可持续性

北翼利用一个闭环地热热泵系统来调节空间. There are 15 vertical wells, each 540 feet deep. 热泵根据空间的需要将热量输送到地热回路或从地热回路输送出去.

它是如何工作的:
Ground temperatures are a constant 55˚F. During the winter, 热量通过地热表面从地面转移到北翼. 在夏季，热量从北翼转移到地面.

Positive impact:
Geothermal loop systems are energy efficient, environmentally clean, and cost-effective method of space conditioning. Operating cost is reduced because there is no outdoor unit to power. 没有排放，因为没有燃烧，这增加了安全性.

与传统设备相比，线上买球平台的采暖通风和空调(HVAC)设备显著节省了能源. 所选择的设备采用现代技术和控制技术，如能量回收通风(ERV)装置，以减少电气负荷, demand control ventilation, and variable frequency drives.

As part of summer 2020 renovations, 线上买球平台将伯纳姆历史建筑中的暖通空调系统换成了环保系统, best-in-class model that replaces fresh air in the building twice an hour. 每个教室空间现在将由系统单独服务，而不混合新风和回风. The construction, 在冠状病毒大流行之前，原定于2020年夏季举行的是哪一次, 使学校能够采用先进的氧化技术和紫外线杀菌照射(UVGI)，结合高效的暖通空调系统，以减少空气传播疾病. 幸运的是，这个时机让学校在改善空气质量和降低空气暴露风险方面做得更好.

In the rented 中学 suite, additional air purifiers and filters improve ventilation inside the classrooms.

There are two AAON ERV units that condition the air in the North Wing. ERV单元在排出的空气中交换能量，并使用干燥剂对进入的外部空气进行预处理. This improves the indoor air quality, and at the same time the equipment capacity can be reduced, which decreases the electrical energy needed to heat and cool the space. 

需求控制通风是一种技术，当居住者需要时，允许空间满足学校的新鲜空气需求. 每个小组会议空间都有一个二氧化碳传感器，用于确定通风需求. 随着通风需求的增加，通过风扇的加速来增加外部空气的量. As ventilation need decreases, the amount of outside air is decreased by decreasing the speed of the fan.

增加或减少风扇速度的能力是由于变频驱动. Variable frequency tires (VFDs) can reduce noise, 减少磨损, and reduce electrical charges by only delivering the amount of power necessary. 事实上, all of the pumps, 供应球迷, 排气风扇, 能量回收轮配备变速运行，以最大限度地提高舒适性和效率.

北翼采用高性能材料建造，最大限度地节约能源, 安慰, and building integrity. 高声学等级的材料用于隔离空间之间的噪音，并尽量减少暖通空调的噪音.

The new structure features a green roof that efficiently manages storm water. 屋顶, 结合高性能建筑材料也有助于良好的隔热空间, which lessens the energy needed for cooling or heating the space. A 6.3kW的屋顶光伏阵列为节能建筑提供可再生能源.

蒙台梭利哲学非常强调关心和理解自然世界. 教育学生了解可持续发展的相关科学和道德责任是融入基亚拉瓦莱社区所做的一切. 蹒跚学步的s tend to the garden. Preschoolers sort recycling. 小学 children work to restore endangered prairie lands. Upper 小学 and 中学 students take outdoor education trips.

可持续发展教育从幼儿阶段开始，一直持续到中学阶段. The curriculum includes botany, 动物学, 生命科学, 营养, and health education at each developmental stage. 学生们学习实用的生活技能，比如如何照料花园，如何用自己种植的农产品做饭. 教室里有宠物和植物，所以即使是最小的孩子也学会照顾其他生物. Students learn to identify and practice healthy choices in food and behavior. There is an educational dashboard for students to track energy usage. Service learning includes prairie stewardship, trips to the woods, and gardening. 到了中学，学生们每年都会组织多次自己的露营旅行.
