Groenholland consultancy
Groenholland BV was incorporated in 1990 and started life as an environmental consultancy focused on soil and groundwater contamination studies and site remediation.
In 1996 the first groundsource activities were deployed quickly pointing the way to the use of vertical closed loops as the most reliable and trouble free way of using the ground as energy source and sink.
With a background in the Earth Sciences, Groenholland at first focused on the design and implementation of the vertical borehole heatexchangers (BHE). At the time little or no tools for designing these systems were available and a lot of time and resources have been used to develop relevant tools such as our in situ Geothermal Response Test (GRT), borehole and wellfield models and interactive models between the building installation and the BHE wellfield.
Starting 2003 Groenholland augmented its activities by expanding into the field of design and engineering of heatpump installations. This has resulted in a number of turnkey heatpump installations that provide heating and cooling to buildings.
The often multiple heatpump installations range from 30-50 kW to more then 600 kW of heating or cooling output. In most cases the heatpump installation is integrated into a larger coventional heating & cooling system, whereby the heatpump installation provides the sustainable and energy efficient bulk of the building requirement.
The installations are based on stand alone controls, that communicate with the building BMS and provide constant information on the efficiency and performance of the groundsource installation. Systems can accessed locally or via the internet.
