Saving Aileen S. Andrew Memorial Library $26,000 Annually in Energy Costs

Challenge:

The library staff realized the need for an energy-efficient humidification system to maintain optimal indoor air quality and comfort during the winter months. The existing system did not meet the efficiency and maintenance requirements of the library. Because of the harsh winter conditions and the need for high levels of humidification, the library required an energy-efficient solution. Traditional gas-fired steam generating humidifiers were too costly and inefficient, so the library staff sought a better alternative.

Solution:

A MeeFog high-pressure humidification system that controls the environment of the library’s newest addition using two air handlers with a total airflow of 60,000 CFM and a humidifier capacity of 1500 pounds per hour. The staging solenoids manage the load by activating nozzle headers in various combinations, and excess moisture is collected on droplet filters and drained away. The total electrical load for the system is only 1.25 kW.
