Course Overview (22 min) Indoor Environmental Quality refers to the elements that create a comfortable setting for the inhabitants of a building, what keeps us from being "too hot or too cold". Here Deane Evans introduces the concept of integration - the optimization of the building envelope and HVAC systems in a commercial building to control the indoor environmental quality.

Thermal Comfort (25 min) Thermal comfort is a key factor that contributes to the overall comfort of occupants in a commercial building. In this session, Deane Evans explores a range of variables that commercial building designers focus on to create and maintain a comfortable indoor environment.

Properties of Moist Air (23 min) Moist air serves as the heating and cooling medium of an occupied space, and therefore is a critical element in establishing thermal comfort. In this lesson, Deane Evans examines the properties and measurement of moist air that allow building designers to control and condition indoor air.

Thermal Resistance (21 min) Understanding thermal resistance is key to understanding how the air moving through a building envelope contributes to indoor environmental quality. Here Erv Bales examines the impact of a wall system's R-value on moisture and heat flow in a commercial building.

Thermal Loads (23 min) In this lesson, Erv Bales provides a background for understanding how system designers quantify thermal and air infiltration loads inside the building to better understand how Commercial building environmental levels are maintained.

HVAC Basics (26 min) Summarizing the principles introduced in this course, Deane Evans explains how they relate to the basic types of HVAC that are used to manage the thermal loads in commercial buildings while describing the many complex Commercial building HVAC types.
