The American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) will be presenting two free sessions at the AHR Expo in Las Vegas. “A Practical Guide for Reducing Air Leakage in HVAC Air Systems” will take place Monday, Jan. 31, from 2:15 to 3:45 p.m., while “Standard 90.1-2010 Update: How It Affects You” will be conducted on Tuesday, Feb. 1, from 2:15 to 3:45 p.m. Attendees can earn 1.5 professional-development hours for each session.


“Practical Guide” will focus on how excessive air leakage in HVAC systems is known to be a significant source of energy waste. This session will identify the current standards, guidelines, and project specifications that influence air leakage and highlight the roles and responsibilities of engineers, contractors, and manufacturers.

The Tuesday session will provide an update on ANSI/ASHRAE/IESNA Standard 90.1-2010, Energy Standard for Buildings Except Low-Rise Residential Buildings. With more than 100 addenda incorporated since the 2007 edition, this session highlights some of the major changes in the 2010 standard.



The 2011 ASHRAE Winter Conference is being held in conjunction with the AHR Expo from Jan. 29 to Feb. 2 in Las Vegas. Additional courses and sessions will be offered through the Conference’s Technical Program and the ASHRAE Learning Institute. More information can be found at www.ashrae.org/lasvegas.
