Norwich University,Norwich University in Northfield will host a party on Friday, July 26, from 3-6 pm to celebrate the completion of the student designed and built solar house before its cross-country trek for the 2013 Solar Decathlon. The party will be at Disney Field, where the house is currently located. Norwich is one of just 20 collegiate teams chosen by the US Department of Energy to take part in the competition in which students design, build and operate a solar powered house that is cost effective, energy efficient and attractive. The winner of the competition will be the team that best blends affordability, consumer appeal and design excellence with optimal energy production and maximum efficiency. The competition will take place in Irvine, Calif, from October 3-13. The team of students who conceived, designed and constructed the house will provide tours during the celebration. There will be free ice cream and live music by rock band, Black Cat Bone. The event, ‘So Long Solar House,’is free and open to the public. About DT90 Called Delta T-90 (DT90), Norwich’s house was designed to maintain an inside temperature of 70 degrees in a climate as low as -20 degrees F; a 90-degree differential. The design accounts for the roof of the house being covered with snow three months out of the year ‘a common Vermont occurrence. Norwich students built the DT90 to compete as the most efficient and beautiful solar-powered house, and to help solve a statewide problem of affordable housing. Designed to be manufactured as a 1,000-square-foot modular home, the DT90 house is affordable on an annual income of $36,000. Friday, July 26, is the last day to tour the house before it is broken down and packed up to make the trek across the country to the Orange County Great Park in Irvine, Calif., for the 2013 Solar Decathlon and Expo. Norwich students and faculty will spend the month of September in California, reassembling the house. During the October 3-13 competition, they will be providing tours and information to the public and judges.
