Carbon Avoided: Retrofit Estimator (CARE) Tool
The CARE Tool (formerly the 2Build or not 2Build Calculator) is used for calculating and comparing the embodied, operating and avoided carbon impacts and benefits of reusing and upgrading existing buildings or replacing them with new construction.
The CARE Tool is now a project of Architecture 2030. Thank you ZNCC members for your support! To learn more about CARE, including how to contribute, click below to be directed to the official webpage.
