LoginThe present study aimed at assessing six commercially-available in-duct air cleaning devices which are designed to be mounted in the central ventilation system of offices or commercial buildings.
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.
Open joint ventilated façade (OJVF) is a passive constructive system widely used to ameliorate envelop of buildings, improving their energy efficiency.
Because of the customer need of best possible comfort condition and satisfaction, shopping centers are conditioned by means of basic HVAC systems, often without considering the potential of natural ventilation to contribute to air change rate, and
According to the International Energy Agency, buildings represent over one-third of total final energy consumption.
The differences between extract ventilation and balanced ventilation are subject of many discussions in sales markets where both solutions have their share.
Ventilation plan for smoking room must deal with pollutants since they affect the air quality of adjacent rooms.
First the Subtask will organize a literature survey and make researcher contacts to gather relevant data and existing knowledge on major pollutant sources and loads in buildings, including models. Laboratory testing and model setup to provide exam
Recently the international media like in USA, Canada, UK, Denmark, Germany etc. has been discussing the issue of differences between men and women regarding thermal comfort and the preferred room temperature.
Ventilation systems can save heat energy by using heat recovery, but consume electrical energy to power the fans.
Subtask 1 of IEA EBC Annex 68 will aim at defining the metrics to enable a proper consideration of both energy and IAQ benefit in building design and operation
The energy use in buildings is dependent on the choices made during the design, construction and renovation.
Lecture rooms with their high, quickly fluctuating internal gains, e.g.
According to past researches, most people spend 80%-90% of their time indoors. The ventilation is very important to people’s health and the comfortable surroundings around us.
In determining ventilation rates, it is often necessary to combine naturally-driven ventilation, such as infiltration, with mechanical systems.
The control of heat losses, inwards/out, in nearly zero energy buildings is of high importance. The transmission losses through the building envelope are easily reduced using larger amounts of insulation.
The aim of this paper is to show the effects of variable ventilation rates on the demand of energy and air quality in dwellings, and how airtightness and wind affect this relation.
At typical indoor CO2 levels there is no scientific evidence that CO2 is harmful to comfort and health of healthy persons, though there is a potential for negative effects on some aspects of performance.
New buildings have to satisfy ever-tightening standards regarding energy efficiency and consumption. This results in higher insulation levels and lower air leakages that reduce heating demands.
Local climate change and in particular, the urban heat island, is the more documented phenomenon of climate change.
EU energy policy encourages member states and public authorities to start converting building stock into nearly Zero Energy Buildings (nZEB) and adopting exemplary actions.
