Green is the New Gray and that's Okay!

My journey in sustainability continues with today’s report on a seminar attended during the JLCLive show in Providence, RI. Sponsored by The Journal of Light Construction, a Hanley Wood publication, JLCLive caters to residential and light commercial builders through print, web and trade events.

The mission was participation in a full-day seminar on green building to broaden my knowledge, bring clarity to thoughts on sustainable construction, and depart with fewer questions than when arriving.

The time spent was well worth it. A good show for any remodelers or builders interested in refreshing their library of knowledge, seeing new materials and tools, or simply connecting and exchanging notes with others in the market.

Before describing the seminar it’s important to recognize those who often go unrecognized. While delving into sustainability I’ve found people are eager help and I have many to thank.

How Did I Get Here?

Due in large part to our hyper-connected world I learned of the Journal of Light Construction and JLCLive through word-of-mouth, better yet, by word-of-tweet.

Those who know me are aware that I use Twitter for its unique ability to easily find and connect people with shared interests. One such person is Leah Thayer, a talented editor with Remodeling Magazine (Hanley Wood) who tweets regularly posing great questions, and promoting dialogue. I’m grateful to Leah for introducing me to a blogger at Remodeling Magazine named Michael Anschel. Michael is principal of otogawa-anschel a design + build firm from Minneapolis and a knowledgeable opinion leader of the sustainability movement. An interesting mix of design talent, community responsibility, entrepreneurism and unbridled enthusiasm on all things green. By that, I mean green with a pragmatic twist. Michael also happens to be the speaker for the green build session at JLCLive.

Unrelated to JLCLive are more to acknowledge, more than I can practically highlight in this post. Three individuals stand out. Sean with SLSConstruction offers a background in remodeling and residential construction with a small business vantage point on sustainability. Another friend to mention is Merrill Stewart, LEED AP and founder of the Stewart Perry Company a commercial contractor with nationwide scope and leader in the transition to better building. And James Bedell, a bundle of energy and expert in commercial lighting design by day. The remainder of his time is consumed organizing Build2Sustain with focus on sustainable reuse of the many existing commercial structures across the US. I’m convinced he doesn’t sleep and will leave the world a better place than how he found it.

All engaging, all leading, all going well out of their way to help me wade through and learn about green building. None of whom I would know without Twitter. Follow them.

A Square Peg in a Rectangular Hole with Radiused Corners

I almost fit in...sort of...with a little extra effort and finishing I may just make it through. These were my feelings as I arrived for the seminar. The room was cavernous as you might expect with a convention center. Chairs carefully aligned in rows, three to each narrow folding-table, knee-breaking undercarriage, structured learning. Rigid.

I strolled in behind the presenter (suit was a dead giveaway) as he casually suggested that we ditch the lecture style rows and rearrange the furniture in semicircle format to encourage dialogue. Relieved. No need to sit with my back to contributors or speak to the rear of anyone’s head. Many others wandered in and all set-to, grabbing chairs, sliding tables, shaking hands and just getting the job done-predisposed to action.

Attendees chose seats and got comfortable anticipating the start, with hushed conversations among table partners and noticeable fidgeting. Michael broke the ice asking each student to rise, provide background on themselves, names, where they were from, how long they’d been in business, that sort of thing. Most were from the Northeast with one participant from Washington State and midwest representation from our facilitator. The diversity in origin proved beneficial in highlighting some of the regional differences in design and construction. The crowd was generally upbeat, all either remodelers or new construction general contractors. I was the square peg, the sole product guy in the room, and pleased to be there.

The attendees viewed sustainability as a paradigm shift, wanting to understand more about it, hoping to sort through the relevance and priority of various green debates - eagerly planning to grow their businesses, do well for their clients, and by extension leave positive affect on society. This was different and welcomed.

After introductions Michael set expectations by saying, “I won’t be giving any answers today, the session will be interactive and we will challenge ourselves to think through issues and solutions.” That’s exactly what we received...lesson learned.

