The 2016 ASHRAE Handbook—HVAC Systems and Equipment will begin being mailed to members in May. To ensure proper delivery, members are encouraged to check their ASHRAE online profile at the "My Membership" page prior to April 15 to verify their mailing address. In addition, if members have not paid their annual dues, they are encouraged to do so by May 31 to ensure they receive a Handbook. Dues can be paid online on the "My Membership" page. Members entitled to receive the ASHRAE Handbook can choose a one-year subscription to the Handbook Online with CD package as their benefit instead of the print/CD combination in place for many years. Another option is the print/CD/online package—a combination of all three formats—for an additional cost.
