New Build

The need to reduce our carbon footprint has led to changes in the building regulations which are important for the long term future of biodiversity in general. These changes have led to innovative techniques and designs of build and the development of new materials to meet these needs. 

One of the key targets is reducing energy loss. This has led to the change from ventilated roof spaces to ‘airtight’ (slow exchange of air) buildings. This can be achieved in a more standard design of house by having an ‘airtight’ envelope usually comprising a breathable membrane. It may also take the form of pre-formed super-insulated panels that are constructed off-site and then rapidly put together on-site.

All low and zero-carbon build will have no capacity for bats (and other wildlife such as swifts) to enter roofspaces. Unless positive, proactive steps are taken, there is concern that future housing stock will hold no potential for bat roosts for several species.

Practical Advice 

There are products also currently available that can be incorporated into new build to aid bat roosting potential or access to a potential roost spaces and links to these are below.

NB. We would emphasise that we are in no way recommending these products and, as far as BCT is aware, they have yet to be reported as being successful.
