Energy labelling and energy performance certificates are not just legal requirements – they are also tools that can contribute to significant cost savings and increased building value. In this comprehensive guide, we take you through everything you need to know about energy labelling for commercial buildings and housing companies in 2025.
Energy labelling is a standardised assessment of a building's energy performance and efficiency. An energy performance certificate consists of two main components: the energy performance rating (AG) which shows the building's energy efficiency, and the heating rating which indicates how environmentally friendly the heating system is. This gives owners, tenants and potential buyers valuable insight into the building's energy performance.
All commercial buildings with more than 1000 m² of heated usable area must have an energy certificate. For commercial buildings in general, the requirement for energy labelling applies to sales, rentals and new construction. In the event of a lack of energy labelling, NVE has the authority to impose a fine. Since the energy certificate is required by law, the lack of one can affect the building's marketability and rental value.
For commercial buildings, energy labelling is particularly important for several reasons:
Housing companies have their own challenges and opportunities:
The process typically goes like this:
The costs of energy labelling vary based on:
Typical savings may include:
A good energy rating is more than just a legal requirement – it is a tool to reduce costs and environmental impact. With the right expertise, the process can be simple and add value to your property.
Everything you need to know about energy labelling and energy certificates.
The energy certificate is valid for 10 years, but must be updated if there are major changes to the building or its technical systems.
For commercial buildings and larger housing companies, expert expertise is required. Energihuset has certified energy advisors who can perform the labeling.
