1.0102 Pre-Implementation Inspection

When you receive the weatherization file review the approved estimation form and other related documents:

At the job site greet the owner/tenant, identify yourself, state your purpose, and review the job schedule.

Walk around the exterior of the home:

Walk through the interior of the home:

Complete initial diagnostics:

Review proposed work with the client:

1.0103 Quality Control Inspections

As per U.S. Department of Energy Weatherization Program Notice 15-4 - Every Unit reported as a "completed unit" must receive a final Quality Control Inspection ensuring that all work meets the minimum specifications 1.0101 outlined in the Standard Work Specification (SWS) in accordance with 10 CFR 440. Quality control inspections ensure that weatherization services have been provided in a quality manner and that the home is left in a safe condition.

All Quality Control Inspections will include, but not be limited to:

1.02 Energy Audit

Completing an accurate Energy Audit requires appropriate analysis of the on-site inspection information based on the following NeWAP requirements:

Verifying that the Energy Audit measures recommended for implementation by NEAT, MHEA or TREAT audit have individual SIRs of 1.0 or greater. Energy Audit measures with an SIR of less than 1.0 must not be implemented. Installing a measure with a lower SIR without installing others with greater SIRs is not allowed.

Verifying and documenting that, in addition to the measures that are required to be implemented based on the Energy Audit, all additional weatherization requirements included in the Installation Standards are implemented. Any exceptions associated with not completing recommended or required measures must be appropriately documented in the client's file.

Verifying that all Energy Audits are completed using the Key Parameters and Default Parameters established by the Nebraska Energy Office with no modifications unless authorized.

Note: Blown fiberglass insulation is non-corrosive to metal skinned manufactured housing and can achieve good R-values and convection resistance at lower densities and weights that won't cause damage to the interior sheeting or underbelly of the home. Installations that include cellulose insulation may be completed only after warrantee information is provided by the installer ensuring no future damage to either the ceiling or underbelly of the home as a result of the use of cellulose insulation.

Energy Audits determine what energy efficiency measures must be implemented. The Installation Standards determine how Energy Audit measures are to be implemented.

Verifying that Ineligible Materials/Measures, as listed below, are not recommended for implementation or installed:

Verifying that, pursuant to DOE Guidance:

All multi-family projects must be submitted to the Nebraska Energy Office as per the U.S. Department of Energy's Multi-Family Review Protocol revised on November 1, 2011. Common areas in multi-family buildings may be weatherized like the closest living unit.

Verifying and documenting all incidental repair costs necessary for the installation or preservation of a weatherization measure. Keeping in mind that:

Verifying that the home complies with ASHRAE Standard 62.2 and DOE Guidance Requirements

1.03 Deferrals

The decision to defer work in a dwelling is difficult but necessary in some cases. Sub-grantees are expected to pursue reasonable options on behalf of clients and to use good judgment in dealing with difficult situations. Deferral conditions may be found in the Health & Safety Section 2 of this Installation Standard. Should any dwelling be determined to be a deferral:

A "walk-away/deferral" is not a completion. Reimbursement for "walk-away/deferral" must be obtained through the normal monthly billing process. Indicate on the BCJO (Building Check Job Order) that the dwelling is a "walk-away/deferral" and the client was advised in writing of the conditions determining this status.

Defer all units undergoing remodeling or which h ave untreated remodeled areas that directly affect the weatherization process.

1.04 Client Education

The NeWAP provides sub-grantees with an opportunity to educate clients and provide them with some simple, easy and inexpensive energy saving tips to help them save additional energy while improving comfort.

1.0401 Heating and Cooling Saving Suggestions:

1.0402 Hot Water and Laundry Saving Suggestions:

1.0403 Other Energy Saving Opportunities:

1.0404 Health & Safety Educational Material

The NeWAP requires that all clients be provided with educational material specifically associated with Health & Safety issues with documentation of receipt included in the client file.

2 Health & Safety

Health & safety measures must be performed in conjunction with cost-effective weatherization. Allowable health and safety activities are those that eliminate hazards that are affected or caused by the installation of weatherization materials.

Major hazards and potentially life-threatening conditions must be corrected before weatherization installers can work in the dwelling unless the installers are making the corrections.

When a weatherization agency finds serious safety problems in a customer's home, they must inform the customer in writing about the hazards.

