LoginThis paper demonstrates the technical considerations that are important to understanding the energy-saving potential of encouraging the use of brushless direct current (BDC) motors in residential air handlers.
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 describes the smoke control aspects of twonaturally ventilated high-rise office buildings with operable windows. One utilizes its operable windows in conjunction with an HVAC system to provide tenants with fresh air.
The aim of that study was to find out if a potential air flow from crawl space has an influence on the indoor air quality : is there a potential risk for the first floor apartments ? A balanced ventilation system is recommended.
That study carried out particle transport measurements for full-scale timber frame structure similar to a wooden floor. The penetration is highly dependent on pressure difference and not on holes in the surface boards of the structure.
The article compares the definitions and requirements in various standards (ASHRAE 62, DIN 1946, CEN CR 1752, CIBSE guide A, ISO TC 205) related to ventilation and indoor air quality in terms of health, comfort and productivity.
The study was carried out on 30 female subjects exposed in a low-polluting office in either presence or absence of personal computers that had been in service for 3 months.
As the office environment is always changing new ways of looking at diffuser selection is mandatory.Changes in the office air delivery system may be due to new building codes/regulations, or to changing interior loads.New technologies allow innova
This article sums up a detailed analysis of variable air volume (VAV) box control. Sizing criteria are provided in order to minimize the life-cycle cost in typical application.
This article focuses on the replacement air component for atrium smoke exhaust, including comparisons of three design approaches. The concepts are illustrated by case studies.
This article presents the difficulty for ASHRAE to take into account the high levels of ventilation requiries and to combine them with the demand for "guidance" encouraged by the tobacco industry and its allies.
This paper gives a description of the cleaning of metal ducts in small buildings, located in heating climates in the northern US states, with different cleaning techniques, their cost, and advices from different trade associations.
This article aims at providing an overview of recent field experience, as reported in the literature, about underfloor air distribution systems (UFAD) as an alternative to conventional air distribution.
This paper deals with a modeling approach that combines the classical heat and moisture balance differential equations along with the use of experimental time-series data.
This paper deals with a pilot study in portable classrooms where neither adequate ventilation nor associated conditioning of indoor air for occupant comfort were provided.
Re-number k-e model is the most used turbulence model in Computational fluid dynamics. But sometimes that model does not produce good results and Reynolds stress model (RSM) improves the prediction of the velocity in the jet.
A pilot questionnaire study was carried out on two groups: 128 occupants of new homes' (52 R-2000) on the one hand and 149 occupants of control homes on the other hand: both the groups were questionned to compare their general and respiratory
The purpose of that study was to measure exposure levels of phthalates and musk fragrances in typical apartments, kindergartens and to estimate their effects on health. 59 apartments and 74 kindergarten in Berlin were studied.
The aim of that study was to compare measurements of wall relative humidity (RH) to mold identification in 458 samples from 100 dwellings.
This paper provides scientific evidence that electrified homes in South African rural villages have lower levels of air pollution compared to the non-electrified homes using fuel or wood.
The aim of this paper was to examine the effect of two different dust collection devices, widely used in epidemiological studies.
