MONTEDATO HOUSE
LAVERTEZZO
2000-2001
First low-energy building constructed by deltaZERO.
Maximum simplicity in the design of volumes and systems.
| TYPE | Duplex single-family house, new building. |
|---|---|
| INSPIRATION | The customer is a flight enthusiast and a parachutist. |
| THEME | The flight: the large steel wing hovers from the mountain towards the lake below. |
| OBJECTIVE | High internal comfort, minimal operating costs, brightness and flexibility. Low construction costs. All the main spaces have an open view to the south. |
| DISTRIBUTION | Accessory and distribution spaces upstream; the main spaces are in line on the two floors. |
| TECHNOLOGY | Continuous ventilation system with ground collector and heat recovery-heating by means of electric resistance embedded in the screed (chimney required by the client only for occasional gastronomic use). |
| NEW | Stainless steel roof (deltaZERO design, prototype). |
| SPECIAL | Limited budget: request by the client to assume the risk on the total costs and time of realisation (general contracting). |
The building has been equipped with large windows on the south side, which, in addition to guaranteeing an open view of the Magadino lowland below and on the Lago Maggiore, represents together with the steel roof the key element of the energy saving concept.
The hierarchy of living spaces is simple and rational and follows the design criterion that characterises the overall architecture of the building.
The distribution and service spaces are located upstream, while the living spaces open up to the view of the lake to the south with large windows.
The internal partitions have been obtained by means of double-slab plasterboard walls with a stone wool cavity, which can be moved or eliminated at any time: maximum flexibility of use and modification is guaranteed.
The glazed parts of the south facade have been set back with respect to the steel roof wing at a distance such as to ensure that the glazing is shaded during the summer period (high sun) during the hours of the greatest intensity of solar radiation to prevent overheating of the volume.
At the same time, the overhang of the roof wing has been designed in such a way as to guarantee good sunshine for the glazing during the winter period (low sun) in order to obtain the best possible contribution of passive solar energy, thus minimising the need for heating energy.
Since the northern perimeter of the built volume is hollowed out in the mountain, important benefits for the thermal stability of the building derive from this, which together with the passive contribution in winter and especially in the intermediate seasons, lead to a minimum energy requirement for heating the living volume.
The accumulation effect obtained through the insertion of the volume in the mountain and the mass of concrete of the horizontal structures including the roof, has consequently an excellent indoor climate in the summer season without the need for a cooling system.
The energy requirement for heating is so low as to make the introduction of a traditional heating system superfluous: a simple and inexpensive electric coil has therefore been inserted into the floor screed, designed to operate only in exceptional moments, in the case of particularly cold winter temperatures or prolonged periods without solar energy.
The extreme simplicity of the systems has as a consequence minimal maintenance costs.
