Gaps between intended and actual performance which impact on indoor environment, energy use and carbon emissions have been well documented and are nowhere more important than when they present in performance problems such as building overheating and consequent occupant discomfort and high energy running costs. Here such gaps are explored through a review of relevant literature and related illus...

This paper describes the conclusions of a reflection driven by a virtual team, composed of three research teams (one in computing at LORIA, one in telecommunications at France Telecom R&D, and a last one in building construction and design at CRAI) in the context of a common project. The topic of this project is the coordination of a virtual team in the context of a virtual enterprise, with exp...

1. Background The building industry agrees upon the fact that the construction process is fragmentary, this being probably the main reason for problems with the profitability and the quality of the products. The adoption of Information Technology (IT) has changed the building industry in more than one way. The need of information sharing during the different stages: building design, constructio...

it has been shown that geopolymerization can transform a wide range of waste aluminosilicate materials into building materials with excellent chemical and physical properties such as fire and acid resistance. in this research work, geopolymerization of construction waste materials with different alkali-activators based on combinations of na2sio3 and naoh has been investigated. a number of syste...

This paper poses the problem of fabricating physical construction sets from example geometry: A construction set provides a small number of different types of building blocks from which the example model as well as many similar variants can be reassembled. This process is formalized by tiling grammars. Our core contribution is an approach for simplifying tiling grammars such that we obtain phys...

The construction industry has acknowledged that its current working practices are in need of substantial improvements in quality and efficiency and has identified that computer modeling techniques and the use of prefabricated components can help reduce times, costs, and minimise defects and problems of on-site construction. This paper describes a virtual environment to support the construction ...

With the growth of information technologies in the field of construction industry over the last years, numerical building information modeling and process simulation has evolved to a fully accepted and widely used tool for project life circle management. A growing diversity between disciplines, participants, tasks, tools and events while project management in design and construction stages, the...
