SUMMARY:

This research assesses the potential for achieving zero-energy buildings (ZEB) and nearly zero-energy buildings (nZEB) offices in a warm and humid climate at low latitudes, regarding the cost and energy balance between envelope energy efficiency alternatives and roof utilization for photovoltaic energy generation. The research problem originates from the obstacles of supporting design decisions to achieve ZEB and nearly ZEBs from the early design stages when decisions impacting energy performance and cost occur, and subsequent alterations are not feasible. The main difficulties are related to the quantifying energy balance methods as they require characterizing parameters that are still unknown and are defined later in the design process, as well as the lack of information regarding the economic viability and attractiveness of the most impactful design parameters. The solution to assess the energy balance concerning architectural design decisions was creating a predefined design space with the most impactful parameters and graphical resources for identifying solution spaces. The design space was generated using thermal performance simulations through the INI-C metamodel, parametric simulations of photovoltaic system performance in SAM, and auxiliary calculations in a spreadsheet. The energy balance assessment focuses on the most recurrent and feasible combinations of the building envelope and the rooftop photovoltaic system, followed by economic performance comparisons. At the qualification level, this document presents the complete method and results concerning the pre-design energy balance approach and the delineation of the solution space. The procedures have proven suitable for balancing and characterizing the most influential solution space parameters. The primary outcomes so far are every envelope level may achieve an energy balance compatible with ZEB and nZEB, and the most impactful parameters are the number of building floors, the photovoltaic performance, and the roof area usage. The most favorable design project limits ZEB buildings to 4 stories and nZEB to eight. In contrast, the least favorable limits ZEB to two stories and nZEB to four.
