Hi there, I am modelling a 3,000 sqft house which is designed as using two gas powered furnaces to heat the entire house. They are the same model of furnace, one has a capacity of 80,000 BTUh and the…Continue

"We do not find many 3,000 square foot homes that require 140,000 BTU's of heat but that is another subject. Could you use one 120,000 BTU fully modulating gas warm air furnace?"

"This screams oversized! Why the two furnaces? Split system for two floors? I would think 2 furnaces would use more energy than 1. As you have to start up and power two blowers now. Sorry not familiar with HOT2000. Good Luck! "

HOT2000 - supplementary heating not being taken into account

Hi there, I am modelling a 3,000 sqft house which is designed as using two gas powered furnaces to heat the entire house. They are the same model of furnace, one has a capacity of 80,000 BTUh and the other of 60,000 BTUh. I am modelling the 80,000 BTUh furnace in the Type 1 furnace tab of the heating/cooling section, and the other furnace as a supplementary heating source. My problem is that HOT2000 does not seem to be taking the supplementary heating source into account. I have an error…See More

HOT2000 - model first floor garage?

Hi all, I am modelling a proposed new residence in HOT2000 to prove code compliance to our local jurisdiction. The building is three storeys with a slab-on-grade foundation, and the first storey is a garage. The living spaces are on the second and third floors. My question is, how should I model this in HOT2000? The garage is heated and the garage walls are insulated, and the floor between the first and second storeys (above the garage) is insulated, obviously. Does anyone know if I can model…See More

"I agree. 99% of the time additions are best suited for the prescriptive method. No modeling needed."

HOT2000 Modelling Addition

Hi all, I am a new energy modeler in Canada, and I am trying to figure out how to model an addition to an existing house. The addition will use the existing furnace. I was thinking I would only model the addition, but in the "Natural Air Infiltration" tab, I would enter in the volume for the entire house, and make sure that the output capacities for the existing HRV reflect the addition. Any thoughts? Has anyone modeled an addition in HOT2000 before? Thanks!See More

Hi Kyla,

Yes, Dave is right.. you need to model the whole house. Model the existing wall perimeters, up until where the hypothetical addition walls start, and then model those separately. You would ignore any old walls that would essentially become inside space after the addition is completed (except for any shared foundation walls). Note that depending on the size of the addition, the output capacity of the heating system might need to be increased so you don't get an error message.
