System Loads
System Loads or Peak Loads are calculated based on a variety of details for an individual residence. Assumed occupancy levels, the number of appliances operating, the number of doors & windows and the tightness of the construction all contribute to the amount of energy required to maintain the thermostat set points given the historical extreme weather conditions in your area.
The peak loads used in this report were provided as listed in the following table.

The peak loads for each individual zone are used to calculate the total amount of
heating & cooling capacity required for a space based on the set points and the climate
data for your area.
The installed capacity check describes the efficiency and total heating/cooling capacity
of the selected ground source heat pump system. This information is used to ensure
proper sizing of equipment based on the load represented by this zone.
The ground source heat pump below has been selected to maintain comfortable heat-
ing & cooling for this zone.

Earth Temperature Data Location
Formation Details
Deep earth (below 20ft) temperature is a function of the average annual air tempera-
ture in your region and remains relatively constant regardless of season.
The thermal properties of your formation are based on the formation’s composition and
have a direct impact on the scale of your loopfield.
Grout is used inside of all bores in order to protect the deep earth environment from
surface contaminants and to provide a more effective contact surface with GHEX piping
that optimizes heat transfer between the fluid pumped through your GSHP and the earth.
