Building Integrated Photovoltaic and Leasing Facades: Exploring financial and technical conditions for BIPV technologies integration into a Product Service Leasing façade system

Compliance with energy zero buildings is forcing the buildings to transform into energetic plants, which combined with the need for a circular resource conscious economy, seeks for revised forms of a technical energy efficient façade and innovative business models. Due to this, BIPV technologies implementation in the façade are studied under the frame of a leasing business scheme. In this report, BIPV technology is briefly reviewed together with architectural implementation applications and market available products. Following, BIPV financial aspects such as cost and price are examined. Also, product service systems are presented as an alternative to product oriented systems, which potentially support the framework of a circular economy. Central in the report, is the understanding and definition of value and what constitutes added value in the façade. Stakeholders roles are mapped and their “fears and hopes” drafted. Cash purchase, loan and capital and operational leasing financial archetypes are presented. Subsequent sections define different façade design scenarios, which are studied as test cases for applicability to an existing building within the TU Delft campus. Sixteen façade scenarios are proposed. Four of the scenarios are selected for further study. A methodology that follows, the cost estimating of the façade construction and the financial analysis of the cost under the different financial archetypes, generates information that allows analysis and identification of the market environment —for the demand and supply side stakeholders. To conclude a sensitivity analysis is carried out over one of the façade scenarios, allowing for definition of what business model criteria will motivates the stakeholders implementation of BIPV under a leasing façade system.Architecture and The Built EnvironmentArchitectural Engineering + Technolog
