NH Architect Jeremy Bonin's Interviewed by Timber Home Magazine

The September 2008 Special Green Building Issue features an interview with NH Architect Jeremy Bonin on energy efficient home design, sustainability, and timber framing.

Writer Peter Lobred asks Jeremy Bonin, a LEED accredited architect and the author of the timber frame book, TIMBER FRAMES: Designing Your Custom Home, pointed questions about building a timber frame home and incorporating sustainable design. After explaining some of the catch phrases in the green building industry, Jeremy answers questions such as “What are some basic considerations – or the most crucial elements – that consumers / architects can incorporate into their plans for sustainable design?” and “Does there seem to be a natural fit between timber frame homes and green considerations?”

Asked about the cost versus benefits of energy efficient home design and sustainable options, Jeremy reminds homeowners that the simplest solutions are not only the most cost effective and usually provide the largest return on investment. For example, designing the home for passive solar heating and daylighting adds no cost to the home and offers huge savings; using an energy-efficient insulation system such as Structural Insulated Panels (SIPs) to keep heat in and cold air out and only designing as much house as you need means lower energy bills for years to come.

If you’re building a green home, whether it’s timber frame, post and beam, structural insulated panels, or another energy efficient building system, energy efficient home design starts with the site selection and site design. Jeremy suggests consulting with an architect in the earliest possible stage, even prior to purchasing your land, and discussing your ideas and green materials you want to incorporate.

Choosing Green Building Materials

There are certainly an abundance of green building materials on the market today. How do you determine which one is better than the other? One way is by considering its life cycle: where its raw materials come from, how it is manufactured and what happens during the manufacturing process, and where the product ends up. These are some things to consider when comparing green products:

Do the raw materials come from:
  • The earth;
  • A forest;
  • Chemicals mixed together
How are they harvested, and do they create waste or harmful material?

After being manufactured, how far does the product travel to get to distribution centers and you, the consumer?

Does the material require sealants, urethane finishes, or adhesives for installation (these usually involve using chemicals)?

Is the material durable and can it be easily repaired if necessary?

Fifty years from now, will the material be:

  • In the landfill in exactly the same form it was manufactured in;
  • Recycled into another product or material;
  • Biodegraded, having been broken down by microorganisms and bacteria
In the future, green building materials will come with labels listing the raw materials, contribution toward global warming, impact on carbon footprint, ozone depletion, health concerns, habitat impact, and other influences on our global environment. In the meantime, you can rely on your green architect to help you choose the building materials that are right for your project, the environment, and your immediate [and future] budget.

Energy Star Home

ENERGY STAR® is a joint program of the U.S. Environmental Protection Agency and the U.S. Department of Energy that provides information, training, and certification of products and practices to help homeowners save money and protect the environment.

If you are building a home, consider having it designed to meet ENERGY STAR standards, which will save you 20% - 30% in energy costs, create a healthy indoor environment for your family, reduce air pollutants, dust, and drafts, and, as an added bonus, increase the value of your home.

One of our current projects is a
timber home designed to be built to earn ENERGY STAR certification. The barn style home design fits in nicely with the architectural style of the surrounding area of Old Lyme, Connecticut.

The home will include ENERGY STAR approved insulation (SIP panels), duct system, mechanical ventilation system, windows, heating and cooling units, lighting, and appliances.

At 2500 square feet, this energy efficient home has views to the south and west.

The first floor features a timber frame cathedral great room and a Tulikivi stove. The kitchen has views overlooking the property and is open to the dining, with easy access to the laundry room, and large master bedroom suite.

The second floor has two guest bedrooms, a full bath, and a spacious loft overlooking the great room. In the next design stage, we will complete room dimensions add interior and exterior details.

Check out this and our other current
green homes on our website!

Comprehensive Shoreland Protection Act

It's that time of year! School is almost out, summer is upon us, and soon New Hampshire's lakes, rivers, and ponds will be buzzing with activity. Many folks from Massachusetts, Connecticut, and Rhode Island come to New Hampshire every year to enjoy our beautiful surroundings - and some plan to relocate or build a vacation home here.

The Comprehensive Shoreland Protection Act was established in 1994 to help protect New Hampshire lakes and ponds from erosion and sedimentation as a result of construction and land use activities within 250’ of the shoreline. The Shoreland Protection Act affects all homeowners planning to build on or subdivide New Hampshire lakefront property. Amendments to the Act went into effect July 1, 2008.

