Green Build Bar Build Notes Suggestions Annotations

Notes-Suggestions-Ideas

I am going to mention ideas and suggestions on ways that will reduce your monthly bills in utility savings by incorporating the following examples into the Green Design of your building.  My suggestions will include: PV Solar Electric, Solar Water Heating, and Energy Conservation.  

The greatest use of your investment dollars will come by installing Insulation in the various parts of your building.

 

As a general rule it is cheaper to save energy than it is to create energy.  

It does not matter if this is in gas or electric. Basically: If you can save it you don’t have to make it.

The Department of Energy suggests for our region various levels of insulation

Ceiling: R38 - R60

Walls: R13 -R19

Floor: R25 - R30 

Examples of where to insulate. 1. In unfinished attic spaces, insulate between and over the floor joists to seal off living spaces below. If the air distribution is in the attic space, then consider insulating the rafters to move the distribution into the conditioned space. (1A) attic access door 2. In finished attic rooms with or without dormer, insulate (2A) between the studs of "knee" walls, (2B) between the studs and rafters of exterior walls and roof, (2C) and ceilings with cold spaces above. (2D) Extend insulation into joist space to reduce air flows. 3. All exterior walls, including (3A) walls between living spaces and unheated garages, shed roofs, or storage areas; (3B) foundation walls above ground level; (3C) foundation walls in heated basements, full wall either interior or exterior. 4. Floors above cold spaces, such as vented crawl spaces and unheated garages. Also insulate (4A) any portion of the floor in a room that is cantilevered beyond the exterior wall below; (4B) slab floors built directly on the ground; (4C) as an alternative to floor insulation, foundation walls of unvented crawl spaces. (4D) Extend insulation into joist space to reduce air flows. 5. Band joists. 6. Replacement or storm windows and caulk and seal around all windows and doors. Source: Oak Ridge National Laboratory

Following the above guides let's focus in on the areas that we discussed: Ceiling, Floor, Walls.

Ceiling:

1565 sq feet of estimated roof (see solar estimate).  Normal Ceilings are constructed with 2x12 lumber.  That is not enough space to provide adequate insulation with normal batt type insulation to meet the suggested level of R60.

My suggestions are:

• Put the Insulation on top of the roof eliminating any insulation in the cavities.  As we talked about I feel that when the Insulation is on the outside is like a person having a coat on.  It eliminates the hot or cold from entering.  
• Commercial Buildings utilize this type of insulation to stop the cold/heat from getting to the steel, because when the steel gets hot or cold it expands/contracts and is a big energy problem.
• They also make this in tapered sections to direct water easily.
• Exposed Roof System for Aesthetic purposes

I used Menards for a guide.  I suggest go to: the Roofing place at Vandeventer/44 area.  The old RSG under new owners. Johns Manville R-23.6 4" x 4' x 8' Fiberglass Face Polyiso Roof Decking Insulation Model Number: 1631150 Johns Manville R-17.4 3" x 4' x 8' Fiberglass Face Polyiso Roof Decking Insulation Model Number: 1631149 Johns Manville R-11.4 2" x 4' x 8' Fiberglass Face Polyiso Roof Decking Insulation Model Number: 1631147 Volume Pricing of $25.59 / ea- 24 units or more.

Floors:

• Suggested R Value 25.  Use 8 in Batt or Spray Foam Insulation.  8 Inch batt would be cheapest but not necessarily the best.

Green Possibility: It is possible to install a heated flooring system that would eliminate the need for HVAC heat system.  This type of flooring system is called radiant heating.  The heating is accomplished using electricity to heat wires, heat mats or tubes with liquid that is heated by electricity, solar, or gas.  

• Radiant Flooring systems warm the floor and the heat rises into the rooms.  This also eliminates cold spots hvac fail to work in.
• The use of this may depend on the final floor choice selected.  If it was going to be a tile floor I say yes.  Maybe not a good idea if a finished wood floor is chosen-discussion needed.  If you chose to install a concrete floor I definitely suggest a radiant floor heating system.

