Germany is preparing to transform its building sector by embedding energy efficiency into every stage of construction. Under new EU regulations, buildings will soon be required to disclose their life cycle greenhouse gas emissions, shifting the focus from operational energy use to a full environmental accounting. This approach recognises that emissions from materials, construction, and end-of-life processes are just as critical as those from heating and cooling.

The study highlights that life cycle assessments (LCAs) are becoming essential tools for achieving climate targets. By evaluating both embodied and operational emissions, LCAs help identify the most carbon-intensive phases of a building’s life and offer pathways for improvement. This enables planners and developers to make informed decisions that reduce environmental impact while enhancing long-term energy performance.

Training and expertise in LCAs are expanding rapidly, driven by new funding programmes and regulatory requirements. From mid-2025, professionals involved in state-funded projects must hold LCA qualifications. This ensures that energy efficiency is not only a design goal but a measurable outcome, supported by standardised methods and reliable data.

To accelerate progress, the report calls for early regulation, harmonised standards, and simplified procedures. It also recommends integrating LCAs with digital planning tools like BIM, which can streamline data collection and reduce costs. With coordinated action, Germany can lead the way in making energy-efficient buildings the norm, not the exception.
