Comparisons using web-based Libshuff and Unifrac significance analyses were conducted between the individual buildings and the four seasons. ΔCXY – and ΔCYX – values represent the difference between the two libraries calculated by Libshuff. Libraries that are significantly different with a confidence of 95% are marked with*. 1, Building 1; 2, Building 2; W, winter; Sp, spring; Su, summer; F, fall.
