Eclipsis System--Sun Shade Arrival

The Sun Shade just arrived to the LUMENHAUS construction site (National Building Museum) today!
The Eclipsis System is an advanced building façade comprising two layers: a metal shutter shade and a translucent insulating panel. The shutter shade slides along the north and south façades, providing protection from direct sunlight while simultaneously allowing for indirect, natural lighting, views to the exterior and privacy to those inside. The sliding insulating panel is a translucent polycarbonate panel filled with aerogel. Aerogel is a super lightweight, highly insulating translucent material that provides insulation equivalent to a typical sold wall during harsh weather conditions without blocking natural light.

Virginia Tech & the Solar Decathlon: What About Us?

by Kristin Underwood, Sacramento, CA  on 09.10.09

Hot on the heels of the article about Penn State using Ed Begley Jr to earn them brownie points in the Solar DecathlonViginia Tech quickly shot back a post. 'What about us?, they said, we're in the National Building Museum in Washington, DC right now. Doesn't that get us any press and kudos for the competition?'

Virginia Tech's entry to the Solar Decathlon is currently on display and open to the public until the competition begins this October. The solar house, titled LUMENHAUS, an 800 square foot zero-energy home, will be on display but students and faculty working on the project will also be making adjustments during this last month - more like a living artwork, if you will. The house is designed to dress itself and you for the seasons and is smart enough to know when to add more light, less light, more heat or less heat. If you can't make it to DC, you can visit the house virtually on theirLUMENHAUS website, which includes pictures, videos and even footage of people living in the house.

The museum will also host an event September 10 at 6:30pm to talk about sustainable design and solar energy. Leaders from the Solar Decathlon, NREL and other green building gurus will be on hand to answer questions and talk about the future of these cutting-edge technologies.

The Solar Decathlon challenges schools to design a house that can produce enough hot water and electricity to run all of the functions of a normal home and the team at the end of the week with the most points wins. In 2005, the Virginia Tech home won fourth overall and first place in best architecture, livability, day lighting and electric lighting. The Virginia Tech team is also one of only two universities invited to attend the Solar Decathlon Europe in Spain, June 2010. :Virginia Tech News :LUMENHAUS

LUMENHAUS on Re-Nest

Lumenhaus: Green Home Inspired by Mies

Lumenhaus is Virginia Tech’s 2009 entry to the US Solar Decathlon competition, an educational project of the U.S. Department of Energy supported by DOE's National Renewable Energy Laboratory. This green house was inspired by the Farnsworth House by Mies Van Der Rohe. It features glass walls facing the north and south to maximize daylight, and the fully automated Eclipsis System of independent sliding layers filters light in beautiful, flowing patterns throughout the day...

 Lumenhaus is a zero-energy home completely powered by the sun. Other sustainable features include the use of passive energy systems, a rainwater and greywater recycling systems, radiant heating and building materials that are from renewable and/or recyclable sources. The modular design means multiple units can be connected to create a space tailored to the needs of the owners, and the rectangular open design has a small footprint but still creates a perception of greater space. The Lumenhaus represents almost two years of labor by the design team at Virginia Tech.

You can read more about the Lumenhaus online or even fan it on Facebook. If you want to see the Lumenhaus in person, you can check out the unique Eclipsis panels at the Taubman Museum in Roanoke Virginia through August 16, or wait until October when DOE will erect a "solar village" on the National Mall and allow the public to tour the houses- we'll definitely be there for the big unveiling!

Adios Blacksburg, Hello Washington, DC


It took all night driving but LUMENHAUS finally made it from Blacksburg to Washington, DC.

Here's a picture of the innovative transportation system that allows LUMENHAUS to be constructed and sent to any location.

LUMENHAUS loves MODEA

We cannot thank local Blacksburg media company, Modea, enough for their in-kind services! Here's the extended Communication Team responsible for the LUMENHAUS website.

LUMENHAUS off to Washington, DC

Tech solar house off to D.C.
Monday, August 31, 2009; 10:55 PM
A smart phone can now control a smart house.

Lumenhaus, Virginia Tech's third solar decathlon entry, departs for Washington, D.C., tonight chock full of new technology and applications.

Project coordinator Joseph Wheeler said a new feature of this entry allows the user of the house to monitor energy usage.

"We have a way, using technology, to allow the user of a house to view where the energy is going," Wheeler said.

The house's energy can be viewed and controlled on an Apple iPhone.

