Since 1995 with the first edition of the GUM by Joint Committee Guide for Metrology, (JCGM) expression of uncertainty in measurement takes a large part in measurement activities.
It contains publications and abstracts of articles related to energy efficient ventilation. Where possible, sufficient detail is supplied in the bibliographic details for users to trace and order the material via their own libraries. Topics include: ventilation strategies, design and retrofit methods, calculation techniques, standards and regulations, measurement methods, indoor air quality and energy implications etc.
Entries are based on articles and reports published in journals, internal publications and research reports, produced both by university departments and by building research institutions throughout the world. AIRBASE has grown and evolved over many years (1979 to present day, over 22000 references and 16000 documents available online). For most of the references, the full document is also available online.
Access to the publications is free of charge.
Since 1995 with the first edition of the GUM by Joint Committee Guide for Metrology, (JCGM) expression of uncertainty in measurement takes a large part in measurement activities.
Because of temperature-based uplift within the building and the impact of wind on the building, airtightness measurements of high buildings are especially challenging.
The PerFluorocarbon Tracer (PFT) method is a low-cost approach commonly used for measuring air exchange in buildings using tracer gases.
For the coming energy-efficient buildings, the guarantee of energy performance becomes a major challenge.
This paper gives an overview of the work undertaken within CEN TC 156 WG 3 dealing with ductwork for ventilation in buildings.