My Quest for the Elusive Formula

Before attending the JLCLive event I reviewed materials furnished by the USGBC, NAHB, MNGreenStar, BuildingSciences Corporation, EnergyStar, NC HealthyBuilt Homes and many others. Each source providing its own brand of sustainability or regurgitation of work adapted from others. Given the volume of information available and varying explanations of sustainable construction this session confirmed that a formulaic approach to understanding may not be the best approach-getting it right is more complex than that, and rightly so. My mission to come away with “the formula” was dashed but edification wasn’t.

We held helpful discussions, tangential deep dives on specifics, covered basics and organized thoughts and approaches to participating in green. The primary takeaway for me was high-level ordering. A mental process to use in understanding cause and effect with design and material selection related to home design and construction. In the interest of full disclosure the following principles align best with the MNGreenStar school, of which Michael Anschel has affiliation...for this class the prioritization was slightly different and I found it helpful.

  1. Site/Community Impact - extension of the projects affect on local and global community.
  2. Water Conservation - consideration for use of potable and gray water both in and near the project.
  3. Indoor Environmental Quality - establishment of a healthier indoor environment through mold reduction, minimization of toxic inhalants, efficient and natural lighting.
  4. Resource Efficiency - durable materials, minimal waste, infrequent maintenance.
  5. Energy Efficiency - build for efficiency, reduce green house gas emissions and permanently minimize energy expense.
  6. Adaptability - homes are built to stand the test of time, adaptability is a critical success factor and often overlooked.
While all green-build programs have merit and strive toward sustainability I found this list easy to absorb and, specifically, the priority attached to each item compelling. These are just a few highlights from the discussion and I hope a good starting point for readers of this blog who venture this way.

Have I learned? From the JLCLive session and from other information reviewed I now default to questions before drawing conclusions. I see buildings and wonder about optimal orientation. I pass hardscapes and consider permeability and heat island effect. I see wall assemblies and think insulation and vapor management. I notice irrigation and consider gray water with native and adapted plants. Building materials move me past function and aesthetics to embodied energy, end-of-life, life-cycle. Roof lines now do more than keep weather out, they’re about geometry, color and energy management. Learning.

The Dawn of Progress

As important as the material shared in the session, I found refreshing the enthusiasm of those participating. These were construction pros. Some more accomplished and comfortable with the notion of green build than others but each offering valuable insights for this square peg. One group stood out in both attendance numbers and zeal for doing things better - for continuous improvement. Harmony Builders, led by Wyatt and Dan, formed their model around sustainable building, not for fashion or trend sense, but because it was the right way for them to add value for their customers and to lay a foundation for generations to come. Long-term thinkers - doers - role models - winners, leaving satisfied customers and durable projects in their wake.

The Harmony Builders team knew a great deal about green building through experience, were happy to share and most assertive at learning more and better tips, techniques and ideas. In Dan’s words “Our process for building is constantly being scrutinized and evaluated by us. One of the things we say to each other is that when you stop learning you start going backward. I find it sad when I meet a builder that knows it all and has for a while.  Like Michael Anschel said, ‘there are no answers.’  I believe It is the struggle for the answers that make the difference.”

Dan’s comment sums up my experience with the green build session at JLCLive nicely. Do things better.

I left with more questions than when I arrived, adapted mission accomplished.

Green is the new gray and that’s okay!

Coincidence...or Convergence?

Did you notice the recent announcement from Google about edging into the Internet Service Provider (ISP) space? This is earth-shattering stuff...viewed alongside other recent announcements from the tech world an interesting image of our near future emerges.

With this experiment, Google is giving incumbent ISP’s like AT&T, Qwest, Comcast, Cox and others a significant nudge in the direction of better, faster, richer, open internet service provision. A broadband notion that has been hotly debated but otherwise constipated for decades.

