Development of a typical indoor climate model for residential buildings in Latvia

---

Abstract

This research aims to develop a typical indoor climate model for residential buildings in Latvia, addressing the need for more accurate assessments of energy efficiency and hygrothermal performance. The study analysed data from 36 buildings across the country, comparing indoor temperatures, relative and absolute humidity with outdoor conditions and deriving simple regression models for practical application. These were compared with EN and DIN standard assumptions, revealing significant discrepancies between standardized and actual indoor conditions. The model identified a heating breakpoint at +7.86 °C, lower than reported in comparable international studies, and highlighted the importance of accounting for region-specific climatic and building characteristics. The developed model improves the reliability of building simulations and supports more precise risk evaluations in renovation planning.

Keywords: building physics, indoor climate, humidity analysis, hygrothermal simulation, residential buildings
