Slideshow: 5 Modern American Farmhouses | Dwell. “A pitched roof doesn’t necessarily mean a home is stuck in the dark ages of the American architectural vernacular. In fact, the following modern farmhouses—which either underwent a transformation or were built with the style in mind—prove that gables and porches can be very modern indeed.” We couldn’t agree more! In fact, Tedd Benson has been saying this for years, but we’re glad the world is catching on….
Steven and Barbara Landau’s Norwich, Vermont, Passive House won The Builders and Remodelers Association of Greater Boston (BRAGB) Prism Gold Award for “Best Energy-Efficient Project.” Bensonwood, who designed the prefabricated insulated panels and constructed the timberframe shell, was honored as part of a highly-skilled green building team that included energy modeling and mechanical consultantsZeroEnergy Design, consulting architect Paul R. Bilgen, general contractor Estes and Gallup, and custom window and door maker, Architectural Openings. The innovative, sustainable home previously won the 2012 Efficiency Vermont “Best of the Best in Residential New Construction” Honor Award.
The 17-inch recycled foam sheet insulation provides R-75 value and a vapor barrier below the slab. All hot water is provided by two rooftop, flat-plate solar collectors with an electric on-demand water heater for backup. One kilowatt heating mats located under floor tiles in the bathrooms supply radiant heating, and air exchange is managed by a Heat Recovery Ventilator whose operation automatically adjusts, depending on temperature, humidity, and occupancy. In the kitchen/living room a sealed combustion chamber wood stove serves both as cooktop and bake oven, as well as a source of supplemental heat. The eco-friendly 2,457 square foot home also earned 41 Home Energy Rating index points, meaning it is 59% more efficient than a standard new home.
BRAGB, a trade association affiliated with the National Association of Home Builders and Home Builders Association of Massachusetts, has represented the building industry since 1944 and is one of the leading trade associations in New England.
Many have asked us why we use dense-packed cellulose insulation in our OBPlusWall® panels, roofs and some ceilings and floors. Here are some of the cellulose advantages in our “Montage Building” system:
- Our cellulose insulation is made from recycled newspapers treated with a natural mineral borate to give it a Class A fire rating as well as resistance to mold and pests.
- The dry cellulose is blown into all the framing cavities at a settle-proof density (dense-packed), filling any shape with a continuous thermal insulation layer. The blowing process compresses the cellulose to a density of between 3 and 4 lbs/cu.ft. In addition to preventing any settling of the material, the dense-packed cellulose also cuts down convection that can occur around batt type insulation and in low-density blown fiberglass, particularly in colder temperatures.
- Dense-packed cellulose blocks air movement better than fiberglass batts. While sprayfoam also seals the enclosure against air infiltration well, its rigid consistency when cured may allow it to crack as framing members around the insulation dry and move over time. Cellulose has the flexibility to allow for such movement without resulting gaps.
- Similar to wood fiber, paper cellulose fiber manages moisture well, taking in and releasing the moisture effectively. As a result, indoor relative humidity is much more even due to the hygroscopic buffering capabilities of the cellulose insulation. This is in contrast to the hydrophobic characteristics of fiberglass and foam insulations, which lack this capability and can cause a home’s interior to experience significant swings in humidity when weather changes. So, with its tremendous insulating and moisture management characteristics, cellulose helps to buffer temperature and humidity extremes.
- While foam insulation has a slightly higher R-Value per inch, cellulose takes less energy to manufacture than any other insulation material. This embodied energy includes the total energy required to transport the raw materials, then manufacture and distribute the finished product. Fiberglass has up to 10 times more embodied energy than cellulose and foam products have as much as 64 times more.
- Cellulose insulation is one of the greenest building products, having the highest level of recycled content in the insulation industry—as much as 85%. Fiberglass has a maximum of 40% recycled content and foam products little or none.
- Cellulose sequesters carbon in a building’s components instead of releasing it into the environment. Cellulose insulation is made from recycled paper that might otherwise end up in landfills, releasing methane as it decomposes, or be burned, releasing CO2. This sequestration results in a positive carbon balance which helps the efforts to lower the material’s impact on climate change.
- Cellulose insulation is produced regionally, employing local recycling programs and independent recyclers.
- While all insulation provides sound reduction, cellulose has approximately three times the density of fiberglass as well as fibrous consistency, delivering enhanced sound dampening.
A year ago when Carol and Ed Reardon wanted to build a healthy, energy-efficient, year-round residence on a lake, they knew whom to call.Bensonwood had recently launched its sister company, Unity Homes, which offers healthy, high-performance, more affordable homes. Here was their chance to own a high-quality Bensonwood home on a budget they could afford. Best of all, they discovered they would be living in the home in only five months’ time.
