格拉诺农场成立于2006年，是密歇根州西南部第一个经过认证的有机蔬菜农场，它再次扩大了其场地和为当地社区提供的服务。新建的格兰诺温室实现了农场的目标，即在一个屋檐下为食品教育、生产和公民创造一个有创意的程序和条件的空间。考虑到农业经济和实用性，这个预制的7,336平方英尺的玻璃结构使农场工作人员、厨师、Farmcamp青年、游客和食客沉浸在一个工作的蔬菜农场中，同时愉快地吸引他们的五种感官。
Established in 2006, Granor Farm, the first certified organic vegetable farm in Southwest Michigan has once again expanded its site and offerings to its local community. The newly constructed Granor Greenhouse achieves the farm’s goals of creating an inventively programmed and conditioned space for food education, production, and citizenry under one roof. With agrarian economy and utility in mind, the prefabricated 7,336-sf glass structure immerses farm staff, chefs, Farmcamp youth, visitors, and diners into a working vegetable farm while delightfully engaging all of their five senses.
该建筑的设计是为了 “融入 “现有的农场和乡土类型。镀锌钢、磨光的铝和涂有 “Farmall红 “的门，在视觉上将其与农场的其他建筑联系起来。
The building was designed to “fit in” to the existing farm and vernacular typologies. Galvanized steel, mill-finished aluminum, and doors painted “Farmall red”, visually tie it to the other buildings on the farm.
建筑物朝南收集阳光，利用Venlo温室系统将其多样化的项目分为三个区域，并采用相关的玻璃策略。中心区的设计是为了最大限度地提高项目的灵活性，它使用透明的玻璃来提供无障碍的视野，让人们可以看到上面的田野和天空。在东部和西部区域，包括用于生产幼苗/发芽的空间，半透明的玻璃提供了最具扩散性的理想生长环境。
Harvesting the sun with its broadside facing south, the building utilizes the Venlo greenhouse system to organize its diverse program into three zones with associated glazing strategies. The central zone, designed for maximum program flexibility, uses clear glass to provide unencumbered views out to the fields and sky above. In the eastern and western zones, which include space for the production of seedlings/germination, translucent glass provides the most diffuse, ideal growing environment.
在中心区，永远存在的厨房支持日常食品和面包的生产，这些食品和面包是由农场种植的原料制成的。它也是Granor非常成功的餐饮项目的支柱，在抛光的混凝土地板上安装了可移动的家具，使空间可以轻松地从生产设施转变为社区和餐饮活动的场所。
In the center zone, the ever-present kitchen supports daily food and bakery production made from ingredients grown on the farm. It also anchors Granor’s highly successful dining program that incorporates movable furniture over the polished concrete floor, allowing the space to easily transform from a production facility to a place for community and dining events.
在主要社交空间的书架上，两个花旗松包覆的体量在各区域之间提供了战略分隔，容纳了 “杂物间”、盥洗室、储藏室和办公室。木头软化了凉爽的饰面，同时屏蔽了包裹在体积表面的吸音。头顶上的遮阳板缓和了混响，形成一个声学上舒适的社交空间。
Bookending the main social space, two Douglas Fir clad volumes provide strategic separation between the zones, housing the “mudroom”, washrooms, pantry, and office. The wood softens the cool finishes while screening the acoustic absorption that wraps the faces of the volumes. Overhead shades temper reverberation to make an acoustically comfortable social space.
温室的调节需要一个创新的加热和冷却方法。温室围墙配备了自动、可操作的通风口，在温和的日子里自然调节室内空气温度。在冬季，地板内的辐射水力管道将热量引入到居住者身边，而可变制冷剂流量（VRF）系统则从上面增加额外的热量。为了减轻玻璃屋顶上形成的冷凝水，辐射水力管道在每个山谷下的中央区域的长度上运行。在夏季，VRF系统、减温风扇和头顶上的可伸缩水平反射式遮阳板管理来自太阳的热增益，以保持中央区域的舒适性，满足其多种用途。
Conditioning the greenhouse required an innovative heating and cooling approach. The greenhouse enclosure is equipped with automated, operable vents that naturally modulate the inside air temperature during temperate days. During winter, radiant hydronic piping within the floor introduces heat close to occupants while a Variable Refrigerant Flow (VRF) system adds additional heat from above. To mitigate condensation forming on the glass roof, radiant hydronic fin tubes run the length of the central zone under each valley. In summer, the VRF system, destratification fans, and overhead, retractable horizontal reflective shades manage heat gain from the sun to keep the central zone comfortable for its many uses.
项目的灵活性和玻璃的广泛使用给每个空间的照明带来了挑战。丰富的日光被可操作的水平遮阳板所调和，木质的体量被圆形的 “屋顶 “开口所点缀，每个空间在白天都有自然光照明。晚间用餐则是一个不同的挑战。一个长满草的护堤挡住了车辆的车灯，使其无法照射到院子里。走路要靠脚下的灯光。一旦进入，照明策略的每一个元素都增强了体验的亲密性。一个统一的筒灯网格，带有温暖的调光，专门照亮了空间的水平表面，同时最大限度地减少了反射，使人们可以看到外面的夜色。
Program flexibility and extensive use of glass posed challenges for lighting each space. Abundant daylight is tempered by the operable horizontal shades, and with the wood volumes punctuated with round “roof” openings, every space is lit by day by natural light. Evening dining created a different challenge. A grassy berm shields vehicular headlights from shining into the grounds. The approach is by footlight. Once inside, every element of the lighting strategy enhances the intimacy of the experience. A uniform grid of downlights with warm dimming specifically illuminates the horizontal surfaces of the space while minimizing reflections, allowing views out into the night.
