compare its results with the similar aspects considered in the systems used and the perception of the SBS.
3. Results and conclusions
From the work of (Lara, 2004), it is clear that institutes 1 and 3, presented higher values than those suggested by the IAQA, both in bacteria and fungi. The highest concentration of bio aerosols was presented by Institute 1, which is located in a mountainous area. Regarding the relative humidity, the three institutes presented values higher than the range recommended by the ASHRAE, of 30- 60%, and the dry temperature in all the institutes, remained in the comfort range (20-26 ° C) recommended by this same organism.
Among the results obtained from the work of (Hernández and Landaeta, 2007), the persistence of symptoms associated with the ESS was 55.4%, so the building is considered affected by the ESS, exceeding the stipulated by the WHO (20%). Regarding the magnitude of the symptoms, the discomforts that occur with a higher percentage are: headache (47.6%), sneezing in a row (42.3%), difficulty in concentration (34.8%), cough (30.7%) and nasal congestion (30.7%), which could be associated with relative humidity and temperature, whose values exceed those recommended by the ASHRAE; Directly coinciding the headache with poor lighting and few units of light bulbs, like nasal congestion and cough with ventilation problems. The areas with the highest average density of bacteria and fungi were the air handling units (UMA) of the ground floor and the first floor.
From the work of (Montozzi and Jiménez, 2018) for the BREEAM system, the building obtained the classification of 'Approved' according to the Manuals of Asset Performance and Building Management, and the classification of 'Acceptable' in the Management Manual of the Occupant, through the LEED system the building did not obtain any certification; by the HQE system, it obtained the classification of 'Good', and by the DGNB system, the building obtained the classification 'Bronze'. On the other hand, 70% of the users present some symptom associated with the SBS
