LoginVarious studies demonstrate a significant impact of ductwork leakage on the fan power consumption of ventilation systems.
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.
The AIVC website includes a protected content feature that provides access to AIRBASE. Access to the protected content is free of charge but requires you to register first.
Regional climate change in cities is the most documented phenomenon of climate change . Higher urban temperatures are documented experimentally for more than 450 major cities in the world.
The Proceedings of the 40th AIVC - 8th TightVent - 6th venticool Conference: "From energy crisis to sustainable indoor climate - 40 years of AIVC" held in Ghent, Belgium on 15-16 October 2019.
This presentation will cover the key lessons learned from post-occupancy evaluation of the ventilation strategies in several new-build dwellings in the UK.
Humidity-based DCV systems have been widely used in France for 35 years and are considered as a reference system, including for low-energy residential buildings.
The ventilation system removes pollutants effectively, and the resultant vertical temperature difference in the room greatly affects the indoor air distribution.
A demonstration house was previously built and commissioned in Iqaluit, Nunavut, Canada.
Building airtightness is a critical aspect for energy-efficient buildings as energy performance of a building can be reduced significantly by poor airtightness.
The trend in European countries, such as Belgium, France and Germany is that the quality of the airtightness of the building envelope is getting better and better.
Allergic symptoms are closely related to indoor allergens, such as airborne particulate matter, fungi, and house dust mite.
To date, the vast majority of indoor air quality studies have relied on repeated visits to dwellings to obtain data derived from short-term monitoring exercises, a time-consuming process that places considerable constraints on personnel, equipment
In 2017 the Danish Building and Property Agency started a project titled “Avoiding energy waste in ventilation systems” by tracking the actual energy use in a sample of their 4 million m2 portfolio of buildings through on-line energy management to
Buildings represent approximately 40% of global energy demand and heat loss induced by uncontrolled air leakage through the building fabric can represent up to one third of the heating load in a building.
Between 2017 and 2018, the Centre for Studies and Expertise on Risks, the Environment, Mobility and Planning (Cerema) organized an airtightness measurement campaign in 117 multi-family collective and single-family French dwellings.
Building dampness and mouldy indoor environments are associated with the increase of approximately 30-50% in variety of respiratory and asthma-related health outcomes through a meta-analysis.
Throughout the certification process of air filters, the major technical characteristics are evaluating. Both theoretical models and experimental methods, proves some relationships between the parameters and the performance of product.
Addressing the airtightness of the building envelope is key to achieve thermal comfort, good performance of ventilation systems and to avoid excessive energy consumption.
This study used a mathematical model to explore the accuracy of extrapolating multi-point blower door test results down to lower pressures at which building infiltration usually occurs naturally.
There is no doubt that odor is also an important factor to evaluate indoor air quality.
Across different territories there are various normative models for assessing energy demand of domestic dwellings, which use simplified approaches to account for the heat loss due to the air infiltration of a building.
