In this paper a new ventilated window with a PCM heat exchanger is proposed. In winter, the heat exchanger works as a solar collector to store heat for pre-heating of the ventilated air.

Balanced ventilation units are well known to provide a sufficient amount of fresh air in residential buildings in a controlled way, without relying on ever-changing naturally driven forces.

Diffuse ceiling ventilation is a novel air distribution concept, where the space above a suspended ceiling is used as a plenum and fresh air is supplied into the occupied zone through perforations

In a sealed building with tight facades, conditions for a good indoor air quality and comfortable conditions must be guaranteed all the time especially for employees.

ADEME is a public organisation to implement public policy in the areas of the environment, energy and sustainable development.

The real performances of ventilation systems on site remains a challenge in practice. One of the most common reasons for complaints by the building occupants is the acoustic discomfort.

This presentation will summarize the last forty-five years of indoor air quality (IAQ) studies, investigations and research from the first energy crisis in the USA in the 1970’s to the latest issue

An accurate temperature gradient calculation is essential for displacement ventilation (DV) system design, since it directly relates to the calculation of supply air flow rate.
