title	DAttE - Detection of Attic Extensions - Workflow to analyze the potentials of roofs in an urban environment
source	Stojakovic, V and Tepavcevic, B (eds.), Towards a new, configurable architecture - Proceedings of the 39th eCAADe Conference - Volume 1, University of Novi Sad, Novi Sad, Serbia, 8-10 September 2021, pp. 375-384

summary	European cities like Vienna are characterized by strong growth and, as a result, by high demand for living space. Extending the attic is one way of meeting this demand. However, there is a lack of data to know which roofs are already expanded and to what extent. The city is interested in the data in two ways: firstly, in relation to the distribution of potentials (a possible change in population density, for example, has an impact on infrastructure and parking space) and, secondly, in relation to the material composition (city as a material resource). This paper provides a workflow to fill this gap of knowledge. The new methods of detecting attic extensions are described and a case study is given at the end to show workability.

summary	The concept of describing and analyzing architecture from a fractal point of view, on which this paper is based, can be traced back to Benoît Mandelbrot (1981) and Carl Bovill (1996) to a considerable extent. In particular, this includes the distinction between scalebound (offering a limited number of characteristic elements) and scaling objects (offering many characteristic elements of scale) made by B. Mandelbrot (1981). In the fi rst place such a differentiation is based upon a visual description. This paper explores the possibility of assistance by two measurement methods, fi rst time introduced to architecture by C. Bovill (1996). While the box-counting method measures or more precisely estimates the box-counting dimension D b of objects (e.g. facades), range analysis examines the rhythm of a design. As CAD programs are familiar to architects during design processes, the author implemented both methods in AutoCAD using the scripting language VBA. First measurements indicate promising results for indicating the distinction between what B. Mandelbrot called scalebound and scaling buildings.

summary	Referential structures in digital representation and those structures that have established contemporary canons have been progressively negated. As a result of this tendency, post-structuralism, as a pendulous reactionary force against structuralism, broke away from deconstruction’s conceptual premise: to produce a full decomposition of any assumed disciplinary fundamentals. Therefore, rather than focusing on a syntax based on structural logics, current digital architecture tendencies hide deep conceptual structures in favor of superficial perceptual structures, relying on the media-based spectacular semiotic effect of the visual that has exhausted its capacity to be critical.

title	Constraint-based support for negotiation in collaborative design
source	Artificial Intelligence in Engineering, Vol: 14, Issue: 3, pp. 261-280.
summary	Solution spaces are proposed, instead of single solutions only, to support collaborative tasks during design and construction. Currently, partners involved in construction projects typically assign single values for sub-sets of variables and then proceed, often after tedious negotiations with other partners, to integrate these partial solutions into more complete project descriptions. We suggest the use of constraint solving to express possibly large families of acceptable solutions in order to improve the negotiation process in two ways. On one hand, con ict detection can be performed in an automated manner. Through the constraints collaborators impose, they de ne large unfeasible areas where no solution to the problem at hand can be expected. An emty intersectidon of the solution spaces can thus point at a con ict of design goals of the di erent collaborators at an early stage of the design process. On the other hand, important decision support during negotiation is provided. When a solution space is found, collaborators know during negotiation that they are negotiating about feasible solutions. Negotiation is no longer a means to nd a solution to the problem but it takes place in order to nd a good or the best solution. Since the consistency of the design remains ensured, collaborators are expected to be less restrictive towards innovative ideas during negotiation. Moreover, constraint techniques using explicit representations of solution spaces can provide tools to visualize trade-o s and illustrate the impact of certain decisions on other parameters. Thus decision-making is improved during the negotiation. New algorithms have been developed at EPFL for solving multi-dimensional nonlinear inequality constraints on continuous variables. Together with intuitive user interfaces such constraint-based support leads to better change management and easier implementation of least commitment decision strategies. It is expected that the results of this research can improve both the e ciency of negotiation processes and the quality of the achieved results.

