Let’s Chat About Energy Conservation

John Portrait In-Text ImageToday we feature a conversation with green builder John Hill. He’s a graduate of Appalachian State University, a leading school for sustainability education and home to the longest running sustainable development program in the nation.



Q: Have you always been passionate about protecting the environment?


A: I’ve been interested in renewable energy technology since high school. So when I was ready to attend college, I researched universities and found Appalachian State. They had been teaching appropriate technology for a couple of decades and their list of courses looked super interesting. I worked my way through all of the course work and then some, eventually earning a degree.


Lets Chat About Energy Conservation - In-Text Quote 1 I really enjoyed the renewable energy courses as I thought I would, but ended up being more passionate about energy efficiency. The building science and sustainability courses forced me to consider the bigger picture of our energy use and consumption, as well as its generation. It was an eye opener to see how many systems and details need to work together to make the most durable, comfortable, and efficient buildings possible. As it turns out, our built environment uses a tremendous amount of the energy we produce. Also generating power is one of the largest impacts we have on planet earth and therefore on all of its present and future inhabitants. Which means building smarter, smaller, and more durable buildings can make a real impact. Low hanging fruit really.



Q: How did you get involved in the green building industry?


A: Once my wife and I settled into Boone, North Carolina (where Appalachian State is located), we realized that rent costs were pretty darn high. We decided to build a house while we were there, thinking we could use some of the strategies and technology that I was learning in school. The building business was booming in the area at that time and I couldn’t find a contractor interested in taking on a small alternative home, so I entered the building industry out of necessity. My wife and I, along with friends and occasionally a hired builder, eventually finished the project. We ended up with a great little house and a great big education. I later went to work for one of the builders that had helped with the project and I’ve been working in the field since.



Q: What were some of the special features of your first green house?


A: Our main design goal was to create a low-impact home that would appeal to people because of its functionality and comfort – not just that it didn’t cost a lot to power. We spent a ton of time designing out wasted space, and figuring out how to get multiple uses out of certain areas so that we could keep the footprint small. That was the hardest part. We used high ceilings, plenty of daylighting, and an open floor plan to help the space feel big. We designed one bedroom to open up to the great room so we could expand the living space for entertaining.



Lets Chat About Energy Conservation - In-Text Quote 2Fortunately, almost everything you do to make a house more efficient also makes it more comfortable. For instance, by using heat recovery in the ventilation system, you not only save on heating and cooling energy – the fresh air that supplies the house is a more comfortable temperature. By orienting the house to the sun and using passive solar strategies, you can capture solar energy during the winter while avoiding overheating in the summer. That’s a win-win for year-round comfort. Of course, we made the shell of the house super resistant to heat and air transfer and chose efficient appliances, all of which increases performance and lowers energy use. Our solar water heating system was significantly more complex and expensive to install than a traditional water heater, but month after month, it used free solar energy to do most of the water heating, offsetting around a quarter of the house’s energy needs. The payback for that effort is more than financial – it just feels good to take a shower and know the water was warmed by the sun, not a power plant or oil well. In the end, the home we built operated on less than half of the energy of a typical new home in that region and we made plenty of mistakes on our first try.



Q: What’s new in the green building industry that’s exciting to you?


A: I really like the tiny house movement for exposing us to how much downsizing is possible while maintaining or probably improving one’s lifestyle. I also dig electric drive vehicles, especially bikes. I think plenty of us could trade a 5000-pound auto for a 50-pound electric bike and have a hell of a lot more fun getting around, using a fraction of the energy.



Q: What are your top energy saving tips?


A: Localize or regionalize your diet. Live near where your main activities are in the smallest residence imaginable – and think hard about this one! Turning off electronics that you’re not using is helpful, too.



Q: How do you envision our world in 50 years?


A: We should all be living in buildings that produce more energy than they use and zipping around in lightweight electric vehicles powered with renewable sources. Maybe by then we will no longer be harming our planet, but sustaining it and repairing it – leaving it cleaner and more resilient for future residents.


Honda’s Smart Home

Yes, that’s right. Not a smart car or a smart phone – a smart home. Considering that 3D printers are printing food these days, a smart home is not such a stretch. In fact, Statistica says revenue for smart houses in North America will hit $9.4 billion next year – a 42 percent jump from 2012. Honda’s smart home hints at the direction we’re heading, and it’s unique in that it was developed to show how both a house and an electric car can be powered by renewable energy. According to Michael Koenig, the project leader for the Honda smart home, the initiative was designed to showcase “Honda’s vision for zero-carbon living and personal mobility.”



Welcome to the “Zero Net” World


Welcome to the Zero Net WorldAll of the energy used in the house and to charge the car is monitored and controlled by a Home Energy Management System (HEMS) designed by Honda. Solar energy is stored during the day and then used at night when more electricity is demanded and the car needs to be charged. All in all, the 1,944-square-foot Honda smart home actually produces more energy than it uses – 75% less than a typical home – which makes it a “zero net” home. It’s fitting that Honda’s smart home dwells in an entire community that’s zero net, UC Davis West Village in California – the largest of its kind in the nation.



Bye-Bye Old-School Heat and AC


Bye-Bye Old-School Heat and ACWhat may be most amazing about this home is that it remains comfortable to live in without an air conditioner and heater. This is achieved in a number of ways, from sloping eaves on the windows, to thicker walls, to a roof that reflects light. But the real star of the heating and cooling show is a unique heat pump system that regulates the indoor temperature. Holes are dug into the ground to use the earth’s temperature to heat or cool water, which is then run through the house in pipes under the floor and in the ceiling on the second floor. This isn’t a new idea. What is new is the size of the holes they dug. Typically, they’re dozens of feet deep and small in diameter. Honda’s smart house heat pump holes are 24 inches wide by 20 feet deep. According to Jonathon Woolley, one of the engineers at UC Davis who designed the system, this can reduce the cost of the heat pump system by 90 percent!


With innovation like that, smart homes could become mainstream before we know it. To learn more about Honda’s smart home, check out this video.



The Mind-Blowing Benefits of Wind Energy

From creating thousands of new manufacturing jobs to being a clean and renewable energy source, wind energy has been the energy industry’s darling for more than a decade. Here are some interesting facts from the American Wind Energy Association (AWEA).


Wind power in the U.S. is…


  • Generating electricity with zero emissions, pollution and water use
  • One of the fastest-growing sources of new electricity supply
  • The largest source of new renewable power generation added since 2000
  • The employer of 73,000 people in more than 500 manufacturing facilities
  • The generator of enough electricity in 2014 to power the equivalent of 16.7 million homes



Blow Off Your Power Bill


Blow Off Your Power BillConsider this: according to the AWEA, a small wind turbine could generate enough energy to cover the electricity costs of the typical American home. It’s true that a small wind turbine isn’t cheap – you’re looking at least $4,000, but you can fully recover the cost in as little as six years. The U.S. government also gives a 30% federal Investment Tax Credit for fully certified wind turbines. If you’re thinking of buying one for your house, here’s the list of certified small wind turbines.


As appealing as never having to pay your power bill again sounds, wind energy is, unfortunately, not for everyone. There are some basic requirements:


  • You live in an area that has adequate source of wind
  • You live on at least one acre of land
  • Your area is zoned to allow wind turbines
  • Your electricity bill is $150/month or more on average

If you’re still interested, learn everything there is to know about small wind electric systems in this consumer’s guide from the U.S. Department of Energy. And you can still support wind energy by joining the AWEA’s community of advocates.
