Lead Performer: Vistar Energy – Rocklin, California
DOE Total Funding: $149,921
Project Term: July 1, 2018 – July 1, 2019
Funding Type: Small Business Innovation Research (SBIR) Phase I Release 2
Related Projects: EnergyPlus, OpenStudio, ResStock
Project Objective
XeroHome is a web-based multi-tier energy modeling framework for homeowner-driven single-family residential energy modeling applications. The framework is seeded with public data from sources such as property assessor databases, building permits data, and GIS based datasets and provides additional levels of analytical detail and certainty, as a homeowner enters more information such as monthly utility data or HVAC or water-heating equipment specifications. Unlocking the final level of detail requires an in-person audit, serving as a gateway to ratings such as Home Energy Score and HERS/ERI. The service is being designed to serve a customer engagement function for utilities.
Via this project, the XeroHome team will develop and deploy a phase 1 workflow and pilot it with an interested utility partner such as SMUD (Sacramento Municipal Utility District) or SCE (Southern California Edison).
Project Impact
The project targets a large market segment, existing homes, and lowers the barrier of entry for homeowners into the home energy retrofit market. Multiple utilities and program implementers are engaged with the project.
