LoginWe conducted observations of wind velocity profiles above a high-density area in Tokyo, Japan, using a Doppler LIDAR system.
Bibliographic database Airbase
AIRBASE is the Bibliographic Database of the AIVC. 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.
The zero pressure compensation method has proven to be the best method to measure air flow rates accurately although it also has be shown that the accuracy depends on the type of air terminal device and how and where the pressure to be compensated
In 2014 the first multi storey residential building planned and constructed to meet the Passivhaus Institute (Darmstadt) criteria was put in operation in Ljubljana, the capital of Slovenia.
A new low pressure ‘quasi-steady’ pulse technique for determining the airtightness of buildings has been developed further and compared with the standard blower-door technique for field-testing a range of typical UK homes.
Constructions joints occur everywhere where several construction materials meet. That’s many meters that need to be taken care off, respecting the function that the materials or the joint need to fulfill.
The paper presents airtightness measurements results of the multi-family building.
The Net Zero Energy Residential Test Facility (NZERTF) was constructed at the National Institute of Standards and Technology (NIST) to support the development and adoption of cost-effective net zero energy designs and technologies.
The paper at hand collects research findings on the impact of air flow on the thermal performance of pitched roof assemblies. Air flows in these components are typically a mixture of: 1) in/exfiltration, 2) natural convection and 3) wind-washing.
Mastering building airtightness is essential to meet the requirements of current and future building codes, not only for saving energy but also for ensuring moisture safety.
Interior wooden surfaces have the capacity to buffer the maxima and minima of relative humidity (RH) indoors.
Against the background of increased global demands for energy efficiency, property owners should raise the standards of ductwork systems for ventilation, heating and air conditioning.
This presentation will explain what exactly calibration should mean.
The objective of this paper is to assess the impact of the envelope airtightness on airflow patterns for single detached dwellings depending on the ventilation system.
ATTMA, the Air Tightness Testing & Measurement Association has introduced mandatory lodgement for all members, representing over 140 companies and over 350 test engineers across the UK.
In timber frame construction in Europe air barrier systems are typically realised at the interior side of the building envelope.
This paper presents airtightness data measured for about 752 units of high-rise reinforced concrete buildings (apartment buildings) that have been recently constructed within five years in Korea.
Over three million subsidised dwellings were built in Spain between 1940 and 1980. Most of these buildings are now obsolete and fail to comply with thermal comfort and ventilation standards.
Since 2000, the French EP-calculations have been considering thermal losses due to building envelope airtightness.
Ventilation of buildings and homes is a key issue both from comfort and energy aspects. However to determine the average ventilation air flow or the Air Change Rate (ACH) for a heating season by tests in case of natural ventilation, involve certai
Since 2006, the French Energy Performance regulation, named RT, has been allowing two ways to justify building airtightness: either with a measurement or with the application of a quality management approach.
