Ordinance 3244-25 - Air conditioner energy efficiency for existing homes.

Ordinance 3244-25, titled Air conditioner energy efficiency for existing homes, is a regulatory action by the City of Sunnyvale, California, to increase energy efficiency in existing residential buildings. The ordinance mandates the installation of heat pump air conditioning systems once a standard air conditioning system reaches its end of life. This initiative is designed to reduce greenhouse gas emissions and align with the goals established in the city's climate action playbook, focusing on the maintenance and protection of the local environment and natural resources. The project is managed by the City of Sunnyvale, with Suzanne Park, the Chief Building Official, serving as the primary point of contact. Under the California Environmental Quality Act, the project has been granted a Notice of Exemption as it involves regulatory actions for environmental protection that impact existing buildings without expanding their use. The administrative activities are centered at 456 W. Olive Ave, Sunnyvale, CA 94086, and the ordinance specifically targets energy efficiency standards for existing building remodels, additions, and alterations.
