The resulting hybrid scheme has beneficial impacts from a structural, sustainability, and indoor environmental quality standpoint. \nThe abundant natural light, penetrating through the fully-glazed skin, is controlled by an adaptive shading system, integrated with the IGU, consisting of perforated steel sheets woven together by two-way shape-memory alloy hinges that enable the component to work like an origami, opening and folding automatically according to the exterior environmental conditions: in the summer, the unfolded geometry creates an external overhang that varies with each panel exposure and alleviates the energy demand required for cooling; in the winter, the folded shape allows for a higher solar heat gain, thus lowering the heating energy demand. Therefore, the self-adaptive skin designed allows for unobstructed views throughout the envelope, as well as for an optimized control of the light, both in terms of energy and of daylighting comfort, thus mastering a Class A metropolitan office space. \nUltimately, the proposed hybrid scheme, fostering an optimized behavior of the load bearing members and an absolute minimization of the facade elements, has led to significant improvements: 11\\% less steel, 6\\% less concrete, 35\\% less embodied energy are required, when compared to a standard high-rise construction with identical geometry and featuring steel columns around the perimeter and an aluminum curtain wall facade.", "isbn" : "978-1-882352-46-3", "bibtexKey": "oliva_orbit_2018" } , { "type" : "Publication", "id" : "https://puma.ub.uni-stuttgart.de/bibtex/2bd6ba8c02c40e1755c0f2e385eb85f53/dominikfauser", "tags" : [ "analysis","experiment","humidity","mechanical","mib","mib_ls2","myown","shape-memory" ], "intraHash" : "bd6ba8c02c40e1755c0f2e385eb85f53", "interHash" : "8eea109aceeaa760a083bf458c4c2470", "label" : "Influence of humidity on the rheology of thermoresponsive shape memory polymers", "user" : "dominikfauser", "description" : "", "date" : "2022-05-16 22:43:23", "changeDate" : "2022-07-20 08:57:43", "count" : 3, "pub-type": "article", "journal": "Journal of Materials Science", "year": "2022", "url": "https://doi.org/10.1007/s10853-022-07206-8", "author": [ "Dominik Fauser","Holger Steeb" ], "authors": [ {"first" : "Dominik", "last" : "Fauser"}, {"first" : "Holger", "last" : "Steeb"} ], "volume": "57","number": "20","pages": "9508-9524","abstract": "Shape Memory Polymers (SMPs) have the inherent ability to maintain a reversible temporary shape and restore a permanent shape under an external trigger. The class of materials has great potential to contribute to smart applications in soft robotics, aerospace, actuation and biomedicine. In these potential application domains, materials are often exposed to large fluctuations due to humidity influences. Therefore, a novel approach is developed to characterize the strongly coupled thermal, humidity and time-dependent behavior of polyurethane-based SMP. Weight gain measurements with disk samples of dimension 35$$\\,$$35 $$$$1.5 $$mm^3$$and linear expansion tests with rectangular samples of dimension 10 $$$$40 $$$$1.0 $$mm^3$$at different relative humidity are carried out to perform the isothermal and isohumid dynamic measurements in thermodynamic equilibrium. The time-temperature superposition is used to characterize and compare the viscoelastic properties at different relative humidity. Concerning effective material properties, a major finding of this investigation is the horizontal shift of the material parameter in the temperature space due to the presence of humidity. Thus, the humidity-dependent material behavior is fully described by a humidity-dependent glass transition temperature. The measured experiments provide a full description of the thermal, humidity and mechanical behavior of SMPs.", "issn" : "15734803", "refid" : "Fauser2022", "doi" : "10.1007/s10853-022-07206-8", "bibtexKey": "fauser2022influence" } , { "type" : "Publication", "id" : "https://puma.ub.uni-stuttgart.de/bibtex/2cc13008a179c12d67045edb84959d8f3/dominikfauser", "tags" : [ "Diffusion","Shape-Memory","mydata","myown" ], "intraHash" : "cc13008a179c12d67045edb84959d8f3", "interHash" : "1559250040e82ef3a697ed75d5896720", "label" : "Humidity and thermal triggered Shape Memory Effect - Rheology-based numerical modelling - Diffusion measurements", "user" : "dominikfauser", "description" : "", "date" : "2021-10-13 14:15:15", "changeDate" : "2022-07-20 09:07:48", "count" : 3, "pub-type": "article", "publisher":"DaRUS", "year": "2021", "url": "https://doi.org/10.18419/darus-2024", "author": [ "Dominik Fauser","Moritz Kuhn","Holger Steeb" ], "authors": [ {"first" : "Dominik", "last" : "Fauser"}, {"first" : "Moritz", "last" : "Kuhn"}, {"first" : "Holger", "last" : "Steeb"} ], "unf" : "UNF:6:ig+5CuLNRHaoCQtncwbvWA==", "version" : "V1", "doi" : "10.18419/darus-2024", "bibtexKey": "darus-2024_2021" } , { "type" : "Publication", "id" : "https://puma.ub.uni-stuttgart.de/bibtex/283fcef1d6c7b5a669ab58e74439c5037/dominikfauser", "tags" : [ "Polymers","Shape-Memory","Thermo-Mechanical-Cycle","mydata","myown" ], "intraHash" : "83fcef1d6c7b5a669ab58e74439c5037", "interHash" : "fcfb2c40041854618e0806ea79dc39b7", "label" : "Humidity and thermal triggered Shape Memory Effect - Rheology-based numerical modelling - Thermal Humid Mechanical Cycle", "user" : "dominikfauser", "description" : "", "date" : "2021-10-13 14:14:14", "changeDate" : "2022-07-20 09:08:14", "count" : 4, "pub-type": "article", "publisher":"DaRUS", "year": "2021", "url": "https://doi.org/10.18419/darus-2023", "author": [ "Dominik Fauser","Holger Steeb" ], "authors": [ {"first" : "Dominik", "last" : "Fauser"}, {"first" : "Holger", "last" : "Steeb"} ], "unf" : "UNF:6:kJCrJ2myXSEklpfIfr7AfQ==", "version" : "V1", "doi" : "10.18419/darus-2023", "bibtexKey": "darus-2023_2021" } ] }
