Cross-cutting: Establishment of a Mexican NAMA-Office (SEMARNAT)

Mexican – German

NAMA Program

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.

Principal objectives:

Larger penetration of basic efficiency standards (similar level a Hipoteca verde) to all new housing market for low-income families

Scale efficiency standards to more ambitious levels

NAMA program integrated to the National Housing Strategy.

Technical Design

• Change focus: from independent technologies to a whole house approach

• Consider the primary energy demand (electricity, gas and water

consumption)

• Calculation of the total energy consumption for the three different types of

buildings (detached, row housing and vertical) in four bioclimatic zones

Aislada

Detached

Adosada row

housing

Vertical

Sampling cathegories

• Makes use of different prototypes (standards) on energy efficiency

performance:

• Eco-house 1, Eco-house 2 y Eco house Max

Consider differences in performance by:

• Bioclimatic zones in the country

• hot&dry, hot&humid, temperate, semi-cold

• Housing type

• Aislada, adosada y vertical (detached, row housing,

and vertical)

MRV System Overview

Ex – ante

• Simulation models according to the type of house, bioclimatic zone and standards on

energy efficiency (Eco-house 1, Eco-house 2 y Eco house Max)

Ex – post

• Sampling approach for each group of comparable houses

• Annual measurements of gas, electricity and water of NAMA houses

• Annual measurements of gas, electricity an water of reference houses

Calculation:

• Difference between the

results of NAMA houses and

reference houses:

ERy = BEy – PEy

• Tightness

• CO2 levels

• Cobenefits

• The simple (GHG) MRV system will monitor a representative

sample of homes, and estimate within a 90% level of

confidence the emissions performance of these houses by

tracking two + two key parameters

• The comprehensive MRV system will be installed in 3% of

monitored houses and collect data which can be used to: • calibrate GHG models • track non-GHG benefits, • measure “overall house performance” • Can be used to inform policy choices and technology

design.

Scope Challenges Solutions

Institutional

Different initiatives (e.g. Ecocasa,

INFONAVIT) aiming to develop NAMA

packages Adopting a obligatory monitoring protocol

Need for one responsible institution

overseeing the MRV system and operating

the data base. Establish a NAMA coordinator - CONAVI

Lack of coordination of different NAMA

developers Steering committee sessions and MRV

working group

New Government administration and new

Ministry of Urban, Territorial and Agricultural

Development (SEDATU)

Capacity building – enroll. Cooperation

agencies – key role

Scope Challenges Solutions

Financial

Monitoring costs Each NAMA implementor

responsible of monitoring costs.

Market uncertainties – affect housing

developers New financial mechanisms –

capacity building

Behavioural

Lack of access to houses: For meter reading

(or if surveys are undertaken), the houses

have to be accessed or the owner be

interviewed.

Contracts with householders and

provide owner with some

incentives, so that owner wants to

participate in the interviews.

Technology

availability Gas consumption from GLP cilinders - difficult

to measure.

Authorized gas technicians had

been contracted to install the gas

meters accurately.

Emission Reductions

• ERy = BEy – PEy

• Electric: Electricity consumption x Grid emission factor for electricity

generation (consumo electrico por el factor de emision de la red)

• Thermal: Fuel consumption x CO2 emission factor of fossil fuel type

(consumo de combustible por factor de emision por tipo de combustible fosil)

• Water: electricity from pumping (electricidad para bombeo)

What do you do to maintain existing capacities for

the monitoring of NAMA impacts?

• National Housing Commission: creation of steering committee and

host database in existing system (create application programming

interfaces (API) to communicate with other institutions)

• Housing registry: adopting energy savings simulator built on existing

system; staff training for verification of measures.

• Housing developers: capacity building 1) energy savings and emission

reduction simulator and 2) on-site monitoring.

• Housing development banks: financial mechanism linked with minimum

energy performance standards.
