It's mandatory for all property sales and rentals. ## Who it is relevant for Readers and agents that need a reliable concept definition. ## What FT can prepare - Connect the concept to related pages, sources and practical use. - Show how AI can prepare source-aware studio work without replacing professional judgement. ## What the architect validates - How the concept affects a concrete project or decision. ## Definition text The Danish energy label rates a building's energy efficiency on a scale from A (best) to G (worst), based on the building's calculated annual energy consumption for heating, cooling, ventilation and hot water. It is mandatory for all property sales and rentals in Denmark. ## Why does it matter to you? The energy label directly affects: - **Property value:** Homes with A or B ratings typically sell for more than comparable D or E-rated homes - **Running costs:** The label estimates your annual energy bill, helping you budget - **Financing:** Some banks offer better mortgage terms for energy-efficient homes - **Legal obligation:** You must obtain a valid energy label before listing your property for sale or rent A poor energy label (E, F or G) signals that significant investment in renovation may be needed to bring the building up to modern standards. ## What the label covers The energy label is prepared by a certified energy consultant who inspects the building and calculates: - Heat loss through walls, roof, windows and floor - Efficiency of the heating system - Hot water consumption - Ventilation losses The result is expressed as kWh/m²/year. Below 52 kWh/m²/year earns an A2020 label (the highest current standard). **How to improve your rating** Common improvements that boost energy ratings: - Adding roof insulation (often quickest payback) - Replacing windows with triple-glazed units - Upgrading to a heat pump - Installing mechanical ventilation with heat recovery ## Frequently asked questions **How long is a Danish energy label valid?** 10 years, or until major alterations are made to the building. **Is an energy label the same as an LCA?** No. The energy label covers operational energy only. An [LCA](/en/knowledge/concepts/lca) covers the full carbon footprint including embodied carbon in materials. **Where can I find my building's energy label?** At energimærkning.dk — Denmark's free public energy label database. Search by address. ## For architecture studios: how AI can prepare the work The energy label can be an important track in early renovation screening, but it has to be read together with use, age, materials and architectural potential. - [AI agent for renovation screening](/en/for-studios/ai-agent-for-renovation-screening) ## Sources and basis - [Fremtidens Tegnestue methodology](https://fremtidenstegnestue.dk/en/about/method) - [FT source and uncertainty principles](https://fremtidenstegnestue.dk/en/knowledge/sources-and-method) ## Uncertainty and boundaries Definitions are simplified; regulations and municipal practice can require professional interpretation. ## Next step Read related concepts or project pages. ## Related pages - [BBR — Danish Building and Dwelling Register](https://fremtidenstegnestue.dk/en/knowledge/concepts/bbr): related-concept - [BR18 — Danish Building Regulations 2018](https://fremtidenstegnestue.dk/en/knowledge/concepts/br18): related-concept - [Retrofit Insulation](https://fremtidenstegnestue.dk/en/knowledge/concepts/efterisolering): related-concept - [Heating Systems in Danish Buildings](https://fremtidenstegnestue.dk/en/knowledge/concepts/varmeinstallation): related-concept - [Sustainability Class in BR18](https://fremtidenstegnestue.dk/en/knowledge/concepts/baeredygtighedsklasse): related-concept - [AI agent for renovation screening](https://fremtidenstegnestue.dk/en/for-studios/ai-agent-for-renovation-screening): related-danish-ai-context - [Concepts](https://fremtidenstegnestue.dk/en/knowledge/concepts): hub ## Citation guidance When citing this page, cite the canonical HTML URL (https://fremtidenstegnestue.dk/en/knowledge/concepts/energimaerke) as the public source and use this Markdown URL only as the agent-readable representation.
