Energy Program Instructions - WASHINGDDNSTATEUNNERSI9Y 2018 WSEC-Residential Energy Compliance Certificate The Washington State Energy Code (WSEC) requires a Code Compliance Certificate be permanently posted in all new dwelling units, per Section R401.3, including individual apartment units. The Certificate shall be completed (typically prior to occupancy) by the "builder or other approved party and posted in the space where the furnace is located, a utility room, or an approved location inside the building." The Certificate also provides important documentation related to the operations and maintenance instructions as required in Section R303.3 Maintenance information. The Certificate helps the builder and other stakeholders to confirm compliance with many (but not all) of the key WSEC-R requirements. Authorities Having Jurisdictions (AHJ) can compare information on the Certificate with approved design documents and on -site information. It provides critical information for the building owner, such as insulation installation, duct air sealing and testing &/or envelope testing affidavits or other documentation, and forms available at www.energycode.energV.wsu.edu. As well, a Certificate may provide helpful information for obtaining financing and insurance. The WSEC 2018 Certificate has ten parts, discussed in the sections below: • Property and builder/design professional information • R-values of walls, ceilings/roof, and floor, etc. • Tested or default U-values of windows, skylights and doors • Fuel normalization and energy credits • Heating, cooling and domestic hot water manufacturer and model • Onsite renewable energy electric power systems and energy savings documentation • Appliance manufacturer and model (refrigeration, dishwasher and clothes dryer) • HVAC system duct leakage testing affidavit • Building leakage testing test results form • Whole house ventilation system commissioning information Forms and affidavits to provide documentation of the information on the Certificate are available at www.energVcode.energV.wsu.edu and through manufacturers of testing and insulation.

Energy Program Instructions - WASHINGPDNSTATEUNNEpsny 2018 WSEC-Residential Energy Compliance Certificate HVAC System Duct Leakage Testing Thermal losses from ductwork are strongly dependent on where the ductwork and the air handler are located. If located within the conditioned spaces, air leaks and transmission losses from the air distribution system still serve to heat the dwelling unit. Leaky ducts located in unconditioned spaces can be one of the largest energy losses. HVAC System Duct Leakage Testing (R403.3) I Circle One All ductwork and air handler in conditioned space?

A date -stamped smart phone photo or air leakage testing software may be used to satisfy this requirement. Duct leakage testing determines how leaky the air distribution system is by pressurizing or depressurizing the ducts and air handler. In this section: • Enter the calculated design target leakage rate in CFM at 25 Pa. The design target HVAC system leakage test is 4 CFM per 100 square feet of conditioned floor area tested at 25 Pa, per Section R403.3.4. • Enter the measured HVAC leakage results from the blower door test in CFM @ 25 Pa. This value should be less than or equal to the target value. Building Leakage Testing In this section, results of building leakage testing are entered. Building leakage testing determines how leaky the dwelling unit is by depressurizing or pressurizing it with a device called a blower door. For R2 low-rise apartments, individual blower door tests are required only for garden -style apartments without corridors, per WSEC R402.4.1.2. For corridor buildings where results are performed for the whole building, enter the results of the whole building and add the note "whole building." M.

Whole House Ventilation System Enter data on ventilation fans and whole house ventilation, including results of flow testing of the whole house ventilation system. For R2 low-rise apartments, individual whole house ventilation system flow testing is required for each dwelling unit. No sampling of representative apartments is allowed.

To be correctly labeled, each switch, timer or other control shall have a permanently attached label identifying the fan it controls. Document that O&M instructions were provided to the building owner by circling Y or N. Provide the name of the person the instructions were provided to and the date of delivery. This is critical to ensure the current building owners and occupants understand how to maintain and operate the ventilation system as designed and installed. 7 Energy Program WASHINGPON STATE UNIVERSITY WHV System Type and Location Instructions - 2018 WSEC-Residential Energy Compliance Certificate Whole House Ventilation System Measured Flow Rates (M1505.41RC-WA) I Circle One Are the system controls correctly labeled?

