Simple Genius

January 21st, 2014

It’s good to remember every now and again that problems can often be solved by simply stepping back and taking a fresh look at the big picture. A case in point: Deltec’s insulated headers.
Deltec uses R5 Thermal Shield as a wrap for insulating, and we have done so for many years. R5 Thermal Shield helps to achieve moisture management and energy efficiency, and is placed between the Typar storm wrap and plywood sheathing. R5 Thermal Shield boards are cut to size for each prefab Deltec energy wall panel and, inevitably, there is waste. Although R5 Thermal Shield is free of harmful chemicals, its disposal is regulated. This means it necessarily entered into Deltec’s waste recycling program for disposal.
Enter Steve Linton, (whom many of you know as Deltec’s president), who began working as our Green Building Coordinator in 2007. As a new employee, Steve wasn’t hindered by preconceptions as to how things had always been done. He looked at the R5 Thermal Shield. He looked at our double stud energy wall panels, with their layers of protection over almost 10-inch thick walls. He looked at the empty header ‘boxes’ (also 10 inches thick) at the top of each wall panel—and saw an opportunity: What if the excess R5 Thermal Shield were shredded and stuffed into the header, providing extra insulation for our homeowners’ wall panels? What if, at the same time, this resulted in the elimination of a product that previously had to be disposed of in a documented manner?
The idea was approved and the next step was to find an efficient way of shredding the board, a problem solved easily enough through the use of a chipper. Excess sheet metal was folded to form a rectangular-shaped funnel, which is placed over the header. The chipped R5 Thermal Shield is scooped up and into the funnel, after which the header is sealed. The result? An 8-ft wide double stud energy wall that boasts a solid header of energy efficiency.

A two-page spread from Deltec's award winning booklet.

Why do we work? For money? For fame, success, self realization or, perhaps, to change the world? Certainly, money enters into the equation somewhere—we all have to make a living. But a dream and a purpose are what lead the way to ambition. The people and companies who strive, excel and achieve do so for reasons other than money—it’s the desire to prove themselves, and hopefully make a difference, that pushes them.

Having said this, not all those who try, succeed. That’s where awards and public recognition come into play. Be they for individuals or businesses, awards acknowledge success as well as recognize the qualities that helped us to achieve it: creative thinking, ability, effort and, above all, excellence. Through awards we gain recognition from industry peers even as we showcase our company for the public.

Deltec Homes is proud to have won several national home building accolades in 2013. As part of the 2014 Jerry Rouleau Awards for Excellence in Marketing and Home Design from the National Association of Home Builders (NAHB), Deltec won both the Excellence in Marketing – Consumer Brochure Award, and the Home of Distinction: Excellence in Home Design, in the 3,001-4,000 square feet category for the Arnold House, a Healthy Built home in Montreat, NC.

Deltec was also one of five winners of the Marvin Integrity Red Diamond Achiever, an award recognizing and honoring impressive design, innovation, sustainability and quality in projects using Integrity products.

It’s not surprising that an inspiring company has inspiring leadership: Deltec Homes president Steve Linton was named one of Asheville’s ’40 Under Forty,’ an annual leadership award presented by the Biltmore Beacon. Honorees were judged on their business success and their achievements as an active member of the community. Steve is responsible for encoding environmental responsibility into Deltec’s core values and spearheaded the installation of 273 solar panels on the company’s roof, enabling us to power our officees and plant with 100 percent renewable energy. Most recently, he achieved his goal of capturing the national market share in net-zero home production by creating the Renew Collection, Deltec’s new line of high performance and net-zero homes. Also an active member in the community, Steve volunteers for Meals on Wheels and serves on the board of both the WNC Green Building Council and the Asheville Chamber of Commerce.

Brenda Cooke, responsible for communications and creative media at Deltec, won the 2013 Award of Distinction for furthering the mission of Deltec’s community partner, Wild South, by helping them reach out across the region through visually striking graphic design, as well as her involvement in organizing Deltec volunteers for various Wild South community events.

