I have really mixed feelings about all this "green" stuff. Some aspects of "green" living seem to be very legitimate, and other angles seem, well frankly, bogus. But whether I like it or not, I think it is here to stay with us, so we need to sort out what is true and what is hype. In the latest copy of the NAHB green building standard, on page 73,
section 902.10, you will find that builders, hoping to accumulate green
points, get 5 points for a central vacuum system exhausted outside.
There are a couple of interesting things to consider...first you only
get the points if you vent that system outside.
Having been in this industry for several decades, I firmly believe that
unless it is impossible, every central vacuum system should be vented
outside. This is the only way to guarantee that you are not venting
dust back into your home. If you have ever had a central vacuum system
or been around a home with a central system that was not vented
outside, you know that after a couple of years the system begins to
smell like dust,your animals, or dirt. When you vent outside this
simply does not happen. We used to have a system in our home that was not vented outside. We also had an Irish Setter, who was sweet, but smelly. When you would turn on our un-vented central vacuum system our entire garage would smell like Rusty. After Rusty went on to the squirrel hunting ground in the sky, he was never far from us...all we had to do was turn on the vacuum and we could smell him. So if I were judging, I would say a central vacuum system vented to the outside really will improve the indoor air quality of a home.
Secondly, if you get your hands on a copy of
the entire green building standard it is obvious that a central vacuum
system might be one of the very easiest, and least costly ways to
accumulate five points. If you are considering a green building
project, a central vacuum system is really an important component.
Understanding that living green is extremely important to many of our customers, we created a "Living Green" page to help them determine which products on our website are the best green choices. Take a look if you are interested.
