A warm Central Oregon welcome to the 12th Annual Green and Solar Home Tour!
The High Desert Branch: Your Local Connection to Green Cascadia Green Building Council Mission
To lead the transformation toward a built environment that is socially just, culturally rich and ecologically restorative.
HIGH DESERT BRANCH Mission
Realizing tomorrow’s living future, through today’s sustainable choices. We generate opportunities to consider our choices and encourage informed action by providing events and activities that inspire, educate, and demonstrate options for green built environments and sustainable lifestyles in our high desert community. We are excited about joining with others to keep the spirit of sustainability alive and growing in our area for the future health of our economy, environment and community. The High Desert Branch of the Cascadia Green Building Council is proud to present the Green + Solar Home Tour. We’ve reviewed applications, asked local experts, and generally snooped around to find the very best green homes in Central Oregon. The High Desert Branch brings this Tour to you through the tireless effort of volunteers. The Branch is your local connection to a much larger network of Branches that span the Cascadia Green Building Council region (Oregon, Washington, Alaska and British Columbia). Cascadia is a Chapter of both the US and the Canadian Green Building Councils, connecting to an even larger network. Throughout the region, Cascadia works as a leading advocate for progressive green building laws, regulations and incentives. Additionally, Cascadia provides research to find answers to the technical, scientific and economic unknowns at the leading edge of green building. Cascadia is a program of the International Living Future Institute which works to bring substantial transformative change around the world. Enjoy this Tour and consider ways that you can transform your world, one choice at a time. You can support the Tour and the High Desert Branch by joining Cascadia or sponsoring next year’s tour!

We are very excited about the homes, features and technologies associated with the Tour, and invite you to join us. Each Tour is made possible by a dedicated group of volunteers and organizations who believe Central Oregon is the best place on earth to live, and embrace sustainability in all aspects. Centered on this effort is the Cascadia High Desert Branch of the Green Building Council; where our goal is to bring inspiration, leadership and education about sustainable building to our region. We encourage you to help continue to make Central Oregon an even better place by volunteering for next years’ event, or for any event that helps strengthen our spectacular region. If interested, please add your name to a volunteer sign-up sheet at the kickoff or at any home along the tour. The Kick-Off and Tour is brought to you FREE by the generosity of many local businesses and organizations who donate money or in kind contributions. A BIG Thank You goes out to our continuing Title sponsor Sunlight Solar and Platinum Sponsor Energy Trust of Oregon! Other major contributors include the Garner Group, Home Heating and Cooling, Ecodog and Resource Conservation Technologies. Please review this guide and our website for a listing of our many other organizations who donated so graciously but are too numerous to mention here. Many of these sponsors will have booths set-up during the kickoff event so please take the time to visit them. The theme for the Tour is ‘Behavior’ and we are fortunate to have two pioneers in that field as speakers at the kickoff event. Ron Pitt, the CEO from Ecodog, will be giving the keynote address about his choice to start a company to empower people to make intelligent energy efficient choices with the proper knowledge; and Tom Elliott will be speaking about the choices he is making to build C.O.’s first Living Building, and one of the Tours’ featured homes, “Desert Rain”. We are fortunate to have them, as they are experienced, knowledgeable and passionate about the behavioral choices that are required to become a truly sustainable society. The kickoff event is a great place to listen to our engaging speakers and visit with sustainable experts from many different fields, not just the building industry. These experts include solar photovoltaic, solar thermal, certification programs, incentives to help lower the cost of energy efficient upgrades, energy monitoring, Commute Options, and many others. To see all of our vendors please check-out our website www.greenandsolarhometour.com and follow or like us on Facebook. When you are coming to the kickoff event, we encourage you to participate in lowering your carbon footprint by either riding your bike, walking or using public transportation. Several businesses along the Tour route are getting involved in helping to encourage sustainable modes of travel. Details and Tour maps for the Green + Solar Home Tour will be provided at the tour’s kick-off event at COCC and online at the Cascadia Green Building Council’s website, http://cascadiagbc.org/branches/or/high-desert-branch Find transit schedules at: http://www.cascadeseasttransit.com/bendschedule.html See the Tour Map for Bike and Walking Routes, and Tour-goers who participate in alternative methods of travel during the Tour will receive discounts along the ‘bike and walk’ route at Strictly Organic Coffee, Riverside Market, Sage Cafe and Portello.

