3 I. Purpose Aldine Independent School District Energy Conservation Plan To institute a program for the efficient management of energy consuming equipment in the district s buildings, without imposing hardships on the energy user. House Bill 3693 section and Senate Bill 12 requires the board of trustees to establish a goal to reduce the school district's annual electric consumption by five percent each state fiscal year for six years beginning September 1, Section requires the district to report the metered amount of electricity, water and natural gas consumed and to make that information publicly accessible on the district s website. II. Objective To significantly reduce energy waste and to maintain an appropriate rate of increase of energy consumption, based on growth and facilities expansion. Provide a healthy and comfortable environment for students and staff in the most energy efficient manner. Evaluate energy use and cost and develop and implement practices to improve the efficiency of the district s energy users. Raise the awareness of energy conservation among the entire Aldine I.S.D. community. To use our water resources in and efficient manner. To instill good stewardship of the resources entrusted to Aldine I.S.D. III. Scope A. This program outlines the action to be taken to implement a program of management for the heating, ventilation, air condition (HVAC), lighting and water resources, to reduce wasted energy and water in all facilities of the school district. B. This program covers the principal, faculty, staff and students and central office personnel involvement. C. This program also outlines the analysis, evaluation, and reporting of the program s effectiveness annually. 3

4 IV. Components of the Program A. The program will be organized in the following major areas. 1. Schools participation 2. Rebate and recognition 3. Building operation and other operations a. Maximum and minimum temperature setting b. Heating, air conditioning and lighting on and off time c. Blackout program d. Water Conservation 4. Summer Shutdown 5. Central Office support a. Principals and Teachers b. Maintenance c. Food Service d. Buildings & Properties e. Athletics 6. Glossary of Terms B. Details For this program to be effective every employee starting with the Superintendent and the students must be active participants. 1. School participation a. Include Energy Conservation in the science curriculum for all grades. b. Develop a school Energy Conservation Committee that would meet twice a year to set goals for the school and develop ideas that will involve student participation, such as the Student Watts Watcher Program. c. Recognize and reward campuses for their energy conservation practices according to the table on page 6 of this document. d. Understand that each principal and the support facilities administrator are responsible for the energy consumption of his/her building. 4

5 e. Steps should be made to ensure all of the air conditioning, heating and lighting systems controlled at the campus are turned off at the appropriate time. It will be communicated to the Principal by phone and by when these systems are found left ON during after hour inspections. 2. Rebate program The Energy Reduction Rebate Program is designed to reduce the level of energy consumption to an appropriate level. The district will rebate a portion of the dollar savings back to those schools that show an energy usage reduction using kilowatt per square foot as the determining criteria. This program will begin with the school year, using as the base year for comparative analysis. These rebates will be awarded based on the chart on page 6 of this document. The first annual rebates will be given in August In addition to the annual rebates, each month one campus with the largest energy reduction using kilowatt per square foot will be awarded $1, These monthly rebates will be awarded based on the power provider s billing cycle a. Schools will be permitted to use their funds for agency and campus improvement needs. (i.e. landscaping, equipment, etc.) b. The monthly usage reports will be made available on the district s website as required by House Bill c. Temporary classrooms are the only exception to the district s unoccupied set points. Due to the heating and cooling capacity of these units, exceptions to the norm are necessary to ensure a comfortable and healthy learning environment. The unoccupied set points will be 64 degrees Fahrenheit for heating and 78 degrees Fahrenheit for cooling. During the summer months when these temporary classrooms are not being used they should be switched to the OFF position for energy conservation. 5

