Overview

The U.S. Department of Energy’s (DOE) Weatherization Assistance Program (WAP) and the National Renewable Energy Laboratory (NREL) developed the Guidelines for Home Energy Professionals project (hereafter Guidelines) to support and promote high-quality work within the WAP. NREL is a national laboratory of the DOE, Office of Energy Efficiency & Renewable Energy (EERE), operated by the Alliance for Sustainable Energy, LLC. EERE sponsored, funded, and provided oversight of the Guidelines project. The Guidelines are also a resource for workers, contractors, training providers, homeowners, and program administrators involved in the broader home performance industry where a comprehensive, whole-house approach to building science is required.

The Guidelines project is about achieving quality in any given home energy upgrade task. To do that, the Guidelines take a three-pronged approach:

Define the Work through Standard Work Specifications.
The Standard Work Specifications (SWS) for Single-Family, Multifamily, and Manufactured Housing Energy Upgrades define the minimum acceptable outcomes for any weatherization or home performance task to be effective, durable, and safe.
Validate the Training through Job Task Analyses.
Job Task Analyses (JTAs) for the four major energy upgrade job classifications define what a worker needs to know and do to be successful. These JTAs cover job tasks for retrofit installer/technician, crew leader, energy auditor, and quality control inspector. The accreditation of energy efficiency training programs verifies that organizations training workers in the industry are qualified to teach to the JTAs.
Certify the Worker through the Certification Blueprints.
The certification blueprints synthesize SWS content and the JTAs to lay out a roadmap for developing robust worker certifications. The four Home Energy Professional worker certifications are part of and are aligned with the Guidelines efforts and target a worker’s capacity to demonstrate practical ability to perform the work of the industry.

The Guidelines project allows industry to leverage these three components to develop SWS-based training resources, quality assurance protocols, accredited training programs, and professional certifications. These tools will facilitate the development of a highly qualified work force, demonstrate worker qualifications to employers and homeowners, and enable the industry to validate the quality of its work.

Background

The Guidelines project is supported by the WAP’s National Training and Technical Assistance Plan, which supports the high-quality work performed in the WAP through the development of technical tools and resources built upon the WAP’s 30+ years of leadership in home energy upgrade work. The SWS were developed in response to a need identified by WAP technicians and program administrators for a document that would define the technical requirements of the work performed by the program.

The Guidelines development process is a historic collaboration between WAP technicians and trainers, home performance contractors, building scientists, organized labor, and other professionals throughout the home energy upgrade industry. In addition to the involvement of residential energy efficiency professionals, staff from the Environmental Protection Agency (EPA), the Occupational Safety and Health Administration (OSHA), and the National Institute for Occupational Safety and Health (NIOSH) participated in writing and reviewing the Guidelines to cover worker and occupant health and safety. The Department of Housing and Urban Development (HUD), Department of Agriculture (USDA), and the Department of Labor (DOL) have also been key partners in the development of the Guidelines.

This document is being disseminated by DOE. As such, the document was prepared in compliance with Section 515 of the Treasury and General Government Appropriations Act for Fiscal Year 2001 (Public Law 106-554) and information quality guidelines issued by DOE. Should this document constitute “influential” information, as that term is defined in DOE’s information quality guidelines or the Office of Management and Budget’s Information Quality Bulletin for Peer Review (Bulletin), the document meets the prior peer review pursuant to Section II.2 of the Bulletin. Additionally, the document was reviewed both internally and externally prior to publication. For purposes of external review, the document benefited from review through the public comment process.

Section 1: Using the Standard Work Specifications for Home Energy Upgrades

The SWS synthesize more than 30 years of building science expertise within the WAP program and the greater industry by identifying the desired outcomes of the individual measures performed during a whole-building energy upgrade. They combine original content with references to relevant codes and/or technical standards that currently exist as independent, stand-alone documents.

Definition of Multifamily Housing

The definition of multifamily housing used for the SWS is: any dwelling that contains five or more living units, which share one or more building systems and has three categories:

Low-rise: 1-3 stories with any shared building system

Mid-rise: 4-5 stories with any shared building system

High-rise: 6 stories or greater

Definition of Manufactured Housing

The definition for manufactured housing as used in the Manufactured Housing SWS document is: a single-family home that contains a permanently affixed chassis, allowing the dwelling to be transported by road. Traditionally, these homes have been called mobile homes and, in essence, the Manufactured Housing SWS document is using the term “manufactured housing” synonymously with “mobile homes.”

