Scientific research has given overwhelming findings that environmental problems are a severe global
threat, requiring an immediate response. In the years to come, ecological and economic constraints
will restrain social conditions. Buildings play a fundamental role in controlling and improving both,
social and environmental quality. Countless efforts are being made to promote and implement
sustainable building design. New technologies to reduce resources consumption, low impact materials,
standards, and guidelines, and building assessment methods are being developed worldwide. It is fair
to say that despite remarkable achievements in promoting sustainable buildings, they are still behind
expectation in enhancing sustainable design. When pre-design is poor or incomplete, the effectiveness
of sustainable projects is compromised. Research shows if sustainability goals are established early in
the project, against which to assess options of achievement, the success of accomplishing a sustainable
building, increases. Nevertheless, existing sustainability assessment tools evaluate a selected option
rather than allowing for comparison of alternative solutions. Also, the need for detailed data, inexistent
at those phases, hampers its use at early design phases.
To cope with this gap, this thesis proposes a new methodology aimed at supporting early design phases
decisions towards sustainable design. It is intended to aid getting goals through a measurable and easily
understood target for the building performance instead of prescribing a particular solution.
To achieve such an ambitious goal, the work was divided into five main tasks. First, literature review
was carried out on existing international recommendations for sustainable design and its assessment,
and existing buildings sustainability assessment methods. This research aimed at identifying the stateof-
the-art of such tools and standards, highlighting their advantages and drawbacks, and setting the
basis for Early Stage Model for Sustainable Design {\textendash} EasyMode. Then, analysis of the life cycle of
buildings design was conducted. Complementing this analysis, Portuguese designers were surveyed to
comprehend their understandings on sustainability and how they consider its criteria during design.
After having the output of these two phases, it was possible to set approach and framework for the
newly developed tool: EasyMode. After having a defined framework, stage four consisted in developing
the calculation procedure of the indicators included in EasyMode. To validate the efficacy of the tool, a
fifth step was taken; the tool was applied to a case study.

EasyMode aims to support designers, through the decision-making process, at early design phases,
towards successful sustainable design. EasyMode provides guidelines and concepts regarding the three
sustainability cornerstones enabling setting early sustainable goals, making informed decisions, and
selecting design options with better performance throughout the building{\textquoteright}s lifecycle. EasyMode is
intended to be easy and practical to use, so practitioners can make quick and expedite analysis, in fact
making it accepted by them. This tool will endow designers with sustainability concepts in an easy
manner, improving their knowledge on the subject and thus, improving their projects. Also, this work
represents a step further in the scientific research in this field.
