A Classic Barn for a Classic Car Enthusiast

elevation of classic car garageAre you one of those people who owns a classic car and longs for an appropriate place to keep your dream machine? That was the impetus behind one car enthusiast’s desire to physically connect his passion for collectible automobiles to his existing 1930s Delaware residence. The owner, who has an existing garage for his family cars, tools around in a ‘76 Triumph TR6 and hopes to acquire more vintage cars once his new timber frame car barn is completed next month. The result will be an architecturally true barn and connector addition that can drive home, literally, his automotive passion.

The barn and connector were designed by Patrick McDonough, of John Milner Architects, to integrate and reflect the style of the existing main house while adding to the majesty and proportion of the façade.

classic car garage elevationBensonwood was hired by the owner/builder, a repeat client, to fabricate and raise the free-standing timber frame barn shell. The lengthy connector joining the house with the barn will be site-built by Dewson Construction Company, a Delaware-based general contractor and construction management firm.

The car barn, with four bays and an epoxy-painted concrete floor to showcase the vehicles, will be a traditional design, with a single, 28-foot-long glulam girder to achieve a post-free opening to the shed bump at the rear of the building. Roof trusses on either end of the barn will have straight bottom chords, with three arched glulam bottom chords on the trusses in between, defining the vaulted space. The structure includes a central king post with decorative and structural steel reinforcement plate custom fabricated by Bob Taylor of Alstead, NH. A multi-purpose loft with ladder at one end of the structure will add useful square footage to the plan.classic car garage interior rendering

CAD DRAWING vintage auto barnTo integrate the architectural style of the barn with the main house, an eight-sided “lantern” cupola will be stick-built atop the barn by a local company to match the cupola on the main house. In addition to its unifying aesthetic, the copula will allow in natural light to illuminate the timber frame interior and future car collection. Dewson Construction will then finish the barn with a brick exterior to match the main house.

The classic car barn, currently in fabrication at our Blackjack Crossing facilities in Walpole, NH, is slotted for a September 15 raising, with the complete weather-tight shell installed within a week’s time.

Pool-Centric Vision Posed Technical Challenges

_DSC7399.1.72

Faced with a significant technical challenge, Alfandre Architecture, PC and its construction company, EcoBuilders Inc., teamed up with Bensonwood to fabricate and install the large-span glulam timbers and insulated shell of this spectacular 6,000 SF timbered dream house — all built around a large 2,000 SF indoor pool — for their client, a retired couple in Putnam County, NY.

pool house living areaThe challenges included engineering the long timber spans of the pool room, humidity control and the sensitivity of the rocky build site, to name a few. Here, Bensonwood’s expertise in timber engineering, off-site fabrication of panelized assemblies and rapid on-site installation was instrumental in realizing the ambitious project with minimal disruption to the ecology of the home site.

The house, recessed into the bedrock of its 15-acre site, was designed by architect Rick Alfandre to complement its natural setting, with the pool room both anchoring the design and providing the homeowners with the physical, social and emotional benefits of their daily one-hour swim. To add to the ambiance, the light-drenched, four-bedroom, five-bath home has over 70 triple-glazed windows to draw the surrounding landscape into its interior.

pool in upstate ny dream houseGC and local construction company, EcoBuilders Inc. (owned and operated by Rick Alfandre) completed the foundation and walkout walls, first floor system, infill, window installation, mechanical systems, and finishes.

From this project, Bensonwood went on to contribute the timberframe and roof panels for Alfandre Architecture’s offices across the Hudson River in New Paltz, NY, for which Alfandre is seeking LEED Gold certification.

Bensonwood Featured in “The New Net Zero” by William Maclay

the new net zeroThe New Net Zero: Leading-Edge Design and Construction of Homes and Buildings for a Renewable Energy Future

Bensonwood is featured prominently in a new book on Net Zero building by renowned architect William Maclay. We collaborated with Maclay Architects as a member of the team which designed and built the award-winning net-zero Bosarge Family Education Center at the Coastal Maine Botanical Gardens. The LEED Platinum-certified center was Maine’s first net-zero institutional building.

The new threshold for green building is not just low energy, it is net-zero energy, and in The New Net Zero, sustainable architect William Maclay charts the path for designers and builders interested in exploring green design’s new frontier—net-zero energy structures generating as much energy as they use while remaining carbon neutral.

