In this scope, artificial lighting results and daylighting availability of the library space is analyzed with a lighting simulation tool. Accordingly, solar gains were examined and the annual energy loads were calculated depending on a variety of façade shading configurations via a building energy simulation program.","PeriodicalId":241572,"journal":{"name":"2019 Second Balkan Junior Conference on Lighting (Balkan Light Junior)","volume":"45 1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130234398","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}

Except for the simulation model of the architectural lighting of the building, a lot of experiments and preconditions are made. All the surfaces of the building are experimentally tested and their reflective properties are obtained. Test flood lights are chosen according to the reflectance of the surfaces and their color characteristics are experimentally tested. Based on these experimental results, on site experiments are also made and after that the whole idea of the architectural lighting of the twelfth educational building of TU Sofia is simulated. The simulation gives an idea very close to the night look of the building (if the concept is accepted and realized), based on the real characteristics of surfaces and luminaires.","PeriodicalId":241572,"journal":{"name":"2019 Second Balkan Junior Conference on Lighting (Balkan Light Junior)","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114514441","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}

Green electricity use is the perfect logical addition to an energy efficient building. Such electricity can be obtained from sunlight using a photovoltaic panel. Most photovoltaic panels have a CPA approximately 20%, reached at 25°C. It means that at the outlet on the panel surface the transformed electrical energy is maximum 20% of the solar energy. The panel should have a temperature 25°C and be perpendicular to the sun's rays in order to use all of the panel's capabilities. These conditions can be achieved with a sun monitoring system. That publication reveals the creation of such a system.","PeriodicalId":241572,"journal":{"name":"2019 Second Balkan Junior Conference on Lighting (Balkan Light Junior)","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128520622","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}

Energy efficiency, Lighting techniques and lighting accessories play a vital rule both in the terms of global warming and as well energy saving which leads it to economic efficiency of lighting, its benefits and impacts on both aspects, whether economic side or environmental issues. The paper will be based on two issues which are energy efficiency and economic aspects of lighting. A general overview will be given about energy efficiency, its benefits, tips, and economic aspects of energy efficiency while for economic aspects of lighting will be illustrated specifically that how with energy saving techniques and less energy consumption luminaries, lighting can bring changes in both economic and environmental aspects.","PeriodicalId":241572,"journal":{"name":"2019 Second Balkan Junior Conference on Lighting (Balkan Light Junior)","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134257358","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}
