Benefits of a Class Demonstration in Solar Village

IMAG2772

A class act blower test was conducted in the 2002 Solar House. The demonstration was put on by the ArchE 372- Residential Renewable Energy Design class. The purpose of this special visit was to teach the students about how a blower test is conducted but then also be able to set up a blower test as part of a case study in the course. The reason why the students need to learn how to use this apparatus is that it will help them tell homeowners where air leakage is in the home. Air leakage is a big source of wasted energy. It could be a waste with air conditioning or heat because of the fact that systems must work extra hard to keep that stable ideal temperature within the home. Wasted energy equates to wasted money and by conducting this test homeowners face savings all around and create a more comfortable environment at the same time.

The students used a Retrotec house leakage analysis system. The typical blower door set up consists of a temporary door panel that seals within a door frame. All other doors and windows must be closed when this test is being conducted. A fan within the temporary door is stabilized and is able to measure the airflow. A two-channel gauge that measures pressure helps with calculations. Create a negative pressure on the inside of the home and push the positive to the outside. The pressure imbalance gets measured and can help determine the size of the leak. Fan speeds can be controlled but when everything is set up the fan must be spinning fast for proper results to be read. Soon enough you will feel air seeping into the home from the leak points as its getting sucked in from the outside.

The 2002 home had a lot of air leakage around the seams of the door. Standing in the house while this test was occurring students could physically feel the drafts of air.  The weather stripping had aged and worn down too much but thanks to this test, more energy awareness has been made. To immediately resolve this energy loss and leakage problem the students made some adjustments. At the same time as running the test they applied duct tape and tissue to line up the door. Immediately, results could be seen on the measurements of the gauge towards a positive direction. The students recommended that once a year homeowners check the weather stripping around doors and windows. There are nice seals that can be used but when in a pinch, tape works to seal off a door. Another method along with rolling up a towel and laying it along the bottom crack of the door is to caulk any stationary house components like window frames. Keeping up on energy savings leads to a happy eco-friendly home!!!!!

United States Army Pushes for Solar Power

There are some things that every soldier should know about and there are things that every American citizen should be proud of. Not only should we be thankful for our soldiers time in enlistment but be proud that the Army is taking huge steps in the effort to use sustainable energy like solar power. The Army Times is a newspaper that not only enlisted members can subscribe to but the public as well.  The paper features on a regular basis the next best thing with solar usage. These feature articles can be for various sustainable technology with different things in the field and what’s new on base relative to going green. Solar highlights are right next to various articles applauding the brave and the more inspiring stories of how equal standards are for all military members now. As you can see, the Army holds reducing a logistics foot print with solar power in high regard.

Hostile Fire Detection Sensor

Hostile Fire Detection Sensor

One of the ways they are using solar technology in the field is to have a battery free sniper finder. The Hostile Fire Detection Sensor nicknamed Firefly is a 360- degree surveillance apparatus that can study enemy fire, locate where it came from, and then direct the soldier on exactly where to take aim. This aids the soldier directly in finding sniper attacks in Afghanistan. This Firefly sensor can be attached to a wall or onto a soldiers’ back and uses a combination of acoustics or shortwave infrared detectors to work. This Firefly unit combines with the RENEWS technology which is already in place in the field. The acronym stands for Reusing Existing Natural Energy, Wind & Solar system. This is a kit that uses solar or wind to recharge battery packs soldiers use in the field. Changing power sources can be a hazard on the field. It only makes sense for the Army to utilize solar in a mobile way by having RENEWS kits provide the sensors with 1.2 kilowatts of continuous energy. The connection of these two systems has aided in further study of hopefully making other small unit power collaborations and have them be all the more “ARMY STRONG”.  Thank you Army for your service to our country and I am proud to hear about the progress to use more sustainable methods in the military.

Halycon Shades in the Chameleon House

Halycon shades were connected to our Chameleon Automation system. The shades pull down and can still let visable light in but keep heat out. This is because any heat from the sun and UV rays do truly affect indoor climate. With this product 99.9% of the UV rays are blocked. The Halycon Shades are just a little transparent at night so it would still be advisable to hang curtains by them. That way all you have to do is pull curtains shut to help keep more privacy within the home at night. This was added to help the techniques in the house of being more sustainable and to help save energy in regards to heating or cooling. The Chameleon automation system knows the times when the house is puling peak energy in from the solar panels, the temperature on the outside and inside, then also what the occupant prefers. Then automatically the shades will draw down in accordance with how to help the house keep cool by blocking sunlight, or to stay up to help keep rooms warm. Halycon shades have little motors in them that aid in the automatic process. The shade motors hooked up to our Chameleon system encourage the overall home to be more energy efficient because the home is using techniques to adapt to the environment. Its all about that adaptable lifestyle with this home. Any reduction of use on our small duct- chiller system the better. Blocking out sunlight with normal shades in a traditional home is a way to help with passive solar techniques. The shades simply block light to prevent unnecessary heating of the home. The difference with our shades is heat gets blocked but light still comes through. We could still see outside as if you have open windows in the daytime but don’t have to deal with heat. They are a LEED certified product and this means a potential customer can trust that  Product information can be found at www.halcyonshades.com