When Not to Weatherize a Dwelling

There are some conditions and situations under which a sub-grantee must not or may choose not to weatherize an otherwise eligible dwelling unit. Information for making this determination may become evident during either the eligibility process or during the initial inspection. If the sub-grantee makes a determination that there are circumstances that prevent the weatherization process from proceeding, they must:

At the time of application, the applicant is given a written notice outlining the applicant's rights and the method to file a complaint. All sub-grantees are required to adhere to their agency's grievance polices. If the grievance cannot be resolved through the sub-grantee's process, the applicant will file a complaint with the Nebraska Energy Office.

A sub-grantee must not weatherize if:

A sub-grantee may choose not to weatherize a dwelling unit if:

Client Health & Safety

There are a number of important health and safety issues related to weatherization work that can impact weatherization emplo yees as well as clients. When any of these issues are detected, the client must be informed of the issue and, if possible, addressing these problems should be a top priority.

HEALTH AND SAFETY ASSESSMENT

Energy Auditors and crews/subcontractors are required to take all reasonable precautions against performing work on homes that will subject workers or clients to health and safety risks. The initial home inspection must include a health and safety assessment of the dwelling. The assessment must include interviewing the client regarding known health concerns, inspecting the dwelling for present or potential moisture concerns, indoor air quality concerns and other environmental concerns or hazards that may or may not be covered by the NeWAP.

In addition, clients will receive the following publications or documents when applicable:

Sub-grantee personnel will interview and assist clients in completing a Health & Safety Home Screening Questionnaire (Form WX7) as part of the application process. The survey will be included in the client file for future reference. The Energy Auditor will then review the Questionnaire with the client at the time of the initial assessment. The information collected during this process will be used in determining the best course of action for weatherization of the home. When a client's health is fragile and/or the weatherization activities would constitute a health or safety hazard, the occupants at risk will be required to leave the home during the activities and requested to return at least 1 hour (or a reasonable time as determined by the installers) after installers are scheduled to leave to allow for clean-up and appropriate ventilation of the home.

If it is determined through the Health & Safety Home Screening Questionnaire (Form WX7) that someone in the home is sensitive to a product that is intended to be used during the weatherization process, the sensitivity must be documented in the file and, if possible, an alternative product may be used. If no successful alternative is found, the weatherization of the home may proceed without completion the measure with no impact on weatherization measures with lower SIRs, with prior Nebraska Energy Office approval.

Weatherization funds cannot be used to relocate clients or reimburse them for such costs incurred as a result of the requirement to leave during the day. If the client is unable to leave the home and the intended work may exacerbate an occupant's health condition, the home may need to be deferred.

Sub-grantees must take all reasonable precautions against performing work on homes that would subject clients to health and safety risks.

2.01 Safe Work Practices

Worker Health & Safety

Weatherization staff are vitally important and staff must not be required to work in unsafe and/or excessively unsanitary conditions. Costs related to Grantee Health & Safety training must be charged to Training & Technical Assistance.

NeWAP sub-grantees Trained Weatherization Staff or Qualified Heating Technician must complete inspections, testing and assessments on all combustion appliances within a home to ensure all equipment is operating safely.

2.0201 Combustion Safety General

Leak Test Gas Appliances and Piping

Conduct a fuel leakage test of the appliance piping and control system downstream of the meter to each appliance. Natural gas and propane piping systems may leak at their joints and valves. An electronic combustible gas detector (gas sniffer) will find all significant gas leaks if used carefully. Remember that natural gas rises from a leak and propane falls, so position the sensor accordingly.

5.3003.4 (a, b, c, d, e, f, g, h) Heating & Cooling - Forced Air - System Assessment & Maintenance - Evaluating Electrical Service (SF)

Verify, Assess and Document Adequate Combustion Air Supply for All Combustion Zones

Combustion appliances required oxygen or combustion air to operate and some appliances draw combustion air from inside the home or building envelope. Completing an assessment on each combustion appliance in a home ensures that a combustion air problem does not interfere with combustion, create carbon monoxide or contribute to spillage or backdrafting.

Combustion appliance zones are classified as either un-confined spaces or confined spaces.

2.0203.1 (a, b) Health & Safety - Combustion Safety - Vented Gas Appliances - Combustion Air for Natural Draft Appliances (SF)

NeWAP sub-grantees must verify and document in each client file that each combustion appliance zone in a weatherized home has adequate combustion air supply.

