Going green doesn’t have to cost more. Experts at the NAHB Research Center have identified design and construction tactics that builders have used to minimize the cost premium for green.

Constructing a green home does come with some added costs, but a lot of builders find that green practices can actually reduce their construction costs and enhance the quality of the homes they build. Many green practices also result in operational and maintenance savings for homeowners.

Using a combination of input from builders participating in the National Green Building Certification Program and results from recent research we did for HUD on the costs and benefits of green affordable housing, the NAHB Research Center has identified seven beneficial practices to consider when building green for the affordable market.

1. Work closely with your suppliers

If you’re new to green building in general or to building green homes with a lower price point, you may want to start your journey by talking with your product suppliers.

Richmond, Va.-based First Richmond Associates has been building quality workforce housing for nearly two decades. Recently, the builder decided that going green with its homes would provide even greater value to customers and set its product apart from the competition. Susan Hadder, president of First Richmond, admits the company didn’t know much about green building, so she let her suppliers know about the new direction they were taking and asked for their help.

“A lot of them were as new to green as we were,” says Hadder, “but they were excited to help us find the best product options available from various manufacturers. It was kind of fun for everyone to discover something new.”

Hadder says she got very quick responses from all her product reps, along with some incentives, which helped her identify what the company needed to get its new green homes certified to the National Green Building Standard (ICC 700). She was pleasantly surprised to find that many of the green product options that would garner points for the home in the certification process were actually an even swap for her in terms of price.

Specifically with flooring options, she found that recycled-content carpet and padding, engineered hardwood flooring, and recycled tile for the bathrooms were all competitively priced with the products she traditionally used — some a few pennies more per unit, some a few pennies less. First Richmond now has two of their Earth-Friendly workforce homes (sales prices range from the $170,000’s to low $200,000’s) Green Certified to ICC 700 by the NAHB Research Center, and the company has plans for more.

2. Look for two-for-one green product benefits

To maximize green benefits while keeping construction costs low, use products or practices with multiple green features. For example, when specifying cabinets or cabinet materials, look for those that have low- or no-formaldehyde content and are made of recycled material. That way, you may be able to gain green certification points for both indoor environmental quality and resource efficiency. While most green rating systems won’t allow for “double dipping” on points (i.e., claiming points in more than one area for the same green attribute in the same product or practice), most will allow for multiple green attributes in the same product to be counted across multiple point categories.

3. Don’t forget about water efficiency

In our work with HUD, we found that water efficiency improvements for both new and renovated affordable projects are commonly overlooked even though they offer a quantifiable benefit to homeowners for little to no additional construction cost. Be sure not to discount the cost benefits for affordable clients of low-flow faucets, toilets, and showerheads, as well as rated water-saving appliances.

As for finding the products at an affordable price, there is a much wider array of low-flow toilets, faucets, and showerheads on the market today than even five years ago, and the most basic models are cost neutral with comparable non-low-flow fixtures. Most major plumbing product manufacturers now offer these products, eliminating the need for costly special orders, in most cases. With bathroom sink faucets, even if your manufacturer of choice doesn’t make a low-flow version, you can buy replacement aerators that satisfy the requirements of most national green rating systems for around $2 a piece.

4. Consider alternative framing techniques

Some changes in your framing materials or techniques might provide both cost/time savings and a means to an end in securing points toward green certification. For instance, consider using panels or trusses in lieu of site-built systems. These techniques are labor and resource efficient, resulting in less on-site waste and possibly lower labor and materials cost overall. Fabricated systems often create greater thermal efficiency over stick frames. Many green rating systems, including the National Green Building Standard, also award points for use of panels and trusses.

If you want to continue framing totally on site, there are several optimum value engineering (OVE) techniques that can save on material or labor costs, and can generate green points at the same time. Look into options like:

• Ladder blocking — uses less wood; provides more room for insulation; gets green points
• Two-stud corners — at least one less stud at each corner; allows for more fully insulated corner; gets green points
• Switch from 2x4s at 16 inches on center to 2x6s at 24 inches on center — may result in small increase in incremental cost initially, but gets a lot of green bang for your buck.

