C0 sensors in Carparks and demand control ventilation

NC-2009 EAc1: Optimize Energy Performance
posted by V. Miller on Dec 16, 2010, 8:09 am

Hi everyone,

I am looking to account for C0 sensors in a basement carpak as part NC building model for LEED. My understanding is that for carparks the baseline model has contionuous...

Modeling Proposed Airflow?

NC-2009 EAc1: Optimize Energy Performance
posted by Barbara McCrary on Oct 18, 2010, 4:23 pm

I started a previous thread on DX systems. Let me step back and see if anyone can help me with my larger question - Do we have to model the design airflow rate of our proposed system? A comment...
