Hello all, I am working on a project where a few of the AHUs and FCUs are defined but scheduled to be installed later in the future - phase II.

I’m currently working on a LEED certification of a public natatorium that has three swimming pool tanks.

How is ASHRAE 6.4.3.1.2 5 degree deadband interpreted? 70-75 deadband provides six temperatures in which the thermostat is "dead".

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?
