Workshop-Will Building information managing influence environmental quality of building assessment?
This conference was intended to address the digital model question in the framework of the environmental assessment tool. To answer, 3 digital tool experts of environmental simulation has been invited to bear witness
Title: Will Building Information Managing influence environmental quality of buildings assessment ?
Date: 3rd of July, 2014, Lyon, France
Location: Chamber of Commerce, Lyon, France
Target audience: SME
Number of participants: 26
- Topic 1 : Is it possible to make Life cycle calculation through the BIM? What ist actual situation and the existing links between Life cycle calculation tool and BIM tools?
- Topic 2 : What are the norms and perspectives?
- Topic 3 : BIM as a tool to integrate environmental approach in the building conception : dream or reality?
Galdric SIBIUDE, CSTB :
CSTB is working with the ELODIE software which is a collaborative software developed by them since 2008. It enables buildings life cycle analysis thanks to an objective and multi-criteria evaluation methodology about environmental impacts of a building. It takes into account components, energy and water consumptions, construction site, to define a result of building environmental performance. The environmental performance is evaluated with adapted building description modes. This enables declarations and communications about buildings environmental performances. Since a few months, a link has been established between ELODIE and the digital model. Project data are imported from the model, adapted to the ELODIE software, the calculation is made by Elodie and the results are retransferred in the model. Evolutions could extend to an evaluation of the global performance thanks to information’s posting like inside air quality, global cost or acoustic. Evolutions could also extend to an interoperability of multi-physic tools.
Rémy FAURE, TERAO :
TERAO is a structure that guarantees energy and environmental performance throughout the buildings life cycle. they work at several levels: from equipment of the building to urban layout. TERAO has several areas of expertise: sustainable layout, certification and exploitation, energy performance guarantee, international certification, sustainable development and HEQ. TERAO use principally model and environmental performance software which enables the realization of dynamic thermal simulations as: - CFD’s studies, - Consumption estimations, - Comfort studies, - Monitoring, - And also daylight intake simulations, life cycle analysis, thermal regulation calculations in the new and in the existing buildings TERAO distinguish several objectives connected to the BIM as time saving, industry involvement in transmission of homogenized and accurated information, and amelioration of quality studies and projects. But we have to be careful concerning the importation and exportation quality of models and the difficulty to make the existing model easier.
Karine LAPRAY, TRIBU / VAD :
TRIBU sees the digital model as a co-conception tool rather than a building evaluation. In this framework, the BIM could be a collaboration opportunity with a common language. In a first way, the BIM introduces itself as a calculating simplifier that didn’t take in account co-conception. Tools have to be simplified upstream and while not replacing Human. Moreover, TRIBU raised the question of tools compatibility and of complementarity of different tools that treat the same calculation, for summer comfort for example. Furthermore, the evolution and update questions don’t have to be neglected. To resume, digital model brings considerable time saving, but must be ludic and must make talks easier between the project manager and users. Moreover, the price is a primary vehicle for the dissemination of this tool. Indeed, for small companies, prices can quickly become unaffordable given size and means of these kinds of structures.