Walls:

• For a total Green Aspect (but not $ viable suggestion) Exterior insulation would once again be suggested.  Leaving you the option of utilizing the interior brick walls for aesthetic and old world design purposes.
• This same type insulation can be used on the inside but has to be covered to meet fire code.  1/2In Sheetrock.
• The Money saver is to build 2x4 framed walls with normal batt insulation and sheetrock.  But you loose the kool looking brick look.
• This is a final design choice you have to make.

Additional Points for consideration:

• Hot Water could be heated during the daytime easily with Solar.  I suggest an instant type heater installed for use when needed.  
• Liquid radiant flooring systems can be heated by Solar, tied into what ever system is used, or be independent with their own broiler system.
• Instant heaters without solar would require ½ the amount of pipes needed.  Only one cold water pipe to the fixture is needed.
• I work with Dale Or and Suzie with “Master Plumbers StLouis” permits and as my go to person to call for advice.
• I would like to introduce you to Slim Shady, Shady Jack’s son.  He is the one who built Shady Jacks and the 15+ bars they owned previously.  He knows his stuff about building bars and these old buildings.
• Everything in your place is going to use electricity.  Put in extra electric boxes or places to connect future lines.
• Along the same lines.  Buying Energy Star Rated Kitchen equipment when you can is a smart investment.
• Upgrades to electrical motors and fans on commercial equipment qualify for discounts from Ameren UE.

Solar:

1,565 sq ft estimate roof space from a couple of solar measuring satellite images- The “net cost” price quoted in the 3rd image is way off the mark.  Your system would be cheaper.

  

Notes:

• Using satellite imagery for determining roof size and using an electric bill of $400 / month.  Solar PV would cover the 50% or up to $200 per month.  $200 x 12 months = $2,400 yearly savings. 22 KW system
• Bill Size $500 Solar would cover 40%
• Additional Solar Panels could be installed on the West Wall of the Building- capture the afternoon sunlight.
• Additional Solar Panels could be used to create Open Air Spaces below where people could gather.  See picture above.
• Pole Mount systems picture above in the background.

• I’ve considered many things for your building.  The above suggestions would be my first choices and places that would save you money and create a green building to capture all the tax and other benefits available.  
• I welcome further discussion about anything I’ve mentioned and also assisting you with the renovations.
• For detailed and specific estimates I need to see: blueprints, design notes, floor plans.
• I have Green Building Financing Resources that may work to your benefit they will assist in: Solar PV and Water, Energy Conservation, Windows, Doors, Insulation, etc.

Midwest Solar News - via REWorld

With so much solar activity taking place on both sides of our nation, what’s happening in the heartland is going almost unnoticed. But it shouldn’t. Solar is beginning to grow like a prairie fire across the Midwest.

In a wide area stretching from Missouri to Ohio, the heavily-traveled Interstate 70 corridor, solar is beginning to catch on in a big way.  Missouri, Illinois, Indiana and Ohio now have a combined total of nearly 400 MW of installed solar capacity — enough to power about 80,000 homes. But here’s the real eye-opening statistic: solar in these states is expected to grow by nearly 50 percent this year, with roughly 180 MW of new projects coming online.    

Let’s look at Missouri as a case study. Showing strong growth over the previous year, Missouri nearly tripled its amount of installed solar capacity in 2014, according to the recently-released U.S. Solar Market Insight 2014 Year in Review. What’s more, Missouri also had more than half, 55 percent, of its new electrical capacity last year come from solar energy.

In 2014, Missouri added 73 megawatts (MW) of solar electric capacity, bringing its total to 111 MW. That’s enough clean, affordable energy to power more than 12,000 homes. The report went on to point out that Missouri’s biggest solar gains came in commercial installations, but residential and utility-scale installations increased, too. Of the new capacity added, 37 MW were commercial, 20 MW were residential and 16 MW were utility scale. Together, these installations represented a $187 million investment across Missouri — a 63 percent increase over the previous year.

Today, Missouri also ranks #2 in the nation in the number of professional sports facilities with installed solar systems.  Among Major League Baseball teams, both the Royals and Cardinals have gone solar, while the Rams and Chiefs are among NFL teams to do so.