Even lawmakers agree many “gray areas” still exist in the Act and its amendments, including restrictions on building size, accessory structures and the amount of clearing that can be done, boathouse construction, and conflicting state vs. town setback requirements.

If you own land on the shores of a lake, pond, or river and are thinking about building a lakefront home which will have to comply with the Comprehensive Shoreland Protection Act requirements and restrictions, give us a call or send an email. We can help you design and build a comfortable, energy efficient home within the guidelines and restrictions of the Act - and make building a lakefront home an enjoyable process!

Energy Efficient Windows

What to Look for in Energy Efficient Windows:

In 2005 the National Fenestration Rating Council (NFRC) developed a label to provide consumers with energy performance data on windows, doors, and skylights. This label helps you compare one product to another, listing the manufacturer, a product description, a source for additional information, and ratings on the following energy performance characteristics (windows and doors are rated as whole systems, glazing and frame).

U-Factor: A window’s U-Factor measures how well a unit prevents heat from escaping (the inverse of its R-value). U-Factor ratings are usually between 0.25 and 1.25. The lower the U-value, the greater its ability to resist heat transfer and better insulate the home.

Solar Heat Gain Coefficient (SHGC): The Solar Heat Gain Coefficient rating indicates how well a window, door, or skylight blocks solar heat by measuring solar radiation released into the home. The lower the coefficient value, the less solar heat is transmitted into the home. Numbers generally range from 0 and 1, typically ranging from 0.25 to 0.8.

Visible Transmittance (VT): Visible Transmittance measures how much visible light is transmitted through the glazing. The higher the number, the more light is transmitted.

Air Leakage (AL): Air leakage ratings test the equivalent cubic feet of air that passes through one square foot of window area. Heat can be lost and gained through seals in the window frame and assembly. The lower the air leakage number, the less air passes through the unit. Most industry standards require an AL value to be 0.3 cfm/ft2.

Condensation Resistance (CR): The condensation resistance rating measures the units ability to resist condensation forming on the inside of the product. Ratings are expressed in numbers from 0 to 100. The higher the rating, the better the product resists condensation.

Consult with your architect on the best windows for your green home project that will meet your energy efficiency needs, site specific requirements, code requirements and budget. Lawrence Berkley National Laboratories offers a free software program, Resfen (PC-compatible only) which lets you calculate how windows with different glazing systems and frame materials affect your energy bills.

Window Designs

Windows are an important design, energy, and cost consideration for a green home – whether you’re building a timber frame, post and beam, or sustainable home using recycled and/or energy efficient material. We expect windows to enhance the beauty of our home and perform many functions: admit natural light, block summer solar heat gain, resist condensation and capture solar heat in winter (and prevent its loss).

The most common kinds of windows available are wood, clad-wood, vinyl, and aluminum.

Wood windows are traditional (wood on the interior as well as the exterior, however, wood swells and shrinks, so the window must be carefully and properly constructed and installed per the manufacturer’s guidelines. Warping and rotting will occur over time unless the window is protected. You can order wood windows either finished or unfinished. Solid ‘un-clad’ wood windows are not a typical selection.

Clad-wood windows have a wooden frame typically with extruded aluminum or vinyl cladding on the outside. The cladding completely covers the frame – meaning it won’t need maintenance for years. Most claddings have 15 year warranties on the finish and some manufacturers offer as many as 50 color selections to choose from. Clad windows are one of the most common window types.

Vinyl windows, made from rigid polyvinyl chloride (PVC), they have hollow spaces inside to help them resist heat loss and condensation. While they cannot be painted, the color permeates the material so scratches do not show. Some windows have a tendency to warp when exposed to extreme heat or cold, which makes them harder to operate and allows air leakage. Vinyl windows are also a common choice and tend to be less expensive than clad windows.

Aluminum windows are thinner, lighter, and easier to handle than wood. A thermal break of extruded vinyl insulates the window, and sometimes includes foam, reducing heat loss and condensation in the window. Aluminum windows are typically more common in commercial construction than residential.

In typical residential or light commercial projects, aluminum clad wood windows are the preferred choice. The wood offers good thermal performance characteristics while the aluminum cladding protects the window from the elements. The finishes on the aluminum are available in a wide choice of colors and the interior wood finish may be left natural, stained or painted. Aluminum clad windows are also available in the typical configurations of awnings, sliders, double & single hung and casements as well, and most manufacturers offer sliding and hinged doors to match and compliment their window selections.
