Tools to design and support your Ground Source Heat Pump installation
GLHEPro
GLHEPro Version 5.0 was released on the Spring of 2016 and has many new features, incorporating many years of research. This research has resulted in nearly 100 peer-reviewed papers and book chapters and has also led to many new features in GLHEPro. GLHEPro Version 5.0 has significantly expanded simulation and sizing options:
More information on GLHEPRO, including a downloadable version of the User’s Manual, is available at the GLHEPRO website.

New Features
Significant new features include:
- User-specified borehole configurations for up to 30 boreholes – these can be vertical or inclined and irregularly placed.
- Horizontal ground heat exchangers.
- Hourly simulations of GSHP systems.
- Worldwide database of time- and depth-varying ground temperatures.
- Hourly simulations of standing column wells.
- More detailed borehole model can account for short circuiting resistance and groundwater-filled boreholes.
- Improved flexibility in the hybrid system sizing feature.
Versions
GLHEPRO 5.0-30 can size user-specified configurations of up to 30 vertical or inclined boreholes. Custom g-functions are generated using a finite line source model. It can also size horizontal ground heat exchangers – both straight and slinky type heat exchangers. It can perform hourly simulations of GSHP systems with user-specified configurations of up to 30 boreholes or of GSHP systems with standing column wells.
GLHEPRO 5.0-120 does everything that GLHEPRO 5.0-30 can do, plus it contains a library of 407 pre-defined borehole configurations.
GLHEPRO 5. 0-400+does everything that GLHEPRO 5.0-120 can do, plus it can size large rectangular borefields with vertical boreholes, up to 990 boreholes.

“Geothermal Systems that Work by Design, Not By Accident”
Ground Loop Design software (GLDTM) is the world’s leading commercial GHX software design tool with design professionals in more than 60 countries using it in a dozen different languages to design English and Metric based systems. Colleges and Universities around the world use GLD as a teaching tool for designing geothermal vertical, horizontal, surface water, hybrid and coaxial systems properly and GLD is licensed by almost every branch of the US Military for their facilities.
- GLD’s flexible “Geothermal Design Studio” concept offers a user-friendly suite of modular tools that provide tremendous power and flexibility to the designer.
- This design tool easily handles multiple design comparisons and simultaneous projects.
- The new Piping System Builder simplifies and automatically creates an optimized piping interconnection system to tie the loopfield to the building.
- Coupled with the powerful CFD Module, you can now design headers the right way and do it with ease for systems that are both efficient and purgable using available real-world pump systems.
- The new large and unified fluids library provides a wealth of information for characterizing operation across the entire operating spectrum of the system. The Hybrid Controls offer unparalleled design power to see the real time impact of shedding part of your load to hybrid mechanical systems.
- With the GridBuilder for vertical designs, it is now possible to design your borehole layout with real-world configurations instead of just basic and limiting squares and rectangles.
- The Thermal Conductivity Module provides accurate characterization of borehole performance. With the robust reporting capabilities, you can choose a highly detailed or concise output from any of the design modules.
- The straightforward reports not only provide a system for neat and accurate internal record keeping but also can be used to create a professional presentation of information to clients.
- Beyond the practical concerns of system optimization, GLD offers designers of GSHP Systems a user friendly tool that handles simple or complex designs.

The BCD Plastic Pipe Design Calculator is a software tool that aids in designing plastic pressure pipe and tubing systems using the materials CPVC, HDPE, PEX, PE-RT, PP-R and PP-RCT. It is intended to assist designers using these materials for applications such as plumbing, water service, fire protection, hydronic piping (liquids), radiant heating & cooling, snow & ice melting, geothermal ground loops, district heating, and turf conditioning.
The tool includes five main functions:
- Pressure/Head Loss
- Pipe Weight/Volume
- Thermal Expansion/Contraction
- Hydraulic Shock
- Expansion Arm/Loop
The BCD Calculator utilizes dimensional data from ASTM International and CSA Group industry standards for these piping materials, as well as data gathered from various PPI research projects and publications.
