Big Changes!

February 15, 2014

On February 3, I closed the doors of GreenBridge Architects and rejoined DeStefano Architects in Portsmouth, NH as the Manager of the Residential Studio. It’s an exciting time to be returning. The firm is growing their staff and the reach of their work. The residential studio is an exciting place for me to expand and use my knowledge of green design and the changing practice of residential and especially coastal design. I also get the added benefit of working with an amazing team of brilliant architects.

Lisa DeStefano and I have a long history and friendship. I first joined her firm in 2002 when I moved to the area. I worked with her for over 5 years, and learned volumes about the design of fabulous homes, coastal design…and being from the Midwest, I also had a lot to learn about sloping terrain! Throughout my launching GreenBridge and the ups and downs of having my own practice, Lisa has been a steady resource and supporting friend. I treasured her input and learned from her processes. She is one of the cornerstones of my career and I’m thrilled to be working with her again.

A few of my favorite projects from my DeStefano years…

I’ve had a wonderful six years at GreenBridge and have been blessed to have some of the most amazing projects and clients. I’ve loved the process of working with them to make their homes more beautiful and work better for their families. I’ve also made some great friends, both clients and allied professionals. Lisa Kawski, Hilary Ward, Sarah Holden, Holly Gagne and Elena Bachrach were some of those allied professionals I met along the way, who became my friends for life. Thanks guys!!

I hope to continue writing the greenbridge blog. At its origin, the name GreenBridge represented the connection of the architect, clients, designer, builders and systems to build great buildings. This concept continues to define my work, so although the firm will not continue, the greenbridge concept (and blog) will.

I hope that you’ll contact me at my new digs. We’re right next to Starbuck’s in Portsmouth (and within spitting distance of 2 other amazing coffee/pastry shops). When you’re in the area, I’d love to meet you for a quick cup.

Best wishes for a healthy and happy year!

This month has been a milestone for GreenBridge and The Riverview Company.  After almost 5 years of being in business, we have moved into our new studio space! I wanted to give you a tour of our new space and share its history. Our little barn building was built in the late 18th century. When we first moved to our house, this out-building was nearly falling down the hill to its rear and was 11” out of plumb. It was all potential, but my husband Steven and I loved it at first glance.

It’s been nine years and slow going construction-wise, diversions like our toddler, then a new baby, challenging careers, LEGOS… all were in collusion to the barn not getting finished. For the most part I didn’t think about it and have made a small office next to the kids’ bedrooms work. Steven (my husband and business partner) pressed on, slow but steady. Within our first week in the house, he raised the rear of the barn and installed new foundation piers. As time went on, he built out the interior of the first floor for his cabinetry shop and repaired the clapboards and trim on the exterior.

He built an amazingly WIDE stair to the second floor space, with careful detailing that gained us a dry storage shed below the stairs.

Steven built a beautiful conference table using salvaged lumber from a 17th century Amesbury Point Shore structure, a piece I will always treasure.

I’m thrilled to be in the space and can now testify more strongly than ever to the power of design. This space, so perfect for me and my work, is conducive to happy production, collaboration and creativity.

The Front Door

March 21, 2012

I was so excited to see Denise’s blog this month, Façade Face Lift. I love doors and entryways; we get a strong impression of the building or home from the front door. Entries are your first interaction with your home after being away, or for your visiting guests as they arrive to enjoy your company.

55 Cliff_exterior_1

One of our newest additions in Wellesley and one of my favorites.  Our client loves the special detail of the small overhead light that is activated by a motion-sensor – perfect for key-finding.  Construction by The Riverview Company.

Many homes have entry design challenges that fall under a few categories. Do you recognize your own home in any of these scenarios?

1. Come on in, but please don’t look. Nobody uses the front door, and the back door is ugly and doesn’t work. This item is especially prevalent in older homes built before most everybody had cars. Once most people had cars and garages, the closest door to the drive, often a small back or side door next to the kitchen, became the most used door for the house.

IMG_3248

This was the family and guest main entry, hidden behind the garage. The door is right next to their Eating Area table.

A new generous entry is in keeping with the rest of this lovely Wellesley home. Our client filled her window boxes as soon as they were finished.  Construction by The Riverview Company.

2. Where’s my right boot? No easy storage at the family’s entry. The word ‘easy’ is important here. If you and/or your family are normal, shoes, coat, keys and purses will be deposited on the first surface available. Thoughtfully designed storage with habits and lifestyles in mind makes a big difference. I like to design hooks and a kick-under bench, but with a closet to shift items as items pile up on the hooks and under/on the bench.

