Optimisation of the thermal and ventilation performance of naturally ventilated building facades.

The paper, which is based around a proposed design for a building in Germany, discusses how the facade can be used to provide the driving force for building ventilation, design constraints and the application of a zonal airflow model driven by convective heat gains, to the analysis of the performance of building.

Insulating materials and certification.

Describes the French ACERMI Certification governing thermal insulation. It aims at setting competition between products according to objective bases on both a national and international level; making it possible for the users to select products easily and under optimal saving conditions; and ensuring them, without their having to check, that the product delivered to them has the characteristics expected.