Since traditional American buildings account for roughly 40 percent of our total fossil energy use, the significance of net-zero building is growing increasingly important—among designers interested in addressing climate change as well as homeowners concerned about energy efficiency and long-term savings.

Maclay, an award-winning net-zero designer whose buildings have achieved high-performance goals at affordable costs, makes the case for a net-zero future; explains net-zero building metrics, integrated design practices, and renewable energy options; and shares his lessons learned on net-zero teambuilding with like-minded companies such as Bensonwood.

The comprehensive overview is accompanied by several case studies, which include institutional buildings such as the Bosarge Family Education Center, commercial projects, and residences.  Both new-building and renovation projects are covered in detail. Unity Homes is profiled in the book, as is our multi-layered Open-Built® system.

The New Net Zero is geared toward professionals studying net-zero design, but is also suitable for laypersons seeking inspiration and strategies for beautiful and renewably powered net-zero options.

Our Building Systems Flawless in 3rd Party Inspection

2014.01.16_Panel shop (25) - Copy Four times a year, TR Arnold, a respected third-party “in-plant inspection agency,” or IPIA, is authorized by us to conduct unannounced inspections at our Blackjack Crossing production facilities. In voluntarily submitting to TR Arnold’s findings, our intention is to ensure that construction standards (state & local code, as well as our own stringent standards) are consistently adhered to.TR Arnold

Essentially, TRA inspectors go through each of our work stations inspecting up to 120 certification elements. As part of this quality control process, TRA inspectors are authorized to, “…reject non-compliant units, to withhold labels and to inspect all finished units produced and labeled prior to a unit found deficient and subsequent to the last unit inspected at the station where the deficiency occurred.”

One such audit has just concluded, and we’re pleased to report that of the many assemblies inspected, no non-conformance issues were discovered and we were found to be in complete compliance.

According to Building Systems specialist, Scott Bosworth, “This is really a big deal because of our building techniques compared to other, very different kinds of prefab home builders. For example, with “Double-Wide” manufactured homes that travel down the highway in halves, there are only two certificates required: one for the left side of the house, and one for the right side. With our many panelized assemblies (that are later raised at the build site), there are 120 or more certification elements that can be inspected prior their leaving our production facilities.”2014.02.07_Panel shop (8)

As Scott elaborates, “And because of the kind of closed-panel, or closed-cavity assemblies we fabricate offsite, building inspectors at the home site appreciate seeing certifications created by independent, in-plant inspectors who have seen the panels come together at the point of manufacture. Therefore, getting a full compliance report from a third-party administrator is huge,” adding, “A perfect score from a company like TR Arnold not only helps affirm our own quality control efforts, but in some cases, having the certificate can also help reassure a local on-site building inspector regarding enclosed areas he or she cannot readily see into.”
2014.02.07_Panel shop (2) - Copy
According to Bensonwood/Unity Homes production head, Kevin Bittenbender, who is in charge of compliance control and was instrumental in setting up independent plant oversight, “We’ve been building to the highest quality standards for years. It’s just what we do. It wasn’t much of a change in our process, or product, to meet TR Arnold’s standards. We simply had to clearly explain and document our product, and how we work. Our standards are higher than what is needed for code, and receiving positive results from their inspections is a nice confirmation that we are successfully building to the highest standards in the industry.”

Customized Unity Xyla 212 Sits Softly on the Land

xyla 212

Artist’s rendering of our standard Unity Homes Xyla 212.

