Blueprint for nZEB tracker: the Climate Action tracker


> The Climate Action Tracker reveals major differences

between the ambition levels of countries when it comes to

reducing greenhouse gas emissions.

> Rates individual climate actions against obligations of the

world‘s countries and shows impact on global warming

> Detailed country sheets available

> Country sheets and information on actual climate impact

allow policy recommendations

ZEBRA Process for Developing the nZEB Tracker

> Pre-conditions for tracking market maturity for nZEB across Europe:

– « working definition » for nZEB

– Criteria for market maturity


© ECOFYS | |

Starting point: Definition of nZEB

> Immense variety across Member States:

– Building standards

– Climate

– calculation methodologies

– building traditions

– Status of « official « nzeb implementation

> Zebra NZEB-Tracker is to monitor the entire nZEB market, including

renovation market.

> Definition must support tracking of new buildings and deep renovation.

– Option 1: Find global definition

– Option 2: Apply national definitions


© ECOFYS | |

Option 1: Global Definition

> Several approaches exist for a global definition, e.g. REHVA or

COHERENO project.

> Advantage:

– Definition featuring one indicator factor like primary energy

supports meaningful comparisons of building energy efficiency

standards across countries

> Disadvantage:

– In reality country approaches differ significantly even if primary

energy is the common indicator; it is unrealistic to re-calculate

with a uniform methodology for a meaningful cross-country

comparison.

Preferred Option 2: National nzeb Definitions

> Decision: Use of national nZEB definitions and defining relative

energy efficiency categories / clusters.

1. Net zero energy buildings / Plus energy buildings

2. nZEB buildings according to national definitions

3. Buildings with an energy performance better than the national

requirements in 2012

4. Buildings constructed/renovated according to national minimum

requirements in 2012

> Allocates buildings relative to the national building code and the

official national nzeb definition

> Starting point: Minimum 2012 energy performance requirements,

allows for monitoring the process towards nZEB in a country.

The nZEB radar: Visualization of building clusters (1)

26/02/2015

> Circles 1-4 represent the four clusters

> the inner circle (1) representing the most efficient building standard

(net zero/plus energy)

> the outer circle (4) the least efficient standard.

> The share of the total circle radius represents the relative share of all

annually newly constructed or deeply renovated buildings respectively.


1.Net zero / Plus energy buildings

2.National nZEBdefinition

3. Better than 2012 national requirement

4. Minimum national requirement2

The nZEB radar: Visualization of progress over time (2)

> In addition, a simple stacked column chart will be used for visualizing

progress throughout a number of years

The nZEB Euro Radar


> EU radar summarizes individual

national results

> It merges the relative shares of each

building category and country “total

number of yearly constructed or

renovated buildings”-

> allows comparing of all included MS

and generation of weighted EU

average.

Tracking the Market Maturity for nZEB


© ECOFYS | |

Theory Based Tracking of Market Maturity

26/02/2015

> Different theories to explain product life-cycle.

> Mainly used for market mapping whereby the positioning of a product/business in

the market is compared to other products/ competitors.

> Not exactly suitable for nZEB.

> Major difference: market share in 2020 is pre-defined by EPBD!

New Approach: Tracking nZEB Market Maturity with

Specific Set of Criteria

26/02/2015

Society

Policy

Industry

nZEB related …

Information• Awareness/ information/ acceptance• Dependency of property value on

energy performance

Realisation• Market penetration• Use of appropriate technologies

Standards• Ambition level and accuracy of

national nZEB definition

Incentives• National policies• Economic boundary conditions

Promotion • Industry involvement

Competitiveness• Availability of nZEB components• Level of expertise of actors


© ECOFYS | |

Question 1 – Relative importance of criteria

(Aggregating criteria)


Which set of criteria is most important for measuringmaturity of the nZEB market?

1) Information2) Realisation3) Standards4) Incentives5) Promotion6) Competitiveness

Question: How to weigh countries?

1) By population size

• Relatively stable

2) By Building stock size (number of buildings / floor area)

• Much weight on populous countries

3) By annual new built floor area

• High rating for growing markets

4) By national GDP

• Much weight on prosperous countries

5) By building sector energy consumption

• Dynamic, automatically highlighting need forprogress (the better the performance, the lessinfluence on overall criterion)

6) Weigh countries equally (1:1)

• Negating disparities

Question 2 – European result - Aggregating country
