Good afternoon,

I am modeling the baseline building hvac system for a Leed certification. There is a hvac system No.8 which serves two different zones on the same plane (a single system is required), providing primary air and cooling the environments. In the proposed building, an area has a fancoil while the other is directly connected to the AHU. Moving to the baseline, if both zones require cooling but only one requires air exchange, the second zone will receive an unnecessary air replacement, contradicting G3.1.2.5.

How can I fix the problem? Do I have to create more AHU?

Thank you @Eric.

I confirm that this was the standard 90.1-207. If I understood correctly, do you mean that in the baseline building I ha

I must perform a leed certification for a proposed building in which there is a hot water circuit connected to a solar collector. How do I have to model it in the baseline building? I have seen that in Table 7.8 there are some indications for electric water heaters but I find nothing about solar collectors.

Everything is clear. Thank you for the answer and the link to the other question, they were both useful.

The solar collectors serve the DHW circuit; there is an integrated electric resistance because the solar power is insuff
