I wrote that "East, west and north sides of each room should be within 1m0.5."

When talking about blocking sunlight in the summer, I wrote that "the east, west and north facing sides of each room should be kept to 1 m0.5 or less," but this also contributes greatly to reducing heat loss in the winter and cutting down on expensive window costs.
However, a contradiction arises if a second-floor room, such as a child's room, is placed on the north side of the house.
According to the lighting standards of the Building Standards Act, the window area must be at least 1/7 of the floor area. For a room on the north side in the center, the habitable area can only be up to 0.5m3.5 x 7 = XNUMXmXNUMX, and for a northwest corner room, the habitable area can only be up to twice the area, XNUMXmXNUMX. Even if it is legally OK, most practitioners know that rooms that are close to the legal limit are very dark and there is nothing that can be done.
The only way to solve this problem, other than adding skylights, is to enlarge the windows on the north side or on the east and west sides. So, we have no choice but to make an exception.
Therefore, it is advantageous to place rooms on the south side if possible, as this avoids the need for exceptional design. However, there are cases when you have no choice but to place them on the north side. In that case, I personally recommend that you design the roof with a ridge offset and also design upper south-facing windows in the north-facing rooms.
The second Eco-House Grand Prize winner also used this method.
