A new modern farmhouse has been created in Ipswich, Massachusetts, approximately 30 miles north of Boston. The new house overlooks a rolling landscape of wetlands and marshes, close to Crane Beach in Ipswich. The heart of the house is a freestanding living pavilion, with a soaring roof and an elevated stone terrace. The terrace provides views in all directions to the gentle, coastal landscape. A cluster of smaller building pieces form the house, similar to farm compounds. The entry is marked by a 3-story tower, consisting of a pair of study spaces on the first two levels, and then a completely glazed viewing space on the top level. The entry itself is a glass space that separates the living pavilion from the bedroom wing. The living pavilion has a beautifully crafted wood roof structure, with exposed Douglas Fir beams and continuous high clerestory windows, which provide abundant natural light and ventilation. The living pavilion has primarily glass walls., with a continuous, elevated stone terrace outside. The roof forms a broad, 6-ft. overhang to provide outdoor space sheltered from sun and rain. In addition to the viewing tower and the living pavilion, there are two more building pieces. First, the bedroom wing is a simple, 2-story linear volume, with the master bedroom at the view end. Below the master bedroom is a classic New England screened porch, with views in all directions. Second, the existing barn was retained and renovated to become an integral part of the new modern farmhouse compound. Exterior and interior finishes are straightforward and simple. Exterior siding is either white cedar shingles or white cedar tongue-and-groove siding. Other exterior materials include metal roofing and stone terraces. Interior finishes consist of custom cherry cabinets, Vermont slate counters, quartersawn oak floors, and exposed Douglas fir framing in the living pavilion. The main stair has laser-cut steel railings, with a pattern evocative of the surrounding meadow grasses. The house was designed to be highly energy-efficient and sustainable. Upon completion, the house was awarded the highest rating (5-Star +) by the Energy Star program. A combination of “active” and “passive” energy conservation strategies have been employed. On the active side, a series of deep, drilled wells provide a groundsource geothermal heat exchange, reducing energy consumption for heating and cooling. Recently, a 13-kW solar power system with 40 photovoltaic panels has been installed. The solar system will meet over 30% of the electrical demand at the house. Since the back-up mechanical system is electric, the house uses no fossil fuels whatsoever. The garage is pre-wired for an electric car charging station. In terms of passive strategies, the extensive amount of windows provides abundant natural light and reduces electric demand. Deep roof overhangs and built-in shades are used to reduce heat gain in summer months. During the winter, the lower sun angle is able to penetrate into living spaces and passively warm the concrete subfloor. Radiant floors provide constant heat with thermal mass in the floors. Exterior walls and roofs are insulated 30-40% greater than code requirements. Low VOC paints and stains have been used throughout the house. The high level of craft evident in the house reflects another key principle of sustainable design: build it well and make it last for many years!

The new owners of this West Village Manhattan townhouse knew that gutting an historically significant building would be a complex undertaking. They were admirers of Turett's townhouse renovations elsewhere in the neighborhood and brought his team on board to convert the multi-unit structure into a single family home. Turett's team had extensive experience with Landmarks, and worked closely with preservationists to anticipate the special needs of the protected facade. The TCA team met with the city's Excavation Unit, city-appointed archeologists, preservationists, Community Boards, and neighbors to bring the owner's original vision - a peaceful home on a tree-line street - to life. Turett worked with adjacent homeowners to achieve a planted rear-yard design that satisfied all interested parties, and brought an impressive array of engineers and consultants aboard to help guarantee a safe process. Turett worked with the owners to design a light-filled house, with landscaped yard and terraces, a music parlor, a skylit gym with pool, and every amenity. The final designs include Turett's signature tour-de-force stairs; sectional invention creating overlapping volumes of space; a dramatic triple-height steel-and-glass elevation; extraordinary acoustical and thermal insulation as part of a highly energy efficient envelope.