Dan Farrell and Melora Kennedy have long been interested in nature conservation. So when they wanted to build a healthy, comfortable, energy-efficient home — close enough to town that he could walk or bicycle to work—a friend, builder and energy consultant, Mark Snyder, suggested they call Unity Homes. Dan works for the Vermont Chapter of the Nature Conservancy as their Conservation Information Manager/GIS Analyst. Melora teaches preschool and kindergarten. The “GIS” in Dan’s title stands for Geographic Information Systems: a science which lets us visualize, question, analyze, interpret and understand data to reveal relationships, patterns, and trends. In the conservation context, GIS would come in handy in evaluating the impact his new home would have on his sloped, 8.9 acre parcel of land, with its old field species and natural plantings — some edible — as well as diverse wildlife crossings.Screenshot 2014-06-23 10.06.14 Unity’s low-waste off-site fabrication and rapid on-site assembly — coupled with its natural materials, extraordinary energy efficiency, and energy-sipping mechanical systems — will all help to reduce the carbon footprint on the sensitive landscape. Their Xyla 212, customized for a walkout, is heated and cooled with an air source heat pump and an optional ERV (Energy Recovery Ventilator) to condition air with minimal energy loss. Both HRV (Heat Recovery Ventilator) and ERV systems are vastly more energy efficient than plain ventilation systems or exhaust-only systems with no heat or energy recovery. Despite its higher up-front cost, Dan chose an ERV system for its edge in operating efficiencies, air filtration, degree of comfort (through greater humidification/dehumidification control) and environmental impact.

air pohoda ashp

The Air Pohoda ERV used in the Farrell home in a special housing devised by our Building Systems team.

Unity’s standard HRV system is designed to recover approx 80% of the heat in the air that is being exhausted from the house, while the ERV (Energy Recovery Ventilation system) is expected to recover over 90%. Given the ERV’s added efficiency, there would be a relatively short payback period on its premium cost over the standard HRV system. In comparing the ventilation systems, the ERV units are expected to save about 1315 kWh per year over the HRV system. At $0.15/ kWh, that comes to almost $200 per year at the current electric rate, with those savings continuing to rise as electricity rates increase. The Return On Investment calculator projects an 11-year payback on the $3,000 additional investment over the cost of a comparable HRV system.  (Source: EPA Greenhouse Gas Equivalencies Calculator.) IMGP7792But for Dan and Melora, it wasn’t just a matter of dollars and cents. Framing it more in conservation terms, the 1,315 kWh per year saved by their ERV over the HRV, is equivalent to 102 gallons of gas, 97 lbs. of coal or 21 barrels of oil. Saving that energy would be the carbon equivalent of 23 tree seedlings grown for 10 years or 0.75 Acres of forest grown in one year. The 2-bedroom, 1-bath Unity Xyla, with its super-efficient 1,028 SF first floor space plan and optional 939 SF walkout level, celebrates the lagom values at the heart of all Unity Homes. Roughly translated, lagom is a Swedish word meaning “not too much, not too little —  appropriately balanced.” The home is neither too big nor too small, but just right perched lightly on its steeply sloped site and in-balance with its surroundings. work in progress Xyla 212Entry is from the up-slope side (and future patio) directly into the living area, which is open to the eat-in kitchen and second bedroom. Down a short hallway and adjacent to bedroom two is the master bedroom and common bath. Dan and Melora plan to leave the ground floor, with its separate down-slope entry, unfinished for the time being, but it will eventually have a rec room and second bath. With the home fabricated off-site and assembled on-site over late spring/early summer, the Farrells expect to be in their home by mid August.

New from Bensonwood: Architecturally Correct Fire Doors

bensonwood fire doorWhen it comes to our automobiles, we’ve come to expect that safety not take a back seat to design. The form must incorporate that function. However in residential architecture, where architectural details and natural materials can play such a fundamental role in creating a sense of home, the limited availability of beautifully-crafted, architecturally-accurate wood doors that are also fire-safe can too often force a Hobson’s choice of “take it or leave it” and a door that does not match the rest of the home’s interior.

Now, beauty and safety are no longer mutually exclusive. Bensonwood offers architecturally correct stile and rail wood fire doors and jambs, all crafted to the same standards as our homes. Whether for your new Bensonwood or Unity home, or à la carte as stand-alone assemblies, these fire doors are designed and built to meet the highest safety, durability and aesthetic standards in designs that complement the architecture—all while achieving tested and independently certified safety ratings.fire door pdf

Available in a wide variety of styles and customizable designs, these fire doors include: thick, real wood veneers in a broad range of material and pre-finishing options, traditional mortise and tenon joinery and ball bearing hinges. The doors also include Fyrewerks’ cores made by combining intumescent compounds (a substance that swells as a result of heat exposure) with water-based ingredients and binding agents. When exposed to extreme heat generated from fire, the intumescent properties of the core expand to create an inorganic mass at the door’s core. The result is a passive fire-retardant cavity that insulates the door for up to 90 minutes. All of our fire doors and jambs are certified by Intertek for 20-minute, 45-minute, 60-minute or 90-minute fire ratings.

