Hello Forum,

Greetings to everyone; as a previously silent reader, I admire the expertise and the open, straightforward manner of those offering help.

We are Steffi, 36, Lisa, almost 11, and I (Matthias), 46, currently planning the project of a lifetime.

About the project:

We want to build a passive wooden house with roughly 120-130m² (1,290-1,400 sq ft) of living space in a bungalow style with a gable roof (shoebox shape with approximately 3m (10 ft) ceiling height).

The house will have narrow strip windows on two sides (street side/north side), while the south and east sides will be opened up with large window installations.

In the garden, we plan to build a carport/garage and a natural swimming pond with an outdoor sauna.

The facade will be wooden (likely thermo-spruce) with aluminum windows featuring a Uw value under 0.8 W/m²K.

The facade and windows will come from my employer (a large company specializing in timber construction); the planner and architect authorized to submit plans is in-house.

I am personally responsible for the windows.

All other trades will be contracted based on my employer’s recommendations (foundation slab/floors/ventilation system) and commissioned independently.

The floor plan is currently being developed and the plot is being purchased (19 x 39m (62 x 128 ft)).

My question, and here I hope for your support: what type of hot water preparation/ventilation is really sensible?

I have read about concrete core activation, air-to-air heat pumps, air-to-water heat pumps, heating coils, and heat pumps in general. Who has a passive house or experience in this field and can enlighten us before the heating or ventilation installer guides us in the “wrong” direction?

We would rather not use solar panels; I’m considering a wind turbine (the location allows for it) and sufficient clearance distances are well observed. The rotor should not be the classic 3-blade type but more like a Darrieus rotor with about 1 kW output for self-consumption.

The reason is neighborhood-friendly operation: no flickering shadows and quieter running noise.

Those are the key facts—thank you and best regards, Steffi and Matthias

An update:

Planning is in full swing, all trades have now been contacted, and the building services system is finalized.

Domestic water, ventilation, emergency heating, and active cooling all integrated in one unit.

The building permit / planning permission application and the thermal insulation certificates are currently being prepared.

Best regards, Matthias

One more update:

Today, the go-ahead was given to start building the house in calendar week 48, with the windows and doors installed at the same time.

This way, the building envelope will be closed, allowing the ventilation, plumbing, and electrical trades to begin.

At the same time, I will start work on the carport and the patio roof.

The energy performance certificate and the building permit / planning permission have just been completed as well.

Another update:

Today, the application for the KfW subsidy arrived; the annual primary energy consumption is 9.9 kWh/(m²·a) x 127 m² (1,367 ft²), which makes my heart smile!

How is your wind turbine doing? I told my girlfriend about mine and immediately said I want one too [emoji3]

Well, you couldn’t exactly call ours a passive house, but it’s not that bad either :-)

By the way, where can you find those small wind turbines?
