NUNO LEÓNIDAS - Arquitectos Associados, funded on 1980 in Lisbon, has completed more than four hundred projects and established a reputation as a highly professional and capable practice. The firm is very successful in public competitions and has built up a high level of expertise in hotels and tourist resorts, offices, corporate projects and residential developments.

Great emphasis is placed on advanced computer technology for administration and computer aided design. The practice has developed its own software to improve the efficiency and quality of internal methodology and project management. Normal services also include feasibility studies, project co-ordination and construction supervision with specialist areas of expertise in hotel design, town planning and passive solar architecture.

Arising from the firm's extensive experience in hotel projects, the interior design department has now been established as a separate company, NL - Decoração, Lda. Although independent, strong links are maintained with the core architectural practice in order that projects may benefit from the resultant synergy.

With the worldwide growth of BIM, NLA is stepping up to master the tools. We have a team of Architects and BIM specialists working daily to achieve more coherent projects and more sustainable buildings. There is a strategy of specific procedures and standards, which allow for better productivity and better interoperability between teams. The main BIM software is Autodesk Revit, and the LOD (Level Of Development) is between 200 and 300. We use Navisworks for the coordination of the BIM models and we are introducing the use of Civil 3D and Dynamo. The Autodesk BIM 360 DOCS Online Platform, which allows the customer to keep abreast of model developments. This cloud service allows you to control the various uploads, view and share information, keeping track of file versions. The teams work in permanent direct contact on the latest version even if in different countries.







NLA has been favouring digital solutions where the integration of Building Information Modelling (BIM) and Geographic Information Systems (GIS) is a priority. In developing our projects, the geographic context allows us to ensure a more rigorous quantitative and spatial approach in decision making, allowing for the creation of a more integrated architecture in its context, better suited to existing systems and more sustainable. Territorial management instruments particularly benefit from this integration, for NLA has developed Municipal Plans for Spatial Planning, Urbanization Plans or Detailed Plans based on these technologies. The use of Free and Open Source Software (FOSS) for the development of plans with the implementation of geographic databases in PostgreSQL / PostGIS, combined with QGIS software and spatial analysis tools have allowed the implementation of dedicated, robust, and innovative methodologies. This allows NLA to develop spatial planning projects at several different planning levels, not only nationally but also internationally, with the necessary information for land use planning decisions.

Sustainability should not be seen as a FASHION, but an attitude present in all stages of the design process. Solar energy, natural ventilation, surrounding insulation, solar protection, are tools present in almost all of our projects. Conceiving the building as an energetic and environmental system, capable of reacting and capitalizing on available and free environmental factors. The maximization of energy efficiency, combined with good environmental behavior, will lead to a new concept of life, and to an increase in the Building's competitive advantages. The Plans, insofar as they condition the design of future buildings, constitute the first element of application of these principles. We have developed a specific methodology successfully applied in the largest sustainable Plan in Europe, The Ecocentre Masterplan, in Ispra, Italy.
