2.3.2. Number and location of sampling points
After the collection of all the mentioned data, an integrated analysis of the hotel building was done to determine the quantity and locations of the sampling points. All spaces of the building with human occupancy were grouped by zones. Accordingly, the hotel building was divided into 7 different zones based on the ventilation system supplying each zone, the type of activity in the zone, thermal loads, and source of emissions.
Brief overview of the zones and number of measuring points, as well as their corresponding HVAC system are presented in Table 1.
