The operation mode of heating, cooling and air conditioning systems and outdoor temperatures are important parameters for thermal comfort. As a result of experimental studies, Fanger formed an indicator called the “Predicted Mean Vote (PMV) “ and determined PMV=0 as the best value for comfort. In this study, first case building envelope properties were determined for four different cities representing four climatic regions of Turkey. Then thermal comfort temperatures were determined for each city and finally energy performance of the case buildings were evaluated based on these thermal comfort temperatures. The HVAC system was chosen as full mechanically controlled without allowing any personal intervention, analysed for both intermittent and continuous regimes. The study aims to exhibit user satisfaction and energy consumption change for each city when PMV=0. Statistical analysis of PMV values showed that although intermittent regime for Izmir gives lower energy consumption, continuous regime is better for Istanbul. For all cities, continuous regime consumes 4,5-6,2% more energy (kWh/m²) for heating, 9,1-23,2% for cooling comparing with intermittent regime.","PeriodicalId":272339,"journal":{"name":"Mühendis ve Makina","volume":"57 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-01-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132156499","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}

By explaining the product life cycle phases of PLM, the effects of digitalization in each phase have been explained. Digitalization, the concept of digital twin and its applications are mentioned and the stages it affects in the product life cycle are explained. Then, by mentioning the relationship between PLM and digitalization, the effects of digitalization on the beginning of product (BOL), mid-product (MOL) and end-of-product (EOL) stages are explained. As a result, it is possible to state that a meaningful digitalization will be possible with PLM and that the process starting with COVID - 19 will contribute to the spread of the PLM concept and to increase awareness, since digitalization and PLM are concepts that complement each other.","PeriodicalId":272339,"journal":{"name":"Mühendis ve Makina","volume":"72 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134559967","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}
