Cal-THRIVES
A California Toolkit for Heat Resilience
Heat is increasingly extreme in California’s Central Valley, where low incomes, poor air quality, old homes, and high utility bills adversely impact many residents. The multi-disciplinary Cal-THRIVES project has developed a cooling toolkit for local and state stakeholders below with the following objectives:
- Increase awareness of heat-related vulnerability
- Identify areas that are vulnerable to extreme heat events
- Remedy the built environment, such as building retrofits & increases to tree canopy
- Enhance home cooling programs
Our research and heat-resilience recommendations incorporate both stakeholder inputs and science:
- Stakeholder Engagement
- Cooling center characterization and improvements
- Neighborhood-scale building modeling
- Outdoor measure modeling
- Overview slides [pdf file]
Cooling Toolkit
One-page and pocket community guides detailing tips for staying cool in the heat are available for download in English and Spanish.

The toolkit offers a collection of fact sheets about passive and active cooling measures, ideal for use with more specialized audiences like DIY-enthusiasts, NGOs and program administrators.

Modeling summaries for building and outdoor measures are available for extreme heat resilience program developers, engineers, and researchers.
Modeling Summary Matrices
For extreme heat resilience program developers, engineers, and researchers, software tools are available to assist with neighborhood-scale building modeling.
CityBES
CityBES is an open tool for neighborhood- to urban-scale building modeling, which can model energy savings for one building or a group of buildings. Both passive and active indoor measures are modeled.

Heat Vulnerability Index (HVI)
A Heat Vulnerability Index (HVI) modeling tool for Fresno is available online.
This toolkit was developed as part of the Cal-THRIVES project funded by the California Strategic Growth Council.
