Redefining zero carbon


‘Our proposed definition recognises off-site renewables could play a part and also gives a big boost to community-scale technologies. This would have the added benefit of enabling much needed carbon reductions in the existing stock by enabling the distribution of low- or zero-carbon heat through district networks.
The full report is available on the UK-GBC web site.

‘The solutions we are pointing to are designed to ensure energy-demand reduction always comes first and on- or near-site renewables should be the focus for meeting energy needs.

Probably a better way of meeting the requirements for residual-current protection of the 17th Edition of the IEE Wiring Regulations is to use RBCOs (residual-current circuit breakers with over-current protection) rather than RCDs (residual-current devices), which are prone to nuisance tripping.

Now we are 17

One of the biggest changes to the IEE Wiring Regulations is the requirement for residual-current protection. Colin McAhren explains the reasons behind it and how to meet it.

Redefining zero carbon

The UK Green Building Council has devised a new definition of zero carbon for building based on off-site generation. It is spelled out in its report ‘The definition of zero carbon’ produced by its zero-carbon task group chaired by Mark Clare of Barratt Developments.
