Think Like a Detective

• Talk to people, get their opinion.

• Be suspicious; don’t believe

everything you hear, see the bills

and the records.

Measure

• Measure where possible, instantaneous or longer period data logging

Always Double Check

• Check different information sources.

• Collect aggregate and detailed data and information, process and compare.

• Sub meter and sub divide loads, study the profiles.

• Allocate consumption by energy type, function, month.

• Create different mathematical models and compare

Diagrams to Visualize

• Draw graphs and diagrams; it will help you to see different perspectives and think outside of the box.

• Put the profile data on graphs and try to read them.

Be Creative

• Tailor the XL sheet for each specific ECM.

• Never play with the engine.

• Use links as much as possible.

• Avoid entering data instead of formulas or links.

• Management vs technology

– Low cost/no cost management measures

– Energy manager must follow energy auditor

• Baseloading

• Part loading use a more efficient equipment for baseload and keep the old equipment for peak load

• 50% + 50% or 70%+30% etc.

Some Hints

Always get a good baseline

Account for double counting

e.g. Lighting ECM, efficient lamps and controls

Downsizing – base-loading

Try alternative technologies

Use Externalities

– Incentives, fines

Use avoided old reinvestment as negative investments

Example: Direct Benefits.

Dynamism of Energy Costs

• а) Energy saving project

• (temporary Energy Management)

• b) СЕМ

• (Constant Energy Management)

PARTIAL PAYBACK (SIR < 1)

• Project may not be feasible (SIR < 1) on pure financial basis.

• Justify part of project on energy savings, rest for other reasons.

• Try analyzing just incremental costs.

CASCADING BENEFITS

• Cascade down for reduced consumption (EE).

• Cascade up for increased supply (RES).

• Avoid overcounting or undercounting.

NON-EXISTENT BASELINE

• Avoid fantasy baselines – no exceptions.

• Analyze ECMs for new construction using “business as usual” baseline.

MANAGEMENT vs. TECHNOLOGY

• Low cost/no cost management measures

• Energy manager must follow energy auditor

BASELOADING

• Save old inefficient equipment for peak loads.

• Understand when old equipment does more harm than good.

INVESTMENT/SAVINGS SCHEDULES

• 0-19 yr - Investments

• 1-20 yr - Savings

EXPECTATIONS

• 1%/measure is good average.

• Collect measures in audit to see total.

EXTERNALITIES

• Only have value in analysis if somebody will pay for them.

PRE-SCREENING

• To produce preliminary analysis, introduce two elements that LCC has but SPB does not: – Cost of capital (discount rate)

– Reinvestment schedule

• Show these two plus initial investment and annual net savings

• State all important assumptions.

• Can perform pre-screening of projects with 10 Steps spreadsheet.
