This paper presents a framework for an analysis method and computational tool, which evaluates the fabrication parameters of complex geometries. The suggested method predicts the feasibility, material use, and machining time required for fabricating the moulds for these geometries. It achieves this by interrogating geometric properties instead of the traditional machining simulations. Using the algorithms developed in this research, the method can provide real time evaluation of computer-controlled mould fabrication techniques such as cutting and assembling sheet materials, multi-axis milling of volumetric material, and robotic hot wire cutting. In the paper, we describe the mathematical basis of the suggested method. We demonstrate how the method provides real-time visual feedback for designers and allows them to adjust their design according to fabrication constraints in the early design stages. Using architectural case studies, we show how the analysis results provide precise cost estimates and help minimize fabrication resources in manual or automatic fabrication optimization processes.

This study investigates the influence of window system configurations on the energy use/cost, access to daylight and view, visual comfort and environmental performance in a one-bed hospital patient room located in a temperate climate. The methodology combines dynamic energy simulations, visual comfort and daylight analysis in a life cycle assessment study of window systems, covering a wide range of environmental indicators. In this study, multi-criteria evaluation approach is used to analyse the different design alternatives. A graphical optimization method was elaborated to filter the solutions and select the most appropriate window design based on project objectives and architectural preferences. The results show that glazing with ‘0.30 < g-values≤0.50’ and ‘0.50 < Tvis < 0.75’ have lower energy use and/or cost, lower environmental impacts while maintaining sufficient daylight levels (sDA > 55%) and showing higher quality for visual comfort. These type of glazing allows for using bigger windows which leads to a higher percentage of the outside view.

The paper discusses the importance of greenery in cities. It considers the presence of green elements inside a typical urban perimeter block and deliberates about their impact on the solar radiation level on the facades and the yard. A series of computer simulations have been done using six combinations of surface reflectance (façade/yard) for six perimeter block configurations. The simulations were performed with DIVA, a plug-in for Rhino for Oslo (59.91273, 10.74609). The results confirm that a modest amount of greenery causes only a small reduction of the radiation, up to 11% in the yard and up to 13% in the lower parts of facades. Surface reflectances are important. The increase of façade reflectance from 22% to 66% is more than enough to compensate for adding green elements, e.g. one large birch and three smaller ever-green conifers.

Emergency evacuation is a significant matter in high-rise buildings, as large numbers of occupants are in limited space. Evacuation standards and codes used by designers are closely related to interior spaces. However, the relationship between the general geometric shape of buildings and the evacuation process are major gaps in the literature. In this paper, we assessed the effect of three geometric parameters related to the general geometric shape of the building, namely the gyration radius, the average length and width of the bounding rectangle, and the ratio of the perimeter to the area of the shape on the travel time by using the agent-based method. The results show that gyration radius has the most direct relationship with the time of total travel and horizontal travel time and can be used as a suitable tool in the initial design stage used by architects and designers of buildings.

Dwellings on hillsides require complex design and construction techniques, resulting in low productivity and high cost. Urban hillsides often feature low-density individual houses with private gardens or high-density informal settlement with lack of green spaces and compromised liveability. By contrast, densely built historic hill-towns are admired in the context of tourism for their setting and spatial coherence. This article proposes a design process, which combines design knowledge and parametric design. The research employs a mixed methodology, combining design research, computer simulation, and case study. Based on dwelling design and aspects of fabrication/installation, a shape grammar of dwelling modules is developed, which are set-out and combined with a rule-based, generative design algorithm. The process allows for the design of high-density settlements, comprising low-rise dwellings, with topography and principles of serial construction as design generators. The resulting two-stage parametric design tool is tested and refined on a case-study site in Wellington (NZ).

Light Transmitting Building Block (LTBB) is a building block with transparent rods embedded in it that allows transmission of light. It was recently granted a patent in 2020 in India and so, there is no further information available on its light-transmitting performance. The paper analyzes the data generated from the experiment performed in Patna, India on its light transmitting capacity for daylighting. Many factors are involved that have an impact on the light transmitting capacity of the LTBB (Model 1). Experiment for light transmittance were also carried out for the block without embedded transparent rods (Model 2) and compared with Model 1. It is found that light transmitting performance of Model 1 was significantly better than Model 2. Further, the requirement of the number of blocks of Model 1 was calculated for generating the recommended level of illumination for specific indoor activities through a software simulation using DIALux.

Urban environments face the serious challenge of complying with relatively tight constraints regarding land and tenant density. In fact, this has become a key constraint in both current and future urban designs. Moreover, wellbeing is strongly influenced by urban planning and design decisions. The objective of this study was to examine the effect of spatial parameters on the wellbeing of potential dwellers through VR experiments. The research incorporated two experiments that were conducted in a VR laboratory, by manipulating virtual twins of an existing urban environment. The first experiment focused on increased density levels combined with commerce and vegetation, while the second one focused on variant morphologies within a fixed density level. The results indicate that morphology, density, vegetation, and commercial activity have a significant impact on people’s wellbeing. The findings of this research emphasize certain design principles that could improve urban designs that are part of densification processes.

Due to the increasing amount of time that people are spending indoors, the need to ensure adequate ventilation has become a priority. The confirmed airborne transmission of COVID-19 highlights the necessity to consider the effect of ventilation on the reduction of the infection risk. In naturally ventilated buildings, the ventilation rate is not easy to determine, and it is difficult to estimate the risk to implement preventive measures. This paper presents a method to estimate the infection probability from CO2 concentration monitoring, which was applied to university classrooms. The effects of people’s activity, classroom characteristics, occupancy and protective masks were also investigated. From the method, it is possible to calculate the infection probability using CO2 dataloggers that can be adopted as ‘alarm’ systems to keep the infection probability below a critical value. The method will enhance healthy conditions indoors and reduce the risk of infectious diseases in the future.

This research investigated how exposure to moisture influences the biodeterioration of facade finishes in the hot-humid tropics of Enugu metropolis, Southeast Nigeria. Physical observations and experimental research strategy were used to collect data from 383 buildings in the study area. The data were analysed using descriptive and logistic regression analyses. The results showed that 53.5% were residential buildings and 88.5% had cementitious façade finishes with 66.8% of them having their façade finishes exposed to moisture. Further, 64% of the facade finishes, mainly of cementitious materials and paints were colonized by microorganisms with the most common microbes being fungi. Façade finishes exposed to moisture we found to be four times more likely to experience biodeterioration. The study concludes that in order to curb microbial colonization of façade finishes and the attendant adverse effects, architects should engage in design strategies that can minimize the level of exposure of façade finishes to moisture.

Achieving indoor thermal comfort is essential for productivity, especially in educational environments, and hence has recently attracted considerable attention. Phase change materials (PCMs) integrated into various building components have been used to improve the indoor temperature. In this study, the effectiveness of integrating macro-encapsulated BioPCMs into the walls and ceilings of lecture halls in an educational building was determined via simulation. The simulations considered a hot climate coupled with controlled night ventilation of 15 air change per hour for enhancing the indoor temperature. Using the EnergyPlus software, simulations were performed for different PCM melting temperatures (25, 27 and 29°C) and thicknesses. The PCM with a melting temperature of 27°C yielded a notable reduction (0.5–3.3°C) in the indoor temperature. Furthermore, increasing the layer thickness to 3.75 cm had little effect on the temperature, as indicated by the incomplete charging process during the night. GRAPHICAL ABSTRACT