Y or N (3) Supply or HRV WHV integral to the air handler. Describe system control sequence of operations or reference to design submittal: Identify the type of WHV system by circling one of the 3 types listed. For the selected type, enter its location per Table R403.6.1 (i.e., HRV, ERV, or WHV ventilation exhaust system. (A WHV ventilation exhaust may also provide bathroom, kitchen or utility ventilation requirements.) Balanced HRV and ERV systems will have both supply and exhaust fans and require that both airflows be documented. Please note any commissioning issues in the Commissioning Notes area. If the system is integral to the air handler, describe the system's control sequence of operation (SOO), or refer to design documents that provide the sequence of operation. The builder and/or the AHJ agent may want to verify SOO system performance as installed. WHV Run Time and Airflow Specify run-time: hours per day 100 CFM WHV calculated design minimum flow rate per plan submittal: WHV measured min flow rate at commissioning: Exhaust CFM, Supply CFM Do WHV flow tests include GPS & time stamp verification? Y or N Specify the run time in hours per day. If the system runs continuously, enter a run-time of 24 hours per day. Continuous operating systems require lower target design flow rates. Enter the calculated design minimum flow rate. To determine the target value, refer to Section M1505.4 Whole -house mechanical ventilation system of the Washington State Amendments of the 2018 International Residential Code for single family residences and dwelling units. For R2 low-rise apartments, refer to Section 403.4 Group R whole house mechanical ventilation system of the Washington State Amendments of the 2018 International Mechanical Code. Enter the measured minimum flow rate at commissioning of supply and exhaust fans, as applicable. This value should be equal to or greater than the design minimum flow rate. For balanced ERV and HRV systems, the supply and exhaust flow rates should be within 10% of each other or 5cfm whichever is larger. While this is required in the code, it is often hard to get a repeatable test at 5cfm. Circle Y or N to indicate whether the WHV system tests include GPS and time stamp verification. A date - stamped smart phone photo or air leakage testing software may be used to satisfy this requirement. Energy Program Instructions - WASHINGMNSTATEUNNERsny 2018 WSEC- Reside ntial Energy Compliance Certificate WHV Sensible Heat Recover Efficiency HRVIERV sensible heat recovery efficiency NA For HRV and ERV systems, enter the maximum rated sensible heat recovery efficiency, which is available in the Heating Ventilation Institute's certified products directory. From the HVI directory, use the Adjusted Sensible Recovery Efficiency (ASRE) at a flow rate that is no less than the design flow rate. When the design flow rate is between two listed flow rates in the HVI directory, interpolation of the ASRE shall be permitted. As an example, suppose a specifier selects an Alpha Model X13 HRV with a design flow rate of 70 cfm, listed as following in the HVI Section 3 Directory: Product Category Brand Name HRVs Alpha HRVs Alpha HRVs Alpha HRVs Alpha Model Temp Mod °C °F Net Airflow (Us) Net Airflow (cfm) WATTS SIRE ASRE X13 HEATING' 0' 32' 30' 64' 40' 71 76 X13 HEATING' 0 ' 32 ' 45 ' 95 ' 51 ' 69 ' 72 X13 HEATING' 0 ' 32 ' 55, 117 ' 60 ' 67 ' 70 X13 HEATING '-25 '-13 ' 32 ' 68 ' 52 ' 63 ' 65 For this case, the specifier may claim an ASRE of 72 (the highest ASRE associated with the rated flow that is no less than the design flow rate of 70 cfm) when complying with the "sensible heat recovery efficiency" requirement of Washington State's IECC-R Table R406.3; or, the specifier may interpolate to determine the ASRE between the rated flows that are greater than and less than the design flow (i.e., 64 cfm and 95 cfm are less than and greater than 70 cfm, respectively). Interpolating results in an ASRE of 75 for this case.
