"Profiles of three new data centers—Orlando Health in Florida, Avnet Inc. in Arizona, and BendBroadband in Oregon—illustrate the revolutionary changes that have improved data center energy efficiency and return on investment."

A Penny Saved... Recent Advances in HVAC System Controls and Operational Efficiency

"A properly operating heating, ventilating, and air-conditioning (HVAC) system is a lot like a football lineman. When it is running perfectly, you don’t even know it is there. Recent advances in efficiency, operating controls, durability, and “smart” applications can make your HVAC system even more unnoticeable."

Seattle Building Energy Benchmark Analysis Report, 2011/2012

Seattle Office of Sustainability & Environment, Jan. 2014.
http://www.seattle.gov/Documents/Departments/OSE/EBR-2011-2012-report.pdf

"Seattle is currently one of nine cities and two states in the nation that have enacted energy benchmarking disclosure policies aimed at increasing energy efficiency in the existing building stock through data access and transparency. In 2013, Seattle completed the Energy Benchmarking and Reporting program ramp-up phase by collecting whole-building annual energy use for commercial and multifamily buildings 20,000 square feet or larger. This first report summarizes program outcomes, building characteristics, trends, and recommendations."

Super Bowl's Green Stadiums: MetLife and Others Tackle Energy Efficiency

National Geographic, Feb. 1, 2014.

"MetLife Stadium will light up in bright orange, blue, and green lights when the Denver Broncos play the Seattle Seahawks on Sunday.  The striking display that rings the top of the stadium is powered by LED light bulbs, which are already energy-efficient—but they are made even more so by the power source that runs along the same track. The 1,350 solar panels installed on the ring can generate enough electricity to power the colorful lights and other operations."

Innovation in Building Energy Efficiency Puts Seattle in National Leadership Spotlight

Northwest Energy Efficiency Council, Jan. 27, 2014.
http://www.neec.net/news/neec-press-release-innovation-building-energy-efficiency-puts-seattle-national-leadership-spotl

"Pay for Performance (PfP) is an innovative pilot project from Seattle City Light designed to test a new way to calculate the utility financial incentive and to provide more surety that the project delivers energy savings year over year. PfP offers the chance for building owners to receive a greater incentive than what they get under the traditional system, if they can show more than predicted measured and verified savings at the meter. For Seattle City Light, it reduces the utility’s risk in actually receiving the savings for which they are paying."


World Changing Ideas

Green Builder, Jan. 2014.

"With help from our friends at Sustainia, here's a list of 25 of the most powerful technologies and ideas that will soon change our world in profound ways. From gravity powered LEDs to wireless car chargers, these are the good ideas that (we believe) won't go away." Close to half are energy related or have energy implications.

Right-Size Your Ventilation Needs [with DCV]

Buildings, Jan. 2014, by Jennie Morton.
http://www.buildings.com/article-details/articleid/16743/title/right-size%20your%20ventilation%20needs/viewall/true.aspx

"Can ventilation requirements and energy conservation go hand in hand? They can if you implement demand control ventilation (DCV). There’s no reason to waste energy conditioning air for people who aren’t in your building. Instead of supplying air at fixed rates, DCV automatically adjusts ventilation levels based on real-time occupancy measurements. This strategy allows you to meet code and reduce energy use without sacrificing indoor air quality."

Vaunting VRF: An Energy Slashing System Is on the Rise

"While [Variable Refrigerant Flow] VRF has been dominant worldwide for over 20 years, the U.S. has been slow to accept it for several reasons. Products have primarily been manufactured by Asian companies, which at one point had limited presence in the U.S. There is also little critical evaluation of actual field energy performance. But VRF sales in the U.S. are growing and multiple manufacturers offer these systems, including Carrier, Daikin, LG, Mitsubishi, and Sanyo."

"Without a proper site assessment, you may be putting your solar thermal system at risk for poor performance."

Using Duct Surface for Leakage Testing?: Simple Testing Isn’t Always the Most Accurate

Air Conditioning, Heating & Refrigeration News, Jan. 6, 2014, by David Richardson.
http://www.achrnews.com/articles/125242-using-duct-surface-for-leakage-testing

Author questions "the metrics that have been in place for residential duct leakage testing for years. Are they the most accurate metrics to use for determining duct leakage in a residential duct system? Would this be the best metric to use for quantifying duct leakage in residential duct systems?"
