(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.  

(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.

(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.

(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.

(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.

(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.
