More than 700,000 m2 of projects in buildings of varied uses, reducing their environmental impact and energy costs and increasing the comfort of their users.

The Vision Framework


Some 40% of the world’s energy consumption is associated with buildings. Buildings are also responsible for over 21% of all greenhouse gas emissions. Above and beyond a country’s strategic vision, energy consumption in buildings has a local impact, with energy costs that have increased an order of magnitude faster than GDP in the past ten years and direct effects on productivity and the comfort of users.

What We Offer


We carry out projects from the concept design stage to the basic and master plans through to site management, implementation and subsequent monitoring.

We believe that energy is part and parcel of building design:

  • We propose, develop and adapt custom solutions to reduce buildings’ energy costs and emissions.
  • We strive to guarantee the comfort of users indoors, paying close attention to heating and ventilation and to lighting and visual factors.
  • We analyze measures in energy and financial terms, considering life-cycle costs and prioritizing measures with the greatest feasibility.

We conduct lighting, thermal performance and use-based energy consumption studies and assess efficient and renewable technologies.

We consider solutions adapted to the case at hand, ranging from residential buildings to large tertiary consumer structures like offices, hotels, hospitals, sports facilities, schools, shopping centers, etc., including everything from the technical development work to administrative procedures and subsidies.

How We Do It


With the experience and expertise we have gained since 1999, we are able to propose the most suitable targeted solutions to the specific project, considering the various perspectives and the economic, financial, environmental, operational and comfort optimization goals.

When conceiving a project, we work together with the architect, the design team, the customer and the users in order to integrate all their various needs. We look at buildings as a whole, as a complex entity with multiple synergies, assessing the different key variables all at once and integrating the entire process from the concept design and master plan to the building in operation.

We are specialists in the physics of buildings, using techniques and technologies that take into account the energy vector, such as material properties (inertia, insulation, durability), the most efficient and/or renewable energy production systems (geothermal energy, cogeneration, biomass, solar photovoltaic, solar thermal, high-efficiency heat pumps, etc.), and other elements impacting costs and comfort (distribution systems, comfort diffusion systems, etc.), continuously striving for the optimum balance. We use highly comprehensive tools and methodologies, not as an end but as a process.

We present different scenarios, identify main trends and provide a detailed look at the implementation of profitable measures, considering cost throughout the life cycle to achieve suitable solutions in every project.

We offer our results based on comprehensive, process-adapted documentation, ranging from customer-oriented reports and administrative documentation to models with detailed information on energy investments.

Featured Projects


Aiguasol and LEITAT lead the environmental diagnosis for the sustainability of BIMSA projects

Committed to reinforcing sustainability in its projects, Barcelona d’Infraestructures Municipals (BIMSA) has commissioned AIGUASOL, in collaboration with LEITAT Technological Centre, to conduct an environmental diagnosis to improve the monitoring and integration of sustainable criteria in its works and projects.

B4heatIT: Intelligence and efficiency for the climate control of the future

At Aiguasol, we are committed to energy innovation with B4heatIT, a project awarded the Green 2024 Grants from ACCIÓ, aimed at optimizing the management of heat pumps through a predictive control system. The goal is to develop and validate this technology at Bloc4BCN - Espai Cooperatiu, a leading example of cooperativism in Barcelona, to enhance its energy efficiency and reduce operational costs.

Centre Cívic de Cunit: a benchmark rehabilitation in sustainability

At Aiguasol, we conducted a study to evaluate the bioclimatic performance of the Centre Cívic de Cunit, commissioned by ROA Arquitectura, with the goal of creating a Nearly Zero Energy Building (NZEB).
