Energy Rating Calculator โ€” Savings from Energy Improvements

Denmark's energy rating system (energimรฆrkning) classifies homes from A to G based on their energy consumption. Improving your home's energy rating not only reduces your environmental footprint but also lowers your utility bills and increases the property value. This calculator shows you exactly how much you can save annually by reducing your energy consumption.

How the Calculation Works

Enter your current annual energy consumption in kWh, the expected consumption after improvements, and your electricity price per kWh. The calculator shows the annual kWh savings, the monetary savings per year and per month, and the percentage reduction in energy use. These figures help you evaluate whether an investment in better insulation, new windows or a heat pump is financially worthwhile.

Energy Improvements in Denmark

Common energy upgrades include insulating walls and roofs, replacing old windows with energy-efficient models, installing heat pumps and adding solar panels. The Danish Energy Agency (Energistyrelsen) offers guidance on which improvements give the best return. Many upgrades are also eligible for the craftsmen's tax deduction or green subsidies, further improving the payback period.

Frequently Asked Questions

Can you calculate the energy rating yourself?

You can also use the Energy Calculator to estimate your home's energy rating โ€” even if your home does not already have an energy rating. The energy rating is a kind of product declaration that tells something about the home's ability to retain heat, among other things.

What does A++ correspond to on the new scale?

The old scale that went from A++ to E has now been replaced by a new scale that goes from A to G. The labelling was introduced in the EU because all LED light sources were in class A to A++ on the old scale, making it difficult to see which light sources were better for your electricity bill than others.

How many kWh does a family of 4 use?

For a family of four, the annual consumption typically lies around 4,400-5,000 kWh.

What does energy class A+++ correspond to?

The energy label contains all the information about the product's energy consumption you need. On a scale from A to G, the most energy-efficient appliances are labelled A. For some products, the label goes up to A+++, with A+++ being the most energy-efficient.
