Task 15 Managers:Helen Rose Wilson, Fraunhofer ISE, GermanyFrancesco Frontini, SUPSI, Switzerland Multi-DimensionalEvaluation of BIPV Building Integrated Photovoltaics(BIPV) represent a pivotaltechnology in sustainable building The multi-dimensional evaluation methodologyfor BIPV installations is designed to facilitate Development of the Multi-Dimensional Evaluation Tool Establishing clear research objectives and defining variables and parameters across four main categories of Development of a numerical rating system for each PI to enable a comparative quantitative and qualitativeanalysis of different BIPV installations according to several indicators per category. For the visual PIs, a semi- The aim of the comparativeassessment of the multi-dimensional performance is tolearn from existing BIPV Development of a harmonized classification scheme for BIPV installation types. This scheme is an optimized Application of the Multi-Dimensional Evaluation Tool Selecting diverse BIPV installationsrepresenting different building typologies (e.g., facades, roofs,external devices). Each installation serves as a case study for comparative analysis. The evaluation can planned projects and is then based on data from data sheets, tabulated environmental data,simulations and renderings; Applying the multi-dimensional methodologyto quantify and rate each installation's performanceacross defined PIs. This involves data collection, analysis, and interpretation using standardized Case Studies Apartment Building Retrofit with Colored BIPV Modules (Switzerland) Retrofit of an apartment building integrating colored photovoltaic modules on facades(leading to a performance loss of around 35 %).The complex building design results in severe shading conditions. Office Building with Integrated BIPV Facades and Roofs (Uppsala, Sweden) LEED Platinum certified office building with BIPV on facades and roofs, necessitatingthe implementation of highly effective energy systems and innovative solutions.Built with a full timber frame and designed for high energy-relevant performance to Terrace Houses with Standardized BIPV Roofs (Delft, the Netherlands) Exasun uses prefabricated, standardized products to replace traditional roof tiles.The X-Roof system seamlessly integrates with dormer windows, skylights, and roof Foto:ExasunJan-Jaap van Os;https://exasun.com/ Retrofit of Apartment Building with BIPV Window Balustrades (Northern Italy) BIPV Parapets: Installed as part of the retrofit using a versatile click-&-Go substructuredeveloped in the EnergyMatching R&D project (Horizon 2020).BIPV Window Balustrades: Developed within a "Solar Window Block" system, which isprefabricated and multi-functional. It includes a BIPV system integrated with a battery Challenges and Considerations The evaluation tool faces several challenges: Data Availability:Limited availability and authorization for data usage can hinder comprehensive Standardization Issues:The lack of standardized definitions for determining each PI can lead tosignificant problems when comparing the performance of different BIPV applications, e.g. when Environmental Data Variability:Different methods of data generation for environmental data can Subjective Aesthetic Assessment:Visual performance assessments are inherently subjective, Outlook The tool was initially designed for across-sectional comparisonof different BIPV installations. However, Assessing competing options for a specific project in the planning phase:External boundaryconditions are fixed (location, construction, operation time), economic conditions (interest rate, capital Seperate evaluation of of each performance indicator:This can be useful for potential BIPV Analysing pioneering installations (like Case Study 1): This helps determine achievements, identify A longitudinal analysisof a BIPV installation over its lifetime is planned in Phase 3 of Task 15. Ongoing research will explore long-term performance impacts and evolutionary trends of This methodology represents a significant advancement in evaluating BIPV systems,fostering effective and sustainable integration of photovoltaics in various architectural IEA PVPS Task 15 Task 15 aims to establish a framework to accelerate the global adoption of BIPV products in renewableenergy and construction sectors, ensuring fair competition with BAPV and traditional building components. Itintegrates BIPV into both electric and construction technologies, emphasizing value-added contributions to This Fact Sheet is based on an article from IEA PVPS Task 15 experts, which has been published inEnergy Wilson, H.
