Keys

• Save energy

• Lower utility operating costs

• Maintain or improve operations

• Support corporate goals

ANSI Std MSE 2000:2005

Role of Energy Mgr

Recommended Process

• Achieve savings without capital outlay

• Establish benchmarks and budgets

• Collaborate with other departments

Utility Tracking

• Track utility bills each month and establish normal pattern for process/property for each type of utility

• Check utility meters in the field for correlation to what Accounting is paying on the utility bills.

• Digitize utility bills for ease of retrieval when researching potential savings opportunities

• Establish Utility Analyst in Accounting if you have many properties and accounts

Most Common Problems• VFD’s that don’t modulate,

• controls out of calibration,

• static pressure higher than required,

• night setbacks not implemented,

• equipment operating more than necessary or inefficiently,

• EMCS never programmed,

• improper sequence of operation,

• simultaneous heating and cooling,

• outside air damper settings/economizer controls.

Types of Audits and Costs
