USGBC Collects LEED Data to Measure Prediction Gaps
The U.S. Green Building Council on Aug. 26 launched the Building Performance Initiative, which is designed to create a comprehensive data collection effort from all buildings that have achieved LEED certification; implement an appropriate analysis methodology of that data; and provide feedback to building owners so they have better information with which to address any performance gaps that stem from predicted versus actual building performance.
"This initiative is about gathering knowledge about building performance in a way no one has ever done before," said USGBC LEED Senior Vice President Scot Horst. "The information that we collect from our certified projects is a workable, holistic approach for achieving better performing buildings."
Horst noted that the LEED green building program was created to transform the way buildings traditionally have been designed and constructed with the goal of reducing the building's impact on the environment by being more energy, water and resource efficient, but a building's day-to-day operation has a dramatic impact on its performance. Without better information, an owner or facility manager won't know where the gaps are and be able to act on them.
Numerous things affect the ability of a building to deliver high performance, including energy modeling tools, properly timed energy models, quality building commissioning, proper goal setting/benchmarking, and coordination between design and operation. The biggest issue by far is how the people use the building day to day: Do they forget to turn out the lights when they leave the room? Leave the water running in the sink? Do the facility managers have protocols for checking automatic controls? Do they know when those controls are malfunctioning?
"Plenty of people are content to simply point to these longstanding issues without offering a constructive way to address them. We're going to take them on and engage practitioners and thought leaders alike in establishing a national roadmap to optimize building performance," continued Horst.
That engagement mechanism is four Building Performance Initiative summits to be held across the United States in September and October. Participants will have a chance to preview USGBC's data collection agenda and proposed analysis methodology and provide other feedback.
"The local summits are a way to gather people's input for our vision and also for them to share their performance stories, successes and challenges," said Horst.
The inputs from these meetings will be reported on at the First Annual Building Performance Summit at Greenbuild, Nov. 11-13 in Phoenix. An important part of the Building Performance Initiative includes collecting data from thousands of LEED-certified project; USGBC will be working with highly experienced real estate research organizations, including Kingsley and Associates, in this effort.
"Establishing the importance of the connection between the landlord and tenant; the designer and operator; and the owner and the occupant will be one outcome of this initiative," said Horst. "Everyone has a contribution to make to how the building ultimately performs."
