Baggage Handling System (BHS)
The BHS typically represents a major portion of the overall energy consumptive load at airports. The BHS installed at the new Terminal B will use permanent magnetic motors which provide for the controlled movement of bags only when they are present on the system. With the capability to essentially go into “sleep mode” when not in use, the BHS is expected to save at least 37% of energy when compared to the standard old technology motors that are in use at other airports.
Solar Hot Water System
Rooftop solar hot water systems will be installed to augment the domestic hot water supply for the bathrooms. The solar hot water system, combined with the water efficient fixtures specified by the design team, will generate 78% in hot water energy savings when the new terminal is complete.
The interior lighting design is an energy saving feature of the new Terminal B. The new Terminal B utilizes LEDs in almost all applications and will provide significant energy savings. These LED lights are currently installed in the new eastern concourse and the new Central Heating and Refrigeration plant and will be installed in the headhouse (main portion of the terminal) and the new western concourse. Furthermore, the orientation of the building along the east-west allows the building to harness natural light which can be controlled using daylighting dimmers. Occupancy sensors are also deployed to optimize energy use.
The new Terminal B will feature demand control ventilation design that utilizes outside air dampers & variable air volume (VAV) systems to supply the right amount of fresh air to guests when and where needed.
Heat Island Reduction
There are two types of roof materials being used at the new Terminal B. The roof is covered with light color aluminum and PVC membrane. The light color materials reflects solar heat better than the conventional dark color ones. The apron concrete pavement also reflects more solar heat than the conventional asphalt pavement. Collectively, the design reduces summer cooling loads and greenhouse gas emissions.
Metering and Building Management System
Electric, gas, and water meters will be installed throughout the new Terminal B. The data will be recorded by the Building Management System (BMS). The building operators can monitor the building performance by reading the data of various systems, for example heating, cooling and ventilation system, lighting system, solar hot water system, and baggage handling system. It allows building operators to get the insight how the building performs and make needed adjustment or repair.
