The RESNET Carbon Trifecta: HERS Index + CO2 Index + Embodied Carbon
The "trifecta" of RESNET standards concerning operations (HERS Index), the grid (CO2 Index), and embodied carbon together provide the capacity to analyze Carbon Usage Intensity. This session will explore time-of-use, load reduction and carbon sequestration in buildings at both the single-family and multi-family (up to 25 units) scale to show cumulative impact. We’ll also discuss the policy benefits of energy labeling and decarbonization for advancing climate literacy, and the economic, health, and social benefits of implementing RESNET carbon trifecta methods.

Learning Objectives:
- Explain how the RESENT Carbon “Trifecta” allows calculation and analysis of blended metrics like Carbon Use Intensity.
- Describe how such a blended metric facilitates a Whole Lifecycle Analysis at the residential scale and how close are we to being able to do this.
- Take advantage of the critical role that RESNET HERS Raters can play in building resiliency, especially in EJ neighborhoods, through the evolution of dynamic grid electrification to reduce peak load, and carbon sequestration in buildings.
- Assess the cumulative impact of simple materials substitutions at the scale of multifamily residential developments.
