Energyefficiencyinbuildingsisclearlyapressingissue.Globally,buildingsareresponsibleforaboutone-thirdoftheworld’senergyuse.Notonlydobuildings use more energy than any other industry, buttheirshareofenergyuseisexpectedtogrowever-moreintense.Numerousstudieshaveproventhatsimpleactssuchascommissioningabuildingorinstallingmoreefficientlightbulbsnotonlysaveresourcesbutalsopayforthemselvesinarelativelyshorttimeperiod.However,manyofficebuildingsintheUnitedStateshavenotevenimplementedsimpleretrofits,letalonemorecomplexandexpensiveretrofits.

All such costs, including interest costs, shall be amortized over the reasonable life of the capital investment items, with the reasonable life and amortization schedule being determined by the landlord according to generally accepted accounting principles, but in no event to extend beyond the reasonable useful life of the building.
Managersareencouragedtocheckwiththeirlegalstaffontheinterpretationofthisclause.
Rebates: Inrecentyears,localutilitycompaniesandmunicipalitieshavebeenofferingrebatestobuildingownerstomakeenergyefficiencyimprovementstotheirproperties.Thepresenceofrebateswasfrequentlycitedasamajorfinancialconsiderationwhendecidingwhetherornottomakeinvestmentsinenergyefficiency.One national manager stated that he would makeinvestmentsinrenewableenergy(mostlyphotovoltaic),butthattheseinvestmentswerebeingmadeonlyinstatesthatprovidedrebates.Alongsimilarlines,adirectoratapropertymanagementfirmillustratedthispointwithalightingretrofitprojectthatcost$1.80persq.ft.($19.38persquaremeter)(USdollars)butwasmorethanpaidforby$2.00persq.ft.($21.52persquaremeter)(USdollars)inrebates.

4 .3 .2 Education and Proof of Concept Is Required
Arecurringperceptionfromtheintervieweesregardingenergyefficiencyretrofitsisthatmanyimprovementsrequiretheuseofnewtechnologiesthatarenotyetproven.Thecasecanalsobemadethatthetechnologiesareactuallywell-proven;ratheritisthecertaintyofreturnsfromthosetechnologiesthatisunproven.Regardlessofwhetherthetechnologiesareunprovenorthefinancialreturnsfromthetechnologiesareunproven,hesitationfromrealestatemanagersexists.Inaperiodwhereinvestmentcapitalisscarce,projectsthataremorevisible,suchasaestheticimprovementstoaproperty,areselectedoverenergyefficiencyprojects.
Asenergyefficiencyimprovementsarefurtherproventoreduceexpensesandcreateapositivereturnoninvestment,adoptionoftheseimprovementscanbeexpectedtobecomemoremainstream.Asthequantitativeanalysishasshown,energyefficiencyprojectshavetheadded

4.3.3 Proper Valuation of Energy Efficiency Improvements Is Needed
Propervaluationofenergyefficiencyimprovementsislackingintherealestateinvestmentmarket.Intervieweesweresplitroughlyequalbetweenthosewhobelieveenergyefficiencyretrofitsareacapitalexpenseandthosewhorecognizethattheseretrofitscanbe aprofitableinvestment.Assuch,anoftencitedreasonformakinginvestmentsinenergyefficiencyimprovementprojectsistodecreaseoperatingexpensestherebyincreasingtheNOItoabuilding.ArelatedreasonforenergyefficiencyinvestmentisthatbuildingswithimprovementsareviewedtohavepotentiallyincreasedNOIinthefuture;therefore,alowersalescaprateshouldbeconsideredwhencapitalizingNOItoapurchaseprice.However,buyers and sellers should not count on realizing both of these effects at the same time.
