O uso do Archicad na automatização de tabelas para checagem dos limites de aplicação do método simplificado da INI-R à partir da modelagem de uma edificação de referência

Abstract

Efficient energy use in residential buildings is crucial for reducing consumption, which accounts for 27.5% of the national internal electricity supply. Lighting and climate control are the primary contributors to this demand, and designing buildings that utilize natural lighting, heating, and cooling strategies can result in significant savings. To promote energy efficiency, Brazil has regulations such as the National Program for Electrical Energy Conservation, which, through the Inmetro Normative Instruction for Residential Buildings (INI-R), provides guidelines for obtaining the National Energy Conservation Label. However, the design process and energy performance analysis are often not integrated, with energy consumption simulations conducted late, after architectural decisions have been made. Building Information Modeling (BIM) has the potential to change this dynamic, enabling energy performance evaluations in the early stages of design, optimizing the development of sustainable solutions. This study explores the insertion of parameters and the creation of automated tables in Archicad to verify compliance with the simplified INI-R method during the design process. The analysis includes modeling a reference model and creating a template of pre-configured tables and properties. Thermal parameters were manually entered and saved in a library, while geometric parameters were automatically extracted. Angular variables were manually entered due to difficulties in creating expressions linked to the analyzed elements. The work suggests future parametric verifications of angles and a comprehensive evaluation of the INI-R. This article contributes to the automation of labeling regulations in buildings and supports design teams in exploring design alternatives.
