A Heating Network to Sustainably Supply Chastre’s Infrastructure.
Project Objectives
The Boischamp project in Chastre aims to develop a sustainable and accessible residential area, integrating a collective geothermal heating system from the design stage. The objective is to provide an efficient and decarbonized energy solution for 95 housing units, while addressing energy efficiency challenges, resident comfort, and long-term cost reduction.
Harnessing Geothermal Energy
Here, geothermal energy represents a concrete and sustainable alternative to traditional heating systems. By capturing the heat naturally present in the subsoil, this system allows for the supply of thermal energy to homes throughout the year, without combustion or local CO₂ emissions. This discreet, reliable, and renewable technology provides an appropriate response to the region’s carbon neutrality ambitions, while ensuring increased independence from fossil fuels and market price fluctuations. It transforms the subsoil into a sustainable resource for the benefit of residents.
