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.
  • Cost-effective methods for removing excess heat.

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 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
  • Energy-improvement payback periods.

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 lesson is approved for .80 BPI CEUs.

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.
  • The best strategies to improve buildings with excessive heat-transmission.

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.
  • Cost-effective HVAC-efficiency strategies.

This lesson is approved for .35 BPI CEUs.

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
  • Solving equations

This lesson is approved for .70 BPI CEUs.

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.
  • The difference between sensible and latent heat.
