NEW EPBD RELATED EUROPEAN STANDARDS AND THEIR RELATION TO BUILDING AND HVAC SYSTEM SIMULATION

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.

PROPOSAL OF JAPANESE STANDARD OF THE MEASURING METHOD OF AIRFLOW RATES OF BUILDING EQUIPMENTS

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.

Addendum 62n. Single-zone and dedicated outdoor air systems

That addendum 62n modifies the ANSI/ASHRAE Standard 62 "Ventilation for Acceptable Indoor Air Quality, it contains an update to the minimum prescribed ventilation rates and includes ventilation airflow "additivity" for dilution of people-source and building source contaminants.

Ventilation procedures for better indoor air quality

To give some rules to the construction industry, a new standard on the ventilation was issued in Portugal (NP 1037-1:2002). This standard deals with natural ventilation. Some researchs are being carried out to assess impact of the natural ventilation on indoor environment.

THADE Project: guidelines and standards on indoor air quality in dwellings

This paper is the presentation of the authors'work in the THADE project. Their objective has been to review legislation and guidelines on air pollution and air quality in European dwellings and outside Europe too.

Critical appraisal of the setting and implementation of indoor exposure limits in the EU (INDEX) A project funded by the European Commission-DG SANCO

The aim of this 24 months' project is to create a European network in the area of indoor air pollution with the listing of priority substances to be regulated indoors, recommendations, legislation... at world scale.
