The double-skin façade (DSF) is one of the most crucial paradigms of building envelope design in last decades. DSF prospects a unified architectural phenomenon based on comfort rank of building driven by the dogmas of aesthetic-glass façade and practical-natural ventilation aspirations. Therefore, the utilization of DSF has been the most prevalent catalyst for architectural design. The study discusses to structure a valid evaluation method focusing on DSF elements in order to fragment human comfort standards within asserting an accurate system in the preliminary design stage. The study significantly examines the tools/ways of integrating DSFs' human comfort parameters in contemporary architecture though a convincing design system. Apparently, the study aims to provide a proposed guideline within a established analyzing system for architects in order to better formation of DSF elements; which refers and promote the human comfort standards. The results demonstrate a modest insight on understanding the potentials of DSF elements in the early design stage significantly following defined architectural conceptions; cooling, lighting, thermal, acoustic and visual comfort intensity. Based on obtained data; study aims to enclose a diminutive knowledge or demonstration of how the concept might work for future development of contemporary architecture within DSF area.

Huge efforts have been made in recent decades to improve energy saving in the building sector, particularly focused on the role of façades. Among the explored viable solutions, climate-adaptive building shells [CABS] consider promising solutions to control solar radiation, both in terms of illuminance and heating levels, but are still piloting these solutions due to their complex designs and necessary costs. The present study aims to provide a speedy but reliable methodology to evaluate the potential impacts of adopting active/passive CABS systems during the preliminary design stage. The proposed methodology allows the evaluation and comparison, when multiple options are considered, of the effects of each solution in terms of the energy needs, thermal comfort and lighting, while reducing the required effort and time for an extensive analysis of the overall building level. This is based on the use of a “virtual test room” where different conditions and configurations can be explored. A case study in the city of Bologna is included for demonstration purposes. The achieved results support the decisions made regarding energy behavior (over/under heating), indoor comfort, lighting and energy at an early design stage.

In engineering applications, human comfort fulfillment is challenging because it depends on several aspects that can be mathematically controlled and optimized, like in case of structural, energy, or thermal issues, and others. Major troubles can indeed derive from combined human reactions, which are related to a multitude of aspects. The so-called “emotional architecture” and its nervous feelings are part of the issue. The interaction of objective and subjective parameters can thus make the “optimal” building design complex. This paper presents a pilot experimental investigation developed remotely to quantify the reactions and nervous states of 10 volunteers exposed to structural glass environments. As known, intrinsic material features (transparency, brittleness, etc.) require specific engineering knowledge for safe mechanical design but can in any case evoke severe subjective feelings for customers, thus affecting their psychological comfort and hence behaviour and movements. This study takes advantage of static/dynamic Virtual Reality (VR) environments and facial expression analyses, with Artificial Intelligence tools that are used to measure both Action Units (AUs) of facial microexpressions and optical heart rate (HR) acquisitions of volunteers exposed to VR scenarios. As shown, within the limits of collected records, the postprocessing analysis of measured signals proves that a rather good correlation can be found for measured AUs, HR data trends, and emotions under various glazing stimuli. Such a remote experimental approach could be thus exploited to support the early design stage of structural glass members and assemblies in buildings.

Early Stage Design

Artificial Intelligence and especially machine learning have noticed rapid advancement on image processing operations. However, its involvement in the architectural design is still in its initial stages compared to other disciplines. Therefore, this paper addresses the issues of developing an integrated bottom up digital design approach and details a research framework for the incorporation of Deep Convolutional Generative Adversarial Network (GAN) for early stage design exploration and generation of intricate and complex alternative facade designs for urban infill. This paper proposes a novel building facade design by merging two neighboring building’s architecture style, size, scale, openings, as reference to create a new building design in the same neighborhood for urban infill. This newly produced building contains the outline, style and shape of the parent buildings. A 2D urban infill building design is generated as a picture where 1) neighboring buildings are imported as a reference using mobile phone and 2)iFACADE decode their spatial adjacency. It is depicted the iFACADE will be useful for designers in the early design stage to generate new façades depending on existing buildings in a short time that will save time and energy. Besides, building owners can use iFACADE to show their architects their preferred architecture facade by mixing two building styles and generating a new building. Therefore, it is depicted that iFACADE can become a communication platform in the early design stages between architects and owners. Initial results properly define a heuristic function for generating abstract design facade elements and sufficiently illustrate the desired functionality of our developed prototype.

Profile Loss

Reasonably accurate estimation of losses at an early design stage plays an important part in the success of a turbine design. Although various computational methods exist for estimating the profile loss, for secondary losses which are equally important, designers still rely on emprical estimates. A method has been developed for estimating the secondary flow and secondary losses within an axial turbine cascade. It is assumed that the inlet boundary layer is convected into a loss core within the blade passage while extra loss has been generated due to the secondary kinetic energy and a new boundary layer that is developing on the end wall. The method has been applied to various test cases and the results show that the basic approach is reliable.
