Existing Building Actions
Achieving zero emissions from the existing building stock will require accelerating the rate and depth of energy upgrades by leveraging building intervention points.
For full building sector decarbonization, every existing building will need to undergo energy upgrades involving a combination of: improvements in the energy efficiency of building operations, a shift to electric or district heating systems powered by carbon-free renewable energy sources, and the generation and/or procurement of carbon-free renewable energy.
Building intervention points occur at: point-of-sale; major renovations; building systems, materials and equipment replacements; capital improvement cycles; zoning or use changes; and life-safety and resiliency upgrades (e.g. seismic, flooding, fire prevention, power disruption).
By aligning energy upgrades with market-driven intervention points the cost and disruption to building owners and users can be significantly reduced. Intervention point-aligned energy upgrades also catalyze expanded markets for building renovations and carbon-free renewable energy generation that stimulate a sustained increase in local jobs, market growth, and tax revenue.
