Frequently Asked Questions

Find answers to the most common questions about energy labels, sustainability measures, and property efficiency improvements.

1. What is an energy label for homes and non-residential buildings?

An energy label is an energy performance indicator for homes and non-residential buildings. It shows how energy-efficient a building is and is issued based on calculations and measurements. The label has several classes, from A to G, where A is the most energy-efficient. You can check a label by address or learn more on our services page.

2. Why is it important to have an energy label?

An energy label is important because it shows how energy-efficient a building is. This makes it easier to determine which sustainability measures are needed to improve the label. In addition, it is mandatory to offer an energy label when selling or renting out a home or non-residential building. Request an inspection if you need a certified label.

3. How is the energy label determined?

The energy label is determined based on calculations and measurements of, among other things, the insulation, heating, ventilation, and lighting of a building. The label is established by an expert recognized by the national government. Read more about the process on our energy label page or about Hasibo.

4. Can the energy label be improved?

Yes, the energy label can be improved by taking sustainability measures such as adding insulation to walls, floors, or the roof, installing double or triple glazing, upgrading to a more efficient heating system like a heat pump, adding solar panels, or improving ventilation systems. Each of these upgrades contributes to a better energy score. Ask Hasibo for tailored sustainability advice.

5. When do I need an energy label?

Every home in the Netherlands, whether for sale or rent, needs an energy label. You need an energy label at key moments such as sale, rental, and delivery of a home or property. Start with a quick label lookup or book an assessment.

6. Does the energy label affect my home's value?

Yes, a better energy label can positively affect the sale or rental value of a home. It makes the property more attractive to buyers and tenants. Improving performance is easier with clear home energy services from Hasibo.
