– Indoor lighting– Outdoor lighting– Process motors– Air conditioning / refrigeration– Heating– Other electrical

• Decide what you want your bill to be next year • Take the steps to get there• Track your progress

CHALLENGES FOR ORGANIZATIONS IN EXECUTING FACILITY ENERGY EFFICIENCY PROJECTS

Lack of understanding of opportunities to reduce operating costs/ carbon emissions

Lack of in-house expertise/ independent analysis

Concern about cost of up-front capital expenditure requirements

Lack of understanding about tax incentives and rebate programs available

Lack of understanding about financing opportunities

Limited number of energy efficiency services solution providers

Lime Energy addresses all of the challenges in executing energy efficiency projects

EXAMPLE ENERGY EFFICIENCY PROJECTFACILITY LIGHTING

SIMPLE ONE FOR ONE REPLACEMENT• No change in light levels• No repositioning• No interaction with other controls• Often a single fixture type

Example Result– Spend $200,000– Save $80,000 per year– 2 ½ year payback

ENGINEERED UPGRADE• Correct light levels for the task• New fixture locations where appropriate• Occupancy/daylight/total building controls• New fixtures to meet new needs• Lighting simulation study

Example Result– Spend $350,000– Save $180,000 per year– 1.9 year payback

TWO PATHS TO FOLLOW

The Engineered Upgrade saves $100,000 more per year(Equals additional profits from $3 million in new sales)

EXAMPLE ENERGY EFFICIENCY PROJECTFACILITY LIGHTING

SIMPLE LIGHTING CHANGE OUT

• May overlook the best utility rebates• May overlook the latest tax treatment• May overlook the opportunity to

redesign• May overlook the latest technology, or

spend too long researching

ENGINEERED SOLUTION

• Up on the latest technology, tried and proven

• Maximize utility rebates• Maximize tax benefits• May offer several options for redesign,

each with superior financials• Be sure to choose a qualified resource

TWO PATHS TO FOLLOW

THIS GETS EVEN MORE COMPLICATED WHEN YOU GO BEYOND LIGHTING.
