Commercial

The growing number of computers and other sophisticated electronic equipment in the workplace has dramatically changed mechanical requirements for commercial and office buildings. Many companies now require office space equipped with high capacity HVAC systems, precise humidity and temperature controls, halon fire protection, and other specialized systems.

The John E. Green Company has extensive experience with all types of commercial and office building projects. We undertake many projects on a design/build basis, planning mechanical and fire protection systems to meet the criteria of owners and architects.

On all projects, John E. Green emphasizes value engineering, consulting closely with the owner's engineers to ensure maximum savings and efficiency in the design and installation of all mechanical systems.

The International Headquarters for K-Mart Corporation is designed on a unique modular configuration. John E. Green Company served as mechanical contractor for a major expansion that added nine new modules to double the facility's total square footage. Each module has an independent air conditioning and heating system.

The Comerica building in Auburn Hills serves as the computer nerve center for the bank's total statewide operations. John E. Green supplied all major mechanical systems for the 3-story building, including boilers, air conditioning units, cooling towers, and a 4,000-head sprinkler system. Energy-efficient variable speed drives were installed on all air-handling equipment. The drives were FCC rated to safeguard against radio frequency emissions that could affect the computer databanks.

John E. Green provided complete design/build services for mechanical systems in the Ann Arbor headquarters for Group 243 advertising agency. The unique interior plan of the building allowed insufficient space for the plumbing, heating and ventilation systems as originally specified. We re-designed the entire system to fit the available space.

Temperatures and humidity in the Michigan Bell Computer Center must remain constant within ±1° to protect sensitive electronic equipment. We installed a special Liebert air conditioning system engineered to those tolerances. We also provided a halon fire protection system for this area.

The John E. Green Company has provided all mechanical systems and fire protection for several construction phases of the Dow Corning headquarters in Midland, Michigan. Our projects have included a new laboratory building and two new office buildings, one of them the Corporate Headquarters shown here.
