ERP Custom - Guidelines
Boundaries
Financial
• Buildings must be
served by Stanford
utilities
• Energy saving
projects/components
ONLY
• Does not cover
maintenance/repairs
• < $50,000
• Requires 5 year
payback
• > 5 yr allowed with
cost sharing
• First come, first
served
• Annual budget
funded through rates
($700K for FY12)
• Rebate is cost
capped
S T A N F O R D U N I V E R S I T Y • S U S T A I N A B L E I T • Page 4
Accounting/Process
• Works like rebate
• Groups fund the
project
• ERP comes at back
end through journal
transfer
• Yearly disbursement
• Submit invoices for
journal before fiscal
year close

• Departments identify projects; calculate savings and
payback
• Submit funding request to ERP program manager
• ERP program manager reviews requests, savings and
priorities
• Email ERP $$ committed, assign project #, add to tracking
• Project managers get bids, manage cost, schedule
• Schedule post inspection, submit invoices, get rebate
