IEQ and energy performance of residential smart ventilation strategies in France | 2024 | English | 5 pp
Smart-ventilation with airflows adapting to the need of buildings reduces energy consumptions and can improve IAQ. In some countries, smart ventilation strategies have been widely used for a long term (like Belgium, France,…).
The protection from harm to populations of people provided by Exposure Limit Values | 2024 | English | 7 pp
The protection from chronic harm provided by exposure limit values (ELVs) is evaluated for indoor air contaminants set by regulatory bodies of member countries in the Air Infiltration and Ventilation Centre (AIVC).
Health-Equivalent Energy Efficiency Factor, combined metric of harm and energy use | 2024 | English | 10 pp
The inclusion of health-based performance indicators and metrics in ventilation system design and research is a widely discussed topic in recent years.
Design of ventilative cooling systems using Ventilative cooling standards; design steps and corresponding flow diagram | 2024 | English | 4 pp
