"If you’re considering a major retrofit of an existing HVAC system, take these three steps to do your due diligence for a possible VRF [variable refrigerant flow] solution, says Anne Wagner, energy efficiency engineer at the Pacific Northwest National Laboratory (PNNL)." Also, gives a 15-year lifecycle cost analysis comparison between VAV and VRF retrofit alternatives.

How To Reduce Elevators' Energy Use

Building Operating Management, Dec. 2014, by Karen Kroll.

"Elevators’ energy use can be reduced through a variety of means, including the use of more efficient AC motors and regenerative drives, but this objective does not always get top priority."

Slash Plug Loads in 6 Steps

"Plug loads are becoming one of the fastest growing end uses of energy, the New Buildings Institute warns, and their drain on energy budgets is on the rise. [Plug load] includes any devices that plug into a building’s electrical system. In a typical office, the worst offenders are desktop equipment such as computers, monitors, and printers, notes Suzanne Foster Porter, director of research and technical services for ECOVA, an energy and sustainability management firm. Small offices also see a disproportionate amount of their plug load stemming from IT closets and computer rooms."

LED Lighting Makes Pro, Trains For Super Bowl Debut

"This year’s Super Bowl will the first played under energy-sipping LED lights. The University of Phoenix Stadium, host to the Feb. 1 game, uses 312 fixtures made by Ephesus Lighting, which specializes in technology for fields, arenas and the like. The lights replaced 780 metal halide fixtures."

5 Ways to Maximize Your Economizer Efficiency

Buildings, Jan. 2015, by Jennie Morton.

"Is your air conditioning bill running wild? Get your utility costs under control by adding an air-side economizer. This device draws in outside air as a form of free cooling. While the potential for savings is significant, facility managers can lose all of an economizer’s benefits if they fail to specify the right features and neglect maintenance. Follow these tips to lock in your economizer’s potential."

Doubling Energy Productivity by 2030

"While energy efficiency remains at the forefront of trends impacting the HVACR industry, it’s not only efficiency that the industry — and country — needs to be thinking about. We also need to address energy productivity: increasing GDP while reducing energy use."

Multiple Benefits of Business-Sector Energy Efficiency: A Survey of Existing and Potential Measures

ACEEE, Jan. 2015, by Christopher Russell. (Need to register to view full-text.)
http://www.aceee.org/sites/default/files/publications/researchreports/ie1501.pdf

"Businesses [large commercial, industrial, and institutional] that implement energy efficiency improvements often enjoy other benefits besides utility bill savings. However previous efforts to measure multiple benefits have been sporadic and far from rigorous. Still, evidence suggests that including non-energy impacts can reduce the payback time of some energy efficiency improvements by 50% or better. This report draws on expert interviews and a synthesis of existing literature to describe energy efficiency’s multiple benefits to business enterprises."

Seattle Municipal Buildings: 2012-2013 Energy Performance Report

City of Seattle, Dec. 2014.
http://www.seattle.gov/Documents/Departments/OSE/2014-12-11%20EnergyPerformanceReport_2013_FINAL.pdf

"The City of Seattle has set an ambitious target to be a carbon neutral community by 2050. To get there, the entire community needs to reduce its environmental impact and City government must be a leader and an active participant. This report demonstrates that leadership by publicly sharing the results of the City’s work to rate the energy efficiency, or "energy performance" of City-owned facilities."

Energy Efficiency: The Secret Revolution

Solutions Journal, Rocky Mountain Institute, Summer 2014, by Amory Lovins.

"How low can we go in the efficiency limbo? Nobody knows — but we’re far from any practical limit, and the frontiers keep expanding. Every gain in smart thermostats and superwindows, in LEDs and motors, in process equipment and computers, locks in more “negawatts” that further reduce our energy intensity."

Report: Utility Spending on Energy Efficiency Soars as Supportive State Policies Are Expanded

Power Magazine, Dec. 2014, by Sonal Patel.
http://www.powermag.com/report-utility-spending-on-energy-efficiency-soars-as-supportive-state-policies-are-expanded/

"Electric utility spending and budgets for customer-funded energy efficiency programs have seen a 30% boost compared to 2010 levels and could double by 2025, thanks to expanding state policies, an updated report from the Institute for Electric Innovation (IEI) suggests."