IMG_3758

Taken from the web….but most of us can relate.  except for the mini-well (?)

Mud Room_2

For this new basement entry, we added lots of storage with hooks, a closet, open shelving and a lift-top bench.  Construction by The Riverview Company.

As part of this addition, we created a generous formal entry space with large closets.  Construction by The Riverview Company.

A small custom built-in with cubbies and a lift-top bench where space was limited.  Construction by The Riverview Company.

A free-standing storage system can work wonders.  These are from Pottery Barn.

3. Hello? Can’t find the door or don’t know which one to approach. This is one of those challenges that we don’t think of until we have visitors and think about our home from their perspective. If you need to give directions to the door before you have a visitor, this might be an issue for your house.

DSC03472

You would think you’d go in the middle door in the back, well you don’t.  That would bring you to a tiny space leading to two tiny doors that will take you to the living spaces.  So you can pick from one of the many doors on the ‘L’ which will bring you right into the Kitchen or the Eating Area.

Greenbridge_2_32

As part of the renovation and addition, we created a clearly defined entry using  a pergola, lighting and sidelights on either side of the French door.  Construction by Becker Builders.

4. Door in name only. The front formal door is used at Halloween only. Reasons vary – maybe it can’t be seen easily, or it has no character, or other design problems making it uninviting, or common in new construction, there is no walkway leading to it!!

imagesCA44ULAM

I wouldn’t trick or treat here!

IMG_2831

We love projects like this – let’s get drawing!!

001

The rebuilt entry and porch have rich classical detailing, with inviting lighting, a generous landing with wide steps, AND a new walkway from the drive.  Construction by The Riverview Company.

Greenbridge_1_26s

This new entry in Georgetown, complete with new garden walls and paving (by UBLA design) was transformative.  Constructed by Meadowview Builders.

If your home has any of these ‘issues’, rest assured, you can make it better. The ideal entry is one where the landscape welcomes and brings you to a protected and well-detailed doorway, and on the interior has generous space and thoughtfully planned storage.  Feel free to contact me if you’d like some assistance with your design plans and estimates of associated costs.

Happy Spring!

Intrigued by Geothermal?

February 13, 2012

In my experience, geothermal systems are generally desired but widely misunderstood. Many of us understand that geothermal systems take advantage of the earth’s temperature to heat and cool buildings, that they involve deep drilling and that they are expensive to install, but cheaper to run that conventional heating and cooling equipment. Beyond that, general knowledge gets dicey.

This blog will give you an overview of geothermal systems, especially as they relate to residential applications. My description of geothermal systems is pulled from April’s Architect Magazine with additional input from Melanie Head at EnergySmart Alternatives. If after reading this, you are interested in geothermal for your own home, I would strongly suggest that you consult with a trained and experienced expert to find out more. My go-to local geothermal expert is EnergySmart Alternatives out of Wakefield, MA. Not only are they experienced installers and contractors, they have a team of engineers who make sure that every installation is done right.

Geothermal Systems – What Are They?

Geothermal systems for buildings, also known as geothermal heat pumps or ground-source heat pumps (GHPs), use the thermal energy stored in the upper portion of the Earth’s crust to heat or cool a building, replacing conventional heating and air-conditioning systems. “The temperature of the Earth down 20 or 30 feet is a relatively constant number year-round, somewhere between 50 and 60 degrees , says John Kelly, the COO of the Geothermal Exchange Organization, a nonprofit trade organization in Washington, D.C. “A geothermal heat pump moves heat to and from the Earth by circulating water through a well.”

In other words, in winter, a GHP moves the thermal energy from the earth into a building, and in summer it reverses that process, transferring heat from a building into the earth. These systems incorporate a piping loop buried in the ground through which anti-freeze is circulated, and the heat pump extracts the temperature from the anti-freeze and distributes it through the building, much in the same way that central air conditioning works. Alternatively, groundwater is directly circulated through a series of wells.

Either way, GHPs are significantly cheaper to operate than conventional heating and cooling systems. “The cost savings occur because the ground offers starting temperatures closer to what is desired for heating and cooling than the seasonal temperature extremes upon which many conventional air-source HVAC systems rely,” says John Rhyner, a senior project manager at P.W. Grosser Consulting in Bohemia, N.Y., a civil engineering firm that specializes in geothermal. “It takes less energy to make up that smaller difference in temperature,” Rhyner says.

diagram showing heat transfer to and from the Earth in Cooling and Heating Seasons

The three most common types of GHP systems are closed-loop, open-loop, and standing column well.