What This Could Mean For Us

The Google experiment targets between 50,000 and 500,000 people in the US with internet speeds of 1,000 Mbps (1Gigabit per second - 1Gbps)...roughly 100 times faster than most internet subscribers receive today...promising a reasonable price. From the announcement, Google divulges three key elements to their initiative. In their words:

  • Next generation apps: Google wants to see what developers and users can do with ultra high-speeds, whether it's creating new bandwidth-intensive "killer apps" and services, or other uses we can't yet imagine.
  • New deployment techniques: They will test new ways to build fiber networks, and to help inform and support deployments elsewhere, they will share key lessons learned with the world.
  • Openness and choice: They will operate an "open access" network, giving users the choice of multiple service providers.

This is really powerful stuff...it places the traditional incumbent ISP business model of slow cable plant deployment with glacial and expensive ratcheting up of internet speeds  in peril. Google’s stance will certainly turn heads and cause sleepless nights for those milking the US customer base for cash while the rest of the globe surges ahead in the bandwidth race.

Google mentions several “killer apps” in their blog including the ability to transfer full length BluRay movie files in under five minutes...enabled by 1 Gbps transfer speeds. Astonishingly fast relative to current DSL and Cable Modem ISP rates.

If we look at what else is happening in the world of technology the story becomes more interesting.

Enabling Technologies

A recent post, “Light Peak and You”, discussed Intel and their activity with emerging  “Light Peak” optical technology. Intel is making fundamental changes to optical circuitry that promise orders of magnitude cost reduction compared to similar telecommunications grade devices.


Why is this a big deal?

Well, you may not recall when USB crept into every computer and peripheral...we hardly noticed it...but all now use USB and benefit as a result. “Light Peak” has the potential to do the same but with orders of magnitude performance enhancement and far greater physical reach. A game changer.

These advancements enable extremely fast data transfer between devices with greater distances (300 feet) than the latest in USB, version 3.0. The new chips are tiny with projected costs low enough to make sense in consumer electronics.

Remarkable performance. The Intel products will enter the market with speeds of 10Gbps and scale to 100Gbps within ten years. Targeting spaces within the home or office, that’s ten to one-hundred times faster than the transmission rates predicted by Google for long haul applications. Comparing these speeds with that of Google’s ISP plan suggests file transfer of the same BluRay sized files in seconds...not minutes.

What isn’t obvious is that the optical fiber Google relies upon for the long haul (intercity and directly to the home )applications is capable of similar speeds...by simply adding high speed transmitting/receiving equipment at the ends of the links. Therefore it’s conceivable to have similar speed on the Google network feeding incredibly rich content, on demand, across great distances, anywhere. Consumer choice.

Connecting the dots

Rumor mills are rife with suggestions that both Sony and Apple are courting Intel and the soon-to-be-released “Light Peak” chips...suggesting that their consumer electronics will soon offer staggering performance.

Lots to think about...lots going on in the world of technology. Some questions to mull over:

  • Is it a coincidence that 3D-HD (larger files than traditional BluRay) was all the rage at the recent Consumer Electronics Show? A technically savvy way to solve digital rights management hurdles and an astounding development for consumers to bring into the home.
  • How rapid is global data growth? The Data Deluge: Economist.com
    • How about Apple’s new iPad...a neat little handheld computer with a killer high resolution screen...what would it take to add a new “Light Peak” chip inside?
    • Would adding new chips to the Apple line of iMac and other desktop computers with cinema quality monitors be too difficult?
    • Sony? Well, they know a thing or two about high definition television...3D-HD production...and distribution of content.

    There are certainly more examples to raise...more dots to connect...but the same conclusion remains. In the end it comes down to an accelerating need for more bandwidth...bigger, faster pipes to carry rapidly expanding volumes of information...in the long-haul...and within the home.

    Google’s project gets at removing a recognized bottleneck in the long-haul networks and encourages traditional players to accelerate their efforts. Once improved, the bottleneck itself will shift from outside to inside the home or building. It seems Intel is preparing for this with “Light Peak” and I suspect their direct customers (consumer electronics suppliers) will quickly follow suit. Ultimately, this means wiring upgrades within the home for applications we can’t even envision today. Evolution.

