Architecture
| Design and Functional Components | The HBCCH is comprised of two separate buildings (East and West) connected by a two-story walking bridge that spans over Eutaw St. The East Building is a three story structure which houses a restaurant, Starbucks, junior ballroom, and numerous meeting/conference rooms. The second floor of the East Building also has a second walking bridge that spans Howard St. to allow patrons to access the Baltimore Convention Center. The first three levels of the West Building hold the hotel lobby and lounge, large pre-function areas, grand ballroom, swimming pool and workout areas, and more meeting/conference rooms. The western side of these floors and also the two below-grade levels underneath house the 250,000 sq. ft. parking garage. The West Building also has two towers that rise up on its northern and eastern sides. The 758 hotel guest rooms are located on floors 4-19 of these towers. Floors 20 and 21 are for service use only. |
| Major National Model Codes | IBC 2000 (as amended by Baltimore City) |
| Zoning | Commercial / B-5-1, not located within the Chesapeake Bay Critical Area |
| Building Envelope | The envelope of the guest room towers of the West Building is made up of non-load bearing metal wall panels and fixed aluminum windows with vision glazing. The lower levels of both buildings have an envelope that combines a glazed aluminum curtain wall system with vision and spandrel glazing along with a non-load bearing brick façade. Both buildings utilize two different roof systems. An adhered PVC membrane roof over insulation and steel deck is the roof system for the guest room towers and portions of the lower roof levels. The majority of the lower roof levels of both buildings is a green roof system comprised of steel deck covered by insulation, drainage panels, and a lattice with growing medium for the plants and grasses above. |
Part II
Mechanical System
The HBCCH utilizes both district chilled water and steam. District chilled water, purchased from ComfortLink, is supplied to two 1,000 ton heat exchangers. Chilled water piping is distributed in two main pumping zones; one zone is the guest room towers, and the second zone is for the east and west podium public areas. Two variable speed pumps are provided for each zone, each sized for 60% of the design flow rate. The chilled water system is designed for a fourteen degree temperature difference between the supply and return. All 8 AHUs and 4 MAUs are served by the district chilled water system.
Trigen generated district steam is sent to two heat exchangers where it is converted into heating hot water. Each heat exchanger is sized for 810 gpm and 6,500 MBH. Three dedicated variable speed pumps distribute the heating hot water throughout the building.
Electrical System
The Baltimore Gas and Electric service enters the West Podium and splits three ways. A 2000A 480/277 service supplies the East Podium while two 4000A 480/277 services supply the West Podium. The building is equipped with a 1100 kW emergency generator. Most of the public of the HBCCH are lit by a combination of recessed and surface mounted compact fluorescent lamps. The hotel guest rooms are lit by incandescent lamps.
Structural System
The exterior walls of the HBCCH are all non-load bearing. Steel encased concrete columns bear on drilled caissons or caisson caps. The remainder of the foundation has spread footings bearing on reinforced soil. The hotel guest towers and podium spaces utilize a two way flat concrete slab flooring system, and both of the pedestrian bridges spanning the roadways are supported by steel beams.
