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 and risks to human health.
REQUIREMENTS
All projects must supply 105% of their project’s energy needs through on-site renewable energy on a net annual basis, without the use of combustion.
No combustion is allowed for systems in project scope.
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 set a goal to achieve below the ILFI-approved embodied carbon threshold for the upfront embodied carbon of the project (lifecycle stages A1–A5). See Embodied Carbon Threshold Clarifications for more details.
All projects must disclose and offset 100% of the embodied carbon emissions (tCO2e) associated with life cycle stages A1-A5 of primary materials, exterior materials, and interior materials through on-site carbon-sequestering materials and/or by 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.
