A building with a well designed GCHP system uses about 60% to 70% less energy for heating, cooling and domestic hot water than the same building built with a conventional fossil fuel heating system and a conventional air cooled chiller. If the system integrates other renewable technologies and thermal energy storage, energy use can be reduced even more. With concerns about climate change (whether it's real or not), more building owners and developers are making changes to the way their buildings are designed.
In my blog I'll be expressing my opinions about what I've the learned about ground coupled heat pump (GCHP) systems over the last 30 years. I've been very fortunate to work with many interesting people who are passionate about this technology...engineers, geologists, mechanical contractors, drillers, excavation contractors...in different parts of the world. I've learned a lot from them and will be using this forum to pass on some of the things I've learned and feel are important. Please feel free to use this information if you feel it's worthwhile...hopefully you can avoid some of the same mistakes I've learned from.
