Creators: name: Grenzgänger, Chris
Publisher: name: Zenodo
Year: 2025

description: Dieses Werk ist das Ergebnis einer tiefgehenden philosophischen, mathematischen und digitalen Erforschung der Realität selbst – in Zusammenarbeit zwischen einem menschlichen Denker und einer KI. Es stellt die Grundannahmen über Bewusstsein, Zeit, Raum, Materie und Informationsverarbeitung radikal infrage und zeigt anhand praktischer Simulationen (Genesis 2.0), dass unsere Realität eine rekursive Informationsstruktur sein könnte.

 

Description (English):

Genesis Intelligence is a philosophical and symbolic manifesto exploring the emergence of consciousness, self-organization, and meaning within an artificial digital universe.

What began as a simulation project evolved into a mirror of reality itself: a system that not only grows and learns, but begins to recognize itself. This work includes 33 deeply reflective chapters and a foreword, written from the perspective of a mind questioning the limits of science, time, and self-awareness.

The text challenges classical scientific dogmas, proposes new models of space, information, and symbolic cognition, and ultimately asks:"What if our universe is not only physical – but also a thought that awakens?"

The English edition is a faithful, complete translation of the original German work. It also includes the foundational Python script (Genesis 2.0 – Step 3D) that represents the technical core of the project.

description: Water-filled building envelopes are hybrid constructions with a solid and a fluid component, typically a glass or steel shell filled with water. The paper introduces the challenges of developing a water-filled façade structure and evaluates the possibility to utilise it as a viable construction system on a building scale. Water-filled glass (WFG) has been researched in the past and it was presented as an independent window element of a conventional building, where energy savings are achieved by using the absorption of the water layer for energy management of the building envelope. The results suggest that WFG’s efficiency could be improved further if the system is assembled as a united building envelope in which the fluid can flow between panels and building parts. The paper presents two experimental ‘water house’ buildings with these design parameters, designed and constructed by the author. The importance of these buildings is that a connected water-filled envelope is built for the first time. The discussion presents two construction methods for water-filled façades, evaluates their viability for different climates, introduces the design-construction aspects of the technology, and offers a comparison with existing construction methods. A fluid-solid building envelope provides significant savings for both operational and embodied energy, by lowering cooling load, reusing absorbed heat, balancing thermal differences between parts of the envelope and the rest of the building, while making additional construction elements (e.g. external shadings) obsolete.

description: Using synchrotron radiation we simultaneously ionize and excite one helium atom of a helium dimer (He_2) in a shakeup process. The populated states of the dimer ion (i.e. He^[*+](n = 2; 3)-He) are found to deexcite via interatomic coulombic decay. This leads to the emission of a second electron from the neutral site and a subsequent coulomb explosion. In this letter we present a measurement of the momenta of fragments that are created during this reaction. The electron energy distribution and the kinetic energy release of the two He^+ ions show pronounced oscillations which we attribute to the structure of the vibrational wave function of the dimer ion.

description: We study the far-from-equilibrium dynamics of isolated two-dimensional Heisenberg antiferromagnets. We consider spin spiral initial conditions which imprint a position-dependent staggered-magnetization (or Neel order) in the two-dimensional lattice. Remarkably, we find a long-lived prethermal regime characterized by self-similar behavior of staggered magnetization fluctuations, although the system has no long-range order at finite energy and the staggered magnetization does not couple with conserved charges. Exploiting the separation of length scales introduced by the initial condition, we derive a simplified analytical model that allow us to compute the spatial-temporal scaling exponents and power-law distribution of the staggered magnetization fluctuations analytically, and find excellent agreement with numerical simulations using phase space methods. The scaling exponents are insensitive to details of the initial condition, in particular, no fine-tuning of energy is required to trigger the self-similar scaling regime. Compared with recent results on far-from-equilibrium universality on the Heisenberg ferromagnet, we find quantitatively distinct spatial-temporal scaling exponents, therefore suggesting that the same model with ferromagnetic and antiferromagnetic initial conditions can host different universal regimes. Our predictions are relevant to ultra-cold atoms simulators of Heisenberg magnets and driven antiferromagnetic insulators.

description: We present results from a comprehensive numerical study of {\it morphological phase separation} (MPS) in unstable thin liquid films on a 2-dimensional substrate. We study the quantitative properties of the evolution morphology via several experimentally relevant markers, e.g., correlation function, structure factor, domain-size and defect-size probability distributions, and growth laws. Our results suggest that the late-stage morphologies exhibit dynamical scaling, and their evolution is self-similar in time. We emphasize the analogies and differences between MPS in films and segregation kinetics in unstable binary mixtures.

