EDGE is flexible and can be used for almost any building type. If you do not see your building type listed, please contact IFC at firstname.lastname@example.org for guidance.
How does EDGE define a building?
In EDGE, a single building is a physically separate structure. If two buildings are connected by a conditioned space, then they can be considered as a single building.
Is there a building size requirement for pursuing EDGE certification?
Buildings must have a minimum of 200 square meters in gross floor area, excluding parking, to pursue EDGE certification. Note that this requirement does not apply to single family homes.
If your building has less than 200 square meters of gross floor area and you would like to pursue EDGE certification, please email IFC at email@example.com and ask for special permission.
Can existing buildings pursue EDGE certification?
Yes, existing buildings and major renovations can pursue EDGE certification.
As is the case with the certification of new buildings with EDGE, the assessment of existing buildings and major renovations attests to the building’s features, not its performance. EDGE serves as an asset rating instrument that defines whether the building has met the EDGE Standard (at least 20% predicted savings in energy use, water use, and embodied energy in materials compared to a base case building).
Additionally, note that the EDGE Standard remains the same for all buildings, regardless of the stage of their life cycle, and the same base case conditions apply. The only difference is that materials in buildings that are more than five years old will be considered as embodied-energy neutral, to be indicated as “re-use of existing materials” within the EDGE App.
Can buildings under construction or that have been recently completed pursue EDGE certification?
Yes, recently completed projects or projects under construction may pursue EDGE certification as long as they are able to meet the requirements and provide the necessary supporting documentation.
Can EDGE be used for core and shell projects?
Yes, core and shell projects may pursue EDGE certification. According to the guidance in the User Guides, for projects with core and shell condition, the energy, water, and materials measures that will impact tenants can be claimed only if there is a “tenant fit out guide” included in the lease agreement and signed by the tenants and owner. The tenant fit out guide must clearly define the requirements to be fulfilled by tenants for each measure and must be included in the EDGE submission.
Can a commercial interiors renovation project within a building apply for EDGE?
Yes, commercial interiors projects may pursue EDGE. EDGE is not a whole building rating system and individual spaces within a larger building may pursue EDGE. You may need to collect information from the building owner for building elements and/or systems already installed.
Can EDGE be used for Mixed-Use buildings?
Yes, Mixed-Use buildings may pursue EDGE certification.
Can a Mixed-Use building be certified in one EDGE subproject?
For EDGE Version 2 projects, if a building has more than one use and the secondary use occupies less than 10% of the gross floor area up to a maximum of 1,000 square meters, the entire building can be certified under the primary use of the building in one EDGE subproject. Alternatively, if the area of the secondary use is more than 10% of the gross floor area or more than 1,000 square meters, then that portion must be certified separately in a second EDGE subproject.
For example, if a 10,000 square meter residential building has a retail portion of 1,200 square meters located on the ground floor, the building areas must be certified separately under the Homes and Retail typologies. This building is still considered one building for certification pricing purposes.
EDGE Version 3 projects should be certified in a single subproject under the Mixed-Use building type. Modeling a single Mixed-Use subproject will save time for the project team and Auditor. The building will receive a single EDGE certificate.
Alternatively, a Mixed-Use building can choose to model separate subprojects if the area of the secondary use is at least 200 square meters. In this case, each subproject will receive an EDGE certificate and the overall building will NOT receive an EDGE certificate. Please note that in the future, GBCI may levy an add-on fee for projects that choose this more complex modeling scenario.
How many subprojects should be created for multifamily residential projects?
Under EDGE Version 2, a separate EDGE subproject may be created in the EDGE App for each unique type of dwelling unit. For example, a different subproject must be created for a one-bedroom, a two-bedroom, and a three-bedroom unit. The 10% rule governs which residential units can be grouped together and modeled as a single unit type in EDGE.
Alternatively, under EDGE Version 3, all units can also be modeled under a single subproject. In this case, the certificate shows a range of savings across all of the unit types.
Can the EDGE App be used for naturally ventilated projects?
Yes, the EDGE App can be used for naturally ventilated projects. In such cases, the EDGE App assumes that air conditioning or heating will eventually be installed for human comfort. EDGE demonstrates this future required energy for comfort as “virtual” energy, articulating it separately for ease of understanding. While the base case utility costs in the results do not reflect the virtual energy, EDGE determines whether a building is projected to achieve 20% energy efficiency by subtracting the improved case with virtual energy from the base case with virtual energy.
