Greeting

It was with the adoption of the Kyoto Agreement in 1997 that

sustainable development became a long-term goal of global

politics. The effects of the construction sector on the environ-

ment, with a share of about 40% energy consumption and about

50% raw materials, are enormous.

Sustainable development in the construction sector is a res-

ponse to new requirements, not simply with additional building

works or the replacement of existing building works with new

ones. Construction in existing buildings is thus becoming more

important. The importance of building maintenance becomes

clear when one considers the size of the amount invested in

the building, which is around 50% of the capital tied up in it.

Successful planning requires a goal-oriented check that focus-

ses on the relevant criteria and a properly executed decision

process is of crucial importance. There is a broad spectrum of

approaches to solutions that includes construction as well as

operational measures.

Practising experts have realized for quite a long time that they

are confronted by this task on a daily basis. This is why, at the

national level, methods to handle construction on existing

buildings have been in the process of development for seve-

ral years. In view of the great interest of European politics in

harmonized regulations, mandate M/515 of EU/EFTA has given

priority to linking building maintenance to CEN for the re-wor-

king of Eurocodes. The responsible working group CEN/TC250/

WG2 has been commissioned with the task of working up the

principles in the form of CEN/TS (Technical Specifications).

These complement Eurocode EN1990 Basis of Design. The ma-

terial-specificrulesforconstructioninexistingbuildingsareto

follow and be integrated into the appropriate Eurocodes.
