Like many other Cape Town architects we received this letter in the electronic mailbox the other day...What it says is that all new building work, alterations and additions included, would have to comply with these regulations which targets the amount
of electricity consumed by households for heating water, temperature regulation
and lighting...

older than 12 months must accompany the application.

SANS 204 (and thus XA) have in fact been law since November 2011 when it was signed by the Minister?
Most Architects and Technologists would have been on CPD courses since Oct 2011 to get us up to date with these far ranging "new" requirements of NBR.
Not sure what status of Local Authorities are?

Thanks Jac, that is perfectly correct. The local authorities had however allowed a grace period for projects which commenced prior to the inception of the new regulation. This period expired on the 14th of May 2012. Glad to hear you're keeping up to date.