Open loop systems circulate anti-freeze through a sealed network of pipes buried underground. The anti-freeze within the pipes transfers heat from the earth to the building during the winter, and vice versa during the summer, by way of a heat exchanger. Since the anti-freeze flows in a closed loop, it does not exchange all of its temperature; it can get as warm as 80 to 90 degrees F in summer and as cold as 40 to 30 degrees F in winter. For this reason, the anti-freeze is usually a food-grade antifreeze with freeze protection between 15F to 20F (for example, ethanol) to keep the fluid from gelling during the winter months.

Closed-loop systems can be laid out either horizontally in fields, buried just beneath the frost line, or vertically in wells, bored typically 200 to 500 feet deep. Horizontal systems are generally used for smaller or residential projects with plenty of space. In geographic locations where there are few rocks and bedrock is not present close to the surface, horizontal loops are cheaper to install. However, horizontal loops are affected by outdoor air temperatures, meaning that they can become less efficient as a season progresses as the soil takes on the characteristics of the air temperature.Horizontal loop systems typically require large amounts of land. “For a closed-loop system, it’s all a function of how much pipe you can get in the ground with the open land area you have available to work with,” Rhyner says.

Vertically drilled closed-loop systems are more efficient than horizontal systems, as more of the pipe is in contact with a more constant earth temperature. They are most efficient if they can be drilled into groundwater rather than dry ground, since water is a good conductor of heat. “You get a certain number of tons per linear footage [a ton of heat is 12,000 British thermal units per hour], and can get more pipe in the ground going vertically than horizontally,” says Rhyner.

Standing column wells are another type of open-loop system that is well suited where bedrock is close to the ground surface. Standing column wells are typically less deep than vertical closed-loop systems with similar heat output capacity. Whereas vertical closed-loop borings are typically 250 to 400 feet deep, standing column wells can be anywhere from several hundred feet to over 2,000 feet deep. Steel casing is installed to hold the borehole open up to the depth of bedrock. The remaining depth is drilled through bedrock and is left as an open rock borehole. In these systems, the groundwater is pumped up from the bottom of the well, passed through the GHP, and then returned to the top of the well, where it filters slowly downward, exchanging heat with the surrounding bedrock.

Choosing which of these systems is right for a specific project requires calculating a building’s heating and cooling demand and conducting a subsurface analysis to determine the thermal capacity of the site, and how many wells or how large of a loop field will be needed. If the calculations are done correctly and the system is properly designed, GHPs can handle all of a building’s heating and cooling loads, no matter what climatic conditions prevail.

High Upfront cost versus Return on Investment

When designed and installed correctly, GHPs drastically reduce the amount of energy needed to heat and cool a building. According to the U.S. Environmental Protection Agency, GHPs are 48 percent more efficient than the best gas furnace and 75 percent more efficient than the best oil furnace. They require 25 to 50 percent less energy than other HVAC systems and bring down operation and maintenance costs by as much as 40 percent.

The main inhibitor to the wide-scale adoption of GHPs today is the relatively high up-front cost of installation. The main difference in cost between GHPs and conventional systems is the drilling cost. The mechanical equipment itself—the heat pumps and heat exchangers—is no more expensive than high-efficiency conventional heating and cooling systems. Annual savings on energy bills, however, offset the up-front cost. When taking advantage of the available incentives, payback periods for commercial GHP systems can be as little as 5 to 7 years when replacing an aging, inefficient HVAC system. GHP systems are especially cost-competitive against many conventional systems in new construction. In the past, GHPs were primarily popular with municipal and institutional clients, building owners who planned to inhabit and operate their facilities over the long term, and those who were simply more interested in environmental stewardship than the bottom line. With the currently available incentives and the high price of fossil fuels, payback periods have been significantly reduced making GHPs an attainable investment for more building owners.

The cost of installing a geothermal system can vary depending on site specifics. In existing buildings, challenges like duct routing, construction type, and space restrictions can affect the cost significantly. Such challenges are more easily overcome in new construction where these issues can be discussed with the architect or builder early in the design process. Your chosen geothermal company will be able to assist you with a cost analysis for the system that is best suited for your home. Their analysis will factor in the cost of installing a traditional heating and cooling system, the cost of fossil fuel and the available local and federal incentives. The following links have information on these incentives from both federal and local programs.

Local energy company incentives may also be available.

Common Myths About Geothermal

It’s surprising how often the same questions and comments arise regarding geothermal systems. The following, part of Energy Smart Alternatives’ ‘Geothermal Demystified’ series, sheds some light on some of these common misunderstandings regarding geothermal installations.

