Residential: Validation Approach 6/26/2014 Residential: Validation Approach Prescriptive Methods R-value Method U-factor Alternative Method Total UA Alternative Method Six single family detached home designs were formulated for testing the prescriptive methods. Each test case is evaluated using the three methods. The test methods, assumptions, evaluation results and procedures are summarized in a standalone spreadsheet (Since June 15, 2014 we combined house description, UA-Calculation, and Residential Prescriptive Compliance Test 2014). 9/22/2018

Prescriptive: R-Value Validation Software Vendor enter their results in the yellow cells Selects dropdown menu for most entries Must enter the software calculated average Fenestration U-Factor and SHGC List of mandatory requirements included For mandatory they can choose “Not Part of Software” If the software calculates all the expected results the “Test Results for Software” will “PASS” 9/22/2018

Prescriptive: U-Factor Validation Software Vendor enter their results in the yellow cells Selects dropdown menu for most entries Must enter the software calculated average Fenestration U-Factor and SHGC List of mandatory requirements included For mandatory they can choose “Not Part of Software” If the software calculates all the expected results the “Test Result ” will “PASS” 9/22/2018

Prescriptive: Total UA Validation 6/26/2014 Prescriptive: Total UA Validation Software Vendor enter their results in the yellow cells Must enter the software calculated total UA for the proposed and standard reference home We allow 2% Range for the total UA calculation knowing that software may use different properties for construction materials List of mandatory requirements included For mandatory they can choose “Not Part of Software” If the software calculates all the expected results the “Test Result ” will “PASS” 9/22/2018

Residential: Validation Approach Performance Method The five test cases were updated to test vendor’s software capability of generating the standard reference design from proposed design building only HVAC Equipment Performance Tests Hot Water System Performance Tests Duct Distribution System Efficiency Tests Five new tests were created to evaluate code compliance using e-Ratio method 9/22/2018

Performance Method: e-Ratio Test Test Description (New test cases created) Case L130A-01: Using the HERS BESTEST L130 case for Orlando, create a 3-bedroom Proposed Home containing the following equipment: Heating system – electric HP with HSPF = 7.7 Cooling system – electric A/C with SEER = 13.0 Hot Water – 40 gal electric with EF = 0.92 Equipment, Ductwork located inside the conditioned space and have zero (0) air leakage. Case L100A-02: Identical to Case L130A-01 except that the hot water heater is changed to a tankless natural gas with EF = 0.82. Case L100A-03: Identical to Case L130A-01 except that the space heating system is changed to a natural gas furnace with AFUE = 78%. Case L100A-04: Identical to Case L130A-01 except that the space heating system is changed to a high efficiency HP with SEER=17 and HSPF = 10. Case L100A-05: Case L130A-01 except the space heating system is changed to a high efficiency natural gas furnace with AFUE = 96%. 9/22/2018

Performance: e-Ratio Validation Acceptance Criteria: The reported Reference Home End Use Loads (REULs) vary by less than 0.2% across all cases. The difference between the e-Ratios calculated by the software tool and the e-Ratios calculated by the results spreadsheet provided by the Florida Building Commission is less than 0.5% for all cases. 9/22/2018
