We design strategies and solutions for healthy buildings.

We spend more than 90% of our time indoors.


Indoor Environmental Quality (IEQ) encompasses the conditions inside a building (air quality, lighting, thermal conditions and ergonomics) and their effects on occupants or residents. Strategies and solutions for enhancing IEQ seek to protect human health and to improve people’s quality of life and well-being. In addition, other benefits, derived from these improvements, can be gained, such as increased productivity at work, enhanced learning in teaching environments and the increased value of the spaces and buildings concerned.

Indoor environmental quality consulting service in the design phase (new and rehabilitated buildings)


We offer a consulting service in IEQ to building design teams, to integrate strategies and solutions from the outset, which is the key time to leverage the utmost potential and optimum performance from investing in these improvements.

We apply a participatory and integrated working methodology from the very start of the process.

This methodology allows different perspectives to be borne in mind, especially that of the user, the main beneficiary of enhanced indoor environmental quality. We have the technical expertise and tools required to advise architects, building contractors, developers and local authorities as well as interior designers or other agents involved in construction, in terms of the most appropriate strategies and solutions (materials, installations, equipment, spaces, etc.) to ensure good indoor environmental quality in the newly-built or rehabilitated building.

The proposed solutions are put forward taking other criteria as relevant as energy efficiency and environmental impact into consideration.

We also offer different certification processes, since we have extensive experience in private certification consulting, including BREEAM, DGNB and LEED. Additionally, we integrate innovative building standards such as WELL, offering a comprehensive and holistic vision from the early stages to guarantee the optimum achievement of the objectives pursued.

We take care of all the administrative procedures with third parties, both in terms of regulations and matters with international bodies responsible for approving private certifications.

Indoor environmental quality consulting service in the operating phase (existing buildings)


AIGUASOL fosters the improvement of the environmental conditions inside existing buildings (during its operating phase) through the provision of comprehensive guidance on indoor environmental quality. This service ranges from the monitoring and evaluation of the main indoor pollutants to appraisal, participatory design and support in the implementation phase of the most efficient and innovative strategies to improve indoor environmental quality. Consulting can be performed in any type of building: offices, schools, hospitals, shops, industrial environments and public buildings.
