LoginThis paper presents temperature and airflow measurements proving that ground-coupled fresh air intake ducts can have a significant cooling effect.
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 effect on Indoor Air quality of painting at home has been debated.
The objective of this study has been to clarify to what extent ozone (O3) and O3 /limonene in interaction with surface materials has an impact on the indoor air quality in typical low-polluting offices at realistic outdoor air change rates.
We have investigated the effect of UVC on IAQ in a ventilation plant in a typical office building. The UVC-system consisted of UVC-lights for irradiation on all central components in the air handling unit.
A CO2 level of 1000 ppm is very often used as reference for control and design of ventilation flow rates in buildings. This level is well accepted in practice, and is thus normally not given any further considerations.
A number of computer simulation case studies have been conducted with the objective of investigating the potential for energy savings in buildings with variable air volume (VAV) systems and demand controlled ventilation (DCV), compared to building
Low winter humidity indoors has a negative effect on the performance of office work | 2003 | English
Thirty subjects (17 female) were exposed for 5 hours in a climate chamber to clean air at 5%, 15%, 25% and 35% RH at 22 °C, in balanced order.
An evaluation of different ventilation principles and their application in various premises like bars and restaurants has been conducted. Measurements of nicotine concentrations revealed a strong dependency on ventilation solutions.
A SUSTAINABLE BUILDING DESIGNED FOR A COLD CLIMATE WITH EXTENSIVE USE OF INFORMATION TECHNOLOGY In the past, Telenor’s operations in Bergen have been spread across many sites and buildings.
Background. A low ventilation rate has been shown to increase the risk for health and comfort problems in offices. However, very few studies have investigated the impact of ventilation rate at home on health effects, (Wargocki et al. 2002).
This paper describes a study of reduced performance of mechanical exhaust systems in 42 Dutch houses after several years of operation.
The annual energy cost and first cost of the HVAC system, life-cycle costs (LCC) and benefits of improved productivity were simulated in an office building located in a cold climate when improvements of air quality were made by increasing the outd
Historically, industrial buildings have been simple constructions with no insulation. Ventilation has been natural through openings in the walls and in the roof.
The new perspective technology in building heat supply and climatisation, are given in this paper.
This article provides information on the characteristic heat-related data of the enclosing constructions of the existing multi-apartment houses in Latvia as well as those of the sanitation systems in these houses.Monitoring of the heat energy cons
Twenty terrace houses without heating system has been built in Sweden. The houses are extremely well insulated and very airtight. They are also quipped with a high efficiency ventilation heat recovery system.
The aim of this project has been to provide information on energy consumption in different building categories. Previous studies have focused on total energy use and not on how the consumption of energy is divided in various categories.
Optimum air distribution system should provide the basic requirements of healthy environment in the Operating Theatre, which depends in turn mainly on the air supply, extract outlet positions, and the operating table orientation.
Theoretically if the thermal properties of a building envelope and the power of the HVAC systems are known, then air infiltration becomes the only one unknown component of the thermal balance of a building and could be defined from it.
