Hello,
I have a question about building height and energy requirements for new constructions.
Background:
1. A building permit application concerns a single-family house with a building height of 3.3 m.
2. The detailed plan allows for 3.0 m in building height.
3. The developer states as motivation for deviation from the detailed plan: a building height of 3.0 m makes it difficult to meet current energy requirements for new constructions.
My thought process and question:
How can this motivation that "a building height of 3.0 m makes it difficult to meet current energy requirements" hold? Shouldn't it be the other way around since a building height of 3.0 m creates a smaller space that needs to be heated compared to a building height of 3.3 m?
But of course, a building height of 3.0 m has direct effects on the interior ceiling height as 3.0 m creates a lower interior ceiling height if the same height (amount) of insulation on the roof is used as one would with the building height of 3.3 m.
Am I on the right track here, i.e., is the motivation "a building height of 3.0 m makes it harder to meet current energy requirements compared to a building height of 3.3 m" actually about the interior ceiling height and that it becomes unreasonably low if one is to meet today's energy requirements for new constructions?
Grateful for a response
