With just a few clicks, you can find out about a property’s energy requirements, operating costs, and even savings opportunities after renovation – this is what K&H’s utility calculator offers, which has been filled in by thousands since its renewal last autumn. The data reveals what type of property users live in, how they heat it, what condition their home is in – and most importantly: what they can do to operate more sustainably.

More than 2,000 calculations in 2024 – mostly single-family homes

The calculator has been filled in 2,061 times so far, most of them (around 70 percent) for single-family homes. The proportion of energy efficiency calculations for apartment buildings was around 30%, which shows that the calculator addressed not only homeowners, but also city homeowners.

The typical Hungarian house of the utility calculator: built between 1980-1990

In the category of family houses, the overwhelming majority (85 percent) of the queries on the K&H utility calculator were related to houses built between 1980 and 1990. The average family house was 107 m², the average annual savings calculated by the calculator was 503 thousand forints, which is one third of the average utility costs.

Based on this, it can be stated: many people use the calculator for homes where there is actually space and opportunity for modernization.

Apartment owners are the most curious about the energy efficiency of their homes

The query regarding 605 apartments almost exclusively concerned apartment buildings built between 1960 and 1990, practically no significant calculations were received for other periods. Most people were curious about the energy efficiency of their panel apartments in housing estates built between 1960 and 1980: almost half of all queries related to such homes. Here, the average savings were less than for single-family homes: 26,441 forints. The smaller savings are understandable, since it is not so easy to replace a heating system or install solar panels as an individual homeowner.
