Adapting to the challenges of rapid urban growth and societal change will require mechanisms for efficient transitioning to an embedded resilience. This has become central to the exploration of methods for achieving truly sustainable urban growth. However, while transitioning and resilience are useful descriptors, they can be abstract or conflicting ideals and their meanings obscured by a lack of concrete examples, both being barriers to many planning objectives. In this paper, we hold a lens over key issues in transitioning to resilience in urban areas by outlining emerging challenges that may offer directions towards operationalising how cities might transition to a more resilient future, while ensuring that communities are at the center of the process. The emerging and challenging areas – geospatial ICT, green infrastructure planning, novel design using collaborative responses, climate planning, limiting urban sprawl and short-circuit economic approaches – are explored as viable facets for devising and sustaining urban transition strategies. We conclude with a discussion on the need for developing a synergistic approach in practice to facilitate transition

The paper presents the results of a laboratory investigation on the hygric properties of five hemp insulation materials commercially available in the UK. The hemp fibre content varies between 30% and 95% in the total fibre content of the insulation materials examined. The adsorption–desorption isotherm, moisture buffer value, vapour diffusion resistance factor and water absorption coefficient were determined for the insulation materials investigated. The results showed that the hygric properties of the hemp insulation materials could vary widely depending on the constituents and fibrous structure. The considerable differences noted in the hygric properties of the insulation materials examined could potentially influence their hygrothermal performance as part of a building thermal envelope

An in situ experiment on a full-scale timber frame test building was carried out to study the hygrothermal performance of wood-hemp composite insulation in timber frame wall panels with and without a vapour barrier. The heat transfer properties and the likelihood of mould growth and condensation in the panels were compared. Step changes in the internal relative humidity were performed to explore the effects of high, normal and low internal moisture loads on the wall panels. No significant difference in the average equivalent thermal transmittance (U-values) between the panels with and without a vapour barrier was observed. The average equivalent U-values of the panels were close to the U-values calculated from the manufacturers’ declared thermal conductivity values of the insulation. The likelihood of condensation was higher at the interface of the wood-hemp insulation and the oriented strand board (OSB) in the panel without a vapour barrier. In terms of the parametric assessment of the mould germination potential, the relative humidity, the temperature and the exposure conditions in the insulation-OSB interfaces of the panel without a vapour barrier were found to be more favourable to the germination of mould spores. Nonetheless, when the insulations were dismantled, no mould was visually detected
