項目簡介

休梅克綠地總共占地2.75英畝，緊靠第33街東面，位于沃爾納特街與斯普魯斯兩條街道之間。該項目將荒廢已久的網(wǎng)球場和幾條狹窄的通道以及具有歷史意義的戰(zhàn)爭紀念碑景點組成的場地改造為費城西部地區(qū)的公共綠化空間設施。該設計借鑒了賓夕法尼亞大學傳統(tǒng)校園綠地的特點，營造出一種似曾相識的視覺，同時將緊鄰的各建筑入口、人行道、路緣石和陡峭斜坡階梯進行了整合。整塊綠地是賓夕法尼亞大學東西方向主體步行系統(tǒng)的重要組成部分，它將校園中心區(qū)與田徑運動場連接起來，同時也是賓夕法尼亞大學校區(qū)向東擴建的重點區(qū)域。在該場地的邊緣是賓夕法尼亞大學最具標志性的體育設施：菲爾德豪斯體育場和富蘭克林運動場，休梅克綠地成為了這兩大歷史性建筑設施的前庭空間。該項目為可持續(xù)性校園設計樹立了標桿，同時獲得了可持續(xù)場地倡議組織的二星榮譽。

該綠地由中央半圓形草坪和一個大型雨水花園組成，其邊緣是由精細石材修筑而成的擋土墻和幾條雅致曲折的人行道所環(huán)繞。通過對賓夕法尼亞大學傳統(tǒng)景觀材料及設計方法的延用，這塊綠地自然地融入到原有校園環(huán)境系統(tǒng)中，使之具有現(xiàn)代感，并且實現(xiàn)了有效擴展。大型多層花崗巖坐墻為綠地提供了坐歇設施，綠地上種植著幾株刺槐樹，為在此休息的人們平添了幾分舒適與愜意。其間擺放地咖啡桌椅和具有賓夕法尼亞大學校園特色休閑長椅，為人們提供了一個靈活的多功能公共聚集空間。高效節(jié)能的照明設計為休梅克綠地的夜間安全提供了保障，在這些柔和燈光的照射下，校園中的歷史建筑別有一番韻味，提升了整個綠地空間的文化及歷史內(nèi)含。

 

場地分析

在項目設計之初，設計師們便對項目場地狀況進行了深入地評估，以對整個場地空間的歷史背景、環(huán)境現(xiàn)狀、生態(tài)結(jié)構(gòu)以及功能性做出系統(tǒng)的了解。場地的設計對綠地使用者需求與喜好非常在意，以賓夕法尼亞人長期以來對于自然的欣賞和他們的需求及偏好為出發(fā)點。因而，一個由賓夕法尼亞大學代表、費城相關機構(gòu)代表和設計團隊代表組成的多方利益團體應運而生，對整個項目設計過程進行嚴格監(jiān)督和審查，最終形成了全面完美的設計方案。

 

場地規(guī)劃

休梅克綠地主要是迎合休閑娛樂需求，并能夠同時容納多種校園活動的舉辦。作為校園田徑運動場核心區(qū)的全新開放公共空間，休梅克綠地還需具備諸多前所未有的綜合性功用。綠地空間投入使用后，可支持各種規(guī)模的活動的舉辦，包括一些重大的校內(nèi)活動，比如：畢業(yè)典禮、大型集會以及賓州接力賽等國際性比賽，同時也可作為戶外課堂、播放夜晚露天電影、舉辦音樂會和展覽會等。

 

過渡空間

在斯庫基爾河沿岸賓夕法尼亞大學校園區(qū)域連接總體規(guī)劃中，休梅克綠地成為了校園中央古老建筑結(jié)構(gòu)與更為現(xiàn)代的新型時尚開放空間之間的一個過渡。該綠地繼續(xù)秉承原有的刺槐/史密斯步行道的設計特點，并同時吸納了賓夕法尼亞大學傳統(tǒng)的校園綠化景觀元素，同時融入了新的設計元素，這些都反映了可持續(xù)發(fā)展及生態(tài)景觀設計的重要性。

 

系統(tǒng)化的設計思路

休梅克綠地創(chuàng)造了一個多功能的校園景觀空間，它不僅提供了良好的生態(tài)系統(tǒng)服務功能，而且還滿足了賓夕法尼亞大學提出的相關計劃要求。該綠地的功能化運行如同人的腎臟，通過一個綜合性景觀系統(tǒng)，收集了整個場地95%的雨水量，對雨水進行傳送、過濾及存儲，之后可以用于灌溉。其余的水源需求則依靠毗鄰建筑的屋頂雨水徑流及空調(diào)冷凝水。

