Crafting Critical Heritage Discourses into Interactive Exhibition Design

This paper argues how a more reflective design practice that embraces critical discourses can transform interactive exhibition design and therefore the museum visiting experience. Four framing arguments underpin our exhibition design making: the value of materiality, visiting as an aesthetic experience, challenging the authorized voice, and heritage as a process. These arguments were embodied through design, art and craft practice into one interactive exhibition at a house museum. We draw from our design process discussing the implications that adopting an approach informed by critical heritage debates has on exhibition design and suggest three sensitizing concepts (polyvocal narratives, dialogical interaction, interweaving time and space) bridging the practice of interactive exhibition design and critical heritage theory

Environmental performance of miscanthus-lime lightweight concrete using life cycle assessment:Application in external wall assemblies

This is the final version. Available from Elsevier via the DOI in this record. In the UK context, miscanthus is a potential alternative perennial crop for the development of bio-based building materials. This paper presents the environmental benefits of using miscanthus shives in lightweight blocks and their potential application in wall assemblies. A systemic life cycle assessment (LCA) is carried out for miscanthus-lime blocks, and the effects of binder type and binder content are discussed. The environmental performance-based analysis reveals that miscanthus blocks can capture 135 kg CO eq/m for an assumed 100-years life period. The impact analysis using the University of Leiden, institute of environmental science (CML) baseline (v4.4) method shows that 75% of the greenhouse gas emissions are attributable to the production of mineral binders. A reduction of binder to aggregate ratio from 2.0 to 1.5 reduces greenhouse gas emissions by 32.9%. The use of 10 wt% mineral additions can potentially stabilise blocks while having little effect on their overall environmental impacts. The environmental profiles of wall systems incorporating miscanthus-lime blocks have been evaluated in this this study. Combining miscanthus blocks with fired clay bricks enables a potential low carbon retrofitting technique for the current stock of residential buildings in the UK. Timber-framed system filled with miscanthus blocks enables a carbon storage of ~97.3 kg CO eq/m , which presents a potential carbon offsetting strategy in new-build dwellings. Consideration should be given to the potential negative impacts related to agricultural activities for the production of miscanthus shives. The largest negative environmental impact was ozone layer depletion, where a relative difference of 12.8% was recorded between miscanthus timber-framed wall and a typical solid wall insulated with mineral wool. It appears that miscanthus-lime composites can substantially improve the environmental profile of wall assemblies and sustainability be applied in existing uninsulated masonry walls or incorporated in timber- framed new-build houses.Engineering and Physical Sciences Research Council (EPSRC)Natural Environment Research Council (NERC)NERC GW4+ Doctoral Training Partnership studentshi
