Direct-Fired Technology: From Makeup Air to Space Heating

ASHRAE Journal, Sep. 2015, by Thomas Boeckermann, and others.

"Direct-fired heating technology is a safe, energy-efficient, and cost-effective means to provide heating for a wide range of applications. The two main uses—makeup air and space heating—have different applications and require different approaches to deliver the most efficient design. This article summarizes the basic operating principles, safety, energy performance, psychrometric behavior, and recommendations for the use of direct-fired heating units."

New Fluorescent Lamp Rules to Shake Up T8 Category

Lighting Management & Maintenance (LM&M), Aug 2105, by Craig Delouie. (Scroll to page 24.)

"In January 2015, DOE announced new energy standards for general-service fluorescent lamps, which will take effect January 26, 2018. The new rules strengthen energy standards for 4-ft. T8 linear and 2-ft. T8 U-bend, while both strengthening and expanding covered wattages for 4-ft. T5 and T5HO linear lamps. Eight-foot lamps did not see any change."

Inverter Benchmarking Results in Smarter Residential Inverter Solutions

Solar Industry Magazine, Aug. 2015, by Michael Mills-Price.

"Today’s residential and small commercial solar photovoltaic inverter marketplace includes a myriad of solutions and choices... These products are expected to operate in electrically and environmentally harsh environments, with service lifetimes that can approach and exceed 20 years. The PV inverter landscape is also marked by many new entrants and products from established industry players. These dynamic market characteristics increase the importance of thorough due diligence in the inverter selection process. Independent third-party data can be very beneficial in choosing the optimal inverter solution.

Pond Loop for Ice Refrigeration

ASHRAE Journal, Sep 2015, by Jason Larosh.

2015 ASHRAE Technology Award Case Studies:
"The pond loop geothermal refrigeration system at the Janesville Ice Arena uses an adjacent pond as thermal storage to pull heat from and reject heat to the ice sheet refrigeration system. Other improvements to the arena include a new ice sheet and hot water heating system."

Specifying Acoustical Ceilings in Green Buildings

The Construction Specifier, Aug. 2015, by Kenneth P. Roy.

"Until now, acoustics in commercial office buildings had not been a formal part of the Leadership in Energy and Environmental Design (LEED) rating systems except on a case-by-case basis. The new LEED v4 criteria, however, now takes into account the value of good acoustics in enhancing occupant satisfaction and productivity."

It's All About the Data: How the Building Performance Database is Informing Decisions on Energy Efficiency

U.S. Department of Energy, Aug. 25, 2015.

"Filling a gap in the market, the BPD provides public access to anonymized data on hundreds and thousands of buildings and homes.  Increased access to energy-related information in buildings allows end-users to make key decisions on energy efficiency projects, policies and programs. For the first time, users can compare variables across regional markets, uncover data trends, and draw conclusions that would otherwise be impossible or costly to identify."

Secondary Glazing System (SGS) Thermal, Moisture, and Solar Performance Analysis and Validation

Northwest Energy Efficiency Alliance, Aug. 19, 2015, by Robert Hart, and others from LBNL.

"NEEA contracted with the Ernest Orlando Lawrence Berkeley National Laboratory to conduct a study, from which this report is based, which simulates and physically validates the thermal and solar performance characteristics of seven window attachment secondary glazing systems (SGS), also known as Fixed Window Panels, using industry standard practices. Where industry standard practices do not exist, such as condensation resistance (CR) between base glazing and SGS, this report introduces new methodology and software capabilities. This report also evaluates the annual energy savings and condensation potential of all SGS systems in prototype commercial buildings."

The Utopic Promise of the 'Internet of Things'

Architectural SSL, Aug. 2015, by Kevin Willmorth.

"Buildings demand solid foundations, but where structural foundations need hard earth, upcoming interactive controls need reliable communication."

Air Curtain: Energy-Saving Advancements Open Doors to New Uses

Business Energy, Jul/Aug 2015, by Stephen Benes.{}

"The basic air curtain concept of protecting an open doorway from the exterior environment with and 'air seal' hasn't changed much in the last 50 years, but what has changed is the variety of businesses using them today to save energy."