Hyload modified PVC membrane

This is an awesome product that graced the roof of our Chameleon House. This was an element that was put on our flat roof to block out water, and serve as a physical buffer between panels and the roof. This served as a great staging area for the home in conjunction with the solar panel set up. Another purpose it served well for was to prevent actual leaks and to aid in the movement of water off of the roof. Modified PVC membranes have many advantages that range from being lightweight and easy to manage, to having a very good seam strength. The fact that we have to transport our Chameleon House to California meant that any kind of element on the roof has to have a certain sense of give so to say. The tough, durable, and flexible characteristics are what is required for our Chameleon House. The Modified PVC membrane can restrict movement without having any type of cracking or splitting within the roofing material. Our roof membrane was a white color, to help reflect sunlight thus adding to the element of passive solar use. The PVC hyload membrane serves a better job of being more efficient verses the alternative black roofs that most homes utilize. The darker roofs add a lot of extra unnecessary heat because the dark color basically absorbs the sunlight and holds a huge build up of heat. Keeping a lighter color on the roof is ideal because solar panels are more efficient at cooler temperatures anyway.

Tower Garden Produce aided in Chameleon House Dinner

During the solar decathlon we had to host a dinner party for 8. This was a chance to show off our house and at the same time compete. The stove and oven had to be in working order along with having a comfortable sitting room temperature. The display of lights had to be on to better show how our house had a warm ambiance with the perfect placement of light features. Team members cooked for representatives from other teams and a VIP guest. Our Very Important Person was Chancellor Schrader. She helped us host a very successful dinner made by our own Chameleon House Crew. The fancy menu that was created included tasty treats such as salmon, rice, green beans, and wong- tong appetizers. Peanut-butter chocolate pie was the delicious dessert that many people chowed down on. The Solar House chefs included fresh herbal items from our tower garden donated from Missouri S and T alum Paul Sticker. This tower garden was on display through out the Solar Decathlon event and added a homey natural element to our home. Not to mention the variety of herbs added a nice aroma to the house. “Dr.Paul” says that the benefits are all around for this thing and boy do we agree. We used this self-sustaining eco-friendly product and fell in love. It Uses 90% less water and nutrients than traditional growing. The tower garden is beyond organic and also grows 20 plants in 30 to 50% less time than soil. Water conservation, food safety, land scarcity, and soil deprivation are problems we all face today on a global scale. But with this easy to use tower garden those issues can be met head on. Not only doing your part to make this world a better place but you can personally benefit from the natural foods with the healthy nutrients they provide.

Air Ducts in the Chameleon House

The Unico system® was added into our Chameleon House and I must say that we loved it for the high effective efficiency. The supply and sound attenuator duct is a small duct high velocity system.  It mixes air verses slowly permeating like with what happens with a conventional system. This makes the air flow even faster with a more even temperature through out the home.  There is a fast air exchange, with old air for new air being switched out at a rapid pace. The rapid switching of outside and inside air is very important in the fact that we have such a well-engineered house that results with a very air tight home. Another benefit of this product is how it is a fairly silent product overall. The reason for this is that there is the addition of a Unico sound attenuator that gets added to the end of a branch run. The combination of the sound control elements, insulation to prevent condensation from forming and the flexibility of the supply tubing made for an easy to install duct system overall that fits into any space. Over traditional HVAC systems this product eliminates drafts and can reduce the relative humidity in an additional thirty percent.

Personal experiences from the team say that this is a very easy to install. There was great response from the public tours as well during the Solar Decathlon 2013 held out in Irving, California.  They loved how the team blended the ducts in with our cloud like system that was put in the ceiling to serve as a sound absorber. The public also liked how cool our home felt at the end of the day in the hot California sun.  Upon entering the Chameleon House for tours people immediately noticed how along with a combination of our concrete flooring, placing of windows and this small duct high velocity system an overall comfortable living environment could be displayed and felt.

Save the Rainforest with Solar Power!

Any thing to help stop illegal logging is extremely important. There is now technology for smartphones combined with solar power to help watch over the rainforest and catch the bad guys. It’s always a challenge to watch over big amounts of land for banned logging activity. So, any kind of advancement towards combating these problems is a breath of fresh air. There is going to be a combined network of solar smartphones listening in to the noises of the rainforest and distinguishing the sound of chainsaws. They will be placed around the rainforest sporadically and work continuously. The phones can hear chainsaw motors in an area over .5km radius and this real time data will be sure to catch illegal logging.

