Q29. Are owners of commercial buildings required to report?

A29. The vast majority of commercial building owners will likely not be required to report.  For commercial operations, over 75 percent of buildings have combustion equipment less that 1 mmBtu/hr.  When it comes to commercial buildings having boilers for heating water and steam, approximately 80 percent of the buildings have boilers less than 10 mmBtu/hr.  These are well below the threshold for aggregate maximum rated heat input capacity of the stationary fuel combustion units of less than 30 mmBtu/hr.  If a commercial building does have an aggregate maximum rated heat input capacity equal to or greater than 30 mmBtu/hr, then that facility will need to do further calculations to determine if it meets the threshold for reporting.  EPA has developed an on-line applicability tool to help facilities assess if they are required to report. This tool is available on the Greenhouse Gas (GHG) Reporting Rule Website.
