Detached wooden home soon to be developed - Senigallia (AN)

Aspects relating to type and formalities

The building runs north-south with its entrance on the north side. The project entails the development of a rectangular building comprising two floors above ground, covered by two asymmetrical pitched roofs and is characterised on the north side by an entrance portico with pergola and a large portico to the south, with open loggia above. The ground floor rooms are for daytime use and shall comprise the hall, a large living and dining area that extends outside via the portico and onto which the kitchen/breakfast room also opens up; there is also a toilet, laundry room, technical room and garage. The first floor is instead to be used for sleeping quarters and consists of three bedrooms, two bathrooms and a study. The toilets and other service rooms have been positioned along the sides most exposed to the elements (north) or with visual introspection (west).

The building is a simple volume excavated towards the south by the portico defined by the overhanging roofing and marked to the north by the everted and longitudinal to the entrance portico; different colours have been used to highlight the play on volumes laid out over the two floors.

Bioclimatic aspects

The building has been designed according to principles of bioclimatic architecture.

It has a front that is closed to the north and large openings instead to the south, where the overhanging portico and loggia allow for automatic bioclimatic regulation of the entrance of the sun during the various seasons. To the east and west, solar control is entrusted to external Venetian sun blinds. The building openings are located in positions able to ensure maximum efficiency of longitudinal and transversal ventilation. This will enable optimal summer cooling, enabling a provision for systems for winter heating only. On the external interface, the building has a ventilated underground cavity designed to insulate the ground floor from contact with the soil, and a roof with ventilated cavity wall.  The insulating cladding guarantees that there are no thermal bridges. The use of wood and natural fibres makes for a construction that is mainly natural, ecological and well insulated, which in addition to the use of renewable energies, also guarantees a high level of environmental sustainability.

Structural aspects and thermal insulation

The foundations will be built from reinforced cement curbs and beams, with sub-foundations in lean concrete, aimed at reaching the support layer of the soil. The soil obtained from the excavation can be reused to fill the depression in the lot and connect the building level with that of the surrounding land.

The two floors above ground will be built entirely with wooden structures, in order to minimise weight and hold the foundation structures. A platform frame wooden framed structure will be used, with lamellar wood panel flooring and roofing with ventilated cavity wall and ridge. Insulation is achieved inside the structure with rock wool and outside with cladding in mechanically-fixed cementite wood fibre panels.

External finishes and pertinences

The external finish will be with plaster painted in two different colours and the Canadian tile roofing. The guttering and downpipes will be aluminium pre-coated in a light colour. Windows will be PVC. External flooring will be gres.

          The residual external area will be left as a garden, retaining most of the trees present. A hedge will requalify the fencing, supplementing the existing trees and affording acoustic and visual protection to the garden.

Thermal system, renewable energy sources, energy class

In a bid to achieve maximum energy efficiency, the building is equipped with a radiating floor heating system powered by air-water electric heat pumps. To contribute towards the energy needs using renewable energy sources, the building is equipped with a photovoltaic plant on the pitch exposed to the south-east for a total of 12 panels for an installed power of 3 KW. This plant means that 71.1% of energy needs can now be covered by renewable sources. The contribution made by the photovoltaic plant in addition to the heating plant and, above all, the major insulation of the cladding with the control of the thermal bridges, gives the building an energy performance (Epi=11.92 KWh/m2) that is less than 20% of the legal limit, thereby corresponding to class A+.
