Seattle Public Schools is the largest school district in Washington comprising about 100 schools, 55,000 students and 6,300 full time employees. Energy efficiency has been a School Board priority for years, allowing us many years to perfect best practices to operate our buildings. Our buildings are eclectic to the extreme, with all ages, sizes, envelops and HVAC systems represented. We maintain buildings with high rates of turnover for principals, teachers, students and Custodial Engineers. Many factors increased energy demands, from huge increases in student populations, to leadership changes, to expanding technologies, to surging community user’s demand for building use permits. Yet our energy use has been stable for a decade with an EUI average of 40.. How? With dedicated monitoring of energy management controls, solid temperature setpoints, tight scheduling, and strict adherence to EUI goals in new buildings design. We will discuss what we do to get and keep low Energy Use Indexes throughout our buildings. Then we’ll discuss our new procedures to take the time to examine each building closely to find and fix problems. This in-house retrocommissioning has shown that even well-run buildings have savings opportunities. The key has been to investigate, educate and document. The retrocommissioning program was many years in the making. Four Retrocommisioners comb through buildings and ratchet up our game. They report to senior Mechanical Coordinators with expertise in building operations and Capital Improvements. We will walk through their (speeded up) process and explain how they tackled findings both expected and unexpected. We will reveal our strategies and detail our procedures. Our success has been dependent on building and maintaining good working relationships with the Mechanical Coordinators, and with other departments, especially Capital Planning and Construction and Facilities Operations. We partner with Puget Sound Energy, Seattle City Light, the Lighting Design Lab, NEEA, PNNL and IDL to maximize our results. We will share suggestions, and offer a few warnings about what to avoid and how to improve designs that result in situations where there will not be solutions for improvement.
