The Mission

Create a mixed-use development with 370,000 square feet of office space, 20,264 square feet of retail space and a 130-car underground parking garage. Responsibilities included constructing a 20-story tower and renovating a five-story building that is named on the National Historic Register.

The Solution

We created this office tower to be a blend of 18th, 19th and 20th century architecture with rose-color granite on the north and south sides and an emerald-green curtain wall on the west and east facades. The structure has a Variable Air Volume HVAC System that is activated and controlled by a main computer and nine mini-computers. The system utilizes people and equipment heat to warm in winter and fall and exhausts that heat in spring and summer. On days when the temperature is perfect, the air from outside is used and distributed throughout the building.

The Details

100 Westminster Street features a 200’ long, 47’ high galleria, which has a vaulted glass roof with over 3,432 tube lights.
