The Building Science Consortium held an Expert Meeting on Diagnostic and Performance Feedback for Residential Space Conditioning System Equipment on April 26,l 2010 on the NIST campus in Gaithersburg, Maryland. Featured speakers included Vance Payne of NIST, Haorong Li of the University of Nebraska, William Healy of NIST, Amr Gado of Emerson Climate Technologies, and Roy Crawford of Ingersoll Rand. Key results from this meeting were:

  • Greater understanding of the sensors and controls currently incorporated into HVAC equipment.
  • Greater understanding of the problems which reduce HVAC efficiency, and the sensors needed to detect these problems.
  • Improved communication between HVAC manufacturers and regulating agencies about the possibility of mandating fault detection and diagnostics (FDD)

This meeting summary provides an overview presentations and results.
