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.

WHAT MAKES VILLA TERRA GREEN?
1. Rammed Earth and PISE Walls
Beyond it’s beautiful qualities and “Old World” look, the rammed earth and PISE walls (pneumatically impacted stabilized earth) drastically reduce the use of trees for the initial wall framing lumber. And because this “Earth Structure” will far outlast any wood frame building, trees are again saved many times over, creating the foundation for the true model of sustainability. We have created a house that will essentially last forever, instead of having to be rebuilt every 50 to 75 years.
The 18” thick PISE walls and concrete floors also provide thermal mass, an integral part of the passive solar design of the house. These features help keep the house naturally cooler in summer and retaining heat in winter, greatly reducing the heating and cooling loads and energy use.
2. High Content Fly Ash Concrete Foundation
Use of high content (25%) fly ash (industrial waste byproduct) in place of Portland Cement results in reduction of energy consumption and green house gas emissions associated with Portland cement production (second only to petroleum in terms of carbon dioxide emissions).
3. Reclaimed Plumbing Fixtures
All lavatory sinks and tubs were bought from salvage yards (tub is reportedly from the Jack Benny house in Hollywood). Reclaimed Carrara marble fountain has been made into the powder room sink.
4. Natural Daylighting
Use of numerous skylights and high transom windows to reduce electrical lighting loads during the day. Natural daylighting also has documented benefits on mood, productivity, and enjoyment of the space.
5. Photo Voltaic Solar Panels
Use of PV solar electric generation system to reduce electrical grid consumption, and bi-directional meter sends power back to the grid when it is needed most, on hot summer afternoons.
6. Hydronic Radiant Heat Floor
Use of hydronic radiant floor heating system saves energy, is more efficient for residential heating, is more comfortable for inhabitants, and promotes superior indoor air quality over forced air systems.
7. Natural/Passive Ventilation
Use of operable skylights operable high windows and ceiling fans, creates a natural convection current, thereby eliminating the need for an air conditioning system.
8. Passive Solar Design
Use of extensive east and south facing glass, proper overhangs, high interior mass, deciduous grape vines on appropriately placed trellises, to passively heat the home in winter, and protect the house from unnecessary heat gain in summer.
9. Reclaimed Lumber
- Douglas fir ceiling beams reclaimed from the Town & Country Village Shopping Center (now Santana Row) in San Jose.
- Douglas fir ceiling decking reclaimed from the 118 year old Notre Dame High School in downtown San Jose. TJI joists reclaimed from the “Millenium Man” movie set in Alameda used for floor and roof framing. Redwood ceiling beams reclaimed from a Los Altos cabana/trellis.
10. Extensive Use of Other Reclaimed Materials Two antique reclaimed European stone fireplace mantles grace the family room and master bedroom fireplaces. Interior doors with glass knobs reclaimed from the original house located at the property. Two large terraces utilize used brick salvaged from at least 15 different locations. Courtyard fountain is tiled using recycled and restored ceramic tiles from a 1928 California Colonial house in Los Altos. Cabinet lumber from original house used for closet shelving. Plywood from crates that the windows and doors were delivered in were used to create garage shear walls. Foundation forms were salvaged and rip cut for use as interior stud walls. Garage doors were salvaged from a remodel project in Mountain View.
11. Ground Source Heat Pump
- Ground source heat pump uses geothermal energy to heat the house and domestic water, greatly reducing natural gas and fossil fuel consumption.
12. Low VOC Paint
Clay Plaster Wall Finishes VOC-free interior paint and stain finishes promotes healthy indoor air quality, reduces exacerbation of respiratory ailments such as asthma and lung cancer. Extensive use of American Clay Plaster integral color wall finish eliminates need for painted walls.
13. High Efficiency Windows
Use of energy efficient dual pane thermal glazing with “Low e” coating at all doors and windows reduces heat gain in summer and heat loss in winter, cutting energy use.
14. Engineered Structural Lumber
Extensive use of engineered lumber for structural framing and sheathing reduces cutting of old growth forests, and encourages use of “crop lumber”.
15. FSC Certified Mill Work
Extensive use of FSC (Forest Stewardship Council) certified sustainable lumber products for cabinetry, hardwood flooring, trim, etc. further protects the environment through third party monitoring and certification of the entire supply chain.
16. Cotton Insulation
Formaldehyde-free cotton insulation made from recycled blue jeans used extensively for attic insulation.

This new home takes advantage of a beautiful hilltop site. The outdoor spaces function as an extension of the house and support the family’s casual, sports-oriented lifestyle. The design, for a family of seven, provides spaces for individual privacy and family gatherings.
The design challenge was to incorporate a number of sustainable features into the design. The south-facing roof is integrated with a 5-kilowatt photovoltaic system, generating electricity for the home and furnishing emergency backup power. The heating is exclusively radiant with high efficiency boilers partially burning biofuel. Measures taken to produce an efficient building envelope include a drainage plane behind the siding, spray foam insulation, and high performance, insulated window glass.

