Potential Use of Foamed Mortar (FM) for Thermal Upgrading of Chinese Traditional Hui-Style Residences

The Hui-style residence is an important architectural heritage of China. The hollow wall structures are widely used to build its exterior wall system. However, the thermal performance of the hollow wall is no longer able to meet the new energy-saving and environmental requirement. This article describes a laboratory study of the development of foamed mortar (FM), with the potential for use in thermal upgrading of the Hui-style hollow wall system without dramatically changing its traditional structure. The key early age, physical, mechanical and thermal properties were systematically measured. Two extended models were respectively developed to calculate compressive strength and thermal conductivity, as a function of porosity. Environment chamber test was also employed to investigate the effectiveness of this novel thermal upgrading approach and the results show that filling the voids with FM can effectively improve the overall thermal resistance of the hollow wall system by 44%, which is almost equal to the overall thermal resistance when using the more expensive commercial inorganic stucco system. In addition, the combination of these two methods yielded an overall thermal resistance of 0.701 m²·K/W, which is even higher than 0.67 m²·K/W for the code required in the hot summer/cold winter climate zone.     

al‐Khafaji reinterpreted: New insights on Umm an‐Nar monuments and settlement from Bat,Oman

Al‐Khafaji is a central and well‐known point on the early third millennium BC map of the UNESCO World Heritage Site of Bat, in the Sultanate of Oman. For years, Kasr al‐Khafaji (“Tower 1146”) has been understood as an Umm an‐Nar (ca. 2800–2000 BCE) monument standing amid a contemporary village. However, recent excavations by the Bat Archaeological Project (BAP) reveal that the entirety of the known site—monument(s) and settlement—is situated on an anthropogenic clay mound that elevated it meters above the surrounding landscape. This paper presents the results of BAP's recent excavations, emphasising the social spaces created by architecture of various functions and scales. It also considers the implications that this new interpretation of al‐Khafaji may have for how the relationship between Umm an‐Nar towers and settlement should be understood. The paper closes with a discussion of Umm an‐Nar tower function and social meaning, concluding that the Khafaji monument(s) likely served a symbolic and possibly performative role in Umm an‐Nar society that was perceived as separate from Umm an‐Nar settlement.     

Stitching Together the Fabric of Industrial Houses: Investigating the Origins and Development of Cotton Workers’ Accommodation in the Derwent Valley,Derbyshire

At the close of the 18th century, the first purpose-built industrial communities connected to mechanised cotton spinning were created in the Derwent Valley, Derbyshire. Across four sites at Cromford, Belper, Milford and Darley Abbey, three mill-owning families constructed a wide variety of purpose-built accommodation in order to house their growing workforces. This article uses a buildings-led approach to investigate the complex influences acting on the form and design of these houses. Through the analysis of historic building fabric, this research demonstrates that workers’ housing in the Derwent Valley comprised both innovative and traditional influences, reflecting the experimental character of early cotton manufacture. Ultimately, this research suggests that the array of approaches to house-building within the valley were the result of a highly nuanced interaction between the agenda, requirements and expectations of both occupant and patron.     

‘Why did they take him away?’ The theft of Neddy Larkin

Neddy Larkin, a Bundjalung man from New South Wales, Australia, was stolen from his grave and in 1891 sold to the Peabody Museum, Cambridge, MA. This paper uses the methodology and concepts outlined in Latour’s An Inquiry into Modes of Existence to chart Neddy Larkin’s transitions from kinsman to scientific data.     

Paving the way for new regional industrial paths: actors and modes of change in Scania’s games industry

ABSTRACT

Recent scholarly work has enhanced our understanding of how new path development activities are enabled or constrained by ‘regional environments’, made up of pre-existing industrial structures, knowledge organizations, support structures and institutional configurations. This paper moves beyond overly static views on regional environments. We develop a dynamic perspective by analysing conceptually and empirically how a constraining environment can be transformed into one that enables the development of new growth paths. The paper offers a typology of various modes of change, including layering, adaptation and novel application that are used by key actors to ‘manipulate’ the regional support structures to facilitate new regional industrial path development. The conceptual framework is applied to a case study of the digital games industry in the region of Scania, southern Sweden. Our findings suggest that the creation of a more enabling environment for the growth of the digital games industry has been the outcome of multi-scalar processes and combinations of various modes of change employed by a few key individuals operating in the newly emerging path.     

Brutalism Redux: Relational Monumentality and the Urban Politics of Brutalist Architecture

Brutalism is an architectural form that is experiencing somewhat of a revival of late. This revival focuses almost purely on its aesthetics, but there is an ethical dimension to Brutalism that often gets overlooked in these narratives. This paper therefore reanalyses the original concepts and ethics of brutalist architecture with a reaffirmation of the original triumvirate of brutalist ethics as articulated by Raynar Banham as monumentality, structural honesty and materials “as found”. The paper then articulates these through the literature on architectural affect to argue that brutalist ethics are continually “enacted” via a relational monumentality that brings the building and its inhabitants together in the practice of inhabitation. Using the case study of Robin Hood Gardens in London, the paper posits that a “brutalist politics” comes into light that can help catalyse a broader critique of contemporary neoliberalism.     

A history of conservation of built heritage sites of the Swahili Coast in Tanzania

The interaction between the Swahili Coast of the present-day Tanzanian coast and other parts of the Indian Ocean world dates back to the first millennium AD. This commercial communication resulted in the rise of several coastal city-states (stonebuilt towns), some of which date back to the tenth century. Unfortunately, some of these states started to collapse during the second half of the second millennium and the majority of them is in a ruinous state. These material remains, which according to the Tanzania’s Antiquities Act of 1964 deserve legal protection, have not been studied comprehensively mainly to establish their conservation history. The current article addresses this problem, and by analysing documents, it establishes the conservation history of monuments and historic buildings of the Swahili Coast in Tanzania. Research results indicate that some built heritage sites started decaying during the fourteenth century AD. Because of recognising the importance of these built heritage sites, communities of the region embarked on strategies to care these built heritage sites. This observation contradicts the European conventional wisdom maintaining that, in Africa, conservation of built heritage sites such as monuments and historic buildings began in the nineteenth century and was propagated by European colonialists.
