Memory and Agency in Ancient China offers a novel perspective on China's material culture. The volume explores the complex 'life histories' of selected objects, whose trajectories as ginle objects ('biographies') and object types ('lineages') cut across both temporal and physical space. The essays, written by a team of international scholars, analyse the objects in an effort to understand how they were shaped by the constraints of their social, political and aesthetic contexts, just as they were also guided by individual preference and capricious memory. They also demonstrate how objects were capable of effecting change. Ranging chronologically from the Neolithic to the present, and spatially from northern to southern mainland China and Taiwan, this book highlights the varied approaches that archaeologists and art historians use when attempting to reconstruct object trajectories. It also showcases the challenges they face, particularly with the unearthing of objects from archaeological contexts that, paradoxically, come to represent the earliest known point of their 'post-recovery lives'.

Throughout the world, there is an increasing interest in ecological design of buildings, and natural ventilation has proved to be the most efficient low-energy cooling technique. Its practical application, however, is hindered by the lack of information on the complex relationship between the building and its urban environment. In this book, a team of experts provide first-hand information and tools on the efficient use of natural ventilation in urban buildings. Key design principles are explained, enabling readers to decide on the best solution for natural ventilation of buildings, taking into account climate and urban context.In the initial sketches, architects need answers to open problems such as 'what kind of solution to adopt' and 'how to modify existing strategies to exploit the potential of the site'. This book formalizes the multi-criteria analysis of candidate solutions based on quantitative and qualitative estimation of the driving forces (wind and buoyancy), as well as of the barriers induced by the urban environment (wind speed reduction, noise and pollution) and gives a methodology for optimal design of openings. The book is accompanied by downloadable resources, containing software for assessing the potential of a given site, estimating wind speed and dimensioning the openings for natural ventilation. The methodologies and tools are tested, self-contained and user friendly.About the editorsThe editors, Cristian Ghiaus and Francis Allard, are affiliated with the University of La Rochelle, France.
