Energy Department Announces 6 Projects To Develop Energy-Saving Windows, Roofs, And Heating And Cooling Equipment

Friday, December 21, 2012

As part of the Energy Department’s efforts to help homeowners and businesses save money by saving energy, the Department announced today a $9 million investment in leading-edge building envelope technologies, including high-efficiency, high-performance windows, roofs and heating and cooling equipment. As winter temperatures set in for much of the United States, the Energy Department this week is also highlighting easy ways consumers can lower their heating bills on" target="_blank">

“A typical American family spends nearly $2,000 per year on their home energy bills, and much of that money is wasted on air leaks and drafts in our homes’ roofs, attics and walls. By bringing new, affordable energy efficient products to the market, we can help families save money by saving energy, while strengthening U.S. manufacturing leadership in technologies that are increasingly in demand worldwide,” said Energy Secretary Steven Chu.

This new investment supports six advanced manufacturing projects in California, Connecticut, Idaho, Maryland, Missouri and Tennessee that advance whole home energy performance. This includes:

· about $6.5 million in four projects to develop highly-efficient, cost-effective heating, ventilation and air conditioning (HVAC) systems; and

· about $3 million to two projects that focus on building envelope materials.

For example, St. Louis, Mo.-based Unico will receive $2 million to develop a cold climate heat pump with a variable speed compressor that will maintain capacity and efficiency even at very low temperatures. The University of Idaho will design and demonstrate a roof sandwich panel that uses foam material to increase building thermal efficiency and helps reduce construction costs by 25 percent. Lawrence Berkeley National Laboratory will develop and test highly insulated, easy-to-install windows that use automated shading that can capture or repel heat depending on the season.

While U.S. energy use per capita was fairly consistent from 1990 to 2007, building improvements in efficiency for space heating and air conditioning have helped achieve a reduction in the last five years. Nearly 60 percent of homes now feature energy-efficient, multi-pane windows – up from 36 percent in 1993. About 40 million households have used caulking or weather-stripping to seal air leaks and drafts and 26 million have added insulation. The U.S. Energy Information Administration expects that energy use per capita will continue to fall by an additional 15 percent through 2040.

Additional improvements are needed. In a typical residential or commercial building, about 42 percent of energy is lost through doors, roofs, attics, walls, floors and foundations – known collectively as the building envelope. In the winter months, windows can account for 10 to 25 percent of a home’s utility bill through heat loss. The projects announced today will help bring new, affordable technologies to market that address these opportunities for improved building performance and cost savings.

Literacy Is Critical

Government spending is often portrayed as a freight train "quickly running out of track." And there is some truth to that statement. There is not an endless supply of money to fund every good idea that comes along, and we must acknowledge that problem. Fiscal responsibility is a must.  That is why spending on priority issues like public education is important. You can spend ... (click for more)

Roy Exum: Prayer Over Despair

As a strong proponent of early voting, I joined hundreds at the Hamilton County Election Commission headquarters on Amnicola Highway yesterday to exercise what I consider one of our greatest freedoms – “for the people, by the people.” Candidly, I have never been as upset or as disappointed over my choices for President in my life. Locally I am fine with our candidates but to pick ... (click for more)
