Weatherization - University of the District of Columbia

    Sample of state weatherization requirements.


    The following weatherization standards are code requirements:

    ? WINDOWS must be double-glazed or equipped with storm windows. Exempted are windows in

    doors and furnace rooms. Windows located in basements, which are not habitable rooms may be

    permanently sealed and insulated to R-5 in lieu of double-glazing or installing storm windows.

    ? PATIO DOORS AND INWARD-SWINGING EXTERIOR DOORS must be insulated and double-glazed; or

    be equipped with a storm door, unless they are provided with a vestibule. Storm doors must have

    self-closing devices.

    ? WEATHERSTRIPPING must be installed on exterior doors and windows where operable parts meet.

    ? CAULKING must be applied to exterior joints, including around doors and windows for the first three

    stories of the building, as well as around the sill plate and utility penetrations.

    The Department will accept blower door testing of the building, per Comm 67.05(4), in lieu of the

    prescriptive infiltration measures.

    ? MOISTURE CONTROL - Ventilation must be installed in attics and crawl spaces at a rate of 1 sq. ft. of

    free area of ventilation per 300 sq. ft. of floor area. A vapor barrier must cover the ground in crawl


    ? INSULATION must be installed in "accessible" areas to the levels shown in Tables 67.05-A through C

    of the Code (see the following condensed table). "Accessible" means the space can be reached

    without removal or alteration of any finish materials of the permanent structure. For example,

    enclosed wall cavities are considered inaccessible and do not require insulation. However, an

    unfinished attic with floorboards must be insulated under the boards, if not insulated on top.

    NEAT, a Department of Energy--approved residential energy audit tool. The NEAT classroom students

    learn the use of the computerized auditing tool that helps simplify the identification of measures that

    should be completed on the homes in the field. Savings-to-Investment Ratios (SIR) are calculated by the

    computer program to identify cost effective measures.



    This two-day class addresses maintenance and repair procedures unique to oil-fired heating units.

    Participants will learn how to perform proper combustion testing techniques and how to evaluate these

    tests to achieve clean energy efficient operation. Lab time will include disassembly of a burner, cleaning

    and adjusting, re-assembly and firing. Classroom discussions will cover the requirements of state and

    national codes.

    PREREQUISITES: HUI AND HHSE RESIDENTIAL VENTILATION (VENT): In this 2-day class, students will learn how to determine ventilation strategies for homes based on the

    number of permanent residents, their living style, and other issues within the house. Crawlspace and

    whole house ventilation techniques will also be explored.


    SHORT FORM MANUAL J (MANJ): This class is designed to instruct heating technicians in the proper sizing of residential heating units

    installed in the weatherization program using modified manual J revision 7 calculations. Sizing is

    Wisconsin Weatherization Training RFP (excerpts)

    Weatherization work is done in a team setting, usually involving an energy auditor to assess the work

    that needs to be done, an installation crew with supervisor that does much of the hands-on work to

    upgrade the home’s efficiency, and sometimes HVAC or insulation subcontractors. While the emphasis

    is on energy-efficiency, projects also take into account occupant safety and comfort.

    Workers usually enter the field as installers with some experience in residential construction, but need

    to learn weatherization diagnostic skills and energy-efficient building practices on the job. From there,

    they can progress to a variety of positions. A common career path involves progression to crew

    supervisor or energy auditor. Other relevant careers to which installers progress range from inventory

    management, quality control inspector, independent contractor, as well as weatherization program


    Weatherization is closely related to the building performance industry, which seeks to improve the

    performance of homes occupied by households with incomes above the low-income threshold, as well

    as commercial buildings. Weatherization workers are in a good position to move into jobs in that

    industry, as well as residential construction.

    The Weatherization Program foresees a need for a greater-than-normal influx of weatherization workers

    to accommodate upcoming retirements and program growth. This programmatic need, combined with

    a state policy objective to provide more opportunities for underemployed young adults in the

    Milwaukee area, led to the development of a pilot on-the-job training initiative.

    The goals of this pilot initiative are to:

    ? develop weatherization installers to be productive members of Milwaukee area weatherization


    ? bring crew members into the field who have the potential to grow within the field to such

    positions as energy auditors;

    ? test the viability of an on-the-job training program for possible statewide implementation; and

    ? provide employment training and opportunities for underemployed people in the Milwaukee

    area to fill current and future jobs in the expanding green job fields of residential energy

    conservation and building home performance.

Boot Camp Training -- Upon completion of the “job ready” phase of the initiative, WECC will hold a five-

    day weatherization boot camp training for the trainees. In this training, the participants will learn the

    basics of weatherization theory and proper installation technique. An outline of the boot camp contents

    is attached to this RFP as Attachment A.

    On-the-Job Training After the boot camp, trainees will transition to local weatherization crews for 12

    months of on-the-job training, which will include placement on a weatherization crew, some classroom

    training, and continued support by the contractor(s). The purpose of this phase of the initiative is to

    ensure trainees meet the Core Competencies for the Weatherization Assistance Program (available at

    April 20, 2009 Page | 8

    Most of the trainees’ time will be spent as productive members of weatherization crews. For this work, each trainee will be assigned to an existing weatherization crew and provided a mentor who will provide in-the-field instruction on weatherization practices. We expect that the contractor(s) will provide support to the weatherization agencies or their subcontractors in making placement assignments and providing assistance to the mentors, as they are likely to be technically skilled in weatherization but may have little prior experience in mentoring. This support will include a formal orientation for on-the-job mentors in their role and any help needed with the interaction between the mentor and the contractor. In addition, we expect that about 10 percent of the trainees’ time will be spent on classroom training. We have identified several appropriate training opportunities that will be available through the statewide weatherization program, but expect the contractor(s), with the assistance of the local weatherization agencies, to identify and arrange additional training that should be arranged through other providers. One likely training offering would be computer training available through the technical college system. The professional weatherization training we envision includes:

    ? intermediate weatherization installer training (5 days)

    ? construction related software training (5-8 days)

    ? basic building systems training (5-8 days)

    ? advanced weatherization installer training (4-6 days)

    ? basic energy auditor training (5 days)

    The professional weatherization training will be provided under the auspices of the State’s current weatherization training contractor, WECC, and will be covered via the weatherization agencies’


    We anticipate that the contractor(s) will arrange regular check-ins with the trainees, the mentors, and the local weatherization agencies to ensure progress and overcome any problems that arise. The

    contractor(s) will continue to offer any appropriate services to the trainees to help them be productive members of their assigned teams and progress toward graduation. We are looking for bidders to

    identify appropriate approaches and timing for these check-ins, any evaluation processes that may be needed, and what services they are prepared to continue to provide, if needed.



    The following is for information only. This training will be sponsored by the State of Wisconsin, under the Weatherization Assistance contract. It is part of the planned program but not part of the RFP requirements.
