The Project: Oglebay WVU LEED Certified
West Virginia University transformed its historic 54,000 sq. ft. Oglebay Hall into a state-of-the-art forensics laboratory and classroom building. Dating from 1916, the new 74,000 sq. ft. building includes DNA and molecular biology laboratories, electron microscopy, bone analysis, gas chromatograph, ballistics analysis, blood, fingerprint, and trace evidence analysis facilities, as well as classrooms, faculty and graduate student offices, and new Auditoriums. The project has been designed for and achieved LEED® certification.

CJL Engineering Design Solutions:
• High performance window glazing system for beneficial daylight will reduce thermal losses
   and solar heat gain. Lighting systems adjust to daylight levels and automatically dim
   and shut off, saving energy.
• HVAC systems provide exceptional indoor air quality and energy efficient performance.
   Variable speed drives reduce energy use during part load conditions, and the HVAC
   systems use environmentally friendly refrigerants.
• HVAC systems provide exceptional indoor air quality and energy efficient performance.
   Variable speed drives reduce energy use during part load conditions, and the HVAC
   systems use environmentally friendly refrigerants.

The Project: Katz Café
The new Katz Café is the result of the basement retrofit of Mervis Hall, at the University of Pittsburgh. CJL Engineering designed the Mechanical and Electrical Systems for this Starbucks-like coffee bar and Internet café. Mervis Hall houses the Katz Graduate School of Business.

CJL Engineering Design Solutions:
• Abundant use of down lighting and low-voltage track lighting with dimming
   features – augmented by fluorescent lighting.
• Power provided to equipment and to data network areas.
• Café accommodates a wireless Internet receiver, as well as data outlets.
• Existing HVAC was modified and retrofit to café application, and load requirements.

The Project: Point Park University Dance Studio
Lawrence Hall is a 21-story tower in Downtown Pittsburgh, the anchor structure of the Point Park University urban campus. Project included a new 54,000 sq. ft. dance studio complex, central cooling plant, steam boiler plant, and significant Mechanical and Electrical modernization for the historic 300,000 sq. ft. structure. CJL Engineering provided HVAC, electrical, lighting, Information Technologies, plumbing, and fire protection, as well as green/LEED® engineering services.

CJL Engineering Design Solutions:
• The studies were designed to meet the rigorous air quality, lighting, and thermal comfort
   requirements of student and faculty dancers. Increased levels of highly filtered and
   tempered fresh air, thermal and humidity control, daylight and non-glare lighting, non-VOC
   interior finish materials provides state-of-the-art conditioning
• New high efficiency Central Cooling Plant provides energy efficiency, including low
   temperature chilled water, expanded chilled water/condenser water temperature
   differentials, variable primary pumping, waterside economizer. The plant is expandable for
   future phases
• New central steam plant provides high efficiency boilers with summer/winter capacities
• State-of-the-art HVAC Systems provide exceptional temperature/humidity control, high
   levels of outside air, and high performance filtration. Radiant heating provides enhanced
   student/faculty controlled comfort to minimize drafts and provide improved warm-up
   conditions to avoid injuries
• Demand Controlled Ventilation uses CO2 sensor controls to match ventilation air levels
   with occupancy/activity levels, enabling the HVAC system to provide Indoor Air Quality in an
   energy efficient manner
• High performance glazing systems admit visible daylight, while providing exceptional
   thermal and solar performance to reduce heating and cooling loads, and avoid radiant
   losses for dancer comfort
• The high efficiency lighting systems include daylight sensors and controls, which reduce
   lighting energy in studios and circulation areas when daylight levels are sufficient.
   Occupancy sensors shut off lights between classes
• The new Electrical Plant accommodates the new Central Cooling Plant, the new Heating
   Plant and Domestic Water System to serve future expansion plans for Lawrence Hall
   and the Dance Studio
