In order to achieve the emission reduction target for 2030, European Commission requires member countries that from the end of the decade onwards, only nearly zero-energy buildings (NZEB) are built. The renovation of the building stock is essential to achieve this goal. Working in consolidated urban contexts is very complex, so in this paper a solution to facilitate the process is proposed. This paper has developed a methodology for designing a roof extension and renovating an existing residential building as a measure of housing creation in already consolidated neighborhoods, and achieve a nZEB and ZEB renovated buildings. Based on typological classification of residential buildings, a single solution applicable to a multiple number of cases is provided to maximize the potential of the proposed solution. This solution was implemented in Chantrea neighborhood in Pamplona, Spain. The results show that it is possible to carry out the renovation of a residential building with a rooftop extension that complies with requirements for models nZEB and ZEB, and to apply this solution on 27 % of the neighborhood stock residential buildings. This would provide a reduction of total primary energy consumption of 62 % (nZEB) and 74 % (ZEB).

屋顶扩建作为nZEB建筑翻新解决方案。通过社区分类进行分类

为了实现2030年的减排目标,欧盟委员会要求成员国从本世纪末开始,仅建造近零能耗的建筑物(NZEB)。修stock房屋对于实现该目标至关重要。在统一的城市环境中工作非常复杂,因此在本文中提出了一种简化流程的解决方案。本文开发了一种方法,用于设计屋顶扩展和翻新现有的住宅建筑,作为在已经合并的社区中创造房屋的一种措施,并实现nZEB和ZEB翻新建筑。基于住宅建筑物的类型分类,提供了适用于多种情况的单个解决方案,以最大程度地提高所提出解决方案的潜力。该解决方案在西班牙潘普洛纳的Chantrea社区实施。结果表明,可以对符合nZEB和ZEB模型要求的屋顶扩展进行住宅建筑的翻新,并将此解决方案应用于27%的附近居民住宅建筑。这将使总一次能源消耗减少62%(nZEB)和74%(ZEB)。
