Escape from New York

Sandra Barty created her very own quiet, cozy space in the Southwest

By Bethany Conway, The Las Cruces Bulletin

It is not hard to see why those coming from the big city find Talavera so tranquil. For Sandra Barty of New York, choosing to locate her winter residence in Las Cruces was one of the easiest decisions she ever made.

Custom Home

Her life in the City of the Crosses began behind “A” Mountain at 5022 Black Quartz Road, a home that she purchased along with friend Laurie Churchill.

“In 2004, I visited Las Cruces and I fell in love with the sunsets and the views and the house, which was built by Jim Graham,” she said.

Since the 1970s, Graham, owner of Sun & Earth Inc., has been a pioneer when it comes to resource conservation and energy- efficient design and is known for his implementation of both active and passive solar. When it came time for Barty to build digs of her own, she could think of no one better to take on the task.

“I knew that Jim Graham was the only builder I would ever work with,” Barty said. “He is a man of such incredible integrity, and he really cares. He cares about the environment, he cares about his clients and he cares about the houses he builds. Jim is a gem.”

For her dream home, Barty chose a lot just down the street at 5012 Black Quartz Road, which did pose a challenge.

“This lot looked ridiculous,” Graham recalled standing outside of the home. “We dug it back into this hill. Most people want to build on the top of a hill – it seems like the real natural thing to do – but it doesn’t make a good environment for people because it is usually very windy. This lot is a lot calmer.”

After choosing the location, Barty set to work planning her dream home with the help of architectural drafter Naida Zucker.

“One of the things that Jim said to me when we were first designing the home in November of 2004 was to go through books of Southwest architecture and indicate the things that I liked and the things that I didn’t like. From that, I knew that I wanted a traditional adobe structure with one big room in the center and several rooms branching off to the sides,” she said. “I loved the simplicity of it, but I wanted it to have elegance.”

With the help of designer Maureen Villmer, Barty achieved her goal for grace. What came to fruition when Barty, Graham, Villmer and Zucker combined their creativity was a two-bedroom, inviting adobe with many energy-efficient characteristics.

“It has a feeling of spaciousness, but at the same time it is very intimate,” Barty said.

Though the home has more windows than Graham is accustomed to and veers from his normal passive-solar design, Barty, like any resident of Talavera, just couldn’t help it.

“We situated the house so we would take maximum advantage of the views of the mountains and the valley,” she said.

Leaving some of the adobe walls un-plastered, they gave the home a rustic appearance.

“The guys went over every single line of mortar in that exposed adobe to make it smooth and even,” Barty said. “Jim is a meticulous builder, so he made the details as good as they could possibly be.”

Not only did the adobe walls turn out aesthetically pleasing, but they also make for an energy-efficient, sustainable structure.

“The adobe walls provide a place to store heat in the winter time,” Graham said. “There is also insulation on the exterior, so that keeps the home from losing heat.”

Using solar reflectors over the skylights on the roof, Graham also created a way for Barty to harness the sun’s energy.

“Between of the adobe walls, the way the house is situated and those solar collectors, I had almost no propane bill for the winter,” Barty said.

Photovoltaic panels, which Barty added later, also help to lower her bills during the summer time.

“Right now, even with my air conditioner on all the time, El Paso Electric is still sending me payments of about $90 a month,” she said.

Though onlookers are happy to hear of its many energy-efficient features, the home’s style speaks for itself. Cherry wood floors as well as custom colors and tile work are found throughout.

“Maureen helped me pick out those cherry floors. It is as though they have a personality that makes the house incredibly warm,” Barty said.

If the cherry wood floors have a personality, then the kitchen’s heavy concrete countertop has its own persona.

“I saw that in a New York showroom,” Barty said. “It has a softness to it.”

“We actually made it upside down,” Graham added. “You turn it over and you polish and you wax it. It is really a lot of work. It was more work to do this than to build the house.”

If you ask Barty what her favorite feature is, the answer is easy. Located on the north side of the house is a studio like no other. Made to function as its own suite, it includes a 17-foot window, a huge dance floor, a recessed seating area and full bathroom.

“I wanted to have space for a music concert or a free movement or yoga or anything like that,” she said. “I love that (seating) area for meditation because it really gives you the feeling that you are in the earth.”