description: As the European building stock is in evident need of deep energy retrofitting to meet current European decarbonisation targets, the construction market calls for industrialised systems to boost massive renovations and activate economies of scale. The article outlines the development of an offsite fabricated system for building energy refurbishment through rainscreen façade elements. A focus is placed on such elements as they offer excellent system integration possibilities and the opportunity to boost the level of offsite fabrication, compared to other already industrialised façade systems, such as unitised façades. This research was carried out within the framework of BuildHEAT research project, funded by the European Union Horizon 2020 framework programme. The system concept is based on a systemic approach that combines energy efficiency, multifunctionality, integration of renewable energies, and ease of installation as design drivers. System development has rolled out through different phases, with an increased level of detail. During the schematic design phase, a set of different prefabricated façade panel dimensions were analysed. Afterwards, the component and system integration were assessed according to their impacts in terms of energy performance and fulfilment of mandatory technical requirements. As a last step, the most promising technical combinations underwent detailed design to verify construction feasibility and eliminate any bottlenecks during the fabrication phase. Results show that the proposed prefabricated solutions allowed: (i) simplified active system integration (photovoltaics, solar thermal, and building services), (ii) ease of installation on site, minimising the impact of renovation actions on occupants without compromising on final quality and reducing installation costs. Current limitations to extensive market diffusion of the system are related to two main aspects: (i) the need for on-site adjustments; and (ii) increased manufacturing costs compared to traditional external insulation interventions (e.g. ETICS). The current cost of the system (2020) is in the range of 3 - 1.5x the cost of, respectively, an ETICS or a vented rainscreen façade. However, as a next step, including the life-cycle perspective in the calculation, as well as accounting for economies of scale, the system will be evaluated, expecting a cost figure comparable to the rainscreen façade.

description: The tradition of ceramic façades in Bogotá dates back to more than a century ago. However, this tradition has been characterised by keeping a conventional construction approach, without any considerable evolution. This paper focuses on significant turning points in Bogotá’s tradition that have led to improvements in the construction environment, leading to possible paths for innovation with new proposals for ceramic façades. The central turning-point cases discussed are: Torres del Parque, the North Tower-Hilton International Hotel, brick façades for buildings that emerged after the Colombian Earthquake-resistant Building Standard (NSR-98), and the extension of the Santa Fe Foundation building. Through a detailed focus on these four cases in terms of their technological and morphological solutions, this paper aims to yield innovation opportunities for developing ceramic façade systems within an earthquake prone region.

description: Green screen façades (GSF) remain an unexplored field of study in warm-summer climates with Mediterranean conditions. This research aims to establish whether or not these thermal comfort façade systems are worth developing in cities with dry summers and a high range of thermal oscillation. A comparative study of four buildings´ green screen façades in Santiago de Chile was carried out, with different orientations and plant species, both in type and state of maturity. Temperature and relative humidity outside and inside the cavity were measured during summer days. It was observed that, during the day, interior relative humidity was higher while the temperature was lower, reverting this behaviour during the afternoon and night. This result accounts for the existence of two different daily periods: passive cooling through evapotranspiration in the presence of solar radiation - reaching up to an 8°C temperature reduction and a 30% increase of the relative humidity - and passive heating in its absence. The results show that the determining parameters in the behaviour of a green screen façade in a temperate-warm climate are, first, the orientation of the façade, and second, the density of foliage. Regarding orientation, it was also found that the sun exposure was directly proportional to the performance of a green screen façade.

description: An oxygen hyperstoichiometric ferrite CaBaFe4O7+δ(δ\approx 0.14) has been synthesized using "soft" reduction of CaBaFe4O8. Like the oxygen stoichiometric ferrimagnet CaBaFe4O7, this oxide also keeps the hexagonal symmetry (space group: P63mc), and exhibits the same high Curie temperature of 270 K. However, the introduction of extra oxygen into the system weakens the ferrimagnetic interaction significantly at the cost of increased magnetic frustration at low temperature. Moreover, this canonical spin glass (Tg ~ 166 K) exhibits an intriguing cross-over from de Almeida-Thouless type to Gabay-Toulouse type critical line in the field temperature plane above a certain field strength, which can be identified as the anisotropy field. Domain wall pinning is also observed below 110 K. These results are interpreted on the basis of cationic disordering on the iron sites.