    Part 3: Staggering, Remarkable, Stupendous!

    Well, admittedly, it’s not cold fusion, perpetual motion, or antigravity...but this experiment has been worthwhile for the kids and also for Homepath Products.  We’re pleased with results and they confirm our beliefs.

    The experiment we’re running with the help of the kids delivered some interesting information...and an opportunity to learn more with further study.

    For background on this project see the earlier posts, Part 1 and Part 2. The investigation answers an important customer question about how eXapath affects the energy conserving qualities of insulated walls.


    Specifically - ”If that thing (eXapath) is in my wall displacing some insulation, what affect does it have on energy conservation?”

    As described in the earlier posts, our test chamber sits outdoors and was designed to create a large temperature gradient between the warmth contained and the cooler outside air. Using a fully insulated cube (Demilec SEALECTION™ Agribalance sprayfoam insulation provided by USInsulation) with an incandescent light bulb as a heat source, we installed the eXapath™ in-wall cable pathway system within one wall and minimized air infiltration with commonly available firestopping caulk and putty. Doing so emulates a typical home installation (see photo), allowing us to determine the affect the eXapath system has on a fully insulated exterior wall.

    Once the chamber was built and checked to ensure that everything worked properly, we set it outside, allowed it to stabilize, and began to examine how the system reacted with direct exposure to the cold New England weather. Given that insulation serves only to slow down the process of heat transfer we knew that all surfaces would allow some level of heat energy to escape. We predicted that the various materials making up the walls would generate unique surface temperature profiles and the experiment sets out to demonstrate that. To determine the differences we devised a method for logging the surface temperature for three distinct locations on the walls for comparison to the outside air temperature:

    • Intersection of eXapath, insulation and outer sheathing
    • Intersection of insulation and sheathing
    • Intersection of 2 x 6” stud and sheathing

    For temperature readings we scanned (6:00 AM, 2:00 PM, 10:00 PM) the target areas daily on the outside surface of the chamber using a Ryobi Tek4 Professional Infrared (IR) Thermometer. The data was tabulated in a spreadsheet and compared to the internal and external air temperature as shown in the chart below.

    Through the first four weeks of testing (tests ongoing) the internal temperature fluctuated between 75.3 and 102.5 ℉. The blue line on the chart shows the internal temperature.

    During the same period the outside air temperature ranged from a low of 6.0 ℉ to a high of 53.9 ℉. The 100 Watt incandescent light bulb allowed us to drive a consistent level of energy into the test chamber and served to convert that electricity to heat. Consistent heat generation allowed the chamber itself to react to the external temperature...isolating insulation performance to the outside air temperature only. The large difference between the internal and external temperatures provided the strong temperature gradient necessary to force heat transfer to occur between the warm interior and the cool exterior.

    The Bottom Line

    As anticipated, all surface temperatures remained near to but slightly higher than the outside air temperature. It is hard to discern because the readings were all very close, but the lower line on the chart displays:
    • Outside air temperature
    • Surface temperature where eXapath, insulation, and sheathing intersect
    • Surface temperature where insulation and sheathing intersect
    • Surface temperature where 2 x 6” stud and sheathing intersect
    The bottom lines, literally, show that the section of wall where the insulation displacing eXapath system is installed performs as well as sections of wall completely filled with insulation. This confirms the hypothesis that installing the eXapath system in the exterior walls of a sprayfoam insulated structure is not detrimental to the energy conservation of the structure itself. Slight variation was shown by each material but temperature profiles of each construction material combination were very close...almost indistinguishable graphically.


    A Closer Look at the Data

    To assess the relative performance of the various building material combinations we sorted the data table by outside temperature in descending order. Doing so helped to reveal the performance trends more clearly. After that, we compared the variance between the external temperature and the various building material combinations...this step amplified the reported results revealing a bit more about how each material fared relative to the others under test. In essence, the outside temperature records become a reference line (zero) and the temperature difference for all other materials is plotted against the external temperature to highlight performance differences.


