Introduction to Weatherization TG module

Features

Objectives:

1.         Explain the purpose, benefits, and origin of the weatherization program.

2.         Explain how weatherization goals are achieved by reducing thermal losses and air infiltration in residences.

3.         Describe the methods used to locate sources of thermal loss and air infiltration.

4.         Describe the methods and materials used to reduce thermal losses and air infiltration.

5.         Describe the energy impacts of various components of the building shell.

This module introduces the reader to the weatherization initiative and its underlying motivation by examining the economic and environmental effects of the inefficient use of energy in heating and cooling buildings. It describes the common ways in which heat is lost and how cold air infiltrates a house.  It also introduces remediation methods such as air sealing and insulation as a lead-in to subsequent modules. The module also explores career opportunities in the weatherization industry.
