"Air-flow testing should be done with the room dampers completely open and room doors completely closed. If test results deviate slightly from the design air-flow rates, adjust the balancing dampers and retest. If test results deviate considerably from the design air-flow rates, ductwork may be crushed, punctured, or obstructed. Work with the HVAC contractor to fix the problem."change to "Performance testing is important for identifying any equipment failures or installation problems. HVAC contractors should conduct their own performance testing, but this does not qualify as third-party testing for the purposes of EQ 6.3.Third-party testing must be performed by a qualified energy rater, Green Rater, or a third-party testing and balancing company. If test results deviate significantly from the design air flow rates, ductwork may be crushed, punctured, or obstructed. In this case, the HVAC contractor should investigate and fix the problem. Once the problem is fixed, the air flow rates must be re-tested and the requirements of the credit must be met before EQ 6.3 can be awarded."Air-flow testing should be done with the room dampers completely open and room doors completely closed.
