Benchmarking Policies

Recently Published Resources
5
Drivers of Developing the Handbook
• Increasing number of benchmarking policies and programs around the country
• Cities and states need consistent ways to analyze the impact of these efforts
• Benefit of deploying these resources/tools soon, as they may impact program design
• Desire to establish baselines as early as possible
• Increasing interest in measuring the energy and GHG reduction impacts of efforts
6
Use of Handbook
• Intended to provide local governments and their partners with a “how-to-guide” with clear steps and data requirements
• Set of feasible, replicable, and defensible methods
• Both primary and secondary methods
• For use in the near (baseline collection), medium, and long term
• Recognition that foundational aspect of benchmarking policies are difficult to measure
7
Barriers Benchmarking Addresses
Internal Barriers: Lack of owner or property manager visibility into, or focus on, the building’s energy use
Market Barriers: Lack of transparency about energy performance among real estate professionals, tenants, investors, and underwriters
External Barriers: Lack of broader market data to support efficiency program and policy design

Logic Model

Expected Market Changes Over Time
10
Methods
Common Themes:
• Use data already collected through the B&T policies
• Relying on background and historical documents in the public domain
• Obtaining feedback from key stakeholders and partners
Ways to Evaluate:
• Market transformation
• Energy use impacts
• GHG emissions impacts
• Job creation
11
Market Transformation Methods
Logic model and market transformation indicators (MTIs) provide a method for assessing the degree to which the policy is:
a) Changing market perceptions, structures and operations related to energy efficiency
b) Motivating market actors towards increased energy efficiency in the overall market
Survey and interview instruments are included in the Handbook

Energy Savings Methods
Gross Impacts: The change in buildings’ energy usage over time inclusive of actions taken to reduce energy consumption as well as their participation in other energy efficiency activities or programs.
Primary: Analysis of iterative EUI outputs from Portfolio Manager of reporting buildings
1. Identify baseline and reporting year2. Determine which buildings have data in baseline and reporting year3. Calculate average EUI by building segment for both baseline and reporting year4. Calculate total gross impacts for all buildings through a weighted average5. Repeat steps 1-4 for next annual increment6. Sum gross energy impacts for each year to determine impacts over desired period7. Develop analysis categories.
Secondary: Augmented analysis of iterative EUI outputs
14
Energy Savings Methods
Net Impacts: The subset of measured gross energy changes attributable to the B&T policy. That is, the net savings after taking into account natural market forces, common practice, and the impacts from other local, state, federal, and utility energy efficiency programs and tax credit initiatives.
Primary: Historical tracing and structured expert judgment
Secondary: Quasi-experimental design such as regression discontinuity and comparison city
15
GHG Emissions Method
GHG emissions data can be sourced directly from Portfolio Manager
1. Collect emissions data for baseline and reporting year in each building
2. Normalize emissions data by building floor area for each year
3. Calculate difference from this adjusted baseline
16
Job Creation Methods
17
NYC Example
• Local Law 84
• Enacted in 2009
• Buildings over 50,000 square feet
• Affects over 2.8 billion square feet
• First year of data collected in 2010
• Chance to apply the Handbook methods

Moving Forward
Measuring the impact of policies can help to understand their success or failure and deciding whether to continue, expand, or replicate them• Rigorously assessing energy efficiency impact of policies can
help ensure that their contributions to state energy savings can be recognized
• Consider early interviews of key stakeholders at the time of policy initiation to set a baseline for measuring future market transformation
• Use the data collected through benchmarking to measure changes in energy performance over time
• Begin measuring relationship between energy performance and building valuation to set a baseline for future changes
