essential tool of comfort optimization of modern buildings and HVAC systems | 1997 | English
The paper deals with the CFD (computational fluid dynamics) application to the comfort optimization of some complex architectural projects in which the physical interaction effects between the building and its environment affect strongly the build

The optimal insulation detail of the thermal bridge adjcent to hot water pipes in apartment buildings slabs | 1997 | English
The methods for evaluating the thermal performance of each insulation detail alternative with the multidimensional heat transfer simulation are presented to determine the optimal insulation details of the thermal bridges adjacent to hot water pipe
The need for a decrease in the energy consumption of buildings implies an adequate understanding of control strategies. This requires an intensive use of simulation tools for the design and test of controllers of HVAC equipment.
The effectiveness of simple shading devices in reducing the direct, diffuse and ground reflected components of solar radiation has been measured and compared to simulation predictions of the same. The simulation results were found to be very sensi
This paper explores a simulation-assisted building control strategy.
Modelling and simulation play a number of roles in engineering design studies. For Gaz de France, these studies must satisfy exacting criteria of quality and rapidity.
The implications of sky model selection for the prediction of daylight distribution in architectural spaces | 1997 | English