A commitment to excellence and innovation drives our company, from the president to admin, to sales and marketing personnel, and right on through to our building production staff. We are proud of our accomplishments.

A Deltec Dream Retirement Home

August 12th, 2013

Exterior and interior views of this Deltec home

In pursuing their dream of many years to downsize in retirement and have a one-of-a-kind place to call their own, Joe and Judy Baker, from Marietta, Ohio, turned to Deltec Homes, and could not be more pleased with their unusual home.

The Bakers chose a Deltec Windsor model on a basement. With 2,000 sq ft of finished home, it’s enough room for all their needs. The unfinished basement serves as a playroom for their grandchildren, and some storage.

One might think the unique shape might stand out sharply from neighboring homes, but thanks to the soft green exterior the Bakers chose, it blends in softly with the natural surroundings. In keeping with their unique home, Judy opted for unusual but complementary color choices transitioning from one room to the next.

A lot of thought went into planning the outdoor living area: The home has two eight-foot sections of screened porch and two open ones with idyllic views of the grassy area and trees behind the home. “We are very pleased with how it turned out,” said Judy Baker

Round: variations on a theme

August 5th, 2013

If you’re a fan of round homes, you’re probably well aware that there are several variations on the theme, from geodesic to domes, to monolithic domes to Deltec’s own panelized round. Real estate agent Jessica Clausen recently had cause to immerse herself in the subject, as she had clients who were interested in seeing round homes. Jessica condenses thousands of years of ’round’ history into one blog post as she explains how cultures from pre-history to modern times have constructed round dwellings using local materials. She also covers the aerodynamics and hurricane resistance of round homes, and why they are green.

Her succinct explanations of the various round homes, each with a photo example, makes for interesting reading in her blog post. Spoiler alert: Which round house do you think is her favorite? Deltec Homes, of course!

Jersey Strong in a Deltec Home

July 16th, 2013

When last we saw Deltec homeowners John and Kathy Guerin, it was 2010 and they had just finished building their dream home on the Jersey shore. Little did they know that not even two years later, their desire for a home that was “resistant to the winds coming off the Bay” would be put so severely to the test.

The Guerin's 'Jersey Strong' Deltec looks surreal in its perfection, in the midst of destroyed vegetation, bulkheads and damaged homes along Delaware Bay after Hurricane Sandy.

The 2,000-square-foot home is situated squarely on Delaware Bay, offering panoramic views of the water and wetlands. In anticipation of seasonal high water, the two-story house stands on pilings six feet off the ground. Unlike many homes along this beach, the Guerins, in defense of their ocean view and with complete trust in their Deltec, opted to skip erecting a bulkhead in front of their home. When Hurricane Sandy slammed the New Jersey coast last fall, the Guerins witnessed the true hurricane resistance of their Deltec: Although many nearby properties, even those ‘protected’ behind a bulhead, suffered significant water and wind destruction, the only damage to their home was a single turned-up shingle on the roof. Indeed, the bulkheads themselves were destroyed so as to be useless.

“The house withstood the storm very well,” said John Guerin to the press. “That’s one of the reasons we chose the Deltec design.”

Sandy was the second-costliest hurricane in U.S. history. With the forecasters expecting 2013 to be an above average hurricane season, you can bet many will be keeping their eyes on Deltec Homes.

When their Deltec dream home made the news in 2010, the Guerins had no idea that Hurricane Sandy would put the hurricane resistance of their home to the test.

R-Value? Don’t Forget About Air-Sealing

July 3rd, 2013

by Leigha Dickens

When we talk about an energy efficient building, everyone wants to know about the R-value. “R-value” is a measure of how well an insulating material slows the eventual loss of heat through the exterior surfaces of a building.

It is a fundamental law of thermodynamics that all of the heat that we contribute precious fossil fuels to put into a building will eventually leave it, for the same reason a cup of hot coffee left on a table at room temperature will eventually cool off. R-value is well and good—but it’s not the whole story, nor even the most important part of the story. Heat transfer comes in multiple forms, and one of the most important strategies for energy efficiency construction comes from paying attention to an entirely different method of heat loss, far too often overlooked in the construction industry.

