This building was awarded the Sustainable Construction Grand Prize of the Green Solutions Awards 2020-21, at both the national and international levels.

Winner of the Sports Buildings category of the WAF 2019 awards for its landscape integration into the urban environment, sustainability, and social commitment, and Winner of the Mapei Award for Sustainable Architecture2019, the new sports facility with indoor pool Turo de la Peira opened its doors in June 2019 in the neighborhood of Turo de la Piera, Barcelona.

The 4,430 m2 building features a unique laminated timber structure, supporting two superimposed spaces with large spans (27m), and a hydroponic cultivation plant façade. A comprehensive urban regeneration was proposed, concentrating the two facilities in a single building, in order to free up space and create a large garden. A demineralization and renaturalization operation, eliminating walls and hard surfaces and bridging the slopes with landscaped slopes that allow different adapted routes and create seating areas and children's playgrounds.

According to the results of the simulations, the optimization of the thermal envelope generates a total saving of 182,011 kWh/year, approximately 27,302 €/year. The climatic conditioning of the sports hall is carried out exclusively in a natural way. Side windows combined with 24 skylights are monitored by an intelligent automation system that works with temperature, humidity, CO2 and rain sensors.

Energy consumption

Primary energy need: 45,00 kWhpe/m2.year

Primary energy need for standard building: 260,00 kWhpe/m2.year

More information: According to the results of the simulations, the optimization of the thermal envelope generates a total saving of 182,011 kWh / a, approximately € 27,302 / a, with a weighted price of electrical energy of € 0.15 / kWh.

Renewables & systems

Heating system: Heat pump

Hot water system: Heat pump

Cooling system: Reversible heat pump

Ventilation system: Natural ventilation

Renewable systems: Solar photovoltaic

The pool heating and hot water production is produced by an efficient aerothermal system with Mitsubishi Q-Ton production equipment, using CO2 as a refrigerant. Heat pumps are partially powered by photovoltaic production. Dehumidification of the pool is carried out using a Hidros SRH3000 dehumidifier. Additionally, 2 VRV units condensed by water (with hydraulic ring) air conditioning the other spaces.

The track is ventilated naturally through 11 motorized openings on the façade and 24 domotic skylights, facilitating simple, cross, and chimney-effect ventilation. In this way, a supply of healthy air is achieved from the garden and the bioclimatic space that makes up the green façade.

Indoor and outdoor temperature sensors act on the openings to ventilate the track and maintain comfort conditions within the established range. Rain and wind sensors detect when it is necessary for the skylights and openings on the façade to close so that no water enters. During these moments, or when it is required to evacuate heat from the track and natural ventilation is not capable of doing so, the mechanical extraction fans integrated in each skylight are turned on to force air renewal.

The building has 600 m² of roof covered by photovoltaic panels, which generate 95,534 kWh per year.
