Background
Grants from Georgia Environmental Facilities Authority (GEFA)
plans for upgrades/retrofits, geothermal, wind, solar
Savings to Energy Efficiency and Renewable Energy Revolving Loan Fund
for upgrades and renewables until buildings are carbon-neutral/zero consumption
baseline is 2008 energy use
Then, savings to Tybee Energy Loan Fund and the Property Assessed Clean Energy
Financing Program

Timeline
2010 (Jul/Aug)
retrofit buildings: insulation, thermostats, lighting
install ground loop for geothermal system
develop best practices (City Green Team)
2012 (Jun)
hook City Hall into
geothermal system
2014 (Aug)
correct City Hall geothermal controls

2008 baseline
2010 retrofits
2012 geothermal

Geothermal only decreased usage in summer months; correction in Aug. 2014
Zoning issues still remain; space heating? move meetings and AV equipment?

Lessons Learned
Energy efficiency measures can work!
Monitoring and maintenance is vital.
Projects need independent oversight to ensure proper installation, functioning, and maintenance.
Consider commissioning
energy management or issuing performance contracts for large projects.
