Continuing on to Comilla, Dhaka and the Coast
After finishing fixing their global navigation satellite system equipment in Sylhet, Mike Steckler and his team traveled south to repair more stations in Comilla, then to Dhaka and the coast.
By studying thousands of buildings and analyzing their electricity use, Columbia Climate School Dean Alexis Abramson has been able to uncover ways to significantly cut energy consumption and emissions. Watch the Video: “Engineering a Cooler Future Through Smarter Buildings“
