Heat Load Calculations

An integral process is establishing the buildings heating and cooling requirements. Heating systems must be properly sized for overall comfort and efficiency. Improper sizing of a heating system can lead to lower efficiency levels and higher heating costs, which goes against the reasons for installing a ground source heat pump system.

Reliable heat-load estimates are essential for selecting the right size and type of heat pump, distribution system and ground loop size. When done correctly, the heat-load estimate can save you hundreds of Euros in the cost of your heating equipment and will ensure the ground loop is also accurately designed for the buildings specific needs and requirements.

Heat load calculations are based on local climate conditions and the insulation levels in the building. Additional factors such as window orientation and shading, insulation, and air infiltration levels influence the heating requirements of each building. The more efficient the property, the smaller the heat requirement you will need and the lower your running costs.

GeoPro Design uses industry leading software to analyse each property and calculates the exact heating and cooling requirements.GeoPro Design uses the ASHRAE Transfer Function cooling load calculation procedures, ASHRAE design heating load calculation procedures, ASHRAE design weather data and ASHRAE design solar calculation procedures.

Our HVAC engineers calculate space and zone loads 24-hours a day for design days in each of the 12 months. In doing so they calculate heat flow for all room elements such as walls, windows, roofs, skylights, doors, lights, people, electrical equipment, non-electrical equipment, infiltration, floors and partitions considering time of day and time-of-year factors. This information is then used to accurately select the GSHP and design the ground loop.
