Initial minimum efficiency levels for products falling under these categories were established in EPACT, based on the requirements in ASHRAE/IES Standard 90.1-1989. EPCA requirements state that, if the American Society of Heating, Refrigerating and Air-Conditioning Engineers, Inc. (ASHRAE) amends efficiency levels prescribed in Standard 90.1-1989, then DOE must establish an amended uniform national manufacturing standard at the minimum level specified in amended Standard 90.1.\u0000 On October 29, 1999, ASHRAE approved the amended Standard 90.1 (Standard 90.1-1999), which increases the minimum efficiency levels for some of the commercial HVAC and SWH equipment covered by EPCA 92. DOE asked Pacific Northwest National Laboratory (PNNL)2 to conduct a screening analysis to determine the energy-savings potential of the efficiency levels listed in Standard 90.1-1999. The analysis estimated the annual national energy savings and carbon emissions reductions that would result if the EPACT-covered products were required to meet these efficiency levels, and additional energy-savings potential for these products if they exceeded these levels.\u0000 From 2004 through 2030, the estimated national energy savings achieved by adopting Standard 90.1-1999 efficiency levels for spacecooling equipment is about 3 quadrillion Btu (quads3). The energy savings potential for space-heating equipment is about 0.5 quad and for water-heating equipment is about 0.06 quad. The cumulative commercial-sector building energy consumption during the same time period is estimated to be 485 quads. The total carbon emissions reduction is about 52 millions of metric tons (MMtons).","PeriodicalId":186011,"journal":{"name":"Successfully Managing the Risk and Development of Your Business and Technology","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2000-04-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128651306","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The need to develop and use resources such as solar energy, wind, and biomass has assumed even greater importance in view of the concern for environmental damage that could occur if all of the anticipated power demand in the expanding economies were met by fossil fuels.\u0000 Recent advances in wind energy technology have made it economically competitive with fossil-fuel-generated electricity, wherever sufficient wind resource is available. Solar thermal power can be economically competitive when compared with coal-generated electricity if environmental costs are accounted for (Goswami, 1994). However, without considering such environmental costs (a realistic scenario for developing countries like India and China) solar power may not be competitive at present because of the high capital costs. The potential exists for reducing these expenses by improving the performance of thermal power systems. The system performance can be improved by employing new and innovative ideas in thermal power cycles. This article reviews some of these ideas and research needs to make solar thermal power cost competitive.","PeriodicalId":186011,"journal":{"name":"Successfully Managing the Risk and Development of Your Business and Technology","volume":"62 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1998-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126738410","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
