COMMENTARY
Where ASHRAE Is Going
Driving the buildings industry to new levels of sustainability has been a core value at ASHRAE for many years. You can see this in the standards, publications, conferences and almost everything ASHRAE does. Maintaining the sustainability of ASHRAE as a viable force in the industry also is important, said new ASHRAE President Ron Jarnagin in his presidential address in Montreal. His presidential theme is Sustaining ASHRAE Through Leadership. This will take a new generation of leaders, he said. And it also will mean that ASHRAE needs to engage in activities that position it as a global leader, and use its leadership to strengthen the industry. “I think it’s important for us to try to set goals and engage in those Fred Turner activities that will make this organization strong in the future,” he said. Jarnagin is a staff scientist at the U.S. Department of Energy’s Pacific Northwest National Laboratory (PNNL). He has chaired a number of technical groups, including ASHRAE Standard 90.1, and has held every Executive Committee office. A text of his speech starts on Page 18 and is important reading for ASHRAE members and the industry as a whole. THE AVERAGE age of U.S. commercial buildings is 41.7 years and 15% are more than 75 years old. This is why you should read “Retrocommissioning Older Buildings” by Dave McFarlane, Member ASHRAE. The article covers the types of systems in vogue in the 1960s through the 1980s, and likely problems and solutions. He also provides calculations for energy savings, which can be substantial. “This article,” he writes, “deals with buildings built when energy was cheap and fuel supplies seemed never-ending.” This edition also includes the final installment of an excellent 12-part series on the construction and monitoring of the Equinox House, a net zero energy house near Chicago. The authors are Ty Newell, Member ASHRAE, and his son, Ben, Associate Member ASHRAE. This installment reviews the life-cycle costs for major elements such as windows, insulation, solar photovoltaic systems and infiltration. The entire series is available at www.ashrae.org/solarNZEBproject. IN OTHER articles and columns: Stan Mumma, Ph.D., P.E., Fellow/Life Member ASHRAE, writes about common misconceptions with dedicated outdoor air systems. An article on industrial refrigeration covers the use of centrifugal pumps to pump refrigerants. The authors are Todd Jekel, Ph.D., P.E., Member ASHRAE, and Doug Reindl, Ph.D., P.E., Fellow ASHRAE. We also have two excellent Technology Award case studies and a complete lineup of departments and standing columns. Joe Lstiburek is taking a break and will return in September. Let us know what you think. Your feedback is important to us.
