Hello, we recently purchased our plot of land and have two years until we need to start construction. Since we own a condominium, we want to take our time with the building process and plan everything carefully. A developer mentioned that it would be wise to start as soon as possible because energy efficiency regulations will become much stricter in 2016. In addition, building material costs are currently rising significantly. What do you think? Is the seller trying to pressure us without reason, or is he right? So far, we haven’t found a suitable floor plan or developer, and we still want to sell our apartment...

A KFW70 house reduces the annual primary energy demand specified in the 2009 Energy Saving Ordinance by 30%! Compared to the reference house; the reference house is set at 100%!

Energy Saving Ordinance 2014 effective from 01.01.2016:
• Reduce the annual primary energy demand by an average of 25%!
• Improve the thermal transmittance (U-value) by an average of 20%! From the 2016 Energy Saving Ordinance onwards, for example, a current KFW70 efficiency house must reduce the annual primary energy demand by an average of 25% and improve the thermal transmittance (U-value) by an average of 20%.
That makes sense! It certainly won't get cheaper; I would doubt it being cost-neutral anyway.

You’ll have to explain this calculation to me, please.
Regards, Bauexperte Then why are you asking if you already know better?

It could have been that I misunderstood something or simply missed it.

For the current efficiency house 70 standard, the transmission heat loss (H’T) must be reduced by only 15%, but from 2016 onwards, for houses under the Energy Saving Ordinance, it must be reduced by 20%. Whether you make up the missing 5% through walls, roof, or windows doesn’t matter; it counts for the entire building. But something has to be done...
So there is at least this small change, and then it is no longer a subsidized efficiency house but simply complies with the Energy Saving Ordinance. Whether the subsidized loan at the current interest rate (10 years) makes a difference for you is something you need to decide yourself. However, if you plan to build at the beginning of 2016 and all the requirements are already met in 2015, I would also submit my building permit / planning permission application in 2015; anything else is a waste of money.