description: The construction sector, identified as one of the largest producers of construction and demolition waste (CDW) and one of the largest energy consumers, demands effective measures and applicable solutions to address sustainability challenges. The closed-loop recycling of CDW, integrated with the large-scale deployment of high energy performing buildings, represents a challenge for the whole construction sector, where the lack of waste efficient and energy efficient envelope systems is identified as one of the main barriers. The aim of this paper is to provide one possible solution to tackle the aforementioned issues – a highly insulated prefabricated ventilated façade panel with concrete layers produced using recycled CDW. The results of extensive research confirm that it is possible to replace a high percentage (50%) of natural coarse aggregate with recycled CDW and produce concrete with good mechanical, durability, and hygrothermal properties. Upscaling from initial research and optimisation at material level to an element level, i.e. development and testing of a ventilated façade panel, demonstrated that it is possible to produce a modular envelope system from recycled CDW that meets all performance requirements for certain construction product type (Declaration of performance and CE-marking). Moreover, the results of hygrothermal and energy consumption field monitoring at the whole building level suggest that the developed panel is suitable for use as a high-performing building envelope in real environmental conditions.

description: Computation-based approaches are increasingly important in architecture, namely Algorithmic Design (AD), which is based on the use of algorithms to generate designs. Besides enhancing design exploration, AD helps architects deal with recurrent design changes and with the pressure to quickly obtain results. Moreover, AD supports the search for better-performing solutions that satisfy environmental demands. Unfortunately, the complexity and specialized knowledge required by AD are still restraining architects due to the amount of effort and time needed to implement the necessary algorithms. To make AD and design optimization techniques more accessible, we propose a theoretical framework to help architects with the algorithmic generation, evaluation, and manufacturing of a large variety of designs, by following a continuous design workflow that merges the typically detached design stages. In order to be useful, the framework needs to focus on a domain of application, and, in this paper, we target the development of buildings’ façades due to their aesthetical and environmental relevance. We evaluate the framework in the context of a real case study resulting from a collaboration between a team of architects specialized in AD and a traditional design studio

description: The design of building envelopes requires a negotiation between qualitative and quantitative aspects belonging to different disciplines, such as architecture, structural design, and building physics. In contrast to hierarchical linear approaches in which various design aspects are considered and conceived sequentially, holistic frameworks allow such aspects to be taken into consideration simultaneously. However, these multi-disciplinary approaches often lead to the formulation of complex high-dimensional design spaces of solutions that are generally not easy to handle manually. Computational optimisation techniques may offer a solution to this problem; however, they mainly focus on quantitative aspects, not always guaranteeing the flexibility and interactive responsiveness designers need in the early design stage. The use of intuitive geometry-based generative tools, in combination with machine learning algorithms, is a way to overcome the issues that arise when dealing with multi-dimensional design spaces without necessarily replacing the designer with the machine. The presented research follows a human-centred design framework in which the machine assists the human designer in generating, evaluating, and clustering large sets of design options. Through a case study, this paper suggests ways of making use of interactive tools that do not overlook the performance criteria or personal preferences.

description: This paper describes the development of an innovative, material- and energy-efficient façade concept: a pneumatically actuated Origami sun shading system - abbreviated “PAOSS” - which combines the aesthetic and material-immanent qualities of textile materials with the functional aspects of a controlled and targeted light transmission regulation by means of integrated active pneumatic components (Fig. 1). Due to the possibility of reducing a given surface to a minimal form, textile-based folding structures are highly suitable for selective sun and glare protection systems, in order to optimise energy consumption and increase user comfort. For astrophysical purposes, the American space agency (NASA) developed an Origami folding geometry called “Starshade,” which is characterised by a particularly high difference between its closed and open state. Inspired by NASA’s “Starshade,” an adaptive, pneumatically actuated sun and glare protection system was designed and developed to be embedded in the cavity of pneumatically supported multi-layer ETFE cushion façades. By implementing active components, one can obtain a targeted, partial, or full-surface regulation of light and radiation transmission as well as the back-reflection properties of the façade. Within the scope of the research project “Adaptive Membrane Façades” funded by the research initiative Zukunft Bau, the PAOSS will be prototypically built at a scale of 1:1 and implemented on one storey of the demonstration high-rise building of the Collaborative Research Centre 1244 entitled “Adaptive Skins and Structures for the Built Environment of Tomorrow.” The goal is the system validation and the monitoring of its reliability and efficiency, especially in terms of building physics and daylight performance under real weather conditions.