Off-Grid and Grid Tied: It’s All Good

June 24th, 2013

Solar Panels on home

Many customers who consult with me on green building profess their dream of living in an off-grid home powered by solar energy.  Since solar technology is now widely available and cheaper than it has ever been, this dream is easier than ever for a homeowner to achieve.

However, solar is still a high-dollar line item on a construction budget or upgrade for an existing home, and whether the concept of an off-grid solar array makes sense for a particular home is a more complicated question.  There are multiple ways to set up a renewable energy system to power your home—with “off-grid” being only one possibility.

So What Does “Off-Grid” Mean?

“Off-grid” means you are on your own: there is no connection to the power company.  The only way to accomplish this in a setting where you want electricity even when the sun is not shining, is to incorporate batteries into your system.  Thus off-grid homes have no power poles running to them, and draw the power they need from deep cycle battery banks.

Grid-Tied: the Alternative

“Grid-tied,” by contrast, means that your house is connected to the grid, and you are still set up to buy your power from the power company when you need it.  But, when your solar array is producing power, you can either sell that power straight to the grid with the goal of financially offsetting the cost of the power you have purchased, or you use that power yourself first, and sell any extra to the grid.  You may not be using the actual electrons you have produced yourself, but you are still contributing green power to everyone’s benefit.

The Pros and Cons

The advantages of one system over the other come down to cost, comfort and independence. A grid-tied system will cost less because it does not require batteries, which form a significant portion of the cost of an off-grid system.  A grid-tied system for a net-zero home will also cost less because fewer solar panels are needed:  When you are not trying to store your own energy in batteries for later use, you do not need to produce quite as much energy in order to offset your yearly energy use.

A grid-tied system is also more flexible, both from a day-to-day use standpoint, and from a down-the-road standpoint.  Since you still buy any excess power from the grid, you won’t suddenly find yourself without electricity if you accidentally leave the lights on all night—although you will have to pay the electric bill for such a mistake.  And since you aren’t tied in to producing all of your own power yourself, you can use a grid-tied system to install as much solar as your budget allows, adding to it down the road as you are able.  Although you can add to an off-grid array down the road as well, if you don’t install enough to meet all of your power needs to begin with, you can’t wait on installing more capacity if you want to have enough power.

Pictured above is a grid-tied solar array installed on this round Deltec home in Virginia.  It produces enough energy to offset ½ of the home’s yearly energy needs, making the home a partial-net-zero home.  Installing the grid-tied array allowed the homeowners to put in as much solar as their budget allowed.

However, for safety reasons, grid-tied systems cannot function when grid power goes down (a live load on the line would present a danger to utility workers coming in to fix power outages), and to many independence-seeking homeowners, that is the biggest drawback of grid-tied systems.  There may be very practical reasons to go off-grid as well, such as a high cost of installing traditional power poles to a remote jobsite or a concern about local grid reliability.

Off-grid array installed by Leigha Dickens at Pisgah Astronomical Research Institute in North Carolina

Pictured, left, is an off-grid array installed by yours truly at Pisgah Astronomical Research Institute in North Carolina  The small research institute had a number of isolated telescope buildings on a high ridge that was prone to summer lightning storms.  Giving each building its own off-grid array made sense to keep this equipment powered even during frequent lightning-induced power outages at the site.

An off-grid system could also be argued to have a lesser environmental footprint than a grid-tied system.  For one thing, it forces you to adopt a more energy-conscious lifestyle, for every decision about electrical usage has consequences for how your system performs.  Additionally, an off-grid system produces its energy on the site where that energy will be used, eliminating the inefficiencies of distribution.  A grid-tied system is typically sized to offset the power consumed at the homesite, but is not often sized to offset the wasted energy from burning a fossil fuel at the power plant level and then distributing that energy.  An off-grid system represents a complete removal of your home from the environmental externalities associated with conventional power production—for some, this is by far the biggest attraction of renewable energy.

