  • It involved many complex mathematical calculations for displaying energy savings in terms of Trees Saved Per Year, Cars Removed Per Year, Carbon Reduced Per Year (KG) and Carbon Reduced Per Year (LB)
  • Handling multiple currency and multiple regions


  • It allows Sales / marketing representatives to create the project (commercial office or residential house etc.),
  • It accepts the detail for each room and lights in each room.
  • Select the corresponding new light configured in the database against the existing light.
  • Calculate the energy savings and the cost savings by replacing the old lights with the new lights.
  • The energy savings is in terms of carbon reduction.
  • The cost saving is calculated in terms of replacement cost vs. savings for 52 weeks and savings for 4 years.
