AT THE CUTTING EDGE OF SUSTAINABILITY: PLATINUM LEED

oxxeo has become a leader in sustainability in the office market in Madrid.

The project already holds Platinum LEED certification in the Core & Shell category, the highest distinction awarded by the US Green Building Council (USGBC), which is the most widely recognised international sustainability certification system. The aim is to promote buildings that are environmentally friendly, economically viable and comfortable to live in and work in

oxxeo is the first office project in the Las Tablas district to achieve this pre-certification. This distinction guarantees that the building has been designed following the most demanding criteria in terms of sustainability, seeking to respect the environment and provide maximum wellbeing and comfort to occupants.

LEED CERTIFICATION KEY ASPECTS

Obtaining Platinum LEED certification entailed rigorous analysis of different aspects of oxxeo including:


SUSTAINABLE LOCATION:

  • Existence of alternative transport solutions: availability of public transport, bicycle racks and parking spaces for efficient vehicles and recharging points for electric vehicles.
  • Habitat restoration: landscaping using plants native to the Madrid Region and that require low water consumption.
  • Maximization of open space: the lie of the land has been taken into account when deciding the way the building faces so that occupants can enjoy as much open space as possible.
  • The urban heat island effect reduction: all the parking spaces are underground to avoid too many tarmac surfaces, which retain heat. 


EFFICIENT WATER USE:

oxxeo will achieve a 45% saving in drinking water consumption with regard to a comparable building by incorporating efficient sanitary fittings and taps. In addition, the building will include a landscaping using native vegetation that requires little watering recycled rainwater and a drip irrigation system with built-in rain sensors.


ENERGY EFFICIENCY:

The building façade design, highly efficient HVAC systems and LED lighting allow for 40% savings in energy use in comparison to a conventional building with a similar use and surface area. The centralised HVAC system has built-in control system via sensors that promotes maximum comfort for occupants.

On the roof, there is a 319 m2 installation of photovoltaic panels for electricity generation, with 60kW peak installed power and a sanitary hot water production system that runs on solar energy supplied by thermal solar panels at 2033 kWh/month. Overall renewable energy production from all these strategies amounts to 80,823 kWh per year, which offsets 6.4% of the total energy consumption of the building.

Moreover, oxxeo will offset emissions from electricity consumption with “Green tags”, which certify that 35% of the energy consumed by the building over 2 years will be offset by investment in the cost of Green tags in renewable energy plants.


NATURAL LIGHTING AND ACCESS FOR VISITORS:

100% of occupants on the office floors enjoy natural light and direct external views.


QUALITY OF THE INTERIOR ATMOSPHERE:

The building has a thorough control system monitoring the quality and quantity of outside air in the spaces occupied.


SUSTAINABLE AWARENESS AND GOOD PRACTICES:

The construction of oxxeo includes the use of recycled and regional materials, as well as FSC certified wood from sustainably managed forests. It also has a designated waste management area covering 38 , permitting adequate separation and recycling.
