This paper brings together various concerns that have been expressed in DC distribution at low voltages for consumption in domestic and other building needs. The paper presents various arguments and attempts to arrive at a solution from various points of view. A suitable voltage level of 48 V, and a suitable distribution scheme are presented along with some field experiences of installation of such systems.","PeriodicalId":339120,"journal":{"name":"2016 First International Conference on Sustainable Green Buildings and Communities (SGBC)","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117163339","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}

A comparison of Alternating Current(AC) and Direct Current(DC) LED lights efficiencies has been done. We have also evaluated the driver efficiency and thermal stability for both AC and DC lights. Experiments have been conducted on the life-test of DC LED tube-light. The result shows that DC LED lights are more efficient and reliable than AC lights.","PeriodicalId":339120,"journal":{"name":"2016 First International Conference on Sustainable Green Buildings and Communities (SGBC)","volume":"110 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122714356","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}

Any smart meter needs an infrastructure, wired/wireless, for data communication with the central server. To enable this two-way communication link, we propose a narrowband Power Line Communication (PLC) system operating at a rate of few kbps and this can be deployed over existing outdoor/indoor power lines. Our design demonstrates reusing the existing wired electrical network to provide communication between the smart meter and a central server. A low-cost dedicated hardware for measuring the power usage of electrical appliance is designed. Further, a user interface is developed to remotely access the power usage measurements stored at the central hub database with features of power management. With the usage data at hand, smart decisions can be made in saving energy and, reducing carbon foot-prints. Our design uses low cost and off the shelf devices and no additional wiring as it communicates over the existing power line infrastructure.","PeriodicalId":339120,"journal":{"name":"2016 First International Conference on Sustainable Green Buildings and Communities (SGBC)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123788114","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}
