Abstract

Purpose

The central motivation for this study was to examine alternatives against the apartment area reduction as a safe way to reduce construction costs, adopted by many construction companies. From the building economic compactness index concept, it was studied the cost and environmental impacts (material consumption, embodied energy – EE and CO2 emission).

Design/methodology/approach

The research strategy takes advantage of a case study aiming to investigate the relation between design characteristics related to area (m²) and building economic compactness index (%) with cost (Research Stage 1) and with environmental impacts: (Research Stage 2). The study involved real data from social housing projects, chosen in terms in terms of very similar features like size, area and constructive method (constants), however, with dissimilar compactness (variable).

Findings

The lack of direct relation between area and cost signs the importance of including the cost of vertical plans considered in the economic compactness building. The higher the economic compactness index, the lower the cost, the lower the amount of material, EE and CO2 emission parameters. However, due to the wide range of EE and CO2 values available, the reduction in the amount of materials achieved by increasing building economic compactness index may not be reflected in EE and CO2 gains.

Research limitations/implications

As the limitation of this study, it must be taken into account a limited number of case buildings and the fact that the analysis is dependent on the reliability and accuracy of the data provided by constructors and the available information of EE and CO2 emission. As well discussed in the literature, the consistent database is a great challenge for the construction sector.

Originality/value

There might be alternatives to higher areas with relatively low-cost increments since results from buildings with the same area present different cost estimative and suggest a strong relationship with the economic compactness index. The large variation of EE and CO2 emission data indicates that reductions obtained by compactness increase may be impaired if the construction materials are produced with high levels of EE and CO2 emission. Thus, there must be an integrated effort on the part of designers (design and material specification) and manufacturers (material production), since isolated solutions may not be enough.

Abstract

Purpose

This study aims to develop a methodology that extracts an architectural concept from a biological analogy that integrates forms and kinetic behavior to identify whether complex forms work better or simple forms with proper kinetic behavior for improving visual comfort and daylight performance.

Design/methodology/approach

The research employs a transdisciplinary approach using several methods consisting of a biomimetic functional-morphological approach, kinetic design strategy, case study comparison using algorithmic workflow and parametric simulation and inverse design, to develop an interactive kinetic façade with optimized daylight performance.

Findings

A key development is the introduction of a periodic interactive region (PIR), which draws inspiration from the butterfly wings' nanostructure. These findings challenge conventional perspectives on façade complexity, highlighting the efficacy of simpler shapes paired with appropriate kinetic behavior for improving visual comfort. The results show the façade with a simpler “Bookshelf” shape integrated with a tapered shape of the periodic interactive region, outperforms its more complex counterpart (Hyperbolic Paraboloid component) in terms of daylight performance and glare control, especially in southern orientations, ensuring occupant visual comfort by keeping cases in the imperceptible range while also delivering sufficient average spatial Daylight Autonomy of 89.07%, Useful Daylight Illuminance of 94.53% and Exceeded Useful Daylight Illuminance of 5.11%.

Originality/value

The investigation of kinetic façade studies reveals that precedent literature mostly focused on engineering and building physics aspects, leaving the architectural aspect underutilized during the development phase. Recent studies applied a biomimetic approach for involving the architectural elements besides the other aspects. While the biomimetic method has proven effective in meeting occupants' visual comfort needs, its emphasis has been primarily on the complex form which is difficult to apply within the kinetic façade development. This study can address two gaps: (1) the lack of an architectural aspect in the kinetic façade design specifically in the development of conceptual form and kinetic behavior dimensions and (2) exchanging the superficial biomimetic considerations with an in-depth investigation.

Abstract

Purpose

Drawing on the service-dominant logic and the institutional theory, this paper aims to explore the value-creating mechanisms of branding in the destination context and the brand co-creation process at and between different levels of a service ecosystem.

Design/methodology/approach

An exploratory research design was used to generate qualitative data from 18 in-depth interviews with important stakeholders and investigate how and why brand co-creation is fostered in the service ecosystem.

Findings

The study proposes a stepwise process of strategic imperatives for brand co-creation in the destination context. It presents the multi-directional flows of the brand meaning across levels of the tourism ecosystem and thereby interprets stakeholders’ efforts to co-create sustainable brands that gain prominence in the global tourism arena.

Research limitations/implications

Future research might validate the framework in a quantitative research setting. The extended analysis of the value-creating ecosystem could investigate the role of institutions and brand value propositions across levels.

Practical implications

Acknowledging their limited control over the brand co-creation process, tourism practitioners are offered step-by-step guidance to help shape a destination brand that may retain relevance in the tourists’ minds. Critical insights are provided into resource sharing between actors and subsequent responsibilities for a sustainable destination branding strategy.

Originality/value

The paper considers the significance of the various levels in the ecosystem and the underlying mechanisms of brand co-creation in a somewhat neglected branding domain.

Abstract

Purpose

In less than a decade to Sustainable Development Goals, the urban solid waste (USW) emanating from households, especially in developing countries, calls for concern. Several policies have been suggested and some implemented, but the challenges facing USW management remain, especially in developing nations. Past studies demonstrated that the fourth industrial revolution (4IR) technologies can be used to improve urban public services. The role of 4IR in mitigating the challenges of USW is yet to receive in-depth research in Nigeria. Thus, the study investigated 4IR role regarding mitigating the challenges facing USW.

Design/methodology/approach

Seven cities across Nigeria, including the Federal Capital Territory, were used as the study area to achieve the research objectives via a qualitative research design. Thirty-two semi-structured interviews were conducted from selected regulators, households, legislators, ICT experts, NGOs and waste managers. A thematic approach was adopted to analyse the collated data.

Findings

Findings group the USW challenges into five categories. The 4IR technologies can be used to manage USW; thus, they create an opportunity to integrate and promote sustainable clean cities.

Research limitations/implications

This study is confined to the 4IR role concerning mitigating the encumbrances facing USW in Nigeria and proffered feasible policies to enhance a sustainable healthy environment.

Practical implications

Proffered policy solutions will stir policymakers and construction practitioners to think outside the box and offer and better understand how 4IR technologies can be utilised to mitigate those challenges. The outcome will create sustainable clean cities as part of the implication contribution to the body of knowledge.

Originality/value

Evidence from the reviewed literature shows a paucity of literature focussed on 4IR roles in mitigating the encumbrances facing USW in Nigeria. Therefore, this study contributes to the existing research work on 4IR concerning its role in enhancing USW in Nigeria and, by extension, to other developing countries.
