Textual content description supplied by the architects. The undertaking arose from the mixed requests expressed by the purchasers relating to its program and the traits of the city surroundings during which the undertaking is positioned, with the added conditioning elements of being a plot between occasion partitions constructed on one aspect solely, and with a decent preliminary price range. In relation to the programmatic wants, the customers are a pair with two daughters. With this situation, and in addition including the purchasers’ demand for multi-purpose areas in the home, the required residing space is pre-dimensioned: the result’s properly beneath the utmost permitted constructed space (roughly 150 m2 required < 270 m2 doable by laws, excluding the attic).
With these premises, the undertaking proposes to retreat the inside house from the southwest occasion wall, sustaining the utmost permitted quantity and liberating up a strip that has a positive orientation and capabilities as an intermediate house able to bettering the circumstances of the inside house.
This gesture minimizes the constructed and climatized floor space to that which is strictly obligatory, reduces the price of the development work, and provides an area with differentiated traits and makes use of with (variable) consolation at a low value.
The intermediate house is solved with light-weight building (transparency, absorption, quick response), and the inside areas quantity with moist building (thermal inertia, stability, sluggish response). Nevertheless, the inside enclosures and the staircase are additionally light-weight, facilitating future modifications, unifying the spatial notion of the entire, and making the surfaces near the customers friendlier to the contact.
To extend the buildup of passively captured power by the intermediate house, it’s obligatory to include building options that present thermal inertia. For financial causes, building custom, and velocity of execution, the construction of the inside areas is resolved with mortar block masonry, the cavities of that are full of compacted earth from the excavation. This leads to a low-cost building system with excessive thermal inertia and good hygrothermal efficiency, which on the similar time reduces the manufacturing of building waste. The wall that separates the 2 areas of the home (intermediate wall) just isn’t insulated and acts as an accumulator of incident photo voltaic radiation, releasing it into the inside at evening. The thickness has been dimensioned particularly for this perform, making certain that it compensates for power losses.
The intermediate house is used to enhance the efficiency of the outside aerothermal unit, making it alternate with this house, which has a extra favorable temperature than the surface, and to hold out the air renewals of the inside house, lowering losses. Along with this technique, there are massive openings on the SE façade, cross and evening air flow, and beneficiant insulation with wooden fiber panels not solely on the façades and roof but additionally on the NE occasion wall. The one air-conditioning system in the home is a 20cm energetic concrete ground slab on the bottom ground, whose warmth is transmitted by the mass of the ground slabs (of concrete joists and vaults) and the staircase (which will be divided into sections) to the higher areas.
