LoginCalculating the contamination concentrations in a space or the required ventilation for a spacehas been a difficult and confusing part in the application of the IAQ Procedure ofANSI/ASHRAE Standard 62, Ventilation for Acceptable Indoor Air Quality
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.
The simulation has been performed using the CFD package SWIFT. In the first phase, meanflow and thermal comfort parameters of the integral living room of the modern family househave been calculated.
The ventilated ceiling is a flexible solution for kitchen ventilation where the heat loads arerelatively low and aesthetics is a concern. The use of hoods is an ideal solution for locallyhandling contaminants produced in concentrated areas.
An advanced supply air filtration unit has been developed, and its performance was evaluatedin the laboratory. The filter consists of an electrically enhanced particle filter and an adsorbentfilter for gases.
Whilst Computational Fluid Dynamics (CFD) has been popularly applied in indoor air andventilation research, most Personalized Ventilation (PV) research is based on experiments.This study is an attempt to seek validation of PV experimental data wit
During the construction of Dhoby Ghaut Station on the MRT North-East line a 10-storeycommercial development was completed.
In time, ventilation ducts and accessories get dirty and this may lead to malfunction of ventilationequipment, fire hazard and especially a decrease in supply air quality. Repeated cleaningof the components can prevent these adverse effects.
In northern Europe ongoing changes in legislation that require increased levels of insulation,and the sealing of houses to reduce infiltration heat loss, has led to concerns about indoor airquality.
The concept of personalized ventilation (PV) is at the cutting edge of technologicaldevelopments in the area of air-conditioning and is fundamentally based on improvingventilation to every individual in the built environment.
Two air terminal devices (ATD) for personalized ventilation (PV) were developed: RoundMovable Panel (RMP) and Headset-Incorporated Supply (Headset).
Velocity measurements were performed in the air flow resulting from two horizontal opposite air jets along a ceiling.
Today, tracer gas is used as a reliable means to examine various queries related to mechanical systems. Prerequisite is the safe and routine handling of the relevant analysis methods.
Sick building syndrome (SBS) symptoms were investigated in a laboratory study of low humidity environments: 30 subjects were exposed to clean air at 22C with 5%, 15%, 25% and 35% RH and 30 were exposed to polluted air at 18C, 22C and 26C with a co
In some indoor environment surveys, respondents are asked to recall conditions acrossseasons (e.g. to recall summer conditions during a winter survey).
We gathered exposure data on indoor air pollution and investigated the dose-response slopefactor for indoor air pollutants, such as volatile organic compounds, aldehydes and radon.Population cancer risks (that is the theoretical cancer deaths) wer
A framework for performance criteria for healthy and energy-efficient buildings was developed within the context of two European funded Projects: PeBBu and HOPE.PeBBu, Performance-Based Building, is a Thematic network under the Competitive and Sus
Healthy housing strategies tend to focus on good comfort and on avoiding specific health riskagents. These agents are generated by building features and occupancy and may come fromboth indoor and outdoor environments.
Microbial sampling was used to study indoor air quality in a building where the employees had complained about IAQ for many years.
In this study, the houses where residents were suspected of having sick house syndromelocated in Miyagi prefecture of Japan, had been investigated during the summer of 2001.
Our study conducted serial measurements of indoor air quality and sick building syndrome (SBS) of employees in eight air-conditioned office buildings to examine the association between indoor air pollution and the reporting symptoms of SBS.
