Question #

E10.2 — On-site Combustion

Question

Has the building transitioned off all forms of on-site combustion?

Applicability

Applicable to all buildings (systems or equipment in the owner or landlord’s control)

Answer

Select all that apply:

    • Yes — equipment has transitioned
    • No — equipment has not transitioned
    • N/A – on-site combustion was never used

Description

Mechanical equipment and HVAC system efficiency offer the most impactful opportunity for active energy and carbon reduction across all fuel types. To achieve decarbonization goals, building management should plan to replace end-of-life, inefficient or high carbon equipment with high efficiency, low carbon options as part of asset renewals.

Heat recovery should be considered for all systems as a strategy for reducing consumption.

Electrification works toward elimination of carbon emissions related to onsite combustion, and improves opportunities for reduced electricity-related emissions through energy supply from clean grids (either now or in the future) and the use of renewable energy.

Requirements

    1. Provide a brief summary attesting that there is no onsite combustion equipment used at the property as part of regular building operations

Documentation

    • Evidence that there is no equipment in use as part of regular building operations that relies on-site combustible energy sources

Other Notes

Typical on-site combustion equipment deliver space and domestic water heating and includes gas-fired boilers, gas-fired rooftop units, makeup air units.

The following combustion equipment is excluded from this Question:

    • Tenant-specific equipment used in restaurants (cooking etc.)
    • Emergency generators or back-up power equipment using diesel or other fuels
    • District heating systems serving the building

Points will be awarded regardless of when the transition occurred. The building team only need to demonstrate that on-site combustion was part of the original building and has since transitioned.