"With the iPhone and Siemens control system, you have access to everything going on in the house," Wheeler said.

Lumenhaus is Tech's entry into the Solar Decathlon sponsored by the Department of Energy.

Faculty adviser Robert Dunay, director of Tech's Center for Design Research, said the project has already helped educate the general population about energy consumption.

"I think it has already proven to be successful because the DOE is trying to get the public more aware of daily use of energy," Dunay said.

The competition, which Tech will participate in from Oct. 8-18, occurs every two years. It is held on the National Mall in Washington, D.C.

"They do that every other year now, and it's one of the main instruments the DOE is using to alert the public to different areas of energy," Dunay said. "The focus of this competition is photovoltaic energy," which is the use of solar cells.

However, Lumenhaus will first participate in a month-long exhibition on the lawn of the National Building Museum.

The house will arrive early Wednesday morning, and Wheeler hopes to have it fully assembled by noon. He credits the minimal assembly time to the method of transportation.

"We came up with an innovative transportation system in 2005 that would allow us to get the house to the Mall in one piece," Wheeler said.

He said the month-long exhibition is a key time to improve Lumenhaus' chances of winning the October competition.

"One month is critical for testing that is going to give Virginia Tech an edge that no other team is going to have," Wheeler said.

Dunay said the experience of two previous entries in the competition has also added to the project.

"Each time, the degree of sophistication goes up exponentially," Dunay said. "This house is quite more advanced than our two previous competition entries."

The competition requires students to operate as if they were living in the house.

"The students have to run the house the way a family would run it," Dunay said. "Everything that is done in a normal house is simulated or done in the competition while they're on the Mall."

Students will not sleep in the house overnight, as the Mall does not allow it.

Dunay said 14 core students will accompany the house to Washington, D.C. He said the number of total contributing students is "probably in the hundreds."

One new part of the competition measures how much energy the houses can contribute to the local power system.

"This is the first time the houses are grid-tied," Dunay said. "Now, any extra energy we dump into the grid we get points. It's part of the energy balance competition, which is one of the 10 competitions in the solar decathlon."

The house accomplishes the energy surplus by monitoring and adjusting to weather and weather forecasts.

Lumenhaus will also compete in an international competition known as Solar Decathalon Europe. It will be held in Madrid, Spain, in June 2010. The house will be transported by boat.

The project has received corporate support from ConocoPhillips and Siemens. It is also partially funded by cash donations.

ConocoPhillips offered support after viewing Tech's 2005 solar decathlon entry. Wheeler said the evolution of the house was aided by the success of previous entries into the competition.

"When we start a new project, we don't start over," Wheeler said. "We start where we left off."

Virginia Tech solar house to hold community open house Sunday, Aug. 30

By Heather Riley Chadwick

BLACKSBURG, Va., August 27, 2009 -- The Virginia Tech solar house will be open for tours on Sunday, Aug. 30 from 4-6 p.m. when faculty and students will be on hand to answer questions and describe the final stages of construction.

The house is currently located the parking lot of the Blacksburg Square shopping center on South Main Street in Blacksburg. The solar house, which the team designed and is working to finish constructing, will compete in U.S. Department of Energy Solar Decathlon in October.

The Virginia Tech solar house, which is named LUMENHAUS, epitomizes a “whole building design” construction approach, in which all the home’s components and systems have been designed to work together to maximize user comfort with environmental protection. LUMENHAUS uses technology optimally to make the owner’s life simpler, more energy efficient and less expensive.

On the cutting edge of responsive architecture, LUMENHAUS can operate completely self sufficiently, responding to environmental changes automatically to balance energy efficiency with user comfort. It is a zero-energy home that is completely powered by the sun. Sustainable features of the house include the use of passive energy systems, radiant heating and building materials that are from renewable and/or recyclable sources.

On Sept. 1, the house will move to the National Building Museum in Washington D.C., where it will be on exhibition until it relocates to the National Mall in early October for the Solar Decathlon. In June 2010, the house will be shipped to Madrid, Spain, where it will be one of only two United States entries invited to the Solar Decathlon Europe competition.