Myth #1: Backup Heating

There is a common misconception that GHPs are not able to provide 100 percent of heating requirements. This simply isn’t true. A properly designed GHP system will provide all of the heating and cooling requirements of the building. There is no need whatsoever to install a gas or oil boiler to provide a backup heat source.

 

Myth #2: Winter Installation

Transitioning from a fossil fuel heating system to a GHP in the winter can be a challenge. In most cases, the home will be without heat for one or two days while the new geothermal system is being installed. Although a temporary heat source can be used while the transition is being made, some homeowners choose to just add a few layers of clothing.

The drill rig used for vertical installations can drill through bedrock and certainly has the capacity to drill through frozen soil and ice. Trenching in winter can be difficult, though; the degree of difficulty depends on your geographic location and ground cover conditions.  When trenching in a small area, a few straw bails can keep the ground from freezing long enough to complete the installation. In some cases, excavators may not be willing to dig in the winter because of wear-and-tear on equipment.

Myth #3 Concerns about bedrock or ledge

Installing a vertical geothermal boring through bedrock is not a problem. Geothermal boreholes are created by cutting and grinding a 6-inch core through bedrock; there is no blasting, hammering, or pile driving. An experienced driller can drill between 200 and 300 feet through solid bedrock in one day. In New England, bedrock will usually be encountered within 50 feet of the ground surface and is encountered on almost every single geothermal installation.

Some homeowners have expressed concerns about drilling through bedrock in close proximity to their own, or their neighbors’, basement foundation wall. To my knowledge, no foundation damage has ever occurred – even when the borings were advanced within 10 to 15 feet of a foundation wall. The drilling will not cause an earthquake. It will not rattle the entire neighborhood.

Shallow bedrock can be an obstacle to horizontal closed-loop installations where hundreds of linear feet of trench are required. It can also be a problem when trenching between the location of vertical borings and the basement foundation wall. A careful evaluation of the site prior to digging will dictate the location of drilling or excavation so as to minimize encounters with ledge during excavation activities.

 

Myth #4 Concerns about wasting money on drilling.

EnergySmart’s team has installed over 200 tons of geothermal heating systems throughout New England and there has never been a situation where drilling has occurred and the installation has not been completed. First, it starts with an understanding of how the underground components of a geothermal systems actually work.

For both horizontal and vertical closed-loop systems, the heat transfer occurs between the soil or bedrock and the geothermal piping to the antifreeze circulating through the pipe. While groundwater improves the heat transfer properties of the underground portions of a closed-loop system, the presence of copious amounts of groundwater is not absolutely critical to the operation of the system. The presence or absence of groundwater should be accounted for in the design process but does not preclude the installation and effective operation of a GHP system.

Open-loop systems circulate groundwater through the GHP system.  It is imperative that the well has enough capacity to support the geothermal system.  Low well capacity can be overcome by fracking the well or deepening the well to increase its capacity and yield (this is a chemical-free fracking technique that is completely different from that used by the natural gas industry).  In extreme cases, systems that were originally intended to be open-loop can be converted to closed-loop when the well doesn’t produce sufficient good quality water. Similarly, if salt water or hard water is encountered, systems originally intended to be open-loop can be converted to closed-loop where water quality will have no impact.

Best of 2011

December 15, 2011

This year, through our partnership with The Riverview Company, we’ve had some fantastic opportunities to see our design work constructed in Wellesley, Stoneham, Newburyport, Amesbury, Sudbury and Copake, New York. Our project in Copake was by far the most challenging, exciting, and interesting. We thought a recap of the project might be of interest to you and hope you’ll agree.

Copake is about 3 hours away from us, around 2 hours away from most of our subcontractors – a logistical challenge. The clients are an amazing couple we’ve done several projects for at their Wellesley home.  This is their vacation home, so  they couldn’t be there to see day-to-day progress.  In order to take on the project,  they wanted the extra assurance gained from our relationship with them. There was never a question in Steven’s (my husband and co-owner of The Riverview Company) or my mind that we’d take this project on; we’d do anything for them.

Program and setting

The multi-acre property is on the outskirts of Copake, a town in the upstate New York Berkshires, on an expansive lake. Ed, the husband, fully aware of its problems, loves this getaway and its quiet and rural character. His wife Mary is of a more urban taste, but cares about the home because he does.

They knew that they wanted to make it look better!  Besides that, they also needed a new main entry and a screened porch with a fireplace and grill. New cabinetry and millwork would improve the interior, but they didn’t want to make major changes to wall locations. Other aspects of the project’s requirements included major upgrades to the insulation and mechanicals.

