The City and County of San Francisco have chosen technology from Nagle Energy Solutions (NES) to provide the design for the upgrading of mechanical ventilation systems in three garages owned by the city, according to the company. The technology will be used in the Golden Gateway, Sutter-Stockton and Japan Center garages, the company said.
The release says that the NES digital, demand control ventilation system (DCV) uses smart control logic to detect and measure fumes and subsequently modulate fans. The system measures carbon monoxide and, in some cases, nitrogen dioxide. The system radically reduces energy used in garage ventilation systems, the company says.
The city, the release says, plan to specify the use of the NES TR Series ventilation control systems. It incorporates Tridium’s JACE controller and Niagara programming framework.
NES Principal Partner Frank Nagle described the system to Energy Manager Today earlier this year.
