Lady Bird Johnson Middle School
3601 Pioneer Drive
Lady Bird Johnson Middle School, which opened August 2011, is the first net zero school in the State of Texas, the first net zero middle school in the country, and the largest net zero middle school in the country.
In simple terms, net zero means the building will produce as much energy as what it consumes from the electric grid over a 1-year period.

Renewable energy features
Solyndra PV array, 66,000 ft2 of solar panels
12 2.4 kW Skystream 3.7 wind turbines
Turbines have 12 ft rotor diameter on 45 foot high monopole towers
Monitoring via Siemens Green Touchscreen powered by QAC at http://irvingisd.siemens.greentouchscreen.com/
- Certified LEED Gold by the USGBC
- 468 geothermal wells, each 250 feet deep are connected to 105 water-based heat pumps in the high efficiency heating and air conditioning system. The closed loop system uses water to transfer heat from the building to Earth in the summer months and from Earth to the building in the winter months, reducing HVAC energy use by 30%
- Increased wall and roof insulation. Reflective roof to reduce cooling loads.
- High efficiency window glazing
- Solar shading provided by canopy on two sides of the building
- Sensors adjust artificial light levels in classrooms and corridors based on available daylight and turn lights off when the room is unoccupied.
- LED lighting
- Rainwater collection, grey water harvesting from athletics areas and collection of condensate.
- Energy Star kitchen equipment
- Pulper in cafeteria – students grind up compostable waste into reusable PULP which can be used in composting. This reduces the amount of garbage sent to local landfills by over 50%.

Lady Bird Johnson Middle School, which opened August 2011, is the first net zero school in the State of Texas, the first net zero middle school in the country, and the largest net zero middle school in the country. The net zero concept relates to energy consumption and production. In simple terms, net zero means the building will produce as much energy as what it consumes from the electric grid over a 1-year period. For the most part, the building itself produces the majority of power to operate throughout the day. At times, energy is needed from the electric grid to meet the building load, and at other times, more energy is produced that what is needed to accommodate the building load, thus resulting in power being returned to the grid.
