LESOSAI-POLYSUN - simulation tool for architects

Rapport final (Anglais)

Solar energy, in its various forms of passive solar, active thermal and photovoltaics, will be more and more used by architects in their buildings. Computer tools to simulate the thermal behaviour of buildings and solar systems are mostly used by engineers and thermal energy experts, while only some architects use these tools. The goals of this project were twofold: - combine in one tool the building energy model and all passive and active “solar” gains (windows, thermal collector, photovoltaics), allowing the user to optimise his project by testing complete solar variants at once. - simplify the user interface, by reducing the need of data by providing “intelligent” default values for solar systems and building elements, to broaden the use of this tool to the architects community Each of the 3 project partners reached their projected goals with very satisfactory results: Vela Solaris have produced a “Polysun inside” module that has been designed and used for this project within LESOSAI-P. The design of this module has allowed it to be also used with other computer simulation programs. E4Tech has successfully launched the 7th. release of LESOSAI, which includes both the “Polysun inside” module and the newly developed “wizard” to ease and simplify the work of entering a building in LESOSAI, mainly addressed to architects. The LESO-PB has coordinated the whole project and developed the ergonomic concept and the graphical interface of the new “wizard” for LESOSAI described above. The new concept includes recommendations collected from a user’s survey designed and conducted with the help of E4Tech, within this project.
