Greenpeace Spain Headquarters won the Sustainable Renovation Grand Prize of the 2019 Green Solutions Awards at the Spain level + the international Sustainable Renovation Grand Prize.
The project consists in the rehabilitation of a 1000 m2 office space to be the new headquarters of Greenpeace Spain. One of the fundamental values of Greenpeace is the action and the project seeks to represent it through a sustainable architecture, which takes care of people and the planet.
We represent the action through the banner and other elements that reflect the soul of the organization. We recycle these elements to create luminaires, curtains or the ceiling itself. The distribution of the space has been based fundamentally on the maximum use of the areas with natural lighting to house the work area and the division of the space in public zone/ action zone and private / production area.
Very demanding ecological measures have been taken such as the isolation of the entire interior envelope to improve its energy efficiency, guaranteeing a minimum energy expenditure. Low impact ecological materials have been used taking its LIFE CYCLE ANALYSIS into consideration: recycled, recyclable and organic (recycled cotton insulation, wood fibre, natural cork, plant-based paints, ecological varnishes and wood with FSC sustainable management certification, etc. ).
For cooling, an evaporative system has been designed avoiding the classic air conditioning systems that use chlorofluorinated gases with a high degree of impact on climate change. This system has an energy expenditure 80% lower than a conventional system and generates better air quality when filtered. The ventilation is mechanically controlled double flow with heat recovery. Controlled mechanical ventilation is the most effective way to combat the accumulation of biological, chemical and radioactive contaminants, and the double flow with heat recovery avoids the energy losses of traditional systems.
The lighting is led at all points of light and with a chromatic reproduction of 90% guaranteeing the best lighting quality with the lowest energy expenditure. A planter design has been used to introduce vegetation on the roof in order to generate a feeling of approach to nature and achieve an improvement in the visual and acoustic comfort of the space. We use a ceramic filter to obtain water free of odours, pathogens and other substances and thus obtain a good quality of water for consumption. The quality of the light, the materials used, and the systems of installations have been chosen taking into account the HEALTH and COMFORT of the people.
Finally, the ACV ECOMETER tool has been used to calculate the life cycle analysis of the project and we have obtained a carbon footprint impact of 124 tons of CO2 throughout the construction process, which means a very low impact (124 kg / m2), due to the low environmental cost of the chosen materials and the austerity and simplicity of the space. The 124 tn of the work has been compensated by sAtt with a compensation program in Nicaragua. As the building operates with 100% renewable energy and has no combustion element, we can affirm that it is a zero CO2 project, since it has offset its environmental cost in terms of carbon and in its use it will not emit any gram of CO2. With this, Greenpeace ensures that their office participates in an idea of decarbonising the buildings being their own headquarters consistent with their values.

Mission and vision
Greenpeace is an independent organization, politically and economically, that uses nonviolent direct action to attract public attention to global environmental problems and promote the necessary solutions for a sustainable and peaceful future.
The fight against climate change and energy policy are one of the main objectives for which the organization works. Greenpeace calls for ambitious commitments in the fight against climate change: emission reduction, energy-saving measures and support to renewable energy.
In this context, Greenpeace works and researches for the development of sustainable cities. The cities, play a fundamental role in the fight against climate change and are also considered the cathedrals of consumption, but also the places where the change towards a more sustainable planet will take shape. The city is an insatiable consumer, but the scarcity of natural resources will be its fundamental limiter. To change this situation, we have to change our way of life, including consumption, mobility and construction.
Greenpeace works to achieve the progressive elimination of organochlorines, used in the manufacture of PVC plastic. The production of these compounds releases persistent, bioaccumulative and toxic substances for the environment and health. Therefore, the use of PVC-free materials in the project has been a premise.
Another of the starting premises is to propose an air conditioning system that is most respectful with the environment, free of any chlorofluorinated refrigerant. A solution based on indirect evaporative equipment (with the support of direct equipment) is proposed, which uses water evaporation to reduce the air temperature, without increasing the absolute humidity. The thermal efficiency of the evaporative systems is extraordinary since its electrical consumption is that corresponding to the fans of the equipment. It is estimated that the air conditioning of 1,000 m2 will require an installed electrical power of less than 10 kW.
An architecture has been developed that represents the client's values, respectful of the environment and the health of the people who are supported by these measures:

