In the presented research, in addition to the Employer, technical individuals were involved in the decision-making process. The harmonisation of Employer opinions and those of experts were obtained through NGT technique and Delphi based method, due to the fact that different criteria for a decision could represent a field of interest of an individual participant in the process. The result was determining the criteria, their strictness, and their weighted effect. As multi-criteria decision analysis has evolved into a powerful tool that assists decision-makers in generating “a cut above” choice in resolving specific cases and overcoming certain problems in the architectural and construction industry, the use of the MCDM method EDAS+ in the research ensured an exterior wall system ranking that was not influenced by experience or marketing.</p> <p>Without intending to favour any manufacturer of building materials, the research presents eight exterior wall systems belonging to different categories of core materials, all with individual features, similarities, and differences.</p> <p>When compared to otherwise arbitrary estimates or recommendations based on experience and the most commonly used building materials, the application of multi-criteria decision analysis in the case of exterior wall system selection for a particular 1938 Belgrade building generated more relevant selection results.</p> Anđelka Štilić Igor Štilić Copyright (c) 2022 2022-06-01 2022-06-01 10 1 001 0028 10.47982/jfde.2022.1.01 Exploring the Impact of Geometry and Fibre Arrangements on Daylight Control in Bistable Kinetic Shades <p>Bistable laminates are composite structures that exhibit more than one static configuration, showing a "snap-through" behaviour that results from residual stresses generated during the curing process. 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.</p> Elena Vazquez Jose Duarte Copyright (c) 2022 Elena Vazquez, Jose Duarte 2022-11-04 2022-11-04 10 1 10.47982/jfde.2022.1.03 Towards a Human Centred Approach for Adaptive Façades <p>Adaptive façades are multifunctional systems that are able to change their functions, features, or behaviour over time in response to changing boundary conditions or performance requirements. 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.</p> Mine Koyaz Alejandro Prieto Aslıhan Ünlü Ulrich Knaack Copyright (c) 2022 2022-06-01 2022-06-01 10 1 029 054 10.47982/jfde.2022.1.02
