Lessons from one’s children

Posted on April 7th, 2007 in Share Your Experiences by Bob W

A 100-car plus coal train rumbling through town caught our children’s attention last summer in a different way.  This is a typical train that runs through town a couple of times per day, at least that we know of.  The parent-children volley was a tag team between my 7 year old twins, 9 year old and myself.  It went like this:

‘What’s that stuff in the train cars?’ 
‘Coal.’ 
‘Why is coal on the trains?’ 
‘Electricity’. 
‘Coal makes electricity’? 
‘Eventually.  By burning coal, power plants boil water, which produces steam, which turns large turbines, which generate electricity’.  (Long pause.) 
‘Burning things pollutes the environment’.
‘Yes, it is absolutely not the best solution.  Let’s do some math… (calculations) That’s quite a few tons of coal day after day’.  
‘Where else can we get electricity’?
  Ding!

We got home, looked around online, found http://www.powertochoose.org/ and made the switch to Green Mountain energy.  At least we made the attempt, more on that later…  The kids were ‘proud’ of their parents for making the right choice about using wind generated electricity.  I was more excited about their making a difference.  Easy to get so caught up in life or believing my own space on the planet can’t make a difference.  Easy to lose consciousness that it starts here, and then with the next generation, etc.  Basic stuff, right?

This is where ‘dork dad’, as my wife says, engaged.  We went around and looked at all of the electricity that we used, that we could see.  We then began calculating watt hours (the number of watts something consumes in an hour) of light bulbs and various appliances. 

We had over 50 incandescent lights in the house (excluding the small chandelier bulbs, whatever they’re called) that averaged between 60 and 100 watts each (If all were on concurrently, those alone would use around 4000 watts of electricity per hour, or 4 kilowatts). 

Kids run out the door to catch the bus or play, and invariably leave their light fixtures on.  240 watts each.  Ceiling fans.  Nightlights.  Closet lights.  TV’s.  Bathroom lights.  Radios.  All consuming.  $450-$500 electric bill?  Duh.

Light bulbs were the ‘low hanging fruit’.  With a trip to Costco, we purchased CFC’s which consume 13-15 watts each but illuminate just as well, including recessed lighting (only some work with dimmers, research first).  Then nightlights.  These things typically burn 4 watts each, but are pretty much on 7X24. 

We found, again at Costco, ½ watt LED nightlights that last a long, long time.  The type we found also have color selection, my wife was able to set the color, by pushing a button, to the individual room.  I got a passing grade on that one.  She’s still getting used to the CFCs; they’re not ‘instant on’ but gradual. They do take a short while to warm up.  Fifty CFC light bulbs later, a package of ½ watt LED nightlights, and we can save (if all lights are on at once), around 3300 watts per hour. 

We spent around $60 on this project, which was recovered in the first month.  I firmly believe by being more conscious, as well as making the switch made this payoff occur so quickly.  Our electricity bill has averaged 25% lower month over month vs. last year same months, since September ‘06.

The fridge, washer and dryer were next.  Front load GE washers and dryers replaced the Maytag top load washer and older dryer.  We have lowered water consumption by over 1000 gallons per month.  In terms of 1 gallon milk jugs, that’s a fair amount.  Electric consumption went down again due to better spin cycle on front load, and more efficient dryer with moisture sensors that shut off automatically, not when the dial makes it around to the ‘off’ position.  With the fridge, the kids must know what they want before they open the door.  The coils are vacuumed every few months as pointed out in other articles on this site. 

Found and repaired drafty areas in the home; door jams with additional weather stripping, areas in attic with uneven insulation cover (if you place your hand on the ceiling during high temperature differentiation days; colder or warmer outside than in), you can feel areas that have less insulation cover in the attic.  Thanks kids for the eye opener.

Solar is next if the HOA allows it. A bill was recently passed that may eliminate the need to gain approval for adding solar, which is encouraging.  We’ll see how that pans out. 

Closing off on Green Mountain Energy… I live in a ‘Regulated’ area and cannot switch; Tri-County Co-Op is the monopoly of choice for now.  Make the switch for us until we’re able to do the right thing here. 

With the TXU announcement yesterday of ‘no unilateral action’ shutting down plants, Disregarding $2.5Bn profits last year, we should all think about what is really going on, and what we really need to do.  Smells like energy providers out west some years ago.  What was the name of the energy outfit that was involved?  Where is California now with being more conscientious?  Most of the time ‘conservation’ runs against the grain in casual conversation.  We need to each do the right thing to make an impact.  Thanks to the editor for bringing awareness and a forum to facilitate a positive change. 

A tankless heater, then HVAC replacement

Posted on February 15th, 2007 in Share Your Experiences by Brian LaCroix

We bought our home in August, 2006.  The home is an energy hog.  Immediately, we noticed several things that just sucked up the energy:

  • Skylights with old glass (no IR/UV protection)
  • Single pane windows throughout
  • Old (ok, ancient) HVAC system
  • limited attic insulation
  • Old, near end of life 50-gal water heater in an inside closet

To be fair, the house did have two big things going for it which are design things that cannot change:

  • The house is situated on the lot and 80% of our windows face north/south. 
  • We also have two beautiful Live Oak trees on the south side, shading the windows about 80% of the time - minimizing solar heat gain. 