Sunday River Ski Retreat: The Best of All Worlds

Tedford ElevationSome ski homes high on the mountain have beautiful views down the valley. Others near the base lodge typically have great views up the slopes. This timberframe home at The Glades at Ridge Run, a new slopeside residential neighborhood at Sunday River Resort in Newry, Maine, captures both.

Situated in the western mountains of Maine just three hours from Boston, Sunday River Resort has long been one of New England’s most popular four-season playgrounds, but what is so special about the property that owners Meredith and Jamie found here is that it sits uniquely midway up the mountain with expansive views above and below.

Though Meredith and Jamie had just completed an extensive renovation on another home and weren’t anxious to begin a new construction, this was the first time a ski-on, ski-off home opportunity was available at Sunday River, so the couple knew they had to jump on it. They were also motivated to replace an old beloved, but small, ski lodge they had outgrown. Sensitive to the feeling of transplanting their relatives away from a getaway that had been in the family for years, they wanted an open concept floor plan with the feel of a true home. They also wanted to maximize family interaction, and minimize the size of the house to facilitate that function—as well as for aesthetic and environmental impact motives.

sunday river family ski lodge renderingPast renovations had taught Meredith and Jamie to be flexible but decisive, which helped in this first new house project. They also knew from experience that “design by committee” was something to be avoided, rather it was better to create a team dynamic between client and architect that respected roles and responsibilities, but also valued input from all parties. The mutual trust that developed allowed changes to be made fluidly and without conflict.

The Bensonwood design team of Randall Walter, Curtis Fanti and Dave Levasseur, all avid skiers in their own right, were excited to create this special place from a perspective of years spent skiing and snowboarding. Their personal insights proved invaluable in informing practical aspects of the design.

The architectural review process at the resort and the corresponding design standards requires development that complements the surrounding natural setting; minimizing the impact on the landscape while allowing for individual freedom of design to suit the needs of each homeowner. A common theme, described as a Northeast Cottage with Adirondack and Shingle Style influences, dictates the use of building materials, colors, landscaping and building style at the resort. The style is best illustrated in Summer Cottages in the White Mountains by Bryant F. Tolles, Jr. (2000), in which the use of native materials blended with natural colors provides an effective link to both the local environment and the great cottage architecture of the early 20th century.

Sunday river ski lodgeWorking closely with the clients, the resort, the civil engineering firm Main-Land Development Consultants, Inc., and the town zoning board, Randall was able to design the energy-efficient home into a challenging site with steep terrain and protected wetlands. He was able to navigate the regulations and arrive at the design—a traditional Adirondack timber lodge style with a modern twist on the gables to accommodate the views—in a way that pleased all the parties involved. In the end, the review board process was easy and the owners got a home that fit their needs and respectfully fit the mountain landscape.

Another welcome test for Bensonwood is the truncated construction timeline. With designs finalized this past spring, the owners wanted to ski from the home this coming winter. Anxious to prove that even a custom 3,900 SF mountain home on an undeveloped site could go up in record time with our Open-Built® systems and offsite fabrication, the Bensonwood team embraced the challenge. Rapid onsite assembly will also help cut build times in half over conventional construction, effectively giving the homeowners an entire extra season to enjoy the resort.

ski deckLike many of Bensonwood’s mountain and shore homes, the house features gable roof lines, with one important distinction: these gables, dormers and bump outs will have asymmetric rooflines that permit both mountain and valley vistas as well as views of arriving and departing skiers. These roof angles, along with the heavy, rough sawn, red cedar clapboards, work to give the exterior its distinctive look: at the same time both traditional and contemporary, while the property’s southern exposure allows for plenty of natural daylighting and passive solar gain.

On the inside every detail of the sanctuary, which will accommodate three generations of family, has been strategically planned. The owners wanted to maximize the use of space, and that included the kids’ space on the ground level, with the fun feel of a ski resort locker area. The ground floor has a rustic lumberjack-inspired kids zone, with a mud room off the garage, an open play area, a game room, a guest bedroom, a bunkroom with three beds, and facing his and hers bathrooms.

