Milestone329 April, 2005 ACADS Impact on the Room Acclimatization 1. Operate only at total space (occupancy independent) 2. Big reaction time 3. Thermal steady state across time 4. Thermal unnatural and neutral world 5. Low performance and efficiency (part occupancy) 1. Operate on localized spaces (occupancy dependent); 2. Low reaction time; 3. Excellent performance and efficiency (part occupancy); 4. Richer space thermal experience; 5. Symbolic and cultural role; 6. Better sustainability;