title	Methods to assist the design of road surfaces with a reservoir structure: To improve flood risk management
source	Timmermans, Harry (Ed.), Third Design and Decision Support Systems in Architecture and Urban Planning - Part two: Urban Planning Proceedings (Spa, Belgium), August 18-21, 1996
summary	Reservoir road surfaces can be seen as equipment of the future, in that they have two functions in the same structure (circulation and hydraulic functions). They can thus be laid without immobilising land, which is very expensive and prized in urban areas. Furthermore, they enable the limitation of the flow or volumes of running water, and thus help control rainwater, resulting in better flood risk management. The questions asked by drainage designers are how can we design these structures in the best way? How are they going to work for different types of rain (rain from storms, prolonged winter rain ....)? As for the public administrators, they wonder how a series of areas equipped with this type of technique (total flow management) would work. By solving this latter problem, we could really arouse interest in flood risk management. Given the diversity of structures possible for reservoir road surfaces (regulated, non-regulated, draining surface, dispersion surface...), we suggest comparing design and simulation methods, taking into account the measurement and total flow management problems mentioned above. So as to validate these comparisons and to give some directions concerning the use of one or the other methods, we use flow-metre measures on two different sites in Lyons. One of these sites is a car- park on a tertiary activity zone on the La Doua campus in Villeurbanne, the other a refuse dump in the Greater Lyons area in the town of Craponne. They are both interesting as they have different features. The first is non-regulated downstream and is used on a car-park for light motor-vehicles. The other is regulated and the traffic on it is made up of lorries. These sites will be described in this article.

title	Connect, Motivate, Communicate: A Foundation for Gamification in Planning Communication
source	SIGraDi 2018 [Proceedings of the 22nd Conference of the Iberoamerican Society of Digital Graphics - ISSN: 2318-6968] Brazil, São Carlos 7 - 9 November 2018, pp. 1105-1111
summary	Planning in the urban context is always a complex task in which the diverse interests of different stakeholders have to be weighed up against each other. For this to happen, communication is the key leading to successful and sustainable solutions. Often objective factors like the number and diversity of participating stakeholders is the benchmark for successful planning processes. We examine the motivational factors of the different main stakeholder groups and give an insight in the complex system of motivational and hindering factors that need to be considered when designing engaging sensible and sustainable exchange of knowledge and interests.

title	Evaluation of IT costs in construction
source	Automation in Construction 10 (6) (2001) pp. 649-658
summary	Information Technology (IT) evaluation is a research area that has received limited attention in the construction and engineering literature. Yet, the justification of investments in IT is one of the many challenges facing managers in the construction industry today, as there is an ever-increasing demand for organisations to improve the efficiency and effectiveness of their IT deployments. In developing a deeper understanding of the evaluation process, the authors of this paper present a review of IT evaluation in construction from a benefit and cost perspective. In doing so, identifying future challenges for IT cost evaluation research in construction.

title	Intelligence in buildings: the potential of advanced modelling
source	Automation in Construction 6 (5-6) (1997) pp. 447-461
summary	Intelligence in buildings usually implies facilities management via building automation systems (BAS). However, present-day commercial BAS adopt a rudimentary approach to data handling, control and fault detection, and there is much scope for improvement. This paper describes a model-based technique for raising the level of sophistication at which BAS currently operate. Using stochastic multivariable identification, models are derived which describe the behaviour of air temperature and relative humidity in a full-scale office zone equipped with a dedicated heating, ventilating and air-conditioning (HVAC) plant. The models are of good quality, giving prediction accuracies of ± 0.25°C in 19.2°C and of ± 0.6% rh in 53% rh when forecasting up to 15 minutes ahead. For forecasts up to 3 days ahead, accuracies are ± 0.65°C and ± 1.25% rh, respectively.The utility of the models for facilities management is investigated. The "temperature model" was employed within a predictive on/off control strategy for the office zone, and was shown to substantially improve temperature regulation and to reduce energy consumption in comparison with conventional on/off control. Comparison of prediction accuracies for two different situations, that is, the office with and without furniture plus carpet, showed that some level of furnishing is essential during the commissioning phase if model-based control of relative humidity is contemplated. The prospects are assessed for wide-scale replication of the model-based technique, and it is shown that deterministic simulation has potential to be used as a means of initialising a model structure and hence of selecting the sensors for a BAS for any building at the design stage. It is concluded that advanced model-based methods offer significant promise for improving BAS performance, and that proving trials in full-scale everyday situations are now needed prior to commercial development and installation.

summary	This paper presents the development and implementation of a novel pilot course for undergraduate design students, with a focus on the integration of electronics and data-driven methodologies within the field of design. The course was structured around a real-world project that addressed the challenges encountered by senior individuals. It incorporated user-centered design principles, sensor-based data collection, real-world deployment, and data-based design assessment. The results demonstrated the successful application of data-driven methods, and an appreciation by students for the empirical foundation in design decisions. The pilot confirms that data-driven approaches can be successfully embedded within an undergraduate design program, offering valuable insights for educators interested in pursuing such integrative pedagogical methods.

