The commitment to improving the energy efficiency of buildings by 2030, with the goal of achieving carbon neutrality by 2050, has been triggered by environmental challenges and the increasing scarcity of energy resources.
How to design a resilient building? Lessons learnt from an architectural view | 2024 | English | 6 pp
The EIA EBC Annex 80 Resilient Cooling program has focused on bringing together and extending the knowledge on the resilience of buildings to overheating (Holzer, 2024). In the context of the Annex 80 Resilient Cooling program
The increasing frequency and intensity of heatwaves highlight the necessity for resilient building design to reduce heat-stress-related discomfort and mortality among occupants.
Ventilation guidelines for Flemish childcare and psychological care centres | 2024 | English | 10 pp
Since the COVID-19 pandemic, governments have expressed the need for practical ventilation guidelines to maintain acceptable indoor air quality (IAQ) in the public care sector, where vulnerable groups reside.
French regulation regarding residential ventilation dates from 1982. Almost every new residential buildings constructed since then are equipped with a mechanical ventilation system.
In Belgium, the requirements for ventilation in buildings can be found in national ventilation standards, national health regulation and in regional environmental regulations and EPB regulations (Energy Performance and Indoor Cl
This paper provides a background regarding building ventilation regulations and inspection requirements in Ireland.
In Spain, the construction sector has undergone significant changes over the last twenty years due to new ventilation standards driven by increased awareness of indoor air quality (IAQ) and energy efficiency, as well as environm

The objective of this study is to assess the ability to mitigate the airborne particle concentration in a mechanically ventilated meeting room with stand-alone air cleaners (ACs) as function of the amount and type of devices, th
Assessment of Airborne Cross-infection Risk Across Various Body Orientations in Indoor Airflow Environments | 2024 | English | 2 pp
This study aims to evaluate airborne cross-infection risk under different discharge angle (-20°, 0°, and +20°) and supply temperatures (18, 25, and 30 °C) of an air-conditioner, with various body orientations (face-to-face, side
Airborne transmission in a meeting room with mixing and displacement ventilation | 2024 | English | 7 pp
The main purpose of this study is to analyse the effects of heat gain, airflow rate, air distribution, and the location of an infector on the airborne transmission and infection probability in a meeting room.
Quantifying ventilation rates in heterogeneous rooms based on point measurements of carbon dioxide | 2024 | English | 3 pp
Indoor air quality (IAQ) is increasingly accepted as a leading factor in human health, and the ventilation of our indoor spaces is a key modifier of IAQ as the principal means by which indoor pollutants are diluted.
The field of building ventilation and indoor air quality (IAQ) often employs indoor CO2 concentrations as an indicator of outdoor air ventilation rates and, in some cases, as a contaminant impacting human health and comfort.
Room integrity tests and registration of the actual situation regarding the fire protection and holding times in fire compartments in Greece | 2024 | English | 5 pp
The need of maximum airtightness is essential in order to ensure that the fire compartment can maintain the required concentration of suppression gas for a specified duration and effectively suppress or extinguish a fire.
Thermally activated building systems (TABS) are gaining attention as a means of realizing comfort and energy efficiency in office spaces.
