New Construction
- Building Type : Isolated or semi-detached house
- Construction Year : 2013
- Delivery year : 2016
- Address 1 - street : Avinguda dels Paisos Catalans, 45 08680 GIRONELLA, España
- Climate zone : [Csa] Interior Mediterranean - Mild with dry, hot summer.
- Net Floor Area : 142 m2
- Construction/refurbishment cost : 1 400 €
- Cost/m2 : 9.86 €/m2
Certifications :
-
Primary energy need :
15 kWhpe/m2.year
(Calculation method : )
During the project, 2 basic premises were pursued at all times. The first was to get a home in which most of the program was developed on the ground floor with a clear relationship with the garden and the environment. The second was to create an environmentally friendly house, designed under the Passivhaus standard, of very low energy demand and where construction processes based on dry construction are used. The implementation strategy was to generate an L-shaped building, closing with respect to neighboring buildings while opening towards the garden, taking advantage of the natural sunny and good visuals. The volumetric solution was simple, with two rectangular prisms in plan. The lower plant was generated in the form of L, and a third prism in first plant united the two previous volumes.
In order to be able to develop most of the program on the ground floor, it was decided to deplete to the maximum the occupation of the lot and to divide the program leaving all the zones of services in basement plant and to distribute the stays of the house in ground floor. In this way it was possible to simplify its use and to minimize the circulations between the different spaces.
Thus, the volume located in the inner part contains the private program (rooms and service rooms) and the other the public part as are the living room and kitchen. The two volumes are linked through the vertical communications core and a third body in the first floor containing the study.
Finally a fourth element in the shape of a pergola is responsible for tying volumetrically the whole set.
Environmental and energy efficiency aspects were taken into account, such as the use of solar radiation to cover energy demand with a clean and free source, were considered in the conception process. The design, with large eaves to the south, allows us in winter to take advantage of the heat of the sun to warm the house, in summer, on the contrary, protects us to avoid overheating it.
The materialization of the project was gesture with the clear will to achieve a sustainable construction. The use of natural materials allows us 80% of employees can be recycled.
The structural part (forged and walls), are panels of contralled CLT wood. The numerical control technology used for the structural elements allows to have a much higher control of the finished product since they are realized in workshop and later they are transported to the work to be assembled.
A good thermal envelope and exhaustive control at work to minimize energy losses, added to a heat recovery system that allows us to transfer much of the heat that transports indoor air to outdoor renovation air, makes the extra heat input is very low, thus generating a very low energy demand.

Architectural description