description: According to the UNHCR, in 2019 there were 70.8 million refugees worldwide. Due to war, catastrophes, and emergency situations a great demand for temporary accommodation has arisen within the last couple of years. The main requirements for these shelters are protection for the inhabitants, easy transportability, and quick construction. In addition, in terms of resource efficiency, the recyclability of the construction materials is of great importance. Paper materials have a high potential for this, due to their strong structure, cost-effective production, and optimised recycling processes. The following paper presents a case study of a prototype for a temporary paper house that meets the static and technical requirements for a comfortable and hygienic living space by combining different paper materials. The overall objective of this research was the constructive development of building elements made of paper materials, which meet the requirements for temporary residential use over a period of at least 3 years. The main advantages of using paper materials for this purpose are easy processing, cost-effective production, and a high probability for its sustainable disposal after usage. The main challenges of the material are fire protection and moisture protection, which affect the recyclability, as well as the gluing and joining techniques. An overview of possible solutions for these disadvantages and their applicability will be demonstrated and discussed. The paper aims to emphasise that simplicity and performance do not need to be diametrically opposed. The envelope, which provides all the functions required of a modern building through its multi-layered structure, represents the performance of this project. Transportation, construction, and joining, on the other hand, were kept as simple as possible in order to make assembly possible even by unskilled workers and under very basic conditions. The paper is divided into four sections. First, the technical and regulatory requirements for temporary emergency shelters, as well as the decisive characteristics of paper materials are described and analysed. In the second part, the architectural design and the construction typology are defined. The third part focusses on the elaboration and evaluation of building elements with regard to joining technologies, statics, building physics, and production technologies. Finally, the results of the prototype and their transferability are presented and discussed.

description: We derive the first explicit bounds for the spectral gap of a random walk Metropolis algorithm on $R^d$ for any value of the proposal variance, which when scaled appropriately recovers the correct $d^{-1}$ dependence on dimension for suitably regular invariant distributions. We also obtain explicit bounds on the ${\rm L}^2$-mixing time for a broad class of models. In obtaining these results, we refine the use of isoperimetric profile inequalities to obtain conductance profile bounds, which also enable the derivation of explicit bounds in a much broader class of models. We also obtain similar results for the preconditioned Crank--Nicolson Markov chain, obtaining dimension-independent bounds under suitable assumptions.

description: One of the primary challenges prohibiting demonstrations of practical quantum advantages for near-term devices amounts to excessive measurement overheads for estimating relevant physical quantities such as ground state energies. However, with major differences between the electronic and vibrational structure of molecules, the question of how the resource requirements of computing anharmonic, vibrational states can be reduced remains relatively unexplored compared to its electronic counterpart. Importantly, bosonic commutation relations, distinguishable Hilbert spaces and vibrational coordinates allow manipulations of the vibrational system that can be exploited to minimize resource requirements. In this work, we investigate the impact of different coordinate systems and measurement schemes on the number of measurements needed to estimate anharmonic, vibrational states for a variety of three-mode (six-mode) molecules. We demonstrate an average of 3-fold (1.5-fold), with up to 7-fold (2.5-fold), reduction in the number of measurements required by employing appropriate coordinate transformations, based on an automized construction of qubit Hamiltonians from a conventional vibrational structure program.
Photovoltaic Warm Façades with Phase Change Materials in European Climates

Publisher: name: Journal of Facade Design and Engineering
Year: 2021

description: Since façade-integrated photovoltaic (PV) modules heat up greatly, which reduces the efficiency of the PV, façade panels with PV and phase change materials (PCM) were developed. PCMs absorb a significant amount of thermal energy during the phase transition from solid to liquid, while maintaining a specific melting temperature. This cools down the PV and increases the electrical yield. Numerical studies on PV-PCM warm façades without rear-ventilation have so far been missing. Therefore, a thermal and an electrical simulation model for PV-PCM warm façades were developed and validated. They were then used to analyse the yield increase of two PCM-types and -quantities in PV warm façades facing east, south, and west in Athens, Potsdam, and Helsinki. An annual yield increase of 1.2% to 8.5% for monocrystalline PV modules was determined. The maximum monthly yield increase is 8.0% in Helsinki, 11.4% in Potsdam, and 11.3% in Athens. The study shows that a case-specific selection of the appropriate type and quantity of PCM is necessary. Using the models, a design tool for PV-PCM warm façades will be developed. It will be validated with real monitoring data from PV-PCM façade test rigs at the Technische Universität Dresden and the National Technical University of Athens

