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!

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!

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.

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.
