CSU Ballroom Summary Report

SECTION 1. SUMMARY 1.2.a. Background

Minnesota State University, Mankato (MSU) is located in the south-central region of the state on a bluff above the Minnesota River approximately 75 miles from the Twin Cities of Minneapolis and St. Paul. The Mankato area is a regional economic center with a population of approximately 50,000. MSU was founded in 1868 as Mankato Normal School with 27 students. Now a comprehensive university, MSU serves approximately 13,000 students. Most are Minnesota residents, but the University's strong academic programs and excellent faculty attract students throughout the United States and from more than 60 other countries. Faculty and staff number approximately 1,300. The original "Valley" campus was located in downtown Mankato. In 1959 the first buildings were completed on the new "Highland" campus, and in 1978-1979 the campus was consolidated into the Highland area. Currently total square footage on the MSU campus is approximately 2.5 million. Alumni now number approximately 90,000. The 2009 Facilities Master Plan provides the framework to accommodate continued growth within the well-established physical patterns of the campus.

1.2.b. Process

Paulsen Architects was engaged to provide the predesign document in December 2005 and an update in 2009. Through a series of interviews and meetings with the users, we were able to develop a concept that addresses the needs of MSU and the user. Our design team then developed several options with feedback from users resulting in the final document included in this study.

1.2.c. Project Scope

The goal of the project is to address and update the CSU Ballroom with the following scope of work: Architectural and Interior Design Demolition

• Remove the existing plaster ceiling and wood veneer on the walls and soffits • Remove the operable partitions • Remove the carpet panels in the lobby

New Construction

• New acoustic ceilings and soffits in the ballrooms and lobby • New carpet panels in the lobby • Replace the operable partitions • New table and chair storage rooms in each ballroom • Add new exit corridors for each ballroom • New acoustic and wood walls in the ballroom • New acrylic wall and ceiling panels in the lobby • Canopies at the existing ticket windows • Paint and install abuse resistant wall covering in ballrooms and lobby

I. MSU BALLROOM AREA

A. The three existing Ballroom air handling units (#4, #7, #9) are all the same size. Delivering 8,400 CFM each -Total = 25,200 CFM 45% Outside Air each = 3,780 CFM each x 3 = 11,340 CFM O.A. Cooling coil listed @ 38.4 tons x 3 = 115.3 tons

Listed coil leaving conditions of 55 DB/54.3 WB. Will not dehumidify the space with the large percentage of outside air for the people with the large load

B. Our Projected Cooling Loads

1) With Food-Dining Tons CFM OA CFM South Ballroom 19.64 3,519 3,000 Center Ballroom 25.78 4,540 4,000 North Ballroom 19.64 3,519 3,000

(Total of 500 people) Loads Total With Dining 65.06 11.578 10,000

(20 MAC)

2) Non Food Meeting Tons CFM OA CFM South Ballroom 28.47 4,917 4,500 Center Ballroom 37.56 6,414 6,000 North Ballroom 28.47 4,917 4,000

(Total of 1,000 people) Loads Total For a Meeting 94.5 16,248 15,000

(14.1 MAC) (Using approximately 300 CFM/ton, new systems should supply 33,000 CFM @ 45% O.A.) (7 MAC)

II. MSU BALLROOM LOBBY

A. One existing Air Handling Unit #6. Delivering 6,200 CFM (6.2 MAC) @ 24% outside air = 1,550 CFM. Cooling capacity listed @ 17.4 tons.

Existing cooling coil leaving conditions were listed at 58° dry bulb/57.5° wet bulb. These conditions will not effectively cool the space and dehumidify at the same time especially with an estimated 115 people in the space.

B. Our projected load for the Lobby is 12.27 tons, 2,508 CFM of supply air, 1,725 CFM

of outside air. 38,468 cu.ft. (2508 CFM = 15 MAC) @ 350 CFM/ton = 4,300 CFM @ 8.6 MAC.

Existing 6,200 CFM would be a good air change. The 1,725 CFM OA will be 27% OA. Meets load requirements.


III. MSU BALLROOM AREA GENERAL COMMENTS

A. All of the existing supply air and return air ductwork has duct liner, including the fresh air intake ductwork. MNSCU Standards require that the ductwork be replaced with new wrapped ducts. No liner.

The cost of duct cleaning and re-coating the interior of damaged duct liner costs the same as new wrapped supply and return air ductwork. As such, all of this ductwork will need to be replaced.

The fresh air intake ductwork should be replaced to meet indoor air quality standards for all four units.

B. The existing three Ballroom spaces have two gravity relief vents in each space. Our

recommendation will be to provide a heat recovery unit over each Ballroom for exhaust air discharge above the roof and a fresh air intake system with energy being reclaimed from the exhaust air into the fresh air through a heat recovery wheel.

IV. EQUIPMENT/LOAD REDUCTION A. The three energy recovery units that are being proposed to reduce cooling and heating

coil loads will have a payback of 2 to 3 years. (Based on a run-time of 60 hours per week.) With 30 hours per week run-time, the payback will be 4 to 6 years.)

B. Any structural revision costs and roofing patching costs are not included in the cost

estimates. C. Past MSU,M comments indicated that the Ballroom roof is in need of replacement and

should be looked at during this study. V. EXISTING EQUIPMENT

A. The existing air handling units are all past their full life expectancy of 20 to 25 years. (They are 40 years old.)

B. Valves, fittings, traps and controls are all at or over the useful life expectancy also and

should be replaced.
