Awaiting Assessment

LEED v5 Prerequisites

Carbon Assessment

Requires 25-yr model of operational, refrigerant, & embodied carbon emissions.

MRp2 Embodied Carbon

Requires structure, enclosure & hardscape GWP inventories and top 3 source flags.

0

MRc2 Embodied Credit

Estimated points earned for embodied carbon reduction (0-5 points available).

Operational Energy Demands

Calculated Baseline EUI

Energy Use Intensity (EUI): 0 kBtu/ft²/yr (0 kWh/m²/yr)

HVAC Refrigerant Leakage

LEED v5 requires accounting for equipment refrigerants. Provide estimates for primary HVAC heating and cooling systems.

Registered Systems

No refrigeration systems added. Minimum 1 required for Carbon Assessment Prerequisite.

Decarbonization Measures

Adjust variables to simulate energy efficiency improvements, electrification schedules, and grid-decarbonization trends over 25 years.

0%

Reduces base electricity and gas loads across all years.

0 kW

Generates local green energy to offset grid power. Est: 0 kWh/yr.

Never

Eliminates fossil fuel (gas) combustion, transferring heating loads to high-efficiency heat pumps.

0%

Annual compounding reduction in grid emission factor over 25 years.

0%

Offsets grid operational electricity footprint using certified contracts (LEED compliance).

25-Year Emissions Projection Trajectory

0% Net Decarbonization

* Year 0 spike represents the upfront embodied carbon. Operational emissions scale over the subsequent 25 years as the local grid decarbonizes and building systems run.

Commuter Profiles

Define commuter categories for your building and estimate their mode split (modal share) to calculate commuter carbon.

India-Specific Mode Split (%)

Total Mode Share: 100%

Active Commuter Profiles

No commuter profiles added. Minimum 1 required for Carbon Assessment Prerequisite.

Annual Transportation Carbon: 0 t CO2e/yr

25-Year Cumulative Carbon: 0 t CO2e
