[Equest-users] Co2 Monitoring

[Sundharam, Premnath]

Hey Robert,

My understanding of the CO2 monitoring credit is that it ONLY requires
that you provide capabilities to monitor CO2 and not necessarily vary
the amount of outside air. So if your HVAC equipment cannot vary the
amount of OA you could still provide CO2 sensors that report the CO2
levels.

 

Everyone else: is this what your understanding as well?

 

Thanks

Prem

Gentlemen I have a question regarding 90.1 when modeling a space.  

 

The design we are using for a project is to provide minimum ventilation
(as called for in ASHRAE 62.1-2007) to all the spaces based on max
occupancy.  The spaces are offices and conference rooms, one or two
class rooms.  The heating and cooling load is provide in each space by
FCU.  The make-up air is preconditioned to 55 Degree F.  The relief air
passes through a heat recover unit to collect the heat from the relief
air. 

 

If was are not varying the make-up air quantity do we need to have CO2
monitoring in each space.

 

Do you believe we would get any push back from USGBC on this.

 

Has anyone dealt with this issue before.
