Project description: 

The generation of power and energy policies in Mexico is based on fossil fuels; consequently, in the medium term, the country will face a shortage of resources. The energy sector, apart from a few exceptions, is organized at the national level; electricity rates are determined by the government and subsidized from the government budget. The country’s high potential for increasing energy efficiency (EE) and the use of renewable energy (RE) are impeded by unfavorable framework conditions, both in the energy and the building sector. The main reasons for this are a deficit of clear political objectives and strategies, of favorable legal framework conditions and regulations, of support mechanisms and dissemination programs with greater involvement of the private sector, and the lack of awareness, practical experience and training opportunities for stakeholders. Mexico has already taken first steps towards a sustainable housing sector through programs such as the "Hipoteca Verde "and "Ésta es tu casa". Both programs provide additional loans to cover the additional cost of energy efficiency measures in new buildings.

In 2011, CONAVI with support from GIZ, through the financial support of the BMU, developed the technical design of the "Nationally Appropriate Mitigation Actions (NAMAs)" for new housing. With NAMA, the "whole building approach" to assess the energy efficiency of residential buildings was introduced in Mexico for the first time. In December 2012, Mexico presented during the COP 18 the concept paper of NAMA for existing housing.


Service description: 
  • Review and analysis of information and data required, establishing the energy balance of three "status quo" types in order to define the baseline for existing housing, including the development of its methodology;
  • Analysis of energy balances, setting examples for improvement of target values of reference cases;
  • Estimated mitigation potential of the NAMA of existing housing;
  • Cost analysis of the implementation of the NAMA of existing housing; and
  • Review and adaptation of the design concept of the MRV system and the monitoring strategy for the Mexican NAMA of existing housing.

The development of the technical design of the "Nationally Appropriate Mitigation Actions" for Existing Housing aims to improve the energy efficiency of existing housing in the country and thus to reduce their emissions of greenhouse gases. This contributes to meeting Mexico's commitment to face the challenges of climate change, as set out in the General Law on Climate Change. Mexico and its partners develop standards for improvement, based on the "whole building approach" that can be achieved by existing homeowners. This approach allows the parties involved to find the solution with the most efficient cost-benefit ratio. Thus, considering the interaction of all the measures implemented, the reduction of the total energy demand will be incentivized.
