Energy Management Programs in Texas Public School Districts Gavin Dillingham, PhD HARC Jennifer DuPlessis, MBA, CEM, ATEM Arlington ISD School Energy Managers on Energy Management CATEE, December 16, 2013
Why Energy Management Energy budget second largest budget item - Saves Money • $12 billion per year spent on energy; typically 1/3 is wasted - Improves Performance • Maintains room temperature • Ideal temperature for learning • 68 degrees and 74 degrees • Temperatures out of range • 14% to 18% decrease in test scores • Better indoor air quality • Improved ventilation rates • 15% increase in test scores
Study Background • In 2013, HARC issued a survey to Texas School Districts • Objective: Determine the status of energy management programs in the state of Texas; investigate how institutional factors, policies and resources influence energy usage • Method: Online survey tool • Outreach: The survey was presented to the school districts with the assistance of Texas Association of School Business Officials (TASBO), the Texas Energy Managers Association and the Texas Education Service Centers. • Participation: 60 school districts responded. All school districts were eligible to participate in the survey.
State of Energy Management Average age of school district buildings 26 years Average number of schools district buildings 33 Average size of school district 4.6 million sq/ft Old and Large Portfolios • Percent of districts • with Energy Managers • 76% • Districts with an • energy management program • 88% • Percent of districts without • additional energy staff • 42% • Average length of • energy management program • 10 years Average number of people reporting to the energy manager 2
EUI of School Districts 182 million square feet of school facilities 1.35 million MWh of energy consumed Average Hot and Humid 29 33 13 46 Highest EUI Lowest EUI
Why School Districts Start an Energy Management Program • The most cited energy champion in the district is the superintendent followed closely by the facility director
Energy Policy • 71% of district had an energy management policy
Benchmarking • 61% of districts had conducted some level of benchmarking since 1999 • 39% had undergone a benchmarking initiative in the last three years
35% have a green teams at schools in the district Behavior Management Programs • 37% receive percentage of savings back to their schools
Testing Behavioral Programs • Hypothesis: School districts with behavior management programs that include incentives will have lower energy use intensity than districts that do not have programs or that use sanctions. • DV – Energy Use Intensity • IV – Behavioral program types; CEM; District Size; District Age
Change in EUI CEMs at School Districts 6 kBTu/sq ft Number of Buildings 1 kBTu/sq ft 28 kBTu/sqft -.17 kBTu/sq ft Age of District 9 kBTu/sq ft Incentives
Why Districts with CEMs have higher EUI • Certified Energy Managers tend to be in larger school districts with fewer staff per building. • The 10 largest schools had on average 3 employees supporting energy management programs, with 40% having no supporting staff. • In total over 40% of the reporting school districts did not have any supporting staff for energy management.