    The main finding with the second chart is that temperature variance, compared to external air temperature, falls largely above the blue reference line...slightly higher temperature than the outside air. This is what we expected to see given the large temperature gradient between inside and outside the chamber. In cases where the surface temperatures fell below the blue reference line there is a strong correlation to rising outside temperatures....in these instances we believe the temperature changes of the construction materials lagged behind the more rapidly rising outside air temperature.

    The interesting point, and the primary purpose for running this test, is that the eXapath system shows no real performance degradation despite displacing some of the insulation within the wall.

    Questions Remain

    It should be noted that IR thermometers offer an accuracy of ± 1.5% compared to the actual reading. In addition, the operating range for the thermometer itself ranges from 30 to 122℉. While making measurements, care was taken to keep the temperature of the IR thermometer within the operating range recommended by the manufacturer to maximize accuracy.

    The Experiment Continues


    To confirm the trends revealed in the experiment and support the findings of the IR thermometer we are extending the experiment to verify our findings.

    While having an energy audit performed at our site we asked Chris Rhodes of Right Angle Home Inspections, a Building Analyst certified by The Building Performance Institute (BPI) and certified Level 1 Thermographer, to use her FLIR B-360 Infrared Thermography Camera to evaluate the test chamber. Our hope was to create visual identification of thermal bridging occurring through the test wall of the chamber in order to show differences between building material combinations,

    The photo to the right is an infrared image of the test chamber that reveals "hot spots" or areas where heat energy is leaking out of the chamber. For clarity we've labeled the positions where the eXapath system is installed, where only insulation exists, and where a 2 x 6" stud intersects with the outer plywood sheathing. This image confirms our findings.

    The three small purple patches indicate the position of digital temperature sensors we've added for phase 2 of the experiment. In phase 2 we hope to generate more detailed information to gain a more precise understanding of the differences between each building material combination.
      So the experiment continues...after our "furnace" burned out the kids and I peeled caulk from around the cover seam and removed the heavy lid...it provided the curious sensation of opening a sarcophagus. We added a new 100 Watt light bulb, replaced and resealed the cover, and are ready for phase 2 readings.

      Please check back with us for more updates soon.

      Part 2: Kids Don't Suffer Self Imposed Limits - We Can Learn From Them

      This is part 2 of a series addressing the great questions customers ask.

      As mentioned in an earlier post, we view this investigation as a unique way to bring science out of the classroom and into the real world. A way to engage the creative minds of our kids in a practical exercise that reinforces what they are learning in school while we answer a question that our customers have.

      Whoa! Did You Say Hollow?

      ”If that thing is in my wall displacing some insulation, what affect does it have on energy conservation?”

      The short answer is that the eXapath in-wall cable pathway system does not present a problem with energy conservation...but it’s a complex question that deserves thorough investigation and a complete response. Getting to that answer is, well, a science project in heat transfer, an adventure into the second law of thermodynamics.

      Our Investigation

      We assembled the gang, discussed the main question, and then probed more deeply, encouraging the kids to think of approaches to investigating the affect of the eXapath system on energy conservation.

      The kids learned about home design and construction. We discussed framing, sheathing and all the stuff hidden in walls. Namely - insulation, drywall, vapor barriers, siding, wiring, pipes, vents, etc. We then discussed various heating systems  and how insulation helps slow down the process of heat transfer from warm to cold...inside to outside during the cold winter months. To make it official I uttered “the second law of thermodynamics” one time only, noticed the kids eyes rolling, and reverted to energy conservation and the importance of efficiency in homes.

      Much of the discussion revolved around insulation and how it takes advantage of the thermal properties of air to slow down heat transfer. We showed the kids several types of insulation including fiberglass batting, cellulose, and a relatively new form called sprayfoam. For our project we selected sprayfoam for its unique ability, when applied, to find its way into all cracks and voids that might otherwise allow air infiltration. The foam cures in minutes while trapping air and offers high R value (resistance to heat transfer). For this experiment we needed to emulate insulation in a full scale home so we contacted local insulation experts for advice.

