The ICC voted to improve the 2012 International Energy Conservation Code (IECC) standard by 30% beyond the 2006 IECC, as called for by Architecture 2030. The coalition supporting this move included the US DOE, US Conference of Mayors, the National Association of State Energy Officials and the Energy Efficient Codes Coalition. The 2030 Challenge calls fo the global architecture and building community to subscribe to an ambitious set of standards with the goal of designing buildings that by 2030 will be carbon neutral. For example, the fossil fuel reduction standard for all new buildings and major renovations shall be increased to 70% in 2015, 80% in 2020, 90% in 2025 and 100% (carbon neutral) in 2030.
The 30% improvement will meet the next energy reduction target called for by the 2030 Challenge and by legislation passed in the House of Representatives (H.R. 2454) and in the Senate Bills S.1462 and S.3464.
