Rod-shaped PZT specimens were sintered with 1 w/o and 5 w/o PbO additives. ZrO/sub 2/ segregations were found in the 1% PbO specimen, and higher PbO segregations were found along the grain boundaries and at grain boundary with no ZrO/sub 2/ segregations in the 5% PbO specimen. On the basis of these microstructural observations and preliminary poling studies sintered thin disc specimens with a 3 w/o PbO additive were prepared for extensive poling studies. It was found that the breakdown limit of a specimen depends strongly on the porosity and the pore distribution. The best specimen (3 w/o PbO) could be poled at a field of 6 kV/mm, a temperature of 100/sup 0/C and a time of 10 minutes without breakdown. The planar coupling coefficient, K/sub p/, under these conditions was immediately after poling equal to 0.62. This value is the highest among the reported K/sub p/ values for pure PZT. Within the breakdown limit, K/sub p/ increases with increase of poling field, temperature and time in a regular manner so that K/sub p/ values for other conditions can be predicted. It was found that the specimen became unstable above 125/sup 0/C even when poled at low fields for shortmore » times. It was also found that a high saturated K/sub p/ value could not be reached at temperatures below 50/sup 0/C even when poled for long times.« less

A study of the effect of solution treatment, single and duplex isothermal aging heat treatments on an Fe-Ni-Ti-Al austenitic alloy hardened by ..gamma..' precipitation is reported. Sequential heat treatments were performed and studied in order to develop a systematic process for achieving very high strength austenite through thermal processing alone. Room temperature tensile tests were carried out. Alloys receiving double aging treatments were found to achieve mechanical properties superior to those aged at a given temperature. An optimum level of yield strength (172 Ksi) along with good elongation (20%) was obtained from a two-step aging process. Structural examination indicated that overaging was retarded by secondary aging. The formation and growth of cellular precipitates were suppressed. Resistivity changes were measured on wire specimens to study the early stages of precipitation. Resistivity peaks were observed during secondary aging indicating evidence of secondary precipitation.

The global economy has grown rapidly over the past decade with a commensurate growth in the demand for electricity services that has increased a country's vulnerability to energy supply disruptions. Increasing need of reliable and affordable electricity supply is a challenge which is before every Asia Pacific Partnership (APP) country. Collaboration between APP members has been extremely fruitful in identifying potential efficiency upgrades and implementing clean technology in the supply side of the power sector as well established the beginnings of collaboration. However, significantly more effort needs to be focused on demand side potential in each country. Demand side management or DSM in this case is a policy measure that promotes energy efficiency as an alternative to increasing electricity supply. It uses financial or other incentives to slow demand growth on condition that the incremental cost needed is less than the cost of increasing supply. Such DSM measures provide an alternative to building power supply capacity The type of financial incentives comprise of rebates (subsidies), tax exemptions, reduced interest loans, etc. Other approaches include the utilization of a cap and trade scheme to foster energy efficiency projects by creating a market where savings are valued. Under this scheme, greenhouse gas (GHG) emissions associated with the production of electricity are capped and electricity retailers are required to meet the target partially or entirely through energy efficiency activities. Implementation of DSM projects is very much in the early stages in several of the APP countries or localized to a regional part of the country. The purpose of this project is to review the different types of DSM programs experienced by APP countries and to estimate the overall future potential for cost-effective demand-side efficiency improvements in buildings sectors in the 7 APP countries through the year 2030. Overall, the savings potential is estimated to be 1.7 thousand TWh or 21percent of the 2030 projected base case electricity demand. Electricity savings potential ranges from a high of 38percent in India to a low of 9percent in Korea for the two sectors. Lighting, fans, and TV sets and lighting and refrigeration are the largest contributors to residential and commercial electricity savings respectively. This work presents a first estimates of the savings potential of DSM programs in APP countries. While the resulting estimates are based on detailed end-use data, it is worth keeping in mind that more work is needed to overcome limitation in data at this time of the project.

Adoption of efficient end-use technologies is one of the key measures for reducing greenhouse gas (GHG) emissions. How to effectively analyze and manage the costs associated with GHG reductions becomes extremely important for the industry and policy makers around the world. Energy-climate (EC) models are often used for analyzing the costs of reducing GHG emissions for various emission-reduction measures, because an accurate estimation of these costs is critical for identifying and choosing optimal emission reduction measures, and for developing related policy options to accelerate market adoption and technology implementation. However, accuracies of assessing of GHG-emission reduction costs by taking into account the adoption of energy efficiency technologies will depend on how well these end-use technologies are represented in integrated assessment models (IAM) and other energy-climate models.

