There is a running joke in our business that electrical engineers don’t know anything about energy efficiency. It is only a joke. One of the sharpest energy guys I have interviewed was a physics major who started on the ground floor of an energy efficiency consulting firm filling orders of equipment they also happened to sell. In 10 years he worked his way up to really understanding how buildings and their complex systems work and he became a manager of a team of energy engineers teaching his group how buildings work and how to model them.

This week – a little diversion into engineering. Go ahead. Shake those goose bumps out. There are three universal laws of thermodynamics but I’m not going to explain them all now or you might fall asleep and hit your head on the table. I will only cover one of them. A law is essentially a theory of something that has never been disproven. One of these laws indicates the direction of all processes. Heat travels from hot to cold. Water runs downhill. However, heat can travel from cold to hot and water can go up hill if you add energy. …
