The Tomball Medical Plaza, developed by Tomball Physicians Investments, LLC, is the first project in Tomball, Texas, registered for LEED CS Silver Certification. Strategies to obtain this certification included an emphasis on reduced energy consumption, community connectivity, use of building materials with recycled content and education regarding sustainable features for building tenants and visitors.

The building is oriented with its longest facades facing to the north and south, respectively, to minimize heat gain from the western sun. A roof-top array of solar panels generates a portion of the building's electricity on-site. The balance of the electrical demand is provided through a long-term renewable energy contract. The glazing system is composed of three colors of insulated glass with coatings to reject heat gain in summer and limit heat loss during winter. The three colors are arranged in a Mondrian like pattern to accent the corner stair towers, the punched window openings and the freestanding, glass curtain-wall at the covered entrance. Building commissioning upon project completion confirmed success in meeting the design intent for reduced energy consumption.

The two story building contains 54,380 square feet and occupies a 4.8 acre, Greenfield site located one block north of the Tomball Regional Medical Center and just south of the city's main street. Residential neighborhoods are located within a half mile radius, and bicycle racks and showers promote non-automobile transportation. Reserved spaces are provided for patients and staff driving hybrid vehicles.

The use of materials with recycled content includes the building's interior steel frame and the concrete reinforcing steel 100% of which comes from recycled sources.

A flat screen panel in the ground floor lobby provides a real-time display of the electrical generation of the roof-top solar array for edification of building tenants and visitors. A written manual informs tenants of the building's sustainable features and directs them in the use of the recycling center on the ground floor. Finally the maintenance staff has been instructed in the use of non-toxic cleaning materials.
