位于俄勒岡州波特蘭郊區(qū)萊克奧斯威戈（Lake Oswego）的河谷小學（River Grove Elementary School）近日完成了全新升級改造。此次改造由Arcadis凱諦思負責，秉承現(xiàn)代化和可持續(xù)發(fā)展的設計理念，全面提升了學校的功能與設施強度。

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.

該校原址始建于1967年，占地6,400平方米。改造后，占地面積擴展至約7,300平方米，并成為美國首批配備微電網(wǎng)系統(tǒng)的學校之一。

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.

在抗災能力方面，河谷小學采用了更高的抗震標準，能夠在地震等自然災害發(fā)生時為當?shù)鼐用裉峁┩晟频姆罏谋茈U能力，從而成為重要的社區(qū)資源。憑借全電氣化設計和突出的抗災能力，改建后的河谷小學不僅在能源自主和災害應對方面取得了顯著進步，也以其前瞻性樹立了未來教育建筑的新標準。

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

綠色節(jié)能轉型，可持續(xù)設計新示范

河谷小學采用高效的風冷式冷水機組為教室降溫，確保學生在舒適環(huán)境中專注學習。建筑的機械通風系統(tǒng)配備高MERV等級的過濾器，輸送100%的外部空氣，有效提升空氣質量并應對季節(jié)性野火引起的大氣煙霧問題。此外，熱回收通風（HRV）系統(tǒng)通過從排出的廢氣中回收熱量，減少冬季供暖的能源消耗和運營成本。

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.

學校還采用自動調光照明技術，根據(jù)自然光水平調節(jié)室內(nèi)亮度，降低能耗的同時確保舒適的學習光照環(huán)境。太陽能涂層和外部遮陽裝置則幫助減少窗戶的熱負荷，從而降低冷卻需求并控制教室內(nèi)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.

02

創(chuàng)新微電網(wǎng)系統(tǒng)，社區(qū)韌性全升級

河谷小學配備了一個獨立于區(qū)域電網(wǎng)運行的微電網(wǎng)系統(tǒng)。學校屋頂安裝的150kW光伏（PV）陣列每年可產(chǎn)生相當于建筑年能耗10%的電力。作為微電網(wǎng)系統(tǒng)的“大腦”，可編程微電網(wǎng)控制器在電力中斷時會自動切換到“孤島模式（Island Mode）”，保持系統(tǒng)的穩(wěn)定運行；還可以將未使用的多余光伏能量存儲在電池儲能系統(tǒng)（BESS）中，以削減公用電網(wǎng)負荷高峰時的電力需求，從而增強電網(wǎng)韌性并最大限度地減少碳排放。

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.

通過結合使用BESS和發(fā)電機電力，河谷小學可在停電期間為公共區(qū)和體育館的暖通空調（HVAC）、電氣、技術和管道系統(tǒng)提供應急電力，確保持續(xù)運行。這一設計不僅在自然災害或長期大范圍停電期間為社區(qū)提供重要服務，提升了學校的應急響應能力，也為社區(qū)的整體韌性建設做出了重要貢獻。

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

全維度學習空間，打造多元教育生態(tài)

河谷小學作為一所先進的教育設施，其設計旨在滿足每一位學習者的需求，提供多種教育和活動空間，包括教室、擴展學習區(qū)、創(chuàng)新實驗室、音樂室、展示舞臺、圖書館、行政辦公室、體育館、廚房、半室外活動區(qū)、戶外學習空間和運動場。

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.

針對學生的多樣化學習方式，學校提供了適合不同規(guī)模集會的活動空間、專注工作的安靜空間，以及團隊協(xié)作的活躍空間。例如，L型教室設計提供分區(qū)和分組支持，能夠滿足一對一學習、小組討論、安靜閱讀和大型項目等各種教學活動需求，最大限度地保障靈活性。通過這樣的設計，學校不僅為學生提供了一個多元化的學習環(huán)境，還為他們的全面發(fā)展創(chuàng)造了有利條件，助力打造多元教育生態(tài)。

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

為福祉而設計，構建心靈綠洲

在塑造學生全面發(fā)展的教育環(huán)境中，優(yōu)先考慮學生的心理健康和福祉至關重要。河谷小學采用分布式的咨詢和社會情感支持模式，每個教室都設有窗邊角落，為學生提供隱秘和舒適的冷靜空間。心理輔導與咨詢室位于主辦公室外，提供聲學隱私，確保學生在心理上得到充分的關愛和支持。此外，學校設計注重自然光與視野的利用，提供可操作的窗戶和戶外學習區(qū)，以增強學生與自然的聯(lián)系，起到鎮(zhèn)靜效果。

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

連貫空間布局，帶來沉浸式社區(qū)體驗

原有小學由一系列獨立建筑組成，通過有頂走道連接。改建后的學校則通過連貫的空間布局，著重培養(yǎng)社區(qū)感，提供一個更加緊密和互動的學習環(huán)境。中央的雙層高入口區(qū)可以俯瞰學習庭院、公共區(qū)、戶外花園、創(chuàng)新實驗室和圖書館，進一步增強了空間的連通性和整體感。

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

自然連接與融合，實現(xiàn)資源創(chuàng)新循環(huán)

研究顯示，與自然世界的連接有助于降低血壓、改善短期記憶、減少負面情緒并減輕“直接注意力疲勞”。設計過程中，Arcadis凱諦思通過色彩、材料、自然景觀和圖案等方式為河谷小學提供與自然連接的機會。例如，使用天然木材和橡膠等低揮發(fā)性有機化合物（VOC）和可持續(xù)產(chǎn)品，不僅為學習環(huán)境提供了溫暖感，還改善了室內(nèi)空氣質量。分布廣泛、多樣的戶外空間進一步鼓勵學生將學習延伸到自然中，促進他們與自然的親密接觸。

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.

整個學習社區(qū)環(huán)抱庭院，西眺成熟林地。設計巧妙地保留了大量現(xiàn)存古樹作為碳匯，并回收原有學校體育館的膠合木梁用以制作長凳和“學習樹”，賦予其新生，彰顯了對自然資源的尊重和循環(huán)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.

河谷小學改建項目于2022年6月開工，并已于2024年秋季學期開學時完工。重建后的學校不僅為學生提供了一個安全、健康且富有創(chuàng)造力的學習環(huán)境，還將成為其他教育設施的重要榜樣，引領教育設計現(xiàn)代化與可持續(xù)的新風尚。

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.