a well-sealed structure ensures that the house works just as the owner planned (see Green at a Glance for systems and products), and in some cases, even better than was imagined. “Even in the winter, just cooking dinner is almost enough to heat up the main living and kitchen area. We can’t turn on the gas fireplace for more than 30 minutes or we’ll be baked out.” The high level of insulation throughout the house, combined with an orientation that takes advantage of the warming sun, keep this home at a comfortable temperature with minimal use of additional heat sources. The owners hope that this home will serve as a showcase of how to work within a budget to create a home that pleases one’s senses as well as one’s sense of sustainability.

ity bills to near zero, regardless of future utility rate inflation. This home offers long term financial security and environmental responsibility to its future buyers.” And they are not kidding- although much of what makes this level of sustainability possible is invisible to the eye. It is embedded in the four different home sealing measures; the super insulated walls, ceiling, and floors; the passive solar design and low to zero volatile organic compound (VOC) emissions from cabinets, paints, and floors. Even the deceptively simple landscape design hides a greater, greener capacity- with deep gravel drain basins that hold rain water on the site, even in the event of a major storm. What you are aware of is how quiet it is (thanks to the 12 inch walls) and how open and airy it feels (due to the open plan and automatic ventilation system that brings in fresh filtered air). Hopefully, the integrity with which this home is built inspires others towards greater sustainable living.

Make A Difference:
As more Oregonians embrace solar as a clean and smart energy choice for their homes, The Environmental Center is helping make that choice easier and more affordable in Central Oregon. With the launch of Go Solar! Central Oregon, residents in the tri-county area can purchase solar electric and hot water systems for their homes at substantially discounted prices through October 31, 2012. “Going solar is a great way for local homeowners to make a difference,” said Mike Riley, executive director of The Environmental Center. “Solar helps families save money on their energy bills, prevent pollution by harvesting energy from the sun, and support Oregon’s economy by buying local. And that’s a win for everybody.” To be eligible for Go Solar!’s discounted prices, homeowners must first register for the program online at GoSolarCentralOregon.org. Once registered, a Go Solar! contractor will visit their home for a free solar site assessment and develop a solar system proposal. “Solar has never made more sense as a smart investment in your home and a great hedge against the rising cost of energy,” continued Riley. “The combination of solar panel prices at historic lows, Go Solar!’s discounts, substantial state and federal tax credits, and incentives from the Energy Trust of Oregon means that the average Go Solar! electric system has a simple payback period of 4 to 5 years.” Go Solar! is presenting free workshops in Bend and Redmond in October. Workshops will include an overview of residential solar energy and the Go Solar! program, as well as available incentives and tax credits. Go Solar’s local contractor partners will also be available to answer questions. Visit GoSolarCentralOregon.org for a complete list of workshop dates, times and locations. Go Solar! Central Oregon is a pilot program of The Environmental Center, in partnership with local contractors Sunlight Solar Energy and E2 Solar, Oregon solar manufacturer SolarWorld, Northcoast Electric, Bend Radio Group and Combined Communications.

“This home was specifically designed to allow the homeowner to age gracefully in place.” Architect: Cheryl Heinrichs Architecture Builder: JB Davis Construction LLC • Year Built: 2011
Address: 2211 NW Clearwater Dr. – Northwest Crossing, Bend There are few people who design their homes with an extended future in mind, so it is a delight to be able to include one in this year’s tour. The owner’s present life includes a variety of needs and loves that the home provides for, such as an office, space for playing music, room to exercise and easy access to
nature, but it is also designed for the future, when greater ease of maneuvering throughout the house may be required. There are no interior thresholds, including the shower entries; the halls and doorways are wide, and all doors utilize lever hardware. The home is also designed for minimal maintenance, with efficient heating and cooling systems, an active solar system, on-demand water heater, and a southern solar orientation that provides glorious daylight, even to the more private spaces. By making the interior walls partial height, daylight is pulled deep into the rooms on the north side via the transoms above the doors, deriving maximum value from the glazing layout that places 75 percent of the windows on the south walls. The clean aesthetics of the finishes, including NW madrone counters and flooring and natural plaster walls will provide a lovely, calming backdrop throughout the years.

