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
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.
