Why is it that almost everyone thinks green building is too expensive? Well, they're wrong. A recent survey found that most people overestimated the cost of green building by 300%. No wonder they thought it was out of their price range. The truth is that opting for environmentally conscious building materials and practices adds just 5% to the construction costs. That hardly breaks the bank. The problem is that misconceptions persist and end up limiting the number of people who build or buy green. The answer is some positive PR. Let's all focus on making more green building selections and sharing the news with our neighbors. After all, that's how change happens.