The Whole-House/Building Assessment

The whole-house/building assessment or energy audit is a vital component of the home energy retrofit process. It is imperative that an assessment of the whole-house/building is performed by a qualified auditor who is following a high-quality audit procedure recognized by the WAP or other program sponsor. Once the auditor has conducted a whole-house/building assessment and has developed a list of recommended measures, the SWS can be used to identify the desired outcomes of those measures and to assess the quality of the completed work. The SWS document is not meant to replace existing engineering and design specifications, but rather to be complimentary.

The Components of the SWS

The SWS identify the desired outcomes of a particular energy efficiency measure. They define the outcomes, stated as objectives, and then list the minimum specifications that are necessary for a properly installed measure to meet those outcomes (see sample specification).

Sample Specification

Sample specification

SWS Numbering Scheme

The details within the SWS have been indexed and numbered in a way that provides readers with suggestions as to what is contained in a specific detail, and allows for additions as the document expands without disrupting the numbering sequence. The SWS are organized into four layers. From general to specific, those layers are section, topic, subtopic, and detail. Each section contains multiple topics, each topic may be further divided into subtopics, and each subtopic contains one or more details.

Dissecting a Detail Number

Numbering scheme

There are seven sections in the SWS:

Using the Standard Work Specifications
Health and Safety
Air Sealing
Insulation
Heating and Cooling
Ventilation
Baseload

The section number is the first digit of a given detail. As illustrated above, any detail number beginning with 3 is from Section 3—Air Sealing.

Within each section, another set of numbers has been assigned to topics. These are represented in the first two digits in the second number in the detail titles. Some numbers are not yet in use but are reserved for future expansion of the SWS. In the example shown above, .10XX indicates that the detail is in the topic “Attics.” A detail related to insulating attics would be 4.10XX.X. For example, 4.1001.4 Vented Eave or Soffit Baffles.

Here is a full list of topic designations:

.0100 - .0900 – Health and Safety Issues

.0100 Safe Work Practices
.0200 Combustion Safety
.0300 Safety Devices
.0400 Moisture
.0500 Radon

Used at the topic level, it looks like this:

6.9901.1 Supplemental Ventilation Information - ASHRAE 62.2

This is the first detail in Section 6—Ventilation, topic .99 Additional Resources, subtopic 01 Codes and Standards Resources.

Used at the subtopic level, it looks like this:

6.6288.1 Sound Rating Limits

This is the first detail in Section 6—Ventilation, topic .62 Whole Building, subtopic 88 Special Considerations.

Codes and Standards

While the SWS will help identify the desired outcomes of energy efficiency measures in a weatherization or home energy upgrade project, they are not a replacement for the codes and/or technical standards mandated by a particular jurisdiction or a replacement for the manufacturer’s stated installation requirements. State, local, or municipal code or ordinance has legal precedence and users should obtain copies of the applicable codes and standards for their jurisdiction before performing the work.

Numerous national standards bodies have provided significant insight and input on the SWS. The following serve as the primary referenced codes and standards. In order to limit redundancy, additional standards that are already referenced in the following codes are not restated within the Guidelines. However, when a standard is not addressed by the following codes, it is referenced within the Guide to Referenced Standards section as an additional resource. It is important to note that references to codes and standards within the SWS documents do not constitute an endorsement by the WAP.

IBC (International Building Code)
IECC (International Energy Conservation Code)
IFGC (International Fuel Gas Code)
IMC (International Mechanical Code)
IPC (International Plumbing Code)
IRC (International Residence Code)
NFPA 54 (National Fuel Gas Code)
NFPA 70 (National Electrical Code)
NPFA 31 (Standard for the Installation of Oil-Burning Equipment)
UMC (Uniform Mechanical Code)
UPC (Uniform Plumbing Code)

When codes and standards are referenced in the SWS, the year of the reference is not included. The reader should refer to the most recent version of the reference that is currently published.

Standards are referenced in two ways:

Embedded in the specification in either the objective or specification column. This indicates that the referenced standard is a representative approach to meet the specification.
Listed in the Guide to Referenced Standards.

The Role of the U.S. Environmental Protection Agency Healthy Indoor Environment Protocols for Home Energy Upgrades in the SWS

DOE and the EPA have collaborated closely throughout the production of the Guidelines and EPA’s Healthy Indoor Environment Protocols for Home Energy Upgrades. In particular, the two agencies have strived to ensure that the majority of the EPA minimum actions are fundamentally integrated and referenced as appropriate in the Standard Work Specifications. The intent is that upgrade workers following the DOE document will inherently achieve most of the EPA minimum recommendations.

The EPA protocols can be located at: www.epa.gov/iaq/homes/retrofits.html and should be referenced and utilized by energy upgrade workers.

