Ventilation systems play an important role in providing a good indoor air quality in dwellings. Mechanical exhaust ventilation systems implement natural vents, also called trickle vents, to supply outdoor air to the dwelling.
Romy Van Gaever, Samuel Caillou, Sébastien Pecceu
Japan will have to further reduce CO2 emissions to meet its obligations under the Paris Agreement negotiated at the 2015 United Nations Climate Change Conference.
Ogawa Yohei, Shiraishi Yasuyuki
Health Canada’s cross-Canada residential radon survey report from 2012 demonstrated that roughly 7% of Canadian homes contain radon levels above the Canadian guideline of 200 Bq/m3.
Justin Berquist, Liang Grace Zhou, Jeffrey Whyte, Yunyi Ethan Li, Mark Vuotari, Gang Nong
Radon gas is a well-known building´s pollutant which can affect negatively people´s health (WHO, 2009). Radon´s source is the soil underneath buildings.
Pilar Linares-Alemparte, Sonia García-Ortega
Indoor pollutants and particles pose a threat to human health as people spend 90% of their time in indoor spaces.
Walid Chakroun, Sorour Alotaibi, Kamel Ghali, Nesreen Ghaddar
The ventilation system removes pollutants effectively, and the resultant vertical temperature difference in the room greatly affects the indoor air distribution.
Xiaorui Deng, Guangcai Gong
Building dampness and mouldy indoor environments are associated with the increase of approximately 30-50% in variety of respiratory and asthma-related health outcomes through a meta-analysis.
Kenichi Hasegawa, Naoki Kagi, Nobuhiro Kanazawa, Jun Sakaguchi, Naohide Shinohara, Yasuyuki Shiraishi, Teruaki Mitamura, Jun Fukushima
Allergic symptoms are closely related to indoor allergens, such as airborne particulate matter, fungi, and house dust mite.
Teruaki Mitamura, Kunio Dobashi, Hiroki Harasawa
There is no doubt that odor is also an important factor to evaluate indoor air quality.
Aya Eto, Narae Choi, Toshio Yamanaka, Akihisa Takemura, Tomohiro Kobayashi
To date, the vast majority of indoor air quality studies have relied on repeated visits to dwellings to obtain data derived from short-term monitoring exercises, a time-consuming process that places considerable constraints on personnel, equipment

In 2017 the Danish Building and Property Agency started a project titled “Avoiding energy waste in ventilation systems” by tracking the actual energy use in a sample of their 4 million m2 portfolio of buildings through on-line energy management to

Throughout the certification process of air filters, the major technical characteristics are evaluating. Both theoretical models and experimental methods, proves some relationships between the parameters and the performance of product.
Kiyan Vadoudi, Gregory Kelijian
In recent years, especially, the climate change (CC) and urban heat island (UHI) effects are becoming serious problems, affecting people’s life and health, especially in hot summer.
Haruto Kitakaze, Jihui Yuan, Toshio Yamanaka, Tomohiro Kobayashi
Upper floors of super-tall residential buildings have different characteristics of the exterior environment as compared to their low floors or low-rise residential buildings due to the high-rise.
Hyoeng-Tae Kim, Hee-Gang Kim, Chang-Ho Jeong, Myoung-Souk Yeo
The perimeter space near windows usually has some problems with the thermal environment which is easily affected by heat transfer and radiation from windows.
Shaoyu Sheng, Toshio Yamanaka, Tomohiro Kobayashi, Jihui Yuan, Masahiro Katou, Saori Yumino
Addressing the airtightness of the building envelope is key to achieve thermal comfort, good performance of ventilation systems and to avoid excessive energy consumption.
Irene Poza-Casado, Alberto Meiss, Miguel Ángel Padilla-Marcos, Jesús Feijó-Muñoz
Between 2017 and 2018, the Centre for Studies and Expertise on Risks, the Environment, Mobility and Planning (Cerema) organized an airtightness measurement campaign in 117 multi-family collective and single-family French dwellings.
Sylvain Berthault, Lucille Labat, Cédric Delahais, Elodie Héberlé, Sabrina Talon
The trend in European countries, such as Belgium, France and Germany is that the quality of the airtightness of the building envelope is getting better and better.

Across different territories there are various normative models for assessing energy demand of domestic dwellings, which use simplified approaches to account for the heat loss due to the air infiltration of a building.
Alan Vega Pasos, Xiaofeng Zheng, Mark Gillott, Christopher J. Wood
Buildings represent approximately 40% of global energy demand and heat loss induced by uncontrolled air leakage through the building fabric can represent up to one third of the heating load in a building.
Alan Vega Pasos, Xiaofeng Zheng, Benjamin Jones, Mark Gillott, Christopher J. Wood
