Implementing Identified Performance Improvements 6.0

IIPI Insulation 6.4

IIPI Insulation The Technician must make sure that the insulation is installed using the insulation manufacturer’s procedures and instructions. Applicable recommendations should be followed when provided by:

IIPI Insulation The Insulation Contractors of Association of America, Spray Polyurethane Foam Alliance, Blown-in-Blankets Contractors Association, and/or Structural Insulated Panel Association.

IIPI Insulation The following standard installation procedures need to be followed for the specific applications listed: ASTM C Standard Specification for Spray-Applied Rigid Cellular Polyurethane Thermal Insulation. ASTM C Standard Practice for Installation of Mineral Fiber Batt and Blanket Thermal Insulation for Light Frame Construction.

IIPI Insulation Other items the Technician must consider when installing or repairing insulation include: Any existing interior or exterior moisture issues must be remediated prior to insulating the building shell. Whenever an enclosed cavity insulation upgrade covering 15% or more of the total building shell area is part of the home improvement’s upgrade plan, the Technician must perform a pre-and post-installation envelope leakage testing.

IIPI Insulation Vented eave or soffit baffles must be mechanically fastened to block wind entry into insulation, or to prevent insulation from blowing back into the attic. Baffles need to be installed to maintain clearance between the roof deck and baffle according to manufacturer specifications. Installation of the baffles will allow for the highest possible R-value above the top plate of the exterior wall.

IIPI Insulation When cellulose is used as fill over pitched ceilings: o Only stabilized products are allowed to be used. o Loose fill fiberglass will only be used on a slope less than or equal to a 6:12 pitch, or the slope application approved by the manufacturer, whichever is less. o Roof cavities will be insulated with loose fill according to manufacturer specifications without gaps, voids, compressions, misalignments or wind intrusions. o Insulation will be installed to contractual R-value.

IIPI Insulation Using fill tube, for dense pack over pitched ceilings, requires that 100% of each cavity will be completely filled to a consistent density that meets the following requirements: o Cellulose material will be installed to a minimum density of 3.5 pounds per cubic foot. o Loose fiberglass material will be installed and will be specifically approved for airflow resistance to a minimum density of 2.2 pounds per cubic foot.

IIPI Insulation Note: The number of bags installed will be confirmed and will match the number required based on the insulation manufacturer’s coverage chart. Additionally, for this type of application, insulation will be verified to prevent visible air movement using chemical smoke at 50 Pa of pressure difference.

IIPI Insulation Unvented flat roof cavities with existing insulation may be repaired using blown-in, loose fill insulation to fill all gaps, voids, compressions, misalignments or wind intrusions. The blown-in insulation will be installed to the prescribed R- value for the entire roof cavity where the repairs are being made.

Insulation Documentation Documentation of type of insulating material and it’s R-value (see Appendix 2) will be provided to the homeowners in accordance with 16 CFR (CFR). The CFR is a law that states the installer must give the customer a contract or receipt that states the following for each area insulated and for each different type of insulation:

Insulation Documentation o Coverage Area. o Thickness. o R-Value. o Date. o Installers Signature.

Insulation Documentation For Loose fill Insulation, the additional requirements that must be included are: Installed thickness. Minimum settled thickness. Number of bags used (copy of receipt when available). For aluminum foil the additional requirements that must be included are: Number and thicknesses of air spaces. The direction of the heat flow.

IIPI HVAC 6.5

IIPI HVAC New HVAC systems must be installed in accordance with the ANSI/ACCA 5 QI (HVAC Quality Installation Specification). Technicians should use the Technician’s Guide & Handbook for Quality Installations as a reference for HVAC design, installation, testing, and documentation requirements and approved procedures.

IIPI HVAC Additionally, when maintenance items or cleaning of an existing system is required, the following methods should be used: Maintenance performed on existing HVAC systems shall be in accordance with ACCA 4 QM Standard (Maintenance of Residential HVAC Systems).

