This report will explain the detailed steps we undertook during the improvement of the windows in the Penn State dorms. The objective of this project was to increase the efficiency of the windows to help cut back on heating and cooling cost by apply a coating to the windows and improving the seal to help keep heat in the building. Through collective brainstorming, our team analyzed the problems associated with the old windows. We decided which aspects needed improvement, which ones needed to be redesigned, and which ones could be left alone. Our team conducted a survey of potential customers and examined the data through various PCC, AHP charts, and TRIZ models. From the results of the survey and our team’s ideas, we felt the most important features that needed to be worked on were the sealing of the windows and the amount of energy and heat they can keep in. Each of these features needed to be redesigned in order to create a more effective and low cost design. We successfully accomplished our overall goal of creating a more efficient window by modifying key aspects of the window and frame. The following report outlines the research process and development that we undertook to improve the window in the dorms, and concludes with the finished model of our more efficient windows.

At the same time the film will significantly reduce the amount of heat lost through the window during cold winter months Dorm Window seal Traps heat inside building Window film Trap heat and reflect Heat in dorms Sunlight TRIZ EMS Models: shows the EMS model for the window system. The dorms are heated, and this heat escapes through the window seal, which is a problem with the current windows in the dorms because they have to use more energy to continue to keep the buildings heated. During the warmer months, the sunlight from outside hits the windows and can provide unwanted heat to the building. With the clear window film will save on average $30 per dorm room a year. With the film costing about $20, so the school will pay off the down payment for the film with in the first year. Just in my dorm hall alone, the school will save $4,800. This dorm hall is roughly 16 rooms a floor and has 10 floors. With their being 14 dorms total in East, the total annual saving will be about $62,700. With the window film’s life span of 15 years the school can expect to save more than $1,000,000. And a side bonus of the film is that it reduces UV rays by 99% which will help keep furniture from fading. Also it will reduce 675 lb CO 2 per room to help reduce the carbon foot print of each room; which comes out to be 11,340 tons CO 2 eliminated by all of the dorms in East over the 15 year lifespan.
