FloyHello everyone,
we are planning to build a 180 m² (approximately 1,940 sq ft) city villa with two full floors, without a basement.
The house will be constructed using Poroton brick in a monolithic wall structure. Underfloor heating will be installed, and a wood-burning stove is planned for the lower living area (about 65 m² (700 sq ft) including living room, dining area, and kitchen).
Location is in Hesse, Germany. A gas connection is available. The house will be occupied by two adults and one child, possibly two in the future.
What would be the most sensible energy concept for this situation? How should the windows and walls be designed in combination with the proposed energy system?
Thanks in advance for any helpful advice.
Best regards,
Floy

Hello!
If you are considering purchasing a house of this size, I strongly recommend finding an HVAC specialist or an architect with expertise in building services engineering to support you in your planning.
Here are a few suggestions and thoughts.
- Since you mentioned that a gas connection is available, a gas condensing boiler would be a good option to provide heating with minimal effort.
- In addition, since you plan to install underfloor heating, it might be worthwhile to integrate solar energy to support both the heating system and hot water production.
- Furthermore, the wood-burning stove should be connected to the hot water and heating system via a water jacket to avoid wasting energy produced.
- Regarding your question about windows and walls, a description of the floor plan and window layout or a drawing would be helpful, as further recommendations can only be made after reviewing the building’s geometry.
In general, when planning a new build, it is important to try to minimize energy consumption as long as it remains economically reasonable. However, beyond a certain point, it is more cost-effective to maintain the existing insulation standard and accept some additional operating costs.
