Thermal buildings simulation softwares need meteorological files in thermal comfort, energetic evaluation studies. Few tools can make significant meteorological data available such as generated typical year, representative days, or artificial meteorological database. This paper deals about the presentation of a new software, RUNEOLE, used to provide weather(More)
Electric load profiles of tropical islands in developed countries are characterised by morning, midday and evening peaks arising from all year round high power demand in the commercial and residential sectors, due mostly to air conditioning appliances and bad thermal conception of the building. The work presented in this paper has led to the conception of a(More)
The designers pre-occupation to reduce energy consumption and to achieve better thermal ambience levels, has favoured the setting up of numerous building thermal dynamic simulation programs. The progress in the modelling of phenomenas and its transfer into the professional field has resulted in various numerical approaches ranging from softwares dedicated(More)
The first purpose of our work has been to allow -as far as heat transfer modes, airflow calculation and meteorological data reconstitution are concernedthe integration of diverse interchangeable physical models in a single software tool for professional use, CODYRUN. The designer's objectives, precision requested and calculation time consideration, lead us(More)
Two main modelisation techniques are the analytic and systemic methods. After a presentation of each method applied to building simulation, this paper emphases the benefit of systemic modelisation for multizone cases. Using a conceptual description of a building issued of previous method, one particular sub-system appears naturally, i.e. the thermal zones.(More)
In this paper, Using the silicon CMOS technology, direct conversion mixer was fabricated on silicon substrate for a realization of the long distance wireless power transmission system. The size of the mixer is 0.8 mm × 0.5 mm. The input frequency of mixer is 24 GHz, and converted BB frequency is 30 MHz. The conversion loss and output power of mixer was -9(More)
The GEEB Team of the University of Reunion directed this research towards the optimization of the anaerobic digestion of solid and liquid waste by injection of leachate. The objectives are to assess the performances of this type of process (to accelerate the process of biological breakdown) and to require a better control of the physicochemical mechanisms(More)
The purpose of our research deals with the description of a methodology for the definition of specific weather sequences and their influence on the energy needs of HVAC system. We’ll apply the method on the tropical Reunion Island. The methodological approach based on a detailed analysis of weather sequences leads to a classification of climatic situations(More)
The studies presented here aim at defining and setting out a calculation code allowing the prediction of outdoor ambient thermal quality Designers of urban spaces are expecting more specialized information such as skilled rules which may be achieved by the presented code, at present in process of development. The physical system is identified as being(More)
This paper deals about the presentation of a new software RUNEOLE used to provide weather data in buildings physics. RUNEOLE associates three modules leading to the description, the modelling and the generation of weather data. The first module is dedicated to the description of each climatic variable included in the database. Graphic representation is(More)
