Energy Exchange
The energy exchange inside the human body is a combination between the Metabolic Rate and the energy exchange due to Mechanical Work. The PMV Model uses constant average values for different activities. Depending on personal conditions (age, weight, ..) this values may vary over a wide range. The following lists provides example values for typical activities in urban areas.
| Activity | Energy Exchg. W/m² | Mech. Factor |
|---|---|---|
| Sleeping | 41 | 0 |
| Sitting | 58 | 0 |
| Standing | 70 | 0 |
| Standing, light activity (e.g. shopping) | 93 | 0 |
| Walking (Speed, Inclination): | ||
| 3 km/h, 0% | 116 | 0 |
| 5 km/h, 0% | 150 | 0 |
| 6 km/h, 0 % | 220 | 0 |
| 15 km/h, 0% | 550 | 0.3 |
| 3 km/h,+5% | 175 | 0.10 |
| 3 km/h,+15% | 270 | 0.19 |
| 2 km/h,+25% | 210 | 0.20 |
