Infosys’ participation in Daylight Hour required integrated communication across 11 campuses serving more than 150,000 staff and employees. Infosys worked extensively to engage its employees for the Daylight Hour. They began by disseminating information internally through various media, such as mailers, internal radio announcements, and the online employee portal. During Daylight Hour, volunteers were stationed on every floor of each building, and were responsible for communicating the significance of the campaign to employees and ensuring that lights were turned off.
Given Infosys’ focus on data, it should not come as a surprise that throughout Daylight Hour, experts at Infosys’ Bangalore office monitored the lighting energy consumption of participating buildings from their central command center. System level sub-metering allowed Infosys to monitor the impact of the campaign in real time and witness lighting energy consumption drop drastically during Daylight Hour. Nearly a 4% savings in energy (over 1,500 kWh) was achieved in just one hour. This was a clear example of the power of monitoring and management to reduce energy use even in very efficient buildings.
The benefits of day-lit offices on energy use, environmental impact, occupant health, and comfort should not be underestimated. Raising awareness through internal communications and coordination between multiple teams was instrumental in making Daylight Hour a success at Infosys. They utilized the initiative to save money and energy and to educate their employees about the power of daylight. Perhaps more importantly, Daylight Hour was a vehicle for the community to connect with a tangible example of building energy use and to lead them to consider other ways to lower their carbon footprint. Infosys’ participation in Daylight Hour demonstrates that with proper preparation, commitment, and leadership, this initiative has the power to minimize energy use substantially, educate the public, and spark a cultural change in a community.
