"Robin Roy, an NRDC consultant, explains why community energy storage often falls between the gaps in federal energy policy and what can be done about the problem."

Comparing Polystyrenes: Looking At the Differences Between EPS and XPS

The Construction Specifier, Sep. 2016, by Jason Burgess.

"Insulation is a critical component to specify when designing a functional, cost-effective, and energy-efficient building. One method to insulate a building is by installing 50 to 152 mm (2 to 6 in.) of rigid foam insulation on the exterior side of the wall framing. Two of the most frequently installed types of rigid foam insulation are expanded and extruded polystyrene (EPS and XPS). Both serve the same basic function: providing a means to manage the passage of heat in a building system. However, they differ in important ways."

Net Positive Energy Buildings

ASHRAE Journal, Aug. 2016, by Dylan Connelly and Laura Fedoruk. (Article Summary only.)
https://www.ashrae.org/resources--publications/periodicals/ashrae-journal/features/net-positive-energy-building

"DPR Construction’s retrofitted San Francisco headquarters building achieved approximately 20% net positive energy its first year of operation using efficient systems including HVAC, electrical and PV. And, in late 2015, it was certified as a net zero energy building. The office building demonstrates the capabilities of integrated, innovative, and replicable design. And, it proves that sustainable buildings can reduce energy use and improve indoor environmental conditions, while being cost effective. It has become a hub for learning and collaborating on many sustainably minded design projects."

Tackling Energy Codes with Energy Modeling: Preparing Design Professionals to Face Building Performance Demands

Building Codes Assistance Project for the Energy Foundation, Aug. 2016.

"This paper intends to map the existing landscape of building energy codes and modeling software, highlighting current best practices and identifying steps for removing barriers. "

Proving its Long-Term Mettle: Longevity, Whole-Building LCAs, and Stainless Steel

The Construction Specifier, Aug. 2016, by Catherine Houska.

"Whether the project is a new building or major renovation, sustainability is an increasingly important factor in decision-making. Whole-building life cycle assessment (LCA) makes it possible to look at all phases of a building, from material extraction through construction to decommissioning and, when possible, recycling into a ‘new’ useful material. When it comes to comparing materials, increasingly available data, an ASTM standard procedure, and LCA analysis software are helping design professionals make better choices to reduce the building’s carbon footprint."

Package Boilers Find New Friends

Plant Engineering, Jul/Aug 2016.
http://www.plantengineering.com/single-article/package-boilers-find-new-friends/6dff20bf020db5486b2b87a3b6963077.html

"For original equipment or replacements, package boilers offer efficiency, redundancy, flexibility: Advanced controls manage steam ramp-up and ramp-down for better combustion efficiency and heat transfer; improvements create efficiencies as high as 85%."

Innovations in Motor Technology Spark Energy Efficiency

Business Energy, Jul/Aug 2016, by Patrick J. Piper.
http://foresternetwork.com/business-energy-magazine/be-energy/be-energy-efficiency/innovations-in-motor-technology-spark-energy-efficiency/

"With minimum efficiency regulations increasing two to three times every decade, the engineering preference to make motors more efficient is coming to the fore. Motor manufacturers have been trying to improve the efficiency of their motors for years, however there hasn’t been a new technology to rival ECM motors in efficiency and performance."

Regulation of Commercial Fan Efficiency: An In-depth Exploration of the Department of Energy’s Fan and Blower Rule

Business Energy, Jul/Aug 2016, by Trinity Persful.
http://foresternetwork.com/business-energy-magazine/be-energy/be-energy-efficiency/regulation-of-commercial-fan-efficiency/

"Fans consume 14% of the electricity purchased by industrial and commercial buildings. Yet, fan efficiency has escaped the attention of those who design efficiency into the air systems they specify. That is about to change. The US Department of Energy (DOE) will publish their proposed rule this year covering fans from 1 to 200 horsepower. This new regulation will determine compliance at the design point of the fan."

Update on U.S. Fan Energy-Efficiency Regulation

Heating, Piping, Air Conditioning Engineering, Aug. 2016, by Anthony (Tony) Rossi and Michael Wolf.
