The Irving Elementary School was designed as a Community Concept. Educational pods are analogous to Neighborhoods. Each neighborhood square is naturally lit with clerestory light. Each neighborhood has a unique color to enhance way finding and community identification.
Circulation areas were analogous with streets. Unique floor patterns and ceiling features create memorable nodes at key intersections to enhance way finding.
Common use spaces are centralized similar to a downtown and the administrative offices serve as an adjoining government center. Centralized common use spaces reduced travel distances and allowed for night time utilization while securing the remaining school.
Natural light, colorful vibrant interiors, way finding, and limiting travel distance were all priorities in this Community Concept.
The building light fixtures mainly utilize energy efficient T8 lamps and electronic ballasts. In areas where architectural features are present, the use of energy efficient compact fluorescent lamps and electronic ballasts are utilized. There are no incandescent lamps in use within the facility.
The multipurpose room takes advantage of dimmable fluorescent lighting and a central electronic lighting control system to accommodate the space for use as a lunch room as well as other varied performance activities.
Exterior lighting utilizes metal halide lamps and energy efficient pulse start ballasts.
The gym utilizes new technology T5HO fluorescent lamps in a traditional 2- x 4-foot sized light fixture. This gives the school the "instant on" capability not available when utilizing HID lamp sources. In addition, the lumen depreciation, lamp life, color rendering and energy savings are all improved utilizing the T5HO lamp technology.
The majority of the spaces within the building utilize automatic lighting control via motion sensors. This produces a substantial energy savings to the district.
The courtyard spaces at the classroom entrances utilize linear indirect/direct fluorescent lighting hung by aircraft cable. These spaces are controlled by occupancy sensors as well as day-lighting sensors to take advantage of the natural lighting when it is available.
The HVAC system included high efficiency, hot water boilers for the central heating and a high efficiency air cooled chiller for the central cooling. Variable air volume systems were used to condition most areas. Air to air heat exchangers were used to pre-condition the ventilation air. CO2 sensors were used to provide demand control ventilation in high occupancy areas.
The overall energy efficiency measures in the building provide a projected 36.7% energy cost savings over a 'code base' building as modeled by an independent energy audit. The school district will receive an $81,600 Energy Efficiency Incentive from the utility company for the implementation of these measures.
