Moisture Buffering in the Indoor Environment
Moisture buffering in the indoor environment is the ability, through absorption and desorption, of surface materials to attenuate the moisture variations of the indoor air. Moisture buffering plays an important role in understanding the risks for biological growth in surface materials in the indoor …

Simplified methodology for indoor environment designs
Current design of the building indoor environment uses averaged single parameters such as air velocity, air temperature or contaminant concentration. This approach gives only general information about thermal comfort and indoor air quality, which is limiting for the design of energy efficient and …

Modeling contaminant spread and mitigation in the indoor environment
… and ventilation strategies aimed at improving indoor air quality (IAQ). As part of this effort, a model is developed to effectively estimate crack areas of the multizone testbed. The model is divided into two sub-approaches: one approach is to assume the same crack area for the same type of …

Toward an Understanding of Children’s Exposure to Semi-Volatile Organic Compounds in the Indoor Environment
… termed thirdhand smoke (THS), persist in the indoor environment and contribute to exposure is poorly understood by the public (Winickoff et al., 2009). Rehan et al. (2011) described THS as a “stealth toxin” due to its presence in places and on surfaces that are used by unsuspecting and …

An evaluation of sensory comfort components of survey questionnaires used for indoor environment problems in buildings
The efficacy of indoor environment evaluation is, in part, a function of the reliability and validity of the different measures used. This thesis presents results of a study, conducted in a building without known problems, which compares the reliability and validity of sensory comfort components …

A study on the indoor environment quality: its impact on occupants’ productivity of university library (Wolverhampton University libraries as an example)
Indoor Environmental Quality (IEQ) determines occupant comfort, health, and productivity within built environments. As essential academic spaces, university libraries enhance student learning, research, and overall academic performance. While previous studies have primarily examined the health and …

Indoor environment and the impact on the health of pre-existing asthmatics at work: the development of a risk management framework
… in exposures in Guernsey and assessment in indoor environments showed that real-time analysis of NO<sub><sup>2</sup></sub> levels needs to be undertaken if indoor micro environments for NO<sub><sup>2</sup></sub> are the be assessed adequately. There was temporal and spatial variation in …
