Objetivos de desarrollo sostenible

Strategies implemented

Purposeful analysis of bioclimatic and environmental aspects

Objective: to conceive the building according to the criteria of circular economy

The building is located in the 22 @ Innovative District of Barcelona and is intended for applied research, in the fields of Biotech, Nanotech and new technologies, where the reduction of materials, costs and energy consumption is compatible with a positive impact both at the urban level as functional.

The building has obtained an A energy certification and a Green 4-leaf environmental certification from the Green Building Council.


The building has been designed to act as an interface or balancer between the indoor and outdoor climate conditions, like a membrane that filters and exchanges with the surrounding conditions.

Outer Layer: A horizontal slat protects and diffracts the bounced light towards the interior. A vertical mineral slat integrates with the adjoining urban space, the material is made up of photocatalytic microparticles.

Middle Layer: Ventilated chamber. Integrates all vertical lines of facilities. All facilities are registrable.

Interior Layer: A sandwich panel composed of a waterproof sheet, rock wool insulation and recycled aluminium carpentry strictly performs its function with the most suitable material, without the need for an exterior appearance.


Ecological cistern. Community living space. Rainwater store. It restores the impact of its construction with vegetation.

Rainwater catchment area: 172.80m2.

Tank capacity: 17,318m3.

Landscaped area: 172.80m2.


District Clima 22@: 90% of the air conditioning consumption is covered by the heat and cold network (99.28kWh / m2 year).

Heat recovery equipment (70-73%). Air renewal through cellular slabs.

Photovoltaic: 118 collectors. Production: 24,719.4 kWh / year. All lighting is covered.

Lighting: 83.22% of workplaces have natural lighting.


226.09 kWh / m2 year of primary energy.

107.02 kWh / m2 of final energy (99.29 kWh / m2 year air conditioning consumption. 7.75 kWh / m2 year lighting consumption). Consumption does not take into account office equipment.


50 kgCO2 / m2 year (45.63 kg CO2 / m2 year for air conditioning and 4.74 kgCO2 / m2 year for lighting)

The building has an energy remote management system.


The building is produced in the factory, assembled on-site and consequently can be dismantled and returned to nature, or as a new recycled and reused raw material.

Proximity materials: 60% of the budget

Reusable materials: 42% of the budget

Recyclable materials: 66% of the budget.

Deconstruction: 100% not including foundations.
