CALIFORNIA STATEWIDE UTILITIES CODES AND STANDARDS PROGRAM PIER Study Acceptance Testing Current Code Requirements (Mandatory) ● § 125 Acceptance requirements ● Functional tests (performance verification) performed on select lighting, envelope, & HVAC systems ● Acceptance tests are conducted: ● ● After construction and start-up Before occupancy and normal use of the equipment ● Who can perform the tests: ● Licensed mechanical engineer, civil engineer, architect or contractor Date 3

CALIFORNIA STATEWIDE UTILITIES CODES AND STANDARDS PROGRAM PIER Study Acceptance Testing Current Code Requirements (Mandatory) ● NA 7. 5. 4 Air Economizer Controls Acceptance Test ● ● In-field functional tests 1. Cooling demand, economizer 100% open 2. Cooling demand, economizer @ minimum position 3. Heating demand, economizer @ minimum position If the economizer is factory installed and certified by the manufacturer to the CEC, no field testing is required Date 4

CALIFORNIA STATEWIDE UTILITIES CODES AND STANDARDS PROGRAM PIER Study Acceptance Testing Typical Practice ● Performance verification is uncommon ● Low compliance and enforcement ● Responsible party not specified on forms (MECH-1 C) ● Building officials not requesting/checking forms ● Building departments are underfunded and understaffed ● Reduced/eliminated training budgets ● Outsourcing plans examinations ● Inspectors not familiar with requirements ● Contractors unfamiliar with tests Date 5

CALIFORNIA STATEWIDE UTILITIES CODES AND STANDARDS PROGRAM PIER Study Acceptance Testing Code Change Proposals ● Increase compliance and enforcement ● ● Improve test protocols Modify as needed: ● ● ● code language test forms compliance manual reporting procedures enforcement procedures Outreach and education activities ● MEP firms involved with plans examinations Date 6

CALIFORNIA STATEWIDE UTILITIES CODES AND STANDARDS PROGRAM PIER Study Acceptance Testing Code Change Proposals ● Responsible Person’s Declaration Statement ● Allow only a licensed contractor ● Prohibit architect and engineer ● Maintains pathway of professional qualifications ● Improves the pathway to accountability ● CEC to retain electronic copies of Certificate of Acceptance documentation ● Similar to document registration procedures introduced for residential projects Date 7

PIER Study Acceptance Testing CALIFORNIA STATEWIDE UTILITIES CODES AND STANDARDS PROGRAM Data Collection and Analysis Date 10

CALIFORNIA STATEWIDE UTILITIES CODES AND STANDARDS PROGRAM PIER Study Acceptance Testing Specifics of Code Change Proposals MECH-2 A Outdoor Air Acceptance Tests Construction Inspection: ● Added reference to conducting MECH-7 A with MECH-2 A. ● Added details to Instrumentation that is needed to conduct the test. ● Added supporting documentation for reference including Standards and Nonresidential Compliance Manual. ● Added information under VAV checklist to be consistent with At-a-glance forms. ● Added information regarding fixed outside air damper as opposed to dynamically controlled damper. ● Added a notes section under construction inspection for contractor comments. Date 11

CALIFORNIA STATEWIDE UTILITIES CODES AND STANDARDS PROGRAM PIER Study Acceptance Testing Specifics of Code Change Proposals MECH-2 A Outdoor Air Acceptance Tests Functional Testing: ● Edited formatting to be consistent with At-a-glance forms, i. e. step #’s. ● Added Mechanical Equipment Schedules as a reference document for design outside air requirements. ● Added “Record VFD speed” as part of procedure. ● Edited part B Testing Calculations & Results. Test required outside air measurement to be within 10% of design value. Test would fail if outside air was greater than 110% of design. Some systems in the field are not equipped with dynamic control of the outside air damper thus test would fail. Title 24 only requires minimum outside airflow. Therefore added note to the form to explain if the test fails because of too much outside air. Date 12

PIER Study Acceptance Testing CALIFORNIA STATEWIDE UTILITIES CODES AND STANDARDS PROGRAM Remaining Data Collection & Analysis ● Estimated energy savings ● ● Use ex-post evaluation of savings, which accounts for compliance Recover a portion of these savings due to improved testing guidance and increased compliance Date 13

PIER Study Acceptance Testing CALIFORNIA STATEWIDE UTILITIES CODES AND STANDARDS PROGRAM Connections to Design Phase Cx ● Incorporate tests into construction documents ● Responsible party specified on Cx plan ● Require the Cx Authority to collect/review forms Date 14
