The National Association has just released some statistics about how green home features are affecting buyers decisions when purchasing a home. While commuting costs are a big concern for younger buyers, energy heating and cooling costs are the number one concern as buyers get older. Even though the data paints a broad stroke over the entire nation, it is safe to say that commuting and energy costs rank high in Minnesota, too. Local builders are taking building “green” into account, some becoming GreenStar certified.
