Registration for the 2015 ASHRAE Webcast, “New Tomorrows for Today’s Buildings: Existing Building Commissioning,” is now open at There is no fee for registration.

The webcast, offered by ASHRAE’s Chapter Technology Transfer Committee (CTTC), is broadcast live on April 23, 2015, from 1 p.m. to 4 p.m. EDT. The webcast features industry experts who will define the benefits of existing building commissioning for the environment, occupants, operations staff, and overall ownership costs.

“The presenters will distinguish between new building commissioning, existing building commissioning, and retro-commissioning,” said Nathan Hart, chair of the CTTC Webcast Ad Hoc Committee. “Viewers will learn how to manage the commissioning process to minimize the impact on building functions and occupants, and how to integrate elements of existing building commissioning into the operation and maintenance staff’s daily activities. The focus will be on maximizing energy efficiency and return on investment.”

The webcast presenters are:

• Bob Baker, Fellow ASHRAE, OPMP, managing director, BBJ Consulting in Riverview, FL

• Jim Vallort, Fellow ASHRAE, practice leader, Environmental Systems Design Inc. in Chicago, Ill.

• Ron Wilkinson, P.E., CPMP, commissioning authority, Wilkinson Commissioning Management in Seattle.

The webcast has been approved for three Learning Units (LUs) by the American Institute of Architects (AIA) and three Continuing Education Units (CEUs) by GBCI. The state of New York also recognizes AIA course approval.
