Ground source heat pump design software, from the response test to the pipe network

Analysis Suite is a desktop application for the engineers who design ground source heat pump systems. TRT Analysis interprets the thermal response test, GHE Analysis sizes and simulates the borehole field, and GLN Analysis designs the network that connects it — one application, one download.

Analysis Suite 3.0

Three modules, one suite

A geothermal project is measured, then sized, then plumbed. Not every project needs all three — choose the modules yours calls for.

TRT Analysis

Version 3.0

The short-term g-function panel, with calibration sliders next to the residual histogram and the fitted curves over a measured record

Thermal response test analysis

The measurement that ties a design to the ground it will be drilled into. TRT Analysis fits the ground conductivity and the borehole resistance from a field record — including the records that were interrupted, which the straight-line methods cannot honestly use.

Infinite line source, and a neural network model trained on the short-term response
Interrupted and restarted tests interpreted without discarding the record
The fitted values carry into GHE Analysis, and you choose which technique's value travels

GHE Analysis

Version 3.0

The GSHP system panel: the schematic redraws itself for each system archetype — water-to-air, water-to-water zone, water-to-water central loop, and hybrid with auxiliary equipment

Ground loop sizing and simulation

The borehole field, drawn as it will be drilled and simulated hour by hour. Fluid temperatures over one to fifty years, groundwater flow inside the g-function rather than as a correction applied afterwards.

Fields to 625 boreholes and 500 m deep, in regular grids or fully irregular layouts
Hourly entering fluid temperature over one to fifty years, in a single pass
Sizing by the ASHRAE alternative method, and what drives the total length

GLN Analysis

Coming soonVersion 3.0

Ground loop network and header piping design

The part of the system that is not in the ground. GLN Analysis solves the network drawn as a piping and instrumentation diagram, and answers the four questions a ground loop is judged on — flow share, turbulence, pipe size, and the head the circulator must supply.

Newton-Raphson mass balance, Darcy-Weisbach losses, Swamee-Jain friction
Pump curves from manufacturer H-Q points, met against the resistance of their own circuit
Velocity and friction gradient checked against the recommended windows, pipe by pipe

Methods you can check, not claims you must accept

Every model in the three modules is published, peer-reviewed and cited on its own page. The software ships with executable verification scenarios that reproduce the published benchmarks on your own machine, and the hydraulic solver's own accuracy is checked against EPANET, a solver that owes us nothing.

Your projects stay yours

Nothing runs in the cloud. Projects are files on your own disk, and the simulation uses the cores of the machine you already have rather than a metered service. If your licence lapses, your files still open: the application reads them, recomputes them and draws every chart in consultation mode - you keep reading your own work, you simply cannot change it until you renew.

Read the manuals before you buy anything

Each module has a complete manual, and all three are open on this site - some seventy-five thousand words covering every input, every equation and every result, with the published sources named where they are used. Nothing is behind a form or a sales call. They are written by the engineers who designed, ran and interpreted these systems as consultants, at a spin-off of Polytechnique Montreal, and support answers come from the same people.

One licence, sized to the projects you actually run

Analysis Suite is licensed annually, in three tiers set by the size of the systems you design — a house, a commercial building, or a campus. Intermediate and Large include all three modules, at higher ceilings each step up; Small covers the borehole field and the network, without the thermal response test, for the projects that rarely need one. Every licence includes both Windows and macOS, the complete manuals, and every update released during your licence year.

Free for academic research and classroom use — the same ceilings as our largest tier. Write to us from your institutional address.

Questions we are asked

What does Analysis Suite do?

It designs a complete ground source heat pump system in one application: the thermal response test that measures the ground, the borehole field that exchanges heat with it, and the pipe network that connects the field to the plant room. Three modules, one installer, one licence, on Windows and macOS.

Can it simulate a ground source heat pump hour by hour?

Yes. It computes the entering fluid temperature at every hour of the design horizon, from one to fifty years, in a single pass — typically under ten seconds for a ten-year run. The simulation carries the building loads, the heat pump COP and capacity at the temperature they actually see, and the circulating pumps.

Can I try the software before buying?

Yes. The demo needs no account, no email address and no credit card: download it and it runs. It exposes every feature of the application with limited input ranges, so you can follow a complete workflow through all three modules before deciding anything. A licence lifts the limits immediately.

What does an annual licence include?

One year of full use from the date of purchase, on Windows and macOS, with every update released during that year and the complete manuals for all three modules. Your activation key arrives by email within minutes. Support answers come from the people who wrote the software.

Can I install it on more than one computer?

Each licence covers a single machine. If you need to move it to a new computer, write to us and we will transfer it. Network and floating licences are not available today.

Is it free for academic or teaching use?

Yes, for academic research and classroom use, at the same ceilings as our largest tier. Write to support@gheanalysis.com from your institutional address and tell us what you are working on. The software is developed at a spin-off of Polytechnique Montréal, and a share of its revenue already goes to the graduate students whose research it implements.

What happens to my project files when my licence ends?

They stay readable. Your projects are files on your own disk, not records in a service you rent, and the application still opens them without an active licence: it reads the project, recomputes it and draws every chart, in a consultation mode that simply does not let you change or save anything. Renewing restores full use.

Start with the demo

The demo runs the whole application - all three modules, every panel, a complete workflow - with limited input ranges and nothing to sign up for. The manuals are open on this site, so you can read exactly what the software does before you download it.
