Worlds most sustainable office complex?

  • The Selvamar office campus, developed and built by ACCIONA, in partnership with Tristan Capital Partners, has achieved the “LEED® v4 for Building Design and Construction: Core and Shell Development” sustainability certification, at the Platinum level, with a score of 92 points out of 110, the highest in an international list of more than 5,000 properties.

LEED® is the sustainable building certification standard granted by the US Green Building Council (USGBC). It is currently the global benchmark.

The office complex, located in Barcelona’s 22@ innovation business district, consists of four buildings and common areas, with a floor area of more than 30,000m², and 432 parking spaces. The approximately 8,500m² available are located in one of the buildings of the complex and are being marketed by Cushman & Wakefield, Forcadell and JLL. The building currently has a 72% occupancy rate.

This large sustainable office space embodies the vision of ACCIONA and Tristan Capital Partners, through its EPISO 5 fund, to create efficient, healthy and low-carbon spaces for talent that integrate state-of-the-art construction and technological solutions. The property’s other ESG criteria include its positive impact for urban spaces’ revitalization and its contribution to the corporate governance policies of the companies that occupy the offices.

Selvamar Business Campus was designed by the architecture firm CTS Arquitectos and built by ACCIONA’s construction division. PGI Engineering & Consulting was contracted for the facility engineering, and PGI Energy & Sustainability was contracted to carry out the LEED and WELL certifications.

Energy Savings 

The Selvamar complex consists of several buildings that have connected outdoor spaces between them, with a total of 30% of the plot being landscaped. The selected vegetation is native or adapted to the Mediterranean climate, with floral species that provide habitats for small pollinators, contributing to the preservation of biodiversity.

Selvamar allows a 51% reduction in indoor water consumption compared to equivalent buildings, and a 100% reduction in water consumption for irrigation. Savings are achieved through reuse (of graywater), in addition to the use of faucets and toilets of low water consumption.

The complex provides energy savings of 34.8% compared to the ASHRAE 90.1-2010 benchmark.

The façades have been designed to minimize energy demand, combining selective glass surfaces and solar protection elements. The air conditioning and ventilation equipment is highly efficient and there is LED lighting.

The office complex has a photovoltaic solar system. It has 852 solar panels on the rooftops, with a total power capacity of 315.24 kWp, which contribute 18% of the building’s total annual renewable energy consumption. In addition, it has a 90% useful surface, with natural light and unobstructed sightlines.

The complex has optimized indoor air quality thanks to ventilation regulated by CO2 sensors, the use of low-emission materials and products, and the protection of building entrances.

The construction process and the use of materials have been designed according to the most rigorous sustainability criteria. FSC-certified wood from sustainably managed forests has been used. Of the total waste it produced, 90% has been recycled.

Green Building Africa promotes the need for net carbon zero buildings and cities in Africa. We are fiercely independent and encourage outlying thinkers to contribute to the #netcarbonzero movement. Climate change is upon us and now is the time to react in a more diverse and broader approach to sustainability in the built environment. We challenge architects, property developers, urban planners, renewable energy professionals and green building specialists. We also challenge the funding houses and regulators and the role they play in facilitating investment into green projects. Lastly, we explore and investigate new technology and real-time data to speed up the journey in realising a net carbon zero environment for our children.
