Challenges Facing Commercial Facilities

• Rising energy costs
• Aging infrastructure
• Lack of necessary capital
• Corporate Social Responsibility (CSR) initiatives
• Climate change and emissions reduction strategies
• Carbon regulation

4
Background Reduction Goal for 2017

• To meet PlaNYC, GHG Emissions from NYC buildings
  and operations must be reduced by
• 1.68 million metric tons CO2e from FY2006 level.

1.68 Million Metric Tons CO2e
30 Reduction from FY06
5
Background Planning Approach and Process

• GHG reduction planning from municipal assets
• -Data Collection DCAS database, interviews,
  technical studies
• Assumptions Baseline growth scenario, inflation
• Development of the citywide GHG reduction model

• Financial Analysis
• -Apply standard Net Present Value approach to GHG
  reduction model
• Establish financial criteria/priorities (e.g.,
  minimum paybacks)
• Sensitivity Analysis

• Implementation Plan
• -Capital Projects
• Operations and Maintenance
• Key Support Activities

6
GHG Emission Reduction Model Methodology

• Development of Energy Consumption Database
• Consolidate consumption and expenditure
• Assign building type codes
• Merge data from other databases
• Delete Leased properties
• Disaggregation of Energy Consumption to End Uses
• Estimation of Technical Potential

7
GHG Emissions Reduction Model Results

• Total Reduction 1.68 million metric tons per
  year
• Total Savings 306 million per year
• Total Cost 2.3 billion

  Year
• Total Savings 306 million per year
• Total Cost 2.3 billion

15
Financial Analysis Approach

• Standard Net Present Value approach
• 25-year planning horizon
• Set implementation schedules for 10 years
• Measure effects decay over time
• Base Case Assumptions
• Energy price inflation City budget
  outlook to 2012 3 thereafter
• Construction cost inflation 2.5
• All capital projects funded by borrowing

16
Financial Analysis Results

• Program breaks even on cash flow basis 2013
• Program breaks even on cumulative basis 2015
• Net Present Value over planning horizon
• 625 million
