The garage is to be a mechanically ventilated garage. The garage exhaust system is to consist of four fans roof-mounted or in fan rooms within the garage utilizing acoustical louvered intakes to exhaust air to the outside of the building through architectural acoustically lined plenums and discharge openings. The exhaust systems can be propeller fan type or centrifugal fan type depending on their location. The fans are to be activated by a carbon monoxide activation system. An independent rooftop closed circuit cooling tower with pump will be used to provide capacity for the auxiliary air conditioning system for future equipment loads and 24-hour cooling requirements during tenant work.
All motors serving fans and pumps to be energy efficient and rated for high efficiency.
A direct digital system of temperature controls, as well as an automated program and automation monitoring control system will be provided. Reset of operating discharge temperatures for hot water and fan system to coordinate operating temperatures with space requirements. Monitoring of all air conditioning operating temperatures to alarm for off-normal conditions. To monitor systems operation based on damper position per floor for after hours use. To control building lighting system.
