Purvi Patel

Purvi Patel analyzed the potential of installing cloud-based energy dashboard systems at 600 AT&T locations. After creating a database of discrete asset and system information from individual sites, Patel wrote a strategic plan and site-level processes for installing the dashboards. 

The systems, which would be accessible both onsite and remotely, have the potential to optimize facilities operation and transparency by providing real-time, accessible energy-use feedback. Patel estimates that this could save up to 5 percent of electricity costs and consumption at dashboard-equipped facilities.

Ravindra Bhandari

Ravindra Bhandari spent his summer as an EDF Climate Corps fellow with AT&T in Dallas, TX. He engaged in the ongoing cooling system work that EDF and AT&T are jointly pursuing, looking for opportunities to increase energy, water and chemical efficiency. His work at AT&T focused on improving water efficiency using three approaches.

One, technology - evaluating advanced water treatment technologies, including high efficiency softeners, nano-filtration, pH control and electro-ionization. Two, operations - developing tools and programs to engage facility managers and water treatment vendors to reduce the amount of water needed in cooling towers. Three, free-air cooling - identifying sites where free air cooling can be used, thereby reducing the need for mechanical cooling and the associated load on chillers and cooling towers.

Bhandari worked toward driving implementation of several pilot projects as a means to measure savings and to build a business case for further expansion.