5. Explore low-cost strategies with design

Green, at any price point, is not accomplished through product selection alone. Many of the other “ingredients” for a green home involve strategies that can cost very little or nothing at all. For example, depending on the orientation and size of your lot, flipping a house plan is a very low-cost, low-effort activity that can result in green benefits like positioning the majority of windows on the south side of a home for passive solar and natural lighting gains.

6. Pay attention to placement and sizing of hvac and plumbing systems

Optimize your duct runs and centrally locate your mechanical room for material cost savings and increased energy efficiency. Even for smaller homes, be sure not to have more ducts or longer duct runs than you need in any part of the house. Using a central return also reduces material costs and is a simple system that can provide adequate circulation and cost savings to both you and your buyers.

Placing all your HVAC equipment, including ducts, in conditioned space within the home is also beneficial. In addition to creating significant energy savings for homeowners, this practice may also allow you to spec smaller, less-expensive HVAC equipment and limit or eliminate the need for additional insulation for the duct system. Many homes today, even those that may be otherwise energy and resource efficient, have oversized HVAC equipment. As the building envelope of your homes becomes tighter and more energy efficient, the HVAC burden is significantly reduced. A smaller system obviously costs less and could offset other green upgrades you’re making in your homes.

For your plumbing system, make sure you have chosen the most efficient design for your purposes. For multi-story homes, consider a stacked system, which will probably require shorter plumbing runs, less piping, and possibly less labor time from your plumbing contractor. Also consider centrally locating your water heater, as a central location makes the average of every run shorter, thereby reducing material costs.

7. Rely on green design professionals

Green homes often require a higher degree of precision in their design and construction to ensure that the finished product works the way it was designed to work, as a whole house relying on interdependent systems for its optimum efficiency and homeowner comfort. Having experts well versed in green products, practices, and protocols can save you thousands of dollars in trial-and-error and callbacks in the long run.

That being said, there are different ways to go about creating your design team. One way is to seek out experts in areas such as mechanical systems, plumbing design, and landscape architecture, with specific expertise in green building practices. Another tactic is to rally those with whom you already work to the pursuit of greener, more efficient homes. Similar to the enthusiasm and excitement Susan Hadder generated with her suppliers when First Richmond began seeking green solutions, you may generate the same kind of interest with your existing construction partners to learn all they can and contribute. Either way, it’s important to get everyone in your construction chain on the same page with what you’re trying to accomplish. Contractors and suppliers that are not informed can create inadvertent barriers to your ultimate success.

Green has been a buzzword in design for at least 25 years (I am going off of my Earth Day 1992 tote bag that was just unearthed from my parents home). What are some creative ways that you can use renewable materials in your home design?

Smart light bulbs, eco-mattresses, and a Tesla Powerwall that can run a 2 bedroom home on solar are some of the more obvious products available in the sustainable design market. For something less expected, you can also purchase a mushroom mycelium lamp that is painted with non-toxic paint that is grown instead of manufactured. Another unusual selection is

When designing your new construction or remodel, here are some easy choices to make your home a little more green and a little more sustainable with items that you already need:

Trex Decking: made from 95% recycled wood and plastic. This company also employs practices right in their manufacturing facility like eliminating the use of harmful chemicals and reclaiming factory waste.

Milk Paint: “green paint” refers to any paint that is an alternative to petroleum based paints. Milk Paint contains no VOC’s (volatile organic compounds) or additives that can be harmful to the environment. So you can breathe easy knowing that your walls, cabinets or outdoor spaces are working with you and the Earth.

Bio-glass backspash: recycled glass takes just 30% of the energy that would be required to produce it from raw materials. And there are stunning options to choose from!

LEED Certified Windows: these ensure energy efficiency is not compromised when embracing the views from your house.

