IEA PVPS Task 15: Builiding integrated Photovoltaic (Working period 2019 - 2023)

In Subtask A, a guideline for analyzing technological innovation systems (TIS) for building-integrated photovoltaics (BIPV) was developed and applied in several countries. Insights were exchanged, developments reviewed, and conclusions drawn for both international and national contexts. Successful projects should be publicized to spread knowledge about BIPV. There is a need to harmonize PV standards and building regulations, with integrated PV being embedded in these regulations. A law requiring the dual use of sealed surfaces with (BI)PV is recommended. The BIPV market development in Austria shows potential for improvement, particularly in technical standards like fire safety and legal obligations for renewable energy in building regulations.

BIPV installations not only fulfill structural and aesthetic functions but also generate electricity. To make the multifunctional performance of BIPV projects comparable, indicators for structural, electrical, ecological, and economic assessments were defined in Subtask B. A comprehensive evaluation matrix was developed and validated by experts, based on four exemplary projects.

A major obstacle to the use of BIPV technologies in the construction industry is the lack of practical know-how and available standards for planning and implementation. Subtask C developed a BIPV guideline, which consolidates knowledge for architects, engineers, and consultants, and provides practical, interdisciplinary information to promote the integration of BIPV in the built environment. The entire process, from design and installation to operation, maintenance, and safety, is covered.
Subtask D developed digital models of BIPV elements, design guidelines, and tools. A workshop on PV digitization was organized, and exchanges with international standardization cooperations were promoted. The aim was to network with national and international stakeholders to integrate BIPV early into the digital construction planning process. A report on current BIPV digitization processes was published. Comprehensive consideration of BIPV in the urban context could provide planners and end-users with valuable insights into the feasibility of BIPV applications.

Subtask E focused on pre-normative activities, including testing methods for semi-transparent BIPV elements, outdoor tests, fire safety, BIPV safety, and standardized procedures for yield forecasting. Several reports were published, with contributions from Austrian partners. This contributed to the report on advancing BIPV standardization. Additionally, the Austrian partners are actively involved in international standardization work, particularly in the JWG 11 working group, which harmonizes standards between electrical and building regulations.