Geothermal Harrison Crecraft | Senior Project Manager | Bowman Geothermal What is geothermal heating and cooling? It is not about volcanoes and geysers or energy production from deep steam or superheated water. “Little g” geothermal is about using the earth as a natural solar collector. Seasonal heating and cooling of the earth’s surface makes the ground ideal for storing summertime heat to heat us in the winter and for absorbing heat to keep us cool in the summer. Geothermal heat pumps are used to move the heat between your house and the ground. Geothermal heat pumps are much more efficient than air-source heat pumps. They can work efficiently even on the hottest or coldest days of the year because of the year-round moderate ground temperature. Water and antifreeze are circulated through plastic tubing buried in vertical bore holes, horizontal trenches, or sometimes in ponds. In the winter, cold water extracts heat from the ground, and delivers it to the heat pump, which concentrates the heat to deliver it to your house. In the summer the heat pump extracts heat from your house and circulates warmed water through the ground to shed heat. Heat Pump manufacturers are now introducing the next generation of heat pumps with higher efficiencies than ever possible before. Some also will provide hot water year round. Not only can geothermal systems cut total utility costs in half, a Federal tax credit in effect through 2016 can reimburse 30% of the cost of the entire heating and cooling system. In order for geothermal heating and cooling to work properly, it is essential that the heating and cooling requirements of the house are properly assessed and that the loop is properly sized. The important properties determining the loop size, in addition to heating and cooling requirements, is the ground temperature and the thermal conductivity of the soil or rock. Although the deep ground temperature is normally uniform and close to the mean annual
air temperature, ground temperatures in trenches are sensitive to depth. In addition, some areas receive additional heat by ground water circulating within deep faults or volcanic zones. Thermal conductivities for common rock types are adequately known, but for soils, conductivity depends not just on density, clay, and sand contents, but also on moisture. Dry light soil has half the conductivity of dense moist soil. It is important to have a system sized by an installer familiar with the local conditions. Local accredited installers and much more can be found at the International Ground Source Heat Pump Association at www.igshpa.okstate.edu.

GLOSSARY OF GREEN HOME TERMINOLOGY
Glossary adapted from Good Green Homes: Creating Better Homes for a Healthier Planet With permission from the author, Jennifer Roberts. www.jenniferroberts.com www.goodgreenhomes.com
Adaptable building
A building than can be readily remodeled or re-configured to meet an occupant’s or community’s evolving needs.
EPSTM
EPSTM, brought to you by Energy Trust of Oregon, is an energy performance score that helps you assess a home’s energy consumption, energy costs and carbon footprint.”
Advanced framing
Design and construction techniques that significantly reduce the amount of material used to frame a building. Includes strategies such as studs placed 24 inches on center; fully insulated corners; insulated headers; engineered wood products; and roof or floor trusses.
Engineered wood
Air Changes per Hour (ACH)
Air Changes per Hour, is the total volume of air in a space that is exchanged over in hour.
Building products, including beams, framing studs, and floor and roof joists, made from wood fibers bound with adhesives. The wood typically comes from plantation-grown trees, thus reducing demand for old-growth trees. In general, engineered wood products result in less wood waste than solid sawn lumber products.
Alternating current (AC)

Phenol formaldehyde is roughly 4-10% as volatile as Urea-based glues. Phenol is typically used for exterior materials like OSB, engineered lumber and exterior grade plywood.
Geothermal
Energy produced by the internal heat of the earth. It is the normal temperature of the ground at shallow depths. Geothermal energy uses this stable temperature to cool your house in the summer and heat it in the winter. Channels are dug into the ground and pipes laid to circulate water (or refrigerant) throughout the house – one direction in winter to draw in the warmer water and the other direction in the summer to send the heat outside and bring in the cooler temperature water

Impervious surface
A surface that water can’t pass through.
Double-glazed window
A window with two panes of glass separated by an air space. Compared to single-glazed windows, double-glazed windows significantly reduce heat and sound transmission. Some double-glazed windows contain a gas such as argon or krypton in the air gap to provide additional insulation.
Incandescent light bulb
A light bulb that consists of a filament inside a glass bulb. Passing electric current through the filament causes it to heat up and produce light. Standard household light bulbs are incandescent bulbs; they are very inefficient, wasting 90% of their energy as heat instead of useful light.

