LoginThe infiltration term in the building energy balance equation is one of the least understood and most difficult to model.
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.
This research evaluated the effectiveness of local supply ventilation in controlling air quality at or near workers’ breathing zones in livestock confinement buildings.
Air age is an important index to evaluate indoor air quality in ventilated rooms. The traditional definition of air age is limited to the indoor part (i.e., the air age at the inlets of air supply diffusers is assumed to be zero).
A new generally applicable model for calculating the surface emissions of VOCs (volatile organic compounds) from building materials and the VOC instantaneous distributions in the materials is developed.
Direct comparison measurements were made between various prime/storm window combinations and a well-weatherstripped, single-hung replacement window with a low-e selective glazing.
This paper focuses on the experimental research of developing models to effectively predict the dynamic whole body and local thermal comfort under highly transient conditions. Two approaches were taken subsequently.
This paper focuses on the mathematical modeling of dynamic human thermal comfort under highly transient conditions for automotive applications. A combined physiological and psychological modeling approach was taken.
Fountain and Huizenga (1995) conducted a comprehensive literature review of thermal comfort models. Significant advances in thermal comfort modeling have been achieved since that review.
This paper presents the main findings of Project HIT.2000.25 supported by the Scientific Research Foundation of Harbin Institute of Technology, a field study of indoor climates and occupant comfort in 66 residential buildings in Harbin, located in
The purpose of the current study is to compare experimental thermal comfort results with those predicted by the Fanger model.
The author points out the importance of a good selection of the dimensions of swirl air diffusers, using data provided by the manufacturers. It also gives information about the method for deciding of their number and position in the room.
The article discusses the design of the system with heat recovery to be used for the ventilation/air conditioning of a swimming pool building, in which air reaches high temperatures and humidities.
Using results from dynamic simulations, the article compares the energy consumption for the air conditioning of an industrial building with mixing and displacement ventilation.
Describes the principle of ground heat exchangers for outside fresh air, giving indications about their design rules and their energy performance, as well as recommendations for their hygienic operation.
The question is if the dedicated outdoor air systems can meet ASHRAE's air change design criteria. The standard 62 air change per hour design criteria does not inhibit the use of a separate constant volume ventilation air system (DOAS).
This paper deals with the comparison of two kind of methods for cleaning of air ducts. One is mechanical brushing with different brushes and the second one with compressed air cleaning.
The use of humidistats to control air conditioners may create mold problems mainly in houses unoccupied for an extended period. This article looks for the best approach to control humidity in empty homes during hot and humid summers.
The intent of this paper is to show that using Equation 6-1 from ASHRAE standard 62 based on occupancy is a non sense if used as a control algorithm in so far as up to now no sensors can physically count each individual in the space.
Several configurations of air to air ERHXs exist, they include heat recovery ventilators and energy recovery ventilators.
Thermal comfort is a concept quite complex that uses various phenomena, so the methods chosen for its evaluation are different according to the aspects one is interested in.
