Yet, the embodied energy payback period is not taken into consideration, in relation to the respective energy savings; this payback period is considered to be very crucial since it is an indicator of whether the specific energy saving measures should be followed, so that their embodied energy is paid back within the rest of the building's life span, showing finally whether the building should be energy upgraded or not, from a holistic energy point of view.</p><p>In this work a “typical” dwelling building apartment is considered in all four climatic zones of Greece. Materials and techniques are examined on this building, so as to achieve the minimum requirements of the existing legislative energy upgrade, as well as transforming it into a nearly zero energy building (nZEB). The parameters used are according to the Greek legislationwith regards to occupancy and building use. Materials and techniques investigated are chosen with market availability criteria. A parametric analysis of materials and techniques with different embodied energies is considered and their payback periods are examined for all case studies. Conclusions are drawn on which materials and techniques should be preferred and which should be avoided for the energy upgrade of existing buildings in the climatic zones of Greece, in order to achieve the minimum legislative energy consumption requirements or an nZEB, based on their energy payback period.</p></div>","PeriodicalId":20460,"journal":{"name":"Procedia environmental sciences","volume":"38 ","pages":"Pages 196-203"},"PeriodicalIF":0.0,"publicationDate":"2017-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/j.proenv.2017.03.106","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86208892","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}

The external skin of the double skin façade is made out of rotating sandblasted striped glass louvres on its external skin on both elevations. During the cooling season, measurements were done on both elevations with the intention to examine in detail the performance of the curtain walling. Measurements were done using thermocouples in particular areas of the construction for several days and different methods were followed to allow the determination of the airflow in the cavity. The external skin which is adjustable was examined in vertical and inclined position with the aim to identify when it is performing properly and how its performance can be optimized. Throughout the analysis, it was realised that the South elevation is functioning ideally thanks to a multi-layered shading that is achieved by the sandblasted striped glass louvres when they are positioned inclined. On the contrary, it can be identified that the west elevation is not performing sufficiently as the vector of the solar irradiance is differing in comparison to the midday where the irradiation is facing the south orientation from a significantly different position. As a result the multi-layered shading in the west elevation is not functioning properly and for this reason the measured temperatures on both the internal skin of the Double Skin Façade and the interior of the building prove that corrective measures are required with the aim to avoid overheating problems.</p></div>","PeriodicalId":20460,"journal":{"name":"Procedia environmental sciences","volume":"38 ","pages":"Pages 86-93"},"PeriodicalIF":0.0,"publicationDate":"2017-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/j.proenv.2017.03.083","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89053580","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}

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}

Life Cycle Energy Analysis (LCEA) of 90 case studies of residential buildings is evaluated with a specific focus on the normalization procedure that follows the principles of Product Category Rule (PCR) 2014:02 for buildings. The normalization procedure provided a minimization of the sample by considering issues of comparability, the omissions in the boundaries of the system, the LCI method and the updating on the energy efficiency definition of the building. Results indicate that the use of different LCI methods leads to an important fluctuation in the absolute values of embodied energy as the embodied energy of annZEB calculated with process analysis is lower than every case study calculated with hybrid input-output analysis without including nZEBs. The share of embodied energy in low energy buildings could reach up to 57% -or even up to 83% when renewable energy sources are used for electricity production- and in nZEBs up to 100% even though a significant reduction in the total life cycle energy is identified. The increase in embodied energy and a difference of at least 17% in the share of embodied energy between low energy and nearly zero energy buildings indicate that maybe LCEA should be considered in energy efficiency regulations along with further standardization.</p></div>","PeriodicalId":20460,"journal":{"name":"Procedia environmental sciences","volume":"38 ","pages":"Pages 554-561"},"PeriodicalIF":0.0,"publicationDate":"2017-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/j.proenv.2017.03.123","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89073404","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}
