Mexico has no regulations requiring a percentage of energy consumption to come from renewable resources in buildings. However, the NMX requires every sustainable building to satisfy at least 10% of its total building energy demand with renewable sources, whether it is generated inside or outside the building.

Even though there are currently no regulations that mandate a percentage of energy to come from renewable resources, there are several other Mexican Official Standards that apply nationally and establish requirements and guidelines for efficient energy use for various appliances and buildings. These include energy efficiency for lamps of general use, energy efficiency for residential buildings and energy efficiency for domestic electric refrigerators and coolers.

According to the energy reform implementation process, the Energy Transition Law, which the legislative chambers recently approved, aims to abrogate the Law for the Use of Renewable Energy and the Financing for Energy Transition and the Law for the Sustainable Use of Energy. This new law, which was published in the Official Journal of the Federation on 24 December 2015, establishes a national strategy for finding and implementing different approaches to an improved use of clean energy, sustainable use of energy and energy transition. Among its mandatory targets, this new law sets the following percentages for clean energy in the power generation national portfolio: 25% in 2018 and 35% in 2024 requiring energy from clean sources.

There are currently several NMX projects regarding energy efficiency that are waiting to be reviewed and are expected to come out in the next few years.