The EPA protocols also provide additional detailed information on healthy retrofit practices and address some situations not specifically covered in the SWS including below-ground contaminants from sewer gases and soil or groundwater contamination, building products/ materials emissions, and removal of fluorescent light ballasts containing polychlorinated biphenyls (PCBs). Additionally, both DOE and the EPA fully support the upgrade industry going above and beyond the minimum requirements by adopting the EPA-recommended expanded actions. Both agencies also understand that financial or programmatic constraints may impede this in certain cases.[1]

The EPA Healthy Indoor Environment Protocols for Home Energy Upgrades focus primarily on the health and safety of the building occupants. The EPA document includes recommended assessment protocols to identify indoor environmental quality issues, recommended minimum actions, and opportunities for expanded actions to promote improved occupant health through home energy upgrades. Each of these is described below.

Assessment protocols provide EPA-recommended protocols for evaluating both existing conditions of concern and the potential for additional health concerns that may arise as a result of upgrade activities.
Minimum actions include actions that weatherization and home energy upgrade contractors should take to help ensure that the work they perform in a home does not introduce new health concerns or make existing conditions worse. These often reference existing national standards; however, work should be conducted in compliance with state and local requirements as well.
Expanded actions include recommended further indoor environment improvements that can be made during many home energy upgrade projects. The expanded actions are improvements that can be performed by home energy upgrade workers with proper training and sufficient resources. National standards and guidance are referenced; however, work should be conducted in compliance with state and local requirements as well.

The Importance of Qualified Professionals

It is important for the user to understand the necessity of ensuring that all contractors undertaking the work outlined in the SWS are properly qualified. There are a number of certification bodies and industry groups that provide verification of an individual’s qualifications to perform certain types of work. This is particularly important in tasks related to heating, ventilating, and air conditioning (HVAC), electrical systems, and plumbing. Professional contractors who are credentialed through well-established national organizations can help ensure that this work is performed safely and correctly. There are often licensure requirements at the state or local level.

Within the SWS, there is a note placed in each detail in which a licensed or credentialed professional may be required to perform certain tasks. The reader is encouraged to ensure that all work is carried out in accordance with requirements set forth by the authority having jurisdiction

The WAP requires its contractors to adhere to all codes, licensing, and certification requirements in the jurisdiction in which they operate.

[1] Weatherization Program Notice 11-6 provides information related to the implementation and installation of health and safety measures as part of the WAP. This guidance makes available recommendations to WAP Grantees as they develop their Health and Safety (H&S) Plans and procedures. The guidance also provides clarity to grantees on H&S measures and costs that are allowed as part of this energy program. WPN 11-6 (Program Year 2011, the “dash 6” will be the reference for subsequent H&S guidance in future program years) is available at www.waptac.org under rules and guidance.

General Information on Spray Polyurethane Foam (SPF)

Low-Pressure SPF SPF Spray polyurethane foam

Low-pressure SPF SPF Spray polyurethane foam systems are two-component polyurethane foam products. They are typically delivered to the job site in pressurized canisters (~250 psi Psi Pounds per square inch ), dispensed though unheated hoses through a disposable mixing nozzle system, and applied as a froth-like material to substrate. This type of SPF SPF Spray polyurethane foam product is typically used for large sealing and small-scale insulation products.

High-Pressure SPF SPF Spray polyurethane foam

High-pressure SPF SPF Spray polyurethane foam systems are two-component polyurethane foam products. They are typically delivered to the job site in unpressurized drums or totes and dispensed by a proportioner pump where heat and pressure are added. These chemicals travel through heated hoses to a spray gun where the material is aerosolized during application. This type of SPF SPF Spray polyurethane foam product is typically used for larger insulation applications.

Note on SPF SPF Spray polyurethane foam Delivery Methods

Once installed, there is essentially no difference in product performance between low- and high-pressure foams. It should be noted that the main differences between the delivery methods are in capital equipment investment, application rate, and PPE PPE Personal protective equipment requirements.

Installer Training

Applicators should obtain training from the suppliers of SPF SPF Spray polyurethane foam to help assure installation quality and use of all equipment as well as safe handling, use, and disposal of all chemicals used in the process. Spray Polyurethane Foam Alliance ( SPFA SPFA Spray Polyurethane Foam Alliance ) also offers additional training and accreditation for high-pressure SPF SPF Spray polyurethane foam applicators.

Manufacturer Installation Instructions

SPF SPF Spray polyurethane foam applicators should follow all manufacturer installation instructions for the product being used. These instructions include product-specific documents such as application instructions, MSDSs, and evaluation reports.
