GOC376853 - Consultant - EWA Boiler and Humidification upgrade

The intention of the project is to Replace the 2 existing boilers that are 20 years old with high efficient units. Upgrade current humidification source and supply. Consultant to investigate existing status of operation. Consultant to provide estimation of energy savings for this work. Currently two steam boilers used for heating and humidification. The supply air from AHUs is humidified by injecting steam from the boilers directly into the supply air stream. The direct-injection design can cause indoor air quality problems for buildings. The chemicals used to treat the boiler feed water can be carried by the supply air into the occupied spaces and breathing zones. It is recommended to replace two boilers with condensing units and install new humidifier. All piping outside the boiler room is already converted to hot water (heat exchanger steam/glycol in the boiler room). P&S in 1st year and implementation in 2nd year.
