      District systems offer more cost-effective means of heating and cooling
      District systems, which have been around for centuries, provide buildings with a product created with technology beyond what an individual can either afford or apply. The primary advantage is the delivery of more cost-effective heating or cooling to the building.

Drinking Water Energy: The Time is Now PHC News Magazine
      This and other fluid exchange technologies provide real solutions that play a vital part in converting our building stock over to heat pumps.
      When we are talking about water energy, there is another type of hydropower that has to do with using water movement to transfer energy in the form of BTUs. It is one of the most basic and simple uses of water in every form. It has been safely done for generations and is the most efficient form of heating and cooling energy transfer.

Existing water infrastructure may hold key to generating more hydropower
      Millions of miles of pipelines and conduits across the United States make up an intricate network of waterways used for municipal, agricultural and industrial purposes.

      In a new report, researchers at the U.S. Department of Energy’s Oak Ridge National Laboratory have found potential opportunities in all 50 states to efficiently utilize existing infrastructure to harvest this otherwise wasted energy.

Breaking Down Barriers Official Magazine
      With the release of the 2021 UMC®, IAPMO became the first international code-development organization to provide regulatory guidelines in a mechanical code for installing geothermal energy systems used for HVAC and heating water.
      These provisions break down barriers hindering the growth of these technologies. Local codes lack direction, with planners wanting to know things like “If it’s not in the code, what do we do?” or “Whose jurisdiction is this?”
       By providing answers to questions like these, IAPMO is educating developers, assets
managers, designers, code officials and others about the benefits of geothermal energy and making it easier to consider them — which is less likely to happen if geothermal isn’t in the code.
