Passive house as a logical consequence? Are there counterarguments?

So in our case, that means I do have additional investments of about 30% (€60,000) but actually have a slightly lower monthly burden thanks to the lower interest rate and the savings on incidental costs.

So we are getting the Energy Plus house for €210,000 (€1,750/m²) fixed price (Energy Saving Ordinance reference house offer would be €160,000, so about 30% less).

No idea how you get to €60,000, I had written about €40,000 additional investment.

So what is it now, €40,000, €50,000, or €60,000 additional investment?

Could it be that you have included subsidies from KFW and SAB twice in your calculation? The SAB page also lists the KFW subsidies.

So, checked! It is a comparison as I already wrote above, including full cost accounting. From the 31st year, the calculation shifts towards PH!

Prepared by the Energy Department Frankfurt with Energy Saving Ordinance Reference House 2009!

The sqm costs for a PH in this calculation: €1,914 as of 2009!

If anyone wants to read the execution, contact me. I will send it to you.

I'd be interested.

@ EveundGerd,

Hello - I don't want anything from you at all, let alone imply that your values are incorrect! I responded to the statement of the OP that "his" PH currently costs € 1,750.00/sqm by showing him his own numbers again.

You are right.

I gather that 1500€ seems very suspicious to you. Can you explain why?
Can I mention the company name or post the PH so you can take a look and tell me what you think, or only via PM?


can you please send me that from the University of Frankfurt also via PM? Thanks

I’d be interested.

Sent you a PM.

I already understood that and didn’t take it negatively. I just wanted to clarify for the general public that the prices are current.
