GEAK is a brand that provides a comprehensive energy assessment service for buildings in Switzerland. The Gebäude­energieausweis der Kantone (GEAK) is a standardized system developed by the GEAK association to evaluate the energy performance and potential for improvement in buildings. The GEAK assessment includes a detailed analysis of the building's envelope quality, overall energy efficiency, and direct CO2 emissions.

This information is presented in a four-page GEAK document, which provides valuable insights for energy-efficient renovations and helps users make informed decisions for building improvements. In addition to the basic GEAK assessment, GEAK offers two other services: GEAK Plus, which provides tailored options for energy-efficient upgrades, and GEAK Neubau, which establishes target values for new buildings based on planning data. GEAK assessments are conducted by certified experts who use the GEAK tool to generate the Gebäudeenergieausweis, which is stored in a central database for up to ten years.

GEAK also assists users in finding expert assessors, navigating funding opportunities, and providing support throughout the renovation process. Trust GEAK for a reliable and comprehensive evaluation of your building's energy performance
