Lincoln Farmhouse
LEED-H Platinum, Net-Positive Energy
OVERVIEW. This LEED Platinum certified modern farmhouse ties into the cultural landscape of Lincoln, Massachusetts - a town known for its rich history, farming traditions, conservation efforts, and visionary architecture. The goal was to design and build a new single family home on 1.8 acres that respects the neighborhood’s agrarian roots, produces more energy than it consumes, and provides the family with flexible spaces to live-play-work-entertain. The resulting 2,800 SF home is proof that families do not need to compromise on style, space or comfort in a highly energy-efficient and healthy home.
CONNECTION TO NATURE. The attached garage is ubiquitous in new construction in New England’s cold climate. This home’s barn-inspired garage is intentionally detached from the main dwelling. A covered walkway connects the two structures, creating an intentional connection with the outdoors between auto and home.
FUNCTIONAL FLEXIBILITY. With a modest footprint, each space must serve a specific use, but also be flexible for atypical scenarios. The Mudroom serves everyday use for the couple and their children, but is also easy to tidy up to receive guests, eliminating the need for two entries found in most homes. A workspace is conveniently located off the mudroom; it looks out on to the back yard to supervise the children and can be closed off with a sliding door when not in use. The Away Room opens up to the Living Room for everyday use; it can be closed off with its oversized pocket door for secondary use as a guest bedroom with en suite bath.
NET POSITIVE ENERGY. The all-electric home consumes 70% less energy than a code-built house, and with measured energy data produces 48% more energy annually than it consumes, making it a 'net positive' home. Thick walls and roofs lack thermal bridging, windows are high performance, triple-glazed, and a continuous air barrier yields minimal leakage (0.27ACH50) making the home among the tightest in the US. Systems include an air source heat pump, an energy recovery ventilator, and a 13.1kW photovoltaic system to offset consumption and support future electric cars.
ACTUAL PERFORMANCE. -6.3 kBtu/sf/yr Energy Use Intensity (Actual monitored project data reported for the firm’s 2016 AIA 2030 Commitment. Average single family home is 52.0 kBtu/sf/yr.)
o 10,900 kwh total consumption (8.5 kbtu/ft2 EUI)
o 16,200 kwh total production
o 5,300 kwh net surplus, equivalent to 15,000-25,000 electric car miles per year. 48% net positive.
WATER EFFICIENCY. Plumbing fixtures and water closets consume a mere 60% of the federal standard, while high efficiency appliances such as the dishwasher and clothes washer also reduce consumption rates.
FOOD PRODUCTION. After clearing all invasive species, apple, pear, peach and cherry trees were planted. Future plans include blueberry, raspberry and strawberry bushes, along with raised beds for vegetable gardening. The house also offers a below ground root cellar, built outside the home's thermal envelope, to gain the passive benefit of long term energy-free food storage.
RESILIENCY. The home's ability to weather unforeseen challenges is predictable - it will fare well. The super-insulated envelope means during a winter storm with power outage, heat loss will be slow - taking days to drop to 60 degrees even with no heat source. During normal conditions, reduced energy consumption plus energy production means shelter from the burden of utility costs. Surplus production can power electric cars & appliances. The home exceeds snow & wind structural requirements, plus far surpasses standard construction for long term durability planning.

