Q: Is the “Baseload” fuel use per year referencing domestic hot water only?  Is the “Heating” including the “Baseload”?

A: Baseload by definition is energy use not attributed to HVAC.


Q: What does the excel program turns utility bills into?

A: The utility data import tool converts your bills into a .csv file formatted for import into TREAT. It will also convert delivered fuels into an seasonal HVAC profile.


Q: Leaky basement doors can be replaced, to save leakage to outdoors from the basement… they can cost $500.  But the original door needs to be in TREAT to get this incentivized.

A: The door aspect of TREAT allows you to enter in customizable U values. To capture leakage savings please use the holes in the building inputs.


Q: Does that include basement as conditioned?

A: Basements can be modeled as unconditioned or conditioned.


Q: Can I use the equivalent leakage area as on my monometer?

A: No, enter infiltration as CFM50 or ACH.


Q: How do I model fans, like bath fans?

A: Fans in TREAT change air between the inside of the building and the outdoors, so use them to model equipment that does this.


Q: If I have 2′ above the ground and 5′ below the ground, how should this be treated?

A: This should be modeled as multiple surfaces.  One surface adjacent to ground, and one surface for each exposure of above grade wall.


Q: How to model two heating / cooling systems (1 for first floor, 1 for second floor).

A: Spaces and systems can be combined when they are similar enough in thermal condition and behavior, and if they do not need to be treated independently for improvements.


Q: For the utility import, my specific question is with regard to the XLS spreadsheet and conversion to CSV.  I continue to receive errors during this process.

A: Please submit a TREAT support ticket to share a specific occurrence of this problem.


Q: What is the volume of a coil in boiler…?

A: Depending on the size of the boiler, this could be a few gallons or many gallons. This should not have an enormous effect on the energy results.


Q: What is the efficiency of wood stoves?

A: This varies by wood stove. These can be modeled in a variety of ways depending on what other systems and improvements are desired. If ducted then a furnace will work, otherwise the “Other” system might be most appropriate


Q: Is there a data collection sheet for this that follows the software inputs?

A: Yes! Please visit the TREAT storeor contact TREAT Support ( to discuss the data input forms.


Q: On a two story colonial, can it modeled as a one story that is 16 feet tall?

A: We recommend this be modeled as an 8′ ceiling with the appropriate total conditioned floor area.
