Vision and Mission

• An Energy Conservation Plan will provide a cohesive solution to reduce maintenance and operations costs in the school facilities.

• A thorough district wide energy master plan will take into account

the school systems’ past, present and future energy usage.

• Obtain the ability to pinpoint opportunities for improvements to energy usage through facility upgrades, behavior management and operational improvements.

• Guilford County Schools – Program Lead– Facilities Maintenance leads process– Establish goals and mission of the program– Program oversight

• Global Facility Solutions – Energy Consultant– Assist with the development of long-term energy plan– Technical assistance with plan implementation/oversight– On-going program guidance and evaluation of results– On-site facility audits and upgrade recommendations

• North Carolina A&T – Program Assistance– Grant program– Utility bill process– Document success of program– Education component

Program Development

Establish Baseline

• Benchmark existing utility conditions.• Develop summary of energy usage for major utilities.• Establish comparison and ranking of utilities between County

School facilities.• Establish comparison to a baseline norm.• Identify schools with high energy consumption and initiate

further on-site analysis to determine potential for savings.• Assist with future utility budget analysis.

Preliminary Data Compiled by NC A&T University

• Evaluate energy profiles for all buildings (122 Facilities)• Conduct walk-thru assessments of facilities• Collect facility data (equipment, usage, etc.)• Determine Energy Conservation Measures

– Behavioral Modification– Low cost/No cost Solutions– System Intervention– Physical Upgrades

• Estimate Cost/Benefit for each ECM

Facility Audits

• Behavior Management– Change operational thinking/planning

• Low cost/No cost Solutions– Optimize scheduling, temperature setbacks, etc.

• System Intervention– Infrastructure Upgrades– Retro-commissioning opportunities

• System Design– Energy efficient building design (Design Guidelines)– Renewable energy opportunities

Develop Energy Conservation Measures

Evaluate Results

• Track utility bills monthly– Monitor utility cost versus monthly budgets.– Trend energy for reductions.– Verify and report savings.– Validate system performance.

• Program Education– Get the message out to the schools.– Educate end-users on the program goals and successes.– Develop support of end-users.– Report results by school on an on-going basis.

Reinvest Savings

• Retain Utility Savings (Self-Funded Program)– Reinvest savings into buildings and operational needs.– Invest into needed infrastructure repairs and upgrades.– Reduces the need for financing of upgrades.

• On-Going– Continuous process.– Re-evaluate based on previous results.– Adapt program to changing needs of the District and facility

technologies.
