Building Science is not really science; it is more of a concept. While the concepts were developed by scientists the system itself is not really hard science. The concepts are generally employed by building analysts and construction professionals. While I consider myself a student of building science I do not consider myself a building scientist. I am simply a tradesman with special training. While some in the field might have different opinions about their role in this industry I am comfortable with my statement above.

Building science is easy and yet complex to explain, most of the concepts are simple scientific principles. We take the basic principle such as the laws of thermal dynamic and apply them and how they work within a building. We can easily determine that heat moves from hot to cold and that we want a barrier between our home and the outside. Not exactly hard to conclude.

Where we differentiate ourselves is through testing. We figure out through our blower door test how much is leaking and attempt discover where. As we seal the home we continue to test. We use our training and experience to try to determine if these changes will effect others systems within the house.

You will often here that we look at the house a system. We want this system working for you and not against you. How is the stack effect complicating the efficiency of your air conditioner? Why the house is going into negative pressure when the heater is turned on? Why does your bath fan not work? How can we get these systems working in concert, to provide safety, comfort and energy efficiency?

While some really smart people figured these concepts out. They tinkered, they theorized, they failed and they succeeded. They used this data and shared it and came up with a process to convey this complex information and boil it down into a simple system that could be taught.

I am one those that has studied these principles and has been taught the system. You never look at the house in the same way after this training.
