Fortunately, Cornell has a 10 year history of progressive management of laboratory ventilation operations. Each building on campus is metered for a variety of types of energy use and data for tracking the impact of building changes is readily available on the Facilities Services web site. Preventative maintenance activities in laboratory buildings are organized around the concept of ‘‘continuous commissioning’’ of laboratory rooms to assure that the ventilation is operating within an appropriate range of pressure differentials and flow rates. In light of this, we were able to connect our newly developed Laboratory Ventilation oversight program with the Energy Management program by choosing four key indicators to monitor lab ventilation system operations; two of these represent safety concerns and two represent sustainability issues. Figure 4 is a diagram of how the two programs are connected within the PDCA framework of the ANSI Z10 standard.
