Six elements in a green home

In order to avoid a greenwashed home, here are some things to look for to identify a truly green home:

?Site planning for the house that is sensitive to the immediate environment, minimizes tree destruction and is strong on managing water runoff.

?Energy efficiency throughout, including high-performance HVAC, lighting, insulation and appliances.

?Exceptional interior air quality through the use of advanced air filtration and exchange systems.

?Extensive use of nontoxic building materials.

?Water conservation efficiencies, such as water-saving toilets and shower fixtures and possibly some reuse of waste water.

?Ease of long-term operation and management.

I would guess most buyers would first think of #2 on the list: efficient lightbulbs, a newer furnace, AC unit, and appliances, good insulation and no obvious drafts or leaks. But, some of these other things are much harder to find, particularly it is an older home. Nontoxic building materials? How many homes – even new ones – have this? And air quality – isn’t this something that is used in the rare passive home? And #6 is interesting: the green features should be relatively to utilize and maintain.

This leads me to several questions:

  1. How many green homes would meet all six of these?
  2. What is the added cost of meeting all 6?
  3. Presumably, some of these six are more important than others. Which ones make for a greener home if you could only have/afford a few?

Expect to see more listings in coming years that emphasize green features.
