(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.

(0.7 CEU; 35 minutes) This 10 minute video explains how to use manometers during blower door tests to find clues about the performance of air barriers. We call the tests contained in this video: simple pressure diagnostics.

(0.3 CEU; 20 minutes) The video in this micro course provides you with a mental map of home-energy usage. The reading informs you about the relative amount of energy that the energy consumers use. Together, the two should help you realize the different opportunities saving energy and the approximate value of each opportunity.

(0.5 CEU; 30 minutes) This micro course contains a variety of information on the most common electric circuits found in buildings. We present electric circuits in two videos. The questions in the exam are based on the two videos. We also include two optional readings for some auxiliary information about electricity use in buildings.

(0.6 CEU; 40 minutes) The HVAC refrigeration cycle is a very important concept in building science and HVAC. This micro course is a good introduction or a good refresher course, in case you haven't thought about refrigeration in a while. Most of the content in this course is in the videos, but don't neglect your reading assignment under the Materials tab.

(0.9 CEU; 55 minutes) Airflow and static pressure directly relate to HVAC efficiency and to each other. Measuring static pressure is considerably easier than measuring airflow. This micro course gives you the fundamentals of how to measure static pressure and to make decisions based on your measurements.

(0.5 CEU; 25 minutes) The video explains the process of evaluating and servicing a typical residential HVAC system. The focus is on troubleshooting and logical progression of tasks. Handout outlines procedures. .

(0.7 CEU; 45 minutes) Building pressures cause air infiltration and exfiltration. Unbalanced airflow between supply and return ducts causes positive pressures in some rooms and negative pressures in others. Duct air leakage in intermediate zones makes the building either positively or negatively pressurized. This micro course explains these effects and how to solve the problems they create.

(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.

(0.2 CEU; 20 minutes) This 14-minute video explains how scientists measure the thermal resistance of insulation, using a guarded hotbox.

(0.7 CEU; 45 minutes) Dense-pack wall insulation is one of the most effective energy-saving retrofits available to insulators and their clients. This micro course shows you the main tools and methods with three videos and an illustrated handout.

(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.

(0.3 CEU; 15 minutes) A factory-trained expert shows you how to install one-part and two-part foam as insulation and air sealing on new or existing buildings.
