Where did the 7-point scale requirement come from? We have had our documentation questioned in reviews because we did not use this scale.

Our project is not able to show compliance with the requirements if IEQc7.1, but has still installed a permanent monitoring system and the owner has agreed to conduct occupant comfort surveys every 6 months. Since we will not be eligible to achcieve IEQc7.2, can these strategies qualify for an innovation point instead? Please advise. Thanks!

Lance, I have not tried this myself but it is certainly worth a try. Keep in mind there is a requirement of corrective action if survey responses show that more than 20% of occupants are dissatisfied. This baseline for the corrective action is based on an ASHRAE assumption that even when following the standard up to 20% of occupants may still be dissatisfied. Depending on the occupant culture and building location, the theory is that your dissatisfaction rate may be higher, requiring corrective action. It also poses a fundamental question of whether you can ensure occupant comfort without meeting the standard. Though as long as the owner is committed to the potential corrective action required, you are going above and beyond what is required, warranting a case for innovation. Let us know how it goes!

My sense is that it will not be accepted. Since you cannot meet EQc7.1, a survey is likely to show that comfort conditions are not being maintained. Then what?
