Residential energy use today accounts for about 20% of U.S. greenhouse gas emissions – though this figure varies widely by region and income level. Certainly, getting more of our energy from renewable resources can help reduce those emissions, but we also need to limit overall energy demand in order to meet the emissions cuts necessary to blunt climate change’s worst effects.

I was talking to my brother, Mark, on the phone last night. We’d been trying to connect all week and finally got the chance. I’m in Arkansas and he’s in Arizona, so the time difference can be a pain.

We just missed each other the day before because he was over with the neighbors across the street.

There have been many times when I was elbows deep in a wiring trough or raceway. We sometimes called the smaller units gutters, but all were raceways and wiring troughs.

Looking through a manufacturer’s online enclosure catalog recently, I came across a term I hadn’t heard before. Now, I’m not a contractor, so I likely haven’t seen as many of these listings as you might have. But I am a journalist who has covered the construction industry for several decades, and the term “mild steel” stuck out to me when it showed up as a material option for the maker’s broad range of enclosure offerings.

In new construction, sustainable building practices are becoming the norm. But even in existing buildings, simple strategies can be implemented quickly and easily to address inefficiencies, reduce energy use, improve comfort, and enhance productivity in the space.

Some facilities are changing their requirements for motor and appliance installations. This could be due to OSHA Lock-out and Tag-out requirements or NFPA 70E. The change is toward using pin and sleeve devices instead of having a hard-wired installation.

Safety requirements often have the maintenance person checking for the absence of voltage before touching. The rules are quite specific and are enforced by OSHA.
