Inquiry

We have three questions related to compliance with the second part of this Credit\'s requirements in spaces where chemical use occurs: 1. Our typical strategy involves providing structural deck-to-deck partitions, as well as separate outside exhausting which will create negative pressure. The applicable spaces will not have supply ductwork, but will draw supply air through the small undercut in the door. Does this meet the Credit Requirements for physical isolation of the space? 2. In spaces where chemical use occurs, is it sufficient for the exhaust system to be tied to a switch with a requirement that the user turn it on during the chemical use, or must the exhaust be continuous? 3. A Credit Ruling dated 7/22/2003 included "common laundry rooms" as housekeeping areas where chemical occurs. Laundry rooms typically have both washers and dryers. When a laundry room is in use, the dryers are typically in operation, which draw room air out through their individual exhaust systems. Assuming this measure is submitted under LEED 2.0, will the dryer exhausts meet the requirements for a laundry room, or must the exhaust system be provided in a different manner?
