The DeWitt High School in DeWitt, Mich., chose precast concrete wall panels to improve heating and cooling efficiency and save on construction costs. The VersaCore panels saved the school district approximately $1.25 million, according to Project Director Gary Ciampa of Clark Construction, the project’s contractor. The panels were also chosen for their wear during harsh weather conditions, as Ciampa said the material had to cooperate with the cold Michigan winter, during construction. Extended panels were chosen to help the school cope with water damage and accidental impact.

Gym breathes fresh air
Niles North High School in Skokie, Ill., is nearly 40 years old, but it has become the school of the future with a new $110 million, three-phase renovation that included the installation of 1,500 linear ft. of Comfort-Flow fabric duct. The new duct work was installed in the school’s 40,000 sq. ft. gymnasium, which houses a dividable gymnastics room, wrestling room, and a main gym with two balconies that are regularly partitioned off. The new fabric duct will allow for 15% of the total air flow through its factory-engineered fabric, limiting dust build up, while the other 85% of airflow will be dispersed through two linear mesh vents that run the entire length of the duct.

Historic building gets new life
Detroit’s newly remodeled national landmark building, the Cadillac Palace, is now the home to many state of Michigan agencies, after the addition of packaged, self-contained, water-cooled air conditioning units with variable air volume (VAV) conditioned air distribution. Originally completed in 1923, the former General Motors building is 1.2 million sq. ft. and had been using 1,860 window air conditioners and hundreds of spot cooling systems to cool the building. Model SCWB water-cooled, self-contained units were chosen, rated at 65 tons each. The building design called for 68 units, with four on each of the 15 floors with an additional six units serving the Annex wing. The duct system is a dual-duct design, with ventilation air distributed through the building, by approximately 1,400 VariTrane VAV terminal boxes. The Tracer Summit system was added to control the self-contained cooling units and the air-distribution system, managing the cooling plant for computer rooms, and the building-wide steam-heating system as well.

Automatic door opener is a low-energy operator that automatically opens the door while using a floor closer to hang and close the door. The Model 2900 is ideal for doors that are too heavy to be controlled by a traditional low-energy operator and for low to moderate traffic applications where ADA accessibility is required. By using balanced pivots, the Model 2900 only needs to overcome the force of the spring of the floor closer, allowing it to control the heaviest of doors. The unit is available for both offset- and center-hung doors, in models to accommodate either the push or pull side of the door, and in deep reveal and double egress options.

School lock in
The University of California, Los Angeles, retrofitted classrooms in its historic Haines Hall with LockLink standalone electronic access-control locking system.
