This building was awarded the Sustainable Renovation Grand Prize of the Green Solutions Awards 2020-21 at the national level; and a mention for the same category at the international level.
Triple is a coworking and events space located in the heart of Madrid that represents the concept of Triple Balance. Inside of it, organizations and activities whose vocation is to generate a positive environmental, social, as well as economic impact converge.
It was born from the rehabilitation of an old industrial building located in a courtyard. It has 538 m² distributed over three floors and the geometry of the building gives it a special character: its sloping roof-facade provides a powerful source of natural light that is distributed throughout the interior.
A series of ecological principles and design tools are applied to achieve the least possible impact on the environment where it is located and make Triple a healthy space. A space that respects the environment, offers maximum comfort and well-being to its users, and improves their productivity.
All this together with the use of ecological and proximity materials, the use of available resources to save energy, and an air monitoring system that maintains good air quality in the space, which is especially important in the context of COVID-19.
It is the first coworking building that received zero CO2 certification from the Spanish association Ecómetro.
The use of Ecómetro's LCA tool during the design and construction phase allowed us to make data-driven decisions to reduce the environmental impact from the beginning of the project. The emissions emitted have been offset through a reforestation program. The building is 100% electrified and the utility company provides renewable energies.

Owner approach of sustainability
Triple was born with the aim of bringing together triple balance companies, companies with a positive impact or in transition, under the same roof. The space also reflects these principles, which is why it is a healthy space that takes care of people and the environment.
Triple is the first space, but more are planned.

Product
Recycled cotton fiber insulation

Geopannel
http://www.geopannel.com
Insulation based on regenerated textile waste, which constitutes up to 85% of the composition of the product. Not only do they not consume hardly any resources, but they also contribute to eliminating waste from other industrial processes to incorporate them into architecture, promoting the circular economy.It has a low CARBON FOOTPRINT, helping to minimize global warming and reduce waste from the textile industry. WITHOUT TOXICITY throughout its useful life and non-irritating. Origin: Logroño (Spain).
Vegetable paint

Auro
http://auropinturas.es/
Vegetable paint is a low-emission, solvent-free aqueous emission naturally derived from organic and mineral products. It is a 100% natural product that does not present any compound derived from petroleum. The paint cans have been recycled as flower pots for the plants. Origin: Barcelona (Spain) / Germany http://auropinturas.es/productos/paredes-y-techos/pintura-natural-paredes-y-techos-no-321 /
Clay tile
Rústicos Toledo
https://www.rusticostoledo.com/es/
Natural clay tile.
FSC certified wood

Furniture and carpentry made with FSC certified wood. Birch and oak wood treated with organic oil (Naturtrend Zweihorn). Origin: Madrid (Spain) / Romania.
Construction and exploitation costs
- 580 160 €
Urban environment
The building is located in a central area of Madrid. Access is made directly from the street on the ground floor. It has all the necessary services and the Parque del Oeste at 5 minutes on foot.
The reform of the envelope has taken into account the integration into the interior of the block patio where it is located. For this reason, aesthetic solutions have been chosen from this perspective.
The place has a bike parking space that promotes sustainable mobility alternatives, both for the organization and for the neighborhood.

Building Environmental Quality
- indoor air quality and health
- works (including waste management)
- comfort (visual, olfactive, thermal)
- energy efficiency
- renewable energies
- products and materials
Reasons for participating in the competition(s)
Zero CO2
Using the LCA ECOMETER tool, a Life Cycle Analysis was developed to calculate, among other things, the carbon footprint of the project. The result was 196 tons of CO2 (364 kg/m2), which has been offset through a reforestation program. The CO2 offset, together with the complete electrification of the building and the use of 100% renewable energies, make TRIPLE a zero CO2 space.
Air quality and systems
The ventilation is double-flow controlled mechanical ventilation with heat recovery (VMC), which saves 40% compared to a conventional system. This way there is a continuous renewal with outside air filtered through filters that remove up to 80% of pollutant particles (including viruses and bacteria) and allow good indoor air quality. We control air quality through a continuous monitoring system that measures air parameters. It allows real-time control, as well as a daily history of different compounds and substances (CO2, VOCs, suspended particles, humidity, ozone, formaldehyde...)...
Energy efficiency and passive measures
The energy strategy is to reduce demand as much as possible through passive measures. To this end, the building envelope has been insulated, high-performance glass has been installed and solar control elements have been installed. In this way we manage to save energy and reduce the impact.
Healthy and proximity materials
Use of healthy and proximity materials: clay on the floor, FSC certified wood in the carpentry, vegetable paint on the walls, recycled textile insulation for the interior of the envelope.
Vegetation
Plants clean the air and generate healthier and more productive spaces, in addition to building a connection with nature that produces wellbeing.
Geoenvironmental analysis to create a healthy space
People's health depends on a series of perfectly measurable geophysical disturbances. We analyze waves, particles, gases, electric fields, light, shapes, colors and vegetation to propose measures and generate the best relationship between people and space.
