About the cover: A geothermal system is installed at a building
retrofit project in Toronto, Ontario, Canada, where GeoSource Energy
Inc. constructed a 113-borehole geothermal field. The system will
service a 1960s-vintage apartment as well as an adjacent new
condominium. The borefield design integrates both vertical and
angled-drilling techniques—a unique approach to borefield layout,
making this project possible. Photo courtesy Darryl Chow, GeoSource
