PROJECTS TO IMPROVE THE ENERGY EFFICIENCY OF MUNICIPAL BUILDINGS DISTRICT OF SANT MARTÍ, CITY COUNCIL OF BARCELONA
IMPROVING THE ENERGY EFFICIENCY OF THE WINDOWS OF THE BUILDING OF THE HEADQUARTERS OF THE DISTRICT OF SANT MARTÍ
The building of the headquarters of the Sant Martí district also known as “Ca la Vila” is located in the Plaza Valentí Almirall. The building is protected as a Cultural Asset of Local Interest (BCIL).
The building is located in the Plaza de Valentí Almirall and was originally built as the headquarters of the Sant Martí de Provençals Town Hall in the mid-19th century by the architect Pere Falqués. The building is almost squared, with a ground floor and two floors. The side and back facades are of simple lines, while the main facade has a monumental character. This facade is divided into two sections: the ground floor with three openings and the upper part of the first and second floors, presided over by a balcony framed by pilasters and columns.
It is chaired by a gray slate tower with a cloister corner dome surmounted by a second tower with an iron balcony and a clock.
The carpentry of the facades are black aluminum without thermal bridge break and with single glazing. The glasses are reflective on the outer face to guarantee internal privacy.
Technicians from the district’s Works and Maintenance Department propose the change of carpentry to improve the energy efficiency of the building. It is required that the windows on the ground floor are security and that all the openings remain reflective on the outside.
Different alternatives are studied, the energy balance of the openable windows and closings.

IMPROVING THE ENERGY EFFICIENCY OF LIGHTING IN THE LA FARINERA CULTURAL CENTER
The building dates from 1908 when the architect Josep Pericàs y Morros built one of the so-called “floor factories” that housed the Casa Harinera de San Jaime SA, which was producing flour until 1991. It was in 1995 when the Barcelona City Council bought it commissioning his rehabilitation to Carlos San Feliu and Josie Abascal. The architectural intervention was awarded the Bonaplata Prize a few months after its inauguration as a cultural center in May 1999.
It is a 4,800 m2 center with multiple uses: workshop rooms, youth center, offices, auditorium, exhibition rooms, etc …
The center operates very long hours and seven days a week. The energy consumption is very high.
The Sant Martí district is in charge of studying the improvement of energy efficiency in lighting, taking into account consumption and management of the equipment.
An audit of the starting situation is carried out and these measures are proposed:
• Substitution of luminaires by luminaires with LED lamps
• Installation of daylight sensors connected to the luminaires in areas near the facade
• Rationalization of ignitions
• Reprogramming of the building automation system
In addition, the new lighting will adapt the light level to current regulations, thus improving comfort, energy saving and center safety