Barty hopes it will offer the next resident a place to let their creative juices flow.

I knew that Jim Graham was the only builder I would ever work with.

Jim Graham overcomes the hype of going green

Sun & Earth lays the building blocks of energy efficiency

By Jonathan Butz, The Las Cruces Bulletin

Everyone seems to be endorsing “green” lately because of rising temperatures, higher energy costs and the endless mantra that seems to ring in every corner of our lives – green, green, green.

Despite the instant recognition people feel when they hear the word, not every product marketed as “green” is what it appears to be.

Sun & Earth Construction President Jim Graham hopes to clarify the current phenomenon of “green-sploitation” by providing realistic service in sustainable, energy-efficient building and remodeling.

Since the 1970s, Graham has been on the forefront of green building in southern New Mexico, making sure that clients get exactly what they expect from sustainable living.

“We’re cautious of green washing, which means applying a ‘green’ label on something just so you can sell it,” Graham said.

Although green building has changed dramatically since the 1970s, Graham said he is still intent on building houses that adhere to Sun & Earth’s strict criteria of aesthetics, accessibility, energy efficiency, ease of maintenance, durabil-ity, safety and comfort. Specializing in energy-efficient air conditioning, solar water heating and sustainable roof coating, Sun & Earth Inc. strives to create a service and product that is more than just a buzzword.

Passive solar

“Green building has become more sophisticated since the ’70s and focuses not only on the sustainability of the house, but on aesthetics and livability,” Graham said. “At one time, green building was pretty raw. It may have been efficient, but it wasn’t comfortable to live in or pleasing to look at.”

Things have changed now, and more people are becoming interested in green building, Graham said. With more affordable options available, long-term utility savings and a number of tax credits and incentives, Graham said it is becoming easier for indivduals with modest incomes to have their homes remodeled or built to green standards. He said he remembers a time when he only saw a response from those associated with universities and research; however, he has seen his clientele base broaden, primarily among retirees.

“Affordability is a mainstay of what I do. If I do something more expensive than the mainstream it’s usually due to nicer amenities,” Graham said.

“I tailor to the clients’ individual needs and I try to be realistic about what I can do for people.”

With a lifetime’s worth of construction experience and a biology degree from New Mexico State University, Graham continues to challenge himself, creating innovative residences for people of southern New Mexico.

“I’ve always set a goal of making buildings 80 to 90 percent more efficient than conventional buildings,” Graham said. “When conventional buildings get more efficient, it challenges me to build more efficient buildings.”

Graham said one of his recent successes has been a two-stage evaporative cooling system, which he calls “one of the best available in the area.”

Additionally, Sun & Earth offers roof coating that can reduce the amount of needed air conditioning, and ezinc solar water heaters that can shave dollars off utility costs.

Now, after years of service, Graham said he always has the future in mind. He hopes to contribute to a cleaner, safer and more beautiful future, despite what color it may be.

“A building is not sustainable if people aren’t going to want to look at it 100 years from now,” Graham said with a laugh.

Inside the ‘Platinum Trailblazer’

Don and Beatriz Rudisill reach for the highest level of LEED certification

By Bethany Conway, The Las Cruces Bulletin

Editor’s note: This is the first article in a series following the construction of Las Cruces’ first Leadership in Energy and Environmental Design (LEED) Platinum Certified home. Though owners Don and Beatriz Rudisill will not know whether they achieve this certification until their home is complete, sharing their story will help others on their journey to becoming green.

For Don Rudisill, the story behind his home at 4367 Isleta Court is in many ways similar to that of “the first penguin.”

Reaching for Leadership in Energy and Environmental Design (LEED) Platinum Certification – never before achieved in southern New Mexico – he is a lot like the first penguin that takes the plunge into cold, unfamiliar territory.

Green Home

“When you watch a film about penguins, most people notice how they bunch up on the edge of the ice. No penguin wants to be the first to jump into the water where unknown dangers may lurk,” Rudisill said, referencing an excerpt from “The Last Lecture” by Randy Pausch. “The same happens with building something new. Many people like the idea of a green home – improved energy efficiency, a healthier home and improved utilization of the planet’s resources all sound good – but there are many unknowns.”

After two years of intense planning and overcoming many obstacles, Rudisill is blazing a trail for others to follow – a green trail. He will accomplish this with the help of builder Jim Graham of Sun and Earth, who has 30 years of green-building experience.

