This section defines the functional and technical requirements for the use of electronic and digital signatures in the registration of compliance documents. These specifications shall be implemented by a Data Registry as a condition of approval of the Data Registry by the Commission.
JA7.6.2.1 Interfaces - Main Users
(a) Authorized Users of Data Registries who must sign Compliance Documents either as the Documentation Author, or Field Technician, or as the Registration Signer (responsible person).
(b) Registration Providers who must implement the electronic and digital signature specifications into the Data Registry user interface to provide Electronic Signature capabilities to the Authorized Users of the Data Registry, and must append their digital signature to all registered compliance documents created in their Data Registry.
(c) Commission Compliance Document Repository which must receive registered documents transmitted from the Data Registries and will process the digital signature to validate the sender and the contents.
(d) Persons or Software Entities who Validate Electronic Documents who may receive electronic copies of registered documents made available by the Data Registries and will process the digital signature to validate the sender and the contents.
(e) Compliance Software Tools that export compliance documents for transmittal to the Data Registries that must subsequently be electronically signed and registered in the Data Registry.
JA7.6.2.2 Major Functions
The electronic and digital signature requirements of the Data Registry consist of the following major functions:
The Data Registry shall provide electronic signature capability to authorized users.
The Data Registry shall check that compliance documents are complete and the data entered meets the data validation rules for the applicable document before making the documents available for signing or registering.
The Data Registry shall provide functionality for authorized users to select, review, and sign compliance documents as a Documentation Author, Field Technician, or Registration Signer.
The Data Registry shall apply the Registration Provider's Digital Signature to compliance documents electronically signed by the registration signer when concluding the document registration procedure in the Data Registry, and then append the Registration Provider's digital certificate issued by a certificate authority approved by the California Secretary of State.
The function of the Registration Provider's digital certificate is to provide verification from an approved certificate authority that the document came from the Registration Provider's Data Registry and to provide automated document verification to persons or agencies that receive electronic submittals of these registered documents.
The Data Registry, upon completion of the registration procedure, shall immediately and automatically transmit a copy of the completed registered compliance document to the Commission Compliance Document Repository which will process the Registration Provider's digital certificate to validate the sender and the compliance document contents.
The Data Registry shall retain a copy of the completed registered electronic compliance document and make the document available for use by authorized users of the registry who may access a copy of the registered document and may subsequently process the Registration Provider's digital certificate to verify the sender and the compliance document contents.
The Data Registry shall process the completed Compliance Registration Package from Compliance software tools or other software tools approved by the Commission for use in the Compliance Document Registration process.
JA7.6.2.3 User Characteristics
There are four categories of users who will participate in the electronic and digital signature functionality:
This is a heterogeneous category composed of HERS Raters, building designers, building contractors, installation contractors, energy consultants, home owners, and others.
This category consists of each approved Registration Provider.
These users will need to apply decryption processing using the digital certificate to identify the sender and verify the contents of the received document. The Commission Compliance Document Repository is a main user in this category. Also, users who take advantage of digital signature automated verification capabilities to verify the authenticity of registered compliance documents received as electronic submittals from various other participants in the compliance documentation process will be another main user in this category.
Title 24 compliance software tools are the main users in this Category. The electronic compliance documents exported from the compliance tools must be formatted to provide location coordinate information for use when applying the visible aspects of electronic and digital signatures to the compliance documents. The Data Registry must be capable of appending the visible aspects of electronic and digital signatures to the correct locations in the signature blocks on the imported compliance documents during the subsequent electronic signature and registration procedures.
Detailed guidance for electronic and digital signature target coordinate information may be described in the 2013 Alternative Calculation Method (ACM) Reference 'Manual to assist in the implementation of the requirements by compliance software vendors. The Data Registry shall implement the capability to append the visible aspects of electronic and digital signatures to the signature blocks on compliance documents in these locations.
JA7.6.2.4 Constraints
The electronic and digital signature capabilities shall be implemented at least six months before the effective date for the 2013 Standards.