Who says green and sustainable design has to look like it? Designed to emulate the owner’s favorite country club, this fine estate home blends in with the natural surroundings of it’s hillside perch, and is so intoxicatingly beautiful, one hardly notices its numerous energy saving and green features. Durable, natural and handsome materials such as stained cedar trim, natural stone veneer, and integral color plaster are combined with strong horizontal roof lines that emphasize the expansive nature of the site and capture the “bigness” of the view. Large expanses of glass punctuated with a natural rhythm of exposed beams and stone columns that frame the spectacular views of the Santa Clara Valley and the Los Gatos Hills. A shady outdoor loggia and cozy outdoor fire pit create the perfect environment for relaxed Saturday afternoon barbecues and glitzy evening dinner parties alike. A glass “wall of wine” creates an elegant backdrop for the dining room table, the warm stained wood interior details make the home both comfortable and dramatic. The project’s energy saving features include: - a 5 kW roof mounted grid-tied PV solar array pays for most of the electrical needs, and sends power to the grid in summer 6 year payback! - all native and drought-tolerant landscaping reduce irrigation needs - passive solar design that reduces heat gain in summer and allows for passive heating in winter - passive flow through ventilation provides natural night cooling, taking advantage of cooling summer breezes - natural day-lighting decreases need for interior lighting - fly ash concrete for all foundations - dual glazed low e high performance windows and doors Design Team: Noel Cross+Architects - Architect Christopher Yates Landscape Architecture Joanie Wick – Interior Design Vita Pehar - Lighting Design Conrado Co. – General Contractor Marion Brenner – Photography

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.

Photo credit: Scott McDonald @ Hedrich Blessing 7RR-Ecohome: The design objective was to build a house for a couple recently married who both had kids from previous marriages. How to bridge two families together? The design looks forward in terms of how people live today. The home is an experiment in transparency and solid form; removing borders and edges from outside to inside the house, and to really depict “flowing and endless space”. The house floor plan is derived by pushing and pulling the house’s form to maximize the backyard and minimize the public front yard while welcoming the sun in key rooms by rotating the house 45-degrees to true north. The angular form of the house is a result of the family’s program, the zoning rules, the lot’s attributes, and the sun’s path. We wanted to construct a house that is smart and efficient in terms of construction and energy, both in terms of the building and the user. We could tell a story of how the house is built in terms of the constructability, structure and enclosure, with a nod to Japanese wood construction in the method in which the siding is installed and the exposed interior beams are placed in the double height space. We engineered the house to be smart which not only looks modern but acts modern; every aspect of user control is simplified to a digital touch button, whether lights, shades, blinds, HVAC, communication, audio, video, or security. We developed a planning module based on a 6-foot square room size and a 6-foot wide connector called an interstitial space for hallways, bathrooms, stairs and mechanical, which keeps the rooms pure and uncluttered. The house is 6,200 SF of livable space, plus garage and basement gallery for a total of 9,200 SF. A large formal foyer celebrates the entry and opens up to the living, dining, kitchen and family rooms all focused on the rear garden. The east side of the second floor is the Master wing and a center bridge connects it to the kid’s wing on the west. Second floor terraces and sunscreens provide views and shade in this suburban setting. The playful mathematical grid of the house in the x, y and z axis also extends into the layout of the trees and hard-scapes, all centered on a suburban one-acre lot. Many green attributes were designed into the home; Ipe wood sunscreens and window shades block out unwanted solar gain in summer, but allow winter sun in. Patio door and operable windows provide ample opportunity for natural ventilation throughout the open floor plan. Minimal windows on east and west sides to reduce heat loss in winter and unwanted gains in summer. Open floor plan and large window expanse reduces lighting demands and maximizes available daylight. Skylights provide natural light to the basement rooms. Durable, low-maintenance exterior materials include stone, ipe wood siding and decking, and concrete roof pavers. Design is based on a 2' planning grid to minimize construction waste. Basement foundation walls and slab are highly insulated. FSC-certified walnut wood flooring was used. Light colored concrete roof pavers to reduce cooling loads by as much as 15%. 2x6 framing allows for more insulation and energy savings. Super efficient windows have low-E argon gas filled units, and thermally insulated aluminum frames. Permeable brick and stone pavers reduce the site’s storm-water runoff. Countertops use recycled composite materials. Energy-Star rated furnaces and smart thermostats are located throughout the house to minimize duct runs and avoid energy loss. Energy-Star rated boiler that heats up both radiant floors and domestic hot water. Low-flow toilets and plumbing fixtures are used to conserve water usage. No VOC finish options and direct venting fireplaces maintain a high interior air quality. Smart home system controls lighting, HVAC, and shades to better manage energy use. Plumbing runs through interior walls reducing possibilities of heat loss and freezing problems. A large food pantry was placed next to kitchen to reduce trips to the grocery store. Home office reduces need for automobile transit and associated CO2 footprint. Plan allows for aging in place, with guest suite than can become the master suite, with no need to move as family members mature.