Virtual Reality and 3D modeling: architect Michelle Kaufman has said “The most green material you can use is one that you never use.” With employing 3D modeling that allows you to go inside of your remodel or new construction, space planning is at a premium and every inch is accounted for. You can experience your home through VR and feel the space rather than just trusting or guessing what it the finished product will be like. Find a design team that will allow you to go inside your house and see your design selections well before purchasing or installation.

An environmentally friendly building product should cover three essential elements to make it green:

Where does it come from? – Is it a readily renewable resource? Is it local?

Does it have a high percentage of recycled content? How is it made? – What are the ingredients in the manufacturing process?

Is there fair trade involved? How much energy does it take to produce? How does it affect the environment after it is used? – Does the material off gas? What is its care and life span? Is it recyclable at the end of its initial use?

Caleb’s Journey Reclaimed Oak Floor

I live in Chelsea, which is built on a sea of clay. If I were to dig up the clay from my back yard, install it as a floor and polish it with beeswax from my friends at Berg en Dal Honey in Wakefield, I would probably qualify in having the greenest floor. Leaving aside such pure and perfect ambitions, let’s consider more realistic possibilities for the average consumer choices:

Bamboo

Often thought of (and definitely marketed as) the greenest floor on the market, bamboo has probably the longest list of pros and cons. In order for bamboo to meet high environmental standards there are a number of hurdles to consider/overcome.

Bamboo grows incredibly fast, takes very little energy to cultivate, and makes for a very hard floor, around 14-17% harder than maple. If produced and harvested properly the farming of bamboo has a very low environmental impact. To achieve this, the bamboo must be harvested no earlier than every 7 years and cut 6 to 12 inches from the ground, so that the plant can grow back without replanting. The problems are that wild bamboo is used and a lot of the farmed bamboo is harvested at three years, making for a lower quality product.

The manufacturing process also needs to be evaluated. The raw bamboo is stripped, steamed, baked, and dried. It is then compressed using glues and is usually prefinished. Ideally the glues and finishes used are non-toxic with a low VOC content and manufactured in an ISO certified facility. Unfortunately, too often this is not the case; very few of these glues and finishes have a low VOC content and most of the work is done in ramshackle factories with no concern for the health and safety of workers. I have seen pictures of buildings in the deep forests where the workers are wearing nothing but shorts and making their own glues in a large toxic vat over a fire. (This is the $.99/sq. ft bamboo sold at Uncle Joe’s Flooring emporium.)

Bamboo floors take a lot of energy to manufacture and, as it all comes from China, a considerable amount of embedded energy to transport.

Wood

Ah wood, the classic and still most popular choice. Some say you can’t do much better than a locally produced farmed wood product in a solid format (low energy) with a natural oil and wax finish. In Ontario and Quebec you can now find FSC certified solid maple flooring at a fairly reasonable cost.

The opposite end of the spectrum is imported clear-cut Merbau covered in a heavy coating of toxic off gassing Varathane. The devastation of the Merbau forests prompted Greenpeace to produce a hefty volume dedicated to documenting the destruction of the forests. The scary fact is there are many species of endangered trees readily available at your local flooring store.

Engineered wood flooring is manufactured by bonding a veneer of solid wood on top of two to three layers of other, less valuable products. In the greenest examples these secondary layers are made of recycled or waste materials. This manufacturing method results in a more efficient use of the best / most valued wood, stretching out the resource use while still satisfying the consumer need for an abundant variety of options.

Reclaimed wood – On the outset this seems to be the ultimate in environmental choice. There are two main types of reclaimed wood:

1. Flooring made from wood reclaimed from barns or old farmhouses, planed down and reinstalled for your walking pleasure. Unfortunately, due to the intense labour involved in reclaiming the wood, and the limited supply of the product, it is an expensive option. Reclaimed wood also generally needs to be finished onsite, which is a general pitfall for most consumers.
2. River Run Reclaimed flooring is manufactured from logs dredged from the bottom of rivers. It’s a great concept to create quality flooring and it is generally less expensive than reclaimed barn board. The argument against this practice is that no one is quite sure of the long-term impact of pulling up the silt and possible toxins from rivers such as the Ottawa and the Fraser. Impact studies will take some time to finish to before we can really know the environmental consequences.