Pros and Cons Can Vary by State

How the state in which you live structures its rules and incentives for renewable energy makes a difference to which type of system makes more financial sense.  In general, grid-tied systems can have a dramatically shorter payback period than off-grid systems, as utility incentives for renewable energy or programs to pay homeowners for the power they produce typically speed up the time it takes to recover the up-front investment of solar.  However, in states that have very poorly structured rules for grid-connection, off-grid might be a better way to go solar while avoiding regulatory headaches.

I recently interviewed four Deltec homeowners who have built their homes with solar energy: two who chose to go off-grid, and two who chose to go grid-tied.  For some of these customers, state incentives played a role in their choice.  I compiled their stories into an off-grid fact sheet I use to educate our customers, which you can download from our website here.

A good place to go to start looking for the rules and incentives in your state is the North Carolina Solar Center’s Database of State Incentives for Renewables and Efficiency: http://www.dsireusa.org

If you’d like to start getting a handle on just how much solar you would need and how much it would cost, I have found several online calculators useful for arriving at ballpark figures:

Adawehi: A Healing Community

May 27th, 2013

Guest post by Claire O’Sullivan, Adawehi Community Member

In beautiful Western North Carolina, nestled in the Foothills of the Appalachian Mountains, is the Adawehi Wellness Center. The mission of Adawehi is to support healing and promote health on all levels—physical, emotional, mental and spiritual. When Jackie Woods, the founder, decided to construct the first building—the Healing Center—she chose a Deltec because it was well constructed, durable and a prefab kit that we as a community could assemble, with the support of Jackie’s contractor husband, Rodney Booth.

Adawehi community members build the 'Healing Center.'

Adawehi community members build the 'Healing Center,' a building envelope by Deltec Homes.

The center first opened up for business in June 1997. It provides space for services such as awareness classes, personal healing sessions, deep emotional-release massage, non-force chiropractic, color and sound therapy, astrology readings as well as nutritional counseling. A large room on the bottom level holds awareness classes, hosts 60 people for a community movie night and also hosts yoga classes. Finally, there is a space dedicated to the production of personal growth CD’s recorded by Jackie Woods.

The Deltec was built when most community members still lived in Atlanta, GA. We would drive up on the weekend, camp, or stay in nearby lodgings and then work all day to assemble the structure. This was the beginning of community life. Working together, eating together, sometimes freezing together!

The Healing Center, which is considered the heart of the community, wasn’t the only Deltec to go up on the property. Jackie’s personal home is also a Deltec, complete with a cozy wood burning stove, vaulted ceilings and amazing views. The Deltec architecture options allowed Jackie to create a space that reflects her love of nature, and cozy hominess.

The campus has two other Deltec homes where community members live, containing both private and shared areas. Deltec offers such diversity in floor plans that all four of the Deltecs on the property are completely different in design. The homes not only house community, but helped create community. Three of them were built by community members, volunteering their time on the weekends. The sides were delivered to a flat area where they were painted, and groups of people worked together to lift them and put the panels into place. We learned to support each other, work together, push ourselves and know our limits. We also learned to ask for help. The building of the Deltecs was a testament to what a group of people with a common vision could accomplish together.

Over the years the community has flourished, adding other buildings for community events, shops and additional healing services such as colon hydrotherapy and music therapy. Martial arts, drumming and tai chi classes in addition to a circuit training room have been added over the years. We also have a health food store, Beneficial Foods, and a Bed & Breakfast on the property.

Located on 125 acres of woodlands, the grounds are a haven for common and rare plant species. It is also a native plant preserve that includes walking trails lined with ferns, azaleas, and a variety of wildflowers and herbs, a beautiful place to experience nature’s healing & health.

You can find a complete listing of Adawehi events on our website, as well as a visit with one of our many healers or a lovely stay in the mountains at our B&B. We also provide Continuing Education courses for massage therapists and music therapists. For anyone seeking health or growth in any area of their life, we offer many products that will help. We invite you to visit our website if you can’t visit us in person!
