The process of identifying energy efficiency and energy conservation measures (ECMs) relies on the following three step strategy.  This strategy is applied to optimize and fully capitalize on the associated savings and emphasis on reduction of waste:

Minimize Building Loads: Improve the building envelope, reduce lighting power densities and usage, incorporate suitable day lighting techniques, reduce equipment power densities and usage, and reduce water consumption flow rates.

Improve System Effectiveness: Improve HVAC system design, increase motor efficiencies, utilize solar heating technologies, incorporate energy recovery technologies, and utilize applicable controls strategies.

Optimize Resource Delivery: Provide Renewable energy generation, distributed generation, incorporate energy storage techniques, increase the efficiency of the plant, review utility rate options, and investigate district heating and cooling options.