Cork

I’ll be honest; I have a personal preference for cork. It is warm, soft, and beautiful. The tree is harvested every seven years by shaving the bark from the trunk, not by cutting the whole tree down. Cork flooring is made from the scraps of the manufacturing of wine corks. (In turn, pin boards and gaskets are made from the scraps of making the floors.) Cork trees are highly prized and protected in Spain and Portugal. But as with Bamboo, on the flip side cork flooring is an engineered product from abroad. What’s worse, currently a large portion of cork is shipped to China for manufacturing and then hauled back to Europe and North America for sale. On top of the embedded energy debate, one needs to make sure that the cork is manufactured using low VOC glues and finishes.

Carpet

Carpet is not very fashionable at this time, being looked down upon as a cheap, short-term product that over time will provide a breeding ground for mold and bacteria as the toxic chemical protection wears off. But there is a bright green future in carpet, especially in commercial applications. Up and coming companies are using recycled and recyclable content. (If you haven’t seen “The Corporation”, Interface Carpet’s Ray Anderson is a truly inspirational businessman-come-environmentalist.) Kraus is manufacturing such a product in Ontario.

There are also similar pros and cons for Linoleum, ceramic tile, and cement, but I am running out of room.

In the end, making a decision on the most environmentally friendly floor will involve a lot of tomato, tomato, potato, potato; it can come down to personal priorities. Regardless of your choice there are always trade offs.

If you are really stuck…. I have an acre of clay, send me an e-mail.

Home automation is something that many people are implementing into their home designs due to the fact that it makes the home more convenient and functional. However, there’s an added benefit to home automation: reducing your environmental footprint.

Source: Freshome

So how exactly is home automation a green building feature? Well, one of the features that home automation can provide is the ability to integrate smart lighting controls that allow you to turn off all your lights at once with the touch of a button, as well as power controllers that will turn off appliances automatically. This makes using electricity much more efficient and helps to ensure that you’re not wasting energy.

Another excellent home automation feature is the occupancy sensor. We’ve all forgotten to turn off the lights when leaving the house at one point or another. By installing an occupancy sensor, you’ll ensure that your lights don’t just stay on until you return. This is because an occupancy sensor can detect if no one is at home and will automatically turn off your lights in an empty house.

Consider home automation as part of your green building design and contact us at Trilogy Builds for more green building techniques.

Singapore is known for many things from their vibrant food culture to their rich multi-cultural heritage to their high-tech industry. To add to their list, Singapore is leading the way in Asia in terms of green building.

This shouldn’t surprise anyone since Singapore Island only covers 85 square miles and is one of the most highly urbanized areas on Earth. This level of urbanization creates many special ecological and economic problems which Singapore is dealing with via green building technology.

Buildings in Singapore use a wide variety of methods to go green. These range from advanced solar paneling, landscaping the buildings themselves, using better types of recycled/sustainable building materials, as well as improved ‘smart lighting’ which works in tandem with available natural light.

The Singapore government has promoted this move towards green building with a generous incentive plan which has led to 1,534 new buildings passing the local equivalent of LEEDs certification. Along with older retrofitted properties, green structures account for 1/5 of all Singapore buildings making them Asia’s most green country.

LEED homes have come a long way in recent years as a number of significant changes have been made. The trends in green home design have seen a lot of progress, transforming into what you see before you today. What are these changes though, and how can they best benefit you?

• The great thing about LEED homes is that they are far more realistic in their goals, whilst allowing you to achieve your ideal vision.

• Sustainable treatments are the main methods used during their construction, meaning that they’re more innovative, as well as cheaper too.

