14/05/2018 - Reduction of fans noise : a research project at CETIAT
Ignacio Zurbano Fernandez chose Cetiat to make his stage research. He works on the experimental investigation of innovative noise reduction techniques applied to full-size fan prototypes.

The project "Reduction of the broadband noise of centrifugal fans used on HVAC in buildings" is funded by the European Union’s Horizon 2020 research and innovation programme under the Marie Sklodowska-Curie grant agreement n°722401 ("SmartAnswer").

20/03/2018 - Smart ventilation for buildings
A working group of AIVC experts from several countries was created in order to exchange and disseminate information on smart ventilation for buildings. One of its tasks was to agree on a definition of smart ventilation.

CETIAT participated to this working group and is one of the authors of an information paper whose purpose is to present and illustrate this definition of smart ventilation.

06/03/2018 - AIVC Webinar - IAQ sensors for smart ventilation of buildings
An international webinar on IAQ sensors for smart ventilation of buildings was organised by AIVC on 6 march 2018 and has been a success with more than 190 participants.
The objective of this webinar was:
- to show an overview of the available low cost sensors for indoor air measurements (particulates, VOCs, CO2);
- to present results of two recent laboratory and on site evaluations of some sensors (LBNL and CETIAT);
- to assess their applicability to ventilation system control.

CETIAT was one of the 3 speakers in this webinar to present an assessment of low-cost particulate and VOC sensors.

The presentation is on our Youtube channel.

01/04/2017 - Acoustic signature of heat pumps: CETIAT involved in a new international project
CETIAT participates to a new project of the International Energy Agency about the acoustic signature of heat pumps (Annex 51 of the IEA Programme on Heat Pumping Technologies). The primary aim is to increase the acceptance of heat pumps with respect to their noise and vibrations. A second focus is to disseminate knowledge at different levels (manufacturers, acoustic consultants, installers, legislators).

The project (2017-2020) will concern air-to-water, water-to-air, air-to-air and brine-to-water units. CETIAT will represent France in cooperation with Cetim. The other participating countries are Austria, Germany and Sweden.
