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?

We have a hotel development project in China seeking for the LEED-NC v2009 certification. We are now facing a problem of setting the baseline case for the energy model.

In the section 8.4 Feeder conductors shall be sized for a maximum voltage drop of 2% at design loadand branch circuit condutors shall be sized for a maximum voltage drop of 3% at design load. I'm
