SNARF for: New Standard: Test Method of Wind Uplift Resistance for Roof-Top Building Integrated Photovoltaics (BIPV)

Originating Global Technical Committee: Photovoltaic
Originating TC Chapter: China
Task Force (TF) in which work is to be carried out: Building Integrated Photovoltaic (BIPV) Task Force
Note: If a new task force is needed, also submit a task force organization form (TFOF)

1. Rationale:
a. Describe the need or problem addressed by this activity.
(Indicate the customer, what benefits they will receive, and if possible, quantify the impact on the return on investment [ROI] if the Document is implemented.)
According to the domestic marketing data provided by the China Academy of Building Research, the total roof area of existing industrial and commercial buildings (including public buildings) that can be installed for photovoltaics is about 6 billion square meters, and the facade is about 1.6 billion square meters, totaling nearly 8 billion square meters. Assuming that BIPV is built in all the areas, a total of 1,100 GW will be achieved, equivalent to a potential market of 5.5 trillion RMB Yuan. In the market, most of the wind uplift resistance tests on structural safety currently follow international standards, e.g., FM4474, AS4040, ASTM E 1646, or domestic standards such as GB/T31543, JGJ255, GB50896. It is difficult for experimental institutions to understand the design idea of intergrated photovoltaic modules to form products and BIPV waterproof and drainage. The judgment basis might not be suitable for the structural characteristics of BIPV products, and the electrical safety and technical requirements of use functions of photovoltaic products are not taken into consideration (e.g., wet leakage, power attenuation), resulting in that the experimental results are not inconsistent with actual requirements. The Photovoltaic industry standards IEC61215 and IEC61730 also have no requirements for wind uplift resistance performance testing of BIPV products. The wind uplift resistance performance is related to the safety of the building structure. Without reasonable experimental results, the products will not be accepted by owners and cannot be covered by all insurance companies. This standard sets up a project in response to the above-mentioned industry issues and forms a wind uplift resistance test standard for metal roofing integrated photovoltaic (BIPV) products.

b. Estimate effect on industry.
1: Major effect on entire industry or on multiple important industry sectors - identify the relevant sectors
Sector or Company Information: PV

c. Estimate technical difficulty of the activity.
II: Some Difficulty - Disagreements on known requirements exist but developing consensus is possible

2. Scope:
a: Describe the technical areas to be covered or addressed by this Document development activity. For Subordinate Standards, list common concepts or criteria that the Subordinate Standard inherits from the Primary Standard, as well as differences from the Primary Standard:
1. This standard is applicable to the wind uplift resistance test on BIPV for roof-top of commercial and industrial buildings(be not applicable to skylight).

2. This standard covers test method on such performance as static wind uplift resistance, dynamic wind uplift resistance and water penetration resistance.

b: Expected result of activity
New Standard or Safety Guideline (including replacement of an existing Standard or Safety Guideline)

b. List any planned Type I Liaisons with external nonprofit organizations (e.g., SDO) that should receive Draft Documents from Standards staff for feedback during this activity and be notified when the Letter Ballot is issued (refer to Procedure Manual 7):

c. Intercommittee Ballots:
will not be issued

Identify the recipient global technical committee(s):

5. Safety Considerations:
The resulting document is expected:
NOT to be a Safety Guideline

NOTE FOR "to be a Safety Guideline": When all safety-related information is removed from the Document, the Document is NOT technically sound and complete - Refer to Section 15.1 of the Regulations for special procedures to be followed.

NOTE FOR "NOT to be a Safety Guideline": When all safety-related information is removed from the Document, the Document is still technically sound and complete.

6. Intellectual Property Considerations:
a. For a new Standard or Safety Guideline and for any part to be modified or added in a Revision of published Standards and Safety Guidelines:
the use of patented technology is NOT required.

If "patented technology is intended to be included in the proposed Standard(s) or Safety Guideline(s) " is selected above, then also check one:

b. For Revision, Reapproval, Reinstatement, or Withdrawal of existing Standard(s) and Safety Guideline(s):

c. The body of the Document and any Appendices, Complementary Files, Related Information sections, or Various Materials that may or may not be a part of the Document by reference:
the incorporation of Copyrighted Item will NOT be required

NOTE FORthe use of patented technology or the incorporation of Copyrighted Item(s) is NOT required’: If in the course of developing the Document, it is determined that the use of patented technology or Copyrighted Item(s) is necessary for the Document, the provisions of Regulations 16 must be followed.
