Energy  Effec*veness:  The  Real-­‐World  Benefits  of  BEMS  

https://www.trendcontrols.com/en-GB/Pages/default.aspx

Large  organisa*ons  can  gain  numerous  benefits  from  efficient  Building  Energy  Management  Systems  (BEMS),  from  reduced  CO2  emissions  to  lower  energy  costs.      But  in  the  real  world,  what  specific  advantages  

can  companies  expect?      

Jaguar  Land  Rover  provides  a  real-­‐world  case  example  of  how  a  well-­‐run  and  con*nually  maintained    BEMS  can  make  a  significant  and  transforma*ve  difference.

The  Results  of  BEMS  Enhancement?  

What  were  the  real-­‐world  results  of  Jaguar  Land  Rover’s  enhanced  BEMS?          

What  were  the  real-­‐world  results  of  Jaguar  Land  Rover’s  enhanced  BEMS?    •  A  21%  reduc*on  in  opera*onal  CO2  emissions  since  2007    

What  were  the  real-­‐world  results  of  Jaguar  Land  Rover’s  enhanced  BEMS?    •  A  21%  reduc*on  in  opera*onal  CO2  emissions  since  2007    •  Cost  savings  the  equivalent  of  4,271,544kWh  and  1,67  

tonnes  of  CO2.

   Regular  reviews  allowed  Trend  and  Jaguar  Land  Rover  to  iden*fy  and  recommend  addi*onal  enhancements  outside  of  outside  of  rou*ne  maintenance  expecta*ons.    This  totalled  a  further  3,476,742kWh  and  1,291  tonnes  of  addi*onal  CO2  saved.    

Ongoing  Improvement  For  Con?nuous  Benefit  

With  more  than  26  BEMS  enabled  buildings,  Jaguar  Land  Rover’s  vast  estate  meant  even  a  slight  energy  efficiency  enhancement,  makes  a  drama*c  difference.

Maintaining  High  Standards  

It’s  important  to  remember,  an  effec*ve  BEMS  will  become  inefficient  if  long-­‐term,  progressive  maintenance  and  improvement  strategies  are  forgo`en.  

It’s  important  to  remember,  an  effec*ve  BEMS  will  become  inefficient  if  long-­‐term,  progressive  maintenance  and  improvement  strategies  are  forgo`en.    Annual  reviews  are  necessary  to  track  how  effec*ve  a  BEMS  is  in  the  long  term  and  ensure  the  requirements  of  the  changing  demands  of  the  site  are  met.  

What  Causes  A  BEMS  to  Become  Inefficient?