These two things are definite plusses, as it’s very hard to move your house. When we first moved in, we bought an energy star Fridge/Freezer.  The house had a washer/dryer, so we decided to use that for a bit until we get some other items fixed up first.
 
The very first thing (besides some interior redecorating) we did was pull out that old water heater.  It was about 10 years old.  It was also inside the envelope of the conditioned portion of the home - which means it is “negatively” pressurizing the home (pulling outside air through all the cracks in the home to feed it’s gas burner).  I understand that negative pressure = bad.  The closet it was located in shared the wall to the garage.

We installed a Bosch 250NG tankless heater on the other side of that wall, inside the garage.

This took care of several things:  (1) removed this source of negative pressure, (2) removed the passive heat exchange between the tank and the inside conditioned air and (3) gave us another closet - one can never have too much storage!  This install is going to save us $80-100/year and the tankless units last a lot longer - so in the long run, this unit is going to save us money every month… and last longer - more than paying for itself over the life of the unit.  Economical and environmentally friendly… this is the model that more products need to gain traction and get mass deployment.
 
Next month, we are getting our HVAC replaced.  Our current unit was built in ‘86… so it’s 21 years old.  the AC compressor has stuck valves (per the HVAC guy) further decreasing it’s capacity.  We are replacing the whole system with a 16-SEER multispeed, dual stage system.  We aren’t going for the top of the line systems, as there is a breaking point between capital cost and operating cost - I am not going to pay a ton of money just to save a little energy… these things must make economic sense.  During the summer, we are going to save a TON on electric charges with this new, much more efficient unit.  For the record, we set our thermostats back (automatically) when we are both at work.
 
We decided to wait on replacing the skylight glass - and take advantage of the solar gain all winter.  In the next couple months, we are going to get the glass replaced in both our units with IR/UV blocking glass from the manufacturer of the skylights.  When we first moved in, I climbed up on a ladder to clean the blinds in the skylight… and just about burned my fingers, as it was letting in that much heat.  That can’t be good for the AC bill!  This is going to cost about $400 for two skylights - that will EASILY pay for itself over the life of the glass (and cut down on sun bleaching of our home’s interior).

After the HVAC is in, I am going to climb in the attic and seal all the rigid duct work myself (rigid duct work is more efficient, as it has less drag internally, but it leaks like crazy - causing a HUGE negative pressure issue - unless you seal the seams) and put on additional duct insulation, then install additional attic insulation. 

These two projects are going to also be relatively inexpensive ($600-800 total) and pay back huge dividends ($125-150/year).  By removing the negative pressure created by leaky ducts (at just a couple hundred bucks), I suspect this project will pay for itself in the first year - two at max.  Again… economical and environmentally friendly.
 
The windows are something that will take a bit longer, but over the next 2-3 years, we will be replacing the windows.  I’ve actually ran simulation programs (RESFEN 5.0) to compare windows in our home.  I was really disappointed in the savings for all the marketing hoopla that’s out there (but to be fair, the trees and position of our windows were limiting the savings - if you have more exposed windows, your savings will be greater).  Going from single pane to dual pane with argon gas and low-e… we are only going to save about $250-300 per year at a cost of $7-8K.  That’s about a window a year.  Economics simply don’t work in the favor of window replacement.  I was really bummed by this.  We have decided to make a conscious decision that the better sound insulation and lower energy usage (from an environmental perspective, NOT an economical one) is worth the upgrade, but we are prioritizing other things first.
 
That leads us to those “other things”.  We are planning to replace out top loader washer with a Bosch front loader.  We are also looking at replacing the old, inefficient dishwasher with an Asko highly efficient model.  We have done some things that are certainly not what all environmentalists would want - we are installing a larger jacuzzi type tub in the master bath, we have a dedicated 20-amp circuit for a fancy shmancy espresso maker and we have an outdoor jacuzzi.  I believe in helping the environment, but I also believe in enjoying life - we just try to limit our impact on it.
 
All things considered, I think these upgrades will take this environmentally unfriendly house and dramatically lower it’s “carbon footprint” (as that’s the current buzz phrase). 
 
I would certainly entertain grey water catchment systems - but think they may be a bit more economical on new construction, where you could install TWO meters - one going to places you are going to recapture the water/hook to the lawn sprinkler and one for the rest of your water - since the sewage costs are the highest part of your water bill… without removing that, I find it hard to believe that grey-water system could pay for itself.
 
I would love to install solar or wind or some sort of alternative energy generation solution… but they just aren’t economically practical at this point in time.  I’m definitely watching the thin film solar industry with great anticipation.  If they can cut the overall initial costs in half… I think we would have something that would be adopted on a massive scale.
