Die Publikation Hacking the Porcelain Industry dokumentiert ein experimentelles Designprojekt, das sich mit den gestalterischen Potenzialen von Porzellan im industriellen Kontext auseinandersetzt. In Kooperation mit der KOBER Steinwiesen GmbH & Co. KG entwickelten Studierende des Studiengangs Integriertes Produktdesign an der Hochschule Coburg visionäre Konzepte und experimentierten mit innovativen Fertigungstechniken. Der Fokus lag auf einer ergebnisoffenen, forschenden Gestaltungspraxis, die traditionelle und digitale Prozesse – darunter den 3D-Druck – neu interpretiert.

Die Publikation gibt Einblicke in die kreativen Arbeitsprozesse, die entstandenen Designobjekte sowie Strategien zur Vermittlung der Ergebnisse. Ergänzt wird sie durch das Beilagenheft Porcelain Prints, das sich speziell den gestalterischen und technischen Möglichkeiten des 3D-Drucks mit Porzellan widmet – einem Feld mit großem Zukunftspotenzial. Die Veröffentlichung zeigt, wie durch interdisziplinäre Zusammenarbeit zwischen Hochschule und Industrie innovative Perspektiven für ein traditionsreiches Material entstehen.

This study investigates the social acceptance of integrated photovoltaic (IPV) systems in heritage and landscape contexts, focusing on Italian stakeholders in the construction sector. As part of the “BIPV meets History” research project, this study aims to identify barriers, potentials, drivers, and challenges for widespread PV technology adoption, considering heritage conservation, land preservation, energy production, and climate mitigation. A survey exploring opinions on PV technology integration was conducted. The survey was improved and extended to a total of 271 respondents, using the online method of Computer-Aided Web Interviewing (CAWI), to understand how perceptions of integrated photovoltaics have changed after COVID-19 and the European energy crisis, emphasizing aesthetic, environmental, economic, and personal aspects. The results indicate a general awareness of the technologies, with increasing acceptance in protected contexts, for historic buildings (from 51 to 68%) and especially landscapes (from 44 to 71%), driven by energy and environmental benefits. Cultural concerns, particularly the risk of impacting historical and natural identities, emerge as major barriers. Additionally, it is evident that awareness of PV panel recycling methods is still limited.

Wie kann man virtuell, ohne Körper, ohne Hände, eine Schublade öffnen?

Die erfolgreiche Kooperation von Prof. Dr. Michael Markert mit der Klassik Stiftung Weimar wurde auch in diesem Jahr fortgesetzt: In einem Pilotprojekt der Klassik Stiftung Weimar wurde Johann Wolfgang von Goethes Studier- und Arbeitszimmer von Digitus.Art hochauflösend im digitalen Raum nachgebildet. Mit dem über Neustart Kultur geförderten Projekt, können sich Besucher vom virtuellen Zimmer in Goethes Wohnhaus einen hyper-realistischen Eindruck des Raumes in einer immersiven Installation auf einer Bildschirmwand machen. Das eigentliche Zimmer im Museum darf ansonsten nur betrachtet, aber nicht betreten werden. Bislang stand vor allem die Rekonstruktion und Nachbildung des digitalen Zwillings von Goethes Arbeitszimmer im Mittelpunkt.

The abandonment and deterioration of historic rural buildings in Europe raise significant issues, including hydrogeological risks, the loss of productive land, and cultural heritage decline. Despite being underestimated, these structures hold significant potential for cultural and productive activities. Renovating these structures is crucial for local communities committed to preserving their heritage, and it is a more sustainable approach than constructing new buildings. This study explores activities undertaken in the Interreg IT/AT project “SHELTER” in Valbrenta (IT): through a participatory approach involving communities, stakeholders, designers, and researchers, an energy concept is developed for refurbishing an abandoned tobacco farm, chosen by the community, to be an alpine hut. Due to the inability to connect to the city electricity grid, the new energy concept focuses on minimizing consumption through envelope refurbishment, efficient heating, and domestic hot water systems. Additionally, the integration of renewable energy sources, particularly Building Integrated Photovoltaics (BIPV), is emphasized to preserve the building’s original appearance. This study demonstrates the feasibility of meeting seasonal energy needs entirely through renewables and explores the potential integration of biomass for meeting annual energy requirements.

