During the construction phase a contractor has painted a wall with high VOC paint. What is the process to use to correct the error or submit information to qualify for Indoor Environmental Quality Credit, Low-Emitting Materials-Paints and Coatings?
A: Subtract the high VOC paint from any calculations
B: Subtract the high VOC paint from the design case calculations
C: Include the volume of high VOC paint in both the baseline and design case VOC calculations
D: Paint over the high VOC paint with an approved low VOC paint

参考答案: C

VOC budgets require a baseline and design case.

Suppose we use 20 gallons of paint on a project (to keep the math simple). A nonflat coating has a current limit of 150 VOCs. The baseline case would be 20 gallons X 150 VOCs = 3,000 VOCs.

The project uses 10 gallons of paint that have 300 VOCs and exceed the VOC limit. These 10 gallons have a design case of 3,000 VOCs

The project also uses 10 gallons of paint that have 0 VOCs. These 10 gallons have a design case of 0 VOCs.

The total design case VOCs would be 3,000 VOCs + 0 VOCs = 3,000 VOCs.

The design case has not exceeded the baseline so the credit would be earned.

Painting over the high VOC paint with a lower VOC paint doesn\'t reduce the emissions of the high VOC paint and could end up exceeding the VOC budget (at least in this example).