To put the state’s solar growth in some context, the 111 MW of solar PV installed today in Missouri is nearly as much as the entire country had installed by 2004. And frankly, the state is just scratching the surface of its enormous potential.

The same, of course, can be said for Illinois, Indiana and Ohio. Today, there are more than 500 solar companies at work throughout the 4-state area, employing nearly 10,000 people, and bringing $339 million worth of new projects online last year. 

This steady growth across the heartland of America has helped the U.S. solar industry to grow to 174,000 workers nationwide — more than tech giants Apple, Google, Facebook and Twitter combined — while pumping nearly $18 billion a year into our economy. This remarkable growth is due, in no small part, to smart and effective public policies, such as the solar Investment Tax Credit (ITC), Net Energy Metering (NEM) and Renewable Portfolio Standards (RPS). By any measurement, these policies are paying huge dividends for both our economy and environment.

Net Zero Container Home Solar and Wind Energy

5 Container Layout for open concept living areas. Net Zero Energy use from 4k Wind Turbine and Solar Panels System. Passive Solar Roof Overhang Design that doubles as support for solar panels and blocks summertime sun rays.

This CAD design was originally made for a client who was interested in a container home design. After the costs to buy, renovate, and build a container home outweighed the cost of a larger and roomier Post Frame Building design they decided that maybe a container home wasn't the best fit for them and their growing family.

The Clients also requested a Rock Climbing Wall incorporated into the Home Design- ie Must Have. This was also the reason behind the design of the Container on its end sticking up above the remain home. With a few windows the container can also be used for a Natural Air Movement Home Ventilation Feature as well as house the Wind Turbine. This meets my design goals of a building feature that has 2 or more benefits is always a worthwhile addition!

There are no interior plans for this design. If you would like an interior design let me know and I'll work one up.  The usable interior floor plan space is 20- 40 feet wide (wooden truss system) x up to 40 feet long with up to 16 feet tall ceilings.   This allows plenty of space that could incorporate a variety of designs.

Frequently Asked Question

What if I move? You can simply assign your solar lease to your the homeowner. If you’d prefer however, you are able to buyout the lease and
move the equipment to your new home.

What if the system doesn’t work? We are confident that it will, we track over 50 of our installed systems over the past several years, and
those systems have averaged 6% more annual production than expected production. In the event that the system doesn’t produce as
expected, your lease payment will be reduced so that you will never pay more for solar energy than you would otherwise for utility energy.

Will hail damage the panels? The solar panels are rated for a 1” hailstone flying at 55 MPH perpendicular to the face of the solar panel…the
solar panels are designed to withstand large hail impacts.

What about maintenance? There is minimal/no maintenance required for these solar systems since there are no moving parts. Maintenance
for a Leased System is included in the lease.

Proof Positive Clean Energy Solar PV Works

It is a 7 kWh system consisting of 32 panels and two inverters, On a very good day we will produce 52 kWh. Average is 42 kWh. We normally produce more electricity then we can use.

"This is directly copied from a fellow Google Plus Friend" I'm sharing it with my readers of the blog to show that it is possible to have great things that are run by solar power."

Last year we added a Nissan Leaf and now drive around town for FREE.  Saving over $3000 in gasoline a year. And no longer subservient to middle east oil prices.

One of the biggest energy reduction was installing a variable speed pool pump. Reducing usage form 12,000 watts to 1,200 watts a day.

Addition reduction was changing to LED light bulbs through the house and garage.

Eliminating Solar Panel Fires from Wire Faults

What could have stopped the solar panel fire on the Webster Grooves School in StLouis MO?

 Solar Panels that utilize the M215 MicroInverters made by Enphase Energy could have stopped the Solar Panel fire before the fire started.

I realize that is a rather boastful statement made by someone who promotes, sells, and installs Solar PV systems for the StLouis Region and chooses to utilize Green Building in all their Construction Activities.

But the Great Minds behind [The Next Generation of Microinverter] the Enphase M215 MicroInverters that provide 96% CEC efficiency equals more energy production also built the M215 MicroInverter with a GFI [Ground Fault {Detection} Interrupt] shut off.  Similar to GFI Electrical Outlets pictured in the photo below.