“It a very ambitious project,” said Miles Dyson, owner of Inspection Connection LC and the only certified Home Energy Rater in Las Cruces. “He has it very well laid out.”

Dyson, southern New Mexico’s go-to guy when it comes to achieving LEED and Build Green New Mexico (BGNM) certification, will inspect the home throughout the entire process. Credit categories for LEED homes include Sustainable Sights, Locations and Linkages, Indoor Environmental Quality, Water Efficiency, Materials and Resources, Awareness and Education and Energy and Atmosphere.

The trail began when Don and Beatriz Rudisill sat down to create the home’s footprint. The unusual floor plan is partially the result of the couple trying to meet the LEED requirements for passive-solar design. According to the LEED program, the maximum conditioned square footage for a three-bedroom house should be 1,900 square feet. By going above this amount, the couple loses points. By going below it, they gain points.

“We are trying to stay under 1,690 square feet, which gives us three points (toward LEED Platinum Certification),” he said. By creating a storage closet for seasonal clothing near the master bedroom and a sunroom on the southeast side of the house – two areas that will not be heated or air-conditioned – they will be able to add extra space not counted toward their conditioned square footage.

“This is going to generate a lot of solar heat in the winter,” Rudisill said of the sunroom. “During the summer months, we intend just to leave the windows open, and this will be a bonus room. Jim (Graham) is going to put a fan in here, because in the winter it will produce surplus heat that we will be able to blow into the house.” Solar hot water panels hidden behind the parapet over the garge roof will provide additional heat.

Another way they were able to gain points and energy efficiency was by keeping all of the hot water within a 20 foot radius. For this reason, the kitchen and bathrooms are all “clustered within the center of the house.”

“If you look at the plans, we had this 20-foot circle drawn, and that created another requirement for the floor plan,” Rudisill said.

When it came to the slab itself, they used 30 percent fly ash – a waste product from coal after it has been burned in a boiler.

Next on the list was the framing, which was done using finger-jointed lumber. “You take scraps that are too small to be used and make a usable piece out of it,” Rudisill said.

When it came to placing the Marvin windows with ULTREX fiberglass frames, Rudisill also had to be very particular in order to gain LEED points. “I put a lot of time into trying to capture the views because we are given glass budgets. You have to keep the glass within a certain percentage,” he said.

One of the most important attributes of the home are the Structured Insulated Panels manufactured by KC Panels of Animas, N.M, which will make up its 4-inch thick walls. Graham said this is the first time he has used the insulated panels. The thermal resistance, or R-value of the panels, is so high they perform almost twice as well as standard 6-inch walls and result in more than 30 square feet of space being shifted from the walls to the available living space. They are held together by polyurethane foam.

“The foam creates a complete seal around the building,” Rudisill said. “So again, through using this one product, we are saving space and improving energy efficiency. The air-tight seal contributes to improved indoor-air quality, and the foam has a class-one fire rating, improving the safety of the home.”

From 10 a.m. to 1 p.m. Saturday, April 18, and 1 to 4 p.m. Sunday, April 19, during the Guild of the Las Cruces Symphony Association’s green home tour, titled The Greening of Las Cruces, residents of Las Cruces will get a chance to visit the construction site and view these panels up close.

“I have an interest in trying to get the information out there about what really goes into a well-built house,” said Rudisill, adding that by educating the public he is actually gaining more points toward the home’s certification.

Though the Rudisills are hopeful they will reach their goal, they won’t know if LEED Platinum Certification will be achieved until the project is complete.

“Being the first to attempt the Platinum level means that we have to be the first in the area to earn certain points. One of the areas that we are earning points is by working as an integrated design team. We have been working very hard as a team with Miles, Jim and several subcontractors all putting their heads together to help ensure that the rating is achieved.”

Assuming they achieve the platinum rating, the Rudisills will receive $9.50 per square foot in tax credits – close to $15,000.

Sustainability

Why should we do anything about sustainability?

The answer in all cases is to insure a decent, secure, healthy life for all species on this planet.

As consumers, we are frequently confronted with lifestyle decisions that can impact our environment.

There are choices in this life that can make a big difference in what the quality of life will be for those who follow us.

Going with the flow of our culture is hard to avoid, and unfortunately the flow is not in the right direction for evolving a sustainable future.

