Identifying motor retrofit opportunities in cooling towers, air handlers, exhaust fans, and
circulating pumps reflects the no-stone-unturned strategy Rutgers employs in energy management.For those motors, boiler upgrades, and future projects, the university regularly seizes on multiple incentives opportunities — ranging from utility offers to good old-fashioned intraschool competition — to teach efficiency in action.
Texas Women’s University found that continuous energy monitoring and verification paid off well, yielding savings above and beyond an existing performance contract. The authors explain how measuring and managing can defeat the usual suspects that drag down plant performance. Is yours hiding some untapped greatness?
Although it’s the second-oldest college in America, the College of William & Mary boasts the oldest college building in the United States, the Sir Christopher Wren Building, which was built in 1695 before the founding of nearby Williamsburg, VA. Now fast-forward to the 1960s, when the college expanded to accommodate Baby Boom students.
Patrick Baldwin-McCurdy fields daily indoor air temperature requests from employees and students, but Seattle University’s (SU) lead buildings control technician rarely hears HVAC complaints from the college’s new library addition featuring under floor air distribution (UFAD).
Designing a new high school to be 40% more efficient than ASHRAE 90.1 – 2001 energy requirements is a feat in itself. To achieve this degree of efficiency on a very limited capital budget while designing a state-of-the-art, energy-demanding technical high school is an even greater feat.
Energy efficiency and historic preservation are rarely synonymous. More often than not, one must be compromised for the sake of the other. Fortunately, the University of Arkansas found a way around such compromises when it came to the restoration and mechanical renovation of the school’s beloved Peabody Hall.
Effective building envelope and air handling designs took comfort most of the way from theory to reality in ISU’s Hach Hall. An existing in-house deionized water supply and a new fogging system finished the task and saved an estimated 22% in humidification costs.
This past March, I asked the question, “Do you have a corporate sustainability plan?” and recently I was discussing this topic with a director of a physical plant for a major college on the East Coast. He commented, “Energy conservation and environmental management should be a team effort.”
“Not enough airflow.”
These were just a few of the countless complaints that facilities managers of the Basic Medical Science Building at the University of New Mexico were receiving on a regular basis.
Retrieving every last bit of performance from the system while stopping short of the surge line is no small feat. Dig into sizing, tower selection, chilled water loads and stability, and condenser water management to leave no efficiency stone unturned. Read more in April issue
