In tropical humid climate, thermal environment can be controlled using natural ventilation. But this technic raises the problem of acoustic comfort. Some technical devices coping with aeraulic and acoustic comfort constraints exist but they are not suitable in all economic context. Thus the urban research is exploring built configurations performances for future urban planning. This article presents an exploratory simulation method of these physical parameters, and analyses results of two guadeloupean urban fabric tests.

People that work in office buildings have new needs in terms of comfort within their work place. We suggest to develop a multicriteria office cell façade, allowing to control luminous, thermal and airflow parameters. It will be controlled to offer global

The aim of the European SSHORT (Sustainable Social Housing Refurbishment Technologies) project is to increase and promote rational and efficient use of energy in the retrofitting of social housing buildings. In this scope, one step was to evaluate with simulation studies the technical and economical interest of selected sustainable technologies on standard collective social housings in participating countries.

Modelling of buildings with natural or hybrid ventilation systems requires the coupling of a thermal and an air flow model because of the strong mutual impact of the thermal and the air flow behaviour. The newly developed tool TRNFlow is the complete integration of the multizone air flow and pollutant transport model COMIS [Dorer 2001] into the thermal multizone building module of the building and system simulation program TRNSYS [Klein 2000]. An internal solver algorithm using

The software Sim_Zonal is a tool for evaluating indoor temperature and air flow distributions for residential and office buildings. The aim of this EDF (Electricity of France) software developed in collaboration with LEPTAB (University of La Rochelle) is to evaluate comfort problems and specifically risks of discomfort (risk of draught, indoor gradient temperature, etc..) with taking

This paper describes four simulation models, which reproduce energy and temperature measurements of occupied buildings very well. These buildings represent small to medium size residential low-energy buildings of different construction type, which are typical for mid-Europe. For the simulation, the software TRNSYS is used. The reproduction of measured energy and temperatures in time steps of 15 minutes is well suited for precise predictions on heating energy demand and comfort of the buildings and modifications of them.

The validation and development of turbulence models are still important issues related to Computational Fluid Dynamics for ventilation purposes. The present work continues the work initiated by (Voigt, 2002). Four turbulence models are reviewed, the k-e model, the k-w model and two blending models combining the k-e and the k-w model. The reason for testing the blending

There is a growing need for more complex control of ventilation systems to satisfy energy and environmental issues. SIMBAD Toolbox (SIMulator of Buildings And Devices), developed in the SIMULINK graphical environment is a library of HVAC components models that is used in the field of

The authors have developed a tool called SimSPARK able to automatically build dynamic zonal simulations of a building zone. In that study, SimSPARK architecture is described in details along with the current zonal model library. The applicability of this tool is also illustrated with the comparison of their zonal model in a ventilated room composed of 27 zones, with others models that don't include adsorption and desorption processes.

Generally the calculation methods ignore the interaction of air leakage and heat conduction in building envelope. The aim of this paper is to explore the different approaches that may be used to evaluate the energy impact of air infiltration through building walls and to compare those results with calculations done using the current method calculation.