Lumenhaus – Virginia Tech’s Smart Solar House

by Bridgette Meinhold, 08/21/09

lumenhaus, virginia tech, solar decathlon, solar decathlon 2009, smart house, prefab, modular, solar system, geothermal heat pump, eclipsis system

We’re getting excited about this year’s Solar Decathlon and love Virginia Tech’s zero-energy, smart house.Lumenhaus — which is a combination of Lumen, meaning power of light, and Haus, which is a reference to theBauhaus architectural movement — is a high-tech home that will be sure to garner a lot of attention at the upcoming competition. In fact it’s only one of two US teams to be accepted into the Solar Decathlon Europe, where it will compete against teams from around the world.

lumenhaus, virginia tech, solar decathlon, solar decathlon 2009, smart house, prefab, modular, solar system, geothermal heat pump, eclipsis system

Lumenhaus is an 800-square-foot, 1-bedroom residence with an open floor plan that extends to the outside decks when the Eclipsis System is open. The Eclipsis System is Virginia Tech’s advanced shading system that automatically opens and closes in accordance with the current weather conditions. The Eclipsis System is comprised of two layers: a metal shutter shade and a translucent insulating panel, which is a translucent polycarbonate panel filled with aerogel. Aerogel is a super lightweight, highly insulating translucent material that provides insulation equivalent to a typical sold wall during harsh weather conditions without blocking natural light.

During good weather, the semi-transparent screens open to let in natural daylight and sliding doors extend the living space out onto the deck. During bad weather, the screens slide shut to shelter the house from cold winds, rain or snow. The home’s smart system gathers information from its rooftop weather station to automatically control the screens, rooftop solar system, heating and cooling and lighting.

The roof  is a double efficient solar system, which collects enough energy to make the house a net zero house. The solar panels are bifacial, meaning they use both sides to increase energy output by up to 15 percent, and they system tilts up to the optimum angle. A geothermal heat pump efficiently heats and cools the home. Orientation and design allows for a naturally day-lit home, reducing the need for artificial lighting. The home and energy systems  can also be controlled via smart phone, so if you are away and forgot to turn off the lights, or computer or god forbid the oven, you can remotely turn them off.

As one would expect for a Solar Decathlon entry, the home includes many more green design features, likegraywater recycling, rainwater collection, radiant floors, LED lighting, home management system, and use of sustainable materials. While the prototype has cost around $350,000 provided by corporate sponsors, future models should cost less. The prefabricated and modular design of the house allow for efficiency of construction and variation in design that makes it quite a stellar example of home building.  Good luck at the competition, Virginia Tech!

The American Ceramic Society & LUMENHAUS

Virginia Tech aims for the sky to win Solar Decathlon

Lumenhaus is Virginia Tech’s zero-energy home that can be completely powered by the sun and geothermal energy. Other sustainable features include the use of passive energy systems, radiant heating and building materials made from renewable and/or recyclable sources.

The College of Architecture and Urban Studies is entering the house in the U.S. Department of Energy’sSolar Decathlon 2009.

The house will be displayed outside the National Building Museum in Washington, D.C. for most of September. In October, Lumenhaus will be on display at the National Mall along with other entrants in the Solar Decathlon. And, Virginia Tech is one of only two U.S. universities invited to compete in the first Solar Decathlon Europe, which will take place in Madrid in June 2010.

A powerful array of photovoltaic panels provides carbon-neutral energy to the house. The PVs, arranged in a single array that covers the roof, are built into the house during construction. The panels are bifacial, meaning they use both sides to increase energy output by up to 15 percent. Using an electric actuator, the entire PV array can be tilted to the optimal angle for each season (from zero degrees to a 17-degree angle in summer and to a 35-degree angle in winter).

The energy collected during the day will be radiated back out at night through a low-energy, long-lasting LED lighting system.

Lumehaus is not only energy-efficient; it is water-efficient, too. The roof is sloped to collect rainwater that is filtered for potable use in the house, while used household greywater – from the shower, bathroom sink and clothes washer - goes through a series of bio-filters in the surrounding landscape where it is cleaned for non-potable use.

The solar house is moved

Lumenhaus: Virginia Tech's 2009 U.S. Solar Decathlon team last week moved its 800-square-foot entry, known as LUMENHAUS, from the Research + Demonstration Facility on Plantation Road to the Blacksburg Square shopping center on South Main Street.

LUMENHAUS is a zero-energy home that can be completely powered by the sun. Other sustainable features include the use of passive energy systems, radiant heating, and building materials that are from renewable and/or recyclable sources.

Moving LUMENHAUS to Blacksburg Square will allow the Solar Decathlon team to attach solar panels to the roof and put other finishing touches on it before its next stop, Washington D.C.

