Photodetachment neutralizer development: Laser window design study: Volume 1, Summary: Final report

Description: Photodetachment neutralization (PDN) has been proposed as a major improvement to the gas cell neutralization utilized on current neutral beam heating systems for magnetic containment fusion devices. This PDN system will use a Chemical Oxygen Iodine Laser (COIL) to produce a light beam with photons of a near optimal wavelength which can be reflected back and forth across the path of the ion beam to create the necessary high density light ''cloud'' required for the photodetachment process. In a f… more

Analysis of 2009 International Energy Conservation Code Requirements for Residential Buildings in Kansas City, Missouri

Description: The 2009 International Energy Conservation Code (IECC) contains several major improvements in energy efficiency over the 2006 IECC. The notable changes are: (1) Improved duct sealing verified by testing the duct system; (2) Increased duct insulation; (3) Improvement of window U-factors from 0.40 to 0.35; and (4) Efficient lighting requirements. An analysis of these changes resulted in estimated annual energy cost savings of about $145 a year for an average new house. Construction cost increases… more

Highly Insulating Windows for Improved Energy Efficiency and Reliability in Fenestration Applications

Description: EverSealed Windows, Inc. (ESW) agreed in early 2006, prior to the contract award, to add three additional deliverables to the Project (new Milestones 30, 31 and 32), and have the results of these three deliverables form the basis of the go/no-go decision for proceeding from BP1 to BP2. ESW completed all three milestones and the DOE agreed in November 2006 to continue the Project. ESW subsequently initiated work on BP2 and its two milestones. These were to (1) Assemble and test glass-to-metal bo… more

Highly Insulating Windows with a U-value less than 0.6 W/m2K

Description: U.S. households rely primarily on three sources of energy: natural gas, electricity, and fuel oil. In the past several decades, electricity consumption by households has grown dramatically, and a significant portion of electricity used in homes is for lighting. Lighting includes both indoor and outdoor lighting and is found in virtually every household in the United States. In 2001, according to the US Energy Information Administration, lighting accounted for 101 billion kWh (8.8 percent) of U.… more

Capturing the Daylight Dividend

Description: Capturing the Daylight Dividend conducted activities to build market demand for daylight as a means of improving indoor environmental quality, overcoming technological barriers to effective daylighting, and informing and assisting state and regional market transformation and resource acquisition program implementation efforts. The program clarified the benefits of daylight by examining whole building systems energy interactions between windows, lighting, heating, and air conditioning in daylit … more

Fenestration System Performance Research, Testing, and Evaluation

Description: The US DOE was and is instrumental to NFRC's beginning and its continued success. The 2005 to 2009 funding enables NFRC to continue expanding and create new, improved ratings procedures. Research funded by the US DOE enables increased fenestration energy rating accuracy. International harmonization efforts supported by the US DOE allow the US to be the global leader in fenestration energy ratings. Many other governments are working with the NFRC to share its experience and knowledge toward deve… more

Evaluation of integrated wall systems incorporating electrochromic windows [Final report]

Description: Billions of dollars are spent annually in the U.S. on energy lost through the use of inefficient windows. Even wall systems with advanced static glazings and moveable shading devices are not optimal because they can't effectively respond to changing solar conditions. Electrochromic (EC) smart windows can dynamically control the amount of solar light and heat entering a building. The energy saving performance of fully dynamic wall systems containing EC windows was compared with that of static sy… more

Will Duct Tape and Plastic Really Work? Issues Related to Expedient Shelter-In-Place

Description: Expedient sheltering involves the use of common materials to enhance the safety of a room inside a building against the impacts of a chemical plume. The central premise behind taping and sealing with duct tape and plastic is to reduce airflow into a room. This paper reviews issues associated with the use of expedient sheltering materials and the effectiveness of this strategy. Expedient sheltering provides additional protection to people sheltering in place beyond that provided by the house and… more

Energy Efficient Electrochromic Windows Incorporating Ionic Liquids

Description: One approach to increasing the energy efficiency of windows is to control the amount of solar radiation transmitted through a window by using electrochromic technology. What is unique about this project is that the electrochromic is based on the reduction/oxidation reactions of cathodic and anodic organic semi-conducting polymers using room temperature ionic liquids as ion transport electrolytes. It is believed that these types of coatings would be a lower cost alternative to traditional all in… more

Switchable window modeling. Task 12: Building energy analysis and design tools for solar applications, Subtask A.1: High-performance glazing

Description: This document presents the work conducted as part of Subtask A.1, High-Performance Glazing, of Task 12 of the IEA Solar Heating and Cooling Program. At the start of the task, the participants agreed that chromogenic technology (switchable glazing) held considerable promise, and that algorithms to accurately model their dynamic behavior were needed. The purpose of this subtask was to develop algorithms that could be incorporated into building energy analysis programs for predicting the thermal a… more

Final report for confinement vessel analysis: Task 1, Correlation of new vessel data with finite element results

Description: Los Alamos performed tests of a modified confinement vessel in November 1992 to gain a better understanding of the response of the confinement vessel. The first test was meant to duplicate, with additional instrumentation, tests done previously for correlation with analysis. Task 1 of Subcontract Number 9-XH3-0607K-1 was the correlation of this new vessel test data with the results of finite element analyses. The authors also examined the data for the other test, which was for optical port deve… more

The energy-savings potential of electrochromic windows in the UScommercial buildings sector

Description: Switchable electrochromic (EC) windows have been projected to significantly reduce the energy use of buildings nationwide. This study quantifies the potential impact of electrochromic windows on US primary energy use in the commercial building sector and also provides a broader database of energy use and peak demand savings for perimeter zones than that given in previous LBNL simulation studies. The DOE-2.1E building simulation program was used to predict the annual energy use of a three-story … more
