Notas del editor
- I am Chris Hamans from ESC, European Sustainability Consulting.This is presentation nr. 2 on the CEN TC350 standards and informs on the background and development of the European standards of CEN TC350 - a suit of standards for assessessing the sustainability of construction products and buildings.
- 2Who made the standards?
- 3There are rules for making European standards.CEN, the European Standardisation organisation, provides the platform for organising the European stakeholder involvement in making European standards.
- 4 In CEN the national standardisation bodies of all EU countries are represented.
- The CEN TC350 standards are based on a European mandate M350 given to CEN by DG Entr. , the Directorate General for EntreprisesMany European countries were, and still are, involved in producing the standards of CEN TC350.The National Standardisation bodies organise the stakeholder involvement for preparing contributions to the standards content. Customers and users are involved: competent representatives from consumer organisations, NGO’s, industry, inspection and surveillance bodies, sience and research, etc. They specify the national contributions and give a national vote in the CEN voting procedures.
- 6The National Standardisation Bodies only have the voting right in the CEN technical Committee. Also for the CEN TC350 standards they have given their vote to the TC documents. 1 Vote per national Standardisation body, but behind that vote there is the national position based on a broad range of stakeholders.Most of the European stakeholders have their vote in the national Standardisation Body. The real writing of the standard’s draft is done in the working groups of CEN TC350 with input of all experts representing their National Standardisation Body or the liaisoned stakeholder group.
- 7Without a voting right directly in the European standardisation work, the stakeholders also have the possibility to balance and adjust their national input to a common European interest. All experts of the stakeholders contribute directly to the European content of the documents. Writing the CEN standards therefore is both a national and European contribution. But it always requires the approval by majority of the national standardisation bodies.
- 8For the CEN TC350 environmental standards for instance, with this procedure, out of many possible environmental indicators, a European agreement could be achieved on 22 environmental indicators.One should realise that there are other specific environmental indicators that might be used in specific assessment programs, but not included here in this suit of standards. Either because they were lacking a Europe wide accepted scientific background or they could not find support in most of the countries.In this sense Ecotoxicity and Landuse for example are two indicators that could not yet find a Europe wide acceptence for being included in this suit of European standards.
- For instance: Inclusion of indicators in European Standards requires Europe wide acceptance of the indicator, of the methodology and of the calculations behind it. On the indicator EcoToxicity the TC350 stakeholder experts had to conclude that scientists still discuss what methodology is correct and that procedures within these methodologies are applied differently. Based on this situation the TC350 stakeholders could not accept the environmental indicator EcoToxicity.As soon as there is more agreement and wide support for one methodology for quantifying Ecotoxicity, TC350 will be pleased to include this indicator in the revision of the standards.
- For the indicator Landuse, TC350 also concluded that there is not a robust and accepted methodology in Europe available for quantifying landuse. The indicator could not find the European support for inclusion in the standards now.
- What 22 environmental characteristics then could be included in the standards EN15804 and in EN15978?
- 22 environmental indicators were approved. They can be grouped into 4 sections:7 indicators on direct environmental impacts8 indicators on environmental aspects3 aspect indicators describing waste4 aspects indicators describing resources that leave the process or the object of assessment
- In detail you see here the 7 harmonised environmental impacts: dealing with emissions and with use of resources expressed in environmental impact characteristics.
- 8 Parameters are describing the use of resources:They allow the quantification of aspects on the input of resources like different carriers of energy, primary energy and renewable energy.But also parameters to quantify the use of secondary materials, secondary fuels and the use of fresh water.
- Then there are 3 aspects describing the waste that is generated
- And although the standard does not VALUE the indicators that characterise the environmental performance,the standard allows quantifying 4 environmental aspects that result in a positive contribution to the environment.These are the products or fuels that have reached the end-of-waste stageand which are subsituting resources in other product life cycles: - like components for re-use, -materials for recycling, -materials for energy recovery and - exported energy. Together with the use of resources at the input side of a process this information on the output flow of resources and energy, is very useful information for assessing resource efficiency.
- Quantified performance on these 22 parameters, 22 indicators, is the bottom-up flow of information: it is possible to quantify the environmental performance on each information module for a construction product and service. This information on 22 indicators per module allows using it in the environmental building assessment. (more information on the use of information modules you will find in the video on Modules and Scenarios)
- But there is more than anenvironmental score in sustainability. What else is standardised?Well, In the green column – the group of environmental standards – there are the supporting standard EN15942 on the B2B – Business to Business – communication format and there is the technical report TR 15941 on the use of generic data
- Although not finalised at this point in time there are a number of social aspects that are in the middle of the standardisation process.
- in this second pillar of sustainability the work on the methodology standard EN16309 for the assessment of the social performance of buildings is still in progress.
- The methodology standard has to specify the assessment rules for the aspects defined in the framework standard on societal aspects like:Accessability of buildingsAdaptability of buildingsHealth and comfortImpact on the neighbourhoodMaintenanceSafety and SecurityFor these 6 aspects the stakeholders in the standardisation process are searching consensus on the necessary indicators that can describe those societal aspects.2 more aspects, the sourcing of materials and stakeholder involvement, are identified as being difficult to standardise at this point, but we will see.These societal aspects do relate more to the building performance than to a product performance.
- In the economic performance assessment of sustainability, all under the framework standard EN15643-part 4There are two economic aspects: costs and financial value
- You noticed: we jump into the 3rd pillar of sustainability.
- The methodology standard is in development and in the year 2014 the Working group shall deliver the rules for quantifying the life cycle costs for a building and,A suitable and fair set of rules for defining the financial aspects And all of them shall count on a Europe wide agreement.
- This completes the overview of characteristics defined in the sustainability standards.
- All environmental standards are available now. An environmental buildings assessment can be made now based on European standardised rules.
- The standard EN15804 invites for calculating the environmental product performance. The results are expressed and communicated in an EPD, an Environtal Product Declaration
- And the EPD data are made to be used in a building assessment. The standard EN15978 defines the rules for the building assessment
- I am Chris Hamans and welcome your response.
