Volume content
In a context of energy use reduction, low energy buildings are becoming more widespread. This kind of construction requires a good envelop airtightness to…
Energy efficient buildings are getting more and more airtight to avoid thermal losses through uncontrolled air leakage and rely more and more on mechanical…
Single-family and low-rise multifamily homes in the United States have become tighter to save energy and enhance comfort. To ensure acceptable indoor air…
For years, ventilation and air-conditioning systems have played an increasingly important role in ensuring sufficient air exchange in buildings. With time…
Calcium Silicate fire protection boards can be used to construct fireproof ductwork for smoke extraction and/or HVAC services. In this paper, the…
In a context of energy savings, new buildings are becoming more and more airtight. The good indoor air quality (IAQ) relies therefore more and more on…
Control of HVAC systems may reduce congestion of the electricity grid on district level by shifting energy demand of buildings and increase the self-…
The placement of mobile air cleaners (MACs) in classrooms was widely discussed between parents, teachers, and authorities in Germany during the peak of…
Indoor Air quality (IAQ) of dwellings is the result of several sources and processes, and the impact of ventilation system is the one amongst many others.…
Within the ventilation principle of buildings, the outdoor air is considered as a source of fresh, "clean" air. However, as we all know, this is not always…
Outdoor air is usually considered as a source of clean air in building ventilation principles. Although outdoor air quality has already improved in our…
Airtight and highly insulated buildings are subjected to overheating risks, even in moderate climates, due to unforeseeable events like frequent heatwaves…
The use of the word “resilience” has increased significantly since 2010, however, there is a lack of understanding around 1) how thermal resilience is…
Urban settings change the microclimate around buildings and resulting thermal comfort inside. This paper presents a method to consider microclimatic…
Current HVAC control systems assume occupant-related information, i.e., preferences, occupancy and behaviour. Furthermore, occupants often have limited…
In the frame of the project Flux50 smart ventilation, researchers and industrials aim at qualifying ventilation in mid-sized buildings through…
A smart ventilation system is able to continually adjust itself to provide the desired indoor air quality (IAQ) while minimizing energy use, utility bills,…
The serious social and health crisis faced as a result of the spread of SARS-Cov 2 has highlighted the weaknesses of human beings but has mainly highlighted…
Airborne transmission has been widely proven to be the main means of contagion of SARS-CoV-2 (Severe Acute Respiratory Syndrome Coronavirus 2) , as multiple…
This paper touches on historic indicators of good hospital design such as sun, daylight and natural ventilation. Evidence is provided that recent trends in…