• A quality LEED home will contribute to its surrounding environment as they each give something back. This could be either a rural landscape, or even the architecture of an urban setting.

• LEED homes should be set in the style of their surroundings.

There’s plenty more progress expected from within this particular area of green home design. For more information, or for any other enquiries, then get in contact with an expert today to see how they can help you.

Green buildings refer to buildings built to reduce their impact on the environment. Common examples include buildings with superior insulation, buildings built using sustainable building materials, and buildings filled with efficient features.

According to the U.S. Green Building Council, 4.3 million Americans either live or work in a building that has received its Leadership in Energy and Environmental Design. At present, an impressive 44 percent of commercial and institutional buildings under construction in the United States have received the same, which is predicted to rise to about 50 percent by 2016.

The U.S. Green Building Council believes that this increase is happening because more and more people are realizing that green building practices help them save on costs. Furthermore, as interest continues to grow, the government is beginning to recognize the benefits to the national economy. As a result, the trend is predicted to strengthen in the near future as government support increases.

Prospective homeowners and other Colorado residents interested in learning more about green home design should contact Trilogy Builds to speak to one of our representatives.

Trilogy Partners is always busy continuing to learn more about new developments in green home design. Our continued efforts benefit our customers with new ideas that can be incorporated into the energy saving design of their new home.

Recent lessons we have learned lessons from the three finalists of the From the Ground Up green home competition in Syracuse. These affordable green homes have taught us much about incorporating some exciting features that will drastically increase energy efficiency from the ground up during the building process.

By adhering to principles of Passive House as the From the Ground Up finalists did, we realize the importance of incorporating passive energy savings elements. These features include south facing windows and increased air tightness through higher R-values in insulation and framing design. Being these features were subjected to the harsh winters in Syracuse, this makes them extremely suited for green house design in our Colorado Mountain area.

There are always more lessons to learn when it comes to saving energy through design and Trilogy will continue to study the latest innovations for the benefit of their clients.

Smart home buyers are recognizing the advantages of incorporating materials made of recycled plastics into their newly built Trilogy Homes. Keeping with the trend for green home design, the amount of products that are available is now larger than ever before and the possibilities are endless because of the versatility of the material.

Recycled plastics can be used to produce eco-friendly building materials made of HDPE (high-density polyethylene) or PVC (polyvinyl chloride), such as decking, exterior trim and flooring. You will enjoy the advantages of having a sturdy, well-made product that is naturally resistant to rot and mold growth unlike other materials.

Textiles for the home that are created from PET (polyethylene terephthalate) plastics, such as those used for water bottles are now available in different forms. Fibers created from PET are similar to nylon in their durability and offer protection from moisture and stains, while resisting fading. This makes this material a good choice for carpeting and upholstery for your furniture that will continue to last.

Less energy and pollution are involved in the production of recycled products, which is good for the environment. This latest trend in green home design offers several benefits, in addition to reducing landfill waste.

Sustainable design has become popular among high-end architects for good reason. Eco-friendly furniture is good for the environment and also your health in the long run. Furniture designed with sustainable materials preserves forests by repurposing materials. Sustainable furniture design also avoids toxic chemicals used in most furniture today. Here are a few of our favorite furniture pieces from a new face in sustainable design.

New York-based designer Michael Robbins creates one of a kind handmade sustainable furniture from reclaimed wood. He got his start in New Mexico while building stools and chairs for his adobe home. Each piece of  furniture is handcrafted from his work studio, an old barn in the Hudson Valley. Robbins focuses on the art of form and simplicity in his design. His collection is quite new, and was just released in 2012.

Though Robbins designs and crafts each piece of furniture himself, every piece has its own unique feel. Some dark wood, some light wood, others are blends of dark and light or even painted neon green. More recently, he has added tables and lighting to his portfolio. Robbins take a classic twist on traditional furniture, by giving it the look and feel of abstract art.
