In 1977, the Missouri Department of Natural Resources responded to the energy crisis of the early 1970s, establishing the Low-Income Weatherization Assistance Program (LIWAP) in the Division of Energy. The program provides cost-effective energy-efficient home improvements to Missouri's low income households, especially the elderly, children, those with physical disadvantages, and others most affected by high utility costs. The program’s objectives are to lower utility bills and improve comfort while ensuring health and safety. LIWAP takes a whole-house approach to energy efficiency. The cost-effectiveness of energy efficiency measures is considered using modeling calculations derived from home energy audits conducted by weatherization professionals. Weatherization is the nation's largest residential energy efficiency program.

Rationale for Providing LIWAP Services
Home heating and cooling are high-cost basic necessities. Americans spent more than $230 billion in 2010 on residential energy according to a 2010 Oak Ridge National Laboratory study. Low income households carry a larger burden for energy costs, typically spending 16.3% of their total annual income on utilities. On average, other households spend only 3.5% of their annual income onenergy costs.  Low income families often must cut back on other necessities such as healthcare, medicine, groceries, and childcare to pay their energy bills. Other low income people live in older homes that may not have insulation or may have older, less efficient appliances. LIWAP is a long-lasting solution to these problems.

Households that have received weatherization services are better able to pay utility bills and reduce debt.  A home that has been weatherized can reduce average annual fuel usage per dwelling by 30% for the typical low income home. Weatherization allows for a reduced burden on utility assistance providers, and the energy savings achieved through weatherization allow for the program to be cost effective.

Program Accomplishments

The program uses an energy audit procedure to establish cost-effective weatherization measures. The audit is used to calculate reductions in energy usage and takes into account factors such as changes in the thermal and heat transfer characteristics of a dwelling, appropriate weather data, and economic factors such as fuel and installation costs. Energy auditors gather information and perform diagnostic tests on each home, including blower door tests and infrared thermograghy. These tests help detect and locate air leaks and other weaknesses in the building envelope, providing opportunities to perform more cost-effective work. Heating systems are also tested for efficiency and safety, and repairs are made accordingly. Energy efficient measures may include, reducing air infiltration, increasing insulation in walls, attics, floors and foundations, HVAC repair or replacement, LED lighting replacement, refrigerator replacement, water heater blankets.

Program Operation

Annual allocations to these agencies are based on the percentage of the state’s total low-income households within each weatherization agency’s service area. The agencies provide weatherization services, training and guidance to eligible applicants. The program saves applicants money and stimulates the state and local economy. The agencies use their own crews or contract the work to area businesses. Most materials and products used in the weatherization process are purchased from state and regional manufacturers. Indirectly, through an economic multiplier effect, weatherization funds are used and reused, stimulating the state’s businesses and creating jobs.

To apply for assistance, applicants should contact their local weatherization agency. The agency will ask the homeowners to complete the appropriate forms, which include income documentation to verify eligibility. Once the applicant is verified as eligible, an auditor from the agency will conduct a pre-inspection of the home to determine what steps will produce the greatest energy savings. The next step is for the agency crew of contractor to apply the energy-efficient improvements to the home. After the weatherization of the home is complete, a quality control inspector will examine the home for quality of work and completeness. The Division of Energy monitors the work of the agencies to ensure state and federal guidelines are followed.
