Jefferson Hotel – Washington DC

Engineer: Vanderweil

The Jefferson hotel is a luxury hotel located in the proximity of the White House. The scope of the project was a complete renovation / upgrade to an existing hotel. Much of the original interior construction, which has historical value, was to remain. The major requirement was to provide rooms with a quiet HVAC system that could provide humidity control in full and part load conditions. Metropolitan Equipment Group using Engineered Comfort Fan Coil Units provided a solution. Using EPIC fan technology and control sequencing of the chilled and hot water valves, fan coil operation with constant discharge air temperature was performed. The turn key factory control package provided with the DDC controller, thermostat and valve package was used to achieve design conditions. Modulating the fan and control valves to provide a constant discharge air resulted in humidity control at part load conditions, reduced fan energy cost and increased chiller efficiency.
