Process Efficiency Policies

Process efficiency policies include building energy efficiency improvements in residential, commercial, and industrial sectors and modifying vehicle miles traveled per person in transportation.


Process Efficiency Policy Variables

To create a process efficiency policy, modify one or more of the variables listed in the table below. 


Policy variables consist of variables that will impact process efficiency directly.


Additional variables may be assigned values to reflect the costs of obtaining the improved energy efficiency. Note that applying a standard without adjusting other curve parameters will generally result in an increase in endogenous investment levels from the model.


Policy Variables

Direct Impact

PEMM[Enduse,Tech,EC,Area,Year]

Process Efficiency Maximum Multiplier ($/Btu/($/Btu)

Adjusts the process efficiency curve up or down

PEStdP[Enduse,Tech,EC,Area,Year] 

Process Efficiency Standards Policy (($/Btu)/($/Btu))

Sets a floor for efficiency levels

Additional Variables

Direct Impact

PInvExo[Enduse,Tech,EC,Area,Year] 

Exogenous Process Investments ($/Btu)

Adjusts investments to account for cost of the program


Sample Code

  areas = Select(Area,"BC")

  for area in areas

      

    years = collect(Yr(2026):Yr(2030))

    for year in years

        EEImprovement[area,year] = 0.419

    end
