RE: [EnergyPlus_Support] Question on Multiple zones per floors

ASHRAE 90.1 appendix G

This is a guide line, when you do not know what to do.

When you have an actual case, the guilde line need not apply.

If you have many details in your actual plan and is not shown, then appling the guide line would result in less zones to simulate. The question is then will LEED certificates prepared in this way be acceptable.

I am not interested in generating LEED certificate.

Because LEED is interested in typical and averaged annual energy charges which is maialy occupancy and weather dependent. Therefore, they have their guide lines. If cost of gas per heat unit is less, a gas boiler should be used. Eplus will give you that, but it does not reduce the energy consumption.

That is why I said, high rise is by default not energy efficient.

One storey residential building does not need cooling in Summer, excep for special cases.

Hood for oven, duct vent for dryer, attic ventilation, etc.

I still do not know what is meant by "a base line model". The multiple five zone model?

Subject: [EnergyPlus_Support] Question on Multiple zones per floors

I have attached my question and image for better discussion on multiple zone per floor. I really appreciate all thought.

I am doing a research on building typologies to compare energy demand, embodies carbon, water, etc. from Super-tall building, high-rise, mid-rise, low-rise, to single home family in the same amount of units. I am using OpenStudio for interface and run EnergyPlus for energy simulation. I would like to set the best base line medelling strategy which will effect to all building typologies energy performance.

ASHRAE 90.1 appendix G. has described on perimeter spaces should locate within 5 meter (15 feet). but in real building the lease space can be more than 5 meter.

There are corridor and service core which both are different conditions and schedules. How could we possibly model just 5 zone per floor?
