The Stern Residence ‘Nautilus House’ is Michigan’s second USGBC LEED for Homes Platinum level certified whole house remodel. This ambitious project took a modest, unas- suming Cape Cod and completely transformed the home adding a new second floor and a dramatic curved roof above. The arced roof, besides being sculpturally striking, was intentionally designed to use the largest dimension of SIP panels manufactured, eliminating waste and maximizing utility, and provided an armature for mounting solar panels in the optimal location on the heavily wooded site. -James Haefner Photography

Winter Park’s first Net Zero Energy home is 4,565 square feet under air, but offers a staggering 8,000 square feet of overall living space. It is designed to fit in beautifully to the Winter Park neighborhood, but also to offer its owner a customized living space, all while drawing zero net energy from the City’s grid. Not only has the house been certified as Leed Platinum, but it also achieved several other certifications and has recently been qualified as the first department of Energy Challenge Home in the country as well. Rob Smith, of e2 Homes, an expert at Custom Home Building and Green Building practices, is proud to have been the builder chosen by the Wilson family to make their dreams of building a green home a reality. Rob understood their vision, and his nearly ten years of experience in Custom Home building gave them the confidence that he would deliver the construction excellence they were seeking.

Rodwin Architecture and Skycastle Homes Location: Boulder, CO, United States This LEED Platinum certified modern farmhouse is our first “regenerative home,” producing more energy than it consumes. This 3,900 s.f. custom home uses passive solar design, 10.2kW of solar photovoltaics, a ground source heat pump, double wall well-insulated exterior envelope, high performance doors and windows, to achieve a HERS negative 8 rating and Energy Star v.3.0 certification. The interior has low-VOC finishes and custom built-in FSC-certified wood and beetle kill pine cabinets throughout. The site is designed to be very low water use, incorporating permaculture and urban farming, with raised planting beds and a passive solar chicken coop/greenhouse. What makes this project special is its combination of extraordinary sustainability with conventionally attractive, cost-effective design tailored to the owner’s needs.

This 3,700 SF high performance, net-zero home built by Dwell Development achieved 5-Star Built Green certification. The home includes solar panels and an electric vehicle charging station. It also includes efficient heating and cooling through use of a Heat Recovery Ventilation System, which also provides the highest level of indoor air quality. The exterior walls of the house have a total thickness of 12”, which is then packed with blown-in cellulose insulation for a very efficient envelope, making it consistent and comfortable no matter the season. The floors are solid hardwood and polished concrete, while the tile and countertops throughout the house are made of recycled contents. The paint and grout were specifically chosen for the house to have no VOC’s.

ARCHITECTURE: Certificate of Merit
 PROJECT: A House for a Writer in Bohemia CLIENT: Private Owner, Czech Republic 
ARCHITECTURE FIRM: Front Studio Architects CONTRACTOR: Zikmund Hriste 
ENGINEERS: Inveko, Vitatech, Carvan Elektromontaze 
PHOTOGRAPHER: Jana Rackova DESCRIPTION: Located 30 miles north of Prague, Czech Republic, the House was to be a retreat, a private yet open space, full of light. The energy efficient 1200 sf residence is modern yet contextual, blending with the abandoned single-story structure for housing pigs and chickens on which it is built. JURY COMMENTS: This looks like a fun place to live and it is also laudable that it is a passive house. It is an honest, yet modest, project with an appropriate level of craft and detail.