Indoor Air quality
DOUBLE-FLOW CONTROLLED MECHANICAL VENTILATION
The double-flow controlled mechanical ventilation system (with heat recovery) has filtration units that clean the air of particles, guaranteeing the quality of the indoor air.
The ventilation equipment with heat recovery supplies the room with fresh filtered fresh air with a sufficient flow rate and proportionally adjustable. At the same time, they aspirate an equivalent volume of stale air, loaded with CO2, and eliminate it as evacuated air. This also effectively eliminates other harmful substances, such as odours, fine powders, moisture, etc. Heat recovery takes place by means of a corrosion-resistant rotary heat recuperator with heat recovery factors of up to 90% and moisture recovery factors of up to 90%. In this way, the primary energy costs of the heating installation are considerably reduced. The FSP (fan specific performance) value also reflects the high degree of energy efficiency. Ventilation equipment model with heat recovery: Wolf CRL 4800 iH. RWT rotary recuperator.
Health & Comfort
GEO-ENVIRONMENTAL HEALTH ANALYSIS
A study has been conducted aimed at identifying the different risk factors present in the premises, factors of geophysical, physical, chemical and biological origin. Geoenvironmental analysis is a tool for disease prevention. After the analysis, the corrective measures are indicated for the values that are above what is considered acceptable according to the norm FSG 2015 V.1.
The main environmental exposure factors are:
Low-frequency alternate electric fields.
Low-frequency alternate magnetic fields.
Harmonics in the installation
High-frequency artificial electromagnetic radiation.
Continuous or electrostatic electric fields
Continuous magnetic or magnetostatic fields
Environmental radioactivity, especially radon gas.
The geophysical activity of the terrain: magnetic field and terrestrial radiation.
Aldehyde levels and especially formaldehyde.
VOC levels (Volatile Organic Compounds).
The levels of particulate matter.
Nitrogen dioxide gas levels
Sulfur dioxide levels.
The levels of carbon dioxide.
For electromagnetic contamination, ground connections have been put in place. They protect in case of discharge and contribute to reducing the electric fields generated by the different devices we connect to the network. Due to an electric field value above the reference in the workplaces, a blocking measure is implemented by means of aluminium wiring trays or other conductive metal under the tables, with grounding.
- Finishing work / flooring
Natural cork floor
We replace the existing PVC flooring with another one with good environmental performance. A floating cork floor is chosen in two different touches. Cork is a completely natural material, with a transformation process with very low impact and close origin (Portugal).
All the materials used have been chosen with the objective that the impact derived from their life cycle analysis is as small as possible. Recycled, recyclable, and renewable materials predominate taking into account the traceability and proximity to the project so that the carbon footprint derived from its transportation to the worksite is as low as possible. The measurement and calculation of the carbon footprint have been made using the ECOMETER ACV tool.
- Finishing work / Partitions, insulation
Recycled cotton fiber insulation
Insulation based on regenerated textile waste, which constitutes up to 85% of the product's composition. Not only do they not only consume resources but they contribute to eliminating waste from other industrial processes to incorporate them into the architecture, promoting the circular economy.
It has a low CARBON FOOTPRINT, contributing to minimize global warming and reduce waste from the textile industry. NO TOXICITY throughout its useful life and not irritating.

ENERGÍA 100% RENOVABLE
La oficina utiliza energía 100% renovable de origen propio a través de un molino eólico instalado en Cataluña. De esta forma conseguimos la descarbonización del local en su uso e impulsamos el cambio de cambio de modelo energético.
Hemos calculado a través de la herramienta ECÓMETRO ACV la huella de carbono del proceso de ejecución, fabricación de los materiales y transporte a obra, con un resultado de 124 Tn de CO2. Durante su uso, esta sede no emite CO2 ya que está 100% electrificada y con 100% energías renovables. sAtt ha compensado la Huella de Carbono (124Tn) en la construcción con un programa ECODES de reforestación en Nicaragua.
EFICIENCIA ENERGÉTICA Y MEDIDAS PASIVAS
La estrategia energética es reducir al máximo la demanda a través de medidas pasivas. Para ello se ha aislado la envolvente (paredes, suelos y techos), se han instalados vidrios con altas prestaciones y se han puesto elementos de control solar. De esta forma conseguimos ahorrar energía y reducir el impacto.
SISTEMA DE REFRIGERACIÓN LIBRE DE GASES FLUORADOS
Para mantener una buena temperatura en la oficina utilizamos un sistema evaporativo directo e indirecto que no usa gases fluorados, genera mejor calidad del aire y supone un ahorro del 80% frente a un sistema convencional con bomba de calor.