March 18, 2011 Austin’s Home Performance with Energy Star Program: Making a Compelling Offer to a Financial Institution Partner Launched in 2006, over 8,700 residential energy upgrades have been completed through Austin Energy’s Home Performance with Energy Star (HPwES) program. 1 The program’s lending partner, Velocity Credit Union (VCU) has originated almost 1,800 loans, totaling approximately $12.5 million. Residential energy efficiency loans are typically small, and expensive to originate and service relative to larger financing products. National lenders have been hesitant to deliver attractive loan products to this small, but growing, residential market. In response, energy efficiency programs have found ways to partner with local and regional banks, credit unions, community development finance institutions (CDFIs) and co-ops to deliver energy efficiency financing to homeowners. VCU’s experience with the Austin Energy HPwES program highlights the potential benefits of energy efficiency programs to a lending partner. Encouraging Home Energy Upgrades in Austin The city of Austin, Texas has been operating residential energy efficiency programs since 1982. In 2006, Austin Energy (AE), the nation’s ninth largest community-owned public utility, launched a Home Performance with Energy Star (HPwES) program. Over 8,700 energy upgrades have been completed through this initiative to date. HPwES participants may choose rebates of up to 20 percent of the upgrade’s cost or low-interest unsecured financing through the program’s partner, Velocity Credit Union. 1 Austin Energy buys down the interest rate on these loans to between 0 and 6 percent depending on the This is the second in a series of LBNL Clean Energy Program Policy Briefs.

2011年3月18日奥斯汀的家庭能源之星计划:向金融机构合作伙伴提供令人信服的报价自2006年启动以来，通过奥斯汀能源公司的家庭能源之星(HPwES)计划，已经完成了8,700多个住宅能源升级。该项目的贷款合作伙伴Velocity Credit Union (VCU)已经发放了近1800笔贷款，总额约为1250万美元。与大型融资产品相比，住宅能效贷款通常规模较小，发放和服务成本较高。国家银行一直不愿向这个规模虽小但不断增长的住宅市场提供有吸引力的贷款产品。为此，能源效率项目找到了与地方和地区银行、信用合作社、社区发展金融机构和合作社合作的途径，向房主提供能源效率融资。VCU在Austin Energy HPwES项目中的经验突出了能源效率项目对贷款合作伙伴的潜在好处。德克萨斯州奥斯汀市自1982年以来一直在实施住宅能源效率计划。2006年，全国第九大社区公用事业公司奥斯汀能源公司(AE)推出了“家庭节能之星”(HPwES)项目。迄今为止，通过这一倡议已经完成了8700多项能源升级。HPwES的参与者可以选择获得高达升级成本20%的回扣，或者通过该计划的合作伙伴Velocity Credit Union提供低息无抵押融资。1奥斯汀能源公司将这些贷款的利率降低到0 - 6%，具体取决于LBNL清洁能源计划政策简报系列的第二部分。通过案例研究，这些工作论文强调了新出现的项目模型，新项目面临的重要问题，以及如何解决这些问题。本政策简报中描述的工作是由能源部能源效率和可再生能源、防候化和政府间项目办公室根据合同编号资助的。DE-AC02 - 05 ch11231。请直接向Mark Zimring (mzimring@lbl.gov)提出问题或意见。免责声明本文件是作为美国政府赞助的工作的说明而编写的。虽然本文件被认为包含正确的信息，但美国政府及其任何机构、加州大学校董会及其任何雇员均不对所披露的任何信息、设备、产品或过程的准确性、完整性或有用性作出任何明示或暗示的保证，或承担任何法律责任，或表示其使用不会侵犯私人拥有的权利。此处提及任何特定商业产品、工艺或服务的商品名称、商标、制造商或其他方式，并不一定构成或暗示其认可、推荐或受到美国政府或其任何机构或加州大学董事会的青睐。作者在此表达的观点和意见并不一定陈述或反映美国政府或其任何机构或加州大学董事会的观点和意见。作为能源部(Department of Energy)“更好的建筑”(Better Buildings)拨款的一部分，奥斯汀能源公司(Austin Energy)最近开展了“有史以来最优惠”(Best Offer Ever)的促销活动，参与者既可以获得回扣，也可以获得融资。通过这一倡议，预计将完成300多个综合能源升级。美国能源部的案例研究将提供“有史以来最佳报价”的更多细节。
