    Settlement scale analysis approach to reach nearly zero energy communities
    (Springer, 2020-01-01) Özdemir, Ece Kalaycıoğlu; Yılmaz, A. Z.; Architecture; KALAYCIOĞLU, Ece
    The European Union directive on the energy performance of buildings was revised and republished in 2010, as EPBD Recast, introducing new terms as cost-optimal and nearly zero energy levels. It mandated that by 2018 all new public buildings and by 2020 all new buildings will be constructed as nearly zero energy building. Thus, it proposed the calculation of long-term energy-related costs of buildings together with the annual primary energy consumption, as the cost-optimal calculation framework. In the study, the cost-optimal calculation framework of EPBD was adapted to settlements (a group of buildings) connected to district energy systems. Numerous energy efficiency measures were applied to the reference buildings to reach cost-optimal and nearly zero energy levels. Then the procedure was repeated at settlement scale including the district energy system alternatives. As a result, both at building and settlement scale, reference, cost-optimal and nearly zero energy cases were determined. This paper was also focused on the effectiveness of renewable energy systems for each three energy performance levels of buildings and settlements. Renewable energy systems have a significant role to reach the nearly zero energy levels both at building and settlement scale. However, their effect on the economy should be analysed carefully by government bodies. The nearly zero energy levels for different types of buildings and settlements located in different climates in a country should be determined depending on the politics of energy, economy and social services.

    Settlement scale analysis approach to reach nearly zero energy communities
    (EDP Sciences, 2019) Kalaycıoğlu, Ece; Yılmaz, A. Z.; Architecture; Kurnitski, J.; Wargocki, P.; Mazzarela, L.; Zhang, H.; Nastase, I.; Tanabe, S.; Gameiro da Silva, M. C.; Cao, G.; Inard, C.; KALAYCIOĞLU, Ece
    Looking at the recent developments, the European Union (EU) aims to become a zero carbon community. For the building sector, Energy Performance of Buildings Directive (EPBD) was recast in 2010 introducing the definition of the nearly zero energy building (NZEB) levels to construct all new buildings at this level by the end of 2020. The last revision of the directive in 2018 also promotes the renovation of the building stock to the NZEB levels. In the paper, it was proposed to define the nearly zero energy levels for settlements. This way, it was aimed to discuss the advantages and disadvantages of reaching the nearly zero energy levels at larger scales than single buildings. Settlement level studies, including the district energy systems, intended to reveal the energy efficiency measures which lead to optimal cost levels for more than one building. Key parameters were examined for a new settlement design which may be beneficial for the large-scale renewable energy system implementation and district energy system (DES) usage with high energy performance buildings.
