Only 29 hours were required to install this “off-the-shelf” Seattle prefab home that packs a plethora of energy efficient features. The project features passive design strategies to maximize natural daylighting and temperature control. The home incorporates ductless mini-split heating/cooling units—one in every room—that use inverter-driven compressors to provide exact control 100% of the time. Perhaps the greatest challenge of the project was trying to pack so many energy efficient features in under a budget. Not only does the bathroom feature NuHeat radiant floor mats but all water is heated with a GE Hybrid Heat Pump Water Heater, saving on heating expenses by around 67%. Minimalist vintage furnishings such as the CB2 dining table and Eames replica chairs give the interior a unique Scandinavian-meets-Pacific-Northwest flavor.
