    1. ENVIRONMENTAL ASPECTS OF BUILDINGS Some problems and the way forward Adam Pinney CEN Consultant for Construction

    2. Environmental aspects Parameters 1) Dangerous substances. 2) Products in contact with Drinking Water (EAS). 3) Durability and life-cycle costings. 4) Energy performance of buildings.

    3. Dangerous substances the problems

    4. 'Structure' in Member States for Dangerous Substances

    5. Dangerous substances the problems 1) Many regulations are 'passive', i.e. they become 'active' only when necessary. 2) Regulations may not be quantifiable (e.g. what is 'zero content'? "The product shall not contain any dangerous substances", what level quantifies 'dangerous'?). 3) Many regulations assume 'deemed to satisfy' without evaluation. 4) Test methods may not exist or may be impractically expensive. These make implementation in standards difficult.

    6. Dangerous substances Current implementation in standards

    8. Dangerous substances More precise implementation examples 1) " " 2) "Products covered by this standard do not contain dangerous substances." 3) "No part of a ceiling shall contain asbestos." 4) "For the control of dangerous substances for products sold in the European Economic Area (EEA), see Annex ZA; products sold outside the EEA shall conform to any regulatory provisions on dangerous substances applicable in the country of use."

    9. 5) "Ceramic tiles shall not release cadmium. Where verification of cadmium release is necessary*), this shall be in accordance with EN ISO 10545-15:1997 and the resulting value stated. *) This usually applies to contact with food (kitchen tops, etc.)"

    10. 6.4 Formaldehyde release Where formaldehyde-containing material is added to any of the components of the ceiling as a part of the production procedure, the component shall be tested and classified into one of two classes: E1 or E2. This requirement does not apply to components having naturally occurring levels of formaldehyde, which may be classified E1 without the need for testing. Components which have neither formaldehyde containing materials added nor which have naturally formaldehyde levels occurring do not have to be classified and declared in respect of formaldehyde release.

    11. Table3 Formaldehyde Class E1

    12. The CEN way forward CEN 'BOSS' Guidance on solving difficult problems 1) Get someone else to do something clever. 2) Er 3) That's it.

    13. The real way forward 1) Establish 'horizontal' test methods and requirements. 2) Do not over-regulate. 3) Do not move resources. 4) Mainly a second generation problem.