Pascal
A unit of measurement of air pressure
Passive solar design
A building specifically designed to collect and store the sun’s heat, and release that heat into the interior spaces to help warm the rooms naturally. Depending on the design and climate, passive solar heating can be the sole source of heat for the building or can be supplemented with a heating system.
Tubular skylight
A circular skylight that’s much smaller than typical skylights, designed to illuminate interiors with daylight while keeping out excessive heat. It consists of a small, roof-mounted dome attached to a tube lined with reflective material. Light is reflected down the tube, and is transmitted into the room through a translucent ceiling fixture.
U-factor
Indicates how easily heat will pass through a construction assembly, such as a window. The lower the U-factor, the lower the rate of heat flow.

Volatile organic compound (VOC)
Post-consumer recycled content
Products that have been used and discarded by a consumer and are then reprocessed as raw material for a new product.
A class of organic chemicals that readily release gaseous vapors at room temperature. VOCs occur naturally in many materials, and can also be manufactured and added to materials and products. VOCs are released (“offgassed”) into a home by common furnishings and building materials, including many types of particleboard, paint, solvents, carpets and synthetic fabrics. Exposure to VOCs can cause symptoms ranging from short-term nausea, eye irritation and headaches to more severe, longer-lasting effects.
Radiant barrier
A material installed in buildings to reduce summer heat gain (and, to a lesser extent, winter heat loss). Radiant barrier products typically consist of a thin sheet of a reflective material such as aluminum, attached to a substrate such as plywood, oriented strand board or kraft paper. The product is typically installed in a home’s attic to reduce the transfer of heat from the roof into the home.
Whole-house fan
Radiation
The transfer of heat from a warm object to a cooler object by means of electromagnetic waves passing through air or space. When you stand in the sun, your skin is warmed by radiation. When you stand next to a cold window, your body radiates heat to the cooler window.
A powerful fan mounted in a ceiling opening, used to pull air through the home and exhaust it out the attic and through the roof vents. It provides air circulation and cooling in climates where days are warm and nights are cooler, and can often reduce or eliminate the need for air conditioning. A wholehouse fan is typically used at night to pull cooler outside air into the home through open windows, and to vent warm air through the attic and roof.

“Embrace life’s changes and design a home that is flexible in its use over time.” Co-Designers: Jason Offutt and Marayd Allen • Builder: Craig Johannesen Year Built: Under Construction
Address: 18830 MacAlpine Loop, Bend What do you do when the family structure changes, creating different needs from your home? You embrace the change and design a home that is flexible in its use over time. Working intimately with the designer and builder, that is what these owners have done. The 2-story layout allows them to close off the upstairs when their “kids” are not home, focusing their daily living on the main level where they can enjoy the breezes moving through the surrounding trees. That is, of course, when they are not enjoying the mountain bike trails on the adjacent “Phil’s Trail” system. Proximity to these Forest Service trails was
a major deciding factor for the location of the home, and an appreciation for the integrity of the lot’s land and trees influenced their efforts to minimize the amount of development the property received. The design encourages daylight into all high-use areas, creating a visual connection to the beautiful outdoor environment. Knowing that trees can also become a fire hazard, Insulated Concrete Forms (ICF’s) and concrete roof tiles were used to protect as well as insulate the home. A recipient of the Energy Star New Home Verification, an energy efficiency program that addresses systems, products and materials, this home should satisfy their needs and fulfill their dreams for quite some time. The home’s masonry heater is a must see.

Home Energy Analyst Training at COCC It’s no secret that the building profession has become increasingly competitive in our challenging economy. One way for building professionals to stay competitive and keep business leads coming in is to include home energy efficiency services on existing homes as part of your product and service selection. COCC’s Continuing Education program offers the classroom and field training to prepare building professionals for the Building Performance Institute’s (BPI) ‘Home Energy Analyst’ certification exams. Participants in the course learn to use testing equipment to provide specific energy utilization information including calculating a home energy use score. Students spend six days learning the fundamentals of building science with partial days in the classroom and partial days practicing energy testing skills in local homes under the guidance of instructor Rod Street. Following the classroom/field learning, candidates will take certification exams proctored by a BPI proctor in order to become certified as a ‘Home Energy Analyst’. The Home Energy Analyst training has typically been available only in larger cities, so taking a Central Oregon class will save travel time and money. While many other providers of this course offer online options, COCC’s class has been intentional to keep a strong hands-on field learning component, which translates to high retention when students finish the class. COCC’s next course begins October 24 and meets October 24, 25, 26, 31, November 1 and 2 from 8:00 am to 5:00 pm at COCC’s Bend campus and alternate locations for field sessions. The deadline to register for this training is October 12 and cost is $1550, which does not include BPI testing fees.