IMG_1940

Approach to house, view from street: the awkward entry door opens onto an undefined bedroom or den. It was unclear where to enter the house; the preferred entry was on the garage side. The windows have no trim and the exposed foundation is unattractive.

IMG_1948

View toward lake: lots of glass doors in the Living/Ding Room face the view, but the doors were failing. Other than those, one small window from the Kitchen and one from an upstairs bedroom faced the view.

IMG_3192

View from the Living Room to the Kitchen: the cathedral ceiling created some sharp, uncomfortable shapes.

IMG_3197

View toward the Stair: the large opening was unorganized and plain. The stair (behind the wall with the 3 frames) was narrow and closed.

IMG_3193

Kitchen: the owners wanted to keep the same layout, but upgrade appliances, finishes and add color.

The project

Working closely with the owners over the course of several months our plans took shape….

Copake plan

First floor plan: the dark lines show new construction and the tightly dashed lines indicate construction we removed.

The major plan changes were on the left side facing the garage and the rear, or water-side (top of page). The new Screened Porch makes the most of the expansive view and is designed to be a multi-use, multi-season room. In addition to the new Screened Porch, we added French doors from the Kitchen and a large bluestone patio accessible from the Living/Dining Room, the Kitchen and the new Screened Porch. On the garage side of the house, we added an inviting entry porch, with wide stairs accessing the front and rear yards and leading to an enlarged mudroom.

Riverview’s team of carpenters and subcontractors stayed at the house for many overnights during the work. Their continual positive attitudes and talents are what made the project a huge success.

071

On the interior, we rebuilt the stair and added an open rail to the stair and the balconies. In the large Living/Dining Room, we defined the spaces and ‘dressed them up’ by adding cabinetry and trim. The Dining Area cabinet is built for use as a buffet table and to store the owner’s plate collection.

065

The Screened Porch floor is bluestone and the fireplace wall is made with American Granite. In cooler months, a radiant floor and storm panels make this a 3-4 season room. This quickly became everyone’s favorite space.

076

We gave the Kitchen a facelift with a new countertop, appliances and window, and we painted the cabinets and walls. The new French doors open up the room to the lake view.

150

From the drive, the landscaping and new walk lead to an inviting covered entry porch. We added a stone veneer to the exposed foundation, replaced the siding and added trims.

136

The lakeside of the home and its outdoor spaces are open to the lake and the view.

Gratitude

For this project, we were fortunate to have incredibly committed and thoughtful clients and dedicated subcontractors. We want to thank The Riverview Company’s stellar carpenters, Stephen Tucker and Brett Belisle and their wives, the subcontractors: Kevin Thibodeau “The Plumber”, Pacewicz Electrical and Nelson Landscaping (stonework) and of course our fabulous clients, Ed and Mary.

A Camden Jewel

August 10, 2011

The Camden Public Library in Camden, Maine is a magnificent example of stately architectural and landscape design, and of the citizenry prioritizing the most important building in town. When visiting a few weekends ago, I was struck by the 1996 addition to the library, and how the architect, John Scholz, approached the design with a careful hand. The addition was built UNDER the existing library and grounds, with a new lower level entry at the side street.

From the library’s website:

“On March 23, 1896, the citizens of Camden voted to establish a free public library to be known as the Camden Public Library. The proud townspeople of Camden raised the money to build this library through various fundraising efforts. No assistance was provided by library philanthropist Andrew Carnegie. Mary Louise Curtis Bok donated the land for the library in 1916. Parker Morse Hooper and Boston architect Charles G. Loring offered building plans. The cornerstone was laid on August 17, 1927 and the Library opened its doors on June 11, 1928 with Miss Katherine W. Harding serving as the first librarian.

In 1996 the library underwent a great expansion under the south lawn. The opening of this Centennial Wing allowed the library to accommodate larger collections and computer-based technology without compromising the scenic or historic value of the original building.”

 

 

Most of our existing New England libraries are too small for current requirements and many of them could use an update and more space. There are a lot of examples of modern buildings being stuck on these old venerable structures, or even of libraries moving to new buildings on the outskirts of town, where parking and land is available. Because the addition was funded by the citizens and businesses of Camden, there were no federal or state mandates on parking, number of meeting rooms, etc. It was such a pleasure to see Camden’s solution, which demonstrates pride in the historic structure, and an optimism for the new.

