Hello <<First Name>>!
We had a fantastic start to our 2011-2012 season with a presentation by our chapter's own Jon Ziegler offering his opinions and insight on the role of test and balancing and specifically how it relates to LEED. We had 30 people attend the meeting and received 12 evaluation forms, with a total point average of 95 out of 100. We really appreciate receiving the evaluation forms as it helps us select future topics and speakers. If you have any topic requests or suggestions please feel free to email me at firstname.lastname@example.org.

Alternative to Standard 62.1 Proposed
ATLANTA – Public comment is being sought on the proposed allowance of an additional default value to the ventilation rate procedure in ASHRAE’s indoor air quality standard.
ANSI/ASHRAE Standard 62.1-2010, Ventilation for Acceptable Indoor Air Quality, sets minimum ventilation rates and other requirements for commercial and institutional buildings. The ventilation rate procedure provides a prescriptive method for determining minimum ventilation requirements. It accounts for pollutant sources from both the building and its occupants, and allows the designer to account for the efficiency of different ventilation systems when delivering outdoor air to the breathing zone.
