Tower Engineering, Inc. provided HVAC, Electrical, Technology, Plumbing and Fire Protection engineering services for the renovation of Ihmsen Hall at Mount Aloysius College. This three-story freshman residence hall was subject to a full architectural and MEP renovation as well as an elevator addition. The building includes a resident life apartment in addition to a large resident lounge with a full kitchen. Suite-style resident rooms include integral bathrooms and air conditioning.
The HVAC system design utilizes self-contained dedicated outside air (DOAS) units and 4-pipe, vertical stack fan-coil units to serve the resident suites. A new high efficiency condensing gas hot water heating plant provides heating while an air-cooled chiller plant provides cooling to the building. The packaged DOAS units allow for efficient dehumidification at times when the heating plant is not operational.
The electrical design included a new underground utility service and a diesel emergency generator, and the building is protected by a lightning protection system. The lighting design includes accent lighting on the existing exterior decorative archways. A new fire alarm system was installed along with security surveillance with card access and telecommunications cabling.
The plumbing design includes a central domestic water heater and water efficient plumbing fixtures. The building is protected with an automatic sprinkler system. The large exterior canopy and upper level attic spaces are protected by a dry fire protection system.
