Question
Has the energy efficiency and carbon emissions of systems managed by the owner or landlord been assessed in the last five years?
Applicability
All asset classes
Tenant occupied building – some systems managed by the owner/landlord
Answer & Scoring
- Yes – this is a baseline requirement. Complete BOMA BEST Form E1.0b
- Not Applicable – Owner/landlord occupied building OR Tenant occupied building: No systems managed by the owner/landlord
Requirements
For all building components managed by the owner or landlord, provide:
- Building and system description and review. Clearly distinguish between systems that are owned vs managed vs maintained by the owner, landlord or tenant
- Energy utility history (at least 12 months of continuous data, typically the previous 24-36 months of data) for each energy source
- Greenhouse Gas inventory or Carbon emission history (at least 12 months of continuous data, typically the previous 24-36 months of data) for each carbon source
- Low- and no-cost energy conservation and/or carbon reduction measures, with high level costing, simple payback and anticipated savings. If no savings measures are identified, state why
The assessment methodology should at a minimum align with an ASHRAE Level I Audit. While the ASHRAE Level I Audit does not cover carbon, it can be used as a general guideline for the carbon assessment component.
The assessment provided is not required to be completed by a professional engineer.
Refer to ENERGY STAR for carbon emission calculations and creating a GHG inventory. If other carbon emission factors are used, explain reasoning and factors applied
For newly constructed high performance and net-zero carbon buildings, an Energy and Carbon Assessment Report is still required. Should there be no low- and no-cost energy conservation and/or carbon reduction measures identified, provide justification beyond the systems being new. Note that while a newly constructed building may be designed to be high performance or net-zero carbon, it does not necessarily indicate that it performs as such or that no further improvements can be made.
If the owner or landlord only manages for example the exterior parking lighting or common-area energy at the building, provide the energy and carbon data for these systems, as well as an assessment of the efficiency of the systems. If the systems were recently upgraded and no energy conservation or carbon reduction is currently feasible, state that too.
For all systems managed by the tenant, the applicant (representing the owner or landlord) is expected to outline those as well, though no energy or carbon assessment is required for these systems.
Documentation
- Limited Scope Energy and Carbon Assessment Report
OR
OR
- Documentation demonstrating that no systems are under the building owner/landlord’s control (e.g. lease agreement)
Suggested Lead
In-house: Facility Maintenance, Potential in-house energy/sustainable operations staff
Third-party: Energy/engineering consultants
Value
- Understand a building’s environmental impact through energy use and carbon emissions data analysis
- Perform an entry-level energy and carbon assessment to define a building’s baseline energy consumption and carbon footprint through utility analysis
- Identify ways to reduce energy use and carbon emissions through low-cost energy conservation measures (ECMs) and carbon conservation measures (CCMs)
- This assessment can be performed in-house using the BOMA BEST Template provided in the How-to Manual or by a qualified third-party
- The question is applicable to spaces both inside and outside of the building.
- Engage a qualified third-party professional to provide more detailed recommendations to improve building performance, save on operational costs, and reduce a building’s overall environmental impacts

Description
The most effective energy reduction strategies will focus efforts on the end uses with the highest consumption. Building operations and management teams should determine the largest end uses and consider opportunities for sub-metering significant loads, such as tenant process loads or mechanical equipment.
