About Archemy Consulting Ltd | Sustainable buildings and neighbourhoods

Integrated design, at its best, places human activity in a healthy and connected relationship with the natural world in which it belongs. This is also known as environmental design or sustainable design.

DavidDavid Rousseau is an original in the field of integrated, sustainable design. Trained in engineering, environmental studies, architecture and urban planning, he has decades of experience with healthy buildings, advanced energy efficiency, water and waste recycling systems, green materials and construction. He has guided the design of many landmark green building and neighbourhood projects and led the development of green building performance assessment tools and programs for municipalities and the private sector. He also writes and teaches.

David comes to the field from a design and construction background and has never moved far from the “hands on”. He still spends a lot of time building, gardening and tinkering. He especially likes making beautiful and useful things out of surplus or recycled items.


Hope cannot be said to exist, nor can it be said not to exist.
It is just like the roads across the earth.
For actually there were no roads to begin with,
But when many people pass one way a road is made.
