What is Green Building? A Whole House Approach is a Key Element
A Whole House Approach considers the building as a system with interrelated parts. A first step would be to have a blower door test conducted to determine the locations and extent of air leaks. Heat generated inside will seek the colder space outside any way it can. Money can be better spent on sealing and insulating, upgrading the home's overall performance, before adding a new expensive component like an elaborate photovoltaic system. With this approach, the size and expense of a solar system (if desired) can be moderated to fit the improved building system.

What is Green Building? It's About Performance
Most of the buildings we live and work in could use some help--ranging from a tune-up to an overhaul--to improve their performance. The benefits of a better-performing building include lower heating/cooling costs, higher comfort level, and less negative impact on the environment.
The average useful life of a furnace is about 15 years, with decreasing efficiency over time. As much as 30% of the warm air probably escapes under the house or in the attic before it warms us due to unsealed, leaking ductwork.
Many buildings built before the last decade have what would now be regarded as inadequate insulation to conserve the warm air generated by the inefficient heating system. And there are a myriad of air leaks that could be sealed where plumbing and electrical components penetrate into the living space.
Single pane windows (homes built as recently as 30 years ago have these) and unsealed crawl spaces promote condensation and interior moisture, which can lead to mildew and mold in the home. There are health risks associated with these conditions.
These are but a few of the most obvious places to start the tune-up or overhaul your building needs. Contact us to schedule a complimentary evaluation of your building's performance.

What is Green Building? Thoughtful Shopping for Materials is a Key Element
The money spent at the corporate outlet leaves the local community. The transportation involved in getting the materials from outside the U.S. to your neighborhood consumes a lot of energy and produces a lot of CO2 emissions.
We are fortunate here in Sonoma County to have several local family-owned building materials retailers that are competitive in price with the corporate giants. Having grown up in a family that operated a business like that, I rarely darken the door of the "big box" store. The dollars spent in a locally-owned business circulate among friends and neighbors, rather than leaving for distant corporate headquarters.
I recently finished a kitchen facelift including new flooring. I was able to purchase American-made laminate flooring with almost all recycled content at one of the locally-owned suppliers at a very competitive price. That transaction supported American jobs, provided a healthy, low-carbon footprint improvement to the home, and circulated dollars in the local community.
This is just one small example of how thoughtful materials selection can have a ripple effect moving toward sustainability, both globally and locally.

CAL GREEN--California Green Building Code 2011
Some specific requirements for every new building include:
--Reduction of water consumption by 20%.
--Diversion of 50% of construction waste away from landfills.
--Installation of healthier, low-toxic building materials.
--Requires separate water meters for nonresidential buildings indoor & outdoor water use.
--Calls for moisture-sensing irrigation systems for larger landscape projects.
--Mandates inspections of energy systems (heat furnace, air conditioning & mechanical systems)
for nonresidential buildings over 10,000 square feet.
The California Air Resources Board estimates that greenhouse gas emissions may be reduced by 3 million metric tons in ten years. Property owners can label their facilities as CAL GREEN Compliant after passing inspection, without an additional third-party verification. Approximately 40 local jurisdictions already have voluntary Green building standards in place. CAL GREEN will provide a consistent, state-wide mandatory code, setting a high standard for the entire country.
Thanks to California Green Solutions for the above summary. We look forward to working with the new code in the coming year. Contact us for assistance as you develop your building project.

Sonoma County Energy Independence Program Gains Momentum
I asked how the program is going, and was told that since its inception last March, nearly 600 applications have been accepted with projects underway or completed. Other local governments in the Bay Area are developing their own versions of this program as well.
I am currently working on a project on an older home adding floor insulation, replacing the outmoded forced-air heating system with a 95% efficient furnace and all new sealed ductwork, and replacing all the old wood sash with new dual-glazed windows that have weatherproof cladding on the exterior and wood showing inside.
More information about the SCEIP can be found on their website www.sonomacountyenergy.org.

Financing Is Now Available for Greening Your Home or Business
Improvements must be permanently affixed to the property, and can include (but are not limited to): high efficiency windows, solar and/or tankless water heaters, solar panels, upgraded wall and roof insulation, "smart" irrigation systems, and high efficiency HVAC systems. Working with their contractor, property owners determine the scope and costs of proposed retrofits and apply for funding from the county. If approved, the county pays the up-front costs, places an assessment lien on the property, and the owner repays the county through the property tax system over a 5, 10, or 20 year period. If the property is sold, the new owner takes on the obligation to repay for the improvements.
Contact Tom Trent Builders (707) 865-1250 or tom@tomtrentbuilders.com for more information and to schedule a free consultation. www.sonomacountyenergy.org is the official website for the program, where you can get all the details and application forms.

