"The HVAC system at 350 Mission [San Francisco] aims for top marks in both energy efficiency and occupant satisfaction."

Data Centers and Ab/Adsorption Chillers

Engineered Systems, Apr. 2016, by Marcia Karr.
http://www.esmagazine.com/articles/97665-data-centers-abadsorption-chillers

"A few circumstances in a data center make it ripe for a CHP design to boost efficiency. Let’s get into the options within both relevant chiller types, why payback may be shorter than expected, and the assorted potential benefits from lower costs to higher reliability. Some tips from an array of manufacturers’ reps round out this useful investigation."

Next Step Homes Phase 1: Savings Validation

Northwest Energy Efficiency Alliance, Apr. 21, 2016.
http://neea.org/docs/default-source/reports/next-step-homes-phase-1-savings-validation.pdf

"The Northwest Energy Efficiency Alliance is leading a regional effort called Next Step Homes. The program encourages the design and construction of homes that are capable of achieving energy efficiencies significantly greater than required by current code. Energy 350 conducted a savings validation study for the 12 homes constructed in Phase I of the program."

Measuring the True Costs and Benefits of Energy Storage, Part 2

North American Clean Energy, Mar/Apr 2016, by Katherine Von Burg.

"Part Two - How cycle life and environmental factors impact LCOE
In last month’s issue, Part One of this series began covering how checking a few simple performance metrics can help calculate the true costs and benefits of competing energy storage systems. Additionally calculating this levelized cost of energy (LCOE) can help distinguish between what might look like a good price up front from what’s actually a better buy in the long run."

Tuthill Optimizes Vacuum and Blower Systems for Food Plants

Blower & Vacuum Best Practices, Apr. 2016, by Clinton Shaffer.

"Several experts from Tuthill recently spoke with Blower & Vacuum Best Practices Magazine to discuss opportunities for improvement regarding vacuum and blower systems at food manufacturing facilities. During the talks, Adam Crampton, Russ Ristow, and Tim Wilson of Tuthill covered a variety of topics—from the design basics of pneumatic conveying systems, to advanced vacuum optimization opportunities within packaging machines."

Maximizing MWh: A Statistical Analysis of the Performance of Utility-Scale Photovoltaic Projects in the United States

Lawrence Berkeley National Laboratory, Mar. 2015.
https://emp.lbl.gov/sites/all/files/lbnl-1004374.pdf

"This paper presents the first known use of multi-variate regression techniques to statistically explore empirical variation in utility-scale PV project performance across the United States."

Sewage Treatment Plant Retrofits Diffusers to Cut Energy Consumption 50%

Blower & Vacuum Best Practices, Apr. 2016, by Doreen Tresca.

"In 2012 when the plant was struggling to keep up with regulatory requirements, the Ilmajoki STP [Finland] was using 4000 kWh per day. Once the new diffusers and control systems were implemented, the plant was able to reduce their consumption and averages to under 2000 kWh per day."

Managing Energy as an Ingredient at General Mills

Blower & Vacuum Best Practices, Apr. 2016, by Clinton Shaffer.
http://www.blowervacuumbestpractices.com/industries/food/managing-energy-ingredient-general-mills

"Within the “zero-loss” culture at General Mills, plant personnel identify and optimize major energy users in each facility. Common opportunities include: the optimization of dryers, ovens and freezers; compressed air optimization projects; improvements to building heating and cooling system; and lighting replacement innovations. In addition, engineers at General Mills have started to explore new energy-saving opportunities within the vacuum and blower systems at their production facilities. To better understand how any production system is addressed at General Mills, an examination of the company’s energy management methodology is required."

New Plant Design Options Expand Geothermal Power Operations

Power Magazine, Apr. 2016, by Allie Nelson.
http://www.powermag.com/new-plant-design-options-expand-geothermal-power-operations/

"Geothermal energy may not be a large contributor to the U.S. power mix—it provided less than 0.5% of total U.S. generation in 2015—but it is a reliable and dispatchable renewable energy source that plays well with others. And while the concept is old, new technology is making it easier for grid operators to utilize this important resource."

Lifting the High Energy Burden in America’s Largest Cities: How Energy Efficiency Can Improve Low Income and Underserved Communities

American Council for an Energy-Efficient Economy, Apr. 20, 2016, by Ariel Drehobl and Lauren Ross.
http://aceee.org/sites/default/files/publications/researchreports/u1602.pdf

"Energy burden is the percentage of household income spent on home energy bills. In this report we measure the energy burden of households in 48 of the largest American cities. We find that low-income, African-American, Latino, low-income multifamily, and renter households all spend a greater proportion of their income on utilities than the average family. We also identify energy efficiency as an underutilized strategy that can help reduce high energy burdens by as much as 30%. Given this potential, we describe policies and programs to ramp up energy efficiency investments in low-income and underserved communities."
