SUMMARY:

This dissertation examines the importance of quantifying energy and economic
parameters to achieve energy balance targets, such as energy-positive buildings
(EPBs). These goals are part of growing international policies to reduce CO2
emissions from buildings to combat climate change. Meeting targets increases the
complexity of the design process, as the balance between energy consumed and
produced by the building depends on architectural decisions made from the beginning,
when most of the building's characteristics were not yet defined, making it impossible
to quantify performance through simulations. This research addresses this problem
and proposes a methodology based on the design space to support architectural
decisions from the early stages of the design process for positive energy buildings
(PEBs) of office type, considering both energy and economic criteria in a warm climate.
The proposed methodology developed parameterized design spaces, focusing on the
most influential variables and utilizing interactive graphical interfaces. These interfaces
combined simulations through the INI-C metamodel, the SAM program, and
complementary calculations in electronic spreadsheets. The procedures for assessing
design space and its solution fields replicated those for preparing quantitative briefings,
testing hypotheses, and selecting the most promising alternatives based on conditional
logic ("if... then..."), which were recurrent in the early stages of the process. The most
influential variables and their acceptable ranges were identified, and the
interdependencies of the design variables were discriminated. Matching EEP energy
targets depends on combinations with varying levels of specificity. The closer to the
zero-balance limit, the more critical the specificity of the combinations regarding
building form, envelope performance, and energy production potential. The economic
assessment of energy production justifies prioritizing it over building energy efficiency
because the minimum required for EEP limits the potential gains for improvement.
