While cities and local authorities are looking for cost-efficient, low-emission energy solutions, cold local heating networks are becoming increasingly important as a central component of sustainable urban planning.<\/p>\n\n\n\n<p>In the new residential neighbourhood in <strong>Gronau (Leine)<\/strong> this vision becomes reality. Supported by the technical expertise of <strong>M&amp;P Energy - Member of the SIERA Alliance<\/strong>, a network of European environmental and engineering experts, the project integrates a geothermal-based cold local heating network for the efficient and sustainable supply of a diverse building structure.<\/p>\n\n\n\n<p>The neighbourhood comprises <strong>82 detached houses, 86 semi-detached and terraced houses, 19 apartment blocks<\/strong> and a <strong>Day care centre<\/strong>.
