‘People Are So Proud of This’: How River and Lake Water Is Cooling Buildings

The article discusses the use of water bodies to cool buildings, a practice known as water-based district cooling. This method involves transferring excess heat from buildings into nearby rivers, lakes, or other water sources through a network of pipes and heat exchangers. However, as the world warms, the cooling potential of some water courses is diminishing, posing challenges for this sustainable cooling approach. The article highlights how water-based district cooling is a cost-effective and energy-efficient alternative to traditional air conditioning systems, with the potential to significantly reduce carbon emissions. However, as the effects of climate change become more pronounced, the availability and temperature of water bodies used for cooling may not be sufficient, requiring adaptations to maintain the effectiveness of this cooling method. The article emphasizes the importance of understanding the impact of climate change on water resources and exploring ways to optimize water-based district cooling systems to ensure their continued viability as a sustainable cooling solution.
