It takes a team to solve energy efficiency problems. And the team members must be focused on energy efficiency so they have the products, knowledge, experience and interest to offer energy efficient products and services. Most tradespeople working today were trained to install products in the most cost effective way without consideration for long-term operating costs. But energy efficiency is all about long-term operating costs. So, if you and your tradesperson are just focused on his bill, you'll miss the big picture. The cheapest approach today may be the most costly in the long run.
