WHAT ACCO DELIVERED
ACCO’s design for the Airbnb, 888 Brannan project is unique considering that the building was built in a few phases of construction that started from 1917 up to 1986. The floor to floor heights in some parts of the building is very tight. Construction was challenging and ACCO played a major role in the coordination process.
The project consists of new mechanical systems for the two buildings. The house systems are VAV cooling only packaged units with hot water reheat for Building 870 using a high efficiency
condensing boiler and constant volume rooftop heat pumps for Building 850. A fluid cooler delivering approximately 300 tons is used for after hour systems and retail space cooling. Water source heat pumps were used for basement retail space due to space constraints.
Sunbelt Controls provided the Automatic Logic DDC control systems and their role was very rewarding.
