BuroHappold Engineering is a professional services firm providing engineering consultancy, design, planning, project management and consulting services for all aspects of buildings, infrastructure and the environment, with its head office in Bath, Somerset. It was founded in 1976, by Sir Edmund Happold in Bath in the southwest of England when he left Ove Arup and Partners to take up a post at the University of Bath as Professor of Architecture and Engineering Design.Originally working mainly on projects in the Middle East, the firm now operates worldwide and in almost all areas of engineering for the built environment, with offices in seven countries.

Coated woven fabrics have been used in state-of-the-art structures for over 40. years yet their design is not codified and relies heavily on experience and precedent. The mechanical behaviour of fabrics is non-linear and time dependent, with assumed or highly simplified material properties commonly used for analysis. The shape of a tensile fabric canopy is fundamental to its ability to resist all applied loads in tension. Increasingly Architects are moving away from conventional fabric forms, utilising lower levels of curvature and new materials.This paper considers the importance of material properties and structural geometry in the design and analysis of tensile fabric structures. Three typical tensile forms are examined: the conic, hyperbolic paraboloid ('hypar') and barrel vault. Whilst the barrel vault demonstrates the expected result that minimally curved structures are inefficient and highly sensitive to changes in materials properties, the hypar exhibits more complex behaviour with the structural action varying dramatically with changes in geometry, material properties and patterning (fabrication) direction. For conic structures the feasible geometries that can be attained using 'soap film' form-finding is established, which combined with checks for ponding provide a range of geometric parameters for the efficient design of conic structures. © 2012 Elsevier Ltd.

Structural and Multidisciplinary Optimization
Computational modeling software facilitates the creation of any surface geometry imaginable, but it is not always obvious how to create an efficient grid shell structure on a complex surface. This paper presents a design tool for synthesis of optimal grid structures, using a Multi-Objective Genetic Algorithm to vary rod directions over the surface in response to two or more load cases. A process of grid homogenization allows the tool to be rapidly applied to any grid structure consisting of a repeating unit cell, including quadrilateral, triangular and double layer grids. Two case studies are presented to illustrate the successful execution of the optimization procedure. © 2009 Springer-Verlag. Source

Renewable and Sustainable Energy Reviews
This paper presents a comprehensive review of all significant research applying computational optimisation to sustainable building design problems. A summary of common heuristic optimisation algorithms is given, covering direct search, evolutionary methods and other bio-inspired algorithms. The main summary table covers 74 works that focus on the application of these methods to different fields of sustainable building design. Key fields are reviewed in detail: envelope design, including constructions and form; configuration and control of building systems; renewable energy generation; and holistic optimisations of several areas simultaneously, with particular focus on residential and retrofit. Improvements to the way optimisation is applied are also covered, including platforms and frameworks, algorithmic comparisons and developments, use of meta-models and incorporation of uncertainty. Trends, including the rise of multi-objective optimisation, are analysed graphically. Likely future developments are discussed. © 2013 Elsevier Ltd. Source

A climate control system includes a closed vessel containing a phase change material for absorbing heat from or emitting heat to an environment in which the system is intended to be arranged. The closed vessel also contains a solid heat conducting medium for facilitating heat transfer within the vessel.

Abstracts are not currently available in GtR for all funded research. This is normally because the abstract was not required at the time of proposal submission, but may be because it included sensitive information such as personal details.
