Orlandos City Energy Project Im delighted to see you here and be
launching this ambitious and tremendously exciting project!

City Energy Project City of Orlando / Institute for Market
Transformation Our vision is to become the most environmentally
friendly, socially and economically vibrant city in the Southeast,
if not the entire U.S. Mayor Buddy Dyer Energy & Green
Buildings To reduce our energy consumption, we need to address
buildings. Cities will lead because they are building
dominated.
Building in Orlando account for 70% of CO2 emissions according to
the 2012 GHG report Source: Laitner Orlando ranks in Top 50 cities
for Green Buildings Goal: 50% reduction in Municipal electricity
consumption by 2030
Goal: 100% of Municipal electricity comes from renewable sources by
2030 Objective: 5% of energy derived from renewable sources by 2017
Benchmarks: 2010 renewable energy produced: 7,423 kwh Goal: 50%
reduction in Municipal electricity consumption by 2030 Objective:
10% reduction in electricity used by 2017 from 2010 levels
Benchmarks: 2010 cumulative electric cost: $20.7M 2010 electricity
consumption: 224M kwh DOE Better Buildings Challenge

approximately $1.1M.2.3M kWh actual reduction! Second, in almost
every instance, sites that are past the initial 12 month reporting
period are seeing additional savings above and beyond the first
year.This is a direct result of having controls provide actionable
information, and continuously commissioning these systems. and data

*50% paid for through energy efficiency savings! How can we spur
energy efficiency Throughout our communities? CITY ENERGY PROJECT
is a groundbreaking national initiative to improve the
energyefficiency of existing buildings in 10 major American cities.
Thepartnership between the City Energy Project and the
participatingcities will support bold solutions that can be
replicated by othermunicipalities nationwide and around the world
to advanceeconomic development and reduce pollution. Orlandos
potential: $55M annually savings 340,000 tons of CO2 reduction OR
Reduce emissions generated by 17,000 homes Big bold effort And what
are those tools. Here is the CEP Framework
And what are those tools?Here is the CEP Framework.There are four

Energy Star is not involved in advocating for or designing
benchmarking and disclosure mandates, but does provide technical
assistance to jurisdictions with mandatory benchmarking
requirements in place. More than 15 billion square feet of
commercial space has been voluntarily benchmarked in the past
decade Top performing buildings are eligible for Energy Star label
recognizing the top 25% of energy-efficient buildings nationwide
Washington, DC is requiring Energy Star Target Finder scores for
new buildings Stakeholder Engagement & Education
