HVAC Upgrade for K-12 School District

A K-12 school corporation in NWI needed to upgrade the existing HVAC systems for multiple school buildings and classrooms in the district. These updates were mandated to comply with current outside air requirements, while a side benefit would be the reduced energy consumption. Superior Engineering (S/E) was asked to provide the required detail engineering, construction drawings, engineering specifications for the equipment and materials, purchasing assistance and construction support for this important project.

Collaboration with the school district was critical in the beginning stages of this project since the exact solution to improving the air-quality and energy consumption was not known. S/E investigated the current HVAC system and developed solutions with multiple alternatives, each with its own costs and schedule impact.

The final solution included integrating the existing chiller into the Niagara based Building Automation System (BAS). Direct Digital Controls (DDC) were added to the BAS, replacing the original pneumatic systems. This involved replacement of the conventional boilers, upgrades to the air handling units, installation of new rooftop units and sizing of the variable air volume (VAV) reheat boxes. Fan Coil units (FCU) were replaced due to under sizing, and building modifications were made to the structures to support the new equipment.

Project execution followed the American Institute of Architects (AIA) format and procedures.

S/E also completed the Application for Construction Design Release (ACDR) package along with the Professional Engineer (PE) seal as required by the state and local regulating agencies.
