LoginPresents the conclusions of several field studies carried out in retrofitted houses in the USA and compares them with predictions from models.
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.
The AIVC website includes a protected content feature that provides access to AIRBASE. Access to the protected content is free of charge but requires you to register first.
Test structures were constructed near Madison, Wis, USA and Gulfport, Miss, USA for exposure of eight types of insulated wall panels at controlled indoor conditions and typical outdoor weather conditions.
Describes the physics of moisture in the home.
A brief synopsis of recent analytic and experimental studies is given.
Energy efficient steel buildings with better thermal insulation to reduce transmission losses are now being built in Sweden. Examples of structural design are given to minimise the influence of thermal bridges.
The current industry standard for measuring air leakage of windows, curtain walls, and doors is ASTM E283. This test measures the ability of fenestration products to resist air leakage under ideal laboratory conditions which usually are at s
This wind tunnel investigation studies the effects of surrounding buildings on the wind pressure distribution over a 1 1/2-storey single-family house.
This paper discusses the thermal effects of air flows, and some aspects of the influence of moisture and moisture transfer on the thermal performance of a structure.
Radon-222 and 222Rn progeny concentrations, barometric pressure and pressure differentials between inside and outside were measured continuously in the basement of a recently constructed energy-efficient house in metropolitan Denver, Colorado
A survey was carried out on 15 homes in Northern Italy to evaluate the occurrence of 35 selected volatile organic compounds and of total volatile organics in indoor air and in ambient (outdoor) air. Respirable suspended particulates and venti
Air flow in an enclosed space, whether from natural or mechanical ventilation, has generally a rather slow velocity, 0.1-0.25 m/s, but may still cause local discomfort.
The air velocities and air temperatures distributions within the occupied zone of a room were determined and the wall surface temperatures were measured, in steady-state conditions.
Describes approach based on the Predicted Mean Vote concept as a suitable index of discomfort for housing with evaporative cooling.
Air pollution due to volatile compounds in six unoccupied houses with intended low energy consumption was measured. The measurements included air temperature, air humidity, ventilation rate and concentration of organic gases and vapours.
The influence of air change and ageing on emissions from 5 different building materials were studied.
The sink or removal rates for two reactive indoor air contaminants (NO2 and SO2) were evaluated in an environmental chamber as a function of material type (painted sheetrock, wallpaper and carpeting), variable surface area of the material, relativ
Direct gas fired heated make-up air is used in industrial buildings to replace exhausted air and to achieve a comfortable temperature while avoiding draughts.
Person-equivalent flames are used to test the performance of ventilation taking account of human occupancy. The resulting carbon dioxide concentration is measured. Standardised bottle gas burners were found to be the most suitable gas sources.
The participating countries of Annex IX "Minimum Ventilation Rates" study emission rates and time dependence for building materials and their dependence on various factors including human behaviour; indoor transfer and interactions; control and ai
Identifies sources of gaseous, vaporous, particulate (inert and viable) and radioactive contaminants within nine functional categories of a hospital.
