Provide dedicated system for outside air ventilation to optimize thermal comfort, moisture control and energy performance.
Projects fulfill applicable options:
Option A: Dedicated Outside Air System (DOAS) (1 point)
Decouple outside air introduction from the building’s heating and cooling systems by installing a DOAS for at least 90% of outside air flow rate requirements. Ventilation air must be pre-conditioned before it is introduced into heating and cooling system or conditioned spaces. System must have filter that is accessible for maintenance.
Option B: Pre-Conditioning Outside Ventilation Air with Energy Recovery (3 points)
Employ pre-conditioning strategies to temper incoming ventilation air using an energy recovery ventilation (ERV) system. System must be easily accessible and have a filter that is accessible for maintenance.
- Construction Documents indicate DOAS and ventilation pre-conditioning strategies
