GeoExchange systems are becoming a highly sought-after system for both new and existing buildings of all types. This is largely due to a multitude of benefits; which include: their potential to lower building GHG emissions, they require relatively less space within the building than a conventional system, and they can operate year-round while providing heating and cooling as required. GeoExchange systems can be designed and implanted in many ways. This presentation will focus upon the three most common layouts, those being: closed-loop vertical, closed-loop horizontal, and open-loop vertical. Understanding what data is needed to be known when starting, how these layouts are designed and installed, the differences between them, as well as their respective benefits will allow for a better understanding of what application each GeoExchange layout could benefit. The applications touched upon during the presentation will include buildings where a GeoExchange system was reviewed for implementation or has been designed and installed. This will include a case study of one or two buildings where a GeoExchange system was designed and implemented and the issues that came with them during the design, construction, and building occupancy stages. These issues will briefly touch upon the integration of the GeoExchange system with the building mechanical systems, issues with site conditions, problems encountered during the installation process, dealing with regulatory bodies, and post-construction findings. How each issue was handled when they were encountered will also be discussed. In summary, the presentation will focus on the three typical GeoExchange system layouts, where these layouts could be used and where a layout could be better suited over another, and what issues can arise from using this type of system and how to go about handling them.
