Window operation is among one of the most influential factors on indoor air quality (IAQ). In this paper, we focus modeling windows’ opening state in a real open-plan office with five windows. The IAQ was monitored over whole year along A k-Nearest Neighbor (k-NN) classification model implemented, based long time series both and outdoor environmental such as temperature relative humidity, CO2 c...

Whether by habit or necessity, people tend to spend most of their time indoors. Built-up Carbon dioxide (CO2) can lead a series negative health effects such as nausea, headache, fatigue, and so on. Thus, indoor air quality must be monitored for variety reasons. Various monitoring systems are available on the market. However, since they expensive difficult obtain, not commonly employed general p...

The indoor air quality (IAQ) of five low-energy London apartments has been assessed through the measurement 16 key pollutants, using continuous and diffusive methods across heating non-heating seasons. This case study approach aimed to assess presence pollutants within better understand role ventilation seasonal variations in quality. results indicate strong variations, driven by increased natu...

This paper is concerned with the development of a high-resolution and control-friendly optimization framework in enclosed environments that helps improve thermal comfort, indoor air quality (IAQ), and energy costs of heating, ventilation and air conditioning (HVAC) system simultaneously. A computational fluid dynamics (CFD)-based optimization method which couples algorithms implemented in Matla...

Poor indoor air quality affects the health of occupants a given structure or building. It reduces effectiveness learning and work efficiency. Among many pollutants, PM 2.5 10 dusts are extremely important. They can be eliminated using mechanical ventilation equipped with filters. Façade devices used as way to improve (IAQ) in existing buildings. For their analysis, researchers carbon dioxide tr...

BACKGROUND Relationships between indoor air quality (IAQ) found in schools and the allergic and respiratory health of schoolchildren have been insufficiently explored. A survey was conducted in a large sample of classrooms of primary schools in France to provide objective assessments of IAQ to which young schoolchildren are exposed in classrooms, and to relate exposure to major air pollutants f...

Decomposition of formaldehyde (HCHO) by a microplasma reactor in order to improve Indoor Air Quality (IAQ) was achieved. HCHO was removed from air using one pass through reactor treatment (5 L/min). From an initial concentration of HCHO of 0.7 ppm about 96% was removed in one pass treatment using a discharge power of 0.3 W provided by a high voltage amplifier and a Marx Generator with MOSFET s...

Guests’ evaluation of indoor environmental quality (IEQ) is important for identifying environment problems in hotels and improving service quality. This paper aims to identify IEQ budget China improve them. Specifically, 2.06 million online reviews were used assess issues China’s four areas: acoustic environment, luminous air (IAQ) thermal environment. The influences the season, region type cus...

Around 50% of the world's population, particularly in developing countries, uses biomass as one of the most common fuels. Biomass combustion releases a considerable amount of various incomplete combustion products, including particulate matter (PM) and polycyclic aromatic hydrocarbons (PAHs). The paper presents the results of Indoor Air Quality (IAQ) measurements in six houses equipped with woo...
