About this file
This document is a comprehensive HVAC design and control specification package for the Paul H. Douglas Environmental and Learning Center at Indiana Dunes National Lakeshore. The file includes detailed equipment schedules, piping and floor plans, electrical schematics, control wiring diagrams, and operational sequences for a facility's heating, cooling, and ventilation systems. The facility utilizes six air handling units (AHU-1 through AHU-6) manufactured by AAON Coil Products with Schneider Electric and Toshiba controls, supplemented by two Lochinvar boilers (KBN400 series), an AAON air-cooled chiller, and multiple Bell & Gossett pumps for heating and chilled water distribution. Equipment is distributed across lower-level mechanical rooms and dispersed locations throughout the facility, with control integration managed through Schneider Electric automation servers and NEMA enclosures.
The control sequences specify single-zone variable air volume operation with occupied/unoccupied scheduling through the building automation system, cooling maintained at 55°F discharge air temperature and heating at 95°F. Heating water system operation includes lead-lag boiler control with load sharing, activated when outdoor air temperature drops below 65°F, with supply temperature reset linearly from 110°F at 60°F outdoor air to 160°F at 30°F outdoor air. The chilled water system operates independently when outdoor air temperature exceeds 55°F with 45°F supply temperature setpoint, utilizing lead-lag pump rotation every seven days for balanced runtime. Safety protocols mandate manual reset of all tripped devices, low-temperature limit switches shut down supply fans, and fire alarm contacts trigger emergency shutdown. The specification also includes detailed valve schedules, window switch wiring for six zones, boiler cascade wiring controls, and comprehensive DDC alarm generation requirements for equipment status mismatches.
