The Working Space research project focuses on the development of a new modular wooden system for the vertical extension of existing administrative buildings. Thanks to a partnership between the Canton of Vaud and the Laboratory of Architecture and Sustainable Technologies (LAST), a first realization started on a building located in the center of Lausanne.

In a perspective of urban densification, the Working Space project allows to create new and comfortable spaces, enhancing existing urban resources and generating minimum environmental impacts.

The structure consists of large-scale elements, composed of a frame of interconnected posts and beams. This primary load-bearing system allows to rely on a limited number of points and to easily transmit the loads on the bearing parts of existing buildings. All elements are composed in strict consistency with this basic structural grid. The same applies for technical installations, in particular the heating system, the electrical network and the connections related to communication technologies.

The result is a particularly high level of prefabrication compared to current construction practices. In addition, the optimized dimensioning of each piece promotes an expression of lightness and simplicity of conveyance on the work site.

Working Space's design also aims at minimizing the consumption of non-renewable resources, both for construction and for operation. In order to reduce energy needs, it is based in particular on a bioclimatic approach.

The project also favors renewable energies, in particular by integrating an important surface of photovoltaic panels on the roof. Completely reaching the goals of the 2000 Watts society, the estimation highlights that the energy produced at the primary level is superior to that necessary for the construction, operation and mobility of the vertical extension users.

Thanks to its flexibility and the speed of its implementation, this new modular system meets various needs when transforming existing roofs and provides the capability to work on buildings already in operation.

After the research phase, it is particularly gratifying today to be able to experience the results of this research project in full scale. Welcoming this approach, a ceremony of the "laying of the first prefabricated part" was held on March 5th on the site, in the presence of Mr. Pascal Broulis, State Counsellor, Mr. Philippe Pont, head of SIPAL, Mr. Emmanuel Ventura, cantonal architect and Prof. Emmanuel Rey, head of the LAST.
