                   What we can’t see and don’t know can hurt us—and our clients.

                   T       HE TOPIC OF HEALTHY HOMES AND BUILDINGS has
                           been around for a while, but the awareness of the problem
                           and what to do about it is being raised to a higher level
                           with recent ndings.
                             Having a healthy home environment is a core element
                   for every member of the building industry—architects designing
                   homes for people; builders building homes; and family members
                   concerned about their family’s health. This is an area that has been a
                   career-long interest of mine. In the past, it was more of a background
                   issue, but over time, research shows this to be increasingly important
                   as we gain a better understanding and additional knowledge of the
