-Using setback during nights for thermostats savings can be up to 10~15% (D.

-1.23 euros per per square foot (National Grid), mean 890 square feet per employee (US EIA), total 1094.7 euros per employee per year without savings+Using the reference figures of 1.23 euros in price per square foot per year (National Grid), the mean of 890 square feet usage per employee (US EIA), gives the of total cost of 1094.7 euros per employee per year without savings.
  
-Possible savings of 109 to 219 euros per year per employee (estimate)+Possible savings should therefore be in the range of 109 to 219 euros (10~20%) per year per employee.
