This study used a mathematical model to explore the accuracy of extrapolating multi-point blower door test results down to lower pressures at which building infiltration usually occurs naturally.
Steven Rogers
The impinging jet ventilation system (hereinafter referred to as IJV) has been proposed as a new air conditioning ventilation system. Properties of indoor environment with this system using impinging jet are complicated.
Mako Matsuzaki, Tomohiro Kobayashi, Toshio Yamanaka, Narae Choi, Haruna Yamasawa
Ventilative cooling can be used as a passive cooling measure to reduce the cooling energy demand of buildings. It can be used during the day, directly removing excessive heat gains, or during the night (i.e.

The outdoor climate is changing and the airtightness and insulation levels of residential buildings are improving. During the warmer season this can lead to overheating problems, especially when the house is situated in urban areas.
Bart Cremers
Many studies have shown that the use of mixed-mode cooling can bring down the cooling load significantly while maintaining satisfactory in door air quality and thermal comfort.
Jie Han, Wenheng Zheng, Guoqiang Zhang
For several years indoor comfort is measured in halls of hospitals by architecture students from the Delft University of Technology.
R.M.J. Bokel. P.J.W. van den Engel, A.M. Eijkelenboom, M.A. Ortiz Sanchez
Adaptive thermal comfort model has been widely used to evaluate the thermal comfort level of natural ventilation buildings.However, current adaptive standards offer a simple linear relationship between the outdoor temperature and the indoor comfor

Ventilation is critical in interpreting indoor air quality (IAQ), yet few IAQ assessments report ventilation rates; even when they do, the measurement method is often not fully described.
Sarah L. Paralovo, Maarten Spruyt, Joris Lauwers, Borislav Lazarov, Marianne Stranger, Jelle Laverge
Measuring ventilation rates in occupied dwellings is challenging but represents the conditions that occupants experience.
Jessica Few, Clifford Elwell
Infiltration is an uncontrolled contribution to ventilation in a building and can contribute significantly to the total ventilation rate, particularly in older, leaky, dwellings which can rely on infiltration to provide adequate indoor air quality
Jessica Few, David Allinson, Clifford Elwell
Indoor air quality is the chemical, physical and biological properties that indoor air must have to not cause any negative impact on occupants’ health and provide comfort: feel fresh, pleasant and stimulating. 
Maria Marrero, Manuel Gameiro da Silva, Leslie Norford
Installing Natural Ventilation (NV) system in office buildings leads to the reduction of energy consumption of heating, ventilation and air conditioning (HVAC), which accounts for approximately 50% of total in an office building in Japan.
Haruna Yamasawa, Toshio Yamanaka, Tomohiro Kobayashi, Jihui Yuan
Building energy simulation (BES) and Airflow network (AFN) programs generally incorporate wind pressure coefficients (Cp) estimated from secondary sources, namely data bases or analytical models.
Matthieu Zubialde-Elzaurdia, Franck Lucas, Alain Bastide
This study aims to experimentally evaluate the influence of the combination of a supply only ventilation, called here positive input ventilation, and innovative active air vents on the Indoor Air Quality of a house.
Antoine Leconte, Clément Lafféter, Thomas Fritsch, Nicolas Giordano, Julien Escaich, Ophélie Ouvrier Bonnaz
Guaranteeing high indoor air quality and high degree of user satisfaction at the same time is one of the challenges when improving the energy efficiency of a building.
Leonie Scheuring, Bernhard Weller
The mainstream of air-conditioning system for medium and small sized buildings is conditionally air mixing ventilation with ceiling cassette unit of packaged air conditioner (PAC), however, it may bring a high cold-draught risk to occupants, due t
Shogo Ito, Toshio Yamanaka, Tomohiro Kobayashi, Jihui Yuan, Narae Choi
Recently in Japan, many buildings introduce packaged air-conditioner (hereinafter, this is called “PAC”) as an air conditioning equipment.
Norikazu Yasuda, Toshio Yamanaka, Tomohiro Kobayashi, Jihui Yuan, Choi Narae
The present paper describes the design improvement of a single-room ventilation unit. This ventilation system presents many advantages, however, several drawbacks exist. The first one is the acoustic disturbance.
Antoine Parthoens, Luc Prieels, Jean-Jacques Embrechts, Yves Detandt, Sébastien Pecceu, Samuel Gendebien, Vincent Lemort
The purpose of this paper is to summarize the status of promising low carbon building services solutions fitted for a low emission building stock in urban areas.