“A safe and nurturing sanctuary; rooted on the earth and soaring to the sky, evoking an expansive, exalted state.” Designer/Builder/Homeowner: Don O’Brien, Year Built: 2012
Address: 1761 SW Troon, Bend One way to achieve a level of environmental sustainability in a home is to share resources and space, and when the design of that space is done well, it can also facilitate a sustainability of spirit. This is the ultimate
intention behind the design of this home. Three master suites provide personal domains while the main floor is shared by all, creating a collaborative living experience. This connection and collaborative spirit is reflected in the structures and systems throughout the house, beginning with the approach to the house via the elevated entry walkway, which the designer calls a “skybridge.” This bridge connects the land to the structure of the house, but it also serves as the first step of a journey in which the designer hopes that the individual is able to connect with a larger sense of oneself. The small foundational footprint allows for greater use of site for present community events and future gardens that will be irrigated with water from a 2,500 gal. rainwater collection tank. A tremendous use of day lighting, with triple pane glazing, create an extraordinary quality of light; 10 inch walls provide comfort, and the minimalist approach to surface materials create an overall calming environment.

“The Desert Rain House is rooted in its environment and responsive to its inhabitants.” Designer: Tozer Design Builder: Timberline Construction• Year Built: Under construction
Address: 22 NW Shasta Place, Bend Some homes support sustainable living choices; this home requires that the owners truly walk the thin green line in order to achieve what is the most rigorous certification standards in sustainable design and construction to date. According to the team behind the creation of this home, it will be “net zero energy, net zero water and will meet the rest of the Living Building Challenge (LBC) requirements for LBC certification as well as achieve LEED Platinum certification.” The homeowners must not only document their compliance throughout the entire
design and construction process, but must track the home’s performance over the course of a year before receiving the Living Building Challenge certification. This project models a new level of energy efficiency and sustainability that the owners hope will serve as a learning tool for others, in a design that is warm and welcoming for all. “While not fully ADA compliant, one of the driving factors of the project is to make the home and the grounds as accessible as possible for friends who may have a physical disability.” Open, artfully aesthetic, and practical in how the spaces are to be used, the Desert Rain home intimately engages with its environment and calls all that enter to be mindful of how they engage as well.

Building Relationships While Rebuilding a Home: a Story of Sustainability by Gina Meredith Carol Mergenthaler never saw herself as an environmentalist. She would not have described her daily living practices as being particularly “green.” Then she and her husband decided to remodel their 1970’s “clunker” of a house and she began to see that there could be more to this idea of sustainability than she thought. Even now, she is reluctant to say that this remodel project was an example of green construction because the home lacks any of those details that have become synonymous with green design- things like solar panels, passive solar orientation or concrete radiant floors. However, it was the deconstruction process of the home and the reconstruction choices made when rebuilding that combined to express a level of sustainability that was real, practical, affordable, and just plain delightful for the greater sense of community it both fostered and benefitted. The process began with gutting the interior. Out came the carpet, pads, trim, hardware, appliances, vanities, showers, burnt orange toilets, cabinets and glorious gold switch
plates, as well as some exterior decking. A “free to a good home” advertisement was placed in the Nickel Ads for the decking, which got a positive response from a resourceful couple that was building a cabin in the Strawberry Mountains, east of John Day. Upon arrival, they saw the other “treasures” and, in the spirit of the project, jumped in to help with the deconstruction. Later, Carol and her family took their good natures and the rest of the deconstruction goods, from the burnt orange toilets to the gold switch plates, on a trip to the cabin in the Strawberry Mountains. She describes it as a wonderful experience in sharing; “We built a relationship with those folks and still exchange Christmas cards, to this day.” Although Carol and her husband did not begin the project with the intention of being sustainable, that is just what they were doing by passing on their outdated “treasures” to others who were thrilled to give them new life, thus reducing the project’s construction waste. Everything else that was still useful was donated to the Habitat for Humanity ReStore in Bend and
14 -GREEN & SOLAR HOME TOUR 2012
when it came time to make purchases for the remodel, they returned to the ReStore, keeping the reuse cycle going. Finally, they made two trips to the dump in a 4x8x5 trailer with what could not be recycled or reused, calculating their cubic feet of construction waste to be a mere 160 cubic feet for the deconstruction of the interior of a 1,675 square foot home. One of the surprises of this project was the discovery of a 2x8 tongue and groove Douglas fir subfloor that had been hiding under all that old carpet. The people at Cutting Edge Flooring (no longer in the area) worked with Carol and her husband to refinish the floor until it was smooth underfoot and glowing with warmth. Now, when they spend time at home, they feel surrounded by the satisfying knowledge that their remodel was sustaining in many unexpected ways, for the family, for the land and for their now greatly extended community. Practically speaking, Carol’s family saved money by reusing what they could and
putting materials into the reuse stream for others. They saved dollars as well by reducing their volume of construction waste that went to the dump. Their newlyinsulated attic, floor and walls will help reduce their home heating bills and add to the overall feeling of comfort. “Being sustainable,” Carol has learned, “isn’t an end-product to achieve or a competition to see who can be the greenest.

