Building System Information:

Architecture:

The Hawthorn Building is the newest building on the Penn State Altoona Campus. It was created as the solution to the existing problem of the Computer Learning Resource Center and Campus Library sharing the same building. Before the construction of the Hawthorn Building, these two buildings took needed space away from each other. The Library now occupies its old space as well as the CLRC space, and the CLRC facility was moved into the Hawthorn Building.

The new Hawthorn Building houses 56 faculty offices and 24 classrooms, including a music rehearsal room and three computer labs/classrooms. The building consists of approximately 58,800 square feet. Of that, 10,000 square feet is devoted to a computer center with supporting offices and classrooms. The Hawthorn Building also contains general classrooms, seminar rooms, video conferencing rooms, lecture halls, the Pechter Family Music Room, a food service area, and faculty offices.

Construction:

The Hawthorn Building is a Type B fire resistive construction with automatic sprinklers throughout the entire building. The site construction began on November 28th, 2003 and the building was substantially completed on January 1st 2004. There were no major problems with site excavation or construction.

Zoning and Historical:
PA Department of Labor And Industry:

Fire Protection: Fully sprinkled

Major National Codes:
BOCA 1999 Edition:
Occupancy: Type B (Business)
Construction: Non-combustible/combustible-unprotected
Fire Protection: Fully sprinkled

Electrical:

Hawthorn Building’s power distribution system utilizes both 480/277V and 208/120V. Service is brought into the building from the utility via a 12,470V step down transformer. A 100KVA transformer is used to feed power to the 600A sub-distribution panel, which supplies the 208/120V panels. Hawthorn building uses 9 smaller step down transformers to supply power to its panel boards. The building also has 2 extra transformers that are kept onsite as extras, but they are not hooked up at this time. There is also a 35KW 408y/277V 3 phase, 4-wire emergency generator in case of power interruption.

Lighting:

Most of the Hawthorn Building makes use of fluorescent lighting and natural daylighting. Corridor spaces use daylight from the windows as a main source of light during the day, but also uses 6”, 32W triple tube compact fluorescent downlights. All doorways have a 4” triple tube 18W downlight for additional light.

Standard classroom spaces, faculty offices, server rooms, tech classroom spaces, and the seminar rooms all make use of 18 cell 3 lamp, 32 watt per lamp, T-8 recessed fluorescent lighting

The telecommunications/video conferencing classroom makes use of multiple types of lighting. General lighting is provided by a combination of a 6” 32W triple tube dimmable wall wash as well as 8” 42W triple tube dimmable downlights. Additional spotlighting is provided for the board as well as the person speaking by using par56 300W track mounted incandescent spotlights.

Lighting in the music room takes on a more decorative feel. General lighting is provided by 9 cell, 3 lamp, 40W, recessed, parabolic luminaries. It also uses 8”, 26W, double tube, CFT cylindrical, suspend pendants.

Computer labs in the 2nd floor use 8’ 32W architectural indirect fluorescent T8s. These luminaries are laid out in 48’ runs in each row. Task lighting is also provided as some of the desks via desk lamps.

Site lighting is done with architectural lantern style luminaries mounted on architectural steel poles and uses high pressure sodium lamps.

Mechanical:

The main mechanical system consists of variable volume boxes with reheat coils. These are supplied by four air handling units. Three of these air handling units supply between 17,000 and 27,000 cfm of fresh air. They also have hot water heating coils and a chiller water coils for heating and cooling purposes. The last air handling unit supplies around 8000 cfm of fresh air. It also utilizes a water heating coil, but its cooling system is different from the other three. For cooling, it uses an integrated Dx coil with an integrated condenser. This allows for cooling when the condenser isn’t running. There is also a 200-ton chiller that is used for cooling purposes, as well as a 2,200 cfm air conditioner in the main computer lab. Heating is achieved by using four 1,000,000 btu input boilers, with one of those acting as a backup unit. 15 cfm of fresh air was used as the design criteria for the classroom and conference spaces.

Structural:

Hawthorn Buildings structural system was designed under the BOCA 1999 code. It is a ridged steel moment frame with 4” slab on composite metal galvanized deck. The composite is 2” thick, and reinforced with 6x6 W2.1xW2.1 WWF. The single membrane roof is framed with steel joists with a typical size of W22 K6’s. The slab on grade is 5” thick and uses steel reinforcement. Typical columns are between W10x33 and W10x49 steel.

Fire Protection:

All of the areas in the Hawthorn Building are fitted with wet pipe automatic fire suppression sprinkler systems (either concealed pendant or upright). Each stairwell is also equipped with a standard 4” fire standpipe. The building also included emergency fire warning lights, strobes, manual pull stations, and sounding alarms. Construction provides a 1-hour fire rating on all rooms of the Hawthorn Building.

Plumbing:

The domestic water for the Hawthorn Building is maintained by using a standard water pump. Gas pumps as well as gas water heaters are located in the mechanical rooms of the building. These are used in a water recirculation system. Sanitary and sanitary vent stacks are used to collect the used domestic water.

Telecommunications:

Each classroom is equipped with high-speed Internet access, has access to a wireless access point, and is equipped with cable for television purposes. This is also true for each of the faculty offices, the music room, the conference rooms (video conference room included), computer labs, and the student lounge areas. The computer labs also have computers equipped for web cam use. The computer labs also have Windows, Macintosh, and Linux machines for use by students and staff.

Transportation:

There is 1 passenger elevator the services both the 1st and 2nd floors of the Hawthorn Building. It has a load capacity of 2,500 pounds.

Special Systems:

Both floors of the Hawthorn Building make use of occupancy censors that are used for lighting controls as well as for security purposes.
