4. Mechanical Design Narrative Building 3 has several different types of HVAC equipment that serves different areas within the building. Area 1 is currently designed as three conference rooms and has its handled by AHU 3-1, AHU 3-2, and receives fresh air from DOAS 3-1. Three VAVs are currently installed in this area, two on the supply ductwork and one on the DOAS ductwork. This space is to be reconfigured into four smaller conference rooms, which should require minimal mechanical alterations. Area 2 is a large open office area with many small perimeter offices and is served by AHU 3-2 and fresh air is provided to this area by DOAS 3-2. Eleven VAVs are installed in this area, three installed on the DOAS ductwork and eight on the supply air ductwork. This space will continue as an open office with small perimeter offices, but locations of offices will be changing, and ductwork will need to be reconfigured to accommodate the new layout. Area 3 is designed as a large open office which is served by AHU 3-2 and fresh air is provided to this area by DOAS 3-2. Two VAVs are present on the supply ductwork, and one is present on the DOAS ductwork. Area 3 will be divided into two conference rooms by a new demountable wall and will need to be rebalanced. Area 4 is a large open office area with four small perimeter offices and is served by AHU 1, which only serves this area and is not equipped with any addition VAVs. This space will remain a large open office with four small offices; however, the locations of the offices are being changed and ductwork will need to be reconfigured.
