NOM-007-ENER-2014: Energy efficiency in lighting systems in non-residential buildings

Last updated: 18 July 2019
This standard establishes the minimum energy efficiency levels in terms of Electric Power Density (DPEA) which the lighting systems for general interior and exterior use of new non-residential buildings, extensions and modifications of existing ones must comply. The standard applies to buildings with total lighting connected load equal to 3 kW or more. See the attachment for the minimum efficiency levels.
The uses of buildings covered by this standard are: offices (public and private); schools; hospitals and clinics; hotels and motels; restaurants and cafeterias; commercial establishments (departmental, self-service and specialty stores); warehouses; recreation and culture; service workshops; and passenger centers.
The standard NOM-007-ENER-2014 supersedes the standard NOM-007-ENER-2004. The 2014 version increases the levels of DPEA in all building type use and eliminates the DPEA's levels for open parking lotes.
