Calculate required borehole depth
Calculating the required borehole depth is one of the most essential methods within the domain of borefield design. In this article, we will give you an overview of the different methods that are available in literature and we will discuss their advantages and disadvantages.
- Tutorial
Import coordinates from AutoCAD into GHEtool Cloud
Within GHEtool, you have the highest flexibility for borefield design. In this article, we show you how to export coordinates from a DWG file using AutoCAD and import them directly into GHEtool Cloud, allowing you to create the most accurate representation of your borefield in just a few minutes!

Hybrid systems (part 4) – optimise for balance
Designing hybrid systems is not trivial, as it requires finding the right balance between installed geothermal power, system imbalance, and overall performance. Within GHEtool, there were already two optimisation methods available for designing such systems: optimise for power and optimise for energy. Today, we’re introducing a third option to help you design even better hybrid systems!

Thermal behaviour of borefields (part 2): G-function
The thermal behaviour of borefields is rather complicated, spreading out over timescales ranging from hourly to yearly. This article describes the concept of g-functions to model the long-term (seasonal and yearly) behaviour of borefields.
- Physics
Thermal behaviour of borefields (part 1): Borehole thermal resistance
In order to design feasible and well-functioning geothermal borefields, it is important to understand the thermal behaviour of the system. In this article, we will look at the effective borehole thermal resistance as a means to model the short-term thermal behaviour of borefields.

Passive and active cooling for an office building
Combining passive and active cooling in your geothermal borefield allows you to take advantage of the best of both worlds. On the one hand, you can benefit from highly sustainable and efficient passive (or free) cooling, while on the other, you can reduce investment costs through an optimised active cooling design. This article demonstrates how you can use GHEtool to implement this intelligent combination!

Pressure drop and pump energy in GHEtool Cloud
For an efficient borefield design, you have to pay close attention to both the pressure drop and the pump energy consumption. In this article, we will explore the latest additions to GHEtool Cloud to help you with the hydraulic design of your borefield.
- Methods
Combined active cooling and passive cooling (part 1)
With borefields, you can have passive cooling, but sizing your borefield this way is rather expensive. Therefore, the option to use active cooling is sometimes proposed to reduce the investment cost. However, this increases electricity consumption compared to passive cooling. This article investigates whether and how it is possible to design a borefield for active cooling while maximising the use of passive cooling.

The importance of pressure drop in borefield design
Pressure drop is an important but often overlooked parameter in the hydraulic design of borefields. In this article, we explore what pressure drop is, what factors contribute to it, and why it is crucial to consider this parameter when designing a borefield.
- Physics, Tutorial
Ground properties for borefield design
Accurate borefield sizing relies heavily on having the correct ground properties. Since geothermal energy systems work by exchanging energy with the ground, obtaining precise ground data is essential for a well-designed system. In this article, we explore the key ground parameters needed for calculations in GHEtool Cloud.
- Tutorial, FAQ
Enter an EED project into GHEtool Cloud
How do you compare a calculation with Earth Energy Designer (EED) to a calculation with GHEtool Cloud? Both tools have different models and use slightly different import parameters. In this article, we will show you how to convert an EED project to a project in GHEtool Cloud and discuss the main differences you can expect between the two tools.
- Physics
Borefield quadrants
Insight is crucial for an accurate borefield design. Borefields are inherently complex due to numerous design parameters and uncertainties. In this article, we introduce the concept of borefield quadrants— a framework that can help you analyse your borefield design and better understand our upcoming articles on borefield physics.
- Tutorial
How to design with tilted boreholes?
When there is limited space to drill a borefield, it can be beneficial to design your borefields with certain tilted boreholes. GHEtool Cloud is one of the few borefield software solutions that allow you to design your borefields with tilted boreholes, and in this article, we go into detail about the definitions used when entering your borefield design into the tool.

Hybrid systems (part 3) – A case with GHEtool Cloud
Hybrid systems and especially hybrid geothermal systems are a proven and efficient way to sustainably heat and cool your buildings. By combining intelligent borefield design with other technologies (like an air-to-water heat pump or solar thermal collectors) you can get the best performance of your total HVAC system.

Hybrid systems (part 2) – design methodology
Hybrid systems offer a promising solution for tackling the increasing complexity of geothermal projects. This article explores different design methodologies to size a hybrid geothermal system for either maximum power or maximum energy.
