The proposed approach is explored based on a case study of a student dormitory in need of renovation in the urban area of Munich. Based on theoretical knowledge and design experimentations that link the fields of architecture, climate-responsive design, terrestrial ecology, and digital fabrication, a set of design principles for the additive manufacturing of inhabitable ceramic tiles is conceived and transferred into a computational design tool. The conception of single tiles and the overall façade design are developed in terms of their positive climatic impact on both the animal species and humans, their nesting opportunities, their structural feasibility, and their integrability with standard ceramic façade systems. To verify the fabricability of the proposed design, a façade fragment was additively manufactured as a prototype in 1:1 scale. The initial findings presented in this paper provide a glimpse of how emerging digital technologies could provide new ways to expand current habitual architectural planning and fabrication tools, to enable the creation of site-specific solutions, and to bring together human and animal needs.","PeriodicalId":37451,"journal":{"name":"Journal of Facade Design and Engineering","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-12-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45901686","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Moreover, its flexibility provides great design freedom and its transparency makes it very suitable for façade applications, maintaining views to the outside while providing solar shading. Suntex is a solar textile, currently in development, intended for textile architecture applications like textile façades. By combining three qualities, namely providing the building with energy generation, solar shading and a unique aesthetic appearance, which also promotes the acceptance of solar technology, it offers a positive climate impact. \u0000Suntex can be considered as a new type of membrane material for Building Integrated Photovoltaics (BIPV). With this innovative, constructive fabric, enormous surfaces that are still unused can be outfitted with energy-generating potential. \u0000This paper presents a design case to analyse the potential impact of Suntex as a textile façade.

Even at objects protected as listed heritage, renovation usually results in a high degree of material exchange and replacement. This is especially the case in regard to historic curtain wall constructions. Based on the case study of the Commerzbank High-rise and original planning documents by Gartner, the paper focuses on the applied strategy of disassembling and reassembling the curtained aluminium sandwich elements, and the resulting upgrading of the original façade with a newly installed interlayer for insulation. The paper discusses the possible transfer of this strategy, which largely depended on the existing high quality of the aluminium components, their corrosion-resistant properties and low weight. The case study of the former Commerzbank High-rise indicates that a long-term preservation of post-war modern building stock can be achieved without wholesale replacement of original building components.

Additionally, avoiding glue parts can enhance the sustainability of the façade as its elements can be replaced (extending the durability of façades and therefore buildings) and separated once that they reach their end of life (to re-use or recycle them). Thus, the connection between materials might have a considerable impact on the façade’s sustainability. Moreover, timber-based façades can have different claddings, impacting on the water needed for the technology and their Global Warming Potential (GWP). This paper assesses, through a novel methodological approach, materials’ reusability, water use, and GWP for different façade connections and claddings. Four prototypes with different connections (staples, screws, timber nails, and geometrical assembly) were built. Experimental activities representing façade elements’ substitution and disassembly provided qualitative and quantitative information about production, extraordinary maintenance, and end-of-life phases. Through these tests, the quantity of material that could be re-used and disposed in such phases was quantified and then inserted in a Life Cycle Analysis (LCA). LCA was conducted using EF v.3.0 impact method and components were modelled with EPD information and Ecoinvent cut-off 3.7 database. According to the results, a timber-based façade with timber nails and wood cladding is the most promising of reusable façade materials, decreasing the water use and GWP.","PeriodicalId":37451,"journal":{"name":"Journal of Facade Design and Engineering","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-12-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49505807","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, those studies barely cover its collateral Embodied Energy (EE). As the Circular Economy is gaining momentum and the balance between OE and EE is shifting, the Life Cycle Energy Performance (LCEP) is becoming increasingly relevant as an indicator. LCEP accounts for all the OE and EE a building consumes during its lifespan. However, clear insights into the LCEP are still to be investigated. This study focuses on developing a circular and energy-efficient renovation solution for a common terraced dwelling typology in the Netherlands. The energy-efficient renovation is based on three circular strategies: Biomimicry, Urban Mining, and Design for Disassembly (DfD), covering the aspects of EE and future reuse of building materials and components. The developed renovation solution reduces 82% of the LCEP compared to the existing scenario. With additional photovoltaic (PV) modules, the dwelling reduces 100% of the LCEP. Applying biomimicry, urban mining, and DfD-based renovation can significantly lower the overall LCEP and its collateral environmental impacts to achieve a Life Cycle Zero Energy circular renovation.","PeriodicalId":37451,"journal":{"name":"Journal of Facade Design and Engineering","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49478357","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study focuses on finding adequate fibre and laminate arrangements for bistable laminates used in functional kinetic shadings. We present a study with a mixed-methods approach, combining experimental prototyping and performance simulation studies. We fabricated and analysed the geometry of a series of prototypes, conducting daylight studies to assess the performance of different laminates and fibre arrangements and showing how specific fibre arrangements can help control daylight throughout the day. We concluded that controlling fibre arrangements of bistable laminates could increase the functionality of bistable kinetic shadings in terms of daylight control, leading to more differentiated shapes between their two stable states, which corresponds to the open and closed positions of the shadings. Increasing such a difference increases the range of system configurations and, therefore, the ability to respond to various external lighting conditions and internal user requirements.","PeriodicalId":37451,"journal":{"name":"Journal of Facade Design and Engineering","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-11-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45740093","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As one of the significant developments in the façade industry over the last decade, the adaptive façade offers an intelligent solution that can decrease energy consumption and potentially increase users’ comfort in a building. From an engineering perspective, these advanced technologies aim to improve the overall performance of the building while generating a better indoor environment for the users, but unfortunately, investigations show that this goal is not always achieved. This is why, to bridge this performance gap, we embark on a change of perspective in façade design, from a technology-centred to a human-centred one. This research emphasizes that, with their changeability aspects, adaptive façade technologies offer unique potential, although the design of such façades requires a deeper understanding of users. With this as its focus, this paper aims to identify the factors affecting the user experience in a working environment, considering the interactions of the user with building services and façade systems from a holistic point of view, in which façade-user relationships are to be distinguished, towards the larger aim of developing a human-centred approach for adaptive façade design. \u0000","PeriodicalId":37451,"journal":{"name":"Journal of Facade Design and Engineering","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-06-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42923412","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
