EWS CAMDEN TO APPROVE EYE HOSPITAL DESIGN Camden Council is expected to grant planning permission for a new adaptive building that will bring patient-centred eye care, research and education under one roof in Londons emerging Knowledge Quarter. A team including Aecom, architects Penoyre & Prasad and interiors specialist White Arkitekter is designing Oriel, a joint initiative the design team and is providing building services, civil and structural engineering, as well as sustainability and other specialist services. Vallance report highlights importance of ventilation A report commissioned by the governments Infection resilient environments: buildings that keep us healthy and safe CIBSE publishes Covid-19 air cleaning technology guidance New guidance on air cleaning technologies has been published by CIBSE. Covid-19: air cleaning technologies allows users to assess the variety of air cleaning devices currently marketed for the removal of SARS-CoV-2, and to discover which, if any, will reduce transmission risk in a given space effectively. The guidance, available at www.cibse. org/knowledge, says scientific evidence suggests air cleaners could be part of the solution to minimising risks in certain situations, but are not a solution that reduces all risks. The primary building systems measure to reduce far field (>2m) airborne spread indoors is increased ventilation, it states. The document also includes a Relative Exposure Risk Calculator, an Excel tool that lets users assess relative risk of exposure to Covid-19 in a given space by changing values for dimensions, number of occupants, breathing rate, respiratory activity occupation time and ventilation provision. CIBSE has updated its Covid-19: ventilation guidance, addressing the use of CO2 monitors and the change in restrictions. Read more from Dr Shaun Fitzgerald on page 20.
