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
