Rebuilding New Orleans
Green Schools New Orleans
In 2004, Global Green launched a new effort, The Green Schools Initiative, focused on greening K-12 schools. When Global Green expanded its effort in New Orleans in the aftermath of Hurricane Katrina, schools became a critical component of its rebuilding efforts there. The goal of this initiative is to create healthier classrooms and more energy efficient schools that in turn improve student performance and save money for school districts, while helping to protect the environment and reducing carbon emissions. The Green Schools Initiative has been made possible by a grant from the Bush Clinton Katrina Fund. There are two types of green schools being funded - Green Seed Schools and Green Model Schools.
The Green Seed Schools program is the first component of the Green Schools Initiative. A number of schools have been selected and designated as "Green Seed Schools." Each school receives up to $75,000 in grant funds toward energy audits, technical assistance, and improvements to increase energy efficiency, indoor air quality, and if feasible, create on-site renewable energy generation. Global Green hopes to utilize the upgrades at these schools to help educate students, teachers, and the community of how important green schools are for the rebirth of New Orleans.
GREEN SEED SCHOOL #1: A.P TUREAUD ELEMENTARY SCHOOL
A.P. Tureaud Elementary School is the first Green Seed School selected and completed by Global Green. It is located in the Seventh Ward and it was designed by E.A. Christy and constructed in 1939.
An energy audit conducted in June 2007 determined that the building is ranked in the bottom 29th percentile for energy performance with a total of 530,331 KWh of electricity and 9,271 ccf of natural gas used annually (combined Btu of 2,765,859,803). This amount of energy usage translates into nearly $80,000 per year in utility expenses. The carbon dioxide emissions were also estimated to be 15.8% higher than an industry average facility.
The Global Green upgrades will save the school an estimated $26,588 in utility costs and reduce the carbon emissions by 220,216 lbs annually. This investment will pay for itself in approximately 2.5 years. In order to achieve these savings, Global Green enacted the following:
- Solar shades were installed in classrooms to help control solar heat gain, reduce glare, and improve natural lighting within the classrooms.
- Occupancy sensors were also installed in each classroom to reduce the length of time lights are left on when classrooms are unoccupied. During the energy audit, it was observed that approximately 75% of the lights remained on throughout the evening hours when the classrooms were unoccupied. This simple retrofit can reduce annual lighting needs by 25% or more with an utility cost savings of approximately $9000 annually.
- All incandescent light bulbs were replaced with compact fluorescent lights (CFLs) with the assistance of Green Light New Orleans volunteers.
- Doors and windows were caulked and weatherstripped to reduce air leakage into the school and missing window panes were also replaced.
- In addition, Global Green took the extra step to negotiate with the building automation company to inspect the system which controls the HVAC equipment and ensure that the thermostat set points are adjusted based on current occupancy loads and seasonal schedules.
In addition to implementing these green upgrades, Global Green identified strategies that can be incorporated into routine custodial and maintenance practices at little or no cost. Some of these strategies include making sure lighting systems, office equipment, and heating, ventilation, and air-conditioning equipment is turned off or in energy saving modes during weekends and extended holiday periods; closing windows when heating, ventilation, and air-conditioning equipment are operating; changing filters each month and inspecting the boilers each quarter for safety as well as efficiency.
GREEN SEED SCHOOL #2: THE INTERNATIONAL SCHOOL
The International School, formerly known as the Andrew Jackson Elementary School, is the second Green Seed School selected and completed by Global Green. The 82-year old school is located in the Lower Garden District, and like A.P. Tureaud Elementary School, was also designed by A.E. Christy.
Utility data was collected from August 2006 until August 2007 and an energy audit was performed to guide the green energy efficient upgrades. Analysis of the utility bills showed the electrical consumption to be 552,800 KWh and the natural gas consumption to be 3,527 ccf annually (combined Btu of 2,253,000,000). The combined energy cost for this annual period was $69,908.