A brief history of the library and adjacent grounds also from the Camden Library website:

“Constructed in 1928, The Camden Public Library, the only library in the village of Camden, Maine, sits at the highest point on Main Street. Architects Parker Morse Hooper and Charles Greely Loring chose to position their building close to the street, under the shade of existing elms and maples – a more direct relationship with its surrounding built environment rather than its larger landscape scenery.

The grounds of the Camden Public Library create a distinctly unique, highly articulated series of landscape experiences, the centerpiece of which is a public outdoor garden amphitheater. Designed by the renowned landscape architect Fletcher Steele, this landscape is one of his best works of art. It was designed and constructed between 1928 and 1931, and funded by local patron of the arts, Mary Louise Curtis Bok. Steele’s landscape design is an important transitional composition that blends elements of the traditional Neoclassical with the ‘new’ ideas of the French Moderne (Art Deco) and successfully marries the ideals of the Renaissance Italian garden theater with the richness of Maine’s native landscape. The popularity and unique qualities of the amphitheater immediately led to the christening of the site as the “Camden Amphitheatre”.

The library building is a long rectangular Colonial Revival structure whose primary axis runs southwest to northeast, parallel to Camden’s Main Street. From the rear of the library, the back door opens onto a secondary axis, linking the library to the Amphitheatre’s central lawn at an oblique angle. The primary axis for the Amphitheatre runs north to south, aligned with the primary views to the harbor. Experts have celebrated the use of this bent axis as one of the first steps in landscape architecture’s move from Classical Revival to French Moderne (Art Deco).

Across Atlantic Avenue, the two-acre Harbor Park, designed by the Olmsted Brothers between 1928 and 1935, continues and extends the views from the Amphitheatre toward the harbor and its busy waterfront. This park retains its own, aesthetically distinct design vocabulary, and remains a separate yet intimately connected, companion to the Amphitheatre. The park was designed in concert with the Amphitheatre, though its naturalistic design and informal planting program contrast significantly with the structured design of the Amphitheatre.

The Camden Amphitheatre retains its historic integrity, setting, original materials and the quality of original workmanship and design. Fieldstone, brick, grass and native trees and shrubs weave their way throughout the Amphitheatre, and wrought iron rails, light standards, gates and arches add grace and French-inspired Art Deco overtones to the carefully executed, highly detailed landscape design.

 

 

For more information, visit the library’s website, or the library itself! The Camden Library, Camden Harbor Park and Amphitheatre are located just off Route 1, on Atlantic Avenue, in downtown Camden.

Blogging about the Garbage Garage has connected us with amazing eco-enthusiasts around the world. Thank you for all the interest and comments.  This blog (the final on this project) will focus on the garage’s construction, the best part! See previous posts for information on Project Genesis and Design, Permitting and Preparation for Construction.

Construction Process:

The Long Way Home crew (Liz and Adam Howland, Erica Temple and Aaron Colvin) came from Guatemala to install the rammed-earth tire walls. Once permits were in hand, The Riverview Company coordinated the foundation work, including the rebar that anchored the foundation to the tire walls (and reassured the building inspector). I tried to prepare for the crew’s arrival by ordering the soil that would be used to fill the tires. My extensive research and questioning of experts was not helpful, and the soil ended up being far too sandy for the required use. Quote from Adam from Long Way Home “That’s not dirt.” Drat.

So, once the crew arrived, they had the cumbersome task of finding soil that would compact well in the tires. The selected soil ended up being a mix of sand and clay. At this point, the comparisons with construction in the US and Guatemala began. In Guatemala, there was is no special search for soil – they use what is there. Fortunately, we were able to use the sand later in the project as a base for the slab and the pavers.

Elizabeth (the owner) supplied the tires. The selection of the tires was crucial for this project since the finished exterior wall needed to be vertical and would have a stucco finish. We couldn’t have various thicknesses and widths of tires as can be used in the Guatemalan projects, where the final buildings are more organic and rough in finish. It turned out that there was some variance in the tires, but the LWH crew was expert at sorting and placing the tires accordingly.

As part of the permit approvals, we were required to have the compaction of the soil tested during construction.  The compaction consistently met and exceeded all requirements.  (More Guatemala comparisons…compaction testing?!)

The Riverview Company followed up with the installation of the slab, the wall, attic and roof framing above the tires, and the plywood underlayment and stucco exterior finish.  IMG_2794

Adam from the Long Way Home came back to install the glass bottles in the upper gable, and also installed some back-lighting behind the bottle wall to light the gable at night. The glass bottles were a challenge – we all love the idea of brightly colored bottles, but we had trouble finding bottles outside of clear, brown and green. There is a certain bright blue vodka bottle that we couldn’t get enough of…LWH did have a volunteer party, where everyone could get a chance to pound tires and to donate some bottles.  I gave tire-pounding a try that day, for about a minute.  Erica and Liz are now my new heroes.

