Building Energy Performance Standard

 
On April 1, 2021, the County Executive transmitted the Building Energy Performance Standard legislation to the Council.

The BEPS legislation ( Bill 16-21 ) was introduced during the May 4, 2021 County Council session. The Council held a public hearing on the bill on July 20, 2021 ( watch it here). Written testimony can still be submitted here until July 27, 2021.

In December 2017, Montgomery County declared a climate emergency and accelerated our community-wide climate goals to be carbon neutral by 2035. The residential and commercial building sectors combine to contribute 50% of greenhouse gas emissions in Montgomery County. The County is proposing a variety of programs and policies to mitigate emissions in new and existing buildings, including a Building Energy Performance Standard for commercial and multifamily buildings.

What is BEPS?

Building Energy Performance Standards (BEPS) are policies that establish performance levels for buildings and drive all buildings that BEPS covers to achieve these levels in the long-term with required progress at regular intervals in the interim. A BEPS sets a minimum threshold for energy performance for existing buildings, which are based on and measured against a building’s demonstrated energy performance, as shown in their benchmarking data. See IMT’s primer on BEPS.

 

Stakeholder Workgroup

In early 2020, DEP engaged stakeholders in a working group to vet policy elements of a Building Energy Performance Standard. Participants included the commercial and multifamily building communities and those that serve them including advocacy groups, utilities, energy contractors, and County government representatives. During the stakeholder work session meetings, attendees reviewed building performance policy models adopted by other jurisdictions, including Washington, DC, New York City, and St. Louis, and developed recommendations on a BEPS policy that balances the challenges of a climate emergency with the realities of the County’s varied building stock.

In pursuing building energy performance standards, Montgomery County was one of four jurisdictions selected for the 2020 cohort of the City Energy Project, a national initiative from the Natural Resources Defense Council and the Institute for Market Transformation that supports innovative, practical solutions that cut energy waste, boost local economies, and reduce harmful pollution. In Montgomery County, the City Energy Project technical support team has assisting in the development and implementation of the first-ever BEPS policy at the county level.

Proposed Policy Elements of BEPS in Montgomery County

The County’s proposed BEPS legislation incorporates the following components:

BEPS POLICY OVERVIEW

  • The County intends to develop BEPS that aligns with goals for climate and racial/social equity, balances flexibility with immediate action, provides certainty and transparency for building owners and tenants, and spurs jobs and economic growth. 
  • Covered buildings are grouped by building type and a long-term performance standard is created for each building type. 
  • Every 4 years, buildings are evaluated as to whether they are meeting interim targets: calculated as straight line from baseline to final standard 
BEPS Trajectory Model

BUILDING PERFORMANCE IMPROVEMENT PLANS

  • If a building cannot meet the Interim or Final Performance Standards, the County can accept a Building Performance Improvement Plan 
  • The owner must meet the actions and timelines in an approved Building Performance Improvement Plan to be considered “in compliance” 
  • Plans are reviewed by an Advisory Board with technical expertise

METRIC

The stakeholder work group recommends that the metric buildings are measured against is Normalized Site Energy Use Intensity (EUI), a measure of how efficiently a building is using energy relative to its size. The benefits of using this metric include:
  • Measuring energy use directly controlled by the building owner
  • Easy to understand
  • Can be normalized for weather and operations, such as density and operating schedule
  • Readily available in ENERGY STAR Portfolio Manager for reporting, which is consistent with Benchmarking Law requirements
  • Favors electrification—a key strategy for reducing community-wide GHG emissions
The County also plans to provide a “credit” for onsite solar generation against performance standard performance to incentivize commercial solar installations.

COVERED BUILDINGS 

As the benchmarking program phases in various buildings by their square footage over time, buildings will be added to the BEPS program in following groups:
  • County buildings and Groups 1 & 2: currently covered by Benchmarking Law: County and private-owned nonresidential buildings 50,000 gross square feet and larger;
  • Group 3: County and privately-owned nonresidential buildings 25,000 to 50,000 gross square feet, and buildings previously exempted by the Benchmarking Law;
  • Group 4: Residential buildings 250,000 gross square feet and greater;
  • Group 5: Residential buildings 25,000 to 250,000 gross square feet.

PROPOSED TIMING 

BEPS Proposed Timing
  • 2021: Legislation passes; establish Advisory Board; perform technical analysis to develop BEPS baseline
  • 2022: Establish BEPS baselines for County, Groups 1 & 2 buildings through regulation; Group 3 & 4 submits first benchmarking reports
  • 2023: Group 5 submits first benchmarking reports
  • 2026: First Interim BEPS standard for County, Groups 1 & 2 buildings
  • 2028: First Interim BEPS standard for Group 3 & 4 buildings
  • 2029: First Interim BEPS standard for Group 5 buildings
  • 2030: Second Interim BEPS standard for County, Groups 1 & 2 buildings
  • 2032: Second Interim BEPS standard for Group 3 & 4 buildings
  • 2033: Second Interim BEPS standard for Group 5 buildings
  • 2034: Final BEPS standard for County, Groups 1 & 2 buildings
  • 2036: Final BEPS standard for Group 3 & 4 buildings
  • 2037: Final BEPS standard for Group 5 buildings
 

Future Regulations

While the proposed legislation outlines the parameters of BEPS and creates a framework, some facets will be set via regulation to be established at a later date (by June 2022, as proposed). These include:

  • Building type groupings with shared characteristics that facilitate the implementation and enforcement of BEPS;
  • Numerical performance standards for each building type; Required format for BPIPs;
  • Parameters for economic feasibility or other factors that will dictate circumstances under which BPIPs will be allowed; and
  • Adjustments or assistance specific to under-resourced building sectors, such as affordable housing, small businesses, houses of worship, and non-profits.

Next Steps

The County Executive  transmitted legislation to the County Council in April 2021, and  Bill 16-21 was formally introduced to Council in May 2021. In July 2021, Council held a  public hearing on the bill and received  written testimony from the public. Committee work sessions are expected to occur in fall 2021 before the full Council votes on the legislation.

DEP will provide updates on BEPS on this webpage and through its Commercial Energy News newsletter. If you have specific questions about BEPS, please contact DEP