The first floor has a large open space plan with cathedral ceiling and a gathering area across from the kitchen/pantry and adjacent to the dining area. The dining room will have a long, farmhouse-style table with benches accommodating 10 or more. The second floor plan has three bedroom suites, each with their own bath, and a balcony open to the gathering area below.

sunday river ski lodge renderingPerhaps the most unique feature of the project, however, is a very innovative ski-on, ski-off deck. The custom deck required Randall to create a multi-functional outdoor living space with views up and down the mountain in a style that also satisfied design review board restrictions. His solution was adjust the roof pitch and angles so skiers on the deck will still be able to enjoy the views, as he had done on the main house.

Mindful of the homeowners’ sensitivities to limiting the home’s size, he placed the deck atop the garage so skiers will have easy to the home’s bathrooms and kitchen on the main floor when they ski home at lunchtime. Unique features include a hot tub—not tucked away in a secluded spot as is often seen—but in the open air on the sheltered ski deck so all guests have ready access. There are also ski and snowboard racks, overhead heating elements, a fireplace and a hot tub on the deck.

FLOORPLANOne of the most creative elements of the home is one the clients devised. Rather than the traditional guest book for visitors to sign, the couple will immortalize them with a round timber into which they can carve their names and the dates they stay, creating a family legacy crafted in wood that will last for generations—just like the home.

Architect Randall Walter predicts that, like many vacation homes Bensonwood has crafted over the past 40 years, this house will be used much more than originally intended, because families often discover they enjoy spending time in them so much more than in their primary residence.

 

 

 

1st evoDOMUS – Bensonwood Project Underway

evodomus rendering

Architect’s Rendering by Alexander Kolbe

When husband and wife architects Alexander and Michelle Kolbe, co-founders of evoDOMUS, a Cleveland-based firm, wanted to design and build high-quality, sustainable homes in the U.S., they went looking for a manufacturing partner who could match the quality of homes they built in Alexander’s native country of Germany.

They sought a montage homebuilding company of the caliber of the venerable Huf Haus and Baufritz, Germany’s leading off-site building companies, which helped establish off-site panelized building as the primary construction methodology throughout Europe. Both companies are more than a century old and, like Bensonwood Unity Homes, combine timber framing influences with advanced design and high-performance building.

However, the Kolbes wanted a more personal connection to the client through the entire process—the level of attention a smaller company could provide—to reduce the stress homeowners often associate with a custom house project, such as designers not tuned-in to their clients’ needs, unreliable contractors, as well as schedule and budget overruns. After thoroughly researching high-quality panelized builders, fabricators and timberframers, the names Tedd Benson and Bensonwood kept popping up. So Alexander got on the phone and, much to his astonishment, Tedd picked up.

Upon hearing of the Kolbes’ high standards and montage building interest, Tedd replied, “That’s exactly what we’re doing!” A meeting with Tedd and project manager Hans Porschitz followed and it was soon apparent that the synergies and shared values of the two companies were aligned. A relationship was established: Bensonwood would fabricate the evoDOMUS home shells.

Now, the first joint project between evoDOMUS and Bensonwood is underway in Fairfield County Connecticut: a 5,000+ SF 4-bedroom Bauhaus-inspired modernist home in the “Cloud” Series of evoDOMUS homes. Strikingly original and family-friendly, Cloud is also inspired by current Mexican and Spanish interpretations of modern residential architecture. Customized to their clients’ needs, the home’s clean lines, contemporary materials and use of advanced building science are all characteristic of evoDOMUS home designs.

evodomus elevation

East & West Elevations

Designing the home for its two-acre site had its challenges; its wooded setting with wetlands, an awkward slope and rock ledges all needed careful  consideration. In addition, the home had to incorporate passive as well as active solar design, requiring precise siting along with design elements such as a south-facing second floor loggia to shade the first floor in summer months.

The Kolbes’ strong focus on sustainability prompted the use of triple-glazed Loewen windows and a Zender Energy Recovery Ventilator, which recovers up to 90% of the energy of the extract air to warm the incoming fresh air, saving on heating costs. The air distribution system then channels the optimally tempered fresh air to individual rooms as needed. The exterior is clad in Resysta siding made of rice husks, common salt and mineral oil, which makes it both environmentally friendly as well as extremely weather resistant against sun, rain, snow or salt water. Resysta siding also requires minimal care and offers the look and feel of wood and can be painted.

