Monitoring of efficiency energy savings

Essential information and feedback often overlooked.

Groundsource heatpump installations are intended to provide climate comfort and save energy. Monitoring of the installation will provide this information and will allow the client to evaluate the energy performance and if required make adjustment to the operating strategy.

Many buildings anticipate future energy usage based on average climatic conditions and on expected internal building loads. Was the groundsource installation efficiently designed and is it still efficient, even though changes in the building regime might have occurred? These and other questions relating to plant efficiency and changing operating strategies can be answered through a monitoring programme measuring the actual plant performance and operating characteristics.

Groenholland groundsource heat pump installations offer base-line monitoring as a standard option. If high accuracy monitoring and energy metering is required, this is available as an option.




Energy savings

The calculation and outcome of energy saving is always in comparison to some other type of heating/cooling solution. Usually conventional plant, using a gas-fired boiler and electrical chillers are used to compare energy savings and emission reductions.

The efficiency of the conventional plant and ground source heat pump plant is based on realistic assumptions. The total amount of primary energy consumed to generate a certain amount of heating and cooling to the building can be calculated. With this primary energy consumption and appropriate CO2 factors the greenhouse gas emissions can be calculated.

Savings of between 30% - 50% are to be expected for a well designed GSHP project.
