ᐅ Designing a Living Room Gallery with Energy Efficiency in Mind

Hello,
we are planning to build a house that will feature a gallery opening over the living room (open up to the roof, about 6-7 meters (20-23 feet) high). We designed and planned the house ourselves based on a reference project.
Now we have a question that’s troubling us:
Could heating the open living room be problematic, since warm air naturally rises?
We think we need to consider the following:
- good roof insulation
- high thermal performance of the masonry
- glazing
- air circulation (the roof must be airtight, no cold air intake from the basement or ground floor)
Additionally, we want to integrate a garage in the basement under the living area (on a slope). We plan to insulate the garage ceiling accordingly but still fear there could be additional heat loss.
Planned heating: underfloor heating and a fireplace in the open living and dining area.
Specifically, we are wondering if we have considered everything or if there are important points we might have missed. Is this approach energy-efficient and cost-effective to implement?
We still plan to consult with an energy advisor and an architect. Since we are planning everything ourselves in advance, we would be grateful for your opinions and experiences.
Here are 2 images illustrating our design (preliminary draft without furniture, railings, etc.):

No, you can’t... A 1x1x1 meter (3x3x3 feet) cube has a surface area of 6 square meters (65 square feet). A 1x1x3 meter (3x3x10 feet) shape with the same living area has a surface area of 14 square meters (150 square feet). The heat loss here will be twice as high. A 10x10x1 meter (33x33x3 feet) shape has 100 times the living area, but with only 240 square meters (2,580 square feet) of surface area, the heat loss is only 40 times greater.
With double-glazed roof windows, you risk condensation when it’s cold.
Please get a planner who knows what they’re doing and has expertise. Philosophizing over drinks won’t make the house any cheaper.

A 1x1x1 cube has an envelope surface area of 6 m² (65 sq ft). A 1x1x3 shape with the same living area has an envelope surface area of 14 m² (151 sq ft). In this case, the heat loss will be twice as high. Addition: Heat loss through the building envelope, which should not be confused with the energy demand required for heating.

But of course, you’re right—someone with expertise in this area should be involved.
I just think it’s always good to consider such things yourself before handing them over.
That has proven to be very effective many times!

If I had to estimate, I would say around 8-10%, but in my opinion, that doesn’t matter much since you are planning a photovoltaic system.
That’s pretty much true in almost every situation.
When designing an open space inside the house, several factors need to be considered.
What is the purpose of the water storage tank if the air-to-water heat pump already serves that function, or do you mean an air-to-air heat pump?
Best regards, Bauexperte

How much higher could the monthly heating costs be due to a gallery,
or how much higher is the energy demand by 10 / 20 / 50 %?

It is also important for us to build in an energy-efficient way.
Unfortunately, it is not really possible to reconcile both goals.

When designing an open space inside the house, several factors need to be considered.
- the open space “wastes” usable floor area
- building an open space involves additional structural effort
- the open space must be ventilated, so ideally with an electric window opener
- clarify who will clean the window in the future
- noise issues
- odor issues, especially with an open kitchen

For heating, we are currently planning an air-source heat pump,
powered by a photovoltaic system with an energy storage unit.
In winter, as support, a wood stove with a water heat storage tank.

Schluffi081525 Oct 2016 10:33That is a good question.
I am not 100% sure about it either. It depends on the additional costs of an air-to-water heat pump. With this, you can use the self-generated energy more efficiently (keyword – seasonal performance factor).

Schluffi081525 Oct 2016 10:54Oh, sorry! I misunderstood the question.
We want a wood stove anyway. So I thought it might make sense to integrate it into the heating system.
I still need to analyze the cost-benefit more closely. That was just an initial idea...
