Greetings, We have zones in our project which are addressed to system 9 (heating only).

I have a small facility (20k sqft or so) that is approximately 45% office and 55% "transitional" residential. I've modeled it as a residential with PTAC w/ HW Coil per zone, but I'm running into a

I am working on a project where natural gas generator is used power generation and the waste heat is recovered to run the VAM chiller.

Hello, My name is Ricardo from Mexico City.

According to system 3 of Table G3.1.1A I have to model a fossil fuel furnace for a baseline model. What efficiency shall I consider? "Warm air unit heater, gas-fired" in Table 6.8.1E, i.e. 80%?

When the baseline system is required to have DCV, how should it be controlled. I'm not aware of any sections that details how the controls should work when it is implemented for the baseline.

Hi, We are designing a building for tropical climate condition and thinking of having natural ventilation and mechanical ventilation only. i.e.

What is the baseline for a ventilation fan providing outdoor air to an unconditioned space?
