Staying in the loop: identifying performance gaps

Feedback loops identify what is going routinely wrong in buildings and give valuable insight into how future building performance can be improved. Susie Diamond and William Box explain the concept, and discuss how it could be applied to ventilation

Hot and bothered: Zehnder overheating survey

The risk of overheating in buildings is growing significantly as temperatures rise, but a new survey by CIBSE Journal and Zehnder Group UK shows that mitigating the risk is not always a priority in design even though respondents say it’s a hot issue. David Blackman reports

Low carbon, high safety: fire engineering and embodied carbon

The embodied carbon impact of fire safety measures is relatively unknown. Arup’s Grete Wilson and Dr Emma McIntyre have created a roadmap to establish how engineers can create low carbon designs without compromising fire safety

Exploring the non-visual effects of lighting

The 2023 Jean Heap Bursary has helped fund an advanced eye-tracking headset, which is allowing lighting designer and researcher Simone Bonavia to assess how lighting affects people’s non-visual functions

The urban emergency: addressing environmental quality

Designers must take a holistic approach to the urban environment, say members of the UK Urban Environmental Quality working group, who explain how elements such as wind, water and the urban form can be addressed to optimise air quality and thermal comfort
