LoginIn modern apartment buildings with good insulation and heat recovery, often having large windows and high internal heat gains, overheating may be a serious problem not only in summer season, but also during heating season.
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.
Air handling unit (AHU) is defined as a self-contained unit that the conditions of air vary while passingthrough it and reach to the desired temperature and humidity.
To properly evaluate the performance of ventilation system, the interaction among ventilation rate, indoor air-quality, and cooling/heating load should be analyzed.
When taking measures to increase energy effectiveness it is important not to deteriorate theindoor climate.
The role of computational modelling as a development and engineering tool has recently become more significant.
This paper discusses several issues concerning the CFD analysis or car parks during fire situations.
The potential of improving perceived air quality indoors was quantified when low-polluting materials are used and when building ventilation is increased.
In many climate zones, low energy buildings will not be able to utilize natural ventilation at all times. Hence, low-energy mechanical comfort systems will still be required.
The air distribution components in a variable air volume (VAV) flow system influences the overall function of the system. A low supply air temperature and a wide working range in terms of airflow rate, facilitate high energy efficiency.
Since 2005, the Leiden University Medical Center started the building of the new departmentof children Intensive Care (IC).
A typical virtual meeting room with occupants displays different situations of airflow pattern for different locations of the air supply even though the ventilation system has the same loca-tion of the air exhaust in the room.
The European standard prEN 13779 - Ventilation for non-residential buildings [1] distinguishes four categories of decreasing air quality, ETA 1 to 4, for rooms in buildings.
Current control strategies for central air conditioning typically adopt a machine-centered, energyconsuming approach that focuses on creating constant, uniform neutrality-conditions whichmight actually be perceived by some occupants as thermal mon
Buildings with large enclosure often present unresolved problems related to energy and air flows such as unwanted thermal stratification, local overheating, uncontrolled contaminant spreading.
A typical commercial/institutional building is modeled using a computer program developed by ASHRAE as research project number RP-590.
Changes of actual load often lead to trouble with the operation of the ventilation system. The design data are no longer correct if, for any reason, the actual load has permanently changed during the usage.
Limited data exist on indoor air and environmental quality (IEQ) in schools, and how IEQ affects students’ health or performance in China.
Measuring AERs in an effective, real-time, easy and low-cost way is still a challenge, especially in China where rooms were usually naturally ventilated but not with the Heating, Ventilating and Air Conditioning (HVAC) system.
In this study, energy consumptions associated with the change in outdoor air flow rate areanalyzed based on numerical methods.
The focus on implementing cost efficiency energy efficiency measures will in all probability increase in the future, but it has been shown that trustworthy, site specific information are key features is increasing the adoption of such measures.Thi