A recap of the project:

The genesis of this project was my client, Elizabeth Rose, who is president of Long Way Home, a community-based, nonprofit organization in Guatemala that is building homes and schools using these construction methods.  In Guatemala, these construction types are a perfect solution for very poor residents who need shelter and community buildings.  In addition to the benefits noted above, building with tires, cans and bottles is cheap; the materials are virtually free, labor costs are low, and the building techniques are easily taught to otherwise unskilled laborers.

Elizabeth saw her family’s need for a garage as an opportunity to showcase alternative environmentally sustainable building practices and to help potential supporters understand the important work that Long Way Home is doing.

We are grateful to our amazing clients (Elizabeth and her husband Joe) for the opportunity to be involved in such an interesting and important project.  We appreciate their tenacity in getting the project done and their amazing outlook even during the biggest challenges we encountered.

Let us know if you have any questions about the Garbage Garage. We had such fun being a part of the project and hope that it will stand as a demonstration of creative approaches to construction that are sensitive to the needs of communities.

With best wishes,

Tires, Cans and Bottles, Oh My!

Tires, Cans and Bottles, Oh My! (Part 2)

It’s hard to believe that it’s been a year since we first started working on the “Garbage Garage” , a new garage constructed using rammed-earth tires and salvaged glass bottles. (see our post from June 2009)

Last month, the painters completed their work. It is done!

In this blog, I’ll discuss our design process and preparing for construction. Next month’s blog will be focused on the construction process.

Recap

The genesis of this project was my client, Elizabeth Rose, who is president of Long Way Home, a community-based, nonprofit organization in Guatemala that is building homes and schools using these construction methods.  In Guatemala, these construction types are a perfect solution for very poor residents who need shelter and community buildings.  In addition to the benefits noted above, building with tires, cans and bottles is cheap; the materials are virtually free, labor costs are low, and the building techniques are easily taught to otherwise unskilled laborers.

Construction Documentation and Planning for Construction

The project was quite a journey…we worked hard with Joe Fix, our structural engineer, on proper detailing for the project. The wall details and construction became a hybrid of the methods used by Long Way Home in Guatemala and methods traditional for this area and required for permit approval. Ericka Temple, who is part of Long Way Home, assisted with the construction drawings and was also part of the construction crew. The final design included a massive concrete foundation with steel reinforcing bars anchoring the foundation to the tire walls. Here is one of the wall details:

Placing the garage on the site was another challenge. Construction of the garage would be near a beautiful cherry tree and we needed to avoid harming it during construction. We also wanted the placement to ensure that the garage was not seen first while approaching on the drive. Matt Ulrich from UBLA provided the site design work for what proved to be a perfect location for the new garage.

We had some touch and go with the moving the project forward. Our first hurdle was finding a contractor comfortable working with the rammed-tire process. Our clients planned to bring a Long Way Home crew from Guatemala to complete the tire portion of the project, but contractors were still squeamish and bid the project (high) accordingly. We even had one low point in the project when our client requested that for cost reasons, we revise the drawings for conventional construction. The project lost all momentum until Elizabeth said, “Wait! What are we doing?” She really wanted the garage to be as originally conceived, a demonstration of construction using salvaged materials.

GreenBridge’s partner company, The Riverview Company, stepped up to the plate. Steven was excited to see the construction method and was comfortable working with the Long Way Home Crew. Next hurdle – permitting!

The Permit Process

When we were initially looking at the project, I spoke with the Georgetown building inspector. He was excited to work with us in the permitting process. He is also a ‘green’ builder, and we felt we had a strong advocate in the town. Once we were ready to submit for permit, we found out that he no longer worked there!! The interim inspector ended up being incredibly helpful and supportive of the project, but did request review from the state inspector and additional engineering documentation for the project.  Once we’d submitted proper engineering documentation and agreed to have the rammed earth in the tires tested for compaction throughout the construction process, the permit was approved. We obtained structural reports from EarthShip verifying the structural integrity of the rammed-earth tire walls, and we engaged McPhail and Associates to provide compaction testing.

With our soils engineer at the ready, contractor in place, and plane tickets purchased for the Long Way Home crew, we were ready for construction. Stay tuned to our next blog on construction of the Garbage Garage!

