Interestingly, LEED encourages termite treatments to buildings in order to avoid the structural degradation and fumigation that follows infestation (the former conflicts with LEED's interest in durability, while the latter is an affront to indoor air quality).
But our biggest protection against termites is our choice of materials. Our steel, glass and concrete house has none of the softwood lumber that is normally used as framing or trim in houses here. In theory, we won't have any materials that would attract termites. However, we've been warned that the foam insulation in our wall panels is susceptible to termite damage when they burrow their way toward food sources. We'll have to keep an eye on the lower edges of the panels around the perimeter of the house, and may have to treat them with a sodium borate repellent.
