(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. .

(1.5 CEU) Learn what materials are and aren't air barriers. Discover how to locate the air barrier’s air leaks and explore techniques to correct common air-barrier problems.

(7.0 CEUs) Air leakage is among the very most wasteful energy problems found in buildings. This short course defines the  air barrier, discusses how to find air leaks, and describes how to seal ducts and the holes they create through the building envelope.  

(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.

(1.5 CEU) You can learn a lot about a building by studying its energy bills. Learn to separate baseload energy consumption from seasonal energy consumption. Monthly baseload consumption stays nearly constant throughout the year. Seasonal energy consumption varies with the seasons.

(4.0 CEU) Attics are the most important building assembly to insulate correctly. Attic insulation saves energy in both the heating and cooling seasons.

(2.0 CEU) This mini course outlines the most dangerous biological and chemical hazards that we find in buildings and on job sites. We discuss the personal protective equipment (PPE), administrative changes, administrative changes, engineering controls, and hazard elimination to protect workers from respiratory, hearing, vision, and other hazards.

(2.0 CEU)  Most modern, airtight buildings use mechanical ventilation to exhaust polluted air and replace it with fresh air. This mini course explains how ventilation improves human health, building durability, and energy efficiency.

(8.5 CEU) Blower door testing is an important skill for reducing air leakage in buildings. Blower doors provide an initial air-leakage measurement of a building so you can budget the appropriate time and money for air sealing. During and after air sealing, workers can measure their air-sealing success.

(3.0 CEUs) This course will prepare you to take the BPI (Building Performance Institute) Energy Auditor written exam and field exam. Practice the written exam by taking the 50-question exam in this course up to 3 times. You won't take the exact same exam twice because the 50 questions are taken from a 75-question selection. For the field exam, watch the video, study the two reading assignments and take the 12-question test that covers the most important part of the BPI field test for energy auditors.

(3.0 CEUs) This course will prepare you to take the BPI (Building Performance Institute) Energy Auditor written exam and field exam.

(9.0 CEUs) Before we spend money on improving the building's energy efficiency, we do an energy audit. Energy audits require quite a bit of math and other evaluation tools. You need a wide variety of information to evaluate a home and to write a work order. This short course is part of our energy auditor course.

(1.5 CEUs) This test combines energy arithmetic, quantitative reasoning skills, building characteristics, and knowledge of the way we evaluate buildings. The math isn’t difficult, but you need to understand the most important energy equations and be able to use a calculator.

(0.5 CEU, 30 minutes) This course presents a book summary of Building Expertise, Training For Performance Improvement. This book is an important and valuable guide for trainers, based on research by the University of California on training methods that work and don't work. We summarize the book in an 18 minute video and a two page handout.

(8.0 CEU) This building science short course helps you develop a deep understanding of how buildings work. Building science also prevents you from believing energy myths that you’ll hear often from customers, sales reps, and coworkers.

(1.5 CEUs) Building science includes the fundamentals of building physics, energy efficiency, building construction, and building energy retrofit.  Everyone who works in the building trades should understand building science. Building science is one of the main topics of energy auditing and inspecting.

(0.6 CEUs; 40 minutes) This micro course provides an outline of the components and terminology of heating, cooling, and ventilation equipment.

(0.5 CEUs; 30 minutes) When matter changes states from a gas to a liquid to a solid it's embodied heat decreases. If it goes from solid to liquid to gas it's embodied energy increases. This is a very important building science concept. These two videos  give you a comprehensible introduction.

(6.0 CEUs) Many combustion heating systems in existing buildings have problems with fuel-burning and the venting of combustion byproducts. This short course explains the basics of combustion safety testing and combustion venting systems.

(2.5 CEU) Well-designed combustion venting is essential for occupant health, safety, and building durability. This mini course covers how combustion venting systems work and how they can fail.

(0.9 CEUs; 55 minutes) Cool roofs are essential part to reduce electricity use for air conditioning and to keep buildings comfortable during increasingly hot weather. Four videos demonstrate how easy and straightforward it is to take a hot roof and turn it into a cool roof.

(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.

(1.5 CEU) Repairing doors requires quite a bit of good judgement along with carpentry skills. You’ll learn about the most common problems with doors and how to fix them. We discuss the types of door weatherstrip and how to weatherstrip doors.

(5.0 CEU) This short course discusses two ways of evaluating or measuring duct leakage: pressure-pan testing and duct-blower testing. Pressure-pan testing helps to evaluate duct leakage and locate duct leaks. Duct-blower tests quantify air leakage to help energy auditors estimate how much time and effort to spend sealing the ducts.

(2.0 CEU) This mini course discusses industry standards for duct-airtightness and how to interpret duct-blower test results. You’ll learn how to conduct the total duct-leakage test and the leakage-to-outdoors test.

(5.0 CEUs) The main aspects of duct energy efficiency are these: duct air sealing, duct insulation, and airflow through ducts. The purpose of this short course is to help you think about ducts holistically and to understand how ducts relate to heating and cooling efficiency.

(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.
