Case Studies

A Fortune 500 IT company was keen on cutting down on its operational expenses within its office. Lighting was identified as one area where considerable savings was envisaged. After visiting their office and analyzing the lighting we found several defeciencies. It was not necessary to have lighting in all the nooks and corners of the lobby area. It was not required to have power hungry bright lights in the corridor area. The rest rooms needed lighting only when being used. The total energy consumption was a steep 350,000 KW/year. With the electricity costs standing at Rs.5/unit the total cost was Rs.1,750,000.

Upon our recommendation the CFL bulbs were replaced by LED lights. The lobby was lit up by soft lights only in the required areas. In the corridor dim lights were used. In the rest rooms intelligent lighting system was installed. When not in use these would be dimmed completely. The power consumption now is 73,000 and the electricity bill at Rs. 365,000 came down by 80%. Everyone in the office admired the visual appeal created by the new lights.

A global retailing firm was looking at rationalizing operational expenses inside its offices. We visited one of its offices, a huge one, and analyzed the lighting in different areas like lobby, corridor, rest rooms, pantry, path ways etc. This office operated throughout the night and hence it was required that lights in the common areas be kept on throughout the night. The power consumption stood at a high value of 214,445 KWh/year. We concluded that there was a huge potential for savings by using LED lights.

The existing CFL lights were replaced by Innovlite LED lights. With this the power consumption reduced drastically to 60,045 KWh/year resulting in the firm achieving a savings of 68% on internal lighting expenses. While using only as much energy as required the new lighting looked simply beautiful.