IIPI HVAC Restoration of existing HVAC systems beyond the scope of the ACCA 4 QM Standard shall be conducted in accordance with ACCA 6 Quality Restoration.

IIPI HVAC The leakage rate of heating/cooling ducts specified for sealing shall meet the tightness standards specified in §5 of the ANSI/ACCA 5 QI – 2015, or by the AHJ, and shall be established by measurements post- remediation.

IIPI HVAC Heating/cooling ducts specified for sealing and located outside the building’s envelope, or cooling ducts that are located in attic spaces, shall be sealed at the air barrier at all accessible connections and insulated in accordance with IECC 2012.

IIPI HVAC New ventilation systems shall be installed per the OEM instructions, and leakage rates must meet §5 of the ANSI/ACCA 5 QI – 2015/ or the AHJ’s requirements. Where specified in the contract, the ducts must be balance in accordance with the designer’s intent utilizing procedures specified in the ANSI/ACCA 5 QI – Note: the Technician’s Guide & Workbook for Quality Installations covers these procedures.

IIPI HVAC Existing venting for bathrooms and kitchens shall comply with the 2012 International Residential Code §M1507 which for residential applications requires: o bathroom venting minimums of 50 CFM intermittent, or 20 CFM for continuous fan operation. o kitchen venting minimums of 100 CFM intermittent, or 25 CFM for continuous fan operation.

IIPI Moisture and Pools & Spas 6.6 & 6.7

IIPI Moisture Water savings may be addressed through fixture upgrades or through other water saving measures. For example, rain water storage for landscape watering where allowable by code.

IIPI Moisture Where moisture problems exist, the Technician must recommend a fix for the moisture-related problems through the elimination of the source, isolation of the source, or ventilation of the space around the source before other envelope/shell-related measures are started during the home performance upgrades.

IIPI Moisture Samples of Moisture Repairs

Pools & Spas Safety first for pools and spas. All of the suction outlet covers need to be installed in accordance with ASME A

Pools & Spas When upgrading for efficiency is part of the home’s contract, the energy efficiency of pool filter pumps, controls, and heaters must be in accordance with Association of Pool and Spa Professionals (APSP) 15 standard.

Pools & Spas Generally, the Technician will install the pumps and filters provided by the pool supply house. Thus, the Technician needs to make sure that the purchased equipment’s documentation states that the equipment meets the APSP energy efficiency requirements for the pipe sizing and GPM as found/built for the home’s pool/spa.

Pools & Spas Related equipment includes the following: Controls, timer switches, and covers shall be per 2012 IECC (2009) §403.9 Pools (Mandatory): o Gas pool heaters must not have a standing pilot, and all pool heaters must have a shut off switch that is separate from the control thermostat.

Pools & Spas o Heaters and pumps must have timer switches installed so they can be operated based on time of day, unless they are required for solar heating, waste-heat-recovery, or when 24-hour pumping is required by code. o All heated pools need to have a vapor-retardant pool cover that contacts the surface of the water. Covers for pools/spas heated 90 O F, or warmer, need to have an insulation value of at least R-12, unless 60% or more of the heat comes from a solar collector.

Pools & Spas Vapor retardant covers on heated pools shall be tested and listed in accordance with ASTM F – 2010 Standard Performance Specification for Safety Covers and Labeling Requirements for All Covers for Swimming Pools, Spas and Hot Tubs. The Technician needs to check and see if existing covers have the ASTM labels, and to make sure any new cover being installed has an ASTM label New or replacement HVAC systems serving indoor pools and spas shall be designed per ACCA Manual SPS 2010 HVAC Design for Pools and Spas.

Pools & Spas New pools or spas shall be constructed in accordance with the applicable APSP standard. The Technician needs to make sure that the pool construction company understands this requirement and builds a pool that meets this requirement. Note: if you get a call to build a pool, you might want to pass. Building a new pool is beyond the scope of home performance upgrades and will not save energy or water.

Pools & Spas Design Guidance