A Fable of Light

April 10, 2011

goldilocks Once upon a time there was a precocious little girl called Goldilocks who ventured into an inviting cabin nestled in the woods. She was so tired from her journey, she decided to have a rest. She wandered into the sunlit living room (too bright) and pulled across the curtains. Too dark! She pulled down the light-filtering shades. Ahhhh just right; she had a lovely rest.

When it was near evening, she woke and found that she was famished. So the bold but independent girl made her way to the kitchen to whip us something delightful for herself. She was cutting up some apples in the corner and needed more light, so she flipped the switch for the overhead fluorescent, happy in an ‘I’m green’ sort of way to see the familiar swirly bulb. PING! Out it blew, too dark again. Another switch brightened the countertops with beautiful LED under-cabinet lights. Oooooo, just right, perfect for preparing a steaming bowl of porridge topped by her chopped apples.

Then with her feast to the dining room, where the motion sensor spotted her and flipped on to a preset dimmed setting, leaving her surprisingly and for the first time, calmly satisfied with what she had…until in her silence she heard a growling sound in the distance just as the motion sensor lost her and the lights went out.

The moral of Goldilocks’ story is that lighting design is more than lumens and watts…it should also take into account our personalities and how we live in our spaces. High-quality and efficient lighting design includes a mixture of lighting choices and the use of controlled natural sunlight to the greatest extent possible. In recent months we’ve been researching lighting efficiency and current technologies for a kitchen renovation project. We can’t help but be influenced by our own prejudices, such as our big disappointment with the compact fluorescents we’ve installed in our own home’s light fixtures. We guiltily feel nostalgic for the ‘good old days’ when we didn’t think about our energy use every time we flipped a switch, and when our faces were always soft-lit by the old-standard incandescent.

We are also looking to January 2012, when the federal energy standard phasing out the incandescent will go into effect….one of our friends is hoarding them in anticipation of the phase-out. We are excited about the new technologies, especially by the great strides made in LED lighting and systems controls (dimmers, motion-sensors) over the past years.

We found some robust websites with loads of information about design strategies for efficiency, comparison of different light types (incandescent, fluorescent, LED, Halogen), and the new federal standards. California adopted the federal standard for efficiency in January of this year, and the State’s web site has some of the best information and links we came across. Energy Star is an especially useful resource since the standards are a reliable measure of a product’s effectiveness in a quickly changing and competitive market. All Energy Star fixtures are required to use at least 75% less energy than incandescents, and both CFLs (10x) and LEDs have far greater longevity (20x) than incandescents.

From our reliable standby The Green Building Advisor comes the practical advice, “The right combination of task and ambient lighting can save energy. A mix of lighting sources allows you to use the type of light you need: task lighting for reading, food preparation and other activities — where strong, concentrated light is helpful — or ambient lighting where more general illumination is better. Not all lights have to be on all the time, and natural light can be a significant contributor when floor plans are designed accordingly.”

Even with all the benefits of web research, we rely on our local experts. So we asked Lucy Dearborn at Lucia Lighting, what she recommends for efficiency and quality of light. She says one of her favorite combinations for ‘being green’ is to combine Eco-Friendly Halogen Lamps with the Lutron Eco-Minder dimmer. “You get fabulous bright white light when you need it and can dim down t a softer, warmer tone when you don’t need task lighting. The Eco Friendly light bulbs work with a regular dimmer, but we recommend an Eco-Dim Diva (perfect for The Divine Miss Goldilocks!). The Diva dimmer only allows light bulbs to go to 85% of their full capacity, so you can more than double lamp life and save energy at the same time! This solution is a great alternative to compact fluorescent light bulbs that sometimes don’t have a warm enough color & do not dim.”

The Eco Dim Diva (Lutron)         Color Kinetics LED under-cabinet light

For our kitchen project, we’re planning on a combination of Color Kinetics LED under-cabinet lights (as recommended by Lucia), some track and general lighting using dimmable Eco-Friendly Halogens, and big south-facing windows!

Our glimpse of Rome

November 17, 2010

My husband and I just got back from our trip to Rome – one of the strongest impressions we brought home is of the fabulous artisan shops dappled throughout the city.  While strolling in historic Rome, how wonderful to stumble upon a tiny shop where a man is tooling leather or another with a couple painting ceramic tiles.  Here is a sampling of some of the shops we happened upon on our trip…

These glimpses help us to remember what we love best about being in architecture and construction.  We have opportunities every day to select vendors, subcontractors, and consultants.  When we choose well, selecting those who are also devoted, diligent and who love their work, the process is rewarding and the projects are spectacular.

Arrivederci!
