One project, two homes, five months, 50% savings

Insulating a home leads to energy savings of 50% in five months according to unique research by Knauf Insulation and a team of scientists in Hungary.

Insulating a home leads to energy savings of 50% in five months according to unique research by Knauf Insulation and a team of scientists in Hungary.

It has always been known that insulation saves energy and money, but the big question has always been by how much?

To find out, scientists compared the energy bills and savings of two typical 110m2homes in Hungary both occupied by a family of four.

However, there was one major difference.

One house was thoroughly insulated for free with Knauf Insulation’s Rock and Glass Wools to the highest ‘Category A’ standard. The other was left untouched falling into ‘Category G’ signifying hugely out-dated levels of energy efficiency, a situation common to most Hungarian homes.

Monitoring started on September 27 and by February 28 this year, the family living in the insulated house had only spent 365 Euro on 982m3 of gas winter heating compared to a bill of 690 Euro at the non-insulated home that used 1,848 m3.

Scientists from Budapest Technical University, the Hungarian Energy Efficiency Institute and Pannon Building Workshop Ltd all worked closely on the unique project monitoring the energy use required to keep both homes at 220C during the day and 19.50C at night.

Unsurprisingly, the ‘Reference House Programme’ has become a European media sensation followed closely by a public keen to save money.

In Hungary energy poverty has also topped political agendas with the government forcing energy suppliers to slash their prices by 20% in 2013. Another 10% cut is expected in April.

“Not only has this action caused huge losses for suppliers, it is completely unsustainable,” said Knauf Insulation’s spokesman in Hungary, László Kanyuk. “As our comparative house project has demonstrated with energy savings of 50%, the only viable permanent sustainable solution to reduced energy use is renovation.”
