Hello Everyone,

I am simulating an office building using a DX system. There are rooms like storage rooms, electrical rooms with only exhaust fans, and stairs that have no cooling and heating. Since Appendix G requires me to model both heating and cooling identical to baseline (which is System 8). The proposed design will have a DX and chilled water system. Is that correct? Or should I just include these rooms with DX AC? Or should I just not simulate these rooms.

These rooms are less than 5% of the total area and Im not sure if I should add a chilled water system to add cooling and heating to these areas. Need some advice on these. Thanks.

Regards,

Jaigath Chandraprakash
