FAQs about IEQc6.2 :

I’m working on a project that has transient occupants. How does the IEQ space matrix address transients, and are transients required to have access to the controls?

Do I have to include all individual and multi-occupant spaces and do they have to be consistent across IEQc6.1 and IEQc6.2?

The categories given in the IEQ space matrix don’t really fit how some of the rooms in my project will be used. What should I do?

In some areas, individual fan coil units can be adjusted through the BMS, which can be accomplished by the occupant phoning the building manager. As each unit can be controlled, is this sufficient for occupant controllability? A benefit is that the BMS ca

Multiple HVAC Zone Controls - Credit towards Individual Comfort?

In a current commerical office project, we are considering the following thermal controls: -Individual thermostats for each private office or meeting room -One open office space with +/- 10 workstations, serviced by one operable window and one thermostat with adjustable settings for 3 separate HVAC zones (one for each AC unit serving the space). The individual thermostats clearly contribute to the credit, but in the open office area where multiple settings are available - does this meet the credit intent for a partial percentage of the occupants? Could it be considered that 3 occupants within this space out of the 10 have "individual controls"?

Hi Jason, Yes, you are all set for the private offices with the individual thermostats. In terms of the open office area, is it the case where you have 3 occupants that you could argue in each different zone? Are the zones distributed in such a way that one occupant from each zone could realistically go to the thermostat and just change the temperature of their zone and not the others? If so, I think you can make an argument for achievement through your narrative. I would provide a clear floor plan showing where occupants are in the open floor plan area and how 3 people, in 3 different zones, could control their temperature. Good luck!
