Engineering Systems
Mechanical
This building utilizes the design conditions found in 2009 ASHRAE Handbook Fundamentals, chapter 14, Climate Design Information, with 0.4% and 99.6% annual cumulative frequency of occurrence values. This building’s mechanical system consists of a multitude of different units, including: 2 25-ton packaged outdoor air handling units that each have an airflow of 3210 cfm; 5 Air Cooled Condensing Units (D/X split systems) that are 3, 3, 5, 20, and 30 tons; 4 Split system indoor air handling units; 5 Indoor Air Handling Units; 3 small (2,3, and 2 ton) split system outdoor condensing units. Most of this equipment is located on the roof of the building. The guest rooms are each served with their own Variable Air Volume (VAV) Boxes. Each of the restrooms, kitchens, and other spaces that require exhausting are exhausted according to code. The building is in compliance with all of the codes listed in the building statistics.
Electrical
This building’s electrical system can be summarized as utilizing a voltage of 120/208 WYE, 3 phase, 4 wire. The main power supply comes in from the utility through a stepdown transformer which then feeds to the two main switchboards, MSB1 and MSB2. Both of these switchboards are 120/208 WYE, 3 phase, 4 wire; and have a 2000A rating. MSB1 then feeds 7 panel boards, while MSB2 feeds 8 panel boards and 4 smaller branch panels. There is also a 125.5 kVA generator in a room that also includes a 200kW Standby Generator on the first floor that serves the fire pump which is controlled with integral disconnect sized to conform with NEC Article 695 and NFPA 20, and goes to 3 way switches that will switch from the main power to the generator power in the case of an emergency.
Lighting
The Hyatt’s lighting design emulates the buildings vibrant and upbeat feel as well as its focus on sustainability. Throughout the building are energy saving LED’s, Fluorescent, and halide lamps. The lobby contains a large semi-circular curtain wall that allows for an abundance of natural light in the common spaces and restaurant area.
As an increased measure of sustainability individual lighting controls for 90% of the building occupants were included in the design to enable adjustments to suit individual task needs and preferences.
