The real estate market is changing rapidly and with it the evaluation of buildings.Requirements are being changed in order to meet market demand. Besides the location,infrastructure and the actual condition of a building's technical equipment a further parametercalled the Soft Factor is required in the evaluation of a buildings quality. High endequipped spaces, according to statistics, are more easily let and are therefore the key assets inhigher cash flow portfolios. A factor that can significantly decrease the value of a building islow air quality.

Measurements of SO2, NO2, and Suspended Particulate Matter (SPM) of indoor air andcorrelation with outdoor air have been determined in an office of multistory mechanicallyventilated building. The objective of the study was to evaluate the diversity of SO2, NO2and SPM inside building and penetration of pollutants, mostly found outside, from outsideto inside in an airtight building. Ground floor of the building was selected for study.Horizontal measurement of SO2, NO2 and SPM was done inside the building at foursampling stations.

An epidemiological cross-sectional questionnaire study on housing and health, involving 229 children in Sisimiut, was initiated in May 2006. Based on this study, a nested case-control study was carried out in August 2006, covering inspections and physical measurements in the homes of 51 children. A tendency towards a lower average CO2-concentration in the bedroom, at night, in the group of sick children (cases) compared to the group of healthy children (controls) was found.

The aim of this project was to investigate the indoor environment and building characteristics in relation to with asthma and allergy among Greenlandic children. A cross-sectional questionnaire study involving 229 children in schools and institutions in Sisimiut was performed. The response rate was 23%. Of the children included,15% had doctor-diagnosed asthma. Rhinitis and eczema within the last 12 months was associated with; visible damp stains in the childs room; mouldy, earthy, unpleasant and tobacco smell and with suspected dampness in the construction.

Clean indoor air is one of the most important factors for the welfare of the society. To understand and study the complex causality of different factors affecting indoor air quality, a databank and an IAQ-simulator have been developed. Databases have been developed to connect knowledge of material emissions to the indoor air measurement results.

Controlled milling of natural source materials has led to establishment of an allergen carrier particle sample bank for common, indoor, allergen proteins. Allergen reference powders are obtained from controlled processing of spent dust mite culture, roach colony fras, and cat and dog fur samples from pet grooming establishments.

The buildings’ environment plays a very important role in health matters and the quality of life. A series of experimental measurements were carried out in the residential sector of the greater region of Athens. Parameters influencing the indoor air quali

This study presents the first Flemish monitoring campaign on indoor air quality in children’s living environment. The main aim of the study was to determine for sensitive groups of children the indoor environment exposure a result of contaminants that occ

Half the electricity use in supermarkets derives from the display of refrigerated food. Climateinfluences the performance of the cabinets and their energy use as well as the thermal comfortof people and the temperature quality of the food. This work is an interdisciplinary study ofperceived comfort in relation to measured local climate. The aim is to define an appropriateclimate and to improve energy efficiency with maintained or even better climate for goods,staff and customers.

In order to calculate mean radiant temperature in an outdoor environment, we had to calculate a hypothetical sky temperature from directly measurement or an empirical formula of atmospheric radiation expressed as functions of daily mean air temperature, cloud amount, etc.
