This section describes the documentation (compliance form) recommended for compliance with the requirements of the 2013 Standards with regard to electrical power distribution systems.
Documents for compliance with the 2013 requirements are proposed to change as follows:
A. For the period of January 1 through December 31, 2014, compliance documents are proposed to be similar to the 2008 compliance documents, except they have been updated to reflect changes in the 2013 Standards.
B. Starting on January 1, 2015, the Energy Commission proposes to have developed electronic compliance documents to replace existing nonresidential paper documents.
At the time a building permit application is submitted to the enforcement agency, the applicant also submits plans and energy compliance documentation. This section describes the recommended compliance documentation (forms) for complying with the requirements of the Standards. It does not describe the details of the requirements.
This section is addressed to the person preparing construction and compliance documents, and to the enforcement agency plan checkers who are examining those documents for compliance with the Standards.
The paper prescriptive compliance documents have a limited number of rows per section for entering data. Some designs may need fewer rows, and some designs may need additional rows. If additional rows are required for a particular design, then multiple copies of that page may be used.
Following is an explanation of the 2013 nonresidential compliance documentation numbering:
NRCC Nonresidential Certificate of Compliance
NRCA Nonresidential Certificate of Acceptance
NRCI Nonresidential Certificate of Installation
ELC Electrical power distribution systems
01 The first set of compliance documents in this sequence
E Primarily used by enforcement authority
A Primarily used by acceptance tester
For electrical power distribution systems, there is only one compliance form :
•NRCC-ELC-01-E; Certificate of Compliance;.Electrical Power Distribution Systems
This document has seven pages. Each page must appear on the plans (usually near the front of the electrical drawings), and must be accompanied by a voltage drop calculation worksheet. A copy of these documents should also be submitted to the enforcement agency along with the rest of the compliance submittal at the time of building permit application.
The engineer may provide the voltage drop worksheet in whatever format is convenient to them, and is accepted by the inspector. No form has been prescribed for the voltage drop worksheet, because of the wide variety of different, valid, assumptions and unusual variations that the calculations may need to include.
With enforcement agency approval, the applicant may use alternative formats of these documents (rather than the official Energy Commission documents), provided the information is the same and in a similar format.
Project Description
•Project Name is the title of the project, as shown on the plans and known to the enforcement agency.
•Date is the date of preparation of the compliance submittal package. It should be on or after the date of the plans, and on or before the date of the building permit application.
•Project Address is the address of the project as shown on the plans and as known to the enforcement agency.
•Climate Zone is the California climate zone in which the project is located. See Reference Joint Appendix JA2 for a listing of climate zones.
•Building CFA is the total conditioned floor area of the building as defined in §100.1(b). For additions, the total conditioned floor area is the total area of the addition alone. For alterations, the total conditioned floor area refers to only to the altered floor area.
•Unconditioned Floor Area is the total floor area of unconditioned space, as defined in §100.1(b). For additions, the total unconditioned floor area refers to the addition alone. For alterations, the total unconditioned floor area refers to the altered floor area.
General Information
“Building Type” is specified because there are special requirements for high-rise residential and hotel/motel guest room occupancies. All other occupancies that fall under the Nonresidential Standards are designated “Nonresidential” including schools. It is possible for a building to include more than one building type. See §100.1(b) for the formal definitions of these occupancies. All appropriate boxes shall be checked:
•Nonresidential if the project includes nonresidential indoor lighting.
•High-Rise Residential if the project includes common areas of a high-rise residential building. Common areas are any interior areas which are not dwelling units. If this project also includes dwelling units, the residential lighting compliance documentation must also be completed and submitted.
•Hotel/Motel if the project includes common areas in a hotel or motel. Common areas of a hotel/motel include any interior areas which are not dwelling units. If the project also includes dwelling units, the low-rise residential lighting compliance documentation must also be completed and submitted.
•Schools, which includes relocatable buildings on the school site.
•Conditioned Spaces as defined in §100.1(b).
•Unconditioned Spaces as defined in §100.1(b).
“Phase of Construction “indicates the status of the building project described in the compliance documents.
•New construction should be checked for all newly constructed buildings, newly conditioned space or for new construction to existing buildings (tenant improvements).
•Addition should be checked for an addition that is not treated as a stand-alone building.
•Alteration should be checked for alterations to an existing building lighting system in accordance with §141.0(b). This includes Lighting System Alterations in accordance with §141.0(b)I(ii); and Luminaire Modifications-in-Place in accordance with §141.0(b)I(iii).Tenant improvements are usually alterations.
“Method of Compliance” indicates the method of compliance used for the project.
•Complete Building Method—see section 5.7.1 of this chapter for additional information.
