LoginThis paper presents an overview of what is known related to particulate matter indoors. An information for understanding filtration is given along with the way how particles contribute to adverse health effects.
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.
This paper emphasizes on the role of hydroxyl radicals in indoor processes, on chemical reactions occurring on indoor surfaces, and the impact of products of indoor chemistry on building occupants.
In this paper, practical recommendations for design and operation of HVAC systems are presented. The result of a proper maintenance will be less pollution and a better indoor environmental quality.
This paper is a review of almost two decades work on pollution sources in ventilation systems. There is a special emphasis on ventilation filters with reference to the work of other researchers.
The mathematical model described in this paper relates position, velocity and aerodynamic Torque characteristics of air dampers. That model has been has been developed and tested experimentally : the results demonstrate its accuracy.
Thanks to an uncertainty analysis, the demonstration has been made that the APT method can, over a wide range of conditions, outperform a pitot tube, but can't do it when the damper is nearly open.
A framework and computer code has been developed in that study for coupling building energy and load calculations with room air models.
In this paper the complaint prediction model developed by Federspiel in 2000 is evaluated and recalibrated. Temperature time-series data and complaint data were collected from different size buildings from different geographical areas.
Microperforated sound absorbers have been successfully implemented in suspended ceilings, transparent panel absorbers or other applications.
The aim of that study was to evaluate the effect of compression on pressure drop in flexible, spiral wire helix core ducts used in residential and light commercial applications. Tests on ducts of 6, 8, 10 in.
That addendum 62n modifies the ANSI/ASHRAE Standard 62 "Ventilation for Acceptable Indoor Air Quality, it contains an update to the minimum prescribed ventilation rates and includes ventilation airflow "additivity" for dilution of p
In this article, the sources of risk using DCV (demand control ventilation) are examined along with the components typically and the possible ways to minimize risk without sacrificing potential energy savings.
Supply air CO2 control (SACO2) is a technique for measuring the outdoor air fraction in the supply air and controlling the outdoor air intake.
The number of Underfloor air systems (UFAD) has incresed 40 % between 1995 and 2002, thanks to the benefits it offers : lower churn costs, improved IAQ, lower energy costs, potential to reduce floor-to-ceiling heights.
This document gives an overview of the work within the area of housing and health. It defines firstly what is healthy housing, then how housing impacts on health, and deals with a survey made in 8 cities in Europe.
There are two ways for unbalanced return air to produce moisture and mold problems during hot and humid weather : - the increased entry of outdoor air that substantially increases indoor relative humidity.
This paper presents a numerical method to estimate the concentration of occupant-generated C02 for the occupancy found in elementary school classrooms with nonforced ventilation.
That study was conducted in Nashville (TN) : during six weeks, measurements using passive ozone samplers were made on a group of school children aged 10 to 12 to estimate the outdoor/indoor /personal ozone exposure.
This paper gives the description of the outline of a methodology whose aim is to decrease or even eliminate the emissions resulting from building materials.
A literature review finds that observational studies have found a correlation between exposure to VOCs and asthma, whereas interventional studies did not manage to show it.
