“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.

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
City of Orlando – Leading by Example in National efforts
• DOE Better Buildings Challenge
– Working on Energy Data Accelerator
with OUC
– 6 Million SF + 24,000 LED streetlights
• Chief’s Energy Challenge
– 17 Fire Stations
• EPA National Building
Competition
– 5th place out of 5,000+ buildings
• Connect Cities
• Compact of Mayors
Orlando’s power bill:
$14,000,000 /year
Orlando 2010 Baseline
• 770 buildings:
– 121 conditioned
– 20 w/ controls
• No web based
EMS
• No graphics
• No trends
• No sub-meters
• Canned
programming
• Driving blind
ARRA EECBG Scope
• 28 buildings selected for upgrades
– Baseline utilities = $556,000/yr
• Fire stations, community centers, administration, support facilities
– 273,000 sqft total project portfolio
– Avg $/sqft = $2.06
• ASHRAE lvl 1 audit:

Old DX equipment
Standard thermostats
Handful of air cooled chillers
HPS, MH exterior lights
T12 & T8 interior lights
• ECMs:

Set up the Revolving Energy Fund
• First order of business: how can we stretch
these funds to provide long-term funding of
ECMs?
– Answer: Revolving Energy Fund
• ARRA was the seed
• Projects are self funded from energy
savings estimates
• ASHRAE lvl 1 audit required
• ASHRAE “Procedures for Commercial
Building Energy Audits” required
• All documentation is uniform and
industry standard – no proprietary
methods
• Keeps the accounting simple
ARRA EECBG Scope
• Total project spend: $1.76M
• Estimated : 25% reduction from baseline
– 1st year actual: 22.8% reduction
– 1st year savings from projected escalation = 25.8%
reduction
– Current reduction: 31%
• Total electric savings through 2014 billing:
approximately $1.1M. 2.3M kWh actual
reduction!
Forty-eight LVX 2 x 2 fixtures fed by one 25 amp circuit transporting power
and data over one Ethernet cable per fixture pic 1 of 2.
Web based EMS systems don’t look like web pages. That’s
odd…
• Often the graphics look something like this…
• AC-2. Cool. What is it though?! 5 ton split? 20 ton
RTU?
• Unit nameplate
• Bill of Materials
• As-builts/O&Ms
• Factory repair
manuals
• SEER/COP
• kW, kWh, $,
runtime
Ahh, that’s better!
Knowledge is power in the hands of the right people
Post- ARRA Annual Utility Spend Per Building
– 2nd year savings greater than first year

CITY ENERGY PROJECT
is a groundbreaking national initiative to improve the energy
efficiency of existing buildings in 10 major American cities. The
partnership between the City Energy Project and the participating
cities will support bold solutions that can be replicated by other
municipalities nationwide and around the world to advance
economic development and reduce pollution.
