When it comes to building green, perhaps branding is everything. La Plate-forme Maison Passive, a Belgian organization supporting the sustainable approach to architecture known as "Passive House," recently released a mildly risqué video that makes passive seem quite active indeed. While the more buttoned-up LEED (Leadership in Environmental and Energy Design) has been the standard reference point in the U.S since the early ‘90s, the Passive House movement—started at virtually the same time in Germany but targeting the residential sector—has lagged behind in wide-scale adoption stateside. But that may be about to change.

LEED certification is based largely on a preemptive checklist of eco bells and whistles and is scaled up for commercial and institutional projects, but a passive structure must demonstrate measurable performance results that prove its efficiency at producing nearly as much energy as it consumes—something much more achievable at the residential scale.
