LoginTo investigate the effect of ventilation on indoor radon (222Rn), simultaneous measurements of radon concentrations and air change rates were made in 117 Danish naturally ventilated slab-on-grade houses built during the period 1984-1989.
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.
In a way most heat pumps recover or reclaim heat energy for space heating and cooling, water heating or process heating.
The paper examines the extent to which user's intervention may compromise the therrmal performance of small sunspaces in the context of a Solar Energy Demonstration Project at Easthall in Glasgow (55°52'N), which was monitored from September 1992
Central Europe is, especially in the residential sector, a region using mainly hydronic systems with static heat transfer surfaces, which operate noiselessly and with slow air movements. Cooling is - as yet - not required.
Research scientists at the BRE and De Montford University have carried out tests examining the performance and operation of stack ventilation systems in auditoria.
The subject of this study was the indoor air quality of schools with natural ventilation in La Coruna (Spain). We took as reference the C02 H2O and CO contents of both the indoor and outdoor air.
The CO2, H2O and CO content of the indoor and outdoor air in the four libraries of the University of La Coruiia (Spain) was monitored for 48 hours.
This paper involves assessing radon concentrations at the heating, ventilating and air conditioning (HV AC) environment of Hong Kong University of Science of Technology (HKUST).
This paper reports on the experimental results using a standard room chamber to evaluate the impact of various parameters on indoor radon concentrations.
This paper describes the management of radon concentrations at the Hong Kong University of Science and Technology (HKUST).
The results from the Norwegian project "Indoor Environment in Schools" show a reduction from about 80 % to 55 % in complaints of poor indoor air quality just after renovation, and to 10 % after another year.
In a university building in Boston, IAQ complaints prompted an increase in outdoor air ventilation, causing a large increase in energy use. C02 readings were then taken in an auditorium, cafeteria, offices, and classrooms.
The purpose of the study was to assess actual ventilation, indoor air quality and also the quality of repairing process in the Finnish schools.
In March of 1996, a new Elementary School was occupied which is the first in the United States to utilize the concept of displacement ventilation as the primary means of providing both good indoor air quality and thermal comfort.
