Cogeneration is a thermodynamically efficient use of fuel. In separate production of electricity, some energy must be discarded as waste heat, but in cogeneration this thermal energy is put to good use in a process that is generally much more energy-efficient than the separate generation of electricity and useful heat.
EBL’s design work included modifications to the existing boiler plant required for hot water generation, cogeneration heat recovery system integration, sequences of operation, pumping systems, natural gas system piping modifications, hydronic heating supply and return and domestic hot and recirculating piping between the plant and various existing delivery points, modification of delivery points to accept hot water, centralized domestic hot water generation system, domestic hot and hot water recirculation system design control system modifications and requisite electrical design to support hot water generation and delivery equipment.
Electrical design services included resizing switchgear, transformers, interconnecting circuit conductors, coordination of disconnects with utility requirements and calculations required for the 500 kW cogeneration equipment.

This past semester, EBL Principal and MDDF Lieutenant Colonel Ed Hubner was invited to teach a course on Infrastructure and Society in the College Park Scholars Program. The class focused on the need to continually inspect and evaluate infrastructure to determine is condition, suitability and to prioritize capital reinvestment. The class included basic instruction on buildings mechanical, electrical and structural systems as well as condition assessment. The class was modeled on the Army’s Installation Status Report (ISR) system. The final project included a full assessment of the BG John R. Kenly Armory in Greenbelt Maryland.

EBL Engineers, LLC (EBL) is proud to announce that the Chalon Residence was presented with an AIA Maryland Design Excellence Award. The project was designed by Dynerman Architects PC with EBL Engineers serving as The Engineer of Record and Horizon Builders serving as the General Contractor.
A highlight of the Chalon Residence design is the HVAC systems which consist of closed loop, vertical bore ground source heat pumps connected to ducted forced air distribution systems. A closed loop, vertical bore heat exchanger field array with approximately 44 tons of capacity serves as the heat sink/source for all HVAC heat pumps. Energy recovery to the domestic water heating system via heat pump unit on board de-superheaters has been incorporated to improve energy efficiency. High efficiency, modulating, condensing gas boilers and a low temperature heating water system provide the thermal source for domestic hot water generation, pool heating, floor warming and driveway snow melt systems. All pumping systems were equipped with variable frequency drives or electrically commutated motors (ECM), allowing the hydronic systems to reduce energy consumption as building loads decrease. A centralized, digital plant controller provides sequencing and optimization of the hydronic systems insuring maximum energy efficiency is being obtained. Some notable design components include the 24,000 sq. ft. main house, a small guest house, pool & pergola, a dining room that will seat 40, an in-house squash/basketball court, and a home office perched on the third floor high among the branches.
Dynerman Architects is a small, versatile, design-oriented firm. Led by Alan Dynerman, FAIA, the firm has earned a reputation for listening to and embracing their clients’ goals, professional service and design excellence. Their office works from a point of view that is based on a few simple ideas: that the nobility of architecture is rooted in its reality and utility; that the two mediums of architecture are materiality and construction; that the integration of architecture and site is the first measure of good work.

EBL Engineers, LLC was recently awarded the “Engineering Excellence Honor Award” from the American Council of Engineering Companies of Metropolitan Washington ACEC/MW, “Outstanding Project Award” from ACEC/MD and “National Recognition Award” from ACEC National for its role in the Net Zero Energy Residential Test Facility (NZERTF).
The honor award is presented to recognize those engineering achievements demonstrating the highest degree of skill and ingenuity while providing a significant benefit to the public welfare and practice of consulting engineering.
As engineer of record, EBL has been proud to play a key role in the NZERTF initiative. The structure was designed to demonstrate that a residential structure, similar in size and aesthetics to the surrounding homes in the Gaithersburg area, will generate as much energy on an annual basis as it consumes. The test facility had been designed to simulate conditions that mimic a residence occupied by a family of four.
