Hi,

I am confused about Area mentioned in ASHRAE 90.1 Appendix G, Table G3.1.1A
Building Type area is conditioned or unconditioned?

ASHRAE clearly says in Table G3.1.3.7 that area is conditioned but above
table it doesn't specify.

If it is conditioned, suppose if I have building with area of 150,000 sqft
with only 10% of conditioned, then do I need to choose System 6? It's
difficulty to have savings.

Thanks in advance.

Regards,

Ashraf
