The Commission is in the process of updating some of the content on this website in light of the withdrawal of the United Kingdom from the European Union. If the site contains content that does not yet reflect the withdrawal of the United Kingdom, it is unintentional and will be addressed.

Buildings (both domestic and non-domestic) in EU are responsible for approximately 40% of the primary energy use. This makes buildings the largest 'energy-using-sector' in the Union. From the energy point of view, one can reduce consumption: by using building products that are sustainable (e.g. have little embodied energy), by designing and constructing buildings that use as little energy as possible with respect to heating, cooling, ventilation, etc. and by maintaining and operating buildings without wasting energy.

This is defined in EN 13829, § 6.1.2. All exterior surfaces, plus floors, ceiling and walls to neighbouring apartments are taken into account. However, other assumptions are used in some countries to extract indicators that better fit the national requirements of the EP-regulations (see question regarding the measurement of multi-family buildings).

VDI Guideline 6022, one of the most popular Guidelines published by VDI. Since 1998, more than 10.000 copies of VDI Guidebooks have been printed and thousands of people went to the training described in the guidebook. As the result the hygiene standard in air-conditioning systems today is much better than 10 years ago. REHVA´s Swiss member SWKI accepted the VDI 6022 Guideline as SWKI-2003-5, in 2003. The REHVA working group revised and updated the German Guidebook with some new ideas and procedures.

In many studies, prevalence of sick building syndrome symptoms has also been associated with characteristics of HVAC systems. The evidence suggests that better hygiene, commissioning, operation and maintenance of air handling systems may be important for reducing the negative effects of HVAC systems.
