The National Model Energy Conservation Code (IECC-Mexico) was developed by the group Quality and Sustainability in Buildings (Calidad y Sustentabilidad en la Edificación, A.C. – CASEDI) with the technical support of the Ministry of Energy (SENER) and the National Commission for the Efficient Use of Energy (CONUEE), and financial assistance from WRI and UK Embassy.
The IECC-Mexico was launched in November 2016, and is based on the International Code Council methodology. It comprises all energy efficiency standards related to buildings, both NOM (mandatory standards) and NMX (voluntary standards), for design, building envelope, thermal insulation, mechanical systems, lighting systems and water heating. IECC- México applies for non-residential buildings (including mix-use buildings) and residential buildings (low-rise, up to three stories), new or existing.
In 2017, the National Housing Commission (Comisión National de Vivienda – CONAVI) updated the building code for the residential sector (Código de Edificación de Vivienda – CEV). The CEV collects and organizes information on constructive technical procedures, zoning land use for housing, efficient urban planning zones and sustainability criteria such as energy performance.
