Yet the amount of air that can transfer in and out of our homes from drafts around windows, doors, pipe outlets, cracks in the foundation, clothes dryer vents, attached garage doors, even electric switch and plug outlets, can add up to the equivalent. In the winter, these drafts make our heating system work harder. The same is true for the air conditioner in the summer. The result: a waste of energy, more carbon and higher energy bills. By using the best draft-dodging practices
to seal or block these leaks, we can increase energy efficiency and reduce energy consumption, along with its accompanying greenhouse gas emissions, which are so harmful
to the environment.
