DEAP calculations are currently required in order to show compliance with Part L. Thats the whole point, and its not a good reflection on an architectural website to state ‘nobody knows anything about this topic ‘ when architects involved in residential projects should be the leading profession in it.
The revised regs are simply a tightening up of the current regs.
Currently a dwelling needs to show,by calculation, that its CDER doesnt exceed its MPCDER. These abbreviations should not be alien to an architect who is involved in domestic projects.
The new regs require the CDER to be 40% more efficient than the MPCDER.Has anyone here done a DEAP calculation as part of his/her certification of compliance on a domestic dwelling under current regs??

speak for yourself . ignorance is bliss
Think it’s going to be a big wake-up call for Architects as regards energy conservation.
Many seem to view it as just another building regulation, that is to be approximately adhered to, but not too precisely as it won’t be checked as under ‘self – regulation’, there are very few enforcement staff. For instance, under (or rather not under) part M the provision of the smaller ‘WC cubicle for smaller dwellings’ when the area of the entrance storey is more than 45 square metres.
So now there is a part L for dwellings (2007)
and a part L for non – dwellings (2005) ….Could someone maybe help me out here, the recommended u-value to be used in passive houses for a concrete ground floor is 0.15, what thickness of insulation would that require, if my calculations are correct, it should be 100mm, with a thermal resistance of 4.75, is this correct?
Donegal Sir, a passive house is a lot more than just the sum of the u values of its construction. A passive design should be achieving a figure closer to 0.1 with NO thermal bridges.
0.15 will be the required u value for floor with UFH from july onwards.
