Cuyahoga County Public Library
Garfield Hts. Branch
Garfield Hts., Ohio
Tec Inc. completed MEPT engineering for the new construction of the Garfield Hts. Branch Public Library. This project was designed to LEED standards.
The close proximity of the library to the surrounding neighborhood was an important consideration when selecting mechanical and electrical equipment. An ultra low sound outdoor air handling unit and emergency generator with sound attenuated enclosure was installed within an acoustical screen to minimize disturbance to the neighbors.
An underfloor air distribution system maintains the comfort of occupants within the library. This type of system provides superior indoor air quality because supply air is delivered at the floor, then removes contaminants in the space as it rises to the ceiling. Flexibility for future space planning is also achieved simply by moving vents within the raised floor system.
The underfloor system also allows for ease of installation and future changes for the electrical and technology infrastructure.
Our lighting design firm, Tec Studio Inc. completed the lighting design for this project. The design required thoughtful consideration to maintain the LEED goals, remain budget conscious, and still provide a high level of design to meet the architectural concept for the space. With the open architecture of the space, all fixtures incorporate an individual digital address for lighting control. The nature of this type of control system allows for future changes to the open space planning, with only the need for simple re-programming. The digitally addressable controls also provide superior performance for the daylight harvesting system by allowing an individual response from each luminaire to the daylight sensors scattered throughout the space. The majority of the luminaires are fluorescent and will provide a very long lamp life and lower maintenance for the facility. The lighting power density for the project is 16% below ASHRAE/IES 90.1 requirements. In addition this project has submitted an innovation credit following the LEED credit MRC4 for Sustainable Purchasing: Reduced Mercury in Lamps through the use of T5 lamps (rather than T8).