休梅克綠地的設計源于一種系統(tǒng)化的設計思路，即將自然生態(tài)系統(tǒng)（土壤、植物、昆蟲、鳥類和人類）與人工營造的系統(tǒng)（建筑構(gòu)件和基礎設施）整合成為一個功能性的整體。該設計采取雙管齊下的有效方法來管理場地內(nèi)的雨水。其首要策略就是將雨水徑流傳送至一個包含經(jīng)過設計的土壤層和多種原生植物的大型雙層雨水花園中，目的是對大量的雨水進行治理、過濾、蓄存，然后最終排出用于灌溉；另一個方法就是從該場地及相鄰建筑中收集雨水徑流和空調(diào)冷凝水，并將其釋放到主體綠地下方的土壤層中。這些水源在經(jīng)過土壤層時被有效過濾，然后滲入到綠地以下幾英尺深的大型蓄水臺中。原有網(wǎng)球場中的很大一部分得以留存，并置于現(xiàn)有綠地下方，以支持地下循環(huán)蓄水臺的運轉(zhuǎn)。沒有流經(jīng)土壤層和原生植物的多余水資源經(jīng)由地下排水系統(tǒng)采集，之后被傳送到另一個大型蓄水池中進行蓄存，并得以循環(huán)再利用。一旦整個系統(tǒng)處于滿負荷運作狀態(tài)，則大量雨水將溢流入原有的市政下水道設施中，以避免嚴重積水。

在施工過程中，所有之前用過的材料都得以充分回收或升級再造。通過培訓項目承包商們了解了安裝非傳統(tǒng)雨水基礎設施的相應方法；確切地說，他們是了解了雨水處理設施與土壤及植栽材料協(xié)同作用的重要性。具體的施工協(xié)調(diào)和測序?qū)τ谠擁椖砍晒κ┬惺鞘�分重要的。費城水利部門和可持續(xù)場地倡議組織都對該項目進行了嚴格檢測，并要求對項目文檔進行詳盡編制。

 

場地監(jiān)測

休梅克綠地已成為罕見的綠色基礎設施典范，究其原因，它是一個經(jīng)過嚴格檢測的高效能景觀項目，可以將水源進行回收、過濾，并有效地將清潔的水資源重新回流到環(huán)境中。一份歷時五年的監(jiān)測規(guī)劃的制定，最終使得景觀建筑師、賓夕法尼亞大學教職員工及學生，以及廣大公眾都有機會共同參與到這一真正意義上的“生態(tài)景觀系統(tǒng)”中去。該項目的景觀設計師們與賓夕法尼亞大學教職員工及學生代表共同對以下幾個方面做了積極而深入的監(jiān)測——項目場地進出雨水的數(shù)量和質(zhì)量；對項目系統(tǒng)程式化運作起到支持性作用的土壤的生物性質(zhì)、多樣性、演變過程、碳穩(wěn)固性、養(yǎng)分循環(huán)以及土質(zhì)本身；植栽材料的健康狀況（即生長與根部發(fā)育狀況）及其對土壤水分的蒸散量；灌溉水源獲取及再利用系統(tǒng)的運行性能及效率；人們對該綠地使用頻率的跟蹤監(jiān)測；生態(tài)關聯(lián)性和人們對于綠地景觀的感知與體驗——從而將促成賓夕法尼亞大學關于綠化環(huán)境維系方面的長久性校規(guī)的出臺。對于項目場地性能的精心設計與持續(xù)性監(jiān)測將有助于未來大學校園的景觀設計，同時也有助于對美國國家可持續(xù)性景觀設計指南和建筑規(guī)范的修訂產(chǎn)生積極的影響。

Introduction

Shoemaker Green is a 2.75-acre site located immediately east of 33rd Street between Walnut and Spruce Streets. The project transformed an existing site with aging tennis courts, narrow pathways, and obstructed views of a historic War Memorial into a cherished public amenity for West Philadelphia. The design draws on the character of Penn’s College Green to create a familiar feel while seamlessly integrating adjacent building entrances, pathways, curbs, and steps across a steeply sloping site. The completed green is a vital component of the University of Pennsylvania’s primary east-west pedestrian system, connecting the central campus to the athletics precinct, and serving as the focal point of Penn’s eastward expansion. The site is bordered by the University’s most iconic athletic facilities, the Palestra Fieldhouse and Franklin Field, and serves as the “front yard” to these historic structures. The project sets a benchmark for sustainable campus design, earning two-stars from the Sustainable Sites Initiative (SITES™).

