BAC/A+P is an architectural firm rooted in the belief that historic preservation values equal the best of green building practices. Our firm’s work demonstrates that the artistic, scientific and cultural aspects of remaking and greening historic and existing buildings are crucial to a sustainable future. The firm founder, Barbara Campagna, a preservation architect with 25 years experience has been at the forefront of the green building movement for over ten years as a leading voice for the integration of historic preservation and green building practices. We believe that reusing what we have – buildings, landscapes, communities – is the best way to make the biggest impact in controlling climate change. From changing out your light bulbs to renovating an existing building or neighborhood to LEED Platinum standards – it’s all important and BAC/A+P offers consulting services to guide our clients through all the solutions.