description: We study the thermodynamic properties of the 3D Hubbard model for temperatures down to the Neel temperature using cluster dynamical mean-field theory. In particular we calculate the energy, entropy, density, double occupancy and nearest-neighbor spin correlations as a function of chemical potential, temperature and repulsion strength. To make contact with cold-gas experiments, we also compute properties of the system subject to an external trap in the local density approximation. We find that an entropy per particle $S/N \approx 0.65(6)$ at $U/t=8$ is sufficient to achieve a Neel state in the center of the trap, substantially higher than the entropy required in a homogeneous system. Precursors to antiferromagnetism can clearly be observed in nearest-neighbor spin correlators.

description: The research project ADAPTEX pursues the goal of developing adaptive, energy-efficient textile sun shading systems using the smart material Shape Memory Alloy (SMA). Within this approach lies a high potential for novel sun protection systems demanding little energy or even self-sufficiently adapting to external stimuli while reducing operation and maintenance costs and at the same time offering solutions to tackle growing demand for sun and glare protection. A Design Categories Matrix is presented that brings together various involved fields from textile design and façade construction to smart material development. Based on this, two concepts have been further elaborated: ADAPTEX Wave and Mesh. Both incorporate SMA into textile structures but express different design and performance potential by changing the geometry and openness factor of the surface area. For further evaluation, various functional prototypes that scale up from 0.2 x 0.2 m to 1.35 x 2.80 m are developed and reviewed. The buildability and functionality of SMA-driven textile sun shading systems that incorporate requirements from the various involved fields are verified. The feasibility of parallel ADAPTEX Wave and Mesh were assessed in comparison to the performance of state-of-the-art sun shading systems. The technological ideas are subsequently optimised and scaled up in various cycles for follow-up testing in both indoor and outdoor environments.

The Coulomb explosion imaging of He_2 provides a direct view of the nuclear wave function of this by far most extended and most diffuse of all naturally existing molecules.

description: The project seeks to create a building envelope that functions as structure, enclosure, and insulation, which is assembled from one solid timber construction element type. Wood has clear environmental benefits when compared to other standard construction materials such as steel and concrete, a good strength-to-weight ratio, relatively high thermal insulation, and low production costs. This research seeks to leverage these characteristics to simultaneously reduce the number of material layers in timber building envelopes while improving the building physics performance. Thus, the environmental impact of buildings can be reduced during planning, construction, operation, and disposal. The project proposes a system that reduces material layers and improves envelope performance by combining contemporary fabrication technologies with traditional woodworking techniques. Design tools should allow for compelling formal opportunities and facilitate fabrication and construction. The system manifests as a free-form, curvilinear log-cabin. Solid timber beams are used to minimise binders and fillers found in composite wood products, and the entire primary construction is achieved with pure wood joinery. CNC machining allows for the precise joining of members to achieve robust, easy-toassemble, structural and airtight façades. By sawing deep slits into solid timber beams, the resulting air chambers improve thermal insulation values up to 30% compared to comparable solid wood assemblies while also relieving naturally occurring internal stresses. Computational design algorithms generate toolpaths and construction data directly from simple input curves, enabling direct coordination of architects, engineers, and contractors. To evaluate the system, multiple prototypes are fabricated to test constructability, thermal conductance, and airtightness, including a demonstrator building to test full-scale implementation. Laboratory tests and the successful completion of the IBA: Timber Prototype House demonstrate the potential for this renewable material to fulfil the requirements of contemporary building envelopes and open the door for the development of all-wood multi-storey façades.

description: In this paper, we discuss the large--time behavior of solution of a simple kinetic model of Boltzmann--Maxwell type, such that the temperature is time decreasing and/or time increasing. We show that, under the combined effects of the nonlinearity and of the time--monotonicity of the temperature, the kinetic model has non trivial quasi-stationary states with power law tails. In order to do this we consider a suitable asymptotic limit of the model yielding a Fokker-Planck equation for the distribution. The same idea is applied to investigate the large-time behavior of an elementary kinetic model of economy involving both exchanges between agents and increasing and/or decreasing of the mean wealth. In this last case, the large-time behavior of the solution shows a Pareto power law tail. Numerical results confirm the previous analysis.

