Energy  Management  in  Ac/on   Reducing  u*lity  costs     by  op*mizing  opera*ons  
How  important  is  Energy  Efficiency?   •  Buildings  use  20%  of  US  energy.   •  Cement  manufacturing  is  energy-­‐intensive.   •  Energy  efficiency  is  the  answer  
Recent  Int’l  Survey,  2800  respondents     •  56% have invested the same or more in energy efficiency in the last year •  92% said energy management is an important priority •  Top reason for interest in energy management: cost savings  
Energy  Management  Process   1.  Gather  and  analyze  preliminary  data   2.  Inspect  the  facility   3.  Iden*fy  possible  measures  &  explore   feasibility   4.  Report  results
