Building Enclosure
Building Façades:

Nemours Children's Hospital as a part of the Nemours Foundation is designed to withstand the effects of a category 3 hurricane. This resulted in a very extensive design for the building envelope. The modular curtain wall, constructed by Trainor, is designed with 30,000 feet of dual sealant joints to allow weeping between the two joints. A probe test is conducted after the sealant has cured to ensure the sealant is working properly. The north side of the building features a curved curtain wall that is supported by slanted structural columns. Figure 1 shows a typical section of the slanted wall system. The sunshading devices are prevalent throughout the building, and are discussed later in the sustainability section. Please see the Architecture section for the discussion of the building materials. The building envelope will be completely constructed this November.

Slanted Wall
The building has several different roofing systems to accommodate different functions of the roof. A fluid-applied membrane acts as the roofing system for the roof garden that is
accessible to patients and also doubles as a green roof. The fluid-applied membrane uses type IV extruded polystyrene board insulation.Thermoplastic membrane roofing and SBS-modified bituminous membrane roofing compromise the other roofs on the building. Each of these roofs utilize polyisocyanurate board insulation, which is type II glass fiber mat facer.
A mock-up of the Nemours Children's Hospital as a part of The Nemours Foundation has been tested in a hurricane testing lab in Florida. A 2-story, 10-bay mock-up had to pass various tests to ensure the building envelope would be able to sustain the effects of a category 3 hurricane. Laminated glass and extensive use of roof fasteners were only a few of the reasons why the building envelope passed the hurricane testing.
Sustainability Features
The design of Nemours Children's Hospital as a part of The Nemours Foundation has followed the USGBC's LEED prerequisites and credits needed for certification based on LEED for New Construction 2.2. The following items are the sustainability features highlighted in the building:
  Green Roof:
Roof Garden
Nemours Children's Hospital as a part of The Nemours Foundation has a green roof as noted in Figure 2. As mentioned in the Building Enclosure section, the green roof will be accessible to the patients.
Sunshades and Canopies:

The building has numerous sunshades to block some of the sun from the vast glass façades. Deep canopies have been designed to provide shade for large spaces on the south façade for the building. These devices will help block some of the intense Florida sun to lessen the load on the HVAC systems of the building.

Structural System
Nemours Children's Hospital as a part of The Nemours Foundation bears on spread footings on either improved or natural soils. PSI, the geotechnical firm, recommended using shallow foundations if the foundation design implemented soil improvement to increase the allowable bearing capacity used in the design. The spread footings are 1.5-3.5 ft. deep. Additionally, the elevator/stair cores sit on mat foundations that are either 2 ft. or 3 ft. deep.
The hospital and clinic portion of the 7-story building are predominately reinforced concrete structures, with the exception of steel framed mechanical penthouses. The loading dock data center and central energy plant are primarily steel framed structures. Reinforced concrete columns support Nemours Children's Hospital as a part of The Nemours Foundation, with the exception of steel columns supporting the mechanical penthouses. Two-way flat slab with drop panels, varying in depth from 9-14", is the floor system used in the clinic and hospital. Drop panels allow for higher floor to ceiling height, which allows for more flexibility with the coordination of the plenum. The loading dock data center and central energy plant are designed with one way slabs on 3"-20 GA. composite metal deck.
Lateral System:
Shear walls resist the lateral loads in the hospital and clinic of The Nemours Children's Hospital as a part of The Nemours Foundation. These walls are 12-14" thick and tie into mat foundations with dowels matching the typical wall reinforcement, mostly #8 bars. The shear walls are located in the elevator/stair core in the hospital and in the elevator bays and lecture hall in the clinic. Steel concentrically braced frames resist lateral loads in the loading dock data center and central energy plant.
Mechanical System
The 600,000 SF building uses multiple spaces to house mechanical equipment. The central energy plant houses the large mechanical equipment such as chillers, cooling towers, and boilers. The hospital and clinic have a first floor mechanical mezzanine holding some of the air handling units for the building. The rest of the air handling units are located at the mechanical penthouse on top of the hospital and clinic. Three 1300 ton dual cell chillers power the mechanical system from the central energy plant. Nemours Children's Hospital as a part of The Nemours Foundation uses 32 air handling units to provide air to all occupied spaces. A mixture of VAV and CV boxes control the air before it enters into those occupied spaces. Additionally, the hospital has lab hoods, which require a separate exhaust system.
Lighting/Electrical System

Nemours Children's Hospital as a part of The Nemours Foundation is powered by a main and 15 kV chiller source transfer switching. The system is 3-phase, 3-wire, and runs at 60 Hz. The electrical system is controlled by the power management and control system, PMCS. The system provides up-to-date information on the status of important processes and devices to the system operators. The central energy plant also houses four back up 2250 kW generators with two 40,000 gallon fuel tanks.

The lighting in Nemours Children's Hospital as a part of The Nemours Foundation is primarily fluorescent type light fixtures. A study was conducted to determine how much light pollution would the hospital cause on the surrounding area after construction. Light pollution was minimized to a LEED certified level.

Skanska USA is the construction manager and general contractor for Nemours Children's Hospital as a part of The Nemours Foundation. Construction began July 2009 and will be completed July 2012 at approximately $400 million. The project will be completed using the design-bid-build delivery method.
Nemours Children's Hospital as a part of The Nemours Foundation has six passenger elevators that service each level of the hospital and two passenger elevators that service the clinic. The elevator bays are located in the center of the hospital and south west corner of the clinic. There are also two service elevators located in the elevator bay in the center of the hospital. Three egress stairwells are located around the perimeter of the hospital. Additionally, two egress stairwells are located on opposite sides of the clinic.
Fire Protection
The hospital is in compliance with the Orlando's Building Code and applicable NFPA standards. Automatic Wet-Type I Standpipes are used throughout the building along with a wet pipe sprinkler system. Additionally, a dry-pipe sprinkler system and preaction sprinkler system are used as secondary fire suppression systems. The only part of Nemours Children's Hospital as a part of The Nemours Foundation requiring fireproofing is the metal decks in the central energy plant and loading dock data center.
The telecommunications systems in Nemours Children's Hospital as a part of The Nemours Foundation are very elaborate systems for security, child monitoring, emergencies, and elevator overrides. Along with these systems, the hospital has an intercom/paging capabilities like most typical hospitals have. Payphones are provided near the waiting rooms for the convenience of the patient's friends and family. Overhead projectors and televisions are used in the conference rooms for meetings and presentations. Televisions are also provided in the waiting rooms for leisure and in operating rooms for surgery.
Special Systems
Nemours Children's Hospital as a part of The Nemours Foundation has lead encased rooms for radiation protection. These rooms have lead glass, sheets, strips, and plates to ensure the radiation is contained in that specific room. Additionally, the hospital has audio booths for audio exams. The booths are prefabricated with adjoining control rooms. Special details adhering to acoustical standards are closely followed to guarantee the success of these rooms. Also, the interior wall systems throughout the hospital are constructed with noise barrier assemblies. These modular panel designs are installed in an effort to provide privacy for each individual room.
