For Case 1, Type 2, where at least 20% of the system serves non-densely occupied zones, we have a situation where (1) dedicated outside air system (DOAS) serves several smaller heat pump (HP) zones

For projects served by evaporative cooler which is supplying 100% fresh air to conditioned spaces, is it still require to have an outdoor air delivery monitoring system. Even though at minimum flo

We are pursuing IEQc1 and we would like to use CO2 sensors connected to an Open Source Arduino micro controller in order to manage the alarms, interface with other systems and publish to Pachube (h

Does the (airflow sensor) need to have any specifications other than the required accuracy (which is 15%) which was mentioned in the study guide?

The project I am working on has large laundry area with outside air provided for makeup air for the dryer exhaust.

1. CO2 sensors are installed in our project, but not interconnected with fresh air fans. CO2 sensors will only monitor the CO2 levels and raise an alert when the levels are increased.

Do we have to install CO2 sensor in each retail unit if they will be considered as densely occupied areas according LEED definition?

Are CO2 sensors required in locker rooms? Loker rooms are non-regularly occupied spaces but they are also densely-occupied spaces.

I have a question relating to NC IEQ C 1.
