LoginThe capability of HVAC systems is of interest when contracting specific function criteria such as room temperature. The probability of maintaining the criteria reflects the risk the building contractor will take when giving guarantees.
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.
The advantage of conventional personalized ventilation (PV) is to considerably improve the fresh air percentage near PV air terminal devices (ATDs). However, the distribution of the fresh air percentage is very uneven in the field.
Hong Kong’s climate is sub-tropical. It has hot and humid weather during summer and more temperate weather during the winter. The façade accounts for more than 50% of the peak cooling load in office buildings.
Desiccant cooling is a potentially environmentally friendly technology which can be used to cool buildings without the use of traditional refrigerants. We have studied the operation of a desiccant cooling system in France.
The present work contains the details of an investigation of air diffusion and comfort issues of an isolation room of a hospital. Two types of cases have been chosen for a unidirectional ventilation system of the isolation room i.e.
The UK climate is moderately mild and natural ventilation by window opening and passive ‘trickle’ vents is very common.
Age-of-air is a technique for evaluating ventilation that has been actively used for over 20 years.
In this study, the measured and predicted air distribution of an active chilled beam in a typical office room is described.
The effectiveness of various methods for saving energy and improving the indoor environment in buildings depends upon the building conditions under which those methods are applied.
The rationale of an advanced natural ventilation system should be to control airflows and air temperature during winter, and to avoid unnecessary energy losses and local draught, while maintaining an adequate ventilation rate.
The suction cylinder described in this paper is a device to increase the ventilation flow rate, especially in naturally ventilated buildings. Outdoor wind is the driving force.
Convective heat and mass transfer through large internal openings play an important role in the aero-thermal behaviour of buildings. These phenomena become even more dominant in the case of naturally ventilated buildings.
This paper presents the results of tests on the two-zone airflow pattern that forms in a room with displacement ventilation under conditions of various heat sources and airflow rates.
CFD modelling can be used in the design of ventilation systems. However, simplifications in room airflow models may lead to errors and discrepancies between predictions and reality.
A formulation to analyze ventilation duct system airflows employing, as the basic unknowns, the flow rates in the channel sections and the static pressures at the channel section ends is presented.
This paper presents an evaluation of the local thermal discomfort level in a classroom equipped with cross ventilation, for a typical moderate summer day in Portugal.
An energy and cost analysis has been performed which compared a dedicated outdoor air system (DOAS) with chilled radiant cooling panel (CRCP), designed for an official building located in the hot and humid climate of Chennai, India, and an existin
The European Directive 2002/91/EC on the energy performance of buildings (the EPBD) imposes to the EU member states several different measures to achieve a more rational use of energy resources and to reduce the environmental impact of the energy
Ceiling fans are one of the more credible techniques to decrease the energy consumption for air conditioning and improve comfort.
Due to the rapid urbanization and modernization of Korea, the demand for housing has increased considerably more than in other countries.
