In this paper, the development of a radiation module coupled with a previous 3D-CFD code is described. This module takes into account the radiative heat transfer between the active surfaces, including those relative to the occupants.

A satisfying building commissioning depends on both using right models and using models right. Through 3 case studies, this paper shows how to use simulation models correctly, to commission HVAC systems.

This paper presents a tool for manual commissioning of air handling units with the idea to combine the measurements with simulations. Thus the value of the measurements will increase.

This paper points out the importance of control system in the overall operation of buildings and gives a description of practical issues in association with modern IT-oriented control systems.

The adverse health effects and costs of IAQ problems could be reduced significantly with proper use and maintenance of buildings and early detection and remediation of problems.Dissemination of information is the key to these savings. Therefore, the Finnish ministries responsible for IAQ decided to launch an education and information campaign IndoorClimate 2002. The activities were coordinated by the Finnish Society of Indoor Air Qualityand Climate (FiSIAQ).

As the office environment is always changing new ways of looking at diffuser selection is mandatory.Changes in the office air delivery system may be due to new building codes/regulations, or to changing interior loads.New technologies allow innovative manners to treat heating and cooling needs. Some strategies may be used in retrofitting.

The study was carried out on 30 female subjects exposed in a low-polluting office in either presence or absence of personal computers that had been in service for 3 months. Under each of the two conditions, the persons performed simulated office work using low-polluting PCs. They were found to be strong indoor pollution sources, having a negative impact on perceived air quality, on performance of office work and on some SBS symptoms.

In the course of laboratory investigation we examined the adaptability of naive panels onindoor air quality measurements. We made the investigation on a measuring team of 45participants. We examined the measurement precision and standard deviation of themeasuring team with the help of Olf-Box. Our results show that despite the economicefficiency the number of persons in a measuring team cannot be reduced to less than 30subjects. We built a measuring system to examine the emission of indoor used materials.

A minaret of a mosque, traditionally used as a high platform to deliver adhan (the call forprayer), has greatly lost its functional significance with the invention of loudspeakers. Despiteof being a functionally redundant element, people still like to erect a minaret as a traditionalsymbol, identity and beauty of a mosque.

The provision of adequate naturally generated airflow is a vital component of energy-efficienthealthy buildings. Increasing densification in cities of today acts as a dominant influence onthe wind regime, diverting and obstructing natural wind flow to unpredictable levels.Localized air movement is often inadequate and vastly different from regional magnitudes anddirections and cannot be used as the basis of design.
