I have a residential facility seeking LEED v2009 certification with small room loads (approx 2,000 BTU/hr).

Hello Marcus, I have question regarding the energy simulation software.

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?

I have just begun working on a project that features a small (under 20,000sf) office building on a large public plaza on top of a below grade parking ramp.

when will the results of the ballot be posted?
