Résumé

The growing interest in natural or hybrid ventilation systems makes a challenge for good integration of openings in building fac¸ades. Acoustical treatment of building openings is complex, as many construction elements and phenomena must be considered. The proposed sample of insulated curtain wall is based on standard construction that includes an aluminum structure and windows. Firstly, evaluation of the sound insulation procured by the facade sample has been tested with all windows closed. Sound pressure levels were noted and averaged in both rooms to get the noise reduction. Using A-weighting for sound pressure levels, this analysis might reflect occupant's perception. The first test made about ventilation was to check maximal free running capacities. That consists in measuring airflow with a small deferential pressure through the fa¸ade.
