Occupancy-counter-based control system. Final report
Excessive mechanical ventilation of commercial and institutional buildings can result in significant waste of energy required for space heating and cooling. Ventilation rates are typically set to satisfy building design occupancy levels, in accordance with local codes, even though the building may s...
