Above Lausanne, the 30-hectare Plaines-du-Loup eco-district has the ambition to welcome around 8,000 residents and create 3,000 jobs by 2034. The project intends to use cutting-edge technology while also meeting the city’s environmental, social and economic needs.
In keeping with the 2,000-watt society – the environmental vision set out by ETH Zurich for the average citizen to reduce their annual energy use to no more than 2,000 watts by 2050, without any loss in standard of living – the energy plan is ambitious. Heating and hot water are supplied via geothermal energy combined with heat pumps, alongside heat recovered from waste water. Photovoltaic solar panels will produce the additional electricity needed for the pumps and for the domestic hot water supply. This complex system was designed to provide a fully renewable, zero-carbon heating system.
