Design of an 1800 ton hour thermal ice storage facility/waste heat boiler system adjacent to existing boiler house including three chillers, heat exchangers and three cooling towers.  The design reduced energy costs by consuming power during off-peak electrical rate periods, lessening the electrical load on the existing chilled water plant, and recovering waste heat from onsite standby diesel generators.  Supervision of the installation and integration into existing system were provided for what was at the time, the largest thermal ice storage system of any hospital on the east coast.

Solid Waste
- Design of 90-day strorage facility for solid hazardous waste materials.

Air Emissions
- Formulated application for air permits required by State of Maryland for emission of toxic gases and particulate

Waste Water
- Eliminated NPDES (National Pollutant Discharge Elimination System) permit by reducing contaminant levels by modifying existing processes used to treat water based discharges.
- Developed comprehensive RPCC (Release Prevention, Control and Countermeasure) plan
- Modified POTW (Publicly Owned Treatment Works) permit to discharge neutralized waste from extrusion press die cleaning processes.

Other
- Remedied plant wide asbestos and PCB contamination problems.
- Provided all safety and environmental training required for the facility.

The Hampton Mansion Historical Site, a 16,000 square foot historic mansion, required an HVAC system that met heating and cooling requirements while maintaining a near constant level of humidity and conformed to green building standards.  Humidity levels in the mansion had to be maintained in the range of 50-55% in order to preserve the integrity of the building, furnishings, and artwork inside.  To met the challenge of maintaining the desired temperature and humidity level while remaining within the power and efficiency requirements of green building design a ground-source water system was proposed.  KBD designed, commissioned, and supervised construction of the system.  It consisted of 7 air handlers with 2 speed water source heat pump condensing units for heating and cooling and humidification/dehumidification equipment to maintain near constant humidity levels.  The design was LEED (Leadership in Energy and Environmental Design) certified, received a Presidential Energy Award and was completed on budget and within time schedule.