When additional combustion air is required the following options must:

Manufactured housing specific work standards

The costs associated with installing the make-up fresh air must be charged to Health & Safety.

Combustion Appliance Zone ( CAZ ) Testing

NeWAP sub-grantees must complete CAZ  testing on all areas within a home that contain one or more atmospherically vented combustion appliances. CAZ  testing must be completed on all weatherized homes, at the time of the initial and Quality Control Inspections, with all testing results documented in the client file using CAZ Depressurization Test Form (WX9).

CAZ  testing must include, but not be limited to:

2.0201.1 (a, b, c, d, e, i) Health & Safety - Combustion Safety - Combustion Safety General - Combustion Appliance Zone ( CAZ ) Testing (SF) (MH)

Investigate Improving Inadequate Draft

If measured draft is below minimum draft pressures, investigate the reason for the weak draft. Open a window or door to observe whether the addition of combustion air will improve draft.

Combustion Applicance Zone Carbon Monoxide Testing

Ambient CO levels should be monitored in the combustion zone during draft testing. If ambient CO levels in the combustion zone exceed 35 parts per million (ppm), draft tests should cease for the technician's safety. The combustion zone should be ventilated before draft-testing and diagnosis of CO problems resumes.

2.0817 Lead Based Paint

Lead-Safe Weatherization (LSW) is a group of safe practices used by weatherization technicians when they suspect or confirm the presence of lead paint. LSW practices are rigorous dust-prevention and housekeeping precautions. LSW is required when workers disturb painted surfaces by cutting, scraping, drilling, or other dust creating activities.

On April 10, 2010, the Environmental Protection Agency (EPA) Lead; Renovation, Repair and Painting Program (LRRPP) Final rule became effective in the Weatherization Program. The rule requires Certified Renovators to be onboard with sub-grantee crews or contractors, and performing all the EPA required functions on all pre-1978 housing. The U.S. Department of Energy requires sub-grantees to follow specified EPA requirements. By adopting basic safety precautions and Lead Safe Weatherization, workers and the occupants of the homes they weatherize will be protected from lead exposure. The U.S. Department of Energy requires sub-grantees to follow specified EPA and Occupational Safety and Health Administration (OSHA) standards for worker safety.

2.0818 Mold and Moisture

Water moves easily as a liquid or vapor from the ground through porous building materials like concrete and wood. A high groundwater table can channel moisture into a home. The most common ground-moisture source is water vapor rising through the soil or liquid water moving up through the soil by capillary action. To prevent this, all crawl spaces should have ground moisture barriers.

Installing or improving air barriers and vapor barriers to prevent air leakage and vapor diffusion from transporting moisture into building cavities.

Adding insulation to the walls, floor, and ceiling of a home will keep the indoor surfaces warmer and less prone to condensation. During cold weather, well-insulated homes can tolerate higher humidity without condensation than can greatly impact poorly insulated homes.

General Information:

Sub-grantees must ensure that weatherization work is performed in a manner that does not cause or contribute to mold problems, and when the work is performed properly, may alleviate mold conditions.

3 Air Sealing

Air infiltration can account for 30 percent or more of a home's heating and cooling costs and can contribute to additional problems with moisture, noise, dust, indoor air quality, and pests. Appropriate air sealing can reduce infiltration significantly to reduce heating and cooling costs, improve building durability and longevity, and create a healthier indoor environment.

3.01 Identify the Air and Thermal Boundaries of the Building Envelope

To complete appropriate air sealing you must identify the location of both the air and the thermal boundaries of the home. Generally, ceilings, walls, and floor/foundation separate the inside conditioned space from the outside or unconditioned space forming both the air barrier and the thermal barrier for the house, but that is not always the case. For example, the thermal boundary of a home's crawl space may be insulation located in the floor cavities while the foundation walls actually provide the air barrier. A visual inspection is used to verify the thermal barrier while blower door testing of the pressure planes within the home is one of the most accurate ways of identifying the air boundaries of a home.

3.02 Blower Door Testing

Blower door testing is used to determine the overall air tightness of a home. Appropriate testing can help you to locate leaks, determine approximately how big the leaks are, and whether the leaks are located in areas that may significantly impact the indoor air quality of the home and the health of its residents. Pre- and post-weatherization blower door testing must be completed on all homes weatherized through the NeWAP. Documentation of the test results must be appropriately included in all client files.

