The 36th AIVC Conference " Effective ventilation in high performance buildings", was held in Madrid, Spain, 23-24 September 2015. Contains 119 papers and extended summaries.
Airtight duct systems [a simple way of improving a building’s energy efficiency without increased investment] | 2015 | English
This presentation will explain what exactly calibration should mean.
Uncertainty in airflow rate estimation of daytime ventilation associated with atmospheric stability | 2015 | English | 9 pp
We conducted observations of wind velocity profiles above a high-density area in Tokyo, Japan, using a Doppler LIDAR system.
Numerical evaluation of the airtightness impact on airflow pattern in mechanically ventilated dwellings in France | 2015 | English | 11 pp
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.
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.
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.
Building airtightness in Germany is on a good way. The latest survey amongst FLiB members shows the n50-values are much better than the benchmarks given in EnEV 2014 (German EPBD).
Laboratory investigation on the durability of taped joints in exterior air barrier applications | 2015 | English | 9 pp
In timber frame construction in Europe air barrier systems are typically realised at the interior side of the building envelope.
Impact of air infiltration rates on moisture buffering effect of wooden surfaces | 2015 | English | 10 pp
Interior wooden surfaces have the capacity to buffer the maxima and minima of relative humidity (RH) indoors.
Airtightness Data and Characteristics of 752 Residential Units of Reinforced Concrete Buildings in Korea | 2015 | English | 9 pp
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.
The paper presents airtightness measurements results of the multi-family building.
Hand-written results are a thing of the past. See how your phone or tablet and common testing gear can perform an automated cloud based test with secure data storage.
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
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.
Analysis of results from ATTMA lodgement –what are the realistic air permeability characteristics of UK housing | 2015 | English | 1 pp
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.
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.
Airtightness Quality Management Approaches in France: end and birth of a scheme. Previous and new schemes overview and analysis | 2015 | English | 10 pp
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.
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
Detailed numerical modelling of moist air flow through a complex airtightness defect | 2015 | English | 10 pp
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.
6 years of envelope airtightness measurements performed by French certified operators: analyses of about 65,000 tests | 2015 | English | 11 pp
Since 2000, the French EP-calculations have been considering thermal losses due to building envelope airtightness.
