Growing Toward the Sun, Changing with the Wind 向阳而生，随风而动
This green office building in Nanjing's Jiangbei New Area is driven by wind and light environments, constructed using an L-shaped modular block system. The design creates the most efficient ventilation unit forms based on the wind conditions of both summer and winter. Ventilation openings flow through the blocks, and under the site’s unique wind and light conditions, organic cloud-like modules naturally form. The building's façade incorporates different strategies for opening based on the seasonal and functional ventilation requirements, ensuring optimal airflow throughout.
这座位于南京江北新区的绿色办公建筑，受风环境和光环境的驱动，采用L型模块积木的方式进行构建。根据夏冬两季的风环境，设计出最适宜通风的单元形态。在模块流出的通风孔洞处，结合场地特有的风光环境，自然生成并形成有机的云状模块。根据不同季节和功能的通风需求，建筑立面采取了灵活多变的开窗策略，以实现最佳的通风效果。
Winter and Summer Wind Environment 冬夏风环境
In summer, prevailing crosswinds dominate, and ventilation is organized through openings formed by the stacked blocks. In winter, all openings are closed, and the chimney effect is utilized to extract air from the central courtyard. 夏季穿堂风占主导，通过积木堆叠的体块形成的孔洞，进行通风组织。冬季关闭所有孔洞，利用烟囱效应进行中庭拔风。
Module System 模块开合
Variable Public Space 可变的公共空间
The building design incorporates a refuge level as a public space, offering a shared sky courtyard. During the summer, modular movable walls can be opened to facilitate optimal ventilation in the courtyard. At the same time, the building’s exterior features a water-retaining terracotta screen that can be adjusted in angle according to sunlight, adapting to various climatic needs. 建筑设计利用避难层作为公共空间，提供共享的空中庭院。夏季时，可打开模块化的活动墙面，实现中庭的良好通风。同时，建筑外立面的可蓄水陶土格栅也可根据日照进行角度调整，以适应不同的气候需求。
Shading Design 遮阳设计
Facade Screen and Daylighting 立面格栅与日照关系
The facade screen design is based on variability, with the shading panels carefully detailed to adjust their depth in different orientations. By adjusting the angle of the shading panels, the design ensures that the daylighting levels remain within comfortable values throughout the year. This study uses Radiance as a tool and, taking the southwest facade of the building as an example, simulates the daylighting values of a standard floor's individual rooms. Nine points represent the morning, twelve points represent noon, and three points represent the afternoon. The illuminance values at a height of 750mm above the floor are used as the study's focus. Literature research indicates that an illuminance range of 300-3000 lux is considered comfortable. After multiple simulations, the following diagram shows the optimal screen angles for daylighting during the spring equinox, summer solstice, autumn equinox, and winter solstice. 立面格栅的设计从可变性出发，遮阳板在不同方位的深度做了细节化设计，同时通过调整遮阳板的角度，实现全年采光照度处于舒适值的最大比例。本研究以 radiance 为工具，以建筑的西南立面为例，模拟了标准层单个房间的采光值。分别用 9 点代表上午，12 点代表中午，15 点代表下午，取室内距离地面 750mm 高度水平面的照度值作为研究对象。查阅文献资料表明，300-3000Lux 照度值为舒适照度。经多次模拟研究，下图分别表示了春分、夏至、秋分、冬至的采光最佳的格栅角度。
