Green Certificate 4 sheets for the Joan Miró Cleaning Centre

The Joan Miró Cleaning Centre is an urban infrastructure located under the Parc de l'Escorxador in Barcelona, designed to centralise the cleaning operations of the Eixample and Sant Antoni neighbourhoods. The building, half-buried and practically invisible from the park, houses the operational facilities for around 300 workers and a fleet of electric vehicles, from where the urban cleaning tasks are coordinated on a daily basis.

The project was conceived as a highly efficient municipal facility that minimises its urban and environmental impact by integrating energy efficiency, water management and electric mobilitysolutions. Thanks to these strategies, the building obtained the VERDE 4-leaf certification from the Green Building Council Spain.

Outstanding sustainable strategies

• Electric mobility for urban cleaning: the facility operates a fleet of 100% electric cleaning vehicles, which reduce pollutant emissions during daily operations.
• Water reuse and recycling: the building uses recovered groundwater and greywater for vehicle cleaning and urban operations, optimising the consumption of water resources.
• Geothermal energy production: the air-conditioning system and domestic hot water are produced by geothermal energy, reducing the building's energy consumption.
• Infrastructure prepared for solar energy: the roof is designed to integrate a photovoltaic pergola, which will generate renewable energy for charging electric vehicles.
• Comfort and indoor environmental quality measures: the project incorporates efficient lighting, indoor air quality control and acoustic comfort strategies to improve the well-being of workers.
