MUSIC I think one of the unique parts of the design is the fact that we created two totally prefabricated units that could be shipped quickly and assembled quickly on site. The two units fit together on one truck and with the crane on site can be dropped in a matter of six hours. I feel like that is pretty unique design component. There was a set of tornadoes that came through just north of Champagne Illinois so we wanted to come up with a design that could really cater to those individuals. We came up with a house that could be premanufactured in.
A modular home environment so they can be both quick and affordable. And once it gets on site we wanted to really reduce the amount of skilled labor that had to be involved. So you see the house is totally constructed the envelope is totally enclosed except for one seam that needs to be sealed. The solar panels on the roof are also fully wired and installed they just have to fold them flat during shipping so it's very minimal time to get those up and running. So, the house really is designed to cater to rapid response.
MUSIC Regarding specific technologies, you'll see some new solar panel usage. They provide both shade and solar power and it's a unique application of building integrated photovoltaics. And also on the interior we have a new, it's called a Serve System for our HVAC, circulating energy recovery ventilator. And it's a very efficient system that is all indoors as far as a condenser and an evaporator, which allows us to minimize the openings in our envelope. MUSIC Thank you everyone for their hard work, I mean, so many people put really tons of.

The University of Illinois' Rehome offers a new solution for disaster relief housing. This twomodule home is designed to be quickly transported and easily assembled in the event of a natural disaster. The Rehome also serves as more than a shelter it enables individual and community recovery through a socially and environmentally aware response. The two modules are prefabricated at a modular home manufacturer using standard 2x4 construction with spray foam insulation. Additional insulation is then added to the exterior of the walls using rigid foam panels. This tactic provides a highly insulated, airtight structure that cuts down on the amount of.
Energy needed to condition the home. Cedar siding is used as a rain screen to complete the exterior walls. There are two large deck spaces and a ramp constructed from reclaimed wood. The deck spaces extend the livable area of the home and encourage community and family interaction. Covering the deck are easily assembled shading canopies that define the area and shade the windows along the western and southern faade. A 7.2 kW photovoltaic system comprised of integrated photovoltaic and shading panels along The front faade and 24 adjustable modules on the roof, generates enough power to operate the Rehome. The panels can be shipped flat.
On the roof and adjusted to the correct angle on site. The landscaping surrounding the deck space provides privacy and edible vegetation that can easily be grown locally in the Midwest. The front door of the Rehome leads to a main living area of the house. Here, there is seating available for large groups, with two couches, eight slim folding chairs, and bar stools. The living room opens up to the kitchen containing highly efficient appliances, including an induction stovetop and a low flow faucet.

In recent years the frequency and intensity of natural disasters has grown significantly. Responding to these situations through design, planning, and construction must be reconsidered. When a disaster strikes, temporary housing should serve both as a shelter, and as a move to individual and community recovery. The University of Illinois' Rehome provides a socially and environmentally aware response. The Rehome utilizes a quick deployment and assembly strategy. The house is prefabricated and is easily transported. It can be ready and shipped when disaster strikes. When needed, the two modules are shipped on a single truck.
Then, they are connected and sealed at the site, providing an enclosed shelter only hours after delivery. Prefabricated shading canopies and decks are quickly assembled. Vegetation is immediately implemented at the site as well. The twounit design maximizes the connection between interior and exterior space, allowing for flexibility in how the space is used. The open floor plan encourages interaction between the public areas of the home, giving a variety of spaces for different activities. Flex space off of the main living room can be used as an office or second bedroom to.
Accommodate a variety of users. The variety and flexibility of livable areas in the Rehome is also demonstrated through two outdoors patios. A public deck off the kitchen and a private patio off the master bedroom offer additional areas to relax and entertain. The Rehome also incorporates a variety of sustainable design practices. The home is in modules, to the highest construction standards. This ensures an airtight structure and efficient construction. The Re home has super insulated walls with an R45 value and a super insulated floor and ceiling with R60 values. These walls, along with triple.
