1 CEU = 1 Hours of Effort

Spray Foam Insulation (Mini Course)

(2.0 CEUs) Spray foam has its advantages its disadvantages. Learn about the most common spray-foam products and installation methods.

Stopping Heat Gain (Mini Course)
(2.0 CEUs) The most effective cooling strategy stops heat before it enters the building. Learn how heat enters buildings and the best strategies to stop heat gain. You’ll learn to limit heat gain in buildings, including: solar heat, air leakage, internal heat gains, and heat transmission.
Temperature and Heat (Mini Course)
(2.0 CEU)  Measure the temperature and the mass of a substance to calculate heat content. Learn about thermometers, latent heat, sensible heat, the greenhouse effect, and how heat is absorbed or released as matter changes its state.
Tips on Teaching by John Krigger (Micro Course)
(0.7 CEU; 45 minutes) How do we optimize the way we teach? Present summaries in your introductions, work from outlines to stay organized, resist distraction, put your ego aside, welcome trainees that may know as much as you do and ask for their help. Expect that learners can answer difficult questions. Use questions to stimulate discussion.
Trainer Communication and Behavior (Micro Course)
(0.8 CEUs; 50 minutes) How do we communicate so that everyone understands us? How do we adopt good trainer behavior and avoid poor trainer behavior? Two videos and some handouts should put you on the right path.
Understanding Summer Heat Gain (Micro Course)
(0.5 CEU; 30 minutes) This 10-minute video breaks down the components of summer heat gain’s including solar gains, air leakage, internal gains, and heat transmission. Understanding how our environment heats our buildings during the summer is essential to creating good summer comfort.
Understanding Thermal Mass (Micro Course)
(0.5 CEU; 25 minutes) Thermal mass benefits some climates and building assemblies but not others. Study some scientific evidence on the value of thermal mass.
Unvented Roof Insulation (Mini Course)
(1.5 CEU) Ventilation air can flow below or above the roof deck, which affects insulation choices. Above-deck ventilation & unvented roofs have advantages over below-deck roof ventilation.
Ventilation Systems Overview (Mini Course)

(2.0 CEUs) Without enough ventilation, buildings decay and occupants suffer respiratory problems. How do we implement a successful ventilation strategy? Find out with this mini course.

Wall Insulation Materials (Mini Course)
(1.5 CEU) In most buildings, walls make up the largest surface area of the building envelope. Study a wide variety of fibrous and foam insulation materials, used for wall insulation, and learn how to select the right wall-insulation material.
Wall Insulation Methods and Materials (Short Course)
(5.0 CEU) In most retrofit jobs, wall insulation presents the challenge of insulating the cavity that you can't see. This course discusses the materials and methods of installing wall insulation to a uniform coverage and density to optimize the R-value and prevent air circulation in the cavity.
Water Heater Basics (Mini Course)
(2.5 CEU) This lesson covers the features of storage water heaters, along with some new water-heater designs. Explore water-heater types, their main components, and compare their efficiencies.
Weatherization Assistant (WA) Software Intro (Mini Course)
(2.0 CEUs) The Weatherization Assistance Program requires energy auditors to use the Weatherization Assistant (WA) software or another software like it.
Whole Building Ventilation (Short Course)
(8.0 CEU) As we make buildings more airtight, we need to install whole building ventilation. Air leakage isn't a reliable means of ventilation. Study indoor-air quality, air leakage, and ventilation strategies. Learn a variety of ventilation systems and discuss how to install them.
Whole Building Ventilation Systems (Mini Course)
(1.5 CEU) Whole-building ventilation systems protect the entire building from excessive moisture and indoor air pollution. This course compares the main types of whole-building ventilation systems.
Window and Door Installation (Mini Course)
(1.5 CEU) Learn about high-performance window and door installation techniques for different window frame types, wall details, and flashing requirements.

Window Economics (Mini Course)
(1.5 CEU) Windows are difficult to measure, choose, buy, and install. This course presents the economic factors of making decisions about windows. We discuss incremental costs and four different ways of measuring cost-effectiveness of window decisions.
Window Introduction (Mini Course)
(1.0 CEU) This course will give you an introduction to the window types and characteristics. Learn about high-performance windows and how to select windows.
Window Performance Factors (Mini Course)
(1.5 CEU) Windows must meet certain performance factors to deliver acceptable comfort and energy efficiency. Learn to select the right windows based on the performance factors described in this course.
Window Performance (Micro Course)
(0.9 CEUs; 55 minutes) This micro course provides a good outline and foundation of window performance and the effects of windows on comfort and energy use.
Window Treatments (Mini Course)
(1.0 CEU) Learn how window treatments insulate windows in winter, block solar heat in summer, which improves building efficiency and occupant comfort.
Windows and Doors (Short Course)
(9.0 CEUs) Understand the characteristics, performance factors, and installation procedures of windows and doors. Windows and doors present complex and challenging decisions for energy efficiency.
Worker Accident Prevention (Mini Course)
(2.5 CEU) This lesson outlines the most prevalent accidents, according to statistics, that workers face on the job. For each potential accident, we outline safe procedures for doing the job while avoiding accidents.
Worker Health and Safety (Short Course)
(8.0 CEU) Workers face a variety of hazards on the job site. In this course, we focus on the most statistically dangerous of these hazards, including falls, back injuries, repetitive motion, extreme weather, driving, tools, noise and confined spaces.
Worst-Case Depressurization Testing (Micro Course)
(0.9 CEU; 55 minutes) Naturally drafting combustion appliances often spill their combustion products and produce carbon monoxide. Worst-case depressurization testing is an accepted way to discover whether a particular heating appliance is spilling or producing CO during worst-case conditions.
