The Many Shades of One Color: Part 1

Green is almost undeniably one of the most marketed colors as it relates to the environment, sustainability, and energy. But what exactly does “green” mean in relation to environmental and energy issues?



More importantly, can a modern product or process really be considered green, and if so, by what benchmark? For example, we know that CFLs use less energy than incandescent lights, but does consuming less energy really make a product greener?

A few months ago I had lunch with a friend of mine who recently bought

an older historic home in southern Ohio. The subject of insulation and

heating costs came up and we engaged in a bit of a debate over what kind

of insulation to use. Now, I don’t believe either of us won, primarily

In Winter, Those Who Are Proactive Profit The Most



I hate to be the bearer of bad news, but in the next few weeks, old man winter will make his annual appearance once again. Unfortunately (or fortunately, if you like winter), with his arrival, snow and cold winds are close to follow.



To prepare for the oncoming winter months, use this time in late fall to find weak areas in your homes thermal shell. (For the sake of clarification, I define “Thermal Shell” as the…
