Editor's Notes
- - The 1980’s introduced PC (DDC) controls to commercial real estate. 1 building, 1 computer, 1 vendor - DDC systems derived from DNA of analog pneumatic & electric controls. 1 building, 1 computer, 1 vendor - Multiple, competing, hardware and software platforms (85+) and communications(15+) protocols. 1 building, 1 computer, 1 vendor - 2000-2010 market consolidation as major vendors; Honeywell, Johnson, Siemens and Schneider buy and aggregate competition result: 1 building, 1 computer, 1 vendor - 2010-today .. An explosion in cloud computing tools means DATA is now your sensor and you can unlock your building’s operational profile independently: any building, all vendors
- I work within Office of Facility & Project Management, which is a division of our Business and Finance area. I’m going to quickly cover a few important pieces of context relating to our energy reduction efforts. Buildings – variety of construction and use types, ages (1893 oldest, 2014 newest), conditions Motivation / rationale: Mission – engaging the culture, changing the world Financial – primarily tuition funded (money should go back into student experience rather than utility bills), manage risk of fluctuating energy prices
- Our baseline carbon footprint is fairly typical for Seattle, with transportation and building energy use comprising the largest portions. We chose to prioritize natural gas reduction in the short term because we have a greater degree of control over building energy use than commute footprint. Our primary initial goal was a 20% reduction in natural gas consumption between 2010 and 2015.
- Some quick math - Given that our annual natural gas consumption is roughly half a million therms, our job was to come up with a way to reduce campus natural gas use by about 100,000 therms Our strategy for this reduction was to prioritize energy efficiency in new development while managing separate projects to better capture and respond to information about energy use in our existing buildings. This included additional meters, improved building controls, retrocommissioning, and implementing recommendations developed through the retrocommissioning process.
- We initially estimated that we could achieve a 12% natural gas reduction with the items in blue background, and an 8% reduction would come via planned development (or major renovations that would replace some of our older campus mechanical equipment). Due to changes in our administration, our development priorities shifted. Combined with new property acquisition, it turned out that our 20% natural gas reduction would need to come almost entirely from our measurement and retrocommissioning efforts.
- A quick note on funding mechanism – while we do anticipate roughly 15% of total project cost coming from utility incentives, the bulk of funding for this effort comes from internal borrowing paid back through utility savings. This allows us to make a larger initial investment in saving energy, and it incentivizes us to maximize energy reductions. I.e. The sooner we get our energy management budget back in the black, the sooner we can use it to fund other projects.

- Retrocommissioning (RCx) is a systematic process for identifying less-than-optimal performance in your facility's equipment, lighting and control systems and making the necessary adjustments. While retrofitting involves replacing outdated equipment, RCx focuses on improving the efficiency of what's already in place.

- Unlock data to manage energy in Real Time – Through a partnership with Seattle’s Smart Buildings Center, SPU pilotedBuildpulse, a smart sensor energy monitoring and management system. Leveraging the existing smart sensors and submeters installed previously at the SPU campus, the Buildpulse hardware captures system and building level performance data real-time with a granularity down to 15 seconds for all buildings. This data is then sent automatically to an online dashboard, providing real time visibility into the portfolio’s performance and ultimately streamlining the benchmarking process.
