Building Alternatives Inc (BAI) is a consulting engineering firm licensed in BC, Alberta, Saskatchewan, Manitoba, Ontario and the North-West Territories & Nunavut. BAI actively participates in educational programs both at university and college level institutions as well as through professional and trade associations. Tim spent two years as the coordinator of the Alternative Village at the University of Manitoba, which was founded by Building Alternatives principal, Dr. Kris Dick. BAI is active in applied research, working together with academic institutions on projects to improve our quantitative knowledge of pre-industrial building materials and their behaviour in the Canadian climate, collaborating between the Alternative Village at the U of M and with researchers at Queen’s University, University of New Brunswick and others.
BAI specializes in engineering design using low-embodied energy, low carbon emission materials such as wood, earth, stone, straw, clay, hemp, and lime. This engineering design includes the techniques with which these materials are combined and assembled, and incorporates responsible and appropriate current technologies such as air barrier membranes and geosynthetics that allow new applications of the older, time tested materials. Tim's research interests include earthen construction, timber & cellulose building, design for de-constructability, energy and material efficiency and sustainability in the built environment.
