1 ENERGY STAR Multifamily High Rise Program Testing and Verification Protocols Webinar – Part I July 2011

2 2 EPA Objectives for T&V Protocols Verify that the As-Built Building has successfully achieved the performance levels predicted by the Proposed Design energy model, or as specified in the Prescriptive Path, and is in compliance with the Prerequisites Checklist Work in conjunction with the ENERGY STAR MFHR Simulation Guidelines, Performance Path, Prescriptive Path, Testing & Verification Worksheets and Photo Template

3 3 EPA Objectives for MFHR Program Failure to comply with Prerequisites or Prescriptive Checklist: –Corrective action must be taken to bring the building into compliance with the Prerequisites or Prescriptive Checklist.

4 4 EPA Objectives for MFHR Program Performance less than predicted in the Proposed Design model: –Take corrective action to bring the building component to match the assumptions in the Proposed Design, or –Allow the component to remain as is, but the As-Built energy model must be adjusted to accurately represent this condition and must still demonstrate at least a 15% improvement above the Baseline Building, or –Forfeit ENERGY STAR. Performance less than level required in Prescriptive Path: –Take corrective action to remedy the problem and bring the building component to the efficiency levels required in the Prescriptive Path, or –Allow the component to remain in its current condition, but an As-Built energy model must be created to accurately represent at least a 15% improvement above the Baseline Building Design, or –Forfeit ENERGY STAR.

5 Plan Review/Inspection Work Flow Early in the design, the design team incorporates Prerequisites and requirements of the Performance or Prescriptive Path into the design. When the construction documents are 75% complete, a full plan review using the T&V Worksheets should be conducted and, if needed, corrective actions taken to ensure the program requirements are represented in the documents. Often a design team meeting with the Architect and Engineer present is needed to clarify program requirements and ensure CDs are revised correctly before they go out to bid. A second plan review at 100% CDs ensures that the program requirements are represented in the final plans. T&V Worksheets are signed and submitted to the EPA for approval, which document the final plan review and includes the Prerequisites Checklist. At or prior to the first inspection, the licensed professional in charge of submissions should schedule a kick off meeting with the GC, Architect and other key members of the project team to identify inspections and clarify expectations. The party responsible for following the MFHR Testing and Verification Protocols, must stay in contact with the GC/Architect to review applicable submittals and visit the site as necessary to conduct the required inspections. If needed, the project team must be notified of corrective actions to be taken to ensure the program requirements are being met. Applicable corrections must be re- inspected to verify and document compliance. Post construction and inspection, the T&V worksheets are updated to reflect the As-Built building and the Photo Template is completed. The As-Built model for the Performance Path must reflect any changes found during T&V. The designated licensed professional re-submits the Testing and Verification Worksheets to the EPA for approval. This includes the Prerequisite Checklist or Prescriptive Checklist and results of T&V. Photo template is also submitted. Building may be labeled as ENERGY STAR Design Construction Post Construction

11 Performance Specification Criteria Actions to be taken to ensure that appropriate language is included in bid and contract documents so that the building meets program requirements and contractors are aware of expectations. 11

12 Performance Specification Criteria: Contract Language For example: Allow inspection of all energy related components. Provide submittals for review and report installation dates immediately. Ensure the ENERGY STAR label remains attached to products and appliances when applicable. 12

13 Procedure and Documentation Steps to be followed to ensure that each building element is inspected at the appropriate time, that the necessary data is documented in the T&V Worksheets and, if applicable, used in the As-Built energy model or to prove that requirements of the Prescriptive Path have been met. 13

14 Schedule Identifies the point in construction when a particular inspection or test should take place. 14

15 Responsible Parties Identifies the parties responsible for a specific inspection or test and which other parties need to be available or coordinated with to effectively carry out the inspection. 15

16 Sampling Requirements For building components that are duplicated many times throughout the building (e.g., windows, light fixtures) or cover large areas or sections of the building (e.g., wall insulation), the specific protocol identifies the minimum required area or sample to be inspected. 16

17 Sampling Requirements: RESNET Refer to RESNETs 2006 Mortgage Industry National Home Energy Rating Systems Standards, Chapter 6 for the full description of RESNETs sampling protocols; however, the intent is captured in the following sections: A complete set of Sampling Controls shall be performed at a minimum ratio of one (1) test or inspection out of seven (7) spaces/apartments within a given sample set… …the sampling controls may be completed collectively on a single space/apartment or distribute the tests and inspections across several spaces/apartments within a given sample set, provided the total number of individual tests and inspections meets or exceeds the minimum ratio set forth in

18 Sampling Requirements: RESNET To qualify for sampling in a metropolitan area, a builder shall first complete, without any incidence of failure, a complete set of sampling controls on at least seven (7) consecutive apartments in that metropolitan area. For this initial phase of testing and inspections, the complete set of sampling controls shall be performed on each of the seven (7) apartments When an initial failure occurs, the failed item(s) shall be tested or inspected in two (2) additional spaces/apartments selected from the same sample set. Testing and/or inspections for any item(s) that may become inaccessible during the construction process, (e.g., wall insulation) must be timed so additional testing and/or inspections can occur on other spaces/apartments in the sample set before they become inaccessible for inspection or testing. 18

19 Sampling Requirements: RESNET When an additional failure occurs, in one or more of the two (2) additional spaces/apartments, the failed item(s) shall be tested or inspected in the remaining four (4) spaces/apartments selected for the same sample set Until the failure is corrected in all identified (failed) spaces/apartments in the sample set, none of the spaces/apartments shall be deemed to meet the threshold or labeling criteria Action is required if three (3) additional failures occur within a ninety (90) calendar day period. The required action depends on whether those additional failures apply to the same failed item or various failed items. 19

51 Photo Template This Word-based template was designed so that pictures used to provide photo-documentation required by the T&V Protocols could be easily formatted and consistently reported. Photo documentation must be submitted to the EPA or its designated agent at the end of construction The Photo Template need only be submitted for the Developers first three buildings that participate in the Program. Also, if the licensed professional validating documents has successfully submitted at least three Photo Templates, the requirement is waived. 51

52 Testing and Verification Worksheets Mandatory Excel-based worksheets that document the results of plan reviews, inspections, verification, and performance testing. –Provide inspection worksheets that can be used in the field that follow the Testing and Verification Protocols, but are organized for the convenience of the site inspector. –Provide a central file to store building information relevant to all members of the design team: architect, energy modeler, site inspector, project manager, plan reviewer, etc. –Must be submitted once prior to construction to document results of the plan review and once after construction is complete, to document the results of testing and verification. Webinar available online to demonstrate this tool. 52

53 Tips for Success

54 Tips for Success # Understand all requirements and T&V protocols before design is complete! 2.Ensure all energy-related details are included in the bid documents. 3.Use pre-bid meetings to help answer questions and clarify expectations. 54

55 Tips for Success # Identify responsibilities. 5.Attend pre-construction meetings and call out commonly overlooked details. 6.Stay informed of construction schedule! 55

56 Tips for Success # Dont select sample set ahead of time! 8.…except when unique details need to be inspected before installed building wide. 9. Mock-ups are your friends. 10.The T&V Worksheets and Photo Template are also your friends! 56
