Heat losses from dwellings.

               

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.

Improvement in French insulation techniques for opaque parts of the envelope.

In the field of insulation techniques, technical advances are mainly due to an interactive approach resulting from three complementary factors: * National building standards and government supported incentive programmes which aim to increase the thermal efficiency of residential and commercial buildings. * Research and Development programmes set up by manufacturers in order to lead to new or improved insulation materials or components with increasing R-values. * New construction techniques used by designers and builders to reduce heat loss through building envelopes.
