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

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. LEVEL TWO The second floor includes another open concept living, dining, and kitchen space, with kitchen sink views over the green roof. A full bath, bedroom and reading nook are perfect for the children. LEVEL THREE The third floor provides the second master suite, with separate sink and wardrobe area, plus a private roofdeck. ENERGY The super insulated home features air-tight construction, continuous exterior insulation, and triple-glazed windows. The walls and basement feature foam-free cavity & exterior insulation. On the rooftop, a solar electric system helps offset energy consumption. WATER Cisterns capture stormwater and connect to a drip irrigation system. Inside the home, consumption is limited with high efficiency fixtures and appliances.

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.
