EN 16798-7:2017 considers that windows on roofs that have a pitch below 60° are not included on the windward side whatever their orientation. It means that…
In Austria the lack of guidelines or standards has caused many discussions and disputes on the question if “sufficient ventilation” can be ensured with…
Wind-driven single-sided ventilation (SSV) is present in many existing buildings across Europe and with new Near Zero Energy Building (NZEB) regulations for…
Occupants in residential buildings usually control natural ventilation through window openings. However, few studies have developed simple rules based on…
In future years the frequency, duration and magnitude of extreme heat events, such as heat waves, is expected to increase due to climate change. The…
In the context of climate change, Building Performance Simulations are used to assess the ability of passive buildings to maintain…
Many European programs offer eco-conditioned financial aid to support public policies for the decarbonization of buildings. This is the case, for example,…
Room pressure differential is an important aspect in order to guarantee sufficient contamination control, but is difficult to control in airtight cleanrooms…
By 2050, the European council proposed to achieve total decarbonization in buildings. In this way, building energy models are key factors to predict the…
While the importance of air barrier systems in buildings has been understood for decades, it is only in the past decade or so that they have been given…
With the constant evolution of the French EP-regulations, good building airtightness has become mandatory to reach required energy performance. More than 60…
Worldwide, the demand for airtightness tests of tall buildings with a height of approximately 100 m is increasing. This report provides information on the…
Building air infiltration rate is required as an important input in the calculation of building heat loss. Tests to directly measure infiltration rates…
Air leakage in building envelopes is responsible for a large portion of the building’s heating and cooling requirements. Therefore, fast and reliable…
As part of the mandated standards for estimating the energy performance of buildings CEN 16798-1 and -2 was developed to provide input for the indoor…
Ventilation and air cleaning of interior spaces are promising methods for the reduction of airborne pathogen spread and may reduce the number of (airborne)…
ASHRAE’s 2022 publication of a new position document on indoor carbon dioxide (CO2) has been a significant contribution to ongoing discussions of how indoor…
The Airborne Infection Reduction through Building Operation and Design for SARS-CoV-2 (AIRBODS ) project aim is to deliver guidance on the ventilation…
There is large amount of research on COVID-19 infections including the spread and removal mechanisms of the virus in indoor spaces. Ventilation, air…
Air cleaning has been considered an alternative method of improving indoor air quality and, in some cases, as a supplement to ventilation. The need for…
