The general scope of work was to provide MEP engineering and lighting design services for the “Office of the Future,” approximately 23,000 SF, located on the first floor of the UMUC Administration Building. CFR provided design for latest energy monitoring systems for all MEP systems. CFR also provided lighting design services and selection of lighting fixtures.
The lighting design goal for this project was to design a modern open collaborative office space that created a fun and adaptive environment for the ever-changing office space. The architectural and lighting intent was to create a very open office environment with a mix of cloud ceilings and no ceiling areas. Orderly random lines of light were created with varying lengths of pendant or recessed linear lights depending on the ceiling conditions. One major challenge was the fact that most of the space did not see daylight due to limited window exposure. To provide occupants with a sense of daylight, the back walls of all offices without windows were wall washed with a perimeter linear light fixture. To also bring the outside in, two garden walls and a garden “Picnic-Break” room were created in the interior of the office space. These garden areas were lit with a combination of white LED grow lamps as well as tunable LED white lights that were programmed to automatically match the color temperature of daylight that naturally takes place during the day.

This project included mechanical and electrical engineering design services and construction administration services for the renovation of approximately 4,000 SF of space. Renovations included reconfiguration of the existing spaces to include new offices, a new storage room with break area, and new conference rooms. CFR also provided the lighting design and fixture selection for the project. CFR worked closely with the architect and NCI's in house interior design group to come up with a modern and clean lighting design.

CFR provided computational fluid dynamic (CFD) modeling services in order to assist in trouble shooting an AHU operational problem. There was a current issue with the freeze-stats on two 100% OA AHU’s with a steam face and bypass pre-heat coil. CFR modeled baffle plates that force the bypass air to mix with the heated air passing over the steam heating elements so as to provide a better mixed condition. Additional chilled water was being utilized unnecessarily because the steam PHC LAT set point needs to remain at 80 degree F to avoid the freeze-stat tripping off the AHU

This project included a CFD/mechanical engineering analysis of displacement ventilation for a new microscope room. A CFD/Mechanical engineering analysis is being provided to compare the following displacement ventilation scenarios in each model; high supply air with high return air, high supply air with low return air, and low supply air with high return air to determine which is best to achieve a uniform airflow and temperature gradient throughout the space.

This project included lighting improvements for a confidential government agency. The researchers of the Nuclear Magnetic Resonance (NM) Research Lab needed a lighting system that would meet the needs for high light levels while also being able to work within the highly magnetic fields inherent to the lab.The lab uses some of the largest magnets in the world to conduct their research, which means the light fixtures and all other materials within the lab must be non-ferrous and also work within the highly magnetic fields. The lighting design was constrained to utilizing 2x2 light fixtures at the pre-determined locations within the room, such that the existing specially designed non-ferrous ceiling panels could be re-used for this project. With this design constraint and the fact that the ceiling itself was 25 feet above the finished floor added to the challenges for achieving the user’s goal of an average of 60 FC on the work plane of the entire lab with a minimum uniformity ratio of 2:1.
Working closely with a manufacturer, semi-custom 2x2 high-output LED light fixtures were developed such that they worked within the highly magnetic environment but also provided a maintained average light level of 65 FC and less than a 2:1 uniformity ratio. Due to the complexity of maintaining the lights in the ceiling and lift interference with the lab equipment and magnetic fields, the LED drivers were remotely mounted in a part of the lab that would allow them to be easily maintained outside of the efforts of the magnets. The lights were connected to 0-10V dimmer switches and zoned into three separate zones for ultimate user control within the lab. The project met all the user’s expectations for quality light, control and budget.

Project includes electrical system studies for the Department of Veterans Affairs Medical Centers (VAMCs) at three (3) locations; VA Medical Center, Loch Raven VA Outpatient Clinic, and Ft. Meade CA CBOC. CFR is currently providing complete short circuit, coordination and arc flash study including voltage drop calculations on the entire electrical system/s (both normal and emergency) at each VAMC site listed above. It shall begin at the incoming utility electrical service (for the normal system) and at the emergency generators (for the emergency system) and continue through to each branch circuit panelboard, motor control center or motor control panel in each building. The total square footage of medical centers to be studied is approximately 736,134 SF.

Project included MEP engineering design services for the conversion of the existing two–story, historic veterinary clinic into a school. Renovations to the approximately 14,600 SF of total space includes 10,500 SF of space on the first floor to be converted into five (5) middle school classrooms, four (4) pre-school classrooms, a multi-purpose room, a kitchen with sink, a reception area, two (2) ADA staff restrooms, two (2) ADA student restrooms, a director’s office, a staff work room, a sick student room, and three (3) storage rooms. The second floor consists of 4,100 SF of warm-lit shell space.
In addition to the MEP engineering services, CFR also provided lighting design services for interior and exterior of the historic building as well as exterior site lighting. Since the building is considered historic, careful lighting decisions had to be considered on how to apply the light while maintaining the aesthetics of the original building. To assist in gaining approval by the local historic preservation board; light massing renderings (pictured above), photorealistic lighting renderings, and conceptual drawings were created.