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 renovated brick rowhome in Boston’s South End offers a modern aesthetic within a historic structure, creative use of space, exceptional thermal comfort, a reduced carbon footprint, and a passive stream of income. DESIGN PRIORITIES. The goals for the project were clear - design the primary unit to accommodate the family’s modern lifestyle, rework the layout to create a desirable rental unit, improve thermal comfort and introduce a modern aesthetic. We designed the street-level entry as a shared entrance for both the primary and rental unit. The family uses it as their everyday entrance - we planned for bike storage and an open mudroom with bench and shoe storage to facilitate the change from shoes to slippers or bare feet as they enter their home. On the main level, we expanded the kitchen into the dining room to create an eat-in space with generous counter space and storage, as well as a comfortable connection to the living space. The second floor serves as master suite for the couple - a bedroom with a walk-in-closet and ensuite bathroom, and an adjacent study, with refinished original pumpkin pine floors. The upper floor, aside from a guest bedroom, is the child's domain with interconnected spaces for sleeping, work and play. In the play space, which can be separated from the work space with new translucent sliding doors, we incorporated recreational features inspired by adventurous and competitive television shows, at their son’s request. MODERN MEETS TRADITIONAL. We left the historic front facade of the building largely unchanged - the security bars were removed from the windows and the single pane windows were replaced with higher performing historic replicas. We designed the interior and rear facade with a vision of warm modernism, weaving in the notable period features. Each element was either restored or reinterpreted to blend with the modern aesthetic. The detailed ceiling in the living space, for example, has a new matte monochromatic finish, and the wood stairs are covered in a dark grey floor paint, whereas the mahogany doors were simply refinished. New wide plank wood flooring with a neutral finish, floor-to-ceiling casework, and bold splashes of color in wall paint and tile, and oversized high-performance windows (on the rear facade) round out the modern aesthetic. RENTAL INCOME. The existing rowhome was zoned for a 2-family dwelling but included an undesirable, single-floor studio apartment at the garden level with low ceiling heights and questionable emergency egress. In order to increase the quality and quantity of space in the rental unit, we reimagined it as a two-floor, 1 or 2 bedroom, 2 bathroom apartment with a modern aesthetic, increased ceiling height on the lowest level and provided an in-unit washer/dryer. The apartment was listed with Jackie O'Connor Real Estate and rented immediately, providing the owners with a source of passive income. ENCLOSURE WITH BENEFITS. The homeowners sought a minimal carbon footprint, enabled by their urban location and lifestyle decisions, paired with the benefits of a high-performance home. The extent of the renovation allowed us to implement a deep energy retrofit (DER) to address air tightness, insulation, and high-performance windows. The historic front facade is insulated from the interior, while the rear facade is insulated on the exterior. Together with these building enclosure improvements, we designed an HVAC system comprised of continuous fresh air ventilation, and an efficient, all-electric heating and cooling system to decouple the house from natural gas. This strategy provides optimal thermal comfort and indoor air quality, improved acoustic isolation from street noise and neighbors, as well as a further reduced carbon footprint. We also took measures to prepare the roof for future solar panels, for when the South End neighborhood’s aging electrical infrastructure is upgraded to allow them. URBAN LIVING. The desirable neighborhood location allows the both the homeowners and tenant to walk, bike, and use public transportation to access the city, while each charging their respective plug-in electric cars behind the building to travel greater distances. OVERALL. The understated rowhouse is now ready for another century of urban living, offering the owners comfort and convenience as they live life as an expression of their values.

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.

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. photography by Frank Paul Perez

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.