GREEN AT A GLANCE “A passive solar home that outperforms calculated 3RD PARTY GREEN BUILDING CERTIFICATIONS EPS Score 36 Advantage Platinum energy calculations; embracing the owners with gracious, Earth LEED Platinum ENERGY STAR Home healthy living at a fraction of normal utility costs.” Oregon High Performance Home ®
®
Architect: Lawrence M. Schechter, LEED AP Builder: SolAire Homebuilders • Year Built: 2011
Address: 64970 Gerking Market Rd, Tumalo The design of this award-winning home (2011 COBA Tour of Homes: Green Building Award, plus 5 others) incorporates many notable details, including a passive solar design; 4,000 watt PV solar electric system and solar hot water system; Ground Source Heat Pump and Geothermal wells. No matter what the season, the house maintains a comfortable range of 65 to 72 degrees- due primarily to passive energy- and the first four months of operation
resulted in a net credit from the utility company. Projections are that the annual utility costs will be 40% below the calculated total. Its list of certifications is equally impressive (see Green at a Glance), but it is the livability and simple, natural elegance of the home that the owners love- as well as the savings. In the owners’ words, “this house provides better living than we expected; greater comfort and is more affordable to live in than we imagined.” For this, they point to the initial creation of a design-build team, which included Architect, Lawrence Schechter, SolAire Homebuilders and the owners. It takes a village to create this caliber of sustainable design.

“ ‘Exceeding’ is about believing that style and alternative energy systems can work hand in hand to create quite a home.” Designer: The Shelter Studio • Builder: Black Rock Construction • Year Built: 2012
Address: 14900 Miramonte Ct. Brasada Ranch, Powell Butte Actually exceeding the energy efficiency requirements of Earth Advantage, this home has received a Platinum rating- the highest available in the Earth Advantage certification program. For those who are not familiar with what is entailed in reaching this level of certification, here are some words from Earth Advantage Institute. “Our certification is a holistic program based on building measures in five categories; water,
land, energy, health and materials. The program incorporates systems and materials that create superior indoor air quality, use natural resources responsibly, protect land, and lower water usage. Combining these benefits with the energy efficiency standards of ENERGY STAR ensures that Earth Advantage certified homes exhibit superior performance and environmental responsibility compared to traditionally built homes.” Many of these factors will not be visible in the home; what you will probably be most aware of are the beautiful surfaces from floor, to wall; counter to cabinet and the gracious flow between indoors and out. There is one more detail that you will not be aware of, which sets this home above many others- the attention to recycling jobsite waste. According to the builders, Black Rock Construction, “One hundred percent of the metal, drywall, shrink-wrap, and plastic waste were recycled.” “Exceeding” is about believing that style and alternative energy systems can work hand in hand to create quite a home.

“This project is low-tech and low-cost for high-yield.” Designer/Builder/Owner: David W. Kuperstein Year Built: 2011
Address: 2202 SE Vickie Dr., Prineville It all started with the vegetables. Because they live in a region that has such a short growing season, the owners decided to build a series of cold frames that would allow them to grow more food. Those led to adding a
greenhouse to the shop, which inspired the building of a passive solar sun/garden room addition to their home that also houses a hot tub and a small woodstove. Sound basic design and implementation have created a comfortable, year-round space that helps heat or cool the home, depending on the season. Tiled, eight inch concrete walls and a stained concrete floor serve as heat sinks, while operable clerestory windows allow excess heat to escape. “Temperature gain/loss can be adjusted with shade-cloth, insulation or passive and active ventilation.” Using simple practices, the owners have realized a reduction in their heating costs of 5% over the course of the year. “Not huge,” says the owner, “but hey, it’s free.” The cost of the structure was also reduced by choosing to use recycled lumber from Pakit and windows from the Habitat for Humanity ReStore, both in Bend. This project demonstrates the realization of sustainability that is accessible on several levels- being financially feasible, as it feeds the body and sooths the spirit.

