Thermal Performance Assessment Occupants in residential buildings have a comprehensive flexibility to adjust their clothing and activities , as well as carrying out actions such as opening and closing windows to regulate natural ventilation , which allow them to feel comfortable . In this context and also aiming to promote energy conservation , the Adaptive Comfort Standard ( ACS ) from ASHRAE-55 was used to establish the neutral temperature and comfort limits for the region under this study . Results from a field study ( Figueroa-Villamar et al . 2014 ) conducted in a very similar context and similar buildings , validated the use of the Adaptive Comfort Standard ( ACS ). The neutral temperature ( Tn ) and comfort zone for each monitored season were calculated using ACS , the thermal boundaries were defined for 90 % of occupant acceptability at 5 K ( 2.5 ° C on either side of the neutral temperature ) and for 80 % of occupant acceptability at 7 K ( 3.5 ° C on either side of the neutral temperature ). For relative humidity a range between 30 % and 80 % is still acceptable ( ASHRAE-55 , 2004 ; CIBSE , 2006 ; Szokolay and Docherty , 1999 ; ISO-7730 , 1994 ).
Table 2 presents the comfort temperatures and thermal boundaries for 90 % and 80 % of occupant acceptability on each season . Tn was calculated using the formula from ACS , the average outdoor temperatures , provided by a local meteorological station were calculated over the 42 monitored days of each season . Once the boundaries were established , the measurements were compared against the comfort zone to evaluate the thermal performance . The nomenclature established in Table 3 has been used in the analysis of this study to identify the rooms and its orientation .
