A uniform and cohesive look adds simplicity to the overall aesthetic, supporting the minimalist design of this boathouse. The A5s is Glo’s slimmest profile, allowing for more glass, less frame, and wider sightlines. The concealed hinge creates a clean interior look while also providing a more energy-efficient air-tight window. The increased performance is also seen in the triple pane glazing used in both series. The windows and doors alike provide a larger continuous thermal break, multiple air seals, high-performance spacers, Low-E glass, and argon filled glazing, with U-values as low as 0.20. Energy efficiency and effortless minimalism create a breathtaking Scandinavian-style remodel.

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.

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.

Loudoun County's Leading Home Builder | 5x Best of Houzz

This passive solar addition transformed this nondescript ranch house into an energy efficient, sunlit, passive solar home. The addition to the rear of the building was constructed of compressed earth blocks. These massive blocks were made on the site with the earth from the excavation. With the addition of foam insulation on the exterior, the wall becomes a thermal battery, allowing winter sun to heat the blocks during the day and release that heat at night.
The house was built with only non toxic or natural
materials. Heat and hot water are provided by a 94% efficient gas boiler which warms the radiant floor. A new wood fireplace is an 80% efficient, low emission unit. With Energy Star appliances and LED lighting, the energy consumption of this home is very low. The addition of infrastructure for future photovoltaic panels and solar hot water will allow energy consumption to approach zero.

OVERVIEW
Set into a mature Boston area neighborhood, this sophisticated 2900SF home offers efficient use of space, expression through form, and myriad of green features.
MULTI-GENERATIONAL LIVING
Designed to accommodate three family generations, paired living spaces on the first and second levels are architecturally expressed on the facade by window systems that wrap the front corners of the house. Included are two kitchens, two living areas, an office for two, and two master suites.
CURB APPEAL
The home includes both modern form and materials, using durable cedar and through-colored fiber cement siding, permeable parking with an electric charging station, and an acrylic overhang to shelter foot traffic from rain.
FEATURE STAIR
An open stair with resin treads and glass rails winds from the basement to the third floor, channeling natural light through all the home’s levels.
LEVEL ONE
The first floor kitchen opens to the living and dining space, offering a grand piano and wall of south facing glass. A master suite and private ‘home office for two’ complete the level.

The goal of this project was to build a house that would be energy efficient using materials that were both economical and environmentally conscious. Due to the extremely cold winter weather conditions in the Catskills, insulating the house was a primary concern. The main structure of the house is a timber frame from an nineteenth century barn that has been restored and raised on this new site. The entirety of this frame has then been wrapped in SIPs (structural insulated panels), both walls and the roof. The house is slab on grade, insulated from below. The concrete slab was poured with a radiant heating system inside and the top of the slab was polished and left exposed as the flooring surface. Fiberglass windows with an extremely high R-value were chosen for their green properties. Care was also taken during construction to make all of the joints between the SIPs panels and around window and door openings as airtight as possible. The fact that the house is so airtight along with the high overall insulatory value achieved from the insulated slab, SIPs panels, and windows make the house very energy efficient. The house utilizes an air exchanger, a device that brings fresh air in from outside without loosing heat and circulates the air within the house to move warmer air down from the second floor. Other green materials in the home include reclaimed barn wood used for the floor and ceiling of the second floor, reclaimed wood stairs and bathroom vanity, and an on-demand hot water/boiler system. The exterior of the house is clad in black corrugated aluminum with an aluminum standing seam roof. Because of the extremely cold winter temperatures windows are used discerningly, the three largest windows are on the first floor providing the main living areas with a majestic view of the Catskill mountains.

The Port Ludlow Residence is a compact, 2400 SF modern house located on a wooded waterfront property at the north end of the Hood Canal, a long, fjord-like arm of western Puget Sound. The house creates a simple glazed living space that opens up to become a front porch to the beautiful Hood Canal.
The east-facing house is sited along a high bank, with a wonderful view of the water. The main living volume is completely glazed, with 12-ft. high glass walls facing the view and large, 8-ft.x8-ft. sliding glass doors that open to a slightly raised wood deck, creating a seamless indoor-outdoor space. During the warm summer months, the living area feels like a large, open porch. Anchoring the north end of the living space is a two-story building volume containing several bedrooms and separate his/her office spaces.
The interior finishes are simple and elegant, with IPE wood flooring, zebrawood cabinet doors with mahogany end panels, quartz and limestone countertops, and Douglas Fir trim and doors. Exterior materials are completely maintenance-free: metal siding and aluminum windows and doors. The metal siding has an alternating pattern using two different siding profiles.
The house has a number of sustainable or “green” building features, including 2x8 construction (40% greater insulation value); generous glass areas to provide natural lighting and ventilation; large overhangs for sun and rain protection; metal siding (recycled steel) for maximum durability, and a heat pump mechanical system for maximum energy efficiency. Sustainable interior finish materials include wood cabinets, linoleum floors, low-VOC paints, and natural wool carpet.

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.

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.