What is Green Building? Resource Conservation is a Key Element
I want to focus on a couple of Sonoma County family-owned businesses that are not only suppliers of Greener products, but also leaders in pointing the way toward a Greener future in the construction industry.
With respect to concrete, the production of Portland Cement is perhaps the most heavy carbon footprint of any building material. The aggregates (sand & gravel) have to be mined from the earth and processed to be of any use. Austin Creek Materials in Cazadero operates a quarry, extracts gravel from a creek, and processes and sells aggregates and concrete. Several years ago, this company received national recognition for its careful environmental practices regarding the fish habitat in Austin Creek. More recently, it is working with some local entrepreneurs to make ecologically safer concrete available to the industry and the public. This new product will contain much less Portland Cement (substituting flyash and other substances), and much less natural aggregates (substituting crushed recycled old concrete). It costs more to produce and purchase than standard concrete, but its environmental impact is much lower.
Looking at forest products, the old-style logging practices resulted in clear-cutting, erosion, and loss of animal habitat. While these methods are on the decline, the real change is happening in forests that are managed and harvested in ways that are environmentally responsible. The Forest Stewardship Council is an international non-profit organization that sets standards for these new approaches and certifies specific companies that are marketing their products as having been harvested in a sustainable way. Trees are individually selected for cutting and are replanted in a biodiverse manner. Each log is tracked in a "chain of custody"--from the forest, to the mill and finally to the retail supplier--to certify its authenticity. In Sonoma County, the principals in Mead Clark Lumber Co. have created a wholesale business--Natural Forest Distribution--that specializes in making FSC certified products available for the West Coast. Again, they cost more to produce and purchase, but the long-term benefits for the forests--which absorb CO2 and provide animal habitat--are incalculable.
Contact me and let me help you plan your new home, addition/remodel project or repair job utilizing these locally-available Green products and materials. We can build a first-quality project that helps improve the health of the local economy and the planet.

The Inauguration and the Green Building Academy--a Double Dose of Inspiration
He has called upon every citizen to be part of a new "era of responsibility" to each other, our communities and country, and the planet. His challenge to "pick ourselves up, dust ourselves off, and begin again the remaking of America", saying "we are ready to lead" once again is exactly the attitude that is needed in these times.
This remaking is already underway here in Sonoma County. I participated in a meeting of the Advisory Committee for the Green Building and Design Academy at Montgomery High School in Santa Rosa yesterday as well. A former client--for whom I built a solar-powered house seven years ago--teaches there and initiated this unique program. It has 30 sophomores, more than half of whom are "at risk" academically, socially or economically.
After only one semester in the program, these kids have become passionate about learning because they see a future for themselves working in Green technology and business. Some want to be hands-on technicians, retrofitting existing buildings for energy-efficiency or installing solar systems. Others have already set their sights toward higher education to learn marketing, engineering, construction management or computer science, all with a Green emphasis.
Some of these students who could barely express themselves last fall now go out to speak publicly before adult community groups telling about their reasons for getting involved, their personal difficulties in school in the past, and their new plans for the future. This program is the only one of its kind and I am thrilled to be a part of it. It is evolving spontaneously in response to a real need and is a guidepost to a hopeful future.

Green Building Creates Jobs, Saves Energy and Money
This is a ray of hope that the upcoming federal economic stimulus, aimed at dealing with the present financial crisis, will include elements that will not only circulate dollars but also promote positive change for the environment. Who can argue with the need for healthier schools and more energy-efficient public buildings?
On an individual level, nearly every existing home, business or workplace could be "greened up" to improve its energy performance and promote a healthier indoor environment. Change of any kind starts at home, at the micro level, doing what we can with what we have. As a Certified Green Building Professional, I can help you develop your "to do list" to get started (in the words of David Johnston) "changing the world one room at a time".

How Big is Your Footprint?
The quiz measures four categories of footprint: Carbon (home energy and transportation); Food; Housing; and Goods and Services. From the answers you give, the quiz calculates a sustainability index that is graphically shown by how many planet Earths it would take if everyone lived like you.
There are also suggestions on how you can live a more sustainable lifestyle.
If you would like a free consultation about changes that can be made to your home or office to
"green it up", I would be happy to talk about some specifics with you.

Living Better in Sonoma County--the Coast
Wind-driven rain can find ways to enter a building causing damage to the structure and interior. Special care and methods (that would be considered extreme elsewhere) must be taken when installing windows, flashings and exterior siding and trim to prevent troublesome leaks. Having learned the carpentry trade in this environment as a young apprentice, I became aware early on of the unique problems one can encounter when building at the Coast.
The only metals that perform well as fasteners and flashings are stainless steel and copper...forget about galvanized steel anywhere near the Coast. This is because of the highly corrosive salty moisture in the air near the ocean. These materials are costly to purchase, but take no longer to install and are well worth the expense to prevent problems later.
There are two projects at the Coast featured on my website www.tomtrentbuilders.com .

