LoginThe ISO 7730: 2005 introduces three classes of thermal environments (labelled A, B, C) as afunction of the PMV range value gradually decreasing according to the need of a lower dissatisfiedpercentage.
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.
Thermal comfort very frequently affects thermal sensation in such a hot environment as Libya.
The study was carried out to answer directive 91/2002 of the UE, transcribed in Romaniathrough the law 372/2005, which requires, inter alias, the regular inspection of the installations of airconditioning.Such an inspection requires a coherent sys
The severe summer climate, the actual trends in building design (imported from northern latitudes) and the rising living standard in Mediterranean countries have promoted a massive and unnecessary use of air conditioning systems.
The utilization factor is a relative well-known concept used in some simplified calculationmethods as CEN EN-13790, in this regulation this factor depends on the thermal inertia and the ratioheat gains/ heat losses.
The passive cooling techniques such as night time cross ventilation is potentially an interesting strategy to provide substantial cooling energy savings in warm climates.
We reflect the results and conclusions of a study on the air’s motion in four old Surgery Rooms in a Basque Country (Spain) hospital that were to be reformed.
The objective of this paper is to expose the obtained results of ventilation efficiency in thetypical configurations of air extraction in residential buildings and, specifically, in the bathroomscases.
The paper is a presentation of selected results obtained by questionnaires, measurements and simulations of ventilation processes in typical blocks of flat and office buildings in Silesia.
For that study, field measurements of the indoor climate and ventilation performance have been carried out in Estonia in 28 lightweight timber-frame detached houses.
A comparison is made of the performances of various heating, ventilation and air conditioning (HVAC) arrangements in eliminating pollutants in working environmemnts in Taiwan. The airflow of various simulation routes are evaluated.
The study of the particle pollution in an office under two different ventilation modes is presented in this paper.
The aim of that study was to pinpoint indoor environmental variables necessary for providing an assessment of the condition of indoor environment in homes .
The aim of the European project HOPE (Health Optimisation Protocol for Energy-efficient buildings) is to demonstrate the energy-efficient buildings can be healthy and comfortable too for their occupants.
Results of 3 years of measurements in the chemistry department building of the university of Athens are summed up in this paper. Levels of CO, CO2, SO2, NO2, Cl2, HCHO, O3 and TVOC werre measured in laboratories, classrooms and offices.
Application of computational fluid dynamics in building design : aspects and trends | 2006 | English
The roles of CFD in building design are presented in this paper such as designing a thermally comfortable, healthy and energy-efficient building. The developing trends in applying CFD to building design are analyzed by reviewing the literature.
The ventilation system of an operating theatre in an hospital minimises the risk of airborne infection.
To investigate the effect of the headroom on de displacement ventilation (DV) system, a numerical simulation applying a validated CFD model was used. The simulation and comparison of two different headroom heights in a space was carried out.
The installation of upper-room ultraviolet germicidal irradiation (UVGI) devices in ventilated rooms can reduce the transmission of infections by an airborne route.
That study proposes an Express Assessment Protocol (EAP) to quantify IAQ problems by assessing the "dominant" contributors to unacceptable IAQ.
