The 2019 California Energy Code became effective on January 1, 2020. [5] It focuses on such areas such as residential photovoltaic systems, thermal envelope standards and non-residential lighting requirements. Homes built under this code are about 53% more energy efficient than those built to comply with the 2016 Energy Code. [6]
To meet Tier 1 or Tier 2, designers, builders, or property owners must increase the number of green building measures and further reduce percentages of water and energy use and waste to landfills in order to meet the threshold levels for each tier (these measures are listed in Section A4.601.4.2 (Tier 1) and Section A4.601.5.2 (Tier 2)).
