位于俄勒冈州波特兰郊区莱克奥斯威戈（Lake Oswego）的河谷小学（River Grove Elementary School）近日完成了全新升级改造。此次改造由Arcadis凯谛思负责，秉承现代化和可持续发展的设计理念，全面提升了学校的功能与设施强度。

River Grove Elementary School, located in the suburban area of Lake Oswego, Portland, Oregon, has recently undergone a comprehensive upgrade. The renovation, led by Arcadis, adheres to modern and sustainable design principles, significantly enhancing the school's functionality and facility resilience.

该校原址始建于1967年，占地6,400平方米。改造后，占地面积扩展至约7,300平方米，并成为美国首批配备微电网系统的学校之一。

Originally built in 1967, the school covered an area of 6,400 square meters. After the renovation, the area expanded to approximately 7,300 square meters, making it one of the first schools in the United States to be equipped with a microgrid system.

在抗灾能力方面，河谷小学采用了更高的抗震标准，能够在地震等自然灾害发生时为当地居民提供完善的防灾避险能力，从而成为重要的社区资源。凭借全电气化设计和突出的抗灾能力，改建后的河谷小学不仅在能源自主和灾害应对方面取得了显著进步，也以其前瞻性树立了未来教育建筑的新标准。

In terms of disaster resilience, River Grove Elementary School has adopted higher seismic standards, enabling it to provide robust disaster prevention and evacuation capabilities for local residents during natural disasters such as earthquakes. With its fully electric design and exceptional disaster resilience, the renovated River Grove Elementary School has not only made significant advancements in energy independence and disaster response but has also set a forward-thinking new standard for future educational buildings.

01

绿色节能转型，可持续设计新示范

河谷小学采用高效的风冷式冷水机组为教室降温，确保学生在舒适环境中专注学习。建筑的机械通风系统配备高MERV等级的过滤器，输送100%的外部空气，有效提升空气质量并应对季节性野火引起的大气烟雾问题。此外，热回收通风（HRV）系统通过从排出的废气中回收热量，减少冬季供暖的能源消耗和运营成本。

River Grove Elementary School utilizes highly efficient air-cooled chillers to cool classrooms, supporting students for an active and attentive learning environment. 100% outside air is delivered through the building ventilation through MERV filters, preparing for the increased likelihood of seasonal atmospheric smoke with the proliferation of wildfire events. Heat is recovered from exhaust air as it leaves the building, reducing the amount of energy needed to heat the building in the winter as well as operational costs.

学校还采用自动调光照明技术，根据自然光水平调节室内亮度，降低能耗的同时确保舒适的学习光照环境。太阳能涂层和外部遮阳装置则帮助减少窗户的热负荷，从而降低冷却需求并控制教室内的眩光。

Lighting fixtures automatically dim when light levels are reached through sunlight, reducing energy use and maintaining a comfortable light level in the learning environment. Solar coatings and exterior shades reduce heat loads on exterior windows, minimizing heat loads and controlling glare in the classrooms.

创新微电网系统，社区韧性全升级

河谷小学配备了一个独立于区域电网运行的微电网系统。学校屋顶安装的150kW光伏（PV）阵列每年可产生相当于建筑年能耗10%的电力。作为微电网系统的“大脑”，可编程微电网控制器在电力中断时会自动切换到“孤岛模式（Island Mode）”，保持系统的稳定运行；还可以将未使用的多余光伏能量存储在电池储能系统（BESS）中，以削减公用电网负荷高峰时的电力需求，从而增强电网韧性并最大限度地减少碳排放。

River Grove Elementary School is equipped with a microgrid system that operates independently from the regional power grid. A 150 kW Photovoltaic (PV) rooftop array generates 10% of the building's annual energy consumption. The programmable microgrid controller is the “brain” of the system and lives in the main electrical room. The controller automatically switches the system between “default” and “island” mode in the case of a power outage, maintaining stable system operation. The controller will also store surplus PV energy (not being used by the building) in the battery energy storage system (BESS) and shave peak electrical load demands when the utility grid is strained, adding to grid resilience and minimizing carbon emissions.

通过结合使用BESS和发电机电力，河谷小学可在停电期间为公共区和体育馆的暖通空调（HVAC）、电气、技术和管道系统提供应急电力，确保持续运行。这一设计不仅在自然灾害或长期大范围停电期间为社区提供重要服务，提升了学校的应急响应能力，也为社区的整体韧性建设做出了重要贡献。

By combining the use of BESS and generator power, River Grove Elementary School can provide prolonged emergency power to HVAC, electrical, technology, and plumbing systems in common areas and the gym during outages, ensuring continuous operation. This design not only provides critical services to the community during natural disasters or prolonged widespread power outages, enhancing the school's emergency response capability but also significantly contributes to the overall resilience of the community.

03

全维度学习空间，打造多元教育生态

河谷小学作为一所先进的教育设施，其设计旨在满足每一位学习者的需求，提供多种教育和活动空间，包括教室、扩展学习区、创新实验室、音乐室、展示舞台、图书馆、行政办公室、体育馆、厨房、半室外活动区、户外学习空间和运动场。

River Grove Elementary School, as an advanced educational facility, is designed to meet the needs of every learner by providing a variety of educational and activity spaces. These include classrooms, extended learning areas, innovation labs, music rooms, performance stages, a library, administrative offices, a gymnasium, a kitchen, semi-outdoor activity areas, outdoor learning spaces, and sports fields.