It takes no time at all for some illegal logging to take a huge toll on protected ecosystems. Current methods can take time because its just using satellites to look for swaths of cleared land. This is slow and only useful after the damage is done. By the time someone can attempt to stop the chainsaws the loggers are well on their way. Having the real time network set up of smartphones all equipped to listen to audio frequencies gives conservation agents a fighting chance. These smart phones will then send out alerts when the audio of chainsaws gets picked up. A non-profit called the Rainforest Connection will be utilizing this first in Western Sumatra. They will be the ones in charge of an internet- based central database but alerts get sent to agents in charge of individual sections of forest.

Rainforest Connection will start out with 15 Android phones but hopes to create a stream of reuse by accepting outdated smartphones for this project. That is such a great way to not only save the rainforest but keep electronic waste out of the landfill. The main goal is to not only save the forest but to allow expansion of new technologies by allowing crowd sourced projects. The more systems set up the better! If you send your contact information along with the phone donation, Rain Forest Connection will be able to tell you exactly where your phone is being put to use.

Ameren UE helps to create a dream come true for a small restaurant!

Outside patio with a view of the Saint Louis Arch in the background!! The Gate way to the West!!!

A cute little establishment in Saint Louis is making that big leap to going solar and they are going about it in a unique way with the help of Ameren UE, which is a power company! They are building solar canopy carports in their parking lot adjacent to the Ameren property in Saint Louis. Vin de Set is a French restaurant in a historic building that dates to 1876 and owned by Paul and Wendy Hamilton.  The building is known as the Centennial Malt House and originally it housed the Schnaider Brewing Company.  There are other things currently housed in this building such as Moulin event spaces and a PW Pizza as well. Vin de Set is the place to be for that view of downtown Saint Louis, view of the Arch, good food, fancy drinks and now a chance to see a Solar Panel array.  Solar technology on this historic premise is to be deep in progress by the end of September. The photovoltaic system is expected to be 25- kilowatts and the carport canopy will cover a long row of vehicles. This canopy backs up to the east side of the lot and Ameren UE will buy any extra power from the restaurant. The cost of the project will be $98,000 but there are a lot of things in place currently to help lower the cost. Some federal help will be through the Solar Investment Tax Credit and Ameren offers a $2 per watt of installed solar capacity. Ameren will offer this amount up to $50,000 via project installment.  If you are ever in Saint Louis be sure to stop by this fun restaurant called Vin de Set and treat mom or your significant other to good eats. Of course the ultimate treat in my books would be to check out the Solar Carport Canopy and sip on some wine!!

Check out the Ameren UE website and get in contact with them before you do your own solar project! There very well could be rebate programs connected with this awesome utility company. They even have a get started page to really help your home or business along.

Chameleon House usage of Enershield

Almost applied all the way with second coat!!

Almost applied all the way with second coat!!

On our Chameleon house we have use of an awesome material called BASF© EnerShield©. It is a system that creates a pretty good air and water- resistive barrier on most wall assemblies. Enershield goes on in a liquid manner by just being painted on. Quick application with a paint roller is quiet luxurious. For such an easy application this sustainable material accomplishes a lot. Utilizing the EnerShield is a step to reduce use of extra insulation like products. Some bragging rights we will have with this product is that the air barriers really do reduce building energy consumption by up to 40%. We are very proud of the fact that its water based and when being applied was not undergoing any scary exothermic reactions and not flammable in liquid form. The usage of this helps to reduce emissions that much more. The Enershield has VOC levels that are below maximum levels allowed by USGBC LEED program.  This has been painted all around the exterior of our house in a couple of layers and does have a fairly nice consistency.  Here are some pictures of before and after shots.  To see all the methods and watch some “how to videos” please check out the company website. The site even goes into detail with how to treat joints when using Enershield. http://www.wallsystems.basf.com/en/enershield/Pages/default.aspx

Solar Power in the AIR!!!

Something exciting flew into the Midwest and it has to do with what we love most: Solar Power!!! An airplane named Solar Impulse made a stop in Saint Louis.  This is a solar powered airplane that made a grand tour of America in an attempt to circle the globe. It made a pit stop in Saint Louis and the plane was in lay over for a few days in early June to allow people to view it. It’s the first solar plane to fly day and night. For the U.S trip it flew more than 3500 miles. This is a Swiss made plane and with a 208 feet wingspan, it appears to look like a big glider. There are about 12,000 solar cells on this thing to power four electric motors. These motors will in turn drive the propellers. The engines will collectively create 40 horsepower and the plane requires 2,000 feet of runway to take off with. It will lift off the ground at 22mph.  With all of the lithium batteries included and the carbon fiber materials too, the plane weighs only 3,500 pounds.  Unfortunately, it mostly maintains a 40 mph speed but I say because of the fact this thing can fly at night, clean technology truly is reliable! That’s ok about speed because with the way technology makes leaps and bounds hopefully one day that Boeing 747 © you board for flight will have no need for fuel expect the clean energy from the sun. Sustainable technologies need to be encouraged so be sure to check this plane out on their website and continue to push for innovation!
