What is humidity? According to Wikipedia, humidity is the amount of water vapor in the air. A nice, simple explanation that all of us can understand. Now look at the chart below. Continue reading “Building Science-Humidity”
Building Science-“Breathe”
In this blog, I’m going to discuss building tightness and the code dealing with air leakage. The 2012 International Residential Code for One and Two-Family Dwellings is the current code in force for the state of Minnesota at the time of this blog. Chapter 11 deals with energy conservation, what most in the building industry call the energy code. The code on building air leakage states: Continue reading “Building Science-“Breathe””
Building Science-Thermodynamics
Building science 101 is going to be a continuing discussion about building science and how it relates to building in a cold climate. We must start at the beginning, which unfortunately has to do with physics. A nasty word, but I’ll try my best keep things simple. The basics of building science mostly deal with the laws of thermodynamics. Continue reading “Building Science-Thermodynamics”
