LoginA large opening has to be designed at the bottom of a Void (light-well in high-rise apartment building) in order to keep the indoor air quality (IAQ) acceptable, because of the exhaust gas discharge of the gas water-heater.
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.
A numerical investigation has been made on the effect of thermal and mass buoyancy forces on the development of laminar mixed convection between vertical parallel plates with uniform wall heat and mass fluxes.
The notion of comfort is not easy to define.
Today the term of comfort includes the different aspects of indoor air quality, thermal, acoustical and visual comfort.Standardisation working groups have already worked in those different fields, and some standards already exist but it will certa
The technical literature very often refers to the international standard ISO 7730.
A heatlhy environment at work has become a real preoccupation.
Three experiments aiming at improving the atmosphere in industrial premices are described in this paper.
In France, air quality in working areas is a matter of preoccupation for both the industry and the welfare state, that is in charge with the application of the rules and regulations in that field.
Up to now, the use of a single HVAC unit to handle ventilation along with mechanical cooling was the aim of designers : it permitted to curb the cost of a building's mechanical system.
This paper is a report on humidity control in schools mainly located in hot and humid climates : according to the US Department of Energy's investigation, most of them, use packaged cooling equipments that are not able to manage space humidit
An effective and successful O&M (operation and maintenance) program for schools begins at the very start of the project and not at its facility completion : key design issues must be covered during planning and design phases.
In this article the author gives some guidelines and techniques to conduct IAQ investigations at low cost for school staff with small budgets : first he advises occupant interviews, followed by a physical survey of the premices.
Air quality in conditioned spaces can be improved even in humid locations, in Florida.
In air-based systems, ducts deliver heat and cool air to conditioned spaces. Taking extra time to properly seal ducts during the installation along with repairing and patching leaks in HVAC duct systems will save cooling, heating and fan energy.
A good indoor air quality is necessary to minimize exposure to airborne pollutants. The main source of those pollutants is often outdoor air.
The model estimations aimed at identifying the most important parameters that determine air change rate along with predicting the indoor radon concentration to be expected in new Dutch dwellings under different ventilation conditions.Measurements
The impact of the concentration of pollutants in the air on emissions from building materials is the subject of that study.Different building materials were studied in ventilated small-scale test chambers.
It is a basic biological truth that people bring different levels of responsiveness to irritant stimuli to work.
DVC is a new energy saving technology, buildings that use a DVC strategy use CO2 sensors that measure and regulate the amount of outdoor air supplied to the space.Standards and local building codes have been slow to adopt it.Available data suggest
The purpose of that study was to quantify the effect of the variables (previously identified during the first phase of that study conducted from 1999 to 2002) concerning smoking room performance under controlled laboratory conditions.In a test cha
