Weatherization comprises a comprehensive series of energy efficiency measures that are based on sophisticated analyses of individual homes. These analyses take the whole-house approach, which maximizes energy and dollar savings.

Weatherization as defined by the Weatherization Assistance Program (WAP) differs in many ways from what is commonly called “weatherizing your home.” The latter involves low-cost improvements like adding weather stripping to doors and windows to save energy.


Another distinguishing feature of weatherization is attention to an all-around safety check. Many buildings receiving attention are old and in need of repair. Weatherization service providers check energy systems to ensure occupant safety.


Weatherization service providers look at the house as a system under the concept of "whole-house weatherization."

WestCOP’s weatherization services consist of cost-effective energy efficiency measures for existing residential and multifamily housing with low-income residents. It includes a wide variety of energy efficiency measures that encompass the building envelope, its heating and cooling systems, its electrical system, and electricity consuming appliances.

The benefits of weatherization begin with reducing the energy bills of recipients for a long period of time. Some measures, such as insulating walls or roofs, for example, can provide savings for the lifetime of a house—30 years or more. On average, the value of the weatherization improvements is 2.2 times greater than the cost.

WestCOP’s Weatherization program serves low-income families free of charge and limits the amount of money that can be spent on any single residence as determined by federal rules.
