The « Grenelle de l’environnement » momentum

The French «Grenelle de l’Environnement» Environment Policy, developed in October 2007, created a longterm policy plan for tackling environmental issues and promoting sustainable development.

The « Grenelle de l’Environnement» established the use of renewable energy and green building construction as a priority for France.

The Grenelle ObjectivesTo make all new buildings consume less than 50 kWk/m2/year by 2012 and become energy neutral or positive by 2020. 38% reduction in energy of existing buildings by 202023% of renewable energies by 2020

One vision

Inspiring confidence, sharing knowledge…

The CSTB group supports the innovation in theconstruction sector. In cooperation with its partners and clients, it develops and shares scientific and technical knowledge to make buildings, neigborhoods and communities more sustainable.


3 dimensions

The CSTB group is working on the whole innovation cycle

Its studies address all scales of the construction: from products to sustainable buildings, neighborhoods and cities and all steps of their life cycles , from craddle to grave

The CSTB group tackles all the challenges of thesustainable construction: environment, safety, health, social issues and economic performances

HQE® The French SB Assessment System

HQE is a global approach to improve the environmental quality of the built environment. The NF tertiary buidlings HQE® approach is a certification run by

a subsidiary of the CSTB Group.

The HQE® certification is applicable to all types of new and existing buildings in the residential, tertiary and industrial sectors, as well as roads and highways.

Multi certification, why?


A global picture.Confusion for the market?

CSTB | MAI | Helsinki | Bruno Mesureur | November,13, 2009

Various assessment systems co exist all over the world. But without core principles and comparable rating systems they may be confusing for the construction stakeholders.

There is an enormous and growingappetite for rating methodologies thatcan be used to demonstrate theenvironmental performance of ouractivities.

From personal carbon foot-printingmethodologies to sustainabilityassessments of entire cities andstandards, there is a drive to developmore and more rating methods.

The SB Alliance model allows thesecomparisons by providing a commonplatform for all buildings and constructionstakeholders for addressingsustainability issues of globalsignificance, especially climate change.

SB Alliance

SB Alliance was set up a year ago to define acommon core set of indicators to be shared by thedifferent participating organizations on a voluntarybasis.

This core set is composed of six indicators (GhG,energy, water, Waste, Air Quality, and FinancialPerformance) defined by BRE, CSTB, DGNB, FCAV,VTT and NIST.

It was presented in November during the Batimatexpo in Paris. These organizations have decided toseek UNEP-SBCI’s endorsement

Common metrics for key issues

A proposal for The SustainableBuilding Alliance

Core set of indicators


A core set of indicators, why?

To enable the assessment of main environmental impactsTo develop a common international vocabulary for building environmental assessmentTo facilitate communication between stakeholders To support the development of future assessment schemesTo facilitate inter building and inter countries comparisons

PAGE 23


Key challengesto get the core set of indicators

1. Select first candidates among a large number of potential indicators

2. Define a methodology to assess them

3. Define a way to report on the indicators

4. Define subsidiarity between international and national approaches

PAGE 24


Select first candidates amonga large number of potential indicators

1st step : bottom up approach> Analyze all potential indicators coming from

> Existing approaches> Standards under development

> Get a long list of potential indicators

2nd Step: Top down approach> A vote among SB Alliance members enabled to select first

priority indicators

A pragmatic life cycle approach

The goal is to take into account the whole life cycle But Assessment methods have different levels of maturity> Some elements can be assessed with well known methods

> e.g. Methods used for Energy performance regulations

> Some elements can be assessed with recently developed methods> e.g: Cradle to gate Environment Product Declarations

> Some elements can be assessed with methods which are not available in all countries

> e.g. Cradle to grave Environment Product Declarations


Main sources of data



Elements to be consideredin the 2009 version

PAGE 31


Apply a 20/80 rule

Mandatory> Roof> Load bearing structure> Exterior and basement walls

including windows > Internal Walls > Floor Slabs > Foundation> Floor Finishes/Coverings

Optional> decorative wall finishes/coatings> Doors> Heating/Cooling/lighting

Equipment and any power generating equipment (e.g. wind turbines/PV/solar heating

> Internal Transport (Elevators, Escalators )

> Water and Sewerage systems> Electrical distribution systems

To enable a progressive development only some buildings components or services shall be assessed in 2009 version

PAGE 32


Units for reporting data

Green House Gas emission> CO2 eq (kg)

Energy> Primary energy (kWh)

Water> m3

Wastes> 4 type of wastes differentiated

> Hazardous (Tons)> Non Hazardous (Tons)> Inert (Tons)> Nuclear (kg)

Data are reported for the different stagesPAGE 33


Indoor environment indicator

Thermal comfort> % of occupied period where temperature exceeds a given value

> E.g.: 2% of time temperature above 26°C

Indoor air quality> CO2 in ppm> Formaldehyde in μg/m3

The indicators could be assessed at two stages:> before use> in use

Results presentation

We are now working on the layout

PAGE 36


Subsidiarity between SBAand national approaches

Assessment procedure> Allow the use of national procedures and processes (e.g. energy

calculation procedures etc.) > Provides default scenarios which can be use when no national

data is available

PAGE 37


Presentation of resultsSBA international approach> Define a common detailed

reporting format

National approaches> Define benchmarks and layout


Where are we today

A working group of SB Alliance has produced > A selection of 6 indicators> A methodology to assess them> A method to report on the indicators> A proposal for links between SBA indicators and

assessment schemes

The next steps are> To discuss this proposal with all SB Alliance members> To make a decision> To implement these indicators in assessment schemes
