Harnessing Heat From Underground Car Parks

Scientists in Germany and Switzerland measured the ambient air temperature of underground car parks, and the temperature of the groundwater beneath them, and found that those car parks generate a lot of waste heat, which heats the groundwater and impacts on biodiversity and water quality. Extrapolating their findings, the scientists estimate that all 5040 underground car parks in Berlin could heat 14,660 average German homes by harnessing the waste heat using heat pumps.
