When window films were added to make a refugee hospital in Amman, Jordan, the rooms became cooler and more energy efficient, according to an article on the National Geographic website.
Electrician Bryan Garcia was sent by Doctors Without Borders to help the hospital in spring 2016.
Energy demands were growing at the 25-year-old hospital that was reopened in the fall of 2015.
The hospital had bright fluorescent lighting and the air conditioning was taxed by the intense sunlight. Monthly energy bills could run as high as $65,000. Garcia's job was to figure out how to make improvements without disrupting the hospital's operations, the article said.
