This mixed-use development in the heart of Arlington’s Ballston neighborhood includes a 350,000 SF office tower. Its mechanical system consists of floor-by-floor air conditioning (AC) system with fan-powered variable air volume (VAV) boxes and a water economizer. Amenities for high-tech tenants include underground electrical service that provides 5.5 w/SF of power for equipment and lighting and provisions on the roof for emergency generators and an uninterruptable power system.

The destination also features a 336-key Westin Hotel offering a full ballroom, meeting facilities, restaurant, lounge, Starbucks Cafe, and retail outlets. The hotel’s mechanical system has central chill water and central hot water heat serving rooftop units for water supply, gas heat, air handling units for all public areas and four-pipe fan coil units for guest rooms. Its electrical system is separately metered with custom lighting and controls for all public spaces and guest room power distribution per hotel standards. The central domestic hot water system has two temperature zones to meet kitchen and public use needs.

The third element of Arlington Gateway is a 22-story apartment tower offering 415 units and a three-level underground parking garage. Here, the mechanical system consists of a through-the-wall aqua thermostat system with gas heat, hot water, and electric air conditioning. The plumbing design incorporates a special system on the roof top swimming pool for easy access by the maintenance crew.
