In addition to beefing up the thermal envelope and adding a ton of insulation, we also helped design this array of photovoltaic (solar) panels to reduce the home's energy consumption.

Photo credit: Michael Moran/OTTO. We designed this home with a flat roof so that you can barely see the large arrays of PVs (solar panels). If you look very carefully, you can see the outline of the panels above the eaves, but they're almost impossible to spot. The design concept for this home is that you wouldn't see anything on top of the roofs, but the truth is that the photovoltaics contribute significantly to the home's energy efficiency. The home is LEED certified and our clients tell us it's comfortable and cozy throughout the year.
