The first One Planet Living (OPL) neighbourhood in Switzerland!

Published on 03.10.2017

The project to build the new Gruvatiez neighbourhood in the Orbe plain was presented to the population on September 2.

With an area of 56,000 m2, this development will accommodate 1,200 residents and create some 200 jobs in the long term. It will also be the first complex certified “One Planet Living” (OPL) in Switzerland. This WWF certification developed in 2004 concerns energy efficiency, the use of local ecological materials, water management and the enrichment of the surrounding biodiversity, and is based on ten strict and controlled sustainability principles during the entire production process and the operating phase.

In late June, the city of Orbe, WWF and the developer Orllati signed the convention and the objectives of the future neighbourhood. The complex is now undergoing a public inquiry with regard to the first stage of realisation. Construction is expected to start in the spring of 2018. As regards the sustainability principles, the carbon footprint must be reduced to one third of the Swiss average. No vehicles must be used within the perimeter, converted into biotopes and urban gardens, 20% of the food in the neighbourhood must be local and 55% of Swiss origin. As regards mobility, an RER stop will be operational in 2020, providing a direct connection with central Orbe, Yverdon-les-Bains and Lausanne. This is a challenge both for the residents who will live there and for the developer. Orllati must control its subcontractors, ban pollutants, limit travel and waste, avoid certain insulating materials and manufacture its concrete on site!

The area will be equipped with numerous solar panels as well as a rainwater recovery system, and will include shared vegetable gardens and orchards as well as local shops. The development will also feature children's play areas, a multipurpose hall for the local residents’ association and a childcare centre.

BG is particularly proud to be able to support this innovative project in all its facets: technical studies and OPL support, energy strategy and contracting, integrated neighbourhood engineering, on behalf of three clients: the city of Orbe, Orllati Real Estate and VO Energies.

BG became involved in the project in the early stages to develop the energy concept of the Partial Allocation Plan. Among the several energy concepts proposed by BG in line with the Energy Law, the concept of a geothermal doublet on Orb's aquifer was selected.

BG also designed the entire hot and cold water production and supply system in the district and provides specialised engineering services for the HVAC and MCR systems, namely all technical services according to SIA 108.

The civil engineering services according to SIA 103 are also provided by BG, which defined a simple, sustainable structural concept in order to meet OPL performance requirements for grey energy, in other words the requirements for ECO measurements as well as excavations and retaining structures.

In parallel, BG supports the project partners in developing a global energy contracting model (heating and electricity), meeting the OPL performance requirements.