The challenge of transforming historic buildings and city centers into energy-self-sufficient environments requires innovative solutions. The research project “BiPV meets History” addressed this challenge by providing comprehensive guidelines for assessing the integration of photovoltaic (PV) systems in protected historic architectural contexts. To validate these guidelines, this study conducts a thorough examination of best practices through the mentioned guidelines, developing an application tool. Recognizing the power of well-communicated best practices in overcoming obstacles to integrated photovoltaic adoption, this tool is used to assess PV integration quality with respect to the best practice contained in the HiBERatlas database. The analysis of 17 successful refurbishment cases highlighted the robustness and reliability of the proposed methodology, considering aesthetic, technical, and energy aspects. This study emphasizes the potential of the guidelines for achieving a harmonious integration of renewable energy solutions with historic architectural heritage and landscape and improving usability through the developed tool.

This study presents an in-depth analysis of 69 case studies focusing on the energy retrofit of historic buildings, uncovering challenges, best practices, and lessons learned to balance energy efficiency improvements with heritage preservation. The findings highlight several challenges encountered during renovations, such as complex heritage evaluations, restrictions on alterations, coordination issues with authorities, technical limitations, higher investment costs, and knowledge gaps. On the other hand, identifying factors promoting renovation, including demonstrating energy savings while respecting heritage, early collaboration between planners and authorities, and quantifying investments, could incentivize owners and authorities. The limitations of a still-limited sample size, occasional incomplete data, and potential sample bias call for cautious interpretation of the presented analysis. Despite these, the study provides valuable insights into successful projects, emphasizing the need for scalability, knowledge transfer from innovative policies, and targeted policy-making for successful replication. The study concludes with a call for further development of the HiBERatlas (Historic Building Energy Retrofit atlas), an extensive resource for historic building renovation, expanding its database, collaborating with agencies, and tailoring guidance for stakeholders to foster energy retrofits in heritage buildings.

This study explores the influence of uncertain boundary climate conditions on the hygrothermal performance of an internally insulated historic masonry wall using numerical simulations. The research compares diverse internal and external climate data sources to evaluate their reliability. A pre-validated hygrothermal simulation model serves as the benchmark for comparing simulated data with actual monitoring data. An array of climate data sources, including adaptive indoor climate models defined in the EN 15026 and UNI EN ISO 13788 standards, Typical Meteorological Years, and ground weather station data are considered. The core assessment parameters are temperature and relative humidity values beneath the insulation. Unexpectedly, the findings reveal that external climate conditions have a minor influence on the simulation results. Conversely, internal climate conditions significantly impact the outcomes, causing substantial variations. These implications underline the criticality of selecting an appropriate indoor climate model and moisture load class. The incorrect choice can lead to substantial errors, with peak relative humidity values predicted by the models varying in a range greater than 15 percentage points of relative humidity. In conclusion, the study reveals that utilizing Typical Meteorological Years and adaptive indoor climate models still yields excellent results, despite the inherent uncertainties. Moreover, this study emphasizes the importance of carefully selecting suitable indoor climate models to enhance the accuracy of hygrothermal simulations in historic buildings and underlines the need for future research focused on developing more precise guidelines for identifying the correct moisture load classes.

Farbige Photovoltaik mit und ohne strukturierte Oberflächen bietet ganz neue Möglichkeiten der Integration in Situationen, in denen man anderenfalls aus gestalterischen oder anderen Gründen davon absehen würde.
Ein Beispiel? Stilfs hat als Dorf eine sehr differenzierte Dachlandschaft – und dank seiner Steilheit sind die Dächer gut erreichbar für die temporäre Einrichtung von Photovoltaik-Musterflächen und gut sichtbar für die
Betrachter – DIE Gelegenheit also, um am realen Beispiel zu sehen, wie innovative Photovoltaik wirkt.

Deshalb sind wir mit dem Kurs "Neu trifft auf Alt" am Samstag, den 16. September 2023 beim Streumarktes in Stilfs zu Gast. Er richtet sich insbesondere an Architekten, Ingenieure und Fachinstallateure, die mehr über die
Integration von Photovoltaik im historischen Kontext erfahren möchten.

An die Einführung und Vermittlung des nötigen Know-Hows zum Einsatz farbiger Photovoltaik, schließt eine Dorfrunde an, bei der wir an unterschiedlichen Dächern mögliche Umsetzungsvarianten sehen und diskutieren
können. Mit dabei ist auch die Landeskonservatorin Dr. Karin Dalla Torre.