6 d. Schools will receive rebate based on the following energy reduction table. Category 1 High Schools 15% and up reduction in kilowatt/square foot $6,000 10% - 14% reduction in kilowatt/square foot $4,500 6% - 9% reduction in kilowatt/square foot $3,500 4% - 5% reduction in kilowatt/square foot $1,500 1% - 3% reduction in kilowatt/square foot $1,000 Category 2 W.T. Hall High School, Carver High School and Ninth grade schools 15% and up reduction in kilowatt/square foot $6,000 10% - 14% reduction in kilowatt/square foot $4,500 6% - 9% reduction in kilowatt/square foot $3,500 4% - 5% reduction in kilowatt/square foot $1,500 1% - 3% reduction in kilowatt/square foot - $1,000 Category 3 Middle and Intermediate Schools 15% and up reduction in kilowatt/square foot $4,000 10% - 14% reduction in kilowatt/square foot $3,000 6% - 9% reduction in kilowatt/square foot $2,500 4% - 5% reduction in kilowatt/square foot $1,000 1% - 3% reduction in kilowatt/square foot $700 Category 4 Elementary schools, EC/PK schools and all other facilities 15% and up reduction in kilowatt/square foot $3,000 10% - 14% reduction in kilowatt/square foot $2,000 6% - 9% reduction in kilowatt/square foot $1,500 4% - 5% reduction in kilowatt/square foot $800 1% - 3% reduction in kilowatt/square foot $500 6

7 3. Building Operations a. The occupied temperature setting district-wide is degrees cooling and between degrees heating b. The unoccupied temperature setting district-wide is 95 for cooling and 45 for heating. c. Temporary classrooms are the only exception to the district s unoccupied set points. Due to the heating and cooling capacity of these units, exceptions to the norm are necessary to ensure a comfortable and healthy learning environment. The unoccupied set points will be 64 degrees Fahrenheit for heating and 78 degrees Fahrenheit for cooling. During the summer months when these temporary classrooms are not being used they should be switched to the OFF position for energy conservation. d. Optimum start/stop will be used where applicable. Optimum start/stop analyzes information and attempts to have conditioned space at set point at the scheduled time. Air conditioning and heating standard default start time for all categories will be 6:00 a.m. and the standard default shutdown times are listed below by category. High Schools and Ninth Grade Schools 4:30 p.m. Middle and Intermediate Schools 5:00 p.m. Elementary & EC/PK Schools 4:30 p.m. HVAC request should be submitted by the campus for any air conditioning, heating and lighting needs outside the schedule for each of the above categories. When events such as extended day and tutoring are consistent and reoccurring for a range of dates, a single HVAC request may be submitted by the campus to include the entire date range. The Energy Manager can assist in the proper procedure for scheduling. e. Parking lot lighting shall be turned on no earlier than 15 minutes prior to scheduled employee or staff arrival time. Lights are to be turned off in the morning when the sun rises, but not later than 7:30 a.m. They may be turned back on for fifteen minutes as the custodians are leaving for the night. 7

8 f. Parking lot lights shall remain on during any school night function at the school. However, schools with parking lot lights controlled by an energy management system should always request them along with air conditioning and heating systems for events outside the standard default operating times. g. All requests for heating, cooling and lighting must be approved by the principal and the request must be made by the principal and or his/her designee. All air conditioning, heating and lighting request should be made at least 5 days prior to the event. When request are made after 3 days prior to the event the campus will be held responsible for any overtime required to turn these systems on. All events requiring air conditioning, heating and lighting require a request to be submitted. h. Continue the district total blackout program after the custodians leave. i. Assign the head custodians the responsibility of checking the building at night to assure that all equipment that should be off is off. j. Where only portions of a facility is occupied, try to restrict A/C and heat and lighting to that section. k. When requesting HVAC for after hours events only request the spaces needed and when possible l. Close doors and windows between conditioned and unconditioned areas. m. Refrain from using electric heaters and individual fans when the normal heating and cooling systems are operating. n. Keep walls, windows and lights clean for better reflection of lights. o. Check the operation of exterior door periodically to be sure they are closing properly, if not, send in a work order. 8

9 p. All air conditioning systems at all campuses should be turned off during the summer months except in the following areas, under the following conditions: 1.
