Net Zero Energy home makeovers

What is Net Zero Energy?

Energiesprong is a new standard for guaranteed net zero energy use, high comfort and a smooth implementation process. A Net Zero Energy (NZE) house generates as much energy as is needed for heating the house, providing hot water and power its household appliances. The details of the entire standard are tailored to each market and differ on details. This can be achieved by using new technologies such as prefabricated facades, insulated rooftops with solar panels, and smart heating and cooling installations.

The Energiesprong standard makes a house not just look like a new-build home; it actually has better quality and life expectancy as a new house.


Desirable, comfortable and affordable homes for everyone, for life. We are an independent market development team setting a new standard for comfortable, super energy efficient refurbishments (and new built solutions) with guaranteed performance. We also introduce a new financing approach and we work with governments to improve regulations for these solutions. This, to ensure people can get a home that not only fits our time, but is ready for our future.

Zero energy

Annualy, a Net Zero Energy house generates sufficient energy to heat the house, provide hot water and power its household appliances. A refurbishment comes with a 30-year performance warranty on both the indoor climate and the energy performance. Money normally spent on energy bills and maintenance work pays for the upgrade. This way, residents get a refreshed, warm and comfortable home at the same (or lower) cost of living.

How to pay for an Energiesprong house?

An Energiesprong renovation (or new built) is financed in two ways: through energy cost savings from tenants and by reduced maintenance and repairs costs for housing associations. Both are part of the business case. The objective is that tenants have the same monthly expenses – they pay the housing association an energy service plan instead of the bill of the energy supplier. The housing association can now use this new income stream to pay for the renovation.

Before: tenant pays rent and utility bill
After refurbishment

In most markets (including the Netherlands) legislation needs to allow the conversion of the monthly energy bill into a so-called energy plan for the housing association.
