HEALTHCARE | GUIDANCE Working towards net zero in hospital facilities CIBSE Healthcare Group is helping make buildings safer, energy efficient and more comfortable. Group chair Frank Mills FCIBSE outlines key upcoming reports and guidance C IBSE Healthcare Group is working with the NHS in the UK to improve patient healing experiences and to provide efficient, effective, resilient environments for patients, staff and visitors. It also gives support to CIBSE members across the world, and works with professional technical societies to disseminate knowledge and develop solutions to the challenges facing the healthcare sector. The group has liaised on ASHRAE TC 9.6 Healthcare and ASHRAE Std 170, Ventilation of Healthcare Premises, and is helping introduce natural ventilation into ASHRAE guidance and its review of air change rates in medical facilities. In Europe, the group is working with REHVA to develop a net-zero hospital guide, which is expected to be published in 2020 as a joint REHVA/ASHRAE publication. NHS project A major NHS Improvements project is reviewing the technical guidance on the heating, ventilation and air conditioning of hospitals Hospital Technical Memorandum (HTM) 03 and the group is giving input via the NHS Working Panel. This is developing a consultation document to be an issue of high importance and the group continues to promote widescale application of CIBSE Guidance TM13 and HSE ACOP documents. Ensuring members get CPD updates will help with the control of legionella see CIBSE courses and other CPD offerings at www.cibse.org/knowledge The group is also considering innovative healthcare solutions and their engineering requirements, as well as their impact on the healing and wider public environments. Biophilia issued for public review in September. At an open meeting at HQ last month, the group considered a range of issues: recirculation v full fresh air; application of UV air sterilisation; air filtration; methods of air flow laminar, displacement, mixing; and selection of supply, extract, recirculation air terminals to achieve desired air movements. The NHS is keen to reduce energy costs and carbon emissions, and work towards netzero targets. The group will give useful input on steps to achieve these aspirations. Legionella prevention Legionella outbreaks in hospitals remain Planting green landscapes with flowers, trees and water features, to support healing and staff productivity through natural ambience known as biophilia is receiving much attention, and we must ensure building services for healthy plant growth and clean water systems are installed and operating. Green walls are a relatively new and particular green feature. They clean air via their biology and include a hydroponic system to supply water to the vertical layers of planting, and drainage, which takes away excess water from a low-level gulley. The group is also developing strategies for hospitals in response to the Hackitt review, with better emphasis on competencies, ongoing training, CPD and CIBSE events to achieve excellent outcomes and full and proper project commissioning, completion and handover.
