Type of data | Description |
---|---|
E. Indoor Physical Parameters | |
E1. Indoor Air Temperature (Ta) | Air temperature measured in the occupied zone at 0.1, 0.6, and 1.1 m above the floor (°C) |
E2. Indoor Relative Humidity (RH) | Relative humidity measured in the occupied zone at 0.1, 0.6, and 1.1 m above the floor (%) |
E3. Indoor Air Velocity (V) | Air velocity measured in the occupied zone at 0.1, 0.6, and 1.1 m above the floor (m/s) |

E5. Room Surface Temperature | Measured internal surface temperature of floor, wall, and roof surface (°C) |
F. Indoor Calculated Parameters | |
F1. Operative Temperature (Top) | Calculated operative temperature in the occupied zone (°C), it was calculated according to ASHRAE 55-202013: Top = A × Ta + (1-A) × Tr, when v < 0.2 m/s, A = 0.5; 0.2 < v < 0.6 m/s, A = 0.6; 0.6 < v < 1.0 m/s, A = 0.7 |
F2. Mean Radiant Temperature (Tr) | Calculated mean radiant temperature in the occupied zone (°C), it was calculated according to ISO 7726-199830: Tr = [(Tg + 273)4 + 2.5 × 108 × v0.6 (Tg-Ta)]1/4-273 |
F3. Radiant Temperature Asymmetry | Calculated radiant temperature asymmetry in the occupied zone (°C) |
F4. PMV | Predicted mean vote, it was calculated according to ASHRAE 55-202013 |
F5. PPD | Predicted percentage of dissatisfied, it was calculated according to ASHRAE 55-202013 |
