Tons are tCO2e. Single occupancy group only. Mixed-use buildings add each use's limit.

The four steps

  1. Multiply each energy source's annual use by its emissions factor and add them up. That is emitted tCO2e.
  2. Multiply floor area by the limit per square foot for the occupancy group. That is the limit.
  3. Subtract the limit from emitted tCO2e. If the result is negative, there is no penalty.
  4. Multiply the overage by $268.

Worked example
