Users import monthly or 8,760 hourly heating and cooling HVAC loads profiles from csv files or from a range of energy solution program formats. The user enters soil thermal properties typically from an in situ formation thermal conductivity test. The user then controls a range of flexible parameters and inputs to optimize the design (entering borefield configurations, land area available, borehole diameters, etc.). After completing a design, the user can optimize the "tie in", or piping configuration while considering purging/flushing, flow rates, head loss and Reynolds numbers for optimal heat transfer. After completing a design, users can export a BOM and/or conduct a lifecycle cost analysis.
Users can choose from nearly 30 types of customizable reports that range from borefield design reports to heat pump specification reports to life cycle costing reports.
GLD is a powerful suite of tools for comprehensive closed-loop geothermal system design, optimization, and simulation, as well as for geothermal life cycle costing. It is suited for use with vertical, horizontal, surface water, and hybrid geothermal systems. The user interface and streamlined controls make GLD very easy to use.