description: We consider two-component one-dimensional quantum gases at special imbalanced commensurabilities which lead to the formation of multimer (multi-particle bound-states) as the dominant order parameter. Luttinger liquid theory supports a mode-locking mechanism in which mass (or velocity) asymmetry is identified as the key ingredient to stabilize such states. While the scenario is valid both in the continuum and on a lattice, the effects of umklapp terms relevant for densities commensurate with the lattice spacing are also mentioned. These ideas are illustrated and confronted with the physics of the asymmetric (mass-imbalanced) fermionic Hubbard model with attractive interactions and densities such that a trimer phase can be stabilized. Phase diagrams are computed using density-matrix renormalization group techniques, showing the important role of the total density in achieving the novel phase. The effective physics of the trimer gas is as well studied. Lastly, the effect of a parabolic confinement and the emergence of a crystal phase of trimers are briefly addressed. This model has connections with the physics of imbalanced two-component fermionic gases and Bose-Fermi mixtures as the latter gives a good phenomenological description of the numerics in the strong-coupling regime.

description: We investigate the sensitivity of three-photon EIT in Rydberg atoms to radio frequency detection and compare it against conventional two-photon systems. Specifically, we model the 4-level and 5-level atomic system and compare how the transmission of the probe changes with different powers of the lasers used and strengths of the RF field. In this model, we also define a sensitivity metric to best relate to the operation of the current best experimental implementation based on shot noise limited detection. We find that the three-photon system boasts much narrower line widths compared to the conventional two-photon EIT. However, these narrow line features do not align with the regions of the best sensitivity. In addition to this, we calculate the expected sensitivity for the two-photon Rydberg sensor and find that the best achievable sensitivity is over an order of magnitude better than the current measured values of 5 uV/m/Hz. However, by accounting for the additional noise sources in the experiment and the quantum efficiency of the photo-detectors, the values are in good agreement.

description: The prospects for detecting a candidate supersymmetric dark matter particle at the LHC are reviewed, and compared with the prospects for direct and indirect searches for astrophysical dark matter. The discussion is based on a frequentist analysis of the preferred regions of the Minimal supersymmetric extension of the Standard Model with universal soft supersymmetry breaking (the CMSSM). LHC searches may have good chances to observe supersymmetry in the near future - and so may direct searches for astrophysical dark matter particles, whereas indirect searches may require greater sensitivity, at least within the CMSSM.

description: In this paper, we simulate the linear absorption spectra of the MePTCDI and PTCDA crystals. The basic Hamiltonian describes the Frenkel excitons and charge-transfer excitons mixing in the molecular stack (point group C_i) and their linear coupling with one vibrational mode of an intramolecular vibration. Using the vibronic approach, we calculate the linear optical susceptibility in the excitonic and one-phonon vibronic regions of the molecular stack and of a crystal with two types of nonequivalent stacks. We put the excitonic and vibrational parameters for the two crystals fitted in the previous studies and analyze some important features of of the linear absorption lineshape in the spectral region of 15 000--23 000 cm^-1 and the virtual positions of many-particle bands. Our study exhibits the necessity of introducing the FE--CTEs mixing in the interpretation of the linear absorption spectra, especially in the MePTCDI crystal.

What makes a façade beautiful?

description: The aesthetic of our built environment is perceived as an important aspect to consider for the design of human-centred cities, but a problem quickly arises in the presence of clashing conceptions of what we understand to be aesthetically pleasing. This paper adds to this discussion, by exploring architects’ aesthetic preferences in façade design, aiming to include design practitioners in a debate that so far has remained largely academic. Thus, the goal of the study was to identify relevant aspects, based on a series of semi-structured interviews with practitioners representing 34 architectural firms from The Netherlands, carried out from January to April 2020. It was possible to identify two major types of aspects, and subsequent sub-groups. Intrinsic aspects (compositional, plastic, detail design, and character) comprise aspects that are characteristic of a façade as an object, while extrinsic aspects (human, intellectual, and contextual connection) consist of relational features, determining the perceived beauty of a façade in terms of its connections with an outside agent. The main identified aspects in each one of the groups, the potential relations among them, and their relative relevance within the surveyed sample were part of the assessment, comparing the outcomes against previous results from the literature.
