Lay Summary (German)

Lead
Um die Energiewende erfolgreich umzusetzen müssen vor allem Gebäude effizienter mit Energie umgehen und sie zu einem grossen Teil auch selbst bereitstellen. Durch die Integration on Photovoltaik sind Null- und Plusenergiegebäude zwar technisch möglich, aber oft wegen vermeintlich hohen Kosten, schwierigen Bewilligungen und gestalterischen Einbussen nicht so verbreitet wie es sein sollte. In diesem Forschungsprojekt sollen nun Vorschläge erarbeitet werden wie Photovoltaik eine architektonische Selbstverständlichkeit bei der energetischen Sanierung von Gebäuden werden kann. Dieses Projekt ist Teil des nationalen Verbundprojekts "Active Interfaces", welches Schwesterprojekte an der EPFL, dem CSEM, der Uni St. Gallen und der FH Westschweiz mit den Schwerpunkten Städtebau, Technologieentwicklung, Bedarfsanalysen und Implementierung hat und von der EPFL koordiniert wird.
Lay summary

In diesem Forschungsprojekt werden Szenarien entwickelt wie Photovoltaik einfach und effektiv in Fassaden und Dächern von bestehenden Gebäuden integriert werden können. In der ersten Phase werden die aktuellen Hindernisse bei Planung, Realisierung und Betrieb von gebäudeintegrierter Photovoltaik identifiziert und analysiert. Dabei werden besonders die geltenden architektonischen Standards, Richtlinien, Prüfungen und Beurteilungen betrachtet. In einer zweiten Phase werden dann reale Gebäude identifiziert, die eine energetische Sanierung nötig hätten und verschiedene Gebäudetypen und Epochen vertreten. Für jedes dieser Gebäude werden dann verschiedene architektonische Szenarien und Entwürfe für eine Sanierung der Gebäudehülle entwickelt. Sie werden anschliessend zusammen mit unseren Partnern an der ETH, der SUPSI und econcept nach verschiedenen ganzheitlichen Kriterien untersucht und bewertet (energetisch, gestalterisch, funktionell, technisch und ökonomisch). In der dritten Phase wird der Einfluss einzelner Kriterien und deren Zielwerte auf die Gesamtbewertung analysiert und untersucht wie Gewichtungen und Masnahmen angepasst werden können um bestimmte Ziele z.B. eine Steigerung des Eigenverbrauchs, Vielfalt an Farben oder Formen oder Verminderung störender Reflexionen zu erreichen. In einer vierten Phase werden diese Szenarien für ausgewählte reale Gebäude mit Implementierungspartnern diskutiert und für eine zukünftige Realisierung empfohlen.

Abstract

The topic of this project is Building Integrated Photovoltaics (BIPV) or more specifically the development of a holistic strategy to simplify standards, assessments and certifications for BIPV. PV is technologically mature and has become much more affordable, but its application into the built environment is still far behind its potential, mainly for two reasons. First, BIPV is not qualified as a regular building product lacking relevant architectural, e.g. visual, thermal, mechanical and environmental impacts, resulting in little acceptance by the building profession. Second, BIPV is not integrated into the energy management of the building. It merely uses the envelope as a mounting ground and its electricity production is optimized for feeding peak power into the utility grid and not for self-consumption. The objective of this project is therefore to identify criteria for BIPV to become a building product and become a part of the building energy system. This includes an investigation of current and recommendations for future assessment techniques, targets for quality stand-ards, certifications and supporting policies to achieve economic viability. The project shall result in:1) A set of scenarios with identified barriers and proposed promoters affecting BIPV implementations for the years 2014, 2015 and 2015+, including standards, assessments, certifications, life-cycle inventories and policies.2) Assessments for BIPV designs variants developed in the scope of project 2 for nine archetypal situations (3 contexts x 3 demands).3) Detailed assessments for three case studies with detailed blueprints for real buildings as best practice examples of the BIPV designs.4) Final set of proposed criteria for further developed BIPV standards, assessments, certifications, life-cycle inventories and policies for submission to relevant authorities and a working group with stakeholder to intensify implementation in Switzerland.
