BGSU Hanna-Maurer Center

Bowling Green State University’s Hanna-Maurer Center is home to their College of Business, where discovery-based learning happens in multiple hands-on experimentation spaces, including a mock Wall Street trading floor. This project includes the complete renovation of Hanna Hall, one of three original structures on BGSU’s campus and the building of the Maurer Center, just two inches from Hanna Hall. Hanna Hall's former east exterior wall now serves as a key part of the three-story atrium connecting the two structures and JDRM Engineering's Technology Department's design of an innovative presentation of stock market tickers is the highlight of this striking space.

Mechanical Systems

The building’s systems were designed to reduce energy consumption by exceeding the ASHRAE 90.1-2010 requirements while complying with the mechanical code. During the schematic and design development phases of the project, different wall and roof insulation values were evaluated in the building model. The cost of the insulation was evaluated with regard to the long-term energy performance of the structure.  In addition, the quantity, size, and performance of the glazing were extensively evaluated to provide BGSU with the most energy-efficient and aesthetically-pleasing result. These measures were also evaluated against the mechanical equipment sizing and associated costs.

The supply air to the building is provided by two custom outdoor air handling units enclosed in a single cabinet. The units consist of a supply fan wall, return fan wall, hot water heating coil, chilled water cooling coil, high-efficiency filters, sound attenuator, an energy recovery wheel, and outside air, return air and exhaust air dampers.  The supply air is distributed via variable volume reheat boxes with perimeter radiant ceiling panels.

The project’s hot water heating system includes a hot-water-to-steam heat exchanger with variable speed building distribution pumps. The steam is generated from the campus’ existing steam plant. Chilled water is generated from the existing campus’ chilled water plant and distributed with variable speed pumps.

The Direct Digital Control (DDC) system is connected to the existing campus’ system and monitors space temperatures as well as HVAC equipment operation. There are also multiple metering devices to observe electrical power usage, water consumption, gas consumption, and lighting power usage, as well as fan and pump consumption.

Electrical Systems

JDRM Engineering provided lighting, power, and fire alarm design. The lighting incorporates a full-LED design with daylight harvesting, compliance to ASHRAE 90.1 energy code with individual room control, and dimming throughout the facility. Power system design includes multiple points of energy monitoring for different departments and a complete upgrade of the distribution switchgear in the existing portion of the building plus new distribution throughout the addition portion. The fire alarm design is an innovative solution with smoke evacuation control in the Atrium area. Integrations with the exterior door operators and the security system utilize the outside doors as the relief air for the smoke evacuation system in lieu of dampers and louvers, ensuring the signature architect’s design intent. Generator emergency power provides for life safety systems, technology systems, and key building functions and services.  Power distribution spans three levels of surge protection for sensitive electronic equipment.

Plumbing Systems

The century-old Hanna Hall plumbing system was demolished and completely rebuilt with a new piping system, plumbing fixtures, and equipment. The storm and sanitary drainage systems utilize gravity drainage to the building sewer where feasible while a lift station provides for sanitary, elevator pit discharge, and subsoil building perimeter drainage systems which are located below the basement floor. The roof drainage consists of primary and secondary roof drains with separate piped discharge. The new domestic water service includes metering, backflow prevention, a pressure booster system, a water softening system, boiler make-up water, and a piping distribution system consisting of domestic cold water, hot water, and hot water return piping. Domestic hot water is supplied by a steam-to-water semi-instantaneous indirect water heater with an electronic mixing valve. The natural gas service includes metering, pressure regulating, and distribution piping to required mechanical equipment.

Fire Protection Systems

New water service is provided with a double check valve assembly and wet system riser serving both the existing building and the newly constructed space as well. Standpipes are provided in required stairwells with fire department hose connections and floor control valves to supply each floor. Concealed sprinklers are provided where there are finished ceilings

Technology Systems

JDRM Engineering provided full Technology Design and discipline lead/management for a complete Telecommunications design including structured cabling, pathways, Telcom room design, grounding, security system, access control, AV Systems, Network Electronics, and a Wireless Network. Our work also included extensive budgeting/estimating services for the $2 million AV system. JDRM provided construction oversight and specifications as well as serving as the interfacewith the Owner’s project management team, end-users, architects, and engineering disciplines.


This project has become LEED Certified – Silver.
