ABSTRACTS
International Standards for the indoor environment - Where are we and do they apply WORLDWIDE?
On the international level ISO (International Organization for Standardization, ISO EN 7730), CEN (European Committee for Standardization, prEN15251, EN13779) and ASHRAE (American Society of Heating, Refrigerating and Air Conditioning Engineers) are writing standards related to the indoor environment. This presentation will focus on the development of standards for the indoor thermal environment and indoor air quality. In the future, recommendations for acceptable indoor environments will be specified as classes. This allows for national differences in the requirements and also for designing buildings for different quality levels. This will require a better dialogue between the client (builder, owner) and the designer. It is also being discussed how people can adapt to accept higher indoor temperatures during summer in naturally ventilated (free running) buildings. Several of these standards have been developed mainly by experts from Europe, North America and Japan, thus guaranteeing a worldwide basis.   Are there, however, special considerations related to other parts of the world (lifestyle, outdoor climate, and economy), which are not dealt with in these standards and which will require revision? Critical issues such as adaptation, effect of increased air velocity, humidity, type of indoor pollutant sources etc. are still being discussed, but in general these standards can be used worldwide. It is nevertheless important to take into account people's clothing related to regional traditions and season.

THE EUROPEAN ENERGY PERFORMANCE OF BUILDINGS DIRECTIVE (EPBD)
From the beginning of 2006 all new European buildings (residential, commercial, industrial etc.) must have an energy declaration based on the calculated energy performance of the building, including heating, ventilating, cooling and lighting systems. This energy declaration must refer to the primary energy or CO 2 emissions. The directive also states that the energy performance calculation must take into account the indoor climate, but gives no guidelines. The European Organisation for Standardization (CEN) is now preparing a series of standards to cover the requirements for the indoor environment, energy performance calculations for buildings and systems, ways of expressing energy performance, inspection of heating-cooling-ventilation systems and conversion to primary energy. This paper presents the EPBD and related standardisation. It also gives the status of the on-going implementation of the directive and discusses the issues related to the indoor and outdoor environment.