Living Better in Sonoma County--Russian River Area and the Redwoods
I lost count long ago of the decks and stairs I have replaced because the Douglas Fir framing lumber had been left unsealed, allowing moisture to be absorbed and rot to develop. Often the Redwood decking was still relatively sound, but the structure underneath had become unsafe. The use of pressure-treated Fir lumber has helped solve this problem, while creating others. Workers should wear dust masks and gloves when handling these materials that contain toxins, and special measures need to be taken for scrap disposal. In recent years, these materials have become more user-friendly, containing less harmful chemicals. Hot-dipped galvanized or stainless steel hardware and fasteners are necessary to resist the corrosive effects of treated lumber.
There are a variety of alternatives to using precious Redwood for decking. Composite materials, made from recycled plastic products, require virtually no maintenance. Some manufacturers provide handrail components as well as decking.
Interior problems of mildew and mold are often caused by moisture condensation. We generate humidity indoors with normal activities like cooking and showering. When this warm, moist air makes contact with a colder surface--like the drywall in an uninsulated wall or the glass in a single pane window--condensation occurs, promoting the growth of mildew and mold. Upgrading the home's insulation, replacing old windows with dual-glazed units, and installing bathroom fans are basic steps that can be taken to save money on heating costs and improve indoor air quality.

Living Better in Sonoma County--the Inland Valleys
The southern exposure of your home can be a source of uncomfortable heat in the summer and welcome warmth in the winter. Orientation of a new home or addition to take advantage of passive solar shading and heating is too often overlooked. A south-facing room with large windows needs several elements to make it work well.
When the sun is high in summertime, wide roof overhangs and shades will keep the house cooler. During the winter, when the sun is lower, the sun's rays can help heat the home, especially if they shine on a floor with thermal mass, such as tile over concrete. This material absorbs solar heat and retains it over time. Taking advantage of this natural approach to heating and cooling will make your home more comfortable and energy-efficient. A super-insulated (R-25 walls, R-50 ceiling) house that is oriented for passive solar can cut energy costs by up to 50%!
This is one example of how a Green Building approach can be utilized, whether it is new construction or remodeling. I can suggest others specific to your situation.

Winter Is Just Around The Corner
Now is the time to check weatherstripping and replace if it has gotten brittle over time. Furnace filters should be changed to maximize efficiency. Inadequate attic insulation is a major source of heat loss as are single pane windows.
Solving these problems is a service I provide that can increase your comfort level and save you money as well.

Greening Your Home Has Benefits
Buildings are the largest source of CO2 emissions, far surpassing tranportation and industry. 70% of the homes in California were built before 1978, when the need for energy conservation became so apparent that the Energy Code was adopted (Title 24). And the majority built since then are not energy-efficient by today's standards. The quality of indoor air, where we spend most of our time, is 2-4 times worse than outdoors.
These facts lead to the compelling need to take action to make our existing--as well as new-- buildings cost less to operate and be healthier places in which to spend time. Green building is not just about solar and alternative energy, it is also about saving money and improving overall health. There are a wide variety of steps--from small to medium to large--that I can suggest for your specific situation to improve your quality of life and protect our environment. Here are but a few examples:
95% of the energy used by incandescent light bulbs generates heat, not light. Compact fluorescent bulbs now come in warmer color shades and save money every month.
Weatherstripping and sealing to prevent heat loss through uncontrolled air infiltration is another low-cost way to reduce energy costs.
When replacing carpet or other flooring, shop for products that contain less harmful components than the old standard ones. Offgassing from underlayment and floor coverings is a major source of bad indoor air quality, and it continues for years. There are viable alternatives out there.
When replacing your water heater, appliances, or HVAC system, get advice on how to improve the energy efficiency and performance of these big ticket items. The labels can be confusing and/or deceiving.
If you decide to add to or remodel your home, I can work with you to improve your building's energy performance as well as your family's health by implementing some Green Building approaches. The benefits you will experience will continue long after the project is complete.

My sister, Billy Trent, loaned me her digital camera and spent countless hours processing and downloading several hundred pictures onto CD’s, setting me up with an on-line photo service, and encouraging me to make our family’s business tradition part of my presentation on the Web. I ended up devoting a special page to that aspect. For it was my father and grandfather who taught me the meaning of work and service in business.
I had looked into the “create it yourself free” website services offered by various internet companies and was not satisfied with those. I knew I would need professional help to create something customized and special to get my message out there. Then lightning struck when I met Buffie Harris, who operates Design Orbit. We immediately hit it off and after our first get-together, I knew I had found the perfect person to create the website. She listened to me as carefully as I do with my clients, to get an intuitive feel for what I wanted. Her work consistently exceeded my expectations.
