There are no mandatory forms of energy performance certification in Mexico. However, the NMX contemplates the issuance of a certificate for buildings that comply with its technical specifications.

A party has the option to request a verification unit (in terms prescribed by the Federal Law of Metrology and Standardization) to verify the building’s level of compliance with the standards. The verification unit performs the evaluation in accordance with the requirements and criteria stated by the NMX.

With the aim of further promoting energy efficiency and renewable energy, the Energy Transition Law was developed. This law also regulates the use of renewable energy sources and establishes a national strategy to apply this type of regulation to each Mexican state. In addition, it indicates the instruments that can be used to finance the energy transition (prior to the publication of this law, this regulation was mandated through the Law for the Use of Renewable Energy and Financing of Energy Transition).

However, the Energy Transition Law does not require a specific mandatory process with which buildings or any other type of dwelling must comply, even when it (i) promotes and structures procedures to regulate energy transition and renewable energy and (ii) includes a program called “Recognition for Excellence in Energy Efficiency.” This program is a voluntary certification and recognition process to identify and promote products, equipment and buildings designed and equipped to promote the sustainable use of energy through a voluntary labeling scheme for products and buildings to identify the highest standards of energy efficiency in Mexico. Hence, the Energy Transition Law is more of a matter of promoting and planning improvements in energy performance rather than being forcefully applicable.
