A project space contains mixed mode ventilation where tenants share a central HVAC system. A tenant spaces has an occupant density of 30 people per 1000 sq. ft. What needs to be added to the project design to achieve Indoor Environmental Quality Credit, Outdoor Air Delivery Monitoring? (choose 2)

A: Install monitoring equipment that generates an alarm when conditions vary by 15% or more of the outdoor air intake flow
B: Occupant controls must be installed in all shared-multioccupant spaces
C: A minimum of 10 cfm per person of air must be delivered
D: The natural ventilation areas must meet the recommendations of the Carbon Trust’s Good Practice Guide 237
E: Install CO2 monitoring at locations between 36 and 72 inches above the floor

参考答案: AE

本题解释:
See Indoor Environmental Quality Credit, Outdoor Air Delivery Monitoring, Requirements
Monitors need to be installed between 36 and 72 inches above the floor (within the vertical breathing zone) in densely occupied spaces.

For mechanically ventilated spaces CO2 monitoring equipment must generate an alarm when the minimum outdoor air intake varies by 15% or more from the design case.

10 cfm of air / person is needed for Indoor Environmental Quality Prerequisite, Minimum Indoor Air Quality Performance.

Occupant controls are used for Indoor Environmental Quality Credit, Controllability of Systems-Thermal Comfort.

Natural ventilation must meet the Carbon Trust Good Practice Guide 237 for Indoor Environmental Quality Credit, Increased Ventilation.