      Air that is moving or circulating is ineffective as insulation but “trapped”, “still”, or “dead” air offers good insulation. A key goal in construction and weatherization is to minimize air exchange or infiltration. With eXapath, the preferred installation includes firestopping caulk where the system penetrates the shoe or plate of a wall. In addition, the exposed eXapath pipe is blocked with a cap or pliable firestopping putty.  An unintended benefit of firestopping is the creation of a closed system containing still air...a good insulator.

      How Good is Good?

      To answer the question of how the eXapath system affects an insulated wall we needed a way to control some variables and isolate the effect of the eXapath system. We turned to the kids for their ideas and were enlightened by their grasp of the complex variables involved...they truly see no limits.

      The kids envisioned building an estate tricked-out with geothermal HVAC, solar photovoltaic electricity, wind power, abnormally thick walls to hold more insulation, a heated pool, horses, lots of horses...and a piranha infested moat.

      I did my best to explain that their ideas were terrific but slightly beyond the scope of our plan and budget. After negotiating a bit we settled for an insulated 5 foot cube with 2 x 6” walls, floor and cover. For a heat source we opted out of geothermal and chose a top-of-the-line 100 Watt incandescent light bulb powered by mundane but readily available AC electricity. The idea is to create a strong thermal gradient between the warm internal temperature and the cooler outside air. We anticipated that the “system” would constantly fight to reach equilibrium as outside temperatures fluctuated and that by checking the temperature along the wall precisely where the eXapath was installed we would learn more about the affect of eXapath on energy conservation. In addition, using traditional framing, we could collect additional data from a wall section backed by only insulation and where a 2 x 6” stud met the sheathing. Doing so should allow us to compare traditional construction methods with those using the modern eXapath system.

      Building the Chamber

      All walls, floor and cover are modular and built by Bogaert Construction using 2x6” framing materials with 1/2” CDX sheathing. Local experts from USInsulation filled the modular wall cavities with 5 1/2 inches of Demilec Sealection Agrilbalance®, a 3/4 pound semi-rigid sprayfoam.
      The six components (walls, floor, cover) were then assembled by the Homepath Products team, kids included.
      We added the light bulb and installed an internal temperature sensor. After giving the system a dry-run to test the heat source and internal temperature sensor we sealed all internal joints with Great Stuff™. To minimize convection we added HILTI CP-618 firestopping putty to plug the exposed pipe of the eXapath system and then sealed all external seams with silicone caulking.

      What We Expect to Find

      For data collection and to allow meaningful comparison we plan to use a number of temperature sensors. One is housed inside the chamber to keep tabs on the internal temp and to verify that the heat source is still functioning. We also plan to monitor the outside air temperature. Ideally, the skin of the chamber should equal that of the outside air temperature, indicating that the insulation is 100% effective in conserving energy. The second law of thermodynamics tells us that heat transfer can never be stopped, only slowed down.

      Therefore we expect readings from the skin of the chamber to be slightly higher than the outside air temperature. This will confirm that some heat is escaping through the materials within the walls. For external readings we plan to use an Infrared (IR) thermometer to monitor target markings for the wall section where eXapath, insulation only, and a 2 x 6” stud are located. The chamber itself is oriented so that the target wall faces north away from direct exposure to sunlight...this minimizes solar radiation as a variable in raising the skin temperature.

      After the initial shakedown we moved the chamber outside into the cold New England elements and allowed it to stabilize for forty-eight hours. Once stablized we began logging temperature readings.

      The testing is underway, please check part 3 of this series for interim results.

      Part 1: Customers Ask Great Questions

      Thoughts on jobs, kids, innovation, entrepreneurship...and our approach to economic recovery.


      While writing this post I stumbled across a New York Times article written by Op-ed Columnist Thomas L. Friedman entitled “More (Steve) Jobs, Jobs, Jobs”. The piece resonated, inspiring me to take a short detour and disclose a bit more about what we’re up to at Homepath Products.

