INTENT
The intent of this Imperative is to foster the development and use of carbon-free renewable energy resources while avoiding the negative impacts of fossil fuel use, primarily the emissions that contribute to global climate change.
REQUIREMENTS
All projects must supply one hundred and five percent of their project’s energy needs through on-site renewable energy on a net annual basis, without the use of combustion.
All projects (except single-family residential) must sub-meter major energy end uses.
All single-family residential projects must develop a method to understand and troubleshoot energy use.
All projects must account for the total embodied carbon emissions (tCO2e) from construction (including the energy consumed during construction) through the utilization of carbon-sequestering materials and/or through a one-time carbon offset purchase through an ILFI-approved carbon offset provider.
All projects must develop and incorporate a resilience strategy to allow the building to be habitable for one week, or otherwise participate in support for the local community in a disaster, through the use of batteries, storage, etc.
CHANGES FROM LBC 3.1 TO 4.0
Two changes have been made to the requirements of this Imperative to more comprehensively address embodied carbon and resiliency concerns. The embodied carbon offset requirements from Imperative 11, Embodied Carbon Footprint in LBC 3.1 has been incorporated into the requirements of this Imperative with minor modifications. Additional compliance pathways for meeting the resiliency requirements have also been added.
