18 DEDICATED OA SYSTEM OA is dehumidified, cooled, and heated through the DOAS. Total of four Dedicated Outdoor Air Units provided. Roof mounted DOAS unit serving the BRAC 133 West Tower. OA is distributed to terminal units through a medium pressure distribution system. 18

19 DEDICATED OA SYSTEM Supplied with 42 F chilled water and heating hot water plant. Indoor DOAS unit serving the BRAC 133 East Tower. Cooled and heated to 48 F leaving air temperature. Building maintained below 55 F dew point. 19

20 DEDICATED OA SYSTEM Below 48 F ambient, the 42 F chilled water plant can be de-energized. BRAC 133 DOAS OSA intake. High latent load zones served via the 42 F system are provided with additional OA. 20

21 DEDICATED OA SYSTEM Q l =0.68 scfm/person w gr Q l =latent load/person (Btu/hr) w gr =humidity ratio difference (gr/lbm) where: Room design condition: 75F, 50% RH, W=64.9gr/lbm Q l = 200 Btu hr (per person) W for 55F SA DPT, 64.6 Gr/lbm Resulting scfm/person, 980 scfm W for 48F SA DPT, Gr/lbm Resulting scfm/person, ~20 scfm, used for design 21

22 DEDICATED OA SYSTEM DOAS Analysis Results Tower People Occupancy: 17,000 (nondiversified) Building OA Requirement: 340,000 cfm (non-diversified) DOAS Size (4 total): 85,000/unit Average OA rate: 0.22 cfm/s.f. 22

23 DEDICATED OA SYSTEM What happens if they load the building unevenly with open plan cubicles? (1,284,000 sf)/ (64 sf person) 4 DOAS 20cfm/person 100,000 cfm per DOAS unit Total DOAS capability of 400,000 cfm to allow for the flexible loading of the office tower and podium. 23

24 DEDICATED OA SYSTEM Though the use of extensive DCV, the design team expects the DOAS to operate at diversified OA flow of 230,000 cfm when fully occupied. 55 F and 42 F chilled water systems optimally sized for the expected occupant load of 6,400 people in the tower plus the podium occupant load. 24

28 BRAC 133 OVERVIEW PROJECT OVERVIEW FAN POWERED INDUCTION UNIT CENTRAL UTILITY PLANT DEDICATED OUTDOOR AIR SYSTEM ENERGY RECOVERY DESIGN CONSIDERATIONS ENERGY MODEL CONCLUSION 28

29 DESIGN CONSIDERATIONS When providing 48 F OA to the building, the cool air reduces the 55 F chilled water system load. When DCV is implemented, the zone and building wide 55 F chilled water plant load may increase due to the reduction of OA. The zone level cooling coils and 55 F chilled water plant should be sized accordingly. 29

35 CONCLUSION Utilization of a Dedicated Outdoor Air system in conjunction with a multiple chilled water plants and a Fan Powered Induction Unit system can provide an energy efficient, flexible HVAC system for a modern office tower. The FPIU system should be considered along with other DOAS terminal unit technology when selecting a building HVAC system. 35
