How good are ground gas protection measures on buildings?

This event will explore how hazardous ground gases, particularly methane, carbon dioxide, VOC's and radon are being dealt with in existing residential, commercial and industrial developments. It will also discuss the available retrofit protection measures and examine how to implement remedial actions cost effectively.


Background
Hazardous ground gases can cause serious problems to residential, industrial and commercial developments.  The average life of a commercial building in 30 years and a residential building is about 100 years, many do not have adequate) gas protective measures in place. Even if they have, the drive to increase energy efficiency by making buildings more ‘air tight’ and our changing climate (increased rainfall and severe weather events) can affect the effectiveness of existing gas mitigation measures. Furthermore changing ground conditions on or adjacent to the site such as rising groundwater, grouting of voids, surface paving or ground improvement/piling works may amplify the risks thereby resulting in gas protection measures being required where none were previously.

For example in 2014, NHS Lothian found that carbon dioxide exposure was the cause of ill health of some residents living in a housing estate overlying a previous underground coalmining area in Gorebridge, Midlothian.

Similarly, radon does not only affect existing development across the UK not only in the SW of England. According to the Centre for Radiation, Chemical and Environmental Hazards (CRCE), ‘radon is the single largest source of radiation exposure for people in the UK whether they are at home or at work’. It is also the second biggest cause of lung cancer in this country. 

Why attend?
This event will help you to understand:
  • the nature and risk of methane, CO2, VOC and radon and their subsequent protection measures needed for residential, commercial and industrial developments.  
  • how the effectiveness of gas protection measures could change
    - over time
    - due to external factors e.g. impact of extreme climate incidents, people putting glazing to their windows, etc.
  • the difference in retrofitting protection measures for developments with radon and/or other different types of ground  problems

The event will also provide you with opportunities to network with clients, developers, regulators, health specialists, radon and other ground gas specialists.
