In the future all buildings can be like this...

LiderA is the Portuguese acronym of Lead for the environment in search of sustainable construction, and is the designation of a Portuguese  voluntary system which aims an efficient and integrated support,for the evaluation and certification process of the built environments that seek sustainability.

Through its principles and criteria, LiderA supports the development of projects that wants to achieve sustainability and certify the demand for sustainable products in the built environment (buildings, urban areas, projects, materials and products) from the design phase to the operation phase.

The search for solutions within the scope of the LiderA system is based on an advisory process by assessors/facilitators accredited by LiderA who undertook a LiderA course and had a positive evaluation in the exam. On the other hand, the LiderA system certification is carried out by an independent verification process that assigns the LiderA class (C to A ++) according to the specific practices of the LiderA system developed by Manuel Duarte Pinheiro at the Instituto Superior Técnico, University of Lisbon.

LiderA system, since 2005 contributing to sustainability

Since its creation in 2005, the LiderA system certified more than a thousand dwellings, more than five thousand hotel beds, as well as multiple Commercial projects and other Services.

LiderA has more than three hundred and fifty designers/consultants who have completed the training and initial examination of the system. As a tool for application, LiderA has already been used in two doctoral thesis, dozens of master thesis and over a hundred academic projects.

The LiderA System:

The system was developed by Manuel Duarte Pinheiro, Ph.D. in Environmental Engineering. He is also a professor at the Department of Civil Engineering and Architecture, in Instituto Superior Técnico (Lisbon, Portugal) and the founder of IPA - Innovation and Projects in the Environment, Lda.

The system resulted from a series of scientific works about sustainability in buildings and built environments, developed from 2000 to 2005, which lead, in 2005, to its first version and to the delivery of the first certifications in 2007.

The LiderA system is intended: (1) to support the development of plans and projects seeking sustainability, (2) to evaluate its performance and position in the design, construction and operation phases, concerning the demand for sustainability, (3) to support environmental management, (4) to assign a certification by trademark through a verification by an independent evaluation and (5) to be a distinctive brand for businesses and customers who value sustainability.

LiderA - Sustainability Assessment System is a Portuguese registered brand and it is composed of construction environmental performance levels, designed from a sustainable point of view, that can be compared to different performance levels (G to A + +), which should be better than existing practices (E), in order to be recognized as good sustainable practices.

If the verified LiderA performance reaches a final assessment of sustainability labelled as class C, B, A, A + or A + +, buildings or built environments are certified with a good sustainability level.

Publications and other activities

LiderA has been carrying out, since 2005, a series of publications targeted to support the search for sustainability, opinion articles, participation in seminars, courses and organizes an annual conference since 2009.

Main available publications

As an introduction to this approach it is important to refer the book on Environment and Sustainable Construction (2, 3 MB), published in 2006 by the Portuguese Environmental Agency, from the author of the LiderA system, Manuel Duarte Pinheiro, which presents the approaches, strategies and environmental criteria used in the pursuit of a healthy built environment based on ecological principles.

This book introduces the principles of sustainable construction, with special emphasis on the built environment, suggesting a set of environmental criteria to consider in the search for sustainability in construction, including the introduction of the LiderA system.

A short presentation of the LiderA system (download) and a detailed presentation that explains the system and the criteria (download) are available for download.

The current version of the LiderA System (2.0) that can be applied at different scales, from the dwelling / building scale, to exterior spaces and to the neighbourhood scales, was introduced in LiderA 2009 Congress  on the 28th of May, 2009.
