The document summarizes a supported NAMA for energy efficient new housing in Mexico. It discusses establishing basic efficiency standards for new housing to reduce energy consumption and costs. The technical design proposes target maximum energy demand levels per square meter rather than technology standards for flexibility. Financing would provide subsidies for homeowners. Emission reductions would be monitored through energy consumption sampling and reported using a simple MRV system.

2011 – 2015, German contribution: 7 Mio. Euro
Objective: Mexican NAMAs for residential buildings (new and existing),
SMEs and road freight transport are prepared for large scale
implementation and international co-financing, are partially implemented
and a coordinating Mexican NAMA-Office is established.

5. Two core objectives of the NAMA
1. Extend penetration of basic efficiency standards (similar levels
to Hipoteca Verde) to the entire new housing market in Mexico
2. Upgrade efficiency standards to more ambitious levels
Introduction
Rational for and aim of the housing NAMA
Existing measures succesful but insufficient funds to cover entire new housing
market
Co-benefits: reduced energy costs for low-income households, reduced energy
subsidy costs, better living conditions, create capacities beyond original market
Overall Mexican strategy for long-term transformation of the housing sector
Strong and active promoter in Mexican government
Window of opportunity before elections

8. Technical design
Target values for maximum energy demand
The idea:
Move from technology focus to results based approach
Maximum primary energy demand per square metre and year
Requirements cover all standard energy consumption (heating/cooling, cooking,
typical electrical appliances, hot water)
Advantages of target values for maximum energy demand:
− Incentive to reduce total energy consumption
− More flexibility: Developer/architects and owner can decide which measures are
the most adequate for reaching the requirements based on costs, region/climate,
availability of technology, personal preferences, ...
− Requirements can be easily updated / tightened
− Different requirements can be established in parallel with different support
levels

10. Technical Design
Indirect mitigation measures
1. Institutional set-up and
NAMA administration
Designing NAMA fund, incl. legal agreements
NAMA Program Office Unit
2. Building Codes and
permitting procedures
TechnicalAssistance to local governments and organizations at
state and municipal level
3. Capacity building
Training for energy advisers, planners, construction workers, local
authorities and stakeholders
Support of regional manufacturers
4. Pilot projects and
software adaptation
Adaptation/implementation of PHPP calculation and design tool
Design and construction of pilot projects
5. Marketing and
advertisement
Website, mass media campaign, marketing material

15. MRV System
Energy consumption differs from design due to usage patterns (number of
habitants, usage of heating/cooling equipment, ...)
MRV System will be based on energy consumption for sample houses and
regions
Relatively simple monitoring system:
− Step 1: Identification of sample houses (building types, regions, energy design
standards)
− Step 2: Collection of annual electricty, gas and water consumption
− Step 3: Calculation of emission reductions in sample houses
− Step 4: Upscaling of reduction to national level
Reporting and verification procedures not yet defined
