Editor's Notes
- #5: ZEC Zero Energy capable.
- #6: NREL = National Renewable Energy Laboratory SMUD = Sacramento Municipal Utility District
- #9: Model is within 1% of reality
- #13: Our project looked at an expansion and extensive remodel of our North Satellite, built in 1970 with an EUI of 282.油 The firm doing the study designed one of the first net zero office buildings in the United States, the Bullitt Center Foundation in Seattle.油 Terminals are a different building type and operational use.油 Connected to our central utility plant, the best we could get to was an EUI of 97 (with strategies for high performance building envelope, high performance mechanical with chilled beams, daylighting, geothermal, and improved controls).油 Decoupled from our central utility plant, with the same strategies, we could get to an EUI of 72.油 These are significant improvements for energy efficiency, but not net zero.油 PV does not provide much opportunity within the envelope of the North Satellite in our climate.油 For airports like SEA, most of the opportunity for energy savings will be through terminals, which use the most energy per square foot compared to other building types (parking, cargo, maintenance, hotel).油 SEA, like many airports, has a significant square footage of existing building stock that will not be going away anytime soon.油 Repurposing the building stock to be more energy efficient offers great opportunity.油 By repurposing existing building stock to be more energy efficient when we replace aging systems, and setting appropriate targets for new bulding stock, SEA can add 50% square footage of buildings to the airport campusand reduce energy use by 25% from current levels.
- #15: John Rogers, of the University of Illinois, Urbana-Champaign has devised solar cells (which are being made, packaged into panels and deployed in pilot projects by Semprius, North Carolina) which convert 42.5% of sunlight. Even when surrounded by the paraphernalia of a panel they manage 35%. Suitably tweaked, Dr Rogers reckons, their efficiency could rise to 50%. Their secret is that they are actually not one cell, but four, stacked one on top of another. The Economist
