Abstract

Purpose

The purpose of this paper is to examine the details of the air mass flow and aerodynamical phenomena across a channel containing a large vertical axis wind turbine. The considered model reproduces as closely as possible the real assembly of the Sistan-type wind-mill whose top is open. The technical results of this work could be used for the restoration and operation of this assembly whose historical and architectural values are recognized.

Design/methodology/approach

Several inlet velocities into the channel are considered, taking into account the possible local wind resources. Calculations corresponding to Reynolds number varying between 8×105 and 4×106 are made by means of the finite volume method and turbulence is treated with the realizable k-ε model. The mesh consists of a fixed part associated to the contour of the channel, interfaced with a moving one linked to the turbine itself, equipped with nine partly filled wings.

Findings

The relative pressure and velocity fields are presented for various dynamic and static conditions. Calculation results clearly show that the vortex phenomena present in some cases are not a source of degradation of the wind turbine’s aerodynamical performances, given its location, intensity and rotation direction. Particular attention is devoted to the air mass flow and its distribution between the inlet and the outlet sections of the channel.

Originality/value

The present work provides technical information useful to consider the restoration and modernization of this installation whose architecture and technical performance are very interesting. This survey complements a previous one examining the aerodynamical phenomena occurring in a modified version of this assembly with a closed top channel.

Abstract

Purpose

This study aims to determine and consolidate the multi-scale components that inform anticipatory action for resilience; propose a conceptual framework for the collaborative and holistic design, delivery and management of resilience at both the macro and micro scale; and test the efficacy of the framework to deliver sustainable (sustained) resilience.

Design/methodology/approach

A conceptual framework was proposed by consolidating what was learnt from literature review. Case studies were then used to explore the efficacy of the framework to deliver resilience. The applicability of the specific measures was also examined to determine the extent by which they support anticipatory action and resilience capacity.

Findings

It was found that a combination of active, latent, evolving and to some extent improvised yet integrated solutions can support anticipatory flood resilience at the micro, meso and macro scale, as well as the physical and social domains.

Research limitations/implications

Socio-physical resilience improves when policy makers, designers, planners and engineers work together to deliver anticipatory solutions prior to a natural disaster. Further, findings confirm that resilience can be achieved in both new and existing urban contexts.

Social implications

The multi-scale, integrated strategies can inform anticipatory practices, which, in turn, may reduce social vulnerability during and after natural events such as flooding.

Originality/value

This work lays the foundation for further theoretical and practical work on socio-spatial resilience and provides the learning-based structure within which policy makers, planners and architects can administer interventions for the practical delivery of planning-scale and building-level resilience.

Abstract

Purpose

The purpose of this paper is twofold: first, to investigate the flood impact on a detached dwelling based on physical attributes related to the positioning, form and orientation of the house, and second, to investigate the effectiveness of property-level protection (PLP) to mitigate the direct structural damage of the house and the degree of floodwater ingress within the house.

Design/methodology/approach

The methods included modelling and simulation within the ANSYS Fluent® computational fluid dynamics software. Flooding scenarios with constrained parameters using theoretical modelling methods/tools were used to test the research hypotheses. Therefore, the results obtained will match the what-if scenarios considered if/based on the standard equations and assumptions made in the idealised model.

Findings

It was found that the position, orientation and form of an individual dwelling with brick and block construction informs the impact of the applied pressure on the structure and water ingress. Increase in pressure on the structure was noted from 0.3 m. All examined PLP mitigated the risk of structural damage if applied in consideration with other interventions e.g. mortar sealing. The use of non-return valves could potentially increase the pressure on the structure, but was also found to be effective in reducing water ingress. Findings should be considered in conjunction with the assumptions and exceptions of this study.

Research limitations/implications

The limitations of this study are that the findings are based on an idealised model of a single detached house, with no landscape obstruction to the watercourse. This mathematical approach concerned with developing the normative models may therefore not fully describe the real-world complex phenomena. But it provides the first vision and an objective basis to answer the questions under study, and to propose usable outputs. Flooding caused from internal sources (e.g. bursting of pipes, roof leaks) or seepage from the ground and moisture through the walls were excluded. Building content was not modelled.

Practical implications

Common property-level flood interventions are typically tested to mitigate water ingress to the house. This study extends this approach to include the prevention of structural damage to the external walls; this can help to avoid the indiscriminate use of property-level flood prevention solutions without full understanding of their degree of effectiveness or impact on the building’s structural integrity. This study is practically significant because it provides outputs and means to examine which intervention(s) are better for delivering flood protection to a standard brick/block detached house type. This knowledge is highly beneficial for relevant stakeholders who can use it to deliver effective property-level flooding resilience measures.

Originality/value

The study provides useful insights for property owners and building professionals to explore suitable, cost-effective single property-level protection against flooding. Furthermore, the effective implementation of interventions can be used to achieve a customised, “fit for purpose” resilience retrofit.

Abstract

Purpose

The purpose of this paper is threefold; to investigate the potential impact of energy conservation policies and legislation on building design; examine energy conservation practices in the building industry; and identify associated barriers to an integrated low energy architectural design process.

