This study presents the theoretical energy savings in low energy buildings with interior wooden surfaces under different moisture protocols indoors. The requirements of the Norwegian Building Regulations (TEK10) are followed regarding the U-values of the envelope components. A hygrothermal simulation tool is employed to estimate the potential diurnal variations of moisture content in the wood structure.

The use of daylight in school buildings has been the subject of study in the past, since the proper use of daylight in schools is liable to improve student performance and to provide energy savings. It is also believed that natural lighting has affected the design of school buildings more than any other building type while the main problem is located on quality rather than on quantity issues. The paper investigates the extent to which the implementation of certain interventions to the building envelope of existing schools, can improve their energy performance and at the same time ensure thermal and visual comfort. A Primary school in the C climatic zone is used as a case study in order to examine energy performance and daylight issues for a relatively new school building with unfavorable orientation. The effect of alternative interventions such as the implementation of thermal insulation, the use of ceiling fans, the implementation of external shading, and the improvement of thermal characteristics of openings are being examined. The evaluation is performed using appropriate energy performance and daylight simulation tools.</p></div>","PeriodicalId":20460,"journal":{"name":"Procedia environmental sciences","volume":"38 ","pages":"Pages 204-211"},"PeriodicalIF":0.0,"publicationDate":"2017-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/j.proenv.2017.03.107","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82099897","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Thus, Green Architecture appeared as a sort of historical reconciliation with the environment. Meanwhile, the majority of the developing countries including Egypt showed an intensive increment in the building's volume that were blind copied from the current international architectural trends neglecting any environmental aspects. On the other hand, the Egyptian historical heritage, particularly old Cairo districts, used to give great respect to the climatic conditions of their environment while maintaining the unique value of their architectural style. Therefore, this research aims to focus on this Egyptian architectural of the historical Cairo are to study and analyse its environmental aspects and treatments in order to derive their architectural bases that are suitable for their local environment with Egyptian green methods. The research was carried out through two main phases; the first phase was based on a theoretical analytical study of a specific house form Historical Cairo, El El-Suhaimi house, while the second empirical phase was conducted for the same case study using simulation methods through Design Builder simulation software in order to assure that all findings conform to the recommended ones that could achieve the desired thermal comfort. The results of the case study showed great potentials in using the passive designs methods of this historical house to enhance thermal comfort in residential buildings which located in hot arid climates. Thus, this paper concludes that the traditional architecture, specifically the historical Cairo architecture, proved to be suitable to become a permanent reference to make use of its elements and particulars in the formation of modern green architecture of a local identity and style.</p></div>","PeriodicalId":20460,"journal":{"name":"Procedia environmental sciences","volume":"37 ","pages":"Pages 342-355"},"PeriodicalIF":0.0,"publicationDate":"2017-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/j.proenv.2017.03.064","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79692759","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
