LoginThe current policies and regulatory frameworks in the construction sector aim to improve energy efficiency of new buildings whilst maintaining acceptable level of indoor environmental quality (IEQ) including indoor air quality (IAQ).
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.
With increasing building airtightness, the design of an adequate ventilation system gains importance.
Buildings typically are expected to provide their inhabitants with the opportunity to influence the indoor environment using various control devices. These include, for example, windows, luminaires, radiators, and shading elements.
Various studies show a deterioration in indoor air quality after renovation and energy saving measures.
The current development in building energy efficiency towards nearly-zero energy buildings (nZEB) represents a number of new challenges to design and construction.
Annex 5 – the Air Infiltration and Ventilation Centre annual report 2018.
To achieve stringent energy objectives, new dwellings are subject to energy conservation measures including low air permeability and high levels of insulation.
In these three presentations, we review the origins and history of the Indoor Environmental Quality Global Alliance, AIVC’s view of the potential value of IEQ-GA, and directions it is taking and may take over the next decade.
The interest in phase change materials (PCMs) as a solution for thermal energy storage has been growing for the last decades. It is clear that PCMs are promising for reducing the summer heat peaks without increasing the energy demand for cooling.
Controlled Natural Ventilation (CNV) is one of the potential most effective passive cooling technique to reduce cooling needs of buildings in temperate-hot climate zones.
The concentration of carbon dioxide is used as an important index of indoor air quality representative of body odor or bioeffluents in Japan. In the construction field of Japan, there is a CO2 concentration standard of a thousand ppm or less.
In a recently built zero-carbon neighborhood, demand controlled exhaust ventilation systems (DCMEV) and mechanical ventilation systems with heat recovery (MVHR) are compared under operational conditions, with focus on the energy performance of bot
Occupants control indoor environments to meet their individual needs for comfort.
Mechanical ventilation systems with heat recovery are considered the most optimal systems for residential ventilation. This research focuses on decentralized ventilation which do not need any ducting.
Buildings represent a major end use of energy throughout the world and are typically the dominant sector for electricity.
Advancing energy efficient renovation solutions in buildings necessitate adopting high-insulation and airtightness to avoid heat loss through transmission and infiltration, which can result in overheating.
Product connectivity makes products and systems remotely controllable and possibly interoperable with other devices in the house.
Earlier field measurements in Low Energy Buildings have shown that excess temperatures can easily occur during summertime in well-insulated houses, also in northern part of Europe.
The use of heat recovery ventilation systems is becoming more and more common. It is clear that these systems contribute to energy efficiency and good indoor air quality. Still there is room for improvement.
Balanced ventilation units are well known to provide a sufficient amount of fresh air in residential buildings in a controlled way, without relying on ever-changing naturally driven forces.
