ASHRAE’s “Geothermal Heating and Cooling: Design of Ground-Source Heat Pump Systems” book provides benchmarks, design strategies and information necessary for engineers and installers to avoid problems such as inefficient pumping, high-cost ground loop designs, inadequate outside air provisions and unnecessarily complex control schemes. It includes coverage of close-loop ground (ground-coupled), groundwater, surface water, GSHP equipment and GSHP piping.  A new section has results of recent field studies, as well as energy and demand characteristics.