2.0103.1 (a) Health & Safety - Safe Work Practices- Air Sealing - Air Sealing Worker Safety (SF) (MH)

Air Sealing is most effective when completed in conjunction with the blower door. Utilizing blower door guided air sealing allows you to locate and seal the largest sources of leakage and helps you to determine the effectiveness of your sealing work by providing an instantaneous reduction in the home's CFM50 Reading. The CFM50 Reduction should be checked at the end of each air sealing measure or step completed to determine cost effectiveness. As the air sealing work progresses the amount of CFM reduction experienced diminishes, you are able to determine the point where continued air sealing is no longer cost-effective.

Cost Effective Blower Door Guided Air Sealing is air sealing guided by calculating effectiveness after each or round of infiltration repair work completed. Dividing the labor and material costs incurred by the CFM50 Reduction gives dollar/CFM50 savings ratio. As long as the dollar/CFM50 savings ratio is less than $40.00 per 100 CFM, continue looking for air sealing opportunities. If the dollar/CFM50 Ratio is greater than $40.00 per 100 CFM, stop air sealing.

Objective(s):

Determine if existing conditions meet the combustion air calculation

Best Practice

G2407.5.1 (304.5.1) Standard method. The minimum required volume shall be 50 cubic feet per 1,000 Btu/h (4.8 m3/kW).

G2407.5.2 (304.5.2) Known air-infiltration-rate method. Where the air infiltration rate of a structure is known, the minimum required volume shall be determined as follows: For purposes of this calculation, an infiltration rate greater than 0.60 ACH shall not be used in Equations 24-1.

For appliances other than fan assisted, calculate volume using Equation 24-1.

Required Volume (natural draft) ≥ ((21ft 3/ACHn) * (Input (other) / 1,000BTU/hr))

Input (other) = All appliances other than fan assisted (input in Btu/h).

ACHn = Air change per hour under natural conditions

Standard:

100,000 BTUH Furnace Input 100,000 x .05 = 5,000 ft3

or 100,000/1000 = 100

100 x 50 = 5,000 ft3

Known infiltration rate method (assuming ACHn is .50 in this example):

((21ft3/.50)*(100,000/ 1,000BTU/hr)) = 4,200 ft3

Measure the CAZ width

Additional combustion air will be provided in accordance with 2012 IRC G2407 and authority having jurisdiction when necessary to solve spillage problems

Objective(s):

Ensure adequate combustion air for operation of the appliance

Before

After

Combustion appliances in a confined space

Additional combustion air supplied from high / low vents

Tools:

  1. Drywall saw
  2. Drill
  3. Tin snips
  4. Tape measure
  5. Wire cutters

Materials:

  1. Metal ducts
  2. 1/4" galvanized hardware cloth mesh
  3. Galvanized straps or L-brackets to secure high/low vents
  4. Screws
  5. Louvered grilles (optional)
  6. Louvered doors (optional)

Combustion appliances require 50 cubic feet of volume for every 1,000 Btuh input. If this is not available, provide makeup air in accordance with the IRC G.2407 or local code.

When high/low vents are used, use two metal ducts each having 1 in2 of cross-sectional area for every 4,000 Btuh input. Extend each into the attic above the insulation level, and use 1/4" galvanized hardware cloth mesh on top to screen out insects and vermin. Terminate one vent within 12 inches of the ceiling, and one vent within 12 inches of the floor. The vents may be concentric (one inside the other) to save space, so long as the difference between the area of the larger and smaller vents is equal to or greater than the 1 in2/4,000 Btuh requirement.

If using a single large opening in the ceiling, make the opening total 1 in2 per 3,000 Btuh input.

If high/low vents extend horizontally through a CAZ wall, use vents with 1 in2 of area per 2,000 Btuh of input.

Louvered grilles or doors may be used to connect the CAZ to larger sections of the home to achieve the required volume, but be aware that using this approach has higher potential for creating a carbon monoxide pathway into the home than does creating a sealed CAZ with high/low vents.

Select vent sizes based on the total input Btus in the CAZ. Concentric vents are shown

Cut hole in ceiling and mount high/low vents to framing

Fasten 1/4" galvanized hardware cloth over high / low vent openings
