Lesson: Cooling Principles
This Cooling Principles lesson covers the sources of heat gain in buildings and how your climate affects cooling loads. The lesson explains common energy-efficiency strategies that minimize cooling costs by reducing heat gains. Air conditioning is expensive and should be our last resort for cooling a building. This lesson covers the following topics: how people and buildings get rid of excess heat, how to stop heat before it gets into buildings and cost-effective methods for removing excess heat. This is a 1.1 hour session.

Lesson: Electric Power and Energy
This Electric Power and Energy lesson you’ll learn how electricity works, how it’s measured, and how we use it we use it in buildings. Building-energy specialists must understand electric power and energy, however many don’t. This lesson covers the fundamentals of electricity generation, transmission, and consumption. This is a 1.2 hour session.

Lesson: Energy Calculations
This Energy Calculations lesson covers the most important notations, conversions, and equations you need to know as a building energy inspector or design consultant. This lesson also contains calculation exercises that give you practice at solving simple energy problems. Energy calculations help you and your customers decide on energy-efficiency improvements that make sense for your project. This lesson covers the following topics: energy-unit conversions, heat-transmission rates, air-change rates and energy-improvement payback periods. This is a 2.0 hour session.

Lesson: Geometry
This Geometry lesson covers the basic geometric building shapes you’ll measure and calculate. You’ll learn how to calculate building areas, building volumes, and do other useful geometric calculations. Building-energy specialists and design consultants frequently use geometric calculations for energy auditing and building design.   This is a 1.6 hour session.

Lesson: Heat Loss and Gain
This Heat Loss and Gain lesson will show three modes of heat transmission and how heat transmission occurs in building assemblies. We divide heat transmission into two major compliments: heat loss and heat gain. Heat loss and heat gain determines how much energy a building uses for space conditioning. This lesson also covers how to minimize heat transmission in buildings. This lesson covers the following topics: primary drivers of heat transmission in buildings, methods to evaluate heat loss and heat gain in buildings and the best strategies to improve buildings with excessive heat-transmission. This is a 2.0 hour session.

Lesson: Heating and Cooling Introduction
This Heating and Cooling Introduction lesson covers how the thermal envelope, HVAC systems and occupant behaviors affect the heating and cooling needs of buildings. One essential purpose of a building is to provide comfort. Buildings that don’t provide adequate comfort cause occupant dissatisfaction and reduced occupant productivity. This lesson covers the following topics: seasonal space-conditioning loads, how the building envelope affects heating-and-cooling loads and cost-effective HVAC-efficiency strategies. This is a 0.7 hour session.

Lesson: Air Barrier Basics
Air barriers are an essential part of the building envelope, but leaky or incomplete air barriers are ineffective and may even create safety hazards. This lesson covers air-barrier principles and typical air-barrier installation problems. You’ll learn how to locate common air-leakage sites and techniques to correct common air-barrier problems. This is a 1.3 hour session.
BPI (0.65 CEUs)

Lesson: Math Operations
This Math Operations lesson teaches student how to interpret math symbols and how to use math operations to solve common building-energy problems. Math skills are essential to understand building science. This lesson covers the following topics: building energy / math operations, taking measurements, areas and volumes, performing conversions and solving equations. This is a 1.4 hour session.
BPI (0.70 CEUs)

Lesson: Temperature and Heat
This Temperature and Heat lesson covers how temperature and heat flow affect building energy-performance and comfort. Temperature and heat are some of the most important and misunderstood principles of building science. This lesson covers the following topics: the relationship between temperature and heat, the three primary modes of heat flow and the difference between sensible and latent heat. This is a 1.9 hour session.
