This paper evaluates the adaptive method application proposed by the last version of ASHRAE 55 (2013) standard in two different climates in Brazil. ASHRAE 55 (2013) currently allows for linear and exponential methods to calculate the prevailing mean outdoor air temperature (Tpma(out)) and both are used to establish the acceptability zones. For the exponential method, two different α were used (0.6 and 0.8). Moreover, the Tpma(out) was calculated for two different time spans (7 and 30 days).
