Work Package 2: Technical integration of photovoltaics in buildings.

wp2_illustr

The following European standard for building integrated photovoltaics was published in English and French on 18 Jan, 2016: EN 50583 "Photovoltaics in Buildings" (Part 1: BIPV modules, Part 2: BIPV systems). The standard Part 1 is available in Norway as NEK EN 50583-1:2016.

In EN 50583:2016-Part 1, BIPV modules are considered to be building-integrated if the PV modules form a construction product providing a function as defined in the Construction Product Regulation CPR 305/2011. Thus, the BIPV module is a prerequisite for the integrity of the building’s functionality. If the integrated PV module is dismounted (in the case of structurally bonded modules, dismounting includes the adjacent construction product), the PV module would have to be replaced by an appropriate construction part. Mounting categories for modules that contain glass are specified as shown in the figure below, used to differentiate between additional requirements for the modules.

The European BIPV standardization work is based on existing standards in the construction sector and photovoltaic sector (see pvsites):

EN documents are developed as regional standards, intended for use in the European Union. ISO documents, released by the International Organization for Standardization (ISO), are international standards with world-wide application. The International Electrotechnical Commission (IEC) work to propose international standards for all electrically based technology, and the Norwegian IEC member is Norsk Elektroteknisk Komite (NEK). The development and synchronization of common standards applicable to all countries is also one of the activities in the IEA PVPS Task 15 collaboration. Requirements for BIPV products and systems may include:

WP2 activities:

WT 2.1: Development of robust components and solutions.
The work of this activity includes:

WT 2.2: Accelerated aging and durability testing in Nordic climate exposure.
This activity have the same focus areas as WT 2.1, and will include accelerated ageing tests for:

WT 2.3: Testing and investigating the link between aesthetic quality and PV efficiency.
Based on the results from earlier work by Klaudia Farkas (PhD 2013, NTNU) and IEA SHC Task 41, both national and international cases will be evaluated. This will provide valuable input and contributions to the other work packages.

WT 2.4: Environmental assessment and carbon footprint evaluations.
The following analysis will be performed:
