and efficiency of the performance of enterprises, which as Fil, in Parque das Nações, Valorsul' Solid Waste Management Central at St. João da Talha, Transtejo's Fluvial Terminal of Montijo at Seixalinho Wharf and Infineon Technologies Plant in Vila do Conde, became good references.

But today the stakes are even more ambitious: a collaboration, which I have been keeping with the Instituto Superior Técnico, and the latest technical partnerships in which I am involved with various engineering firms, have been forming studies and projects where the interaction of integrated passive and active systems contribute effectively to the setting of space constructed with flagrant reductions in costs of both installation and maintenance, and thereby contributing to a relevant use of alternative energy products in the burning of fossil fuels. Something unconventional that systematizes the broadest sense of skill and art in the vast intervention process, from the territory to the object.

In this context lies the recent participation in the Programme for the Modernization of Portuguese High School Schools, from Parque Escolar, and projects on residential, services, trade and tourism classes, which to the quality of the natural environment, have been adding unique and specific values through providing a offer of innovative products such as the California's Sea in Sesimbra, Praia da Marinha in Lagoa, Quinta dos Carvalhos in St. João dos Montes, the Green Park at Sacavem, the Morgado Lusitano at Povoa de Santa Iria, Povoa's Trasnport Interface by the Povoa de Santa Iria Wharf and the Quinta da Barrada settling (New Alcobaça) at Alcobaça.

Paying particular attention to the programmatic interpretation and affecting the research for the benefit of trends and potential inherent traits of each study and each context, the experience I acquired over four decades of professional activity offers confirmed knowledge, revaluated when face to face with innovation and weighting of solutions which result from a well informed and matured projectual exercise.
