ENERGY STAR certified buildings save energy, save money, and help protect the environment by generating fewer greenhouse gas emissions than comparable buildings. Further, a building’s energy usage and efficiency are increasingly becoming factors to attract new, and to retain existing, tenants. ENERGY STAR certification can help to increase a building’s value, and generate more income when compared to similar buildings.


The ENERGY STAR Certification and Green Leasing Grant seeks to increase the number of ENERGY STAR certified buildings, and encourage the adoption of green-leasing practices within Prince George’s County.  This effort will help support the County’s goals of reducing greenhouse gas emissions, and attract and retain high-valued tenants in the county.


Grant award funds are available to assist commercial buildings (office and multifamily housing) with achieving ENERGY STAR certification. Funds can be used to offset the costs of electric energy-efficiency, water-efficiency, natural gas and retrofitting measures, and for professional services required to achieve ENERGY STAR Certification.

Buildings receiving funding from the ENERGY STAR Certification and Green Leasing Grant are required to maintain certification for at least three (3) years, and to adopt green leasing practices that align the interests of property owners and tenants so that they are both motivated to engage in energy efficient actions for buildings.


The grant targets office buildings and multifamily housing that are built prior to March 23, 2016, that are in Prince George’s County, and are in the Pepco and or Washington Gas service territory. Definitions for eligible office buildings and multifamily housing will follow the subset of building types as defined and listed on ENERGY STAR’s list of Property types eligible to receive the 1-100 ENERGY STAR score. 


Office buildings and multifamily housing (commercial buildings) located in Prince George’s County are welcome to apply. The commercial properties should meet the following criteria:

  • Properties must be in the Pepco and/ or Washington Gas service territory;
  • Must be in Prince George’s County;
  • Have applied to ALL applicable Pepco’s and or Washington Gas’ applicable commercial energy efficiency programs, if applying for electric and/or natural gas incentives;
  • Has or will perform, at minimum, an American Society of Heating, Refrigeration, and Air-Conditioning Engineers (ASHRAE) Level 2 Commercial audit or demonstrably equivalent, if applying for electric and/or natural gas incentives;
  • Has or will apply for Energy Star Certification on or after March 23rd, 2016.

The owner of the property must:

Have a status of “Good Standing” for the current year, as evidenced by a certificate of status from Maryland State Department of Assessments and Taxation.

NOTE: Communities of single-family homes are not eligible. If the housing property is a mix of multifamily and single-family homes, the property would still be eligible as long as the single-family homes are less than 25% of the total gross floor area. 


Maximum grant award available per application: $150,000. The following incentives are available to qualified applicants:

  1. Of the $150,000, up to $50,000 will cover the ASHRAE Level 2 Audit or demonstrably equivalent and shall not exceed this amount.
  2. Grant awards to cover up to $100,000 for Electric and Natural Gas measures. Each measure will be capped at $50,000.00. 
  3. Grant awards to offset 100% of the cost of the Licensed Professional’s sign off to verify and stamp the ENERGY STAR certification application, up to $1,500. This cost will be inclusive of the $150,000 grant amount or a separate application can be submitted to cover cost of Energy Star certification.


Maryland’s Department of Housing and Community (MD DHCD) administers the income-based incentives for applicants interested in EmPOWER Maryland energy efficiency incentives.

MD DHCD Multifamily Energy Efficiency Improvement Programs - The Maryland Department of Housing and Community Development’s multifamily energy funds are restricted to affordable multifamily rental properties. “Affordable” means rental housing with existing income or rent restrictions, or housing with units that serve tenants with low to moderate incomes, as determined by the department. Multifamily rental housing may include apartment buildings, townhouses, single-family homes, single room occupancy and shared housing facilities with five (5) or more units. Eligible applicants include non-profit organizations, for-profit organizations and governmental entities.

NOTE: In order to qualify for the ENERGY STAR Certification and Green Leasing grant award, multifamily properties must have 20 or more units.


