A questionnaire presented to designers demonstrates the difficulty to explain the specific status, thestratification and the correlation of parameters, features, concepts, principles and requirements.
S. De Bruycker
In schools the temperature of the indoor air is one of the most important factors in terms of the indoorclimate.
Birgitta Nordquist
The current rate of consumption across Europe is leading to environmental problems. We need toreduce our impact to nature - our ecological footprint - by two thirds to achieve a sustainable andglobally equitable level.
W. Zeiler, J. Van Deursen
The paper presents the results and analysis of the energy consumption of a newly designed office building in relation to quality of the indoor environment.
J. Ferdyn-Grygierek, A. Baranowski
The dependence of the ventilation on the indoor particulate pollution is highlighted by numerousstudies.

The legal background for the assessment of the energy performance of buildings and energycertificates in Germany will be changed in October 2009.
Simon Wössner, Jan de Boer and Hans Erhorn
International building legislation is setting stronger and stronger requirements for the energy performance of buildings.

Due to the increase in CO2 emissions and the resulting climate change more and more efforts aremade to reduce energy consumption.
M. Krus, D. Rösler, A. Holm
It is well known that appropriate ventilation represents one of the prerequisites for achieving goodindoor comfort, and we try to ensure a continuous and sufficient intake of fresh air into a building.
M. Tomsic
For quite a long time energy conservation and energy efficiency were concentrated on a singlebuilding approach.
Heike Erhorn-Kluttig, Hans Erhorn
Ventilation is essential for the health and comfort of building occupants. It is particularly required todilute and/or remove pollutants emitted by occupants' metabolism and activities.
F. Richieri, T. Salem, P. Michel
On the way to the solution of our energy-problems, the conditioning of buildings is the most importantsector.
Gerd Hauser
The paper provides the results of monitoring on the specifics of indoor air quality in Latvian dwellingbuildings.