Design/methodology/approach

A survey of UK architectural design practices was conducted to assess the impact of current energy conservation policies and legislation on current building design, and ascertain architects' views on the associated barriers and incentives to implementing and sustaining energy conservation strategies in their projects.

Findings

Results reveal that building design is affected by existing legislation but often not by policies. Additionally, there is a lack of incentives for the building industry to adopt and implement low energy design strategies that are outlined in existing policies and guidance. Furthermore, results identify a need for increased awareness of the available energy saving technologies.

Research limitations/implications

Architects are the first point of contact for driving more energy efficient design and conservation strategies. Therefore, this study was confined to a cross section of their opinions of energy conservation within the UK building industry.

Practical implications

The study is useful for those interested in the current levels of implementation of low energy design strategies and the recommendations for the future of the energy conservation and building design in the UK.

Originality/value

The study of energy conservation and building design provides insights into current environmental design practices; and identifies problems for the implementation of effective and integrated low energy building design process. The content should be of interest to architects, as it highlights the current level of implementation of energy conservation measures in building design.

Abstract

Purpose

This paper aims to focus on hybrid projects as a type of building adaptation work. It seeks to discuss the hybrid building design process in subsets of information and resulting decisions by highlighting the relationship between them. It also aims to present a conceptual framework which was developed by refining, or customising the RIBA Plan of Work.

Design/methodology/approach

Field theory formed the theoretical basis for the approach to mapping the hybrid project process. The conceptual framework itself evolved from a comprehensive literature review, case studies and a practice survey. In total, 11 design and construction professionals evaluated the framework and their comments and feedback are also discussed.

Findings

The discussion presents an approach which can be used to manage the delivery of hybrid projects, although it was found that the proposed framework can be applied to a wider spectrum of construction projects.

Research limitations/implications

The evaluation of the framework was limited by the number of participants involved and the limited client representation.

Originality/value

The paper makes an original contribution by further exploring an increasingly relevant area of construction activity; building adaptations. Although the research focused specifically on the design‐specific stages of hybrid project delivery, findings contribute towards process improvement by emphasising the need for early information acquisition, early and precise definition of design intent, and collaborative design decision making. These three factors contribute highly to client/user satisfaction (value) and effective project delivery.

Abstract

Purpose

The purpose of this paper is to report on partial findings of a research project on post‐occupancy design in school projects. It provides a brief review of key factors, and major players in post‐occupancy processes.

Design/methodology/approach

Subsequent to literature review for the research, the primary data was obtained from a steering group (stakeholder forum) comprising of a sample of primary and secondary school representatives, local authorities and building professionals. Following the data collection, visits were arranged to the selected schools, and local councils and semi‐structured interviews with school and council authorities were carried out. At the same time, research meeting and directed studies were held to best explore the applications for devising the toolkit. Simulated and real cases for making decisions in post‐occupancy design were selected to devise a model‐base to test out the applicability of the devised prototype of the toolkit.

Findings

This study provided clarification on the post‐occupancy performance and practicable expectations of major parties in school projects with special reference to the development stage of the proposed toolkit. The qualitative and quantitative data collected, confirmed that a real‐time updateable support system for decisions is required for making the most reasonable decisions where multi‐criteria/multi‐agent decision is inevitable. The principles of co‐creation of knowledge and value, as suggested in manufacture and service industries, were investigated to inform the underlying design platform for the toolkit. The decision support systems for multi‐criteria decision making processes were also established so that the toolkit can take a full account of the achievements in this area.

Originality/value

The paper highlights the complexities involved in the post‐occupancy decision processes in school projects. Also, the pressing need for a system to assist in streamlining the information flow (particularly upwards, from the schools to the LA) and management of knowledge to facilitate design decisions is identified. The decision processes need to be more integrated, collaborative and inclusive. It also acknowledges that decision making in post‐occupancy processes, is an evolving process. The main contribution of this paper however, remains to be how the collaborative processes were streamlined for all the stakeholders to work together and co‐create knowledge and value to devise a platform.

Abstract

Purpose

This paper aims to review the impact of design and specification decisions for major works during post‐occupancy processes; the routine maintenance and management of school premises. It also seeks to explore the relationship between the main stakeholders and how this impacts decision‐making and the post‐occupancy operation of school buildings.

Design/methodology/approach

In addition to a literature review, qualitative data were also obtained through a focus group; a steering group. The steering group consisted of stakeholders tasked with delivering and managing school premises in the Sussex County.

Findings

The findings contribute to understanding the impact of design decisions on post‐occupancy processes in schools. A basic model is also presented as a guide for requirements and decision mapping in post‐occupancy design decision processes in schools.

Research limitations/implications

The study was conducted with the participation of a representative sample of stakeholders. There may be the need to investigate the issues further in a localised context before detailed solutions are proposed.

Practical implications

The paper reports findings based on the needs, requirements, and preferences of the stakeholders as well as the opportunities and constraints to improving the quality of design processes which in turn will improve post occupancy processes.

Originality/value

The paper highlights the complexity of design decision‐making in schools, presents the viewpoint of stakeholders, and proposes a basic model to ensure performance for post‐occupancy processes to inform the next stage of the research.