summary	Participatory planning aims at engaging multiple stakeholders including citizens in various stages of planning projects. Adopting participatory design approach in the early stage of planning project facilitates the ideation process of citizens. We have implemented a participatory design study during the 2017 Beijing Design Week and have conducted an interactive design project called "Design your perfect Dashilar: You Place it!". Participants including local residents and visitors were asked to redesign the Yangmeizhu street, a historical street located in Dashilar area by rearranging the buildings of residential, commercial, administration, and cultural functionalities. Apart from using digital design tools, questionnaires, interviews, and sensor network were applied to collect personal preferences data. Computational approaches were used to extract features from designs and personal preferences. In this paper, we illustrate the implementation of the participatory design and the possible applications by combining with crowdsourcing. Participatory design data and citizens profiles with personal preferences were analysed and their correlations were computed. By using crowdsourcing and participatory design, this study shows that the digitalization of participatory design with data science perspective can indicate the implicit requirements, needs and design ideas of citizens.

summary	This paper describes the design and fabrication process of an adaptive joint using foldable 3D printed structures encased in heat-sealed synthetic polymer films (e.g. airtight plastic casing). The proposed joint can be pneumatically actuated using the airtight casing, and the shape of the deformation can be controlled using origami-inspired 3D printed structures. A zigzag-gap microstructure is designed for the connection portion of the origami structure inside the joint, in order that the rigid 3D printed material (PLA) acquires properties of mollusk material, such as flexibility and softness. Finally, the paper presents some applications adopting pneumatic origami joints which can interact with people or adapting indoor environment, and compares the advantages of this pneumatic technology with mechanical technology.

summary	On-site construction is one of the main research directions of robot construction. Due to the complex and everchanging construction environment on the site, traditional offline programming and simple conditional programming cannot meet the needs of robot on-site construction at all. Realtime adjustment of the robot's operating program for the real-time situation in the field is the appropriate solution. Therefore, the real-time communication and control of robots has become a key issue for robot on-site construction. This article discusses in turn the way of robot offline program control through EthernetKRL and grasshopper. A remote real-time communication and control method for an on-site construction robot is studied, and the application of the method in the on-site construction process of an actual robot is introduced with the Wuzhen coffee kiosk project as an example. Based on the above methods, remote real-time monitoring of the construction robot on site can be realized, which provides a reference for the actual engineering application of the construction robot on site.

summary	With the increase in labor costs, more and more robot constructions appear in building construction and spatial structure fabrication. There are many robots working on large-scale objects. When the reach range of the robot cannot meet the requirements, so an external axis is needed. The external axis is usually a linear motion device, which can significantly increase the operating range of the robotic arm. In actual construction, it is also widely used. This article introduces a 3d printing coffee bar project. Because this project is of a large scale and needs to be printed at one time, the XYZ external axis was used in this project to complete the task. Inspired by this project, this article study several methods of optimizing the motion of external axes in large-scale construction. Finally, we chose to use the Fourier series as the most suitable method to optimize the printing path and programed this method as a component of FUROBOT for more convenient use. This article explains the principle of this method in detail. Finally, this article uses a 3D printing example to illustrate the precautions in actual use.

summary	With the rapid development of digital design methods, irregular curved shapes have been more and more widely used in buildings, which not only enriches the appearances of buildings, but also provide new possibilities of improving building performance by shape designs. However, existing researches regarding building performance and shapes mostly focus on regular shapes, while curved shapes are rarely explored. This paper aims to employ design optimization method to explore the improvement of building performance that curved shapes could contribute. Specifically, office buildings are chosen as an example and the potential of improving the daylight efficiency of them by optimized curved facades are investigated. Three major cities and two orientations are involved in the investigation. The results prove that curved facades do have significant potential to improve the daylight efficiency of office buildings, and an average improvement of 0.2032 is achieved by the optimized curved facades in the 6 cases conducted in this research in terms of the area-weighted average UDI (useful daylight illuminance) compared with the same building with plane facade.

summary	As one of the most important building systems, HVAC plays a key role in creating a comfortable thermal environment. Predicted Mean Vote (PMV), an index that predicts the mean value of the votes of a large group of persons on the thermal sensation scale, has been adopted to evaluate the built environment. Compared to environmental factors, clothing insulation can be much harder to measure in the field. The existing research on real-time clothing insulation measurement mainly focuses on expensive infrared thermography (IR) cameras. Therefore, to ensure cost-effectiveness, the paper has proposed a solution consisting of a normal camera, IR and air temperature sensors and Arduino Nanos to measure clothing insulation in real-time. Moreover, the algorithm includes the initialization from clothing classification with pre-trained neural network and optimization of the clothing insulation calculation. A total of 8 tests have been conducted with garments for spring/fall, summer and winter. The current results have shown the accuracy of T-shirt classification can reach over 90%. Moreover, compared with the results with IR cameras and reference values, the accuracies of the proposed sensing system vary with different clothing types. Research shall be further conducted and be applied into the dynamic PMV-based HVAC control system.