The house will be displayed outside the National Building Museum for most of September. In October, LUMENHAUS will be on the National Mall along with other entrants in the U.S. Department of Energy Solar Decathlon 2009.

VT Annual Fund Article

Unlimited Opportunities: The Virginia Tech Annual Fund supports extraordinary student experiences

Alden Haley, Corey McCalla, Kevin Smith, and Danny Slover (left to right) are among the dozens of Virginia Tech students getting valuable experience as part of the Solar Decathlon team.

By Albert Raboteau

Students in Virginia Tech's nationally renowned architecture program learn how to design beautiful structures during their five-year course of study. Actually getting their designs built is something that usually does not happen until they are out working in the field.

But for students like Alden Haley and Corey McCalla that is not the case. They are among the dozens of Hokies -- from a variety of programs -- who are getting real-world experience in their fields of study by participating in theU.S. Department of Energy Solar Decathlon 2009.

With help from faculty advisers, as well as considerable donor support, the students on Virginia Tech’s Solar Decathlon team are building an 800-square-foot home to showcase new possibilities for environmentally friendly design.

Their structure -- which is named LUMENHAUS in homage to the Bauhaus design movement that influenced its look -- will not only have solar panels on the roof, but a computerized system to maximize energy efficiency and user comfort.

"In school it's pretty uncommon to actually have built a house," says Haley, an Ashland, Va., native who, like McCalla, is heading into his fifth year of the architecture program. "It's a handful of people at most, so this is really special."

McCalla, who is from Rockville, Va., says the Solar House is "definitely the most memorable project and one of the most memorable experiences I've had at Virginia Tech, and in my whole education."

Robert Dunay, the T.A. Carter Professor in Architecture, says that is likely to be the case for lots of students.

"This is probably one of the best educational experiences that they get -- to see the transition between the abstraction of their drawings and calculations and the performance of the actual construction," says Dunay, a faculty adviser to the Solar House team.

Architecture students are not the only ones benefiting from the Solar House project. Kevin Smith of Fairfax, Va., says his experience on the project "really ties in with what I’m going to be doing in my career."

He graduated in May 2009 with a bachelor's in mechanical engineering and will soon start working on energy-use analysis for Southland Industries, a mechanical engineering, construction and service firm that operates nationwide and specializes in government buildings.

Shortly before Palisade, Colo., native Danny Slover graduated with a bachelor's in electrical engineering in May 2009, he said: "I had a job interview last week where I talked about [the project]. It shows your ability to work as a team."

Assistant Professor of Architecture Joe Wheeler, another adviser on the project, says students from his college on the Solar House team learn how to work with suppliers, contractors, engineers, and even marketers, which is something they will have to be able to do well if they ever want to have their own architecture firm.

"The ability to work across disciplines is something that they usually don't see until they are out in the profession, so that is kind of an eye opener for them, to see how a real project really works," Wheeler says.

Christine Burke, of Manassas, Va., is on pace to graduate from Pamplin College of Business with a bachelor's in marketing in December 2009. For students like her, the project is a chance for hands-on experience promoting LUMENHAUS. Students are working in creative ways to publicize the house online, including social marketing through Twitter and Facebook.

"I'm interested in brand management, so it's great working on this project because we’ve actually created a brand," Burke says.

Coming up with a communication plan is part of the overall Solar Decathlon completion, which takes place on the National Mall in Washington, D.C.

Virginia Tech is fielding one of 20 student teams in the Solar Decathlon, which is the most recent in a series of such contests sponsored by the U.S. Department of Energy to promote energy efficient construction. Each team will display its entry on the National Mall in Washington, D.C., for three weeks in October 2009.

Virginia Tech has a record of Solar Decathlon success. The university's 2005 entry placed fourth overall, but won first place in four categories: best livability, best architecture, best day lighting, and best electric lighting. The 2005 entry also received the American Institute of Architects President's Award for Best House.

In 2010, the Solar Decathlon team will ship LUMENHAUS to Spain to compete in aEuropean version of the contest. Virginia Tech is one of two U.S. universities invited to participate in that contest.

"Extraordinary opportunities such as competing in the United States' as well as the European Union's solar decathlons come about through private philanthropy," says Jack Davis, dean of Virginia Tech's College of Architecture and Urban Studies. "The annual fund is an important component of the funding portfolio for this project in particular, and the college as a whole. Donors enrich our resources to be able to execute important environmental and energy based research at both the undergraduate and graduate level."
