This thesis examines the energy efficiency of passive techniques in office buildings, highlighting their importance in reducing energy consumption.Building energy consumption accounts for 40% of total energy use and 36% of CO₂ emissions in the European Union. For this reason, European directives and legal regulations require improvements in energy efficiency. A significant solution is the Passive House standard, which promises up to a 90% reduction in heating energy consumption and contributes to improving occupants’ quality of life. To date, thousands of buildings worldwide have been constructed following this standard.In this study, an existing office building at the Technical University of Crete was modeled as a Passive House using the PHPP software. The process included thermal insulation and airtightness improvements, window frame replacement, and the addition of a ventilation system. Furthermore, energy consumption was reduced by upgrading the heating system and electromechanical equipment, as well as installing an electric water heater and photovoltaic panels.This thesis confirms the significance of passive techniques as a means of enhancing energy efficiency and contributing to sustainable development.
