Optimal Material

Purpose The purpose of this paper is to implement the generative design as an optimization technique to achieve a reasonable trade-off between weight and reliability for the control arm plate of a double-wishbone suspension assembly of a Formula Student race car. Design/methodology/approach The generative design methodology is applied to develop a low-weight design alternative to a standard control arm plate design. A static stress simulation and a fatigue life study are developed to assess the response of the plate against the loading criteria and to ensure that the plate sustains the theoretically determined number of loading cycles. Findings The approach implemented provides a justifiable outcome for a weight-factor of safety trade-off. In addition to optimal material distribution, the generative design methodology provides several design outcomes, for different materials and fabrication techniques. This enables the selection of the best possible outcome for several structural requirements. Research limitations/implications This technique can be used for applications with pre-defined constraints, such as packaging and loading, usually observed in load-bearing components developed in the automotive and aerospace sectors of the manufacturing industry. Practical implications Using this technique can provide an alternative design solution to long periods spent in the design phase, because of its ability to generate several possible outcomes in just a fraction of time. Originality/value The proposed research provides a means of developing optimized designs and provides techniques in which the design developed and chosen can be structurally analyzed.

The use of generative design has been suggested to be a novel approach that allows designers to take advantage of computers’ computational capabilities in the exploration of design alternatives. However, the field is still sparsely explored. Therefore, this study aimed to investigate the potential use of generative design in an architectural design context. A framework was iteratively developed alongside a prototype, which was eventually demonstrated in a case study to evaluate its applicability. The development of a residential block in the northern parts of Sweden served as the case. The findings of this study further highlight the potential of generative design and its promise in an architectural context. Compared to previous studies, the presented framework is open to other generative algorithms than mainly genetic algorithms and other evaluation models than, for instance, energy performance models. The paper also presents a general technical view on the functionality of the generative design system, as well as elaborating on how to explore the solution space in a top-down fashion. This paper moves the field of generative design further by presenting a generic framework for architectural design exploration. Future research needs to focus on detailing how generative design should be applied and when in the design process.

Practical Implications

Purpose – The Government of UK is committed to reducing Green House Gas emissions by 80 per cent based on the 1990 levels, by 2050. In order to achieve this reduction, the UK Government, along with their European counterparts, have implemented various directives and incentives, which progressively and incrementally are intended to move them towards this target. One such directive is the European Energy Performance of Buildings Directive, which sets the policy for achievement. The paper aims to discuss these issues. Design/methodology/approach – This paper seeks to examine the complexities of these changes when considered against the real world use and operation of buildings, most particularly at lease end. It explores the inter-relationship of landlord and tenant at lease expiry and renewal. Findings – It argues that the Energy Act regulations might have significant impact on the actions of landlords and tenants; both in advance of and shortly after the lease is determined. Practical implications – One of the key mechanisms contained within this directive for the reduction in emissions is the Energy Performance Certificate (EPC). An EPC must be produced where a building is being constructed, rented or sold. EPCs rate buildings on their asset energy performance and in conjunction with building regulations are becoming increasingly more stringent to achieve targets. Regulations under the Energy Act 2011, due to take effect from April 2018, will mean that it will be unlawful to let or re-let a building which fails to reach minimum energy performances standards, currently defined as an E rating; further it is intended that the regulations will extend to all lettings from 2023. Originality/value – This paper looks at the inter-relationship of landlord and tenant at lease expiry and renewal with the proposed directives on EPCs.

Transaction Database

Purpose This paper aims to estimate the green premium effect of retrofitted apartments in Bucharest and draw comparisons with international examples. Design/methodology/approach A geo-referenced transaction database including information on whether the property had been retrofitted is utilised. The paper uses two approaches to test the green premium. One is a hedonic model controlled by areas to estimate the price incentive of a green building. The second is a STAR GLS model evaluating the diffusion effect of house prices spatially by sub-market and assessment upon the pricing effect of green characteristics. Findings The authors’ findings suggest a green premium in two Bucharest areas of between 2.2 per cent and 6.5 per cent. Spatial diffusion effects are shown to contribute positively to house prices, but the unobserved spatial component reduces this effect. Originality/value This paper is the first to assess price impacts of green characteristics in Bucharest and one of the first analysing green premium using spatial techniques. The analysis is of significance to policymakers and real estate developers.
