Wind Powered Electric Generation for Your Home or Business  by David C. Young, P. E. Today we realize that wind is a valuable resource we cannot ignore, but wind energy is just one piece in the pie. To fix this energy crisis, we are going to need a lot of conservation plus every alternative energy source we can find. Energy Codes at a Glance   by Pam Cole and Eric Richman  Feeling dim from energy code confusion? The U. S. Department of Energy’s Building Energy Codes Program addresses hundreds of inquiries from the energy codes community every year. Compliance with energy codes is typically a combination of documenting the proposed energy features of the building and passing related inspections. Many jurisdictions require documentation of the proposed design before issuing building permits. Are We Grounded Yet? by John Wiles Heating ventilation and HVAC systems are exposed to the same environmental conditions as PV systems, but there are differences in the grounding requirements and procedures between the two systems.

Who’s Looking Out for Individual Investors? by Jesse Abercrombie I’ve always thought that sometimes the owners of construction businesses are so busy they never really know if their advisors have their best interests at heart. Still, you’d like to know that you’re participating in a system that is fair to everyone and is governed by rules. So you may ask yourself, Who’s looking out for me? Experimental Evaluation of the Corrosion Performance of Copper-Bonded and Galvanized Grounding Electrodes by F. D’Alessandro (B.App.Sc., B.Ed. PhD, SMIEEE) and B. Baumgartner A variety of different electrodes is used for providing effective and safe electrical grounding. The ability of these electrodes to resist corrosion determines their useful service life. Two Buildings – Common Service, Grounding Requirements by Keith Lofland Prior to NEC-2008, two general methods were recognized for grounding electrical systems at additional buildings or structures supplied from a common service.

Editorial: Moving Off First Base by James Carpenter, CEO/Executive Director Yes, we still are divided into sections, chapters, and divisions but that doesn’t mean we should be divided.

Inquisitive Code users wonder why these provisions appear to be different for supply services and for consumer’s services. Australian Perspective: Lift Installations by Darren Margerison Lift installation techniques have changed in recent years with the innovation of a type of elevator commonly known as a Motor Room Less lift (MRL). Other Code: Safety Signs, Part 2 by David Young Safety signs must be more than just legible. According to ANSI® standard Z535, safety signs must effectively get the public’s attention, identify the hazard and the severity of the hazard, inform the public of what actions are necessary to avoid the hazard, and inform the public of the probable consequences of not avoiding the hazard.