      Friedman discussed federal policy-making concerning job creation through innovation. Paraphrasing, he suggests that the current administration should bolster job creation by stimulating our youth through creativity, innovation and entrepreneurship. “What the country needs most now is not more government stimulus, but more stimulation. We need to get millions of American kids, not just the geniuses, excited about innovation and entrepreneurship again. We need to make 2010 what Obama should have made 2009: the year of innovation, the year of making our pie bigger, the year of ‘Start-Up America.’”

      Friedman continues “to reignite his youth movement, he [President Obama] should make sure every American kid knows about two programs that he has already endorsed: The first is National Lab Day. Introduced last November by a coalition of educators and science and engineering associations, Lab Day aims to inspire a wave of future innovators, by pairing veteran scientists and engineers with students in grades K-12 to inspire thousands of hands-on science projects around the country...The president should also vow to bring the Network for Teaching Entrepreneurship, or NFTE, to every low-income neighborhood in America. NFTE works with middle- and high-school teachers to help them teach entrepreneurship. The centerpiece of its program is a national contest for startups with 24,000 kids participating. Each student has to invent a product or service, write up a business plan and then do it.”
       

      In general I agree with Friedman. More innovation begets opportunity for success; more success stimulates innovation, in turn, growing the pie and fueling economic expansion. He presents some well conceived ideas echoing an industrial era economist named Joseph Schumpeter who espoused “creative destruction” and focused on the importance of entrepreneurs to strong economies. Friedman adds a noteworthy twist...that is to nourish the innovation and entrepreneurship process through exposure during youth.  I find this compelling and believe it may help sidestep the tendency toward risk aversion that sets in with age. This notion parallels what we’re doing in our own small way here at Homepath Products.

      For many reasons I traded in the security of corporate America to pursue this new venture called Homepath Products. One (of many) important goals was to spend more time with family. For years I noticed opportunities slipping away while I focused on career, a universal dilemma faced by all parents and those with aging forebears...a challenge with few good answers...part of life.

      At Homepath Products we innovate, we experiment, we teach, we are a startup and our kids play a vital role in what we do and, perhaps more importantly, why we do it.

      Reflecting on Friedman’s assertion that youth should be energized to nurture creativity and become entrepreneurial consider the following. Our kids also need opportunity to grasp the interconnected nature of things and events, to learn risk taking, and to become aware that they have a voice in matters seemingly beyond their sphere of influence...beneficial lessons for adulthood.

      Many regular readers of this blog know that Homepath Products recently introduced the eXapath™ in-wall cable pathway system. With this innovation we aim to improve how homes are designed and built, complementing energy conservation while preparing the structure itself to change as consumer electronics evolve. Not an easy task when wires within walls compete for the same space as insulation.

      To see where kids come into the picture you must first understand the product.

      Energy Conservation and Upgradeability

      One of the many features of eXapath is that, once installed and hidden by drywall, it can be located using a common density-based stud finder. This benefits the home or building owner by enabling the addition of outlets from floor to ceiling. After generations of occupancy the structure remains prepared to adapt when new consumer electronics come to market...without disrupting the insulation envelope.

      In shallow inside 2x4” framing, outlets can be added from either side of the wall, in effect serving two rooms. Great for speaker wiring, HDTV, Mirror/TV’s, computer wiring, automation, that sort of stuff.

      With deeper outside walls important questions come to light. Today, most exterior walls are built using 2x6” construction. The wall cavities are then completely filled with insulation, except where studs, wires, waste pipes, and electrical boxes reside.

      Picturing the installation in an exterior wall, eXapath sits toward the inside of the cavity, in direct contact with drywall. Viewing the system from above note that eXapath has an “H” shape to accommodate our unique snap-in outlets.

      With a footprint of 3 3/8” square, 2 to 3 inches of space is provided for insulation. Once installed, eXapath becomes a permanent hollow pathway for low voltage cables enabling moves, adds or upgrades at any time.