The home has 4,100 SF of living space with 2 stories above grade and a 900 SF finished basement and 924 SF garage. Off the garage are a mud room, a half bath and a yoga fitness room. The first floor has an open great room with living and dining areas adjoining another open space with a kitchen and family room. Rounding out the first floor is a bedroom/study with adjacent bath. The second floor plan includes the master bedroom, three additional bedrooms (each open to a long balcony), a family bath, a study and a laundry room.

First Floor Plan

EvoDOMUS uses low or no VOC paints and finishes in their homes and only formaldehyde-free materials. Material selections consist primarily of products with high-recycle content, as well as FSC certified woods and bamboo.

Alexander and Michelle Kolbe wanted to offer their customers not only the highest quality, sustainable homes available, but an excellent experience as well. By partnering with Bensonwood, evoDOMUS could put its resources into delivering superior design, customer service and care, rather than making investment in fabrication facilities, with financial partners and the loss of control and client interaction that would imply.

By maintaining that control, evoDOMUS is able to fulfill its mission of making homes as beautifully designed and high quality as German cars—with a customer experience to match.

Unity Homes: Indoor Air Quality and Comfort

unity homes kitchenYou can live 21 days without food, 7 days without water, but only a few minutes without air. Every day we take 21,600 breaths; that’s nearly 8 million breaths of air a year. By weight, we take in more air than food: 4,500 times our own weight in an average lifetime.*

On average, we spend 90% of our lives indoors, and approximately 2/3 of that time is spent at home. Today’s health conscious consumers will pay a premium for healthy, natural foods, but often give less thought to indoor air quality or overall healthiness of their homes. A recent McGraw Hill Construction report, “The Drive Toward Healthier Buildings,” finds that most homeowners turn to family, friends or coworkers for advice on home products and practices, with few requesting advice from the builders, remodelers and architects who know most about how these decisions might affect occupant health.

However, homebuyers are increasingly concerned about the Indoor Air Quality (IAQ) of their homes. Pollutants like mold, radon, carbon monoxide and toxic chemicals are receiving greater attention than ever as poor IAQ is linked to a multitude of health issues. Some pollutants cause health problems such as sore eyes, burning in the nose and throat, headaches or fatigue. Other pollutants cause or worsen allergies, respiratory illnesses, heart disease, cancer, and other severe long-term health issues. At high concentrations, pollutants such as carbon monoxide, can be fatal.

Given how important air is to life, let’s examine perhaps the most important attribute of Unity Homes, and properly built high-performance homes in general, which is how they can help you breathe easier and live healthier.

air pohoda ERV

Air Pohoda’s Ultima 240E i-ERV uses an Enthalpy heat exchange core

To start, only low VOC (Volatile Organic Compounds) materials and finishes are used in the construction of Unity highly-insulated, tightly-sealed, energy-efficient homes, resulting in exceptional levels of indoor air quality. Because of their extraordinary air-tightness, the indoor air is continuously replenished with fresh and conditioned air, reducing the energy losses that typically come from whole house ventilation. This is accomplished by the use of a standard Heat Recovery Ventilator (HRV) or optional Energy Recovery Ventilator (ERV) with adjustable humidification and dehumidification controls. 

Regardless of which ventilation system is chosen, Unity homes come standard with air-source heat pumps (for heating and cooling). When properly installed, an air-source heat pump can deliver one-and-a-half to three times more heat energy to a home than the electrical energy it consumes, according to the U.S. Department of Energy.  This technology loses less humidity in the winter than with forced hot air/furnace systems that scorch the air at high temperature—driving off its moisture—making an outboard humidifier consume more energy to replenish it. Finally through filtration, allergens and other pollutants can be removed, making indoor air considerably healthier than outside air.

Why build tight houses that require sophisticated ventilation systems, you ask? There are many myths held by the public (and by many builders as well) surrounding the false notion that houses need to breathe. This bogus theory holds that houses can be too tight and that air leakage or “natural ventilation” dries everything out and keeps the air quality healthy. But as Green Building Advisor.com points out, “…air leaks mean you’ve lost control of air movement…air and moisture can be forced into wall and ceiling cavities where water vapor condenses and fosters the growth of mold.”

