Abstract
This study is a part of a concrete sustainable development project introduced at university. A small scale genuine materials house (1/20 scale) with its green energy sources and electronic circuits management have been designed for educational and research purpose [1]. Thanks to a modular design and optional accessories, many thermal and electronic measurements and modelling are possible, like in a real house. A SPICE equivalent thermal behaviour modelling is proposed. Once validated, a case of study for a three floor small scale building is presented. Power consumption and insulation efficiency are analyzed. Main tendencies are checked after comparison with a real multi floor building. Results are finally discussed.
Highlights
This global project was carried out through national collaboration with “the House of the Nature and the Environment” (MNE) of Bordeaux, national french organism ADEME (Agency of the Environment and the Control of Energy) France, the ENSEIRBMATMECA (33400 Talence), the colleges Chambéry (33140 Villenave d' Ornon) and Henri Buisson (33400 Talence) for the realization of the small scale house
The aim of this study is not to make competition with existing well tried software but more surely to obtain a quite simple thermal behaviour modelling of a small scale building, in order to have an easy understanding compatible with our electronic culture
3.1 Equivalent SPICE Modelling For this purpose, previous “one floor small scale house modelling” with its temperature regulation circuit given in figure 6, is slightly adapted
Summary
This global project was carried out through national collaboration with “the House of the Nature and the Environment” (MNE) of Bordeaux, national french organism ADEME (Agency of the Environment and the Control of Energy) France, the ENSEIRBMATMECA (33400 Talence), the colleges Chambéry (33140 Villenave d' Ornon) and Henri Buisson (33400 Talence) (professors and pupils) for the realization of the small scale house. Pure thermal modelling is obviously a complex domain which requires high knowledge level and specialists [2], [3], [4]. The aim of this study is not to make competition with existing well tried software but more surely to obtain a quite simple thermal behaviour modelling of a small scale building, in order to have an easy understanding compatible with our electronic culture. Modelling must be just fine to understand main tendencies, the effect of double internal or external insulation, thermal inertia and to run simple day/night scenario in order to predict heating power consumption for educational purpose
