“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

TRANSCRIPT

Boosting Efficiency in Buildings Chris Castro, LEED GA, CPB
Orlandos City Energy Project Im delighted to see you here and be launching this ambitious and tremendously exciting project! September 17th, 2015 Chris Castro, LEED GA, CPB Program Manager, 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
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 Chiefs Energy Challenge 17 Fire Stations EPA National Building Competition 5th place out of 5,000+ buildings Connect Cities Compact of Mayors Orlandos power bill: $14,000,000 /year
My background and history mins 770 buildings: No web based EMS No graphics No trends No sub-meters
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 Initial audit of Orlandos energy management min 28 buildings selected for upgrades
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: BACnetcontrols 16 SEER HVAC Hybrid DHW LED lighting RFQ process and scope of ARRA.3 mins 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 Total project spend: $1.76M Estimated : 25% reduction from baseline
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! 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 over one Ethernet cable per fixture pic 1 of 2.
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. For Demonstration Purposes
No Heat Sinks Front Back Web based EMS systems dont look like web pages. Thats 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 3-4 mins Ahh, thats better! Knowledge is power in the hands of the right people
3-4 mins Post- ARRA Annual Utility Spend Per Building
2nd year savings greater than first year Controls + Continuously Commissioning= CONTINUED SAVINGS 2 mins On-site Renewable Energy
Fleet Maintenance Garage 420kW installed in 2013 Fleet Lake Eola Compactor Array 11kw Installed 2014 Coming soon: Megawatt utility-scale solar farm at Iron Bridge WWTP Solar canopy / carport at Orlando City Hall 1 min Better Buildings Challenge & EPA National Building Comp.
Goal to reduce 20% by 2021 2011 baseline Reduced energy use at Leu Gardens by 45 percent! Phase 2: Citywide Energy-Efficiency Project
$18 million municipal bond 110 Buildings Total Phase I 55 Buildings Amway Center Wastewater Treatment Plants Fire Stations Community Centers ASHRAE Level II Energy Audits Goal $2.4 Million annual return Fund future EE investments Pay down the bond Moving Forward - Citywide Energy-Efficiency
ASHRAE Level 1 Walk-Through Analysis/Preliminary Audit ASHRAE Level 2 Energy Survey and Analysis ASHRAE Level 3 Detailed Analysis of Capital Intensive Modifications My next big project.Explain RLF. 3 mins Connected Cities Bring 100 U.S. Cities Online and Enable a More Resilient Urban Infrastructure Reduce energy costs, accelerate workforce productivity, and optimize taxpayer dollars. Share and learn best practices from peer cities Measure & Verify the energy efficiency savings "The City of Orlando has worked to become one of the most sustainable cities in America, and we are committed to building partnerships and sharing resources that foster positive environmental changes," -Buddy Dyer, Mayor of Orlando. LUCID Orlando Police Headquarters Coming 2016
*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 categories of change. GreenWorks Orlando Case Study: New York City
Small Businesses and Job Creation NYC Launched Energy Benchmarking, Audits, and Rx policy in 2010 as part of PlaNYC numbers: 16,000 buildings (public & private) 5.7% energy savings $267,492,147 savings 6,500+ new jobs created GDP increased 4.2% Electricity prices decreased 8.4% Greenhouse Gas emission reduced by 9.9% EPA 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
Small Businesses and Job Creation 170+ presentations and meetings since October 2014 2014 Climate & Energy Summit In partnership with OUC 2014 BOMA Energy Efficiency workshop In partnership with BOMA-Orlando 2015 Green Economy Summit In partnership with Orlando Regional Chamber of Commerce 2015 Multifamily Energy Efficiency workshop In partnership with AAGO, IREM, OUC and Duke Energy CEP policies and programs are designed to overcome those barriers
Boost benchmarking & disclosure, audits, Retro-commissioning INFORMATION GAP FINANCIAL BARRIERS INERTIA COMPLEXITY Provide financing tools; Align lease structures Encourage improved operation, cost effective upgrades, and code enforcement Lead by example by city government & challenge programs For the City of Orlando, Sustainability is a journey, not a destination!
