Feasibility study, detailed design
The Tilia Tower is a pioneering work in the municipality of Prilly-Malley. Its surfaces will be the site of housing for different publics, hotels, modular coworking and comaking spaces, commercial areas, restaurants, sports facilities. The project envisages an ambitious and sustainable wooden building 85 metres high. Over its lifetime, the building will emit only 3.7 kg of CO2 per square metre. For this project, GEOEG performed the feasibility study and the detailed design of the energy foundation which included the thermal activation of the perimeter walls of the 3 underground floors and the foundation slab. Through these efforts, the energy performance and efficiency of the geothermal heat exchangers were quantified and optimized, resulting in a renewable energy system that greatly contributes to the Tilia Tower’s decarbonization efforts.