This historic home and coach house in a landmark district on Astor Street was built in the late 1800’s. Originally designed as an 11,000sf single family residence, the home
was divided into nine apartments in the 1960’s and had fallen into disrepair. The new owners purchased the property with a vision to convert the building back to single
family residence for their young family.
The design concept was to restore the limestone exterior to its original state and reconstruct the interior into a home with an open floor plan and modern amenities for entertaining and family living, incorporating vintage details from the original property whenever possible. Program requirements included five bedrooms, all new bathrooms, contemporary kitchen, salon, library, billiards room with bar, home office, cinema, playroom, garage with stacking car lifts, and outdoor gardens with all new landscaping.
The home is unified by a grand staircase which is flooded with natural light from a glass laylight roof. The first level includes a formal entry with rich wood and marble finishes,
a walnut-paneled billiards room with custom bar, a play room, and a separate family entry with mudroom. A formal living and dining room with adjoining intimate salon are located on the second level; an addition at the rear of the home includes a custom deGiulio kitchen and family room. The third level master suite includes a marble bathroom, dressing room, library, and office. The fourth level includes the family bedrooms and a guest suite with a terrace and views of Lake Michigan. The lower level houses a custom cinema. Sustainable elements are seamlessly integrated throughout and include renewable materials, high-efficiency mechanicals and thermal envelope, restored original mahogany windows with new high-performance low-E glass, and a green roof.


The house design takes full advantage of the local climate such that a net zero energy building is obtained. This was done by employing a highly efficient building envelope and incorporating passive solar gains (Photo: Grey Crawford)

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 modern green home offers both a vacation destination on Cape Cod near local family members and an opportunity for rental income.
FAMILY ROOTS. A West Coast couple living in the San Francisco Bay Area sought a permanent East Coast vacation home near family members living on Cape Cod. As academic professionals focused on sustainability, they sought a green, energy efficient home that was well-aligned with their values. With no green homes available for sale on Cape Cod, they decided to purchase land near their family and build their own.
SLOPED SITE. Comprised of a 3/4 acre lot nestled in the pines, the steeply sloping terrain called for a plan that embraced and took advantage of the slope. Of equal priority was optimizing solar exposure, preserving privacy from abutters, and creating outdoor living space. The design accomplished these goals with a simple, rectilinear form, offering living space on the both entry and lower/basement levels. The stepped foundation allows for a walk-out basement level with light-filled living space on the down-hill side of the home. The traditional basement on the eastern, up-hill side houses mechanical equipment and a home gym. The house welcomes natural light throughout, captures views of the forest, and delivers entertainment space that connects indoor living space to outdoor deck and dining patio.
MODERN VISION. The clean building form and uncomplicated finishes pay homage to the modern architectural legacy on the outer Cape. Durable and economical fiber cement panels, fixed with aluminum channels, clad the primary form. Cedar clapboards provide a visual accent at the south-facing living room, which extends a single roof plane to cover the entry porch.
SMART USE OF SPACE. On the entry level, the “L”-shaped living, dining, and kitchen space connects to the exterior living, dining, and grilling spaces to effectively double the home’s summertime entertainment area. Placed at the western end of the entry level (where it can retain privacy but still claim expansive downhill views) is the master suite with a built-in study. The lower level has two guest bedrooms, a second full bathroom, and laundry. The flexibility of the space—crucial in a house with a modest footprint—emerges in one of the guest bedrooms, which doubles as home office by opening the barn-style double doors to connect it to the bright, airy open stair leading up to the entry level. Thoughtful design, generous ceiling heights and large windows transform the modest 1,100 sf* footprint into a well-lit, spacious home. *(total finished space is 1800 sf)
RENTAL INCOME. The property works for its owners by netting rental income when the owners are home in San Francisco. The house especially caters to vacationers bound for nearby Mayo Beach and includes an outdoor shower adjacent to the lower level entry door. In contrast to the bare bones cottages that are typically available on the Cape, this home offers prospective tenants a modern aesthetic, paired with luxurious and green features. Durable finishes inside and out will ensure longevity with the heavier use that comes with a rental property.
COMFORT YEAR-ROUND. The home is super-insulated and air-tight, with mechanical ventilation to provide continuous fresh air from the outside. High performance triple-paned windows complement the building enclosure and maximize passive solar gain while ensuring a warm, draft-free winter, even when sitting close to the glass. A properly sized air source heat pump offers efficient heating & cooling, and includes a carefully designed the duct distribution system to provide even comfort throughout the house. The super-insulated envelope allows us to significantly reduce the equipment capacity, duct size, and airflow quantities, while maintaining unparalleled thermal comfort.
ENERGY EFFICIENT. The building’s shell and mechanical systems play instrumental roles in the home’s exceptional performance. The building enclosure reduces the most significant energy glutton: heating. Continuous super-insulation, thorough air sealing, triple-pane windows, and passive solar gain work together to yield a miniscule heating load. All active energy consumers are extremely efficient: an air source heat pump for heating and cooling, a heat pump hot water heater, LED lighting, energy recovery ventilation (ERV), and high efficiency appliances. The result is a home that uses 70% less energy than a similar new home built to code requirements.
OVERALL. The home embodies the owners’ goals and values while comprehensively enabling thermal comfort, energy efficiency, a vacation respite, and supplementary income.