The Global Green upgrades will save the school an estimated $21,781 in utility costs and reduce the carbon emissions by 177,109 lbs annually. This investment will pay for itself in approximately 3.5 years. In order to achieve these savings, Global Green enacted the following:
- Higher wattage fluorescent lamps were replaced with lower wattage fluorescent lamps, thus reducing the wattage and energy used while still providing the same light output. In addition light fixtures in the Library Annex were replaced with more energy efficient light fixtures that require fewer fluorescent lamps and provide more light output.
- Solar shades were installed in all East, West, and South facing classrooms to reduce solar heat gain, reduce glare, and improve natural lighting within the classrooms.
- Occupancy sensors were installed in all classrooms and will reduce the length of time lights are left on when classrooms are unoccupied, especially from 7:00 pm to 6:30 am.
- A radiant barrier water heater blanket was also installed on a 38-gallon natural gas water heater that feeds hot water to the kitchen. This easy green retrofit insulates the water in the tank so it stays hot longer and reduces the amount of energy needed to heat the water.
- In addition, a rainwater cistern was installed at the site of the future arts and music facility to be used as an educational tool to teach students about water use and conservation. This 1500 gallon cistern will be used to capture and filter rainwater for the irrigation of nearby green spaces, raised garden beds, and fruit trees.
In addition to implementing these green upgrades, Global Green identified strategies that can be incorporated into routine custodial and maintenance practices at little or no cost. Some of these strategies include having window shades drawn down on the East side of the building during the morning and on the West side of the building during the afternoon; training the staff, particularly the custodial staff, to turn off lights in unoccupied areas such as the hallways and the cafeteria after school hours; and ensuring that the thermostat set points for the heating, ventilation, and air-conditioning equipment is adjusted properly based on the seasons and occupancy levels.
GREEN SEED SCHOOL #3: DR. MARTIN LUTHER KING ELEMENTARY SCHOOL
Dr. Martin Luther King Elementary School is the third Green Seed School selected and completed by Global Green. It is located in the Lower Ninth Ward neighborhood, a targeted recovery neighborhood. It was constructed in 2003 and was severely flooded during Hurricane Katrina in 2005. Most of the school was renovated and reopened in 2007.
Utility data was collected covering the months of June 2007 until May 2008 and an energy audit was performed to guide the energy efficient upgrades. Analysis of the utility bills showed the electrical consumption to be 1,425,500 kWh and the natural gas consumption to be 2,593 ccf annually (combined Btu of 5,134,903,500). The combined energy cost for this annual period was 124,240.
The Global Green upgrades will save the school an estimated $21,781 in utility costs and reduce the carbon emissions by 174,550 lbs annually. This investment will pay for itself in approximately 3.5 years. In order to achieve these savings, Global Green enacted the following energy saving strategies:
- Higher wattage fluorescent lamps were replaced with lower wattage fluorescent lamps, thus reducing the wattage and energy used while still providing the same light output.
- Some light fixtures were replaced with more energy efficient light fixtures that require fewer fluorescent lamps and provide more light output.
- Quartz light fixtures in the cafeteria/auditorium were replaced with LED recessed light fixtures.
- All light fixture lenses were cleaned and missing reflectors were replaced.
- Occupancy sensors were installed in all classrooms and will reduce the length of time lights are left on when classrooms are unoccupied, especially from 7:00 pm to 6:30 am.
- Daylight sensors were installed on light fixtures in the foyer and interior and exterior stairwells which get a lot of natural light.
- Gaps around penetrations in the roof and foundation were weather-sealed.
In addition to implementing these green upgrades, Global Green identified strategies that can be incorporated into routine custodial and maintenance practices at little or no cost. Some of these strategies include having window shades drawn down on the east side of the building during the morning and on the west side of the building during the afternoon; training the staff, particularly the custodial staff, to turn off lights in unoccupied areas such as the hallways and the cafeteria after school hour, and close windows when heating ventilation and air conditioning (HVAC) equipment is operating.
