There is an ongoing, global discussion on the ways to obtain Net Zero Energy Buildings (NZEBs). Nonetheless, little attention was given on the application of NZEBs in warm climates, especially in Brazil. Therefore, the aim of this article is to propose retrofit guidelines that meet a net zero energy target for four-story office buildings in the climactic conditions within Brasilia. Through this research 240 office buildings in the downtown area of the Brazilian capital were morphologically characterized, which served as the basis for the definition of a representative model of the four-story office buildings. The model variations – 69 in total – were tested taking in consideration a combination of building skin variables, following recommendations from the literature, and national energy efficiency standards. Simulations were then carried out in Design Builder and Diva to predict final energy consumption for air-conditioning, lighting, and office equipment, and simultaneously, solar photovoltaic energy production on the building skin of the respective models – on the roof, and on the North, East and West facades in PVSYST. Results showed a 46% reduction of the total final energy consumption in the optimized model. This paper showed that it is possible to achieve the NZEB goal in the up-to-four-story office buildings in the climate zone of Brasilia. Thus, the paper provides what was needed to draft a series of guidelines and strategies to use in the energetic renovation of the building complex, buildings towards the achievement of the NZEB goal in the climate zone of Brasilia. The novelty of this research is to apply the concept of NZEB in existing office buildings in Brasilia.

关于获取净零能耗建筑物（NZEB）的方式，目前正在进行全球讨论。尽管如此，在温暖的气候下，特别是在巴西，对NZEBs的应用却鲜有关注。因此，本文的目的是提出在巴西利亚气候极端条件下，满足四层办公楼净零能耗目标的改造指南。通过这项研究，对巴西首都市区的240栋办公楼进行了形态学表征，为定义四层办公楼的代表性模型提供了依据。结合文献中的建议和国家能效标准，考虑了建筑外观变量的组合，对模型变体（总共69个）进行了测试。然后在Design Builder和Diva中进行了模拟，以预测空调，照明和办公设备的最终能耗，同时预测各个模型的建筑表皮（屋顶和北部）的太阳能光伏发电量。 ，PVSYST中的东西立面。结果表明，在优化模型中，最终总能耗降低了46％。本文表明，在巴西利亚气候区的四层以上的办公楼中可以实现NZEB的目标。因此，本文提供了起草一系列指南和策略以用于建筑物综合体，为实现巴西利亚气候带中的NZEB目标而进行的建筑物翻修所需的内容。
