SHADE AND COOLING DEVICESPage 34In the Valley, people's outdoor decisionmakingrevolves around the intensity ofsunlight and the heat it produces. Ourautomobiles, our back yards, our sportsfacilities and our walking distances tothe market, our schools and the bus aredesigned and organized around ourheat tolerance during any given day. Toignore this very real aspect of life in theValley is to render the transit systemdysfunctional before it opens.Approaches to mitigate the detrimentalaffects of the sun/heat to the ridershipcould include, but will not be limitedto:∆ station shelters and screensdesigned to create shade during keysolar angles,∆ streetscape elements such as trellises,vertical screens, and horizontalscreens,∆ existing buildings or the configurationof new buildings which can beemployed in shadow casting or theinclusion of arcades,∆ unique archetypes such as tents,canopies, or ramadas,∆ materials or configuration of constructionprocesses which employadvanced cooling strategies such astensile fabrics, lath lattices, or perforatedmetals∆ and landscape materials strategicallyplaced throughout the pedestriancirculation and queuing areas.Shade, together with cooling strategies,may be the two most important elementsin regards to the successful functioningand marketing of the system. Inthe desert climate, it is crucial that multiplestrategies be employed to protectthe rider's comfort, including the completionof a sun angle analysis at everystation location and the incorporation ofthe results into station design.Traditional single canopy transit solutionswill not provide the requiredamount of shade without the additionof vertical shade elements, adjacentbuildings, or other shade structures.Urban DesignPerformance Criteria∆ Develop shading systems to assureshaded conditions occur whereverpedestrians / transit users congregatewhile waiting for the train, by:- making use of existing shadedevices such as buildings, architecturalfeatures or trees, and/or- providing appropriately designedand well-sited shade devices.∆ Design vertical shade screens toblend appropriately with stationarchitecture and site the screen so asto fit contextually with adjacentland uses.∆ Provide design solutions that reflectsystem-wide commitment to a progressiveexpression of the community'sspirit.∆ Use shade devices with other elementsto define station area's imagewithin the neighborhood and to celebrateregion's uniqueness.∆ Site vertical sun screens within stationareas to avoid negative impactson adjacent businesses, residences,right of way circulation, and landuses (both current and anticipated).fit within the system aesthetic ofcolor and materials yet take intoconsideration immediate communityidentity and scale, and take extraprecautions so as to not create blindspots or forms that violate CPTEDprinciples.∆ Optimize shading solutions for allsunlit hours in response to the solarorientation from March 21 through
URBAN DESIGN GUIDELINESSeptember 21. For specific sun anglerequirements, see “Climate,Comfort and Health” Report.∆ Create shading system that recognizesprimacy of canopies onStation Platforms.∆ Provide areas of partial shadow inaddition to areas of full shade.∆ Explore opportunities for shadingdevices to interact with pavementand lighting to project changing patternsof light, shadow, and colorimages throughout the day and seasonally.∆ Design shading systems, to theextent possible, to allow solar penetrationto pedestrian areas duringthe winter months.∆ Take advantage of unique opportunitiesfor fully integrated artist/architect/ engineer collaboration.∆ Utilize materials that are low-maintenance,which minimize impact ofdust and wind driven trash, and arerugged under windy conditions.∆ Design shade elements appropriatelyto be vandal resistant and to beinaccessible to climbing.∆ Incorporate cooling devices accordingto the recommendations ofthe”Climate, Comfort and Health”Report.Cost0.8%% of Overall Budget% Urban Design Affects ElementVertical ScreensShade Trees and Shelters100%Importance to User’ sExperienceForm: HighShading elements will be a highly visiblepart of the design vocabulary ofoverall system.Buildings and Architectural FeaturesFunction: HighDevices are critical to enabling /encouraging use of the system duringsummer months.Page 35