During the energy audit, it was discovered that the building automation system was not fully operational. Heating and cooling set points were not entered into the building automation system for some zones in the school. As a result, the facilities managers would have to manually turn on and off the heating and cooling in these areas upon request. Global Green determined that this was something that could easily be fixed by the building automation company for no additional fee.
GREEN SEED SCHOOL #4: GENTILLY TERRACE ELEMENTARY SCHOOL
Gentilly Terrace Elementary School is the fourth and final Green Seed School selected and completed by Global Green. It is located in the Gentilly Terrace neighborhood, a targeted recovery neighborhood. It was designed by E.A. Christy and constructed in 1914.
Utility data was collected covering the months of April 2007 until December 2008 and an energy audit was performed to guide the energy efficient upgrades. Analysis of the utility bills showed the electrical consumption to be 528,000 KWh and the natural gas consumption to be 8,688 ccf annually (combined Btu of 2,705,616,000). The combined energy cost for this annual period was $72,773.
The Global Green upgrades will save the school an estimated $24,021 in utility costs and reduce the carbon emissions by 195,335 lbs annually. This investment will pay for itself in approximately 3.1 years. In order to achieve these savings, Global Green enacted the following energy saving strategies:
- Higher wattage fluorescent lamps were replaced with lower wattage fluorescent lamps, thus reducing the wattage and energy used while still providing the same light output.
- Some light fixtures were replaced with more energy efficient light fixtures that require fewer fluorescent lamps and provide more light output.
- Occupancy sensors were installed in all classrooms and will reduce the length of time lights are left on when classrooms are unoccupied, especially from 7:00 pm to 6:30 am.
- Daylight sensors were installed on light fixtures in the interior hallway which get a lot of natural light.
- Solar shades were installed in all windows except for the interior hallway windows to reduce solar heat gain, reduce glare, and improve natural lighting within classrooms and offices.
- The programmable thermostats that control the HVAC system for the cafeteria were reset by switching them from “fan-on” mode to “fan-auto” mode". Also, the cooling and heating set points were adjusted to levels appropriate for occupancy loads and seasonal schedules.
In addition to implementing these green upgrades, Global Green identified strategies that can be incorporated into routine custodial and maintenance practices at little or no cost. Some of these strategies include having window shades drawn down on the east side of the building during the morning and on the west side of the building during the afternoon; training the staff, particularly the custodial staff, to turn off lights in unoccupied areas such as the hallways and the cafeteria after school hours; and ensuring that filters for the HVAC systems are changed routinely so that the systems run more efficiently.
The Model Green Schools program is the second and more ambitious phase of the Green Schools Initiative. This program will result in the creation of high performance showcase green schools including the major rehabilitation of one school and the new construction of another school over the course of the next two years.
The two Model Green Schools will receive over $720,000 (combined) worth of green upgrades and technical assistance with a goal of achieving LEED for Schools Silver certification. LEED is a third-party certification program and nationally accepted benchmark for the design, construction, and operation of high performance green buildings. The Model Green Schools program will allow for a comprehensive menu of improvements that will contribute to model green environmental conditions in the building such as improved acoustics, lighting, and indoor air quality, and greater reductions in water and energy use.
MODEL GREEN SEED SCHOOL #1: ANDREW H. WILSON ELEMENTARY SCHOOL
Global Green committed $300,000 plus technical expertise to Andrew H. Wilson Elementary School and to the Recovery School District, which has committed to achieving LEED Gold status for the school, to enable green renovations as part of the school's rebuilding effort.
The Wilson Elementary School sustained significant damage from wind and flood waters due to Hurricane Katrina and the levee failures. It is the only school in the Broadmoor neighborhood and it was designed by E.A. Christy and constructed in 1928.
The Wilson project included a complete restoration of the existing building which is approximately 37,000 sf and two additions totaling 43,000 sf. The new building additions include a gymnasium, cafeteria, and additional art and music classroom space. The existing building was renovated to modern standards while preserving the historical characteristics of the original building.

