Gebäudeenergieanalyse

Gebäudeenergieanalyse, also known as building energy analysis or building energy assessment, is a process used to evaluate the energy performance of a building. This analysis aims to understand how a building consumes energy, identify areas of inefficiency, and propose strategies for improvement. It typically involves collecting data on the building's construction, systems, and occupancy patterns.

Key aspects of a Gebäudeenergieanalyse include the assessment of the building envelope, which comprises walls, roofs, windows, and foundations, to determine heat loss or gain. The performance of heating, ventilation, and air conditioning (HVAC) systems, lighting, and other energy-consuming equipment is also examined. Occupancy schedules and internal heat gains from appliances and people are considered to create a comprehensive energy model.

The results of a Gebäudeenergieanalyse can inform decisions regarding energy efficiency upgrades, such as insulation improvements, window replacements, or HVAC system modernizations. It is also a crucial step in complying with energy performance regulations and certifications, like those required for new construction or major renovations. The ultimate goal is to reduce energy consumption, lower operational costs, and minimize environmental impact. Various software tools and methodologies are employed to conduct these analyses, providing quantitative data on energy use and the potential savings from proposed interventions.
