The Building Designers Association of Australia (BDAA) is the national representative body for the building design and energy assessor profession, representing more than 3,000 individual members and over 8,500 professionals across their practices. As the only truly national association of its kind, the BDAA provides a unified voice for designers across every state and territory.

Voted Australia’s number one most trusted association, the BDAA brings together a diverse and highly skilled membership including building designers, architects, interior designers, engineers, builders, energy assessors, and students. This collective expertise forms a powerful national network influencing the design and delivery of projects across the country.

The BDAA does not just represent the industry, it actively leads and shapes it. Working closely with Federal and State governments, the Association contributes to policy, standards, and reform while advocating for better outcomes across the built environment.

Through national programs, industry events, and education initiatives including the International Sustainability and Energy Efficiency Summit, the BDAA provides a platform for innovation, collaboration, and professional excellence.