针对学生的多样化学习方式，学校提供了适合不同规模集会的活动空间、专注工作的安静空间，以及团队协作的活跃空间。例如，L型教室设计提供分区和分组支持，能够满足一对一学习、小组讨论、安静阅读和大型项目等各种教学活动需求，最大限度地保障灵活性。通过这样的设计，学校不仅为学生提供了一个多元化的学习环境，还为他们的全面发展创造了有利条件，助力打造多元教育生态。

Catering to the diverse learning styles of students, the school offers spaces for gatherings of different scales, quiet areas for focused work, and active spaces for team collaboration. For instance, L-shaped classrooms support zoning and grouping, accommodating various educational activities such as one-on-one learning, group discussions, quiet reading, and large projects, thereby ensuring maximum flexibility. Through such design, River Grove Elementary School not only provides a diversified learning environment but also creates favorable conditions for the comprehensive development of students, fostering a diverse educational ecosystem.

04

为福祉而设计，构建心灵绿洲

在塑造学生全面发展的教育环境中，优先考虑学生的心理健康和福祉至关重要。河谷小学采用分布式的咨询和社会情感支持模式，每个教室都设有窗边角落，为学生提供隐秘和舒适的冷静空间。心理辅导与咨询室位于主办公室外，提供声学隐私，确保学生在心理上得到充分的关爱和支持。此外，学校设计注重自然光与视野的利用，提供可操作的窗户和户外学习区，以增强学生与自然的联系，起到镇静效果。

Prioritizing students' mental health and well-being is crucial in shaping an educational environment that fosters comprehensive development. River Grove adopts a distributed counseling and socio-emotional support model, with each classroom featuring window nooks where students can “chill out.” Counseling and advisory rooms are located outside the main office, offering acoustic privacy to ensure that students receive ample psychological care and support. Additionally, the school's design emphasizes the use of natural light and views, offering operable windows and outdoor learning zones to enhance students' connection with nature, providing a calming effect.

05

连贯空间布局，带来沉浸式社区体验

原有小学由一系列独立建筑组成，通过有顶走道连接。改建后的学校则通过连贯的空间布局，着重培养社区感，提供一个更加紧密和互动的学习环境。中央的双层高入口区可以俯瞰学习庭院、公共区、户外花园、创新实验室和图书馆，进一步增强了空间的连通性和整体感。

The original elementary school comprised a series of separate buildings connected by covered walkways. The renovated River Grove, through a coherent spatial layout, emphasizes fostering a sense of community, providing a more cohesive and interactive learning environment. The central double-height entry zone overlooks the learning courtyard, public areas, outdoor gardens, innovation labs, and the library, further enhancing spatial connectivity and a sense of wholeness.

06

自然连接与融合，实现资源创新循环

研究显示，与自然世界的连接有助于降低血压、改善短期记忆、减少负面情绪并减轻“直接注意力疲劳”。设计过程中，Arcadis凯谛思通过色彩、材料、自然景观和图案等方式为河谷小学提供与自然连接的机会。例如，使用天然木材和橡胶等低挥发性有机化合物（VOC）和可持续产品，不仅为学习环境提供了温暖感，还改善了室内空气质量。分布广泛、多样的户外空间进一步鼓励学生将学习延伸到自然中，促进他们与自然的亲密接触。

Research shows that connection with the natural world helps lower blood pressure, improve short-term memory, reduce negative emotions, and alleviate "directed attention fatigue." During the design process, Arcadis incorporated opportunities for nature connection at River Grove Elementary School through the use of colors, materials, views to nature, and patterns. For example, the use of natural wood and rubber, which are low-VOC and sustainable products, not only provides warmth to the learning environment but also impacts indoor air quality. Extensive and varied outdoor spaces further encourage students to extend their learning into nature, promoting intimate contact with the natural world.

整个学习社区环抱庭院，西眺成熟林地。设计巧妙地保留了大量现存古树作为碳汇，并回收原有学校体育馆的胶合木梁用以制作长凳和“学习树”，赋予其新生，彰显了对自然资源的尊重和循环再利用之美。

The entire learning neighborhood is oriented around a courtyard, facing an existing well-established grove to the west. The design cleverly preserves a significant number of existing ancient trees as carbon sinks and repurposes the glue-laminated timber beams from the original school gymnasium into benches and a "learning tree," giving them new life and showcasing respect for natural resources and the beauty of recycling and reusing.

河谷小学改建项目于2022年6月开工，并已于2024年秋季学期开学时完工。重建后的学校不仅为学生提供了一个安全、健康且富有创造力的学习环境，还将成为其他教育设施的重要榜样，引领教育设计现代化与可持续的新风尚。

The River Grove Elementary School renovation project began in June 2022 and will be completed in time for the start of the fall semester in 2024. The rebuilt River Grove will not only provide students with a safe, healthy, and creative learning environment but will also serve as a significant model for other educational facilities, leading the way in modernizing and sustaining educational design.
