Mobile-Home Air Sealing and Duct Sealing (Mini Course)
(1.5 CEU) Find mobile-home air leaks  in predictable locations. Blower door testing helps workers to evaluate the existing air leakage and to plan the air-sealing work. Air sealing mobile homes is no more difficult than air sealing site-built homes and is often easier.
$25.00
Mobile-Home Construction (Mini Course)
(2.0 CEU) Workers assemble the home in the factory, starting from the steel trailer up through the roof. The construction sequence and methodology is quite different from the methodology of building a site-built home.
$40.00
Mobile-Home Floor Insulation (Mini Course)
(1.5 CEU) Insulators blow fiberglass insulation into the floor cavities, using a variety of methods. In this course, you’ll learn  how to insulate floors by drilling through the rim joist. and through openings underneath the floor.  
$35.00
Mobile-Home Roof Insulation (Mini Course)

(1.5 CEUs) Mobile homes have minimal amounts of roof insulation. There is usually room in the roof cavity to roughly double the insulation R-value.

$35.00
Mobile-Home Shading (Mini Course)
(1.5 CEU) Older mobile homes lack overhangs to shade windows and newer homes may have an overhang that provides little shade. The roof colors of mobile homes are often a dull grey or a dark color of shingles. These characteristics lead to excessive summer solar gain. This course discusses shading structures, solar screens, window films, blinds, and cool roofs.
$35.00
Mobile-Home Wall Insulation (Mini Course)
(1.5 CEU) Many weatherization agencies and private contractors insulate mobile home walls successfully. This course demonstrates two ways to insulate mobile home walls: stuffing batts into the walls using a batt stuffer, and blowing fiberglass wool into the walls, using a fill tube.
$35.00
Mobile-Home Weatherization (Short Course)
(9.0 CEUs) Mobile and manufactured homes are different in many ways from site-built homes. Insulation levels in the roof, walls, and floors are minimal. You will learn of variety of air-sealing, insulation, and repair methods in this 6-lesson course.
$225.00
Mobile-Home Weatherization (Test)
(1.5 CEUs) Test content: mobile-home construction, testing, diagnosis, air sealing, duct sealing, along with roof, wall, and floor insulation.
$75.00
Moisture Management (Mini Course)
(1.5 CEU) Moisture is most potent destructive force affecting buildings. Moisture affects human health and building durability. Learn how moisture moves through buildings in complex ways and how to control moisture.
$2,535.00
Moisture Management for Buildings (Short Course)

(8.0 CEUs) Moisture is most destructive force affecting buildings. Learn how to stop moisture from affecting human health and building durability.

$200.00
Moisture Theory (Mini Course)

(2.0 CEUs) Some airborne moisture prevents dryness in the mouth and sinuses. Too much airborne moisture causes building damage from condensation.

$50.00
Multipoint Blower Door Tests (Micro Course)
(0.6 CEU; 40 minutes) Multipoint blower door tests are useful for harvesting a variety of diagnostic data that single-point test can't provide. This micro course presents two videos and several reading assignments on multipoint blower door testing with and without software.
$10.00
Non-Invasive Superheat Testing (Micro Course)
(30 minutes) The noninvasive superheat test lets you estimate the superheat of an air conditioner or a heat pump operating in the summer. Noninvasive means that we don't have to connect of refrigeration manifold and performing this test doesn't require a refrigeration license.

Photovoltaic Systems Field Guide

by John Krigger

The Saturn Field Guide to Photovoltaic Systems provides a general introduction to the photovoltaic technology used on today's residential and light commercial buildings.
$15.00
Pressure Pan Testing (Mini Course)
(1.5 CEU) The pressure pan measures duct pressures during a blower door test. If you measure pressure with a pressure pan at a duct register during a blower door test, that indicates that outdoor air is leaking into or out of the ducts. Pressure-pan testing isn’t a quantitative measurement of duct leakage, but it does help you find duct leaks and to evaluate the relative amount of duct leakage.
$40.00
Professional Insulation Equipment (Mini Course)
(1.5 CEU) This Professional Insulation Equipment lesson presents the vehicles, machines, tools, and protective equipment used for installing insulation.
$35.00
Professional Sprayed and Injected Foam (Micro Course)
(0.8 CEU; 50 minutes) Professional installers spray foam on surfaces and inject foam into cavities. Sprayed and injected foam are excellent choices for some applications. Learn from a few examples. Spray foam is by far the most common installation. And you can observe the coverage of spray foam. Injected foam is more of an unknown because installers inject it into closed cavities. Both types of liquid foam require a precise mixture and a narrow temperature range. Shrinkage, voids, and cracking can be a problem. Although sprayed and injected foam in this course is low-density polyurethane foam, except for the final video, which features high-pressure high-density polyurethane foam.
$20.00
Quality Control Inspector (Test)
(3.0 CEUs) This test focuses on the knowledge and experience of an energy auditor who’s been on the job more than five years. Many of the questions on this test require on-the-job experience to answer correctly. Tests you on the knowledge, training, and experience of an energy auditor.