Pane, low E, argon filled windows greatly decreases the energy demand of the home. The photovoltaic array is preinstalled on the roof of the Rehome, allowing the panels to be shipped flat and adjusted to optimal orientation on site. The PV panels benefit from reflected light off the flat, white EPDM roof. Additional PV panels are integrated in the south shading canopy, providing more energy and adding visual interest. Resources are also conserved in the Rehome through a roof rainwater catchment and storage system, this can be used to water vegetation. The Rehome provides a flexible solution.

Rehome was designed to be a netzero energy usage home. It uses passive energy saving strategies, integrated with highly efficient and smart active systems. 9 teams of Illinois engineering students worked with the architecture team to make this possible. With walls rated R45 and the roof and floor both rated R60, the Rehome is extremely well insulated. The layout and orientation of the Rehome are core components of the passive design concept. In order to maximize solar gains, windows are placed mostly on the south faade. Shading devices are utilized to control daylight. ReHome has been engineered as a smart home.
It is outfitted with over 100 sensors and dozens of embedded microcontrollers. This allows control and monitoring of everything from the power consumption of a single device plugged into an outlet, to water usage and grey water availability, to temperature, humidity and carbon dioxide levels. A powerful controls system was required. This would give information and control to the user, in a single, unified space. The Engineering team developed the recontrol user interface. This interface uses web technologies and the convenient iPad touchscreen. A database logs all data displayed on the interface. The recontrol portal gives.
The user useful ataglance data such as indoor and outdoor temperatures, a graph of overall home power consumption vs. production, and has links to other pages, which control various subsystems. The heating, ventilating, and air conditioning system utilized in the ReHome is a Conditioning Energy Recovery Ventilator or CERV. The CERV is an airsource heat pump specifically designed for wellinsulated, airtight homes. The recontrol HVAC page gives the user access to the CERV controls and status information. The Rehome has been outfitted with a photovoltaic array that provides 6.7 kilowatts during peak sun. The array utilizes.
18.5 percent efficient crystalline panels. The panels collapse flat for transport. The solar monitoring page provides a user with valuable power production and consumption information. ReHome is equipped with a fully automated, power conserving, ledbased lighting system, and a power monitoring system capable of recording the usage of each device in the home. Each region of the ReHome floor plan may be clicked to retrieve usage information specific to that area of the home. Single devices are represented by globes on the floor plan. A lit globe shows that that device is consuming power. A user can select from specific.
Solar Decathlon Open House September 10, 2009
A lot of the electrical engineers have been intricately involved in the design and installation of all the systems that have gone in the house, and it's given them a lot of exposure, a lot of opportunity to go beyond the classroom and see how they can put their knowledge to real world use. It's my second solar decathlon, I worked on the 2007, now we've got the 2009 house going here and I have been working predominately on the photovoltaic system. So we have 40 solar panels, they're sun power, I think they're rated at 225 watts, giving us a total power rating of 9.1 kilowatts.
We're very happy that we have a great tied system, and the idea for that is that you're pumping power back into the grid the utility company buys it from you, so you're able to make money on the energy you produce that way. I've been working on a lot of the control and monitoring system for the house, and I've also done a little work on the electrical system with Charlie. So behind me are two invertors that take the DC power from the panels and turn them into AC so we can hook.
Them up to the grid. The DC comes in from our panels and into these invertors and out of the invertors into our breakers where it goes to the grid to be grid connected. Behind the breaker we have current sensors on every single line coming in to each breaker. We have this board that I designed that takes the current sensors in and changes them into a voltage so that we can monitor them with thisback that I have taped on the back of the board. We also have the ability to control a lot.
Of the outlets and the lights from a touch screen monitor in the wall. So I think that having the ability to monitor the power in every circuit is going to be a really nice feature that people in their houses could find handy to help reduce their power consumption. I worked on a number of things, including the simulation of the power from our solar panels and the home automation system which consists of theswitches and outlets controlled by an interface on a touch screen. So a lot of sleepless nights with a lot of students, but I think they come out as better.
