It’s important to know why we’re putting so much pressure on you to learn about pressure.

To put it simply, it’s how we are able to measure the leakage of a building or a duct system. We know if we can limit the unwanted leakage of a building or duct system, the building stands a much greater chance of being comfortable and efficient. Of course, there are more components to consider when talking about comfort (humidity, insulation, etc…), but you’ll be hard-pressed to make a building comfortable without addressing these two pieces first.

In this first lesson, we’ll break down how pressure is the key variable that helps us measure leakage and diagnose many comfort problems.
