In 2017, the National Commission for the Efficient Use of Energy (CONUEE), the National Institute of Ecology and Climate Change (INECC) and the German International Cooperation Agency (GIZ) developed the pilot project: Excelencia en Eficiencia Energética en Edificios (E4).
The Energy Transition Law (LTE) established the recognition of excellence in energy efficiency as a voluntary process of certification and recognition to identify and promote products, equipment and buildings to make a sustainable and efficient use of energy.
The main objective of this initiative is to evaluate the energy efficiency performance in private buildings and bank branches and to recognize all those through a label, which will serve as a catalyst in the real estate market, to reduce operating costs and carbon footprint.
In other words, the E4 Programme of the voluntary labelling of products and buildings that comply with the highest standards of energy efficiency.
Based on the Energy Star methodology, INECC and CONUEE, with the support of GIZ, developed the algorithms to qualify the energy performance of private buildings for office use, which use an energy comparison technique for properties of the same type in similar climatic conditions and assigned a rating of 0 to 100 points. Buildings graded with 90-100 points receive the excellence label.
In March 2018, CONUEE awarded the first E4 buildings located in the cities of Mexico, Puebla, Morelia and Tijuana, and correspond to the real estate companies Cushman Wakefield, JLL and Colliers, as well as the banking groups HSBC and Banorte Financial Group.