The Future of Solar Power
Well I work in power electronics, alternative energy and energy conversion so a lot of the work we do relates to hybrid and electric vehicles, solar energy conversion, wind processing and integration of all of these things into the electricity grid. Lately we've been working on modular converters for solar power so that one can basically take a photovoltaic panel and integrate the electronics right into it, and plug the thing in and have it be done, so its delivering energy to the grid. So this one for example, although its not typical, it's one that I kind of scrounged.
As a little test piece, is one of the early prototypes of our solar energy converter. This in its next generation or two form will become an actual commercial product that gets integrated with solar panels and becomes really I think the easiest way to do conversion of solar energy. I'm very hopeful that one or two years from now we're going to see frankly an explosion in the use of solar energy because of some of the things we've been doing over many years. A lot of things we're doing, I think, will become the next generation's solution.
The Future of Solar Energy is TINY Technology!
The future is huge for tiny technology. Miniaturization is, perhaps ironically, a huge deal. I mean, without it we wouldn't have had the personal computer revolution and we wouldn't have this world we live in now, where we have smartphones and tablets and other devices just as powerful as a computer, that can fit in the palm of your hand. But even these gadgets are gargantuan compared to nanotechnology! See, a nanometer is just one billionth of a meter. And that's kind of hard to imagine, so let me put it to you this way.
Your typical sheet of paper is about one hundred thousand nanometers thick. And at this scale, individual elements are so small you can't even see them with a light microscope. Now as we learn more about how materials behave on the nanoscale, we have more potential applications to use that knowledge practically. I'm talking about how nanotech could help solar panel technology. And fortunately, at a recent meeting of the American Association for the Advancement of Science, or AAAS, they had a panel on just this very subject. Now if you know anything about solar panels you know they have some drawbacks. For example,.
Efficiency they max out at around twenty percent in the field under ideal conditions. They're also rigid, so you can't just put them anywhere you like. And they tend to be expensive because manufacturing them is complicated. But scientists hope that nanotechnology can help address all three of these challenges. Now with efficiency they're looking to nature specifically, moth eyes. You see, moths have these little tiny structures in their eyes that help reflect light back into the eye and it does two things it lets them see better in the dark, and it cuts down.
On reflection so predators can't spot them as easily. With solar panels it could actually make them more efficient by reflecting more of the sun's light into the panel so you lose less in reflection. And when we're talking about flexibility, well nanomaterials are really, really small, and there is the potential to create solar panels that are just a few sheets of molecules thick. They could be as flexible as a sheet of paper, and with that kind of flexibility you could put those pretty much anywhere you wanted to.
And as for price, well, that's the big one. And in the short term I don't think it's going to turn around. But scientists are cautiously optimistic that nanotechnology will let us use new processes, like printing solar panels directly onto a substrate using just a specialized printer. That would actually be less complicated and expensive than traditional manufacturing methods. Now at that meeting of the AAAS, a Dr. Wolfgang Porod gave a talk about Nanoantenna Thermocouples for Energy Harvesting. Which I admit sounds like technobabble straight out of a Star Trek episode.
But it's actually fairly simple once you break it down. A nanoantenna is just an antenna on the nanoscale. These resonate with longwave infrared radiation. And a thermocouple Well that's a component of circuitry that generates a voltage when one part of the thermocouple is a different temperature than other part. So you pair these two together and the antenna generates heat and the thermocouple generates voltage. It could actually help increase the efficiency of solar panels. Now like I said, nanotechnology is a young science and it has lots of different applications.
Across many disciplines. And I'm really excited how such a small technology could have such a huge impact. That leads me to this week's question. When I say the word nanotechnology what do you imagine What does that word mean to you Let us know in the comments below. Then, do me a nanosized favor and share this tutorial with your friends.
