TL;DR: The study presented here provides data on compared outdoor and indoor concentration levels in school buildings, as well as information on the parameters influencing the relationship between outdoor and indoors air quality.

TL;DR: In this article, a two-step analysis of night ventilation as a way of cooling office buildings and providing comfort in summer is presented, where experimental data first allows us to discuss some factors which affect the performance of the technique, to show that significant comfort improvement may be obtained in well-designed rooms, and to investigate the energy removal from the building by defining a potential energy efficiency index.

TL;DR: In this article, a multivariate observation-based statistical method was used to determine the parameters influencing the relationship between the outdoor and indoor concentration levels, and the main conclusions arising from the study are: (1) the influence of the room occupancy on the particle concentrations indoors changes with different particle sizes, (2) the building air-tightness and the outdoor concentration level greatly influence the indoor/outdoor (I / O ) concentration ratios of ozone, and (3) indoor ozone and particles concentrations are negatively correlated, which may be the result of complex homogeneous and/or

TL;DR: This paper aims at investigating a methodology based on an analysis of the material porosity first and then the application of Carniglia's mathematical model to determine the effective diffusivity of gaseous species in building materials, validating Carnigslia's methodology.

TL;DR: In this study, a factorial experiment design analysis technique was used to show the impact of three factors, VOC gas phase concentration, relative humidity, and VOC type, as single parameters and as a combination, on the adsorption process (sink effect), to better understand the interaction between these parameters.
