Single-family dwelling between party walls in Vilanova i la Geltrú

This is a high energy-efficient single-family dwelling between party walls in Vilanova I la Geltrù developed according the Passivhaus standards (pending Passivhaus Plus certification) in order to achieve a passive house with nearly-zero energy use and great interior comfort.

The Plot

The town is 22m above sea level while the plot is 30m above sea level. It has an irregular shape and is 2% inclined. It is on the street level with existing adjacent party walls. The main road to the plot is a 6m-wide one-way road, with low traffic volume and low noise level.

The Project

The plan is a building between party walls and façades to the main road and to the inner courtyard. The construction is detached to the party walls of the adjacent buildings, both to the northeast and to the southeast. It consists of a ground floor and first floor with a transitable terrace. The parking space is on the ground floor, outdoors. The ground floor accommodates the accesses, the parking space and the dwelling’s day zone, while the first floor includes the night zone.
The unbuilt plot area is allocated for a garden and a swimming-pool to be used exclusively by the dwelling. Vertical communication is achieved through a vertical core made up with the stairway connecting the different floors.

The Construction

The structure of the dwelling provides continuity to the neighbouring façades and plays with three main materials depending on the use, position and indoor needs: a continuous coating, Wood and natural stone coated walls. Despite not featuring the same materials or constructive solutions of the adjacent buildings, the materials follow the same colour range and align with the surroundings. ETICS and a next-generation continuous coating finish is used for the vertical plane predominant part. This is a white reflective, dirt-resistant finish featuring a decontaminating effect based on organic pigments and synthetic resins.

The Functional Programme

The functional programme of the dwelling includes five people. It consists of a dining-living-kitchen area with space for a laundry area. It features a double bedroom, two single bedrooms, a study and three full bathrooms. Both the vehicle and walk-in accesses to the dwelling are on the ground floor.

Energy Efficiency

The SgJoaquim dwelling is pending Passivhaus Plus certification. In order to meet such certification’s requirements, the Passivhaus Classic certification relevant requirements (airtightness, lack of thermal bridges, significant insulation, heat recovery system and high-performance windows) are met along with a maximum renewable primary (PER) energy demand and photovoltaic generation. Thus, high interior comfort and extremely low energy demand are ensured.