The green is organized around a central, semicircular lawn and a large rain garden, bordered by precisely-detailed stone retaining walls and elegantly-graded pathways. The green integrates with and extends the existing campus circulation system by utilizing the University’s landscape standard materials and treatments, but with a modern sensibility. Seating is provided by large, multi-leveled granite seat walls, welcoming visitors with comfortable Black Locust wood insets. Café tables and chairs, as well as free-standing benches typical of the Penn campus, offer flexible gathering spaces throughout the site. High-efficiency lighting provides safety at night, while heightening the sense of place by beautifully illuminating the historic architecture.

 

Site Analysis

The design of Shoemaker Green began with an in-depth site assessment to methodically review and understand the space’s history, context, ecological structure, and functional capacity. The design was sensitive to the needs and requirements of site users, born of a long appreciation of the nature of Penn’s population and their needs and preferences over the hours and seasons that the green would be occupied. A diverse stakeholder group, including representatives from within the University, Philadelphia agencies, and the design community, refined the final design through a rigorous design review process.

 

Site Program

Shoemaker Green caters to a program of mainly passive recreation, but the site can adapt to accommodate events and activities at multiple scales. This park has met the demand for new open space in the historic athletics precinct to host a myriad of uses, many of which had not previously existed on campus. The green now graciously supports a wide range of different-sized events, including large, key campus moments such as graduation and convocation, international events like the Penn Relays, and new programming such as outdoor classrooms, movie nights, concerts, and fairs.

 

Transitional Space

Shoemaker Green provides a transition from the historic fabric at the core of campus to the more contemporary new open space developments of the PennConnects Master Plan along the Schuylkill River. The green continues the Locust Walk/Smith Walk corridor, referencing landscape elements of Penn’s historic College Green while introducing new design elements that reflect the importance of sustainability and ecologically sensitive landscape design.

 

Systems-Based Thinking

Shoemaker Green has created a functional landscape that provides eco-system services in addition to satisfying the programmatic requirements set forth by the University. The site functions much like a kidney capturing ninety-five percent of the site’s rainwater through an integrated landscape system that includes the conveyance, filtering, and storage of stormwater for reuse as irrigation. Additional water is provided from roof runoff and air conditioning condensate from the adjacent buildings.

The design of Shoemaker Green stems from a systems-based thinking that integrates natural systems (soils, plants, insects, birds and human beings) with man-made systems (building components and infrastructure) to function as a whole. The design has a two-pronged approach to manage the site’s stormwater. The first strategy is to convey stormwater runoff to a large, two-tiered rain garden that contains designed soils and native plant species to manage, filter, store, and transpire a significant amount of stormwater. A second approach is to collect stormwater runoff from the site, as well as runoff from the roof and condensate from adjacent buildings, and release the water into the soil under the main green. This water is cleaned while percolating through the designed soils as it makes its way to a large storage bed several feet below the green. A large portion of the existing tennis courts were left in-place under the main green to support a recycled aggregate storage bed. Any excess water that is not taken up by the soils and plants is captured in this bed through an underdrainage system and conveyed to a large cistern and stored for reuse. Once the entire system reaches full capacity, very large storms overflow to the existing municipal sewer line preventing flooding.

During construction, all existing materials were recycled or upcycled. Contractors were educated about installing non-traditional stormwater infrastructure; specifically, the importance of working with soils and plant material. Detailed coordination of construction activities and sequencing was paramount to the importance of the successful implementation of this project. Stringent testing and documentation were required by both the Philadelphia Water Department and SITES™.

 

Site Monitoring

Shoemaker Green has become what green infrastructure seldom is: a monitored, high-performance landscape that captures, filters, and effectively delivers clean water back to the environment. A five-year monitoring plan has been developed to allow landscape architects, University of Pennsylvania faculty, students and staff, and the general public to interact with a truly “living system.” The following aspects of the project are being actively monitored by the project landscape architects, faculty, and students, and will shape University policy for years to come: Stormwater quantity and quality entering and exiting the site; Soil biology, diversity, evolution, carbon sequestration, nutrient cycling, and capacity to support programmed activities; Robustness (growth and root development) and evapotranspiration rates of the plant material; Performance and efficiency of the irrigation capture and reuse system; Behavior mapping to track people’s use of the site; and, Biophilic connections and people’s perception and experience of the green. The design and ongoing monitoring of site performance will help inform future University landscape design and help influence national sustainable landscape guidelines and building codes.
