The project started last year and has enrolled 61 households so far, with a goal of eventually reaching 120 homes. For now, the study is only enrolling Clayton, Cobb, DeKalb, Fulton and Gwinnett county residents, like Tessa Horehled.<\/p>\n
Horehled lives in a 100-year old home in Westview, a few miles west of downtown Atlanta, and has asthma, a condition that can be exacerbated by extreme heat and poor air quality<\/a>. With an infant at home, too, she said she decided to participate to understand her \u201cbaseline\u201d exposure. <\/p>\n The project started last year and has enrolled 61 households so far, with a goal of eventually reaching 120 homes.

Inside, they had Horehled place another monitor in her bedroom. Combined, the heat and humidity readings are used to calculate the heat index<\/a>, Saikawa said, a measure of what it actually feels like inside and outside the home. <\/p>\n \u201cWe have a lot of data on the ambient temperature, but we don\u2019t really know what\u2019s indoor and what\u2019s personal,\u201d said Saikawa, the project\u2019s lead researcher. \u201cAnd for extreme heat, personal exposure is very important.\u201d <\/p>\n On a Tuesday in August, Emory environmental science professor Eri Saikawa and public health associate Jiyoung Hwang, installed sensors at Horehled\u2019s home to begin gathering data.<\/p>\n
