Hi,
This is a question specifically for the ResStock team at NREL.
When trying to estimate the capital cost of units installed, there can be a normalized cost ($/(kbtu/hr)) and a fixed cost. Specifically I am trying to calculate the normalized cost based off of the ResStock output for 3 different equipment; ASHP, MSHP, and GSHP.
I am simulating in a really cold climate (Maine) so I want to be sure I am not underestimating the size of the equipment needed.
ASHP has two capacity fields;
These units are in watts. There is also a simulation_output_report.size_heating_system_kbtu_h field, which for ASHP is equal in value to the hvac_heating_capacity_w field after performing unit conversions.
Which of these three fields (after appropriately converting units) should I use for estimating the normalized cost? Should I sum hvac_heating_capacity_w and hvac_heating_supp_capacity_w?
Would the method change for MSHP, ASHP, or GSHP? I noticed that MSHP has hvac_heating_supp_capacity_w = hvac_heating_capacity_w, while GSHP has a value for hvac_heating_supp_capacity_w that is larger than hvac_heating_capacity_w.
