Heer & Harbourt Renovation
Kent, Ohio


This project involved the renovation of a late 1960’s residence hall to provide office spaces for multiple administrative functions including the Office of the University Architects. The original building was approximately 23,500 square feet with an 8’10” floor to floor height in most areas of the building. In addition to the renovation, a new 2,700 sq ft entry was also incorporated into the project to address accessibility issues with the existing building. Sustainability was a key focus for this project in order to achieve LEED Gold certification. The original building envelope was analyzed and improved incorporating additional insulation and window replacements. Green innovations included low-flow plumbing fixtures, high efficiency lighting, VRF zone heating and air conditioning systems, and a dedicated 100% outdoor air handling unit containing a heat recovery wheel. The energy efficiency of the VRF system and its ability to capture and reuse waste heat contributed to a high energy savings. The high degree of temperature and lighting controls installed also earned points for maximizing user comfort.

The mechanical and plumbing infrastructure was replaced in its entirety. A variable refrigerant flow (VRV) system was designed for the building with multiple indoor units connected to two separate outdoor heat pump units. The system provides simultaneous heating and cooling to the connected indoor terminal units. This allows heat to be transferred through the refrigerant to minimize the power usage of the outdoor unit. The heating units absorb heat from the refrigerant and the cooling units reject heat to the refrigerant. This enables the system to achieve very high efficiencies since simultaneous heating and cooling is required in the winter months as well as most of the spring and fall months. Ventilation air is provided through a 100% outdoor air heat recovery unit with tempered outside air ducted to the individual spaces. Energy efficiency was designed into the project through the use of the variable refrigerant flow equipment and a heat recovery air handling unit to provide ventilation for the building using a heat recovery wheel. State-of-the-art digital controls were designed to facilitate energy conservation and to assist in systems monitoring and proactive maintenance.

Electrical design included extending a 480V service entrance from an exterior unit substation to the building. A complete new distribution system was designed throughout the building. New lighting was designed incorporating T-5 lamps and energy efficient ballasts. Downlighting incorporated LED lamping technology. Occupancy sensors were incorporated for lighting controls with complete building control via Lutron control system. This was further integrated into the Johnson Control System to systematically shutdown unoccupied spaces. A complete Cat. 6 telecommunications system was also designed with rack, faceplates and patchpanels for turnkey project for an electronics vendor.

Close coordination was necessary with the mechanical, plumbing, electrical, and architectural design to maximize ceiling heights while working within areas of the buildings with 8’2” clear height from floor to bottom of precast structure above.

Each floor contains a common area, a study area, furnished alcoves at the ends of each wing, laundry rooms and refuse/recycling centers, and a large common kitchen.

The project is located on a difficult site due to an existing stream and the location of the property within the flood plain of the Ohio River. The MEP systems incorporate sustainable design concepts. The new residences will be heated and cooled with water source heat pumps to accommodate the floor plan of double bed rooms with shared bathrooms while conserving energy. The electrical design included connection to electrical utility power via a pad mounted transformer and critical power is being provided with an onsite generator. The building incorporates the use of energy efficient lighting and includes widespread use of occupancy controls and lighting control system. Fire alarm systems, area of rescue systems, and telecommunication systems were designed for the building.

This residence hall is located within 100-year flood plain limits of the Ohio River and the building itself sits over an existing 12’ diameter culvert. The design required precautions for disturbance to the existing stream and culvert system and utilized bioretention, underground stormwater management, and infiltration with grass pavers to protect the existing drainage paths. Selected landscaping was chosen to be able to handle water conditions and to encourage evaporation.

Bio-Technology Building
Huntington, WV


The Marshall University Bio-Technology Building is located on the north side of the Marshall University campus in Huntington, West Virginia. The building consists of four floor levels with a bridge over 3rd Avenue to the existing Science Building. The project included a 300 seat auditorium, vivarium space including associated cagewash / sterilization support spaces. A significant portion of the building (approximately 50,000 sq. ft) was associated with different types of laboratories including general research, teaching laboratories as well as specialized research laboratories. The specialized research laboratories included laser equipment as well as electron microscopes. The facility included provisions to allow for the addition of BSL level 3 spaces. The building also included faculty and graduate assistant research office space. Mechanical and electrical systems were designed to the Labs21 low energy lab standards.

