The new headquarters for Korte & Luitjohan Contractors, Inc. includes 9,000 square feet of office space and a separate 16,000-square-foot warehouse maintenance building that serves a multitude of uses. The entire complex is located on 10 acres in Highland, Illinois.

The office facility has a total of 13 private offices for the President, General Manager, Project Managers and Estimators, with adjoining open layout for assistant project management and accounting departments. The office facility also includes a conference room which comfortably seats 12 people, a plan room for subcontractors and suppliers to review plans to prepare pricing, a fully functioning kitchen and break room including Energy Star rated appliances, and a training room that accommodates approximately 50 people. This space also includes a 1,000-square-foot basement which houses the facility's geo-thermal pump units, air handlers, and miscellaneous storage. Airlocks control exterior air flow. Heating and cooling for the office building is divided into seven zones and controlled by programmable thermostats.

The warehouse maintenance building includes an office for the shop foreman, a break room for the service personnel, storage of equipment parts, small construction equipment and tools, service garage for heavy equipment and company vehicles, a wash bay, and storage area for materials for construction projects.

Both buildings were built with "Green" building practices and materials in mind. The exterior of both buildings, including the perimeter basement walls were constructed utilizing Insulated Concrete Forms (ICF). The ICF walls of the buildings have an R-value over 25. The roof decks are constructed of Oriented Strand Board (OSB) instead of plywood, covered by a white, Thermoplastic Polyolefin (TPO) single-ply membrane to reflect solar heat, and have an R-value of 30. The buildings contain recycled components including carpeting, shelving, ceiling tile, steel joists and studs, roof decking, doors and door frames, OSB wall sheathing, ICF wall forms, ISO roof insulation, TPO roof membrane. Recycled concrete backfill and subgrade were used as site materials.

Energy efficient "T5" fluorescent lighting illuminates 99.9% of the buildings, and while the office utilizes motion detectors to switch off many of the lights when not needed, the shop utilizes 21 skylights to reduce the need for light during the day.

All windows have Low "E" glass with encapsulated blinds. Plus most feature an operable lower unit to allow fresh air and reduce HVAC demand during the fall and spring seasons.

The warehouse is heated with radiant heat in the floors produced by a 99% clean burn waste oil boiler. The company is able to reuse the waste oil generated by its heavy equipment and trucks over the course of a year to heat the warehouse. The remainder of the company's waste oil is sold to a recycler.

Storm water is collected in an excess capacity detention pond for use in washing equipment coming in for maintenance or repair, and for filling water trucks and trailers for construction site needs.
