Nearly 100 people met on Thursday 2 February at the XYLO construction site, the first tertiary wood building in the Grenoble region.The event of the day? The laying of the first timber - the equivalent of the first stone - of this flagship project for the region.
Designed to minimise carbon impact and optimise energy efficiency, XYLO illustrates the commitment of Linkcity and Bouygues Bâtiment Sud-Est to low-carbon development and construction, as well as to innovation for the ecological transition in conjunction with the region.
Built by Linkcity on behalf of the Société de Gestion Midi2i, this seven-storey building will provide users with 2,700 sq. m. of bright, modular office space that is conducive to the well-being of its users; 300 sq. m. of terraces, some of which are planted with trees and others are accessible; a 300 sq. m. ground-floor core area that will house a restaurant, enhanced by landscaped outdoor areas, including a large, multi-oriented outdoor terrace; and, finally, a large bicycle storage area, parking spaces and changing rooms and showers for sports enthusiasts.
A sober design, imagined by the architectural firm Composite Architects
From the first floor onwards, the entire structure is made of wood from European forests: floors, posts, beams and facades. Only the staircase core is made of concrete.
80,000 screws will be used to assemble the 4,000 m² of wood needed for the construction!
The production of heat and cold is also very virtuous: a geothermal heat pump is connected to the ZAC's drainage network (i.e. an energy production at least five times greater than that consumed to produce it).
The solar panels on the roof supply the building directly with energy for self-consumption, which further reduces the need for electricity.
XYLO reconciles the health and well-being of users, and has a very high environmental performance.
- BREEAM “Very Good” level (benchmark serving environmental quality and guaranteeing a high quality of life within the building)
- BBCA "efficient" level (label attesting to the exemplary carbon footprint of a building over its entire life cycle)
- the E3C2 level of the E+C- label (label encouraging the fight against climate change on the Energy (E) and Carbon (C) sections.
Work on the site began in September 2021 and involved up to 12 Bouygues Bâtiment Sud-Est workers at peak times. In early January, the teams began work on the production of the wooden structure from the first to the seventh floor, using CLT panels for the facades and floors, and glued laminated timber for the posts and beams.
Delivery is scheduled for the end of 2023.
