EQc6.2 and EAc1.3 for Zoning and Controls

It's possible, but not common: EQc 6.2 is difficult to achieve. Usually this would require an underfloor air system (UFAD) with one controllable vent for every two work stations. It may also be possible in a small office where the majority of work spaces are along the perimeter and close to operable windows.

It's definitely possible to get both credits as I've done it many times. However, EQc6.2 is tricky as David notes. Remember that EQc6.2 can be achieved with a combination of thermostats (manual controls) as well as operable windows. EQc6.2 can be particularly tricky when you have an open office space area but if you have individual offices with controls it's a little easier. EQc6.2 can also be achieved by controlling any of the thermal comfort criteria (air temperature, radiant temperature, humidity and air speed).

Dear All,

I am undertaking a project in france and we will reuse the existing system, which will provide heating and cooling from the ceiling and not an underfloor air system (UFAD). For the conference/meeting room and private office we can provide individual adjustable thermostat. But for the Open space office, the system will be link to a BMS. If we are including local control to ensure that 50% of the tenants occupants have an individual controls, will i meet the requirements to achieve this credit.

Thanks

Hi Cyril,

What kinds of individual controls are you able to provide in the open office area? If it is the case that 50% of your workstations in your open office area have controls, then it appears you are generally meeting the requirements of the credit.

Remember that for conference rooms and meeting rooms, reviewers will want to see that you have controllability to satisfy the needs of the space. In other words, if you have one area that could be partitioned off from the other, then it might warrant two control settings for these two kinds of spaces. Also, private offices sometimes contain more than one occupant. The reviewer will want to see how many controls you have per person, and not per room when it comes to private offices. So, if you have two people in one private office and one thermostat, then only 50% of those occupants have controllability.

Hope that helps a bit.
