Building Science Courses
Introduction to Psychrometrics
Goal: Understand the relationship between dry air & water and explain its impact on indoor air quality.
Lesson 1: Air, Water, Energy
Objective – Describe what is in air, how the air molecules relate, and how water vapor fits in to the mix.
Lesson 2: Moist Air Properties
Objective – Describe various properties related to the mixture of dry air and water vapor molecules. The properties we will cover include dry bulb temperature, web bulb temperature, relative humidity, humidity ratio, and dew point.
Using the Psychrometrics Chart
Goal: Calculate the common properties of moist air using the psychrometric chart. Another goal is to use these calculated properties to help identify potential indoor air quality problems.
Lesson 1: Chart Basics
Objective – Describe the x and y axes of the psychrometric chart, understand movement around the chart, and explain the concepts of sensible heat, latent heat, and enthalpy.
Lesson 2: Getting Oriented
Objective – Identify the 7 different lines on the psychrometric chart.
Lesson 3: Calculations
Objective – Plot the given conditions on the psychrometric chart, calculate other properties, and graphically display air mixing and process changes.
Managing Moisture I
Goal: Identify where and why liquid water can enter a building and solve problems related to water intrusion.
Lesson 1: From Above
Objective – Describe common roof types and identify the areas where they are most vulnerable to water intrusion.
Lesson 2: From Below
Objective – Understand moisture problems that happen at the foundation of a building.
Lesson 3: From the Side
Objective – Identify the components of common walls and describe how they should properly drain.
Managing Moisture II
Goal: Understand how water vapor can enter indoors via diffusion & infiltration and cause indoor air quality problems.
Lesson 1: Vapor Diffusion
Objective – Explain how vapor pressure differentials can drive moisture through materials via diffusion. Also, be able to describe how materials can be measured for permeability and know where they should be placed in different climates.
Lesson 2: Air Infiltration
Objective – Describe how leakage paths and pressure differences cause air infiltration, which can lead to indoor air quality problems.