      Whoa! Did You Say Hollow?

      This is a good example of the great questions customers ask...and how they are asked: 

      ”If that thing is in my wall displacing some insulation, what affect does it have on energy conservation?”

      The short answer is that eXapath does not present a problem with energy conservation...but it’s a complex question that deserves thorough investigation and a more complete response. Getting to that answer is, well, a science project in heat transfer. A look into the second law of thermodynamics. So, we asked ourselves, in addition to a complete answer, what other benefit can come from this investigation?

      Aligning with personal goals the question presents an opportunity for us to bring science out of the class room and into the real world. We’re asking our kids to participate in the exercise in order to help bring practice to much of what they learn in school. We’re involving them in problem definition, design of experiment, measurement, data collection, and analysis. With exposure to an academic project with real world implications, we hope the kids will appreciate that their studies do ultimately prepare them for bigger things. In this case we tie the learning to commonly discussed ideas like energy conservation and sustainability. The students vary in age and academic level but all study the basics including mathematics, global studies, earth science, language arts, etc. They’re actively learning of our interconnected world and often work with abstract problems in homework assignments. Their school teachers bring practice to lessons while reinforcing major points and we hope this magnifies their effort while adding more fun and meaning to the process.

      Get ready kids!

      Change...Why Fight it When You Can Master It?

      Stuff

      Let’s face it, we acquire plenty of stuff. As we amass belongings the value seems obvious. Once gathering dust, its relevance diminishes. It just happens. Making the time to organize, donate, sell, recycle or otherwise dispose of it takes effort...and the activity always seems timed precisely with more pressing issues...like yard work or filling out tax forms. So it grows...leading to “need” for larger spaces. If you really think about the “stuff” we collect, and assess it from a needs versus wants standpoint...much of the “stuff” offers little value. Once we have unnecessary stuff, the dilemma of disposal enters. Clutter. Why start?


      Like tropical fish, our footprint grows to the size of the aquarium we swim in...or something like that. I’m not suggesting that we live in confinement but I do recommend that, when planning our spaces, a thorough review of needs is more sensible than defaulting to anticipated overspill.

      While You're In There...

      Nascent opportunities for architects, builders and remodelers

      Sustainability. Hard to define...easy to toss around in conversation.

      I’m actively learning about sustainability. As I delve in, what becomes clear to me, is that I know a fair amount...but my proficiency pales in comparison to what remains for me to learn. Do you know this feeling?

      Bits, Bytes, and Speed...Whoop-de-doo!


      10Gb/s to start...scalable to 100Gb/s, so what?!

      In this age, it seems we’re drawn into a world of digi-speak, constantly inundated with impressive sounding jargon that can leave us baffled. Couple this with sustainability, and the subject matter quickly overwhelms.

      In a recent post, I marveled at the notion of using fiber optics within the home. Intel’s announcement about its “Light Peak” technology buoyed a significant market buzz.

      Their claim of a 10 Gigabit per second (Gb/s) data rate is surely impressive...and technically achievable...

      ...but what does this really mean for us consumers?

      Intel's "Light Peak" and You

      Imagine downloading a full length, high definition 3D feature film in several seconds. Picture an entire music library transferred, all of your home’s HD videos exchanged, or a complete hard drive backed up to a remote and safe location . . . instantly. We are heading in that direction, and it will happen well within the life expectancy of most homes being built today.

      To some these claims may seem outlandish, but remember how, just a few short years ago, you marveled at your first low-resolution digital camera, and the space-aged ability to save photographs electronically . . . easily sharing them with friends by way of mailed CDs.

      Fiber in the Home?


      Kudos to Intel for planning beyond next week . . . and for thinking big. To see what I am talking about click here: ”Light Peak to Connect Consumer Devices at Record Speed”

      The recent announcement of Intel “Light Peak” technology refers to an optical fiber that is 125 µm (microns) wide, roughly the thickness of a human hair. This notion of using strands of glass to route high speed signals within your home may impress, or . . . it may panic you.