One of the most momentous choices that any of us will make is the kind of house we live in.

A sustainable building can be defined as any building that is sited, designed, constructed, operated, and maintained for the health and well-being of the occupants, while minimizing impact on the environment.

Sustainable building practices offer an opportunity to create environmentally sound and resource-efficient buildings by using an integrated approach to design. Sustainable buildings promote resource conservation by including design features, such as: energy efficiency, use of renewable energy, and encouragement of water conservation.

By promoting resource conservation, sustainable building design creates healthy and comfortable environments, reduces operation and maintenance costs, considers environmental impacts of building construction and retrofit, and concentrates on waste minimization.

Sustainable building design also addresses such issues as historical preservation and access to public transportation and other community infrastructure systems. The entire life cycle of the building and its components is considered, as well as economic concerns, environmental impact and over-all performance.

Using Fly Ash to Improve Concrete Quality and Reduce Environmental Impact

Sustainable Construction For A New Millennia

This article is about using fly ash to improve the quality of concrete while reducing its environmental impact. We are all concerned about the quality of Portland cement concrete used in our projects, and I hope also about reducing the environmental impacts of our built environment. There is a way to achieve both of these at the same time by the addition of fly ash to concrete.

Fly ash is a byproduct of the emission controls of coal fired power plants. Most fly ash is landfilled but can be recycled as an ingredient of concrete. It consists basically of tiny spheres of silica and is considered a “pozzolan” additive. Pozzolans are essentially inert fillers that take the place of much more reactive Portland cement and have been used since the Romans learned to make extremely durable concrete 2,000 years ago, even in aggressive marine environments. Portland cement production uses lots of energy and produces massive amounts of carbon dioxide.

Typically Fly Ash is used to replace 10-60% of the Portland cement in concrete. The effect on the concrete is to reduce shrinkage and reduce heat from the hydration of the more active Portland cement. It can lead to a much more durable concrete with less cracking and increased resistance to adverse reactions including Alkali Silica, chloride, and sulfates. It is widely used in highway construction, pre-casting plants, and dam construction. It is less widely used by residential concrete contractors, primarily as a minor hot weather additive to retard setting and reduce cracking, however it can be used in higher amounts and in cooler weather. The key to its successful use is by controlling the water/cement ratio, as are so many other aspects of good concrete.

There is often considerable resistance to fly ash use by trade contractors and even concrete producers. Let’s face it, construction is often very conservative about adopting “new” practices and there is a learning curve to fly ash adoption.

The most common concerns about using Fly Ash is that it will slow concrete setting time and will reduce high early strengths. These can both be addressed with water reducing additives. We can classify water reducers as standard or super plasticizers. Essentially their purpose is to make concrete more workable while using less water. Concrete use is often a conflict between more workability, which make the subs life easier, and a lower water to cement ratio, which does good things for the concrete and makes the engineer happy. Plasticizers can make everyone happier. So how do we use them, how much do they cost, and what is this about a learning curve?

Standard plasticizer is often included with regular concrete mixes, is added during batching at the plant, and shouldn’t have much effect on the cost. Superplasticizer can be added either at the batch plant or at the jobsite, is usually used at 40-90 0unces per yard, and might cost $.10/ounce. This incremental cost increase should be offset by the substituting of inexpensive fly ash for more expensive Portland cement.

Superplasticizer can be thought of as dehydrated water and is useful for other places in residential construction such as making concrete countertops and Portland based tile grouts on floors.

I would recommend learning to use superplasticizer in smaller projects at the jobsite such as sidewalks or driveway sections, before doing a large slab or foundation. The most challenging aspect of its use is probably timing. When used at the batch plant it may lose its effect by the time the concrete is placed. When added at the site it may delay setting time unacceptably. Avoid the temptation to add more water if it sets too soon and instead add more superplasticizer, which is a reason to keep some on the job, even when most of it is added at the plant. If setting is delayed it may be that the plant is adding too much water to improve mix ability and should add “super” early on. Properly used fly ash with super makes for a more workable concrete with higher early and ultimate strengths and improved pump-ability. Since fly ash is a recycled product it can be used to achieve points in LEED rating.

Hopefully this article on fly ash use in concrete will help you make better concrete while reducing its environmental impact.
