Passive family house

Available plot on the edge of a town in Northern Moravia, specifically shaped, flat, irregular, elongated in the S-N direction, with the southern side serving as the access road, and the northern part of the plot ending with a river terrace created in the past by the river Morávka's channel.
The initial idea was to place the building at the back of the plot in connection with the river terrace and its greenery with mature oaks. Due to the size of the plot (complicated access road and engineering networks), it was proposed to locate the building in the central part of the parcel, thus achieving a division of the plot into a front and back garden and urbanistically connect to the existing rural wooden house; the realization of a new modern building versus the construction of the original, traditional,...
The covered parking and facilities for the garden, car, and storage spaces (an indispensable part of such a conceived building) are located at the entrance to the plot.

From the very beginning, the intention is to implement the building in a passive standard, using European wooden construction technology (shape optimization, layout designed so that all living rooms are oriented with glazing to the south).
The dominant axis running longitudinally through the house divides the layout into a living area (southern) and a utility area (northern).
Given the planned development on nearby plots, the window on the western facade was abandoned, which is often quite problematic in the summer afternoons and evenings.
The covered terrace and entrance provide shading for the house; they are supplementary elements of the basic shape of the building.

The foundation slab made of exposed concrete in a system formwork is based on a compacted gravel cushion.
The exterior walls are wooden, based on oak beams. A double-stud system of "two by four," where the inner stud is load-bearing and the outer is non-load-bearing (supporting the facade system). This system defines a space for the placement of thermal insulation with a thickness of 520mm (based on mineral wool, in the original plan, straw insulation was proposed, for which the stud was prepared). The walls are mutually anchored in pairs with wooden boards visually forming ladders.
The inner studs are made of lime-sand brick laid on foam glass; the ceilings and roofs are wooden.
The roofing is made with EPDM foil technology, designed for a vegetation layer for extensive greenery.
The exterior studs are diffusively open, with a ventilated façade and roof, covered with larch boards with an exposed gap (anchored on double battens); treated with wax and oil.
The windows are wood-aluminum, euro 92mm, with insulating triple glazing with a solar factor of 63%. The threshold strips are impregnated oak, the load-bearing wooden structure is larch (dried, planed timber); all wooden structures are designed to be at least 300mm above the modified ground, with the floor finish in the interior 600mm above the modified ground.

Technology:
The central unit consists of a 400l and 150l stratified accumulation tank, instantaneous heating for domestic hot water, controlled ventilation with heat recovery, and electric air heating is provided by the Duplex EC 380 unit drawing heat from the tank, source for domestic hot water and heating: 3 flat solar panels, wood-burning stove, electric heating in the tank, RVS Siemens regulation.