This LEED Platinum certified house reflects the homeowner's desire for an exceptionally healthy and comfortable living environment, within a traditional neighborhood.
INFILL SITE. The family, who moved from another area of Wellesley, sought out this property to be within walking distance of the high school and downtown area. An existing structure on the tight lot was removed to make way for the new home. 84% of the construction waste, from both the previous structure and the new home, was diverted from a landfill. ZED designed to preserve the existing mature trees on the perimeter of the property to minimize site impacts, and to maintain the character of the neighborhood as well as privacy on the site.
EXTERIOR EXPRESSION. The street facade of the home relates to the local New England vernacular. The rear uses contemporary language, a nod to the family’s Californian roots, to incorporate a roof deck, solar panels, outdoor living space, and the backyard swimming pool. ZED’s careful planning avoided to the need to face the garage doors towards the street, a common syndrome of a narrow lot.
THOUGHTFUL SPACE. Homes with dual entries can often result in duplicate and unused spaces. In this home, the everyday and formal entry areas are one and the same; the front and garage doors share the entry program of coat closets, mudroom storage with bench for removing your shoes, and a laundry room with generous closets for the children's sporting equipment. The entry area leads directly to the living space, encompassing the kitchen, dining and sitting area areas in an L-shaped open plan arrangement. The kitchen is placed at the south-west corner of the space to allow for a strong connection to the dining, sitting and outdoor living spaces. A fire pit on the deck satisfies the family’s desire for an open flame while a sealed gas fireplace is used indoors - ZED’s preference after omitting gas burning appliances completely from an airtight home. A small study, with a window seat, is conveniently located just off of the living space. A first floor guest bedroom includes an accessible bathroom for aging visitors and can be used as a master suite to accommodate aging in place.
HEALTHY LIVING. The client requested a home that was easy to clean and would provide a respite from seasonal allergies and common contaminants that are found in many indoor spaces. ZED selected easy to clean solid surface flooring throughout, provided ample space for cleaning supplies on each floor, and designed a mechanical system with ventilation that provides a constant supply of fresh outdoor air. ZED selected durable materials, finishes, cabinetry, and casework with low or no volatile organic compounds (VOCs) and no added urea formaldehyde.
YEAR-ROUND COMFORT. The home is super insulated and air-tight, paired with high performance triple-paned windows, to ensure it is draft-free throughout the winter (even when in front of the large windows and doors). ZED designed a right-sized heating and cooling system to pair with the thermally improved building enclosure to ensure year-round comfort. The glazing on the home maximizes passive solar gains, and facilitates cross ventilation and daylighting.
ENERGY EFFICIENT. As one of the most energy efficient houses built to date in Wellesley, the home highlights a practical solution for Massachusetts. First, the building enclosure reduces the largest energy requirement for typical houses (heating). Super-insulation, exceptional air sealing, a thermally broken wall assembly, triple pane windows, and passive solar gain combine for a sizable heating load reduction. Second, within the house only efficient systems consume energy. These include an air source heat pump for heating & cooling, a heat pump hot water heater, LED lighting, energy recovery ventilation, and high efficiency appliances. Lastly, photovoltaics provide renewable energy help offset energy consumption. The result is an 89% reduction in energy use compared to a similar brand new home built to code requirements.
RESILIENT. The home will fare well in extreme weather events. During a winter power outage, heat loss will be very slow due to the super-insulated and airtight envelope– taking multiple days to drop to 60 degrees even with no heat source. An engineered drainage system, paired with careful the detailing of the foundation, will help to keep the finished basement dry. A generator will provide full operation of the all-electric house during a power outage.
OVERALL. The home is a reflection of the family goals and an expression of their values, beautifully enabling health, comfort, safety, resilience, and utility, all while respecting the planet.

Situated on a 3.5 acre, oak-studded ridge atop Santa Barbara's Riviera, the Greene Compound is a 6,500 square foot custom residence with guest house and pool capturing spectacular views of the City, Coastal Islands to the south, and La Cumbre peak to the north. Carefully sited to kiss the tips of many existing large oaks, the home is rustic Mediterranean in style which blends integral color plaster walls with Santa Barbara sandstone and cedar board and batt.
Landscape Architect Lane Goodkind restored the native grass meadow and added a stream bio-swale which complements the rural setting. 20' mahogany, pocketing sliding doors maximize the indoor / outdoor Santa Barbara lifestyle by opening the living spaces to the pool and island view beyond. A monumental exterior fireplace and camp-style margarita bar add to this romantic living. Discreetly buried in the mission tile roof, solar panels help to offset the home's overall energy consumption. Truly an amazing and unique property, the Greene Residence blends in beautifully with the pastoral setting of the ridge while complementing and enhancing this Riviera neighborhood.

