Laying of the foundation stone for the Osiris eco-quarter in Echallens
Today Steiner invited the representatives of the client of the Osiris project, the Echallens community and the specialist planners to the ceremonial laying of the foundation stone. The ceremony symbolically marks the beginning of the construction of a new structure. In his most important construction project for an eco-quarter in western Switzerland, Steiner attaches particular importance to the ecological aspects of the building.
The eco quarter was developed as a joint project by Realtim, Equitim and ODS Investhome. The aim is to achieve Minergie-P-Eco certification, which includes the integration of environmental aspects in the construction process. That is why Steiner is using more than 50 percent recycled concrete in this project. In addition, strict criteria for reducing gray energy and labeling materials such as wood must be adhered to. The Steiner teams also pay close attention to effective waste and wastewater treatment on site.
The general contractor is aware of the importance of short transport routes and works with local subcontractors as far as possible on all projects. Currently, 75% of those involved in the project come from a radius of less than 50 kilometers around the Osiris construction site.
At the same time close to nature and in the city center
The planned eco-quarter comprises 15 buildings with a total of 410 apartments. It offers a natural, spacious outdoor area and foot and bike paths. Both the heating (heat pumps with geothermal probes) and the electricity (photovoltaic modules) rely on renewable energies. Another ecological advantage: the reversible heating system is used for surface cooling in summer (free cooling). Located not far from the center of Echallens, the eco-district has the ideal conditions for non-motorized traffic; the site will be equipped with paths and bicycle garages accessible for bicycles.
After the client had completed the earthworks, Steiner began building the shell in the summer of 2021. As the project was divided into several areas, the different areas are in different construction phases. The buildings in the first area are at an advanced stage, while the basement and first above-ground floors of the other two areas are currently only being built. The building handover of the Osiris project will take place in spring 2023.
