The Manens’ mission is to interpret and meet the Client’s needs, providing technical solutions able to combine Functionality, Safety and Comfort with the big challenge of our time: Sustainability and Energy. To attain this objective, an integrated approach to building design is essential for cost-effective solutions. The building is no longer seen as a passive container of systems and technologies, but rather as an entity in which each component has an active role in the building’s result, strengthening the integration of “architecture – services – sustainability”. This new approach requires the development of new skills and state-of-the-art software simulation tools enabling the early assessment and optimization of complex systems. Thanks to our specific skills and holistic approach, Manens is today acknowledged as a leader in the fields of Sustainability and Energy for the building sector. This continues the philosophy that, for forty years, has characterized the work of the firms merged to form Manens, for whom “designing” also means “promoting” a new culture both inside and outside the firm.