The compact footprint and efficient, cockpit-like, interior spaces serve their functions well without gratuity. A rooftop photovoltaic solar panel system offsets power consumption, and careful attention to natural day lighting and ventilation combined with a high efficiency radiant floor heating system help make the house a modest energy user. photo credit - John Ellis

Rather than starting with an outcome in mind, this 1,400 square foot residence began from a polemic place - exploring shared conviction regarding the concentrated power of living with a smaller footprint. From the gabled silhouette to passive ventilation, the home captures the nostalgia for the past with the sustainable practices of the future.
While the exterior materials contrast a calm, minimal palette with the sleek lines of the gabled silhouette, the interior spaces embody a playful, artistic spirit. From the hand painted De Gournay wallpaper in the master bath to the rugged texture of the over-grouted limestone and Portuguese cobblestones, the home is an experience that encapsulates the unexpected and the timeless.

ZeroEnergy Design (ZED) created this modern home for a progressive family in the desirable community of Lexington.
Thoughtful Land Connection. The residence is carefully sited on the infill lot so as to create privacy from the road and neighbors, while cultivating a side yard that captures the southern sun. The terraced grade rises to meet the house, allowing for it to maintain a structured connection with the ground while also sitting above the high water table. The elevated outdoor living space maintains a strong connection with the indoor living space, while the stepped edge ties it back to the true ground plane. Siting and outdoor connections were completed by ZED in collaboration with landscape designer Soren Deniord Design Studio.
Exterior Finishes and Solar. The exterior finish materials include a palette of shiplapped wood siding, through-colored fiber cement panels and stucco. A rooftop parapet hides the solar panels above, while a gutter and site drainage system directs rainwater into an irrigation cistern and dry wells that recharge the groundwater.
Cooking, Dining, Living. Inside, the kitchen, fabricated by Henrybuilt, is located between the indoor and outdoor dining areas. The expansive south-facing sliding door opens to seamlessly connect the spaces, using a retractable awning to provide shade during the summer while still admitting the warming winter sun. The indoor living space continues from the dining areas across to the sunken living area, with a view that returns again to the outside through the corner wall of glass.
Accessible Guest Suite. The design of the first level guest suite provides for both aging in place and guests who regularly visit for extended stays. The patio off the north side of the house affords guests their own private outdoor space, and privacy from the neighbor. Similarly, the second level master suite opens to an outdoor private roof deck.
Light and Access. The wide open interior stair with a glass panel rail leads from the top level down to the well insulated basement. The design of the basement, used as an away/play space, addresses the need for both natural light and easy access. In addition to the open stairwell, light is admitted to the north side of the area with a high performance, Passive House (PHI) certified skylight, covering a six by sixteen foot area. On the south side, a unique roof hatch set flush with the deck opens to reveal a glass door at the base of the stairwell which provides additional light and access from the deck above down to the play space.
Energy. Energy consumption is reduced by the high performance building envelope, high efficiency mechanical systems, and then offset with renewable energy. All windows and doors are made of high performance triple paned glass with thermally broken aluminum frames. The exterior wall assembly employs dense pack cellulose in the stud cavity, a continuous air barrier, and four inches exterior rigid foam insulation. The 10kW rooftop solar electric system provides clean energy production. The final air leakage testing yielded 0.6 ACH 50 - an extremely air tight house, a testament to the well-designed details, progress testing and quality construction. When compared to a new house built to code requirements, this home consumes only 19% of the energy.

Project Year:2016
This LEED-certified project was a substantial rebuild of a 1960's home, preserving the original foundation to the extent possible, with a small amount of new area, a reconfigured floor plan, and newly envisioned massing. The design is simple and modern, with floor to ceiling glazing along the rear, connecting the interior living spaces to the landscape. The design process was informed by building science best practices, including solar orientation, triple glazing, rain-screen exterior cladding, and a thermal envelope that far exceeds code requirements.
