AGRICULTURE (URBAN)

Farming the Heavens(go to page 59) was written by Wyatt C. King, Director, Albright Stonebridge Group. It describes the vertical farming (greenhouses that are several stories high) that is part of the urban-agriculture movement. The example covered is in Singapore which, currently, imports 90 percent of its food.

BUILDING SCIENCE

Taking Control(go to page 12), by staff, is the journal’s annual review of best building practices. It includes discussions of insulation, ventilation, electric heating, and ducts. Specific attention is paid to the differences between multifamily and single family buildings that necessitate different approaches to optimize each.

GREEN ROOFS and WALLS

Going Green Improves Energy Consumption, Air Quality,” by Chrissy L.S. George, NEMA Communications, includes discussion of heat islands, two types of green walls, and more. It shows the connection between those and energy savings.

HVAC/R (HEATING, VENTILATION, AIR CONDITIONING, AND REFRIGERATION)

LIGHTING

Shedding Light on Retrofits,” by Elizabeth Smyth, appeared in the August 2013 issue of Interiors & Sources. She reports that most (82 percent) pre-1980 buildings in the commercial sector “are using the same lighting technology now that they have used for the past 30 years.” She discusses the basic choices that can be made to make a lighting retrofit an excellent option.

MOTORS

Global Motor Labeling Program Provides Consistency in Successful Motors Initiative” was written by Daniel E. Delany, Agency and Standards Manager, Regal Beloit America Inc.; it was published in the August 2013 issue of NEMA's electroindustry. The Global Motor Efficiency Labeling Program alleviates the problem that motor manufacturers face when having to respond to energy-efficiency requirements that differ from country to country.

PELLETS

Preparing for a Pellet Tide” by Tim Portz, Executive Editor, Pellet Mill Magazine, shows that in England, pellets are replacing coal for heating. The author describes the conversions of coal plants to pellet ones.

RESIDENTIAL EFFICIENCY STRATEGIES

"Fall and Winter Energy-Saving Tips" is a Web page from the Energy Efficiency and Renewable Energy Office of the U.S. Department of Energy. The site is now offering many tips for energy savings for the cooler months.

WIND

Stopping Repeat Wind-Farm Generator Failures,” by Randall Noone, PE, was published in the September 2013 issue of Maintenance Technology. It is a case study of generator failures on one farm and includes a thorough investigation into the causes of the failures, an examination of the problems found, and a successful maintenance solution put into place.

The following three articles were carried in the August 2013 issue of North American Windpower:

  1. As Towers Grow Taller, Consider Structural Impacts,” by Dilip Khatri, Founder of Khatri International, reports that towers have more than doubled in height and turbines are approaching eight times the capacity of older ones. The effects of these increases on structural integrity, soil stability, and frequency response are discussed.
  2. Understanding and Assessing Subsynchronous Resonance,” by Steven W. Saylors, Senior Specialist of Electrical Engineering at Vestas, explains the damage that subsynchronous resonance (SSR) can do, with particular attention to the different types of SSR.
  3. Using Anchor Foundations in Difficult Soil Conditions” was written by Horst Aschenbroich, President and CEO of Delta, British Columbia-based Con-Tech Systems Ltd. When spread-reinforced concrete footings cannot do the job, there are alternatives that can: micropiles. There are different ways to install them, depending on the application.
