Worldwide the food system is responsible for 33% of greenhouse gas emissions. It is estimated that by 2050, the total food production should be 70% more than current food production levels. In the UK, food chain is responsible for around 18% of final energy use and 20% of GHG emissions. Estimates indicate that energy savings of the order of 50% are achievable in food chains by appropriate technology changes in food production, processing, packaging, transportation, and consumption.

ATTMA, the Air Tightness Testing & Measurement Association has introduced mandatory lodgement for all members, representing over 140 companies and over 350 test engineers across the UK. This presentation will give an oversight as to how we have made lodgement mandatory, the software we are using and finally some statistical analyses showing where the UK is at the moment with average Air Permeability (AP50) results.

If indoor radon levels are to be significantly reduced across Europe it is essential to ensure that allnew buildings built in areas affected by radon are protected against radon.In the United Kingdom the Building Research Establishment Ltd (BRE) have been carrying outresearch on behalf of the Department of the Environment, Transport and the Regions (DETR) todevelop protective measures for use in new buildings. This work commenced in the mid-1980sand has resulted in the development of a range of practical cost-effective techniques for providingradon protection in new UK buildings.

This paper discusses the use of trickle ventilators in the design for natural ventilation in dwellings. The discussion is based around the results of a field monitoring experiment where 17 out of 32 houses were fitted with trickle ventilators as a remedial measure to improve the distribution of ventilation and to reduce the occurrence of condensation. Reductions in condensation, effects on energy use, window opening and occupants views are considered. The paper concludes that trickle ventilators are a successful component part in the design of natural ventilation systems in dwellings.