Greener and Leaner: Teaching an Older Home New Tricks Bundled in parkas and loading the final remnants of our firewood stash, we vowed it would be the last winter of our dependence on wood heat to keep the utility bills manageable. I had to remind myself that my “new” home was now older than Justin Bieber. The original heat pump and furnace could barely wheeze out a breath of warm air without sending the electric meter into a whirling frenzy. But replacing the entire heating and cooling system presented a daunting financial challenge. And exactly how do you retrofit an older home? So I was intrigued when I ran across a flyer for Clean Energy Works Oregon (CEWO). With promises of a possible 30 percent savings with an
Louise Hawker
energy efficient upgrade, plus low-interest loans, it was a one-stop shop for my needs. I signed up and was soon scheduled for “the blower door”—whatever that meant. I envisioned us and the cats velcroed to the wall in a negative air flow environment.
In reality, the blower door—the star of the home performance test—helped the project specialist identify air leaks and other deficiencies in the “house as a system.” She also explored the attic and crawl space to assess insulation and duct work. Yep – I could expect to realize 30 percent savings, plus rebates and tax credits, with a new system. And hey, how about replacing the hot water
heater that’s old enough to vote? I was sold.
With summer temps in the 90’s, the contractors started work at 6:30 most mornings. While it was a bit unnerving to encounter an installer in the hallway on the way to my first coffee, I was impressed with the project’s rapid pace. The heat pump, furnace and water heater were installed in one day. Sealing and insulating duct work, caulking air leaks, weatherstripping, insulating the attic to a whopping R50, correcting the exhaust and attic ventilation, was all accomplished in about one week. The blower door returned and revealed some remaining areas of improvement. More tweaking,
and a final test determined that our home is now snug as a bug in the proverbial rug. While the retrofit was under way, we ushered some of the resident water hogs out the door. An uncooperative toilet was replaced with a lowflush model. An ancient clothes washer spun its last and a new high-efficiency washer took its place. While we will always manage the heating and cooling system conservatively, it’s reassuring to have a greener home that will increase our comfort, lower our energy bills, and be kinder to the environment, for many years to come. www.cleanenergyworksoregon.org/

The Living Building Challenge: The Desert Rain Project The Living Building Challenge is the world’s most rigorous green building performance standard. It is both a philosophy and certification program, challenging building teams to embrace regional solutions in seven areas, or ‘petals’: Site, Water, Energy, Health, Materials, Equity and Beauty. Projects must be in operation for 12 months before they are eligible for certification. These are the worlds greenest buildings and will never get an energy or water bill again. The Red List, an imperative of the Materials Petal, is intended to eliminate the most toxic chemicals, from a human and ecological standpoint, from the built environment. Building materials may not contain these chemicals, must come from responsible sources, and from within a relatively short distance. Chemicals, like formaldehyde, PVC (polyvinyl Chloride) and CFC’s are present in our standard construction products. Water pipes, electrical wire, particleboard and plywood are a few of these. The challenge is to build with alternative materials; not an easy task. In Bend, one of the major challenges of our dry climate, is the Water Petal. It posits that “100% of occupants’ water use must come from captured precipitation or closed loop water systems, purified without the use of chemicals.” This requires a large storage tank to capture water when available in winter, for use in our generally dry summers. In addition 100% of storm water and building waste water must be managed onsite, purified and reused, often for landscape maintenance. Waste management and the carbon footprint of the construction process are also subject to stringent standards. The Living Building Institute calls the Challenge “a visionary path to a restorative future”. We are privileged to have the visionary Desert Rain Project, built by Timberline Construction, on the 2012 Tour. There are currently only three projects, worldwide, that have achieved full ‘Living Building’ status by meeting all the Imperatives. Finally, from the Challenge Guide: “Imagine a building designed and constructed to function as efficiently as a flower, a building informed by its bioregion’s characteristics, and that generates all of its own energy with renewable resources, captures and treats all of its water, and operates efficiently and for maximum beauty.” We are proud to say imagination is becoming reality in Bend.