•Area Category Method—see section 5.7.2 of this chapter for additional information
•Tailored Method—see section 5.7.3 of this chapter for additional information
Documentation Author’s Declaration Statement
The “documentation author” is the person who prepares a Title 24 Part 6 compliance document that must subsequently be reviewed and signed by a responsible person (see below) in order to certify compliance with Part 6. Subject to the requirements of §10-103(a)1 and §10-103(a)2, the person who prepares the Certificate of Compliance documents (documentation authors) shall sign a declaration statement on the documents they prepare to certify the information provided on the documentation is accurate and complete.
A documentation author may have additional certifications such as an Energy Analyst or a Certified Energy Plans Examiner certification number. Enter number in the EA# or CEPE# box, if applicable.
The person’s telephone number is given to facilitate response to any questions that arise.
Responsible Person’s Declaration Statement
The “responsible person” signing the Certificate of Compliance is required to be eligible under Division 3 of the Business and Professions Code to accept responsibility for the building design, to certify conformance with Part 6. If more than one person has responsibility for the building design, each person (such as an eligible lighting designer) shall sign the Certificate of Compliance document(s) applicable to that portion of the design for which the person is responsible. Alternatively, the person with chief responsibility for the building design shall prepare and sign the Certificate of Compliance document(s) for the entire building design.
The person’s telephone number is given to facilitate response to any questions that arise.
This table allows the location and rating of each electrical service to be recorded, so the inspector can check that appropriate metering is provided, according to Section 130.5(a).
Each row should contain a separate electrical service. All newly installed services must be included, whether the project is a new construction project or an alteration. Also, existing electrical services must be included if the switchboard or panel they supply has been newly installed.
Each column should be filled out as follows:
The unique description, location or designation of this electrical service
The power rating of the service, in Volt-Amps
Check this column if the meter installed on this electrical service records the instantaneous (at the time) kW demand on the service
Check this column if the meter records historical peak demand (kW)
Check this column if the meter allows the total energy consumption value (kWh) to be reset at the meter.
Check this column if the meter records the energy consumption of the service, broken down according to how much energy was used during each utility rate period (for instance, on-peak vs. off-peak).
The inspector should check either the “pass” or “fail” box depending on whether the capabilities of the meter on this service meet the requirements of Section 130.5(a), set out in the table below the service schedule..
Below the electrical service schedule, Table 130.5-A from the Standards is reproduced, for ease of reference. This table sets out which metering requirements apply, depending on the size (rating) of the service.
There are two ways to comply with the disaggregation requirement of the Standards, set out in Section 130.5(b). The first is to ensure that each feeder supplies only one type of load (subject to the additions and exceptions shown in Table 130.5-B of the Standards). The second is to provide a permanently installed load measurement system that can separately record each type of load, using current transformers. The Certificate of Compliance allows the designer to indicate which method of compliance is being used.
Whichever method of compliance is used, the degree to which each feeder or load must be disaggregated depends on the rating of the electrical service that serves it. For larger services, more disaggregation is required. These requirements are set out in Table 130.5-B of the Standards, which is reproduced in the Certificate of Compliance for ease of reference.
The table allows each switchboard, panelboard, motor control center or subpanel to be recorded on a separate row. The columns should be filled out as follows:
A. The unique description, location or designation of this switchboard, panelboards, motor control center or subpanel
B. The unique description, location or designation of the electrical service that supplies it.
C. The power rating of the service, in Volt-Amps
D. The inspector should check either the “pass” or “fail” box depending on whether the feeder to this panel supplies ONLY the type(s) of load described in the relevant cell of the table. Note that:
a. In some cases the table states that there is no disaggregation requirement for that combination of load and service rating
b. in some cases (such as with plug loads) there are additional limits on how much load or how much area may be served by a single feeder.
If, instead of disaggregated panels and feeders, a permanently installed load measurement system is installed that meets the requirements set out in the table, then the inspector should check the box in the bottom row of the table.
Because there are several valid ways to perform voltage drop calculations, depending n how much is known about the location and type of the loads that will be installed, this section of the Certificate of Compliance simply requires that the engineer attach a worksheet showing voltage drop calculations that comply with the maximum voltage drops allowed by Section 130.5(c) of Standards (2% for feeders, 3% for branch circuits, at design load).
The inspector should check either the “pass” or “fail” box, depending on whether the calculations of the worksheet adequately show that the voltage drops will be within the requirements of the Standards.
For ease of reference, the tables for typical power factor of loads, and for maximum length of typical feeders and branch circuits are shown, reproduced from this chapter of the Compliance 'Manual.
This section allows the building inspector to check off whether the controlled receptacles meet the requirements of Section 130.5(e) of the Standards.
