Structural safety and environmental sustainability are major factors in investment decisions for building systems, but are rarely considered simultaneously. Recent research efforts have redressed this by developing assessment methodologies and technical solutions for integrated energy efficiency and seismic performance. These studies are typically...
Preprint
Glass is one of the UK’s eight energy-intensive industries. As such, it is under scrutiny to decouple growth in production from greenhouse gas (GHG) emissions. The energy input associated with glass production can be reduced by using recycled glass (cullet) in new glass production, which enables lower furnace operating temperatures and reduces dema...
Chapter
Façade design is an inherently interdisciplinary process and requires the concurrent integration of a variety of design criteria from different sources. Knowledge-based engineering (KBE), the management and digitalization of engineering knowledge into ready-to-use software applications, provides a means to address this challenge. This chapter first...
Article
Reuse and high-value recycling have a pivotal role to play in reducing waste and minimising carbon emissions in the built environment. Design strategies for such recovery methods have yet to be fully established in the façade industry. Meanwhile, stringent regulations, aimed at reducing operational carbon emissions of buildings and improving other...

Connections between load-bearing glass components play a major role in terms of the structural integrity and aesthetics of glass applications. Recently, a new type of adhesive connection, known as embedded laminated glass connections, has been developed where a metallic insert is embedded within a laminated glass unit by means of transparent polyme...
Article
Building occupants interact frequently with façades. These interactions simultaneously affect several domains of the indoor environment (visual, thermal, air quality and acoustic) and occupant perception, as well as the energy performance of the façades. Yet this multi-domain relationship between façade and occupant is not well understood. This gap...
Article
Testing of novel facade technologies with human volunteers is essential for improving occupant interaction with novel dynamic facade systems and to increase satisfaction with its modulation of light, sound, heat and mass transfer between the outdoor and indoor environments. In the past 10 years, there have been noticeable attempts to develop chambe...

Reduced embodied emissions can be found through the responsible sourcing of resources and re-use of materials...
Conference Paper
Full-text available
In recent decades, there has been increased attention to reduce the operational energy performance of buildings. Stringent legislation on building energy performance has stimulated façade design to evolve to serve numerous functions and meet complex technical requirements. This has in part been achieved by an increase in the use of materials, proce...
Article
Thermally tempered glass fails into small and blunt pieces upon fracture, and therefore is the product of choice when a degree of safety is required from a monolithic glass panel. The characteristic fracture pattern is the result of residual stresses in the glass that are induced during the tempering process and released during fracture. Previous r...
Article
Full-text available
