The boundaries between the many disciplines involved in the process of design, supply, installation, testing and operation of building façades is becoming blurred. For buildings to achieve high energy efficiency and create a comfortable environment for occupants, there must be an appropriate dialogue between architects, façade engineers, building services engineers, structural engineers and contractors. The Society of Façade Engineering brings these people together in a forum where they can work together to advance knowledge and practice in facade engineering, promote good practice and ensure that today's increasingly complex building façades meet the many and varying performance criteria. In particular, it addresses the complex issues in building physics of thermal insulation, ventilation, lighting, solar control, and acoustics. The Society of Façade Engineering was formed in 2004 as a joint initiative of CIBSE, IStructE and the RIBA. It is governed by a Council drawn from among its members and administered by CIBSE. The Society acts as an axis for those involved in the façade industry to determine the credentials of members and as a surety for those seeking to employ them. Membership is open to all individuals who have an involvement in façade engineering.
