Summary

The improvement of the buildings’ energy performance is being realized to be more than ever imperative. The international legislation framework and the standards outline the need to achieve buildings that achieve energy efficiency (2010/31/EE) and ensure a comfortable thermal environment for the occupants (ISO 7730). This applies in particular in the case of office buildings, where the well-being and productivity of the employees is essential and is inextricably linked with the prevailing indoor thermal comfort and air quality conditions. In the framework of this paper, the results of a post occupancy evaluation campaign focusing on indoor air quality conditions, in two buildings in Thessaloniki, Greece, are presented. The climate characteristics of the area are similar to the majority of the cities in Mediterranean. The two office buildings were constructed in 1995 and 1998, therefore they complied with the first national thermal insulation regulation. During the in situ evaluation a variety of indoor parameters were measured, as the indoor temperature, relative humidity and CO2 levels along with the PMV index. In addition to the monitoring of the aforementioned parameters, a qualitative evaluation of the indoor conditions was carried out. In both cases, a reveal preference survey was conducted and a variety of social characteristics and personal beliefs concerning the indoor environment was determined. Moreover, an inferential statistical analysis was carried out and probable correlations between the occupants’ complaints about indoor conditions and the indoor thermal and air quality during winter period were specified.
Concluding, the determination and evaluation of the indoor conditions of the existing building stock and their linkage to personal characteristics and beliefs is essential, as it can demonstrate the parameters that should be taken into consideration both from policy makers and building developers for creating not only nearly zero energy but also sustainable ones and such that are friendly to their occupants. Therefore, a firmed evaluation of the existing conditions and the designation of the parameters that affects the occupants’ expression of complaints should be specified and evaluated in every stage of the deciding making process.
