The protection of our environment is at the heart of our approach to architectural design.
ECA has, from its foundation in 1965, sought an architecture in which the environmental design forms a vital part of a holistic approach to building production. We collaborate with the best environmental designers and engineers to maintain our commitment to sustainable design and research. An Environmental Management System combines the remits, targets and programme for our approach to sustainable work - in both how we work and the projects we design. We have ISO 14001 accreditation which serves to enforce our commitment to a sustainable lifestyle.
