What if your underground parking was also a source of renewable energy for our buildings ? Enerdrape turns existing underground environments into renewable source of energy for the heating and cooling needs of buildings. We develop an architecturally integrated technology that allows to capture both geothermal and waste heat present in underground existing environments, such as underground parking, tunnels, stations and others. Our solution offers an alternative, cost-effective and easier way to source renewable heat for heat pumps systems. Enabling the energy transition and access to affordable and efficient renewable energy systems in existing urban environments.
