ECA 03: Indoor pollution by NO2 in European countries.

The report summarizes information on indoor pollution by nitrogen dioxide (NO2) In European countries participating in the concerted action "Indoor Air Quality and Its Impact on Man" (COST project 61 3). Major scope of the report IS to give concise information to people involved In research planning, policy making and regulatory activities and to help to identify a European view of the issue. The summary includes a short review of health effects of NO2 and of existing air quality guidelines and standards.

Indoor Air Quality Guidelines and Standards - A State of the Art Review

It is only fairly recently that scientific and public concerns have focused on the probable health risk that the presence of air pollutants can cause in residential or non-industrial buildings. Several reasons have contributed to the deterioration of indoor air quality (IAQ) including some aspects of trends in the construction sector, most important of which are the design of buildings with increased air tightness for the sake of energy conservation but also the use of innovative building materials based on complex synthetic chemical substances.

Radioactivity in building materials önorm s 5200: a standard in Austria to limit natural radioactivity in building materials (revised and definite version)

The Austrian Standard ÖNORM S 5200, prepared in the early nineties after a prestandard phase (Steger F.) and in use in Austria since 1996, provides the criteria to assess the radiation dose of building materials. Gamma radiation of the radionuclides 40K,


In reaction to the European Energy Performance of Buildings Directive (EPBD), existing and newlylanced standard developments by CEN (European Committee for Standardization) were harmonizedand synchronized, resulting in a set of about 50 standards addressing different aspects of the EPBDand the implementation of an overall building energy performance calculation method. A few of themaddress simulation issues:An overview of these is given, focusing on one standard covering system related aspects for buildingswith cooling, humidification or dehumidification.


The measuring method of airflow rates of building equipments is important and is required in manystandards, codes, etc. and the committee of the ventilation planning in the building of SHASE (Societyof Heating, Air-conditioning and Sanitary Engineering), Japan is about to propose the standard for TheMeasuring Method of Airflow Rates of Building Equipments. It is aimed to ensure the quality of indoorenvironment and the performance of HVAC system under the situation that the existing methods are inthe variety but less information for the choosing and its feasibility is available.

Chromatic and luminous characterization of glazing planes: Critical analysis of international standards

In modern architecture glazed units have become a component whose diversified and complex functions shall often satisfy conflicting needs. The glazed element must be capable to modulate and control the radiant and luminous flux incoming into a room improving the quality of vision and living suitability. The task of this study is to highlight the limits of standards in evaluating glazing units, pointing the attention on the luminous and colorimetric parameters and their influence on people satisfaction and comfort.

Listening to the occupants : a web-based indoor environmental quality survey

The web-based IEQ survey is a tool that helps assess how well a building is performing from the viewpoint of its occupants. It is useful to detect and solve problems, and to rate a building performance.The survey conducted in more than 70 buildings has been widely tested and refined.
Three case studies are presented, demonstrating the different possible applications of the survey : evaluation of the effectiveness of a technology, information of the guidelines for a new comfort standard, benchmarking facility performance.

62.1-2004 offers revised ventilation rate procedure

This paper presents the latest edition of the standard 62.1. It combines the 62.2001 version with 17 approved addenda, all of them have been approved by both Ashrae and ANSI. The most significant changes involved the ventilation rate procedure, minimum ventilation rate table and outdoor air treatment requirements.
That document is easy to use for designers, code officials and others users .
That standard is continuously reviewed and revised through addenda to keep up with new research findings and experience from the field.

The Role of Indoor Climate in the European Energy Performance of Buildings Directive (EPBD)

From the beginning of 2006 all new buildings (residential, commercial, industrial etc.) must have an energy declaration based on the calculated energy performance of the building, including HVAC and lighting systems. This energy declaration must refer to the primary energy or CO2 emissions. The directive also states that the energy performance calculation must take into account the indoor climate, but gives no guidelines.
