[Bldg-sim] Appendix G, Table G3.1.1A Building Type area is conditioned or unconditioned?

Ashraf,

 

As per ASHRAE 90.1 Appendix G, Table G.3.1.1A Building Type area is
conditioned. Refer Section G.3.1.1 Baseline HVAC System Type and
Description.

 

In your Case,

 

If conditioned area 15,000 ft² (150,000 ft² with only 10% of conditioned),
If Non residential and 3 floors or less and <25,000 ft² accordingly you can
select System 3 or 4.

 

If conditioned area 15,000 ft² (150,000 ft² with only 10% of conditioned),
If Non residential and 4 or 5 floors and <25,000 ft² or 5 floors or Less and
25,000ft² to 150,000 ft² accordingly you can select System 5 or 6.

 

Regards,

Bharathidhasan

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
