R&D, Sustainability & Innovation

All great architecture must be, by definition, sustainable.


RWA carry out all their work from an R&D approach, exploring design solutions to face the ever-changing challenges imposed by the market.

One of the essential factors of Architecture is, undoubtedly, sustainability, meaning that which seeks minimising and, ultimately, neutralising the negative impact that buildings and the construction industry have on the environment.

Tradition & sustainable architecture

Vernacular architecture has historically incorporated technical and constructive solutions that adapted the needs of the building to its immediate environment. These solutions allowed making the constructions more sustainable in the most elementary sense of the concept. The use of eaves for protection from rain, the correct orientation of the openings, cross ventilation, patios and chimneys to take advantage of the Venturi effect, Trombe walls, the use of vegetation to create climatic microenvironments, lattices for solar protection, the use of autochthonous materials, etc., are strategies that were developed on a small scale and that continue to be fully valid as current solutions for architectural sustainability.

Innovation & sustainability

New technological solutions - such as the use of renewable energies -, political and social approaches - such as aid programs to improve energy efficiency - and green certifications - such as Passivhaus, LEED or BREAAM - have promoted, in recent years, a change in mentality that RWA have been betting on since the beginning of our professional career.

Industrialised construction

Industrialised or prefabricated construction is another way to implement or improve sustainability in our buildings. Not only because it allows us to optimise the quality of execution and construction times, but also because it facilitates the choice of more sustainable materials, the monitoring of their certification, the reduction of errors and the consequent energy savings in the repetition of finished works. To these benefits we must add the decongestion that the construction works produce in urban areas in terms of air and noise pollution, in addition to the reduction of traffic associated with shorter execution times. Nor is negligible the minimisation of the risks of accidents at work and the incentive to create jobs for specialised labour, which results in economic and employment improvements for society as a whole.
In short, industrialisation affects different fields: training of people, technical investments, implementation and continuous improvement of construction processes. 


RWA approach all their projects from the conceptualization and design to obtain energy qualifications such as LEED, BREEAM, etc. These certifications evaluate the energy efficiency of the buildings but, at the same time, value other aspects inherent to the building such as its sustainability, useful life, atmospheric impact, the use of water, materials and resources used, and, also, the quality of the resulting indoor environment and the design process.

RWA have always been at the forefront of sustainability in architecture, in projects such as the office building on Calle Pedro de Valdivia 10 - First building completed in Spain with LEED certification in 1999 -, the Augusta Business Park - Endesa Award for the most sustainable non-residential building 2008 - the Castellana 79 building - LEED Gold 2009 certification - or the Mirasierra building - Leed Silver 2009 Certification.

The strategy to be adopted for each case is established by making a previous evaluation of the building's needs, the possibilities of our clients and/or the characteristics of the projects, as for example in:

  • Existing buildings - replacing energy systems with more efficient and environmentally friendly ones, integrating renewable energies; Improving insulation; Optimising the use of natural light and building orientation.
  • New buildings - achieving the goal of "Nearly Zero Energy Consumption Building".

At RWA we stay up-to-date on the use of the latest leading-edge technologies. That is why, besides using CAD design tools (Computer-Aided Design), we have been working for years using BIM (Building Information Modeling) and Real-Time Rendering technologies. Our professionals, with extensive international experience, are trained in the use of these technologies that allow us to minimise errors in projects, coordinate with other agents in the sector, ease the monitoring of the work and facility management, and even help our clients to a better understanding of our designs with the help of 3D immersion.



All these efforts by RWA in regards to developing an innovative and environmentally conscious architecture have been combined with research work in other equally fundamental parallel aspects of architecture. Studies carried out in the field of collaborative offices, technological development or changes in rental housing have been published and discussed in various media and conferences.

From RWA we endeavor to contribute our ideas and research to the different agents in the real estate market, so we try to participate in as many technical conferences and seminars on these topics at national and international level.

Here are some of our research and dissemination works:

The Digital Transformation

The workplaces are the spatial support of the digital transformation.
These are acquiring new characteristics, being part of the transformation of the way work is developed.
The physical space is complementary to the digital space.
Objectives: to define the physical space according to the organisation and the particular operations of the company and to be a means of communication and spatial experience of the brand.

Built To Rent - The project defines the product

In the housing rental market, a change is in process, leaving behind the undifferentiated housing, to which the tenant adapts, and moves towards precise typologies in which multiple factors are contemplated to satisfy more specific demands.

We move from container buildings for rental units, in which the spaces and services offered have become increasingly important, to focus on tenants and their specific demands.

The architecture project is one of the substantial instruments to outline these specific models. The promotion of housing or rental accommodation does not respond to a single model. The definition of the appropriate model has to focus on the tenants and their specific demands. The definition of architecture helps to characterize the offer.
