InventoryAssessment

An inventoryassessmentisrecommendedinordertooptimizesavings andto ensureproperlightinglevelsare achieved.Manyroadwaysare over-litand, assuch, energysavings canresult bysimplyreducinglevelstothe required standards. LEDsoffer improved distributionof lightoverpastluminaires such as HighPressureSodium (HPS).

DesignyourLightingInstallation

When designingalighting installationthreefactorsmustbemet:

Maintained HorizontalAverageIlluminanceorLuminance-Theaverageamountof lightontheroad;

UniformityRatio-Theevenness ofthelighting

VeilingLuminanceRatio-Aratingofglare.

Thesefactors canbeobtained viathe current citylightingstandards andappliedto thevariousroadways.This shouldhelpdeterminewhattheexistinglevels aresupposed tobe,andwheretheymaybedeficientorover- lighted. It mayalsobea goodtimeforacitytoupdatetheir lightingstandardsandpoliciestoreflectcurrent

Lightingrequirements(roadclassificationandpedestrianactivity),roadinformation(widths, numberof lanes, sidewalk info.),polelocations (spacing),heights, andwattages canbe obtained fromthecity’s GIS database. If nodatabaseexiststhen a surveyofexistinglightingcouldbeundertakenusingaerial (Google™)maps and existingelectrical designdrawings. This processcanbesimplified,howeversomeeffortwillberequired.

Calculations

Once thisinformationisobtained, calculations usingcomputerroadwaylightingcalculationsoftwareshouldbe undertaken. Each lightingdesignconsultantwillhavetheir preferred software.

TheSuper-efficient EquipmentandApplianceDeployment(SEAD) initiativeoffers afreeonlinestreetlighting evaluationtool (endorsedbyNRCan)thatcan alsobeused toproperlydefine specificinformationrequired on

roadtypes,polespacing, roadgeometrics, etc. Access theSEADtool.

Step 4– Apply foraConservation and Energy ManagementIncentive

Tosubmit for aBCHydroConservation and Energy Management incentiveapplication,you willneedto:

1. ensurethatyour project meetstheminimum 20,000 kwh/year inelectrical savings;

2. assumingthisthresholdismet,usethelightingenergysavingcalculator(availablethroughyourKey AccountManageroratthetelephonenumbersbelow)andprojectproposal (detailingthecostsfor materials andlabour);and

3. submittoyourBC HydroKeyAccountManager.IfyoudonothaveaKeyAccount Manager, pleasecall

Step 5– Ordering through the CorporateSupplyArrangements(CSAs)

CorporateSupplyArrangementsare “anofferfromthesuccessfulsuppliertoprovidetheGoodsto theProvince andPublicSectorEntities onan as, if andwhen requestedbasis atthepricessetoutintheCSA”.Thismeans that thegoods havemettherequirementsof aspecification and been evaluatedwithinacompetitiveprocess, andareavailablewhen purchasersarereadytopurchasethem(withinthe termof theCSA),attheprices quoted.

Thereisnocontractformeduntil anorderisplaced.Suppliersagreetooffer thegoodsontheterms and conditionsoftheCSA, butthecontractis formed betweenthepurchaser andthesupplier,ratherthanthe Provinceandthesupplier(unlesstheProvinceisthe purchaser). Socontractperformanceandwarrantyissues flowthroughtothe purchaser.