The mechanical and electrical systems required a level of redundancy not required on most projects. The vivarium space required backup systems to the backup systems in an attempt to assure that the experiments would not be affected by utility outages. An imagine suite is located on first floor. This space houses extremely vibration sensitive equipment. Any equipment which could potentially generate vibration and noise was located in penthouse 3 floors above this space. 99.99% high efficiency terminal HEPA filter was designed for all lab area in this suite. This electrical redundancy included two independent utility feeds from separate utility substations as well as on site emergency power generation. The electrical and building automation system for the building was interfaced so that the automation could determine which HVAC, chillers, etc. were allowed to run based upon the utilities which were present. This resulted in a complex sixteen scenario utility scheme which was integrated into the building automation system. Each piece of equipment was reviewed as to how it was to function in the event of any one of the utilities and generator outage. SBM was responsible for a HVAC, Plumbing, Electrical, Telecommunications and Fire Protection design and commissioning. During the commissioning process the systems were started up and tested.

SBM was responsible for a HVAC, Plumbing, Electrical, Telecommunications and Fire Protection design and commissioning. During the commissioning process the systems were started up and tested. Not surprisingly, considering the complexity of the building, a number of problems were discovered. Examples of the problems discovered and how they were corrected are listed as follows:

The high purity lab water piping system had a tendency to sometimes spring a leak whenever the system pumps started. The leak always occurred at the faucet compression fitting connection. This problem was diagnosed as a “water hammer” problem. The problem was corrected by installing soft start starters on the system pumps.

The cooling towers for the chilled water system were shipped with the wrong motor pulleys and undersized hot water basin nozzles. The undersized nozzles was easy to diagnose because the cooling towers overflowed when balanced to the specified condenser water flow rate. The wrong motor pulleys were discovered when testing showed the motors were pulling significantly less than name plate amps. Both issues were resolved by parts and technicians provided by the cooling tower manufacturer.

Of the many pieces of Laboratory equipment on the project, the casework contractor provided two biological safety cabinets that were not the correct style. All biological safety cabinets on the project were to be of the Class 2 Type A configuration. As such the ductwork systems for the biological safety cabinets were designed with a thimble style connection. In the two cases noted, Class 2 Type B2 configuration units were provided. These safety cabinets were not compatible with the ductwork system and were changed to the specified style.

The project consists of a 15,000 sq. ft. lab annex building located at the existing Marshall University Forensic Science Center site. The building was designed as a standalone building with separate mechanical and electrical services.

The HVAC system for the building consists of three packaged rooftop units, one serving each floor of the building. The units were installed on a concrete pad on the roof for sound attenuation. Variable air volume (VAV) terminals are located in the rooms for temperature control zoning and airflow control. The lab fume hoods are provided with Phoenix control boxes to allow for two position control of the fume hoods for energy savings. Each fume hood is connected to a dedicated exhaust fan located on the roof. A sound attenuator was located in each exhaust duct to reduce noise in the rooms. Special attention was given to the location of the exhaust outlets to ensure that no fume hood exhaust would recirculate back to the outside air intakes.

A new water and fire service was designed for the project. The water meter and backflow preventers are located inside the building. The building is fully sprinkled. The water service is separated into a domestic water and lab water system with each system having its own backflow preventer and water heater. A water softener is provided for the lab water. Waste systems are also separate with a sanitary piping system for restrooms and an acid waste system for the labs. An acid neutralization basin is located outside the building for treatment of the acid waste. Primary and secondary storm drainage systems were designed for roof drainage.

The electrical system consists of a new 1200 amp three phase service and a 150 kw generator for emergency service. Interior and exterior lighting is controlled through a digital lighting control system with programmable low voltage switches in each room and a dimming system in the main lecture halls. Each laboratory has a means of disconnecting the power by activating a push button at the laboratory entrance in case of an emergency. Equipment racks with patch panels for the present and future telcom requirements are provided with cabling and outlet throughout the building. Laboratory benches are provided with a three compartment wire way for normal and emergency electrical wiring and telcom cables. Outlets can be relocated in the wire way as required by the occupants.
