Russian City Is Cooling Ground to Preserve Buildings
Norilsk, a city of 170,000 in northern Russia, is mechanically cooling the ground in places to prevent the permafrost from melting. When the permafrost melts, the ground becomes soft and large buildings (like apartment blocks) will sink or tilt. So, about 8 million Euros are being spent to thermally stabilize the ground. This issue is […]
