Located in an existing neighborhood of post-war houses, Skidmore Passivhaus merges contemporary design with the highest level of energy efficiency. Providing a true live / work condition, two separate buildings address the program requirements while creating a unique indoor / outdoor space between. High levels of insulation, extremely airtight construction (tested at .32ach50), high performing triple glazed european windows, and a super-efficient heat recovery ventilator allow the structure to meet the stringent requirements of the German Passivhaus standard. Generous amounts of south facing glazing (.5 shgc) maximize the solar gains for most of the year, while motorized exterior aluminum shades can be lowered to block unwanted summer heat gain resulting in extremely comfortable temperatures year round. An extensive green roof helps manage all stormwater on site, while a roof mounted 4.32 kW PV array provides enough electricity to result in a near net zero and truly sustainable building.
