Revision history [back]

If you are delivering outside air with a gas-fired DOAS, then you have a gas baseline in the eyes of LEED.

If you have no gas heating, then you might be able to use the electric baseline:

• If you have no gas heating anywhere in the building, easy peasy, use the electric baseline. (system 6 instead of 5)
• If you have no gas in your VRF spaces, but you do have gas heating in other spaces, work very hard to see if those other spaces would qualify for a separate baseline system under G3.1.1 exceptions. Then you can make a case to have multiple baseline systems. If you do use multiple baseline systems, be sure to write a short narrative explaining which exception you are applying and why.

Good luck!

If you are delivering outside air to your VRF spaces with a gas-fired DOAS, then you have a gas baseline in the eyes of LEED. LEED, period.

If you have no gas heating, heating serving those spaces, then you might be able to use the electric baseline:

• If you have no gas heating anywhere anywhere in the building, easy peasy, use the electric baseline. (system 6 instead of 5)
• If you have no gas in your VRF spaces, but you do have gas heating in other spaces, work very hard to see if those other spaces would qualify for a separate baseline system under G3.1.1 exceptions. Then you can make a case to have multiple baseline systems. If you do use multiple baseline systems, be sure to write a short narrative explaining which exception you are applying and why.
