Researchers at Iowa State University have developed a model to test how shading and air flow can improve indoor temperatures during the sweltering heat of Midwestern summers, reports Iowa State University’s press office. New research lead by ISU associate professor of architecture Ulrike Passe shows the effects of tree shading and evapotranspiration on building temperatures during extreme heat. Passe’s research group Sustainable Cities recently presented their findings at the Comfort at the Extremes 2019 Conference in Dubai.