As a showcase green school, the Wilson Elementary School building incorporates more than 40 specific green measures to enhance the building’s energy efficiency and student performance. Among these green technologies are:
- Solar Hot Water system installed above the kitchen to serve 90% of the hot water demand for the kitchen as well as a 5.04 kW solar electric system.
- 12,000-gallon above ground cistern to collect and store rainwater for irrigation purposes.
- Web-based display technology that illustrates energy and water usage. The school will be able to use the data for educational purposes and to monitor carbon offset.
- Wetland habitat with 90% native species which serves as an outdoor educational classroom and to reduce the quantity and improve the quality of stormwater leaving the site.
- Interpretive signage posted in and around the school to identify and provide information about the school's green technology.
Global Green is proud to take this next step in helping New Orleans build green and feels that the Wilson School will not only serve as an important model for all of the rebuilding of schools in the city, but it will also be a stimulus for rebuilding Broadmoor in a sustainable way.
MODEL GREEN SEED SCHOOL #2: L.B. LANDRY HIGH SCHOOL
A new chapter in the history of L.B. Landry High School will be written when it opens its doors to students for the Fall 2010 school year. First dedicated in 1938 as a high school for African-American students during segregation, the high school was named for Lord Beaconfield Landry, a prominent physician who practiced medicine in the Algiers neighborhood of New Orleans for 30 years. In 1958, a new building was then constructed at the 1912 L.B. Landry Avenue site, and eventually demolished in 2008 after suffering considerable damage from Hurricane Katrina.
Global Green has committed $420,000 plus technical expertise to Landry Charter High School and to the Recovery School District to enable green renovations as part of the school’s rebuilding effort and fund visible green educational features such as a rainwater harvesting irrigation system, native landscaping, and a solar hot water system.
The new Landry will be a three-story, 210,000-square-foot facility with a total of 52 teaching stations, including career technology labs, visual and performing arts labs and classrooms for core curriculum, visual arts labs, rehearsal spaces for dance, choir, band and art, and a black box theater. It will have a 650-seat auditorium, a gym for competition and an auxiliary gym for practices. Landry school is pursuing certification through the LEED for Schools program and is currently on the cusp of achieving a Silver rating. It is expected to perform 31.6% better than code on a Kbtu basis and 27% better than code from an energy cost perspective. The energy model for the school predicts an annual electricity bill of $295,345.

Shortly after the BCKF grant was announced in 2006, the Louisiana Recovery Authority contacted Global Green and requested that the organization draft a green rebuilding policy for all major school renovations and new schools in Louisiana, whether flood damaged or not. Global Green accepted the state’s request, and worked with green building experts and representatives of the insurance industry to craft a comprehensive green schools policy for Louisiana. In January of 2007, the LRA voted to incorporate Global Green’s policy into its guidelines for schools receiving Community Development Block Grants.
In addition to creating guidelines for the state, Global Green committed to use a portion of its BCKF funds to give three green schools workshops around the state, targeting the regions that were most impacted by the 2005 hurricane season.
All three workshops were successfully completed, the first in Orleans Parish, the second in Cameron Parish - the area most damaged by Hurricane Rita, and the third and final workshop was held in East Baton Rouge Parish, which has grown significantly as a result of population migration after the 2005 hurricanes.
Other policy efforts have been focused in New Orleans. Global Green drafted a Green Schools Resolution that was passed unanimously by the City Council in May 2008. At the time, the Council directed City staff to work with Global Green to draft a Green Schools Ordinance to give the Resolution some authority, and work on this ordinance is ongoing.
Finally, Global Green formally partnered with New Orleans’ Recovery School District (RSD) in 2007, offering guidelines and ongoing technical assistance. The guidelines were incorporated into the recently adopted master plan for Orleans Parish Public Schools, which supports the U.S. Green Building Council’s Leadership in Energy and Environmental Design (LEED) Silver standard for all of its new school facilities and major renovation projects.
