State Building Case Study  \nCost-Effective Greenhouse Gas Reductions via Whole-Building Retrofits:  \nProcess, Outcomes, and What is Needed Next  \nFor more information, [please visit www.esbsustainability.com](please visit www.esbsustainability.com)  \nRocky Mountain Institute  \nOVERARCHING MESSAGE  \nThere is a compelling need as well as an economic case for reducing greenhouse gas emissions in existing buildings. The Empire State Building case study providesan example of how this can be done. However, significant challenges remain that must be addressed in order to quickly and cost-effectively capture the full greenhouse gas reduction opportunity for building retrofits on a  \nwidespread basis.  \nPRESENTATION OVERVIEW  \nI.  Motivation: The retrofit of the Empire State Building was motivated by the owners desire to reduce greenhouse gas emissions, to demonstrate how to retrofit large commercial buildings cost effectively, and to demonstrate that such work makes good business sense.  \nII.  Project Development Process: Using ESB as a convening point, a collaborative team was formed to develop the optimal retrofit solution through an iterative process that involved experience, energy and financial modeling, ratings, metrics, and robust debate.  \nIII.  Key Findings: At current energy costs, ESB can cost-effectively reduce energy use by 38% and save (a minimum of) 105,000 metric tons of CO2 over the next 15 years.  \nIV.  Implementation: Three different stakeholders will implement the 8 savings measures over a 5-year period using various implementation mechanisms.  \nV.  Key Lessons: Key lessons relate to strategies to maximize cost-effective savings, balancing CO2 savings with economics, and streamlining the project development process.  \nVI.  Industry Needs: Challenges in each stage of the retrofit process are hindering the achievement of long-term goals.  \nI. MOTIVATION  \nThe retrofit of the Empire State Building was motivated by the building ownership’s desire to:  \n1) Prove or disprove the economic viability of whole-building energy efficiency retrofits.  \n2) Create a replicable model for whole-building retrofits.  \n3) Reduce greenhouse gas emissions.  \nI. MOTIVATION  \n1) Prove or disprove the economic viability of whole-building energy efficiency  \nretrofits.  \nPrior to 2008, the Empire State Building’s performance was average compared [to most U.S. office](to most U.S. office) buildings.  \nAnnual utility costs:  \n• $11 million ($4/sq. ft.)  \nAnnual CO2 emissions:  \n• 25,000 metric tons (22 lbs/sq. ft.)  \nAnnual energy use:  \n• 88 kBtu/sq. ft.  \nPeak electric demand:  \n• 9.5 MW ([3.8 W/sq. ft. inc. HVAC](3.8 W/sq. ft. inc. HVAC))  \nI. MOTIVATION  \n1) Prove or disprove the economic viability of whole-building energy efficiency  \nretrofits.  \nWith a $500 million capital improvement program underway, ownership decided to re-evaluate certain projects with cost-effective energy efficiency and sustainability opportunities in mind.  \nCapital Budget Adjustments for Energy Efficiency Projects  \nTotal ESB Cap ital Budget (million $)  \n120  \n100  \n80  \n60  \n40  \n20  \n\n|  |  |  |\n| --- | --- | --- |\n| 2008 | Sum of adds / changes / deletes | New Capital |\n| Capital\u003Cbr>Budget for | = +$13m | Budget w /\u003Cbr>Efficiency\u003Cbr>Projects = |\n| Energy\u003Cbr>Related |  | $106m + 38% Energy |\n| Projects =\u003Cbr>$93m+ 0%\u003Cbr>Energy |  | Savings |\n| Savings |  |  |\n\n0  \nI.