Additionally, according to Green Building Advisor.com,

“Warm air exiting the top of the house can draw in cold air to replace it, wasting heat and energy. In many ways, uncontrolled air movement wastes energy and increases the risk of long-term damage to building components. Effective air and moisture barriers reduce those problems, but they come with a few caveats: Tight houses need mechanical ventilation to ensure a supply of fresh air to keep people healthy.”

a Unity Homes Xyla 212

And while we’re on the subject, what exactly is “fresh air?” Most would assume outside air is fresh air, but whether you live in the city or the country, outdoor air carries pollutants in the form of gasses, droplets, and particles. This includes pollution from cars, trucks, airplanes, industry, tractors plowing fields, wood and crop fires, ground level ozone, and allergens like pollen. Indoor air, too, can contain a host of pollutants from combustion sources like stoves and furnaces, to high VOC building materials and furnishings, to household cleaning products and radon, to name a few. All of these pollution sources can cause health problems if not mitigated through green building practices and sophisticated air handling technology.

Unity Homes, and other quality high-performance homes, help you breathe easier and live healthier by using only green materials and finishes, by sealing out unwanted moisture, dirt, dust, insects and allergens that can lead to health problems and costly repairs, and by conditioning and filtering incoming air. At the same time, Unity’s well insulated and tight building envelope reduces overall heating and cooling costs, and adds comfort by eliminating drafts and temperature variations.

Moreover, while a Unity Home conditions your indoor air, its low-waste, precision offsite fabrication and super-efficient energy performance thereafter works to lower its impact on the outside air—which we all share—as well.

Southern Comfort: A Unity Zūm Rises in Asheville, NC

front 2Zum_Mimken_DD_Page_1Situated 2,000 ft. above sea level in the Appalachian mountains, Asheville, North Carolina has a full range of temperatures with average January lows of 28 degrees F and average July highs of 85 degrees F, making it a prime location for Unity Homes’ energy-stingy houses. In a nutshell, Zūm’s low-load building envelope offers year-round comfort with minimal energy input, making F3 (fossil fuel free) living easily achievable. And when combined with energy rebates and incentives, the Zūm the home was even more affordable.

In addition to financial health, Zūm promotes personal health as well with its green, low-VOC materials throughout, exceptional indoor air quality, minuscule room-to-room and floor-to-ceiling temperature variants, abundance of natural light, and sound dampening shell that keeps outside noises outside.

2013.11.27_Zum_Mimken_DD_Page_2The client for Unity’s first Zūm, Nick Mimken, is a repeat client, having built his first house with Bensonwood back in 2001: an island house on Nantucket. According to Nick: “I had had a very good experience building the timber frame Nantucket house: it proved to be everything you said it would be…and more,” adding that “the Bensonwood architect, Bill Holtz, and the crew had been top notch and worked amazingly well with the local builder.”

On his latest homebuilding project with Unity Homes, Nick continues:

 Fast forward a dozen or so years and this time around I was thinking about downsizing and wanted something smaller and energy efficient when I learned about Bensonwood’s new Unity Homes. Being interested in zero energy design, I visited your headquarters, met with architect Randall Walter and sales person John Dunbar, and as before, I was impressed with the way you use the latest technology. They walked me through the computer modeling and site lines, etc. and I was sold on the process.

IMG_7150Unity Homes provided a “Tempo Offering;” a package including the home’s shell, millwork and mechanicals—ideal for do-it-yourselfers wanting to complete their prefab home in phases, or in this instance, for a client looking to build on a distant site outside our home region of New England—hiring a local builder to finish the home.

MIMKEN ZUMThe builder, Jody Guokas of JAG Construction, is finishing out the home with contemporary cement panels similar to those used on our Unity House college president’s residence in Maine, and on the Catherine Houghton Arts Center in the White Mountains of New Hampshire.

Again, according to the owner/builder:

 “My local green builder, Jody Guokas, wasn’t interested in the project initially, but when he learned that Bensonwood had designed the home and would be installing the shell, he jumped on it. He wanted to learn from Bensonwood’s processes. One member of Jody’s crew had even worked at Bensonwood for a spell, so the fit was perfect.”