EPA’s ENERGY STAR Portfolio Manager tool helps users measure and track the energy and water use, waste and materials, and greenhouse gas emissions of their buildings, all in a secure online environment. Results can be used to identify under-performing buildings, set investment priorities, verify efficiency improvements, and receive EPA recognition for superior energy performance.

By entering details about the property and consumption data into Portfolio Manager, one can:

  • Assess whole building energy performance.
  • Track changes in energy, water, waste, greenhouse gas emissions, and cost over time.
  • Track green power purchases.
  • Create custom reports.
  • Share data with others.

The steps to share read access to your building’s data with the program staff are available here.  The Sustainable Energy Program staff is available to assist with the process.

ENERGY STAR Portfolio Manager Assistance

The EPA offers a variety of resources to help users navigate the ENERGY STAR Portfolio Manager tool. The ENERGY STAR Help Desk offers an extensive list of searchable FAQs as well as different avenues to contact EPA staff with questions. EPA also offers Portfolio Manager Trainings that include full-length or short training videos, either in pre-recorded or live viewing formats.


Benchmarking is the practice of comparing the measured performance of a device, process, facility, or organization to itself, its peers, or established norms, with the goal of informing and motivating performance improvement. When applied to building energy use, benchmarking serves as a mechanism to measure energy performance of a single building over time, relative to other similar buildings, or to modeled simulations of a reference building built to a specific standard (such as an energy code).

Benchmarking is useful for property owners and facility operators, managers, and designers. It facilitates energy accounting, comparing a facility’s energy use to similar facilities to assess opportunities for improvement, and quantifying/verifying energy savings.

Commercial building energy performance benchmarking is a foundational element of an organization’s energy management strategy because you can’t manage what you don’t measure. Across many commercial building markets, the practice has become standard operating procedure as energy costs and associated environmental and sustainability issues have raised awareness around the importance of energy management. To assist with the connection between benchmarking and energy management, the following topics reference appropriate portions of energy management resource guides.

Green leases (also called aligned leases, high-performance leases, or energy-efficient leases) are rental agreements in which tenants commit to or gain incentives by participating in water/energy conservation, waste reduction and recycling, use of non-hazardous cleaning products, or other sustainable actions.


Green leasing aligns the financial and environmental benefits of landlords and tenants to work together to save money, conserve resources, and ensure the efficient operation of buildings. These contractual arrangements can serve as a powerful mechanism to assist the commercial real estate industry in responding to market pressures and increase energy efficiency of the existing and newly constructed building stock.

Applicants must submit documentation showcasing specific clauses or language that promotes energy efficiency practices.

The lease or related documents must contain at least three of the following:

  • Provision requiring regular scheduled tenant disclosure of utility data to facilitate whole-building energy benchmarking  
  • Building standards and/or tenant improvement guidelines for energy efficiency. For example:
    • “Tenant improvements will conform to LEED C.I. standard or better.” 
    • “Tenants will install ENERGY STAR appliances only.” 
    • This may also cover items like lighting specification or available plug load watts per square foot.
  • Sustainable operations and maintenance rules and regulations. (Language should cover restricted HVAC weekend operating hours, janitorial services provided during daytime hours, tenants not allowed to bring in space heaters).
  • Sub-metering of tenant spaces or separate metering of tenant plug load and equipment. Ideally tenants are billed per actual use rather than on a pro-rata basis.
  • Landlord agrees to incorporate energy management best practices into building operations, such as regular benchmarking, energy audits, or commissioning of building systems.
  • Landlord provides sustainability training to leasing agents and/or building marketing materials cover sustainability and energy efficiency features. (Documentation can include any relevant materials and is not expected to be included in a lease itself.)
  • Landlord designates a sustainability point of contact within the lease or related documents.
  • Lease language specifies that the landlord may sell power generated on-site to tenants at a competitive price.
