摘要

本研究调查了在完全电气化的住宅建筑中采用可再生屋顶光伏系统的情况,并根据希腊的气候数据估算了零能源需求建筑的潜力。具体来说,分析的目的是计算出可能的最大层数,从而计算出完全转变为零净能耗建筑的总高度。能源分析使用 DesignBuilder 软件进行,主要针对单层至七层建筑。本研究的重要性在于承认了希腊住宅领域的多样性、对国家能源政策的遵守以及欧洲全面电气化建筑的目标。所考察的案例研究配备了电力驱动的空气-空气热泵,用于满足空间供暖和制冷需求,并配备了空气-水热泵,用于满足生活热水需求。调查地点是希腊的四个主要城市:雅典、塞萨洛尼基、夏尼亚和卡斯托里亚,它们代表了希腊的四个气候类别。通过分析,可以绘制出希腊气候数据的零能耗建筑潜力图,证明通过整合现场可再生能源和生产必要的电能,可以实现建筑能源的正平衡。本研究的新颖之处在于确定了一个关键因素,即建筑高度,它决定了将多户建筑改造为零能耗建筑的可行性。根据分析结果,计算出香尼亚的临界层数为 6 层,雅典为 5 层,塞萨洛尼基为 4 层,卡斯托里亚为 2 层。就三层住宅楼而言,采用可再生光伏系统后,每年的剩余电量分别为 13741 千瓦时(夏尼亚)、10424 千瓦时(雅典)和 6931 千瓦时(塞萨洛尼基),相应的覆盖率分别为 100%(夏尼亚)、69.0%(雅典)、38.9%(塞萨洛尼基)和 0%(卡斯托里亚)。

Mapping the Potential of Zero-Energy Building in Greece Using Roof Photovoltaics
 The present study investigates the incorporation of renewable rooftop photovoltaic systems in fully electrified residential buildings and estimates the zero-energy demand building potential in relation to the climatic data of Greece. Specifically, the aim of the analysis is to calculate the maximum possible number of stories and therefore the total building height for a complete transformation to zero-net-energy building. The energy analysis, which is conducted using the DesignBuilder software, focuses on single-floor up to seven-story buildings. The importance of the present work lies in the acknowledgment of the diversity of the Greek residential sector, the adherence to national energy policies, and the European goal of fully electrified buildings. The examined case studies are equipped with electrically driven air-to-air heat pumps serving the space heating and cooling demands and with an air-to-water heat pump covering the domestic hot water requirements. The investigated locations are the four main cities of Greece, Athens, Thessaloniki, Chania, and Kastoria, which represent the country’s four climatic categories. The conducted analysis allows for the mapping of the zero-energy building potential for the climatic data of Greece, demonstrating the possibility of striking a positive building energy balance through the integration of on-site renewable energy sources and the production of necessary electrical energy. The novelty of the present work lies in the identification of a key factor, namely, the building height, which determines the feasibility of transforming multifamily buildings into zero-energy buildings. According to the analysis results, the critical number of stories is calculated at six for Chania, five for Athens, four for Thessaloniki, and two for Kastoria. Regarding a three-story residential building, the incorporation of a renewable photovoltaic system can result in an annual surplus electricity production of 13,741 kWh (Chania), 10,424 kWh (Athens), and 6931 kWh (Thessaloniki), and a corresponding coverage of 100% (Chania), 69.0% (Athens), 38.9% (Thessaloniki) and 0% (Kastoria).