Must Have For Safety  GFI Electrical Plugs are required by all USA building codes and are located in your Kitchen, Bath, and Laundry Rooms and other areas close to water sources- Scotty, Scotts Contracting

All M215 MicroInverters will shut off if there is a fault detected. inside of every microinverter is a GFI (Ground fault {detection} interrupt) switch and if there is a fault, it will stop exporting power within 30 milliseconds per UL1741standards.

• {Scotty Adds-

• Just Like the GFI electrical plug in your Bathroom and Kitchen works!
• I had to look up 30 milliseconds to see how fast it was and here's what wiki supplied: 

• 20 milliseconds — cycle time for European 50 Hz AC electricity or mains grid
• 24 milliseconds — minimum ignition time for a U.S. Rockets company solid rocket motor
• 31.25 milliseconds - a hundred twenty-eighth note at MM = 60
• 33.3 milliseconds — the amount of time one frame lasts in 30fps video
• 41.708 milliseconds — the amount of time one frame lasts in 24fps video or film (actually 23.976fps for most films)
• 50 milliseconds — cycle time for the lowest audible tone, 20 Hz}

Enphase Energy M215 MicroInverter

Overview

The Enphase M215 is the world’s most efficient microinverter.

Based on Enphase’s third generation technology, the M215 incorporates the latest innovations in power electronics and custom microchips to deliver 96% CEC efficiency and a range of patented performance features that maximize the performance of 60-cell solar modules.

In addition, the M215 is light weight and offers a “single-bolt” mounting bracket that makes installation easier than any other inverter on the market.

Here's my conversation with the Good People of Enphase Energy and links to the Articles about the Solar Fire

Scotty:

“Recently in St Louis, MO a solar panel supposedly caught on fire on the roof of a local school...it hasn't made much news other than deemed solar fire on school. Could one of your Innovative MicroInverters215 sensed the ground fault and stopped the production of electricity and thus eliminated the fire since it would have stopped creating electricity? There is a few local builders who have been considering adding solar but have raised questions in re. Thank you for your time and assistance. Scotty”

Enphase Energy 1st response:

Hello Scotty,
Thank you for contacting Enphase Energy!
That's a scary situation! Sorry to hear that it happened!
Safety is one of the aspects of our system that we are very proud of. The old style of solar array uses solar panels in series, which ends up with High Voltage DC wiring. Our Microinverters converter the DC to AC right at each panel, which is inherently safer. Here is a link to our informational page that speaks to our safety, which also has a link to PDF:
http://enphase.com/explore/enphase-technology/safe/
Here also is a link to a video demonstration on our YouTube channel, which shows the difference between a DC and AC arc fault:

Scotty:

Thank you for responding to my question.  I'm already a fan of the M215.  Can the M215 sense a ground fault and stop producing electricity?

 "Could one of your Innovative MicroInverters215 sensed the ground fault and stopped the production of electricity and thus eliminated the fire since it would have stopped creating electricity?"

Thank you for your time and assistance.

Scotty 

Enphase Energy (2nd Answer):

Yes! Our Microinverters do detect ground faults and halt production. 

Please let me know if you have any other questions, or if there is anything else I can do to assist. 

Thanks,

Enphase Energy (3rd Answer from Contact Form on their website):

Hi Scotty, 

The inverter will shut off if there is a fault detected. inside of every microinverter is a GFI (Ground fault detection interrupt) switch and if there is a fault, it will stop exporting power within 30milliseconds per UL1741 standards.

    Webster Groves School District May 18

Solar panels on the roof of Webster Groves High School caught fire today. The fire, which was contained, caused no interior damage. Some water used to put out the fire seeped into a classroom.

The cause of the fire has not been determined.

The High School will have classes on Monday.

Like I wrote earlier the Great Minds at Enphase have already factored this safety feature into the Design and Construction of their Innovative MicroInverter the M215. Couple that with the great and timely feedback from their Websites, Twitter Accounts, and Email Correspondence-
